Our global economy is outgrowing the capacity of the earth to support it, moving our early twenty-first century civilization ever closer to decline and possible collapse. In our preoccupation with quarterly earnings reports and year-to-year economic growth, we have lost sight of how large the human enterprise has become relative to the earth's resources. A century ago, annual growth in the world economy was measured in billions of dollars. Today it is measured in trillions.\n\nAs a result, we are consuming renewable resources faster than they can regenerate. Forests are shrinking, grasslands are deteriorating, water tables are falling, fisheries are collapsing, and soils are eroding. We are using up oil at a pace that leaves little time to plan beyond peak oil. And we are discharging greenhouse gases into the atmosphere faster than nature can absorb them, setting the stage for a rise in the earth's temperature well above any since agriculture began.\n\nOur twenty-first century civilization is not the first to move onto an economic path that was environmentally unsustainable. Many earlier civilizations also found themselves in environmental trouble. As Jared Diamond notes in //Collapse: How Societies Choose to Fail or Succeed//, some were able to change course and avoid economic decline. Others were not. We study the archeological sites of Sumerians, the Mayans, Easter Islanders, and other early civilizations that were not able to make the needed adjustments in time.^^1^^\n\nFortunately, there is a consensus emerging among scientists on the broad outlines of the changes needed. If economic progress is to be sustained, we need to replace the fossil-fuel-based, automobile-centered, throwaway economy with a new economic model. Instead of being based on fossil fuels, the new economy will be powered by abundant sources of renewable energy: wind, solar, geothermal, hydropower, and biofuels.\n\nInstead of being centered around automobiles, future transportation systems will be far more diverse, widely employing light rail, buses, and bicycles as well as cars. The goal will be to maximize mobility, not automobile ownership.\n\nThe throwaway economy will be replaced by a comprehensive reuse/recycle economy. Consumer products from cars to computers will be designed so that they can be disassembled into their component parts and completely recycled. Throwaway products such as single-use beverage containers will be phased out.\n\nThe good news is that we can already see glimpses here and there of what this new economy looks like. We have the technologies to build it - including, for example, gas-electric hybrid cars, advanced-design wind turbines, highly efficient refrigerators, and water-efficient irrigation systems.\n\nWe can see how to build the new economy brick by brick. With each wind farm, rooftop solar panel, paper recycling facility, bicycle path, and reforestation program, we move closer to an economy that can sustain economic progress.\n\nIf, instead, we continue on the current economic path, the question is not whether environmental deterioration will lead to economic decline, but when. No economy, however technologically advanced, can survive the collapse of its environmental support systems.\n\n[[1.1 - The Nature of the New World]]\n\n[[1.2 - Learning from China]]\n\n[[1.3 - Learning from the Past]]\n\n[[1.4 - The Emerging Politics of Scarcity]]\n\n[[1.5 - Getting the Price Right]]\n\n[[1.6 - Plan B - A Plan of Hope]]\n\n[[1.7 - Additional Resources]]\n\n[[1.8 - Notes]]\n\n[[2 - Beyond the Oil Peak]]\n\n----\nDownload pdf version of Chapter 1\n\n 16pp. (75 Kb)
We recently entered a new century, but we are also entering a new world, one where the collisions between our demands and the earth's capacity to satisfy them are becoming daily events. It may be another crop-withering heat wave, another village abandoned because of invading sand dunes, or another aquifer pumped dry. If we do not act quickly to reverse the trends, these seemingly isolated events will come more and more frequently, accumulating and combining to determine our future.\n\nResources that accumulated over eons of geological time are being consumed in a single human lifespan. We are crossing natural thresholds that we cannot see and violating deadlines that we do not recognize. These deadlines, determined by nature, are not politically negotiable.\n\nNature has many thresholds that we discover only when it is too late. In our fast-forward world, we learn that we have crossed them only after the fact, leaving little time to adjust. For example, when we exceed the sustainable catch of a fishery, the stocks begin to shrink. Once this threshold is crossed, we have a limited time in which to back off and lighten the catch. If we fail to meet this deadline, breeding populations shrink to where the fishery is no longer viable, and it collapses.\n\nWe know from earlier civilizations that the lead indicators of economic decline were environmental, not economic. The trees went first, then the soil, and finally the civilization itself. To archeologists, the sequence is all too familiar.\n\nOur situation today is far more challenging because in addition to shrinking forests and eroding soils, we must deal with falling water tables, more frequent crop-withering heat waves, collapsing fisheries, expanding deserts, deteriorating rangelands, dying coral reefs, melting glaciers, rising seas, more-powerful storms, disappearing species, and, soon, shrinking oil supplies. Although these ecologically destructive trends have been evident for some time, and some have been reversed at the national level, not one has been reversed at the global level.\n\nThe bottom line is that the world is in what ecologists call an "overshoot-and-collapse" mode. Demand has exceeded the sustainable yield of natural systems at the local level countless times in the past. Now, for the first time, it is doing so at the global level. Forests are shrinking for the world as a whole. Fishery collapses are widespread. Grasslands are deteriorating on every continent. Water tables are falling in many countries. Carbon dioxide (CO~~2~~) emissions exceed CO~~2~~ fixation everywhere.\n\nIn 2002, a team of scientists led by Mathis Wackernagel, who now heads the Global Footprint Network, concluded that humanity's collective demands first surpassed the earth's regenerative capacity around 1980. Their study, published by the U.S. National Academy of Sciences, estimated that global demands in 1999 exceeded that capacity by 20 percent. The gap, growing by 1 percent or so a year, is now much wider. We are meeting current demands by consuming the earth's natural assets, setting the stage for decline and collapse.^^2^^\n\nIn a rather ingenious approach to calculating the human physical presence on the planet, Paul MacCready, the founder and Chairman of AeroVironment and designer of the first solar-powered aircraft, has calculated the weight of all vertebrates on the land and in the air. He notes that when agriculture began, humans, their livestock, and pets together accounted for less than 0.1 percent of the total. Today, he estimates, this group accounts for 98 percent of the earth's total vertebrate biomass, leaving only 2 percent for the wild portion, the latter including all the deer, wildebeests, elephants, great cats, birds, small mammals, and so forth.^^3^^\n\nEcologists are intimately familiar with the overshoot-and-collapse phenomenon. One of their favorite examples began in 1944, when the Coast Guard introduced 29 reindeer on remote St. Matthew Island in the Bering Sea to serve as the backup food source for the 19 men operating a station there. After World War II ended a year later, the base was closed and the men left the island. When U.S. Fish and Wildlife Service biologist David Kline visited St. Matthew in 1957, he discovered a thriving population of 1,350 reindeer feeding on the four-inch-thick mat of lichen that covered the 332-square-kilometer (128-square-mile) island. In the absence of any predators, the population was exploding. By 1963, it had reached 6,000. He returned to St. Matthew in 1966 and discovered an island strewn with reindeer skeletons and not much lichen. Only 42 of the reindeer survived: 41 females and 1 not entirely healthy male. There were no fawns. By 1980 or so, the remaining reindeer had died off.^^4^^\n\nLike the deer on St. Matthew Island, we too are overconsuming our natural resources. Overshoot leads sometimes to decline and sometimes to a complete collapse. It is not always clear which it will be. In the former, a remnant of the population or economic activity survives in a resource-depleted environment. For example, as the environmental resource base of Easter Island in the South Pacific deteriorated, its population declined from a peak of 20,000 several centuries ago to today's population of fewer than 4,000. In contrast, the 500-year-old Norse settlement in Greenland collapsed during the 1400s, disappearing entirely in the face of environmental adversity.\n\nAs of 2005, some 42 countries have populations that are stable or declining slightly in size as a result of falling birth rates. But now for the first time ever, demographers are projecting population declines in some countries because of rising death rates, among them Botswana, Lesotho, Namibia, and Swaziland. In the absence of an accelerated shift to smaller families, this list of countries is likely to grow much longer in the years immediately ahead.^^6^^\n\nThe most recent mid-level U.N. demographic projections show world population increasing from 6.1 billion in 2000 to 9.1 billion in 2050. But such an increase seems highly unlikely, considering the deterioration in life-support systems now under way in much of the world. Will we not reach 9.1 billion because we quickly eradicate global poverty and lower birth rates? Or because we fail to do so and death rates begin to rise, as they are already doing in many African countries? We thus face two urgent major challenges: restructuring the global economy and stabilizing world population.^^7^^\n\nEven as the economy's environmental support systems are deteriorating, the world is pumping oil with reckless abandon. Leading geologists now think oil production may soon peak and turn downward. This collision between the ever-growing demand for oil and the earth's finite resources is but the latest in a long series of collisions. Although no one knows exactly when oil production will peak, supply is already lagging behind demand, driving prices upward.^^8^^\n\nIn this new world, the price of oil begins to set the price of food, not so much because of rising fuel costs for farmers and food processors but more because almost everything we eat can be converted into fuel for cars. In this new world of high oil prices, supermarkets and service stations will compete in commodity markets for basic food commodities such as wheat, corn, soybeans, and sugarcane. Wheat going into the market can be converted into bread for supermarkets or ethanol for service stations. Soybean oil can go onto supermarket shelves or it can go to service stations to be used as diesel fuel. In effect, owners of the world's 800 million cars will be competing for food resources with the 1.2 billion people living on less than $1 a day.\n\nFaced with a seemingly insatiable demand for automotive fuel, farmers will want to clear more and more of the remaining tropical forests to produce sugarcane, oil palms, and other high-yielding fuel crops. Already, billions of dollars of private capital are moving into this effort. In effect, the rising price of oil is generating a massive new threat to the earth's biological diversity.\n\nAs the demand for farm commodities climbs, it is shifting the focus of international trade concerns from the traditional goal of assured access to markets to one of assured access to supplies. Countries heavily dependent on imported grain for food are beginning to worry that buyers for fuel distilleries may outbid them for supplies. As oil security deteriorates, so, too, will food security.\n\nAs the role of oil recedes, the process of globalization will be reversed in fundamental ways. As the world turned to oil during the last century, the energy economy became increasingly globalized, with the world depending heavily on a handful of countries in the Middle East for energy supplies. Now as the world turns to wind, solar cells, and geothermal energy in this century, we are witnessing the localization of the world energy economy.\n\nThe globalization of the world food economy will also be reversed, as the higher price of oil raises the cost of transporting food internationally. In response, food production and consumption will become much more localized, leading to diets based more on locally produced food and seasonal availability.\n\nThe world is facing the emergence of a geopolitics of scarcity, which is already highly visible in the efforts by China, India, and other developing countries to ensure their access to oil supplies. In the future, the issue will be who gets access to not only Middle Eastern oil but also Brazilian ethanol and North American grain. Pressures on land and water resources, already excessive in most of the world, will intensify further as the demand for biofuels climbs. This geopolitics of scarcity is an early manifestation of civilization in an overshoot-and-collapse mode, much like the one that emerged among the Mayan cities competing for food in that civilization's waning years.^^10^^\n\nYou do not need to be an ecologist to see that if recent environmental trends continue, the global economy eventually will come crashing down. It is not knowledge that we lack. At issue is whether national governments can stabilize population and restructure the economy before time runs out. Looking at what is happening in China helps us to see the urgency of acting quickly.\n\n[[1.2 - Learning from China]]\n\n[[1.3 - Learning from the Past]]\n\n[[1.4 - The Emerging Politics of Scarcity]]\n\n[[1.5 - Getting the Price Right]]\n\n[[1.6 - Plan B - A Plan of Hope]]\n\n[[1.7 - Additional Resources]]\n\n[[1.8 - Notes]]\n\n[[2 - Beyond the Oil Peak]]
For many years environmentalists have pointed to the United States as the world's leading consumer, noting that 5 percent of the world's people were consuming nearly a third of the earth's resources. Although that was true for some time, it no longer is. China has replaced the United States as the leading consumer of basic commodities.^^11^^\n\nAmong the five basic food, energy, and industrial commodities - grain and meat, oil and coal, and steel - consumption in China has eclipsed that of the United States in all but oil. China has opened a wide lead with grain, consuming 380 million tons in 2005 versus 260 million tons in the United States. Among the big three grains, China leads in the consumption of both wheat and rice and trails the United States only in corn.^^12^^\n\nAlthough eating hamburgers is a defining element of the U.S. lifestyle, China's 2005 meat consumption of 67 million tons is far above the 38 million tons eaten in the United States. While\n\nU.S. meat intake is rather evenly distributed between beef, pork, and poultry, in China pork totally dominates. Indeed, half the world's pigs are now found in China.^^13^^\n\nWith oil, the United States was still solidly in the lead in 2004, using more than three times as much as China - 20.4 million barrels per day versus 6.5 million barrels. But U.S. oil use expanded by only 15 percent between 1994 and 2004, while use in China more than doubled. Having recently eclipsed Japan as an oil consumer, China now trails only the United States.^^14^^\n\nEnergy use in China also obviously includes coal, which supplies nearly two thirds of the country's energy. China's annual burning of 960 million tons easily exceeds the 560 million tons used in the United States. With this level of coal use and with oil and natural gas use also climbing fast, it is only a matter of time before China's carbon emissions match those of the United States. Then the world will have two major countries driving climate change.^^15^^\n\nChina's consumption of steel, a basic indicator of industrial development, is now nearly two and a half times that of the United States: 258 million tons to 104 million tons in 2003. As China has moved into the construction phase of development, building hundreds of thousands of factories and high-rise apartment and office buildings, steel consumption has climbed to levels never seen in any country.^^16^^\n\nWith consumer goods, China leads in the number of cell phones, television sets, and refrigerators. The United States still leads in the number of personal computers, though likely not for much longer, and in automobiles.^^17^^\n\nThat China has overtaken the United States in consumption of basic resources gives us license to ask the next question. What if China catches up with the United States in consumption per person? If the Chinese economy continues to grow at 8 percent a year, by 2031 income per person will equal that in the United States in 2004. If we further assume that consumption patterns of China's affluent population in 2031, by then 1.45 billion, will be roughly similar to those of Americans in 2004, we have a startling answer to our question.^^18^^\n\nAt the current annual U.S. grain consumption of 900 kilograms per person, including industrial use, China's grain consumption in 2031 would equal roughly two thirds of the current world grain harvest. If paper use per person in China in 2031 reaches the current U.S. level, this translates into 305 million tons of paper - double existing world production of 161 million tons. There go the world's forests. And if oil consumption per person reaches the U.S. level by 2031, China will use 99 million barrels of oil a day. The world is currently producing 84 million barrels a day and may never produce much more. This helps explain why China's fast-expanding use of oil is already helping to create a politics of scarcity.\n\nOr consider cars. If China one day should have three cars for every four people, as the United States now does, its fleet would total 1.1 billion vehicles, well beyond the current world fleet of 800 million. Providing the roads, highways, and parking lots for such a fleet would require paving an area roughly equal to China's land in rice, its principal food staple.^^20^^\n\nThe inevitable conclusion to be drawn from these projections is that there are not enough resources for China to reach U.S. consumption levels. The western economic model - the fossil-fuel-based, automobile-centered, throwaway economy - will not work for China's 1.45 billion in 2031. If it does not work for China, it will not work for India either, which by 2031 is projected to have even more people than China. Nor will it work for the other 3 billion people in developing countries who are also dreaming the "American dream." And in an increasingly integrated world economy, where countries everywhere are competing for the same resources - the same oil, grain, and iron ore - the existing economic model will not work for industrial countries either.^^21^^\n\n[[1.3 - Learning from the Past]]\n\n[[1.4 - The Emerging Politics of Scarcity]]\n\n[[1.5 - Getting the Price Right]]\n\n[[1.6 - Plan B - A Plan of Hope]]\n\n[[1.7 - Additional Resources]]\n\n[[1.8 - Notes]]\n\n[[2 - Beyond the Oil Peak]]
Our twenty-first century global civilization is not the first to face the prospect of environmentally induced economic decline. The question is how we will respond. We do have one unique asset at our command - an archeological record that shows us what happened to earlier civilizations that got into environmental trouble and failed to respond.\n\nAs Jared Diamond points out in //Collapse//, some of the early societies that were in environmental trouble were able to change their ways in time to avoid decline and collapse. Six centuries ago, for example, Icelanders realized that overgrazing on their grass-covered highlands was leading to extensive soil loss from the inherently thin soils of the region. Rather than lose the grasslands and face economic decline, farmers joined together to determine how many sheep the highlands could sustain and then allocated quotas among themselves, thus preserving their grasslands and avoiding what Garrett Hardin later termed the "tragedy of the commons."^^22^^\n\nThe Icelanders understood the consequences of overgrazing and reduced their sheep numbers to a level that could be sustained. We understand the consequences of burning fossil fuels and the resulting CO~~2~~ buildup in the atmosphere. Unlike the Icelanders who were able to restrict their livestock numbers, we have not been able to restrict our CO~~2~~ emissions.\n\nNot all societies have fared as well as the Icelanders, whose economy continues to produce wool and to thrive. The early Sumerian civilization of the fourth millennium BC was an extraordinary one, advancing far beyond any that had existed before. Its carefully engineered irrigation system gave rise to a highly productive agriculture, one that enabled farmers to produce a food surplus, supporting formation of the first cities. Managing the irrigation system required a sophisticated social organization. The Sumerians had the first cities and the first written language, the cuneiform script.^^23^^\n\nBy any measure it was an extraordinary civilization, but there was an environmental flaw in the design of its irrigation system, one that would eventually undermine its food supply. The water that backed up behind dams built across the Euphrates was diverted onto the land through a network of gravity-fed canals. Some water was used by the crops, some evaporated, and some percolated downward. In this region, where underground drainage was weak, percolation slowly raised the water table. As the water climbed to within inches of the surface, it began to evaporate into the atmosphere, leaving behind salt. Over time, the accumulation of salt on the soil surface lowered its productivity.\n\nAs salt accumulated and wheat yields declined, the Sumerians shifted to barley, a more salt-tolerant plant. This postponed Sumer's decline, but it was treating the symptoms, not the cause, of falling crop yields. As salt concentrations continued to build, the yields of barley eventually declined also. The resultant shrinkage of the food supply undermined the economic foundation of this once-great civilization. As land productivity declined, so did the civilization.^^25^^\n\nArcheologist Robert McC. Adams has studied the site of ancient Sumer on the central floodplain of the Euphrates River, an empty, desolate area now outside the frontiers of cultivation. He describes how the "tangled dunes, long disused canal levees, and the rubble-strewn mounds of former settlement contribute only low, featureless relief. Vegetation is sparse, and in many areas it is almost wholly absent... .Yet at one time, here lay the core, the heartland, the oldest urban, literate civilization in the world."^^26^^\n\nThe New World counterpart to Sumer is the Mayan civilization that developed in the lowlands of what is now Guatemala. It flourished from AD 250 until its collapse around AD 900. Like the Sumerians, the Mayans had developed a sophisticated, highly productive agriculture, this one based on raised plots of earth surrounded by canals that supplied water.^^27^^\n\nAs with Sumer, the Mayan demise was apparently linked to a failing food supply. For this New World civilization, it was deforestation and soil erosion that undermined agriculture. Changes in climate may also have played a role. Food shortages apparently triggered civil conflict among the various Mayan cities as they competed for food. Today this region is covered by jungle, reclaimed by nature.^^28^^\n\nDuring the later centuries of the Mayan civilization, a new society was evolving on faraway Easter Island, some 166 square kilometers of land in the South Pacific roughly 3,200 kilometers west of South America and 2,200 kilometers from Pitcairn Island, the nearest habitation. Settled around AD 400, this civilization flourished on a volcanic island with rich soils and lush vegetation, including trees that grew 25 meters tall with trunks 2 meters in diameter. Archeological records indicate that the islanders ate mainly seafood, principally dolphins - a mammal that could only be caught by harpoon from large sea-going canoes.^^29^^\n\nThe Easter Island society flourished for several centuries, reaching an estimated population of 20,000. As its human numbers gradually increased, tree cutting exceeded the sustainable yield of forests. Eventually the large trees that were needed to build the sturdy canoes disappeared, depriving islanders of access to the dolphins and dramatically shrinking their food supply. The archeological record shows that at some point human bones became intermingled with the dolphin bones, suggesting a desperate society that had resorted to cannibalism. Today the island has some 2,000 residents.^^30^^\n\nOne unanswerable question about these earlier civilizations was whether they knew what was causing their decline. Did the Sumerians understand that the rising salt content in the soil from water evaporation was reducing their wheat yields? If they knew, were they simply unable to muster the political support needed to lower water tables, just as the world today is struggling unsuccessfully to lower carbon emissions?\n\nThese are just three of the many early civilizations that moved onto an economic path that nature could not sustain. We, too, are on such a path. Any one of several trends of environmental degradation could undermine civilization as we know it. Just as the irrigation system that defined the early Sumerian economy had a flaw, so too does the fossil fuel energy system that defines our modern economy. For them it was a rising water table that undermined the economy; for us it is rising CO~~2~~ levels that threaten to disrupt economic progress. In both cases, the trend is invisible.\n\nWhether it resulted from the salting of Sumer's cropland, the deforestation and soil erosion of the Mayans, or the depleted forests and loss of the distant-water fishing capacity of the Easter Islanders, collapse of these early civilizations appears to have been associated with a decline in food supply. Today the annual addition of more than 70 million people to a world population of over 6 billion at a time when water tables are falling, temperatures are rising, and oil supplies will soon be shrinking suggests that the food supply again may be the vulnerable link between the environment and the economy.^^31^^\n\n[[1.4 - The Emerging Politics of Scarcity]]\n\n[[1.5 - Getting the Price Right]]\n\n[[1.6 - Plan B - A Plan of Hope]]\n\n[[1.7 - Additional Resources]]\n\n[[1.8 - Notes]]\n\n[[2 - Beyond the Oil Peak]]
The first big test of the international community's capacity to manage scarcity may come with oil or it could come with grain. If the latter is the case, this could occur when China - whose grain harvest fell by 34 million tons, or 9 percent, between 1998 and 2005 - turns to the world market for massive imports of 30 million, 50 million, or possibly even 100 million tons of grain per year. Demand on this scale could quickly overwhelm world grain markets. When this happens, China will have to look to the United States, which controls the world's grain exports of over 40 percent of some 200 million tons.^^32^^\n\nThis will pose a fascinating geopolitical situation. More than 1.3 billion Chinese consumers, who had an estimated $160-billion trade surplus with the United States in 2004 - enough to buy the entire U.S. grain harvest twice - will be competing with Americans for U.S. grain, driving up U.S. food prices. In such a situation 30 years ago, the United States simply restricted exports. But China is now banker to the United States, underwriting much of the massive U.S. fiscal deficit with monthly purchases of U.S. Treasury bonds.^^33^^\n\nWithin the next few years, the United States may be loading one or two ships a day with grain for China. This long line of ships stretching across the Pacific, like an umbilical cord providing nourishment, will intimately link the two economies. Managing this flow of grain so as to simultaneously satisfy the food needs of consumers in both countries, at a time when ethanol fuel distilleries are taking a growing share of the U.S. grain harvest, may become one of the leading foreign policy challenges of this new century.\n\nThe way the world accommodates the vast projected needs of China, India, and other developing countries for grain, oil, and other resources will help determine how the world addresses the stresses associated with outgrowing the earth. How low-income, importing countries fare in this competition for grain will also tell us something about future political stability. And, finally, the U.S. response to China's growing demands for grain even as they drive up food prices for U.S. consumers will tell us much about the capacity of countries to manage the emerging politics of scarcity.\n\nThe most imminent risk is that China's entry into the world market, combined with the growing diversion of farm commodities to biofuels, will drive grain prices so high that many low-income developing countries will not be able to import enough grain. This in turn could lead to escalating food prices and political instability on a scale that will disrupt global economic progress.\n\nEarlier civilizations that moved onto an economic path that was environmentally unsustainable did so largely in isolation. But in today's increasingly integrated, interdependent world economy, if we are facing civilizational decline, we are facing it together. The fates of all peoples are intertwined. This interdependence can be managed to our mutual benefit only if we recognize that the term "in the national interest" is in many ways obsolete.\n\n[[1.5 - Getting the Price Right]]\n\n[[1.6 - Plan B - A Plan of Hope]]\n\n[[1.7 - Additional Resources]]\n\n[[1.8 - Notes]]\n\n[[2 - Beyond the Oil Peak]]
The question facing governments is whether they can respond quickly enough to prevent threats from becoming catastrophes. The world has precious little experience in responding to aquifer depletion, rising temperatures, expanding deserts, melting polar ice caps, and a shrinking oil supply. These new trends will fully challenge the capacity of our political institutions and leadership. In times of crisis, societies sometimes have a Nero as a leader and sometimes a Churchill.\n\nThe central challenge, the key to building the new economy, is getting the market to tell the ecological truth. The dysfunctional global economy of today has been shaped by distorted market prices that do not incorporate environmental costs. Many of our environmental travails are the result of severe market distortions.\n\nOne of these distortions became abundantly clear in the summer of 1998 when China's Yangtze River valley, home to 400 million people, was wracked by some of the worst flooding in history. The resulting damages of $30 billion exceeded the value of the country's annual rice harvest.^^34^^\n\nAfter several weeks of flooding, the government in Beijing announced in mid-August a ban on tree cutting in the Yangtze River basin. It justified the ban by noting that trees standing are worth three times as much as trees cut. The flood control services provided by forests were three times as valuable as the lumber in the trees. In effect, the market price was off by a factor of three! With this analysis, no one could economically justify cutting trees in the basin.^^35^^\n\nA similar situation exists with gasoline. In the United States, the gasoline pump price was over $2 per gallon in mid-2005. But this reflects only the cost of pumping the oil, refining it into gasoline, and delivering the gas to service stations. It does not include the costs of tax subsidies to the oil industry, such as the oil depletion allowance; the subsidies for the extraction, production, and use of petroleum; the burgeoning military costs of protecting access to oil supplies; the health care costs for treating respiratory illnesses ranging from asthma to emphysema; and, most important, the costs of climate change.^^36^^\n\nIf these costs, which in 1998 the International Center for Technology Assessment calculated at roughly $9 per gallon of gasoline burned in the United States, were added to the $2 cost of the gasoline itself, motorists would pay about $11 a gallon for gas at the pump. Filling a 20-gallon tank would cost $220. In reality, burning gasoline is very costly, but the market tells us it is cheap, leading to gross distortions in the structure of the economy. The challenge facing governments is to incorporate such costs into market prices by systematically calculating them and incorporating them as a tax on the product to make sure its price reflects the full costs to society.^^37^^\n\nIf we have learned anything over the last few years, it is that accounting systems that do not tell the truth can be costly. Faulty corporate accounting systems that leave costs off the books have driven some of the world's largest corporations into bankruptcy, costing millions of people their lifetime savings, retirement incomes, and jobs. Distorted world market prices that do not incorporate major costs in the production of various products and the provision of services could be even costlier. They could lead to global bankruptcy and economic decline.\n\n[[1.6 - Plan B - A Plan of Hope]]\n\n[[1.7 - Additional Resources]]\n\n[[1.8 - Notes]]\n\n[[2 - Beyond the Oil Peak]]
Even given the extraordinarily challenging situation we face, there is much to be upbeat about. First, virtually all the destructive environmental trends are of our own making. All the problems we face can be dealt with using existing technologies. And almost everything we need to do to move the world economy onto an environmentally sustainable path has been done in one or more countries.\n\nWe see the components of Plan B - the alternative to business as usual - in new technologies already on the market. On the energy front, for example, an advanced-design wind turbine can produce as much energy as an oil well. Japanese engineers have designed a vacuum-sealed refrigerator that uses only one eighth as much electricity as those marketed a decade ago. Gas-electric hybrid automobiles, getting 55 miles per gallon, are easily twice as efficient as the average vehicle on the road.^^38^^\n\nNumerous countries are providing models of the different components of Plan B. Denmark, for example, today gets 20 percent of its electricity from wind and has plans to push this to 50 percent by 2030. Similarly, Brazil is on its way to automotive fuel self-sufficiency. With highly efficient sugarcane-based ethanol supplying 40 percent of its automotive fuel in 2005, it could phase out gasoline within a matter of years.^^39^^\n\nWith food, India - using a small-scale dairy production model that relies almost entirely on crop residues as a feed source - has more than quadrupled its milk production since 1970, overtaking the United States to become the world's leading milk producer. The value of India's dairy production in 2002 exceeded that of the rice crop.^^40^^\n\nOn another front, fish farming advances in China, centered on the use of an ecologically sophisticated carp polyculture, have made China the first country where fish farm output exceeds oceanic catch. Indeed, the 29 million tons of farmed fish produced in China in 2003 was equal to roughly 30 percent of the world's oceanic fish catch.^^41^^\n\nWe see what a Plan B world could look like in the reforested mountains of South Korea. Once a barren, almost treeless country, the 65 percent of South Korea now covered by forests has checked flooding and soil erosion, returning a high degree of environmental stability to the Korean countryside.^^42^^\n\nThe United States - which retired one tenth of its cropland, most of it highly erodible, and shifted to conservation tillage practices - has reduced soil erosion by 40 percent over the last 20 years. At the same time, the nation's farmers expanded the grain harvest by more than one fifth.^^43^^\n\nSome of the most innovative leadership has come at the urban level. Amsterdam has developed a diverse urban transport system; today 35 percent of all trips within the city are taken by bicycle. This bicycle-friendly transport system has greatly reduced air pollution and traffic congestion while providing daily exercise for the city's residents.^^44^^\n\nNot only are new technologies becoming available, but some of these technologies can be combined to create entirely new outcomes. Gas-electric hybrid cars with a second storage battery and a plug-in capacity, combined with investment in wind farms feeding cheap electricity into the grid, could mean that much of our daily driving could be done with electricity, with the cost of off-peak wind-generated electricity at the equivalent of 50¬Ę-a-gallon gasoline. Domestic wind energy can be substituted for imported oil.^^45^^\n\nThe challenge is to build a new economy and to do it at wartime speed before we miss so many of nature's deadlines that the economic system begins to unravel. This introductory chapter leads into five chapters outlining the leading environmental challenges facing our global civilization. Following these are seven chapters that outline Plan B, both describing where we want to go and offering a roadmap of how to get there.\n\nParticipating in the construction of this enduring new economy is exhilarating. So is the quality of life it will bring. We will be able to breathe clean air. Our cities will be less congested, less noisy, and less polluted. The prospect of living in a world where population has stabilized, forests are expanding, and carbon emissions are falling is an exciting one.\n\n[[1.7 - Additional Resources]]\n\n[[1.8 - Notes]]\n\n[[2 - Beyond the Oil Peak]]

Some time ago, I had a call from my son Brian, who had come across a huge new wind farm as he was driving on one of the interstate highways in west Texas. He described the rows of wind turbines receding toward the horizon. Interspersed among them were oil wells. The wind turbines were turning and the oil wells were pumping. My son was fascinated by the juxtaposition of the old and the new, the past and the future. I said, "If you return 30 years from now, the wind turbines will still be turning, but it is unlikely that the oil wells will be pumping." What he was looking at in a nutshell was the energy transition, the shift from the age of fossil fuels to renewables.\n\nThe energy transition is gaining momentum. When the Kyoto Protocol was negotiated in 1997, the proposed 5-percent reduction in carbon emissions from 1990 levels in industrial countries by 2012 seemed like an ambitious goal. Now it is widely seen as an outmoded, grossly inadequate goal. National governments, local governments, corporations, and environmental groups are coming up with plans to cut carbon emissions much further than was agreed to in Kyoto by turning to renewables and raising energy efficiency. Some individuals and groups are even beginning to think about how to cut carbon emissions by 70 percent, the amount that scientists say will be needed to stabilize climate.^^1^^\n\nIn July 2005, the European Commission proposed a new plan to cut energy use 20 percent by 2020 and to increase the renewable share of Europe's energy supply to 12 percent by 2010. Together, these two initiatives will reduce Europe's carbon emissions by nearly one third. Among the long list of measures to boost energy efficiency in these countries are replacing old, inefficient refrigerators, switching to high-efficiency light bulbs, and insulating roofs. Reaching the renewables goal requires a rather conservative addition of 15,000 megawatts of wind power, a fivefold expansion of ethanol production, and a threefold increase in biodiesel production. The Europeans' proposed 20 percent cut in energy use by 2020 contrasts sharply with the projected growth of 10 percent under a business-as-usual scenario.^^2^^\n\nThe proposed plan, which is scheduled for final approval in 2006, is designed to save 60 billion euros by 2020. It is also designed to stimulate economic growth, create new jobs, and, by reducing energy outlays, enhance European competitiveness in world markets. The 25-member European Union is second only to the United States in energy consumption.^^3^^\n\nIn 2005 the Japanese government also announced a national campaign to dramatically boost energy efficiency in its economy, already one of the world's most efficient. It urged its people to replace older, inefficient appliances and to buy hybrid cars. The //New York Times// described this as "all part of a patriotic effort to save energy and fight global warming." It noted that the large manufacturing firms were jumping on the energy efficiency bandwagon as a way of increasing sales of their latest high-efficiency models.^^4^^\n\nBeyond this initial effort, Japan has set goals for boosting appliance efficiency even further, cutting energy use of television sets by 17 percent, of personal computers by 30 percent, of air conditioners by 36 percent, and of refrigerators by a staggering 72 percent. Scientists are working on a vacuum-insulated refrigerator that will use only one eighth as much electricity as those marketed a decade ago.^^5^^\n\nAt the nongovernmental level, a plan developed for Canada by the David Suzuki Foundation and the Climate Action Network would halve carbon emissions by 2030 and would do it only with investments in energy efficiency that are profitable. And in early April 2003, the World Wildlife Fund released a peer-reviewed analysis by a team of scientists that proposed reducing carbon emissions from U.S. electric power generation 60 percent by 2020. This proposal centers on a shift to more energy-efficient power generation equipment, the use of more-efficient household appliances and industrial motors and other equipment, and in some situations a shift from coal to natural gas as an energy source. If implemented, it would result in national savings averaging $20 billion a year from now until 2020.^^6^^\n\nIn Ontario, Canada's most populous province, the ministry of energy plans to phase out the province's five large coal-fired power plants by 2009. The first, Lakeview Generating Station, was closed in April 2005; three more will close by the end of 2007, and the last will be shut down in early 2009. All three major political parties support the plan to replace coal with wind, natural gas, and efficiency gains. Jack Gibbons, director of the Ontario Clean Air Alliance, which endorses the ministry's plan, says of coal burning, "It's a nineteenth century fuel that has no place in twenty-first century Ontario."^^7^^\n\nCorporations are also getting involved. U.S.-based Interface, the world's largest manufacturer of industrial carpeting, cut carbon emissions by two thirds in its Canadian affiliate during the 1990s. It did so by examining every facet of its business - from electricity consumption to trucking procedures. Founder and chairman Ray Anderson says, "Interface Canada has reduced greenhouse gas emissions by 64 percent from the peak, and made money in the process, in no small measure because our customers support environmental responsibility." The Suzuki plan to cut Canadian carbon emissions in half by 2030 was inspired by the profitability of the Interface initiative.^^8^^\n\nAlthough stabilizing atmospheric carbon dioxide levels is a staggering challenge, it is entirely doable. With advances in wind turbine design, the evolution of gas-electric hybrid cars, advances in solar cell manufacturing, and gains in the efficiency of household appliances, we now have the basic technologies needed to shift quickly from a fossil-fuel-based to a renewable-energy-based economy. Cutting world carbon emissions in half by 2015 is entirely within range. Ambitious though this goal might seem, it is commensurate with the threat that climate change poses.\n\n[[10.1 - Raising Energy Productivity]]\n\n[[10.2 - Harnessing the Wind]]\n\n[[10.3 - Hybrid Cars and Wind Power]]\n\n[[10.4 - Converting Sunlight to Electricity]]\n\n[[10.5 - Energy from the Earth]]\n\n[[10.6 - Cutting Carbon Emissions Fast]]\n\n[[10.7 - Additional Resources]]\n\n[[10.8 - Notes]]\n\n[[11 - Designing Sustainable Cities]]\n\n----\nDownload pdf version of Chapter 10\n\n 22pp. (160 Kb)
The enormous potential for raising energy productivity becomes clear in comparisons of energy use among countries. Some nations in Europe have essentially the same living standard as the United States yet use scarcely half as much energy per person. But even the countries that use energy most efficiently are not close to realizing the full potential for doing so.^^9^^\n\nWhen the Bush administration released a new energy plan in April 2001 that called for construction of 1,300 new power plants by 2020, Bill Prindle of the Washington-based Alliance to Save Energy responded by pointing out how the country could eliminate the need for those plants and save money in the process. He ticked off several steps that would reduce the demand for electricity: Improving efficiency standards for household appliances would eliminate the need for 127 power plants. More stringent residential air conditioner efficiency standards would eliminate 43 power plants. Raising commercial air conditioner standards would eliminate the need for 50 plants. Using tax credits and energy codes to improve the efficiency of new buildings would save another 170 plants. Similar steps to raise the energy efficiency of existing buildings would save 210 plants. These five measures from the longer list suggested by Prindle would not only eliminate the need for 600 power plants, they would also save money. Although these calculations were made in 2001, they are still valid simply because there has been so little progress in raising U.S. energy efficiency since then.^^10^^\n\nOf course, each country will have to fashion its own plan for raising energy productivity. Nevertheless, there are a number of common components. Some are quite simple but highly effective, such as using more energy-efficient household appliances, eliminating the use of incandescent light bulbs, shifting to gas-electric hybrid cars, and redesigning urban transport systems to raise efficiency and increase mobility.\n\nAlthough there was an impressive round of efficiency gains in household appliances after the oil price jumps during the 1970s, the world generally lost interest as oil prices declined after 1980. Rising oil and natural gas prices are rekindling interest in this issue. Fortuitously, engineering advances since then have brought another wave of efficiency gains, such as those mentioned for Japan, that promise to substantially reduce electricity use. If national governments raise appliance efficiency standards to fully exploit the latest technologies, it would sharply cut carbon emissions worldwide.\n\nOne simple energy-saving step is to replace all remaining incandescent light bulbs with compact fluorescent lamps (CFLs), which use only one third as much electricity and last 10 times as long. In the United States, where 20 percent of all electricity is used for lighting, if each household replaced the still widely used incandescents with compact fluorescents, electricity for lighting would be easily cut in half. The combination of greater longevity and lower electricity use greatly outweighs the higher costs of the CFLs, yielding a risk-free investment return of some 25-40 percent a year. Worldwide, replacing incandescent light bulbs with CFLs in, say, the next three years would facilitate the closing of hundreds of climate-disrupting coal-fired power plants.^^11^^\n\nA second obvious area for raising energy efficiency is automobiles. If over the next decade the United States, for example, were to shift from the current fleet of cars powered with gasoline engines to gas-electric hybrids with the fuel efficiency of the Toyota Prius, gasoline use could easily be cut in half. Sales of hybrid cars, introduced into the U.S. market in 1999, reached an estimated 88,000 in 2004. Higher gasoline prices and mounting climate change worries are driving sales upward. With U.S. auto manufacturers coming onto the market with several new models, hybrid vehicle sales are projected to exceed 1 million by 2008.^^12^^\n\nAnother attractive way to raise energy efficiency is to redesign urban transport systems, moving from the existing system centered on single-occupant automobiles to a more diverse bicycle- and pedestrian-friendly system that would include well-developed light-rail subway systems complemented with buses. Such a system would increase mobility, reduce energy use and air pollution, and provide more opportunities for exercise, a win-win-win situation. Taking automobiles off the street would facilitate the conversion of parking lots into parks, creating more friendly cities.\n\n[[10.2 - Harnessing the Wind]]\n\n[[10.3 - Hybrid Cars and Wind Power]]\n\n[[10.4 - Converting Sunlight to Electricity]]\n\n[[10.5 - Energy from the Earth]]\n\n[[10.6 - Cutting Carbon Emissions Fast]]\n\n[[10.7 - Additional Resources]]\n\n[[10.8 - Notes]]\n\n[[11 - Designing Sustainable Cities]]
World wind-generating capacity, growing at 29 percent a year, has jumped from less than 5,000 megawatts in 1995 to more than 47,000 megawatts in 2004, a ninefold increase. (See Figure 10-1.) Wind's annual growth rate of 29 percent compares with 1.7 percent for oil, 2.5 percent for natural gas, 2.3 percent for coal, and 1.9 percent for nuclear power. There are six reasons why wind is growing so fast. It is abundant, cheap, inexhaustible, widely distributed, clean, and climate-benign. No other energy source has all these attributes.^^13^^\n\n<<tiddler Figure 10-1>>\n\nEurope is leading the world into the age of wind energy. Germany, which overtook the United States in 1997, leads the world with 16,600 megawatts of generating capacity. Spain, a rising wind power in southern Europe, overtook the United States in 2004. Denmark, which now gets an impressive 20 percent of its electricity from wind, is also the world's leading manufacturer and exporter of wind turbines.^^14^^\n\nIn its 2005 projections, the Global Wind Energy Council showed Europe's wind-generating capacity expanding from 34,500 megawatts in 2004 to 75,000 megawatts in 2010 and 230,000 megawatts in 2020. By 2020, just 15 years from now, wind-generated electricity is projected to satisfy the residential needs of 195 million consumers, half of Europe's population.^^15^^\n\nAfter developing most of its existing 34,500 megawatts of capacity on land, Europe is now tapping offshore wind as well. A 2004 assessment of the region's offshore potential by the Garrad Hassan wind energy consulting group concluded that if governments move aggressively to develop their vast offshore resources, wind could be supplying all of Europe's residential electricity by 2020.^^16^^\n\nThe United Kingdom, moving fast to develop its offshore wind capacity, accepted bids in April 2001 for sites designed to produce 1,500 megawatts of wind-generating capacity. In December 2003, the government took bids for 15 additional offshore sites with a generating capacity that could exceed 7,000 megawatts. Requiring an investment of over $12 billion, these offshore wind farms could satisfy the residential electricity needs of 10 million of the country's 60 million people. At the end of 2004, the United Kingdom had an offshore generating capacity of 124 megawatts, with an additional 180 megawatts under construction.^^17^^\n\nThe push to develop wind in Europe is spurred by concerns about climate change. The record heat wave in Europe in August 2003 that scorched crops and claimed 49,000 lives has accelerated the replacement of climate-disrupting coal with clean energy sources. Other countries that are turning to wind in a major way include Canada, Brazil, Argentina, Australia, India, and China.^^18^^\n\nOne of wind's great appeals is its abundance. When the U.S. Department of Energy released its first wind resource inventory in 1991, it noted that three wind-rich states - North Dakota, Kansas, and Texas - had enough harnessable wind energy to satisfy national electricity needs. Those who had thought of wind as a marginal source of energy obviously were surprised by this finding.^^19^^\n\nIn retrospect, we now know that this was a gross underestimate of the wind potential because it was based on the technologies of 1991. Advances in wind turbine design since then enable turbines to operate at lower wind speeds, to convert wind into electricity more efficiently, and to harness a much larger wind regime. In 1991, wind turbines may have averaged scarcely 40 meters in height. Today, new turbines are 100 meters tall, perhaps tripling the harvestable wind. We now know that the United States has enough harnessable wind energy to meet not only national //electricity// needs, but national //energy// needs.^^20^^\n\nWhen the wind industry began in California in the early 1980s, wind-generated electricity cost 38¬Ę per kilowatt-hour. Since then it has dropped to 4¬Ę or below at prime wind sites. And some U.S. long-term supply contracts have been signed for 3¬Ę per kilowatt-hour. Wind farms at prime sites may be generating electricity at 2¬Ę per kilowatt-hour by 2010, making it one of the world's cheapest sources of electricity.^^21^^\n\nLow-cost electricity from wind can be used to electrolyze water to produce hydrogen, which provides a way of both storing and transporting wind energy. At night, when the demand for electricity drops, the hydrogen generators can be turned on to build up reserves. Once in storage, hydrogen can be used to fuel power plants. Wind-generated hydrogen can thus become a backup for wind power, with hydrogen-powered electricity generation kicking in when wind power ebbs. Wind-generated hydrogen can also serve as an alternative to natural gas, especially if rising prices make gas prohibitively costly for electricity generation.\n\nThe principal cost for wind-generated electricity is the upfront capital outlay for initial construction. Since wind is a free fuel, the only ongoing cost is for turbine maintenance. Given the recent volatility of natural gas prices, the stability of wind power prices is particularly appealing. With the near certainty of even higher costs of natural gas in the future, natural-gas-fired plants may one day be used only as a backup for wind-generated electricity.\n\nThe United States is lagging in developing wind energy simply because the wind production tax credit (PTC) of 1.5¬Ę per kilowatt-hour, which was adopted in 1992 to establish parity with subsidies to fossil fuel, has lapsed three times in five years. Uncertainty about the tax credit has disrupted planning throughout the wind power industry. With the two-year extension of the PTC in mid-2005, however, through the end of 2007, growth in wind power investments is escalating rapidly. Given wind's enormous potential and the associated benefits of climate stabilization, it is time to consider an all-out effort to develop wind resources. Instead of doubling every 30 months or so, perhaps we should be doubling wind electric generation each year for the next several years, much as the number of computers linked to the Internet doubled each year from 1985 to 1995. Costs would then drop precipitously, giving electricity generated from wind an even greater advantage over fossil fuels.^^23^^\n\nEnergy consultant Harry Braun points out that since wind turbines are similar to automobiles in the sense that each has an electrical generator, a gearbox, an electronic control system, and a brake, they can be mass-produced on assembly lines. Indeed, the slack in the U.S. automobile industry is sufficient to produce a million wind turbines per year. The lower cost associated with mass production could drop the cost of wind-generated electricity below 2¬Ę per kilowatt-hour. Assembly-line production of wind turbines at "wartime" speed would quickly lower urban air pollution, carbon emissions, and the prospect of oil wars.^^24^^\n\nThe economic incentives to spur such growth could come in part from simply restructuring global energy subsidies - shifting the $210 billion in annual fossil fuel subsidies to the development of wind and other renewable sources of energy. The investment capital could come from private capital markets but also from companies already in the energy business. Shell, for example, has become a major player in the world wind energy economy. In 2002, General Electric, one of the world's largest corporations, entered the wind business, becoming overnight a major wind turbine manufacturer.^^25^^\n\nThese goals may seem farfetched, but here and there around the world ambitious efforts are beginning to take shape. In the United States, a 3,000-megawatt wind farm is in the early planning stages. Located in South Dakota near the Iowa border, it is being initiated by Clipper Wind, led by James Dehlsen, a wind energy pioneer in California. Designed to feed power into the industrial Midwest around Chicago, this project is not only large by wind power standards, it is one of the largest energy projects of any kind in the world today. In the eastern United States, Cape Wind is planning a 420-megawatt wind farm off the coast of Cape Cod, Massachusetts.^^26^^\n\nSome 24 states now have commercial-scale wind farms feeding electricity into the U.S. grid. Although there is occasionally a NIMBY problem ("not in my backyard"), the PIMBY response ("put it in my backyard") is much more pervasive. This is not surprising, since a single large turbine can easily generate $100,000 worth of electricity in a year.^^27^^\n\nThe competition among farmers in places like Iowa or ranchers in Colorado for wind farms is intense. Farmers, with no investment on their part, typically receive $3,000-5,000 a year in royalties from the local utility for siting a single, large, advanced-design wind turbine, which occupies a quarter-acre of land. This land would produce 40 bushels of corn worth $120 or, in ranch country, beef worth perhaps $15.^^28^^\n\nIn addition to the additional income, tax revenue, and jobs that wind farms bring, money spent on electricity generated from wind farms stays in the community, creating a ripple effect throughout the local economy. Within a matter of years, thousands of ranchers could be earning far more from electricity sales than from cattle sales.\n\nThe question is not whether wind is a potentially vast source of climate-benign energy that can be used to stabilize climate. It is. But will we develop it fast enough to head off economically disruptive climate change?\n\n[[10.3 - Hybrid Cars and Wind Power]]\n\n[[10.4 - Converting Sunlight to Electricity]]\n\n[[10.5 - Energy from the Earth]]\n\n[[10.6 - Cutting Carbon Emissions Fast]]\n\n[[10.7 - Additional Resources]]\n\n[[10.8 - Notes]]\n\n[[11 - Designing Sustainable Cities]]
With the price of oil over $60 a barrel at this writing in September 2005, with political instability in the Middle East on the rise, with little slack in the world oil economy, and with temperatures rising, the world needs a new energy economy. Fortunately, the foundation for a new transportation energy economy has been laid with two new technologies - the gas-electric hybrid engines pioneered by Toyota and advanced-design wind turbines.^^29^^\n\nThese technologies deployed together can dramatically reduce world oil use. As noted earlier, the United States could easily cut its gasoline use in half by converting the U.S. automobile fleet to hybrid cars as efficient as the Toyota Prius. No change in the number of vehicles, no change in miles driven - just doing it with the most efficient propulsion technology on the market.^^30^^\n\nIn fact, there are now several gas-electric hybrid car models on the market in addition to the Prius, including the Honda Insight and a hybrid version of the Honda Civic. According to the Environmental Protection Agency, the Prius - a midsize car on the cutting-edge of automotive technology - gets an astounding 55 miles per gallon in combined city/highway driving compared with 22 miles per gallon for the average new passenger vehicle. No wonder there are lists of eager buyers willing to wait several months for delivery.\n\nRecently, Ford released a hybrid model of its Escape SUV, and Honda released a hybrid version of its popular Accord sedan. General Motors will offer hybrid versions of several of its cars beginning with the Saturn VUE in 2006, followed by the Chevy Tahoe and Chevy Malibu.^^32^^\n\nEarlier in this chapter we outlined how to cut U.S. gasoline use in half by shifting to gas-electric hybrid vehicles over the next decade. As we shift to these cars, the stage is set for the second step to reduce gasoline use, namely the use of wind-generated electricity to power automobiles. If we add to the gas-electric hybrid a second battery to increase its electricity storage and a plug-in capacity so the batteries can also be recharged from the grid, motorists could then do their commuting, grocery shopping, and other short-distance travel largely with electricity, saving gasoline for the occasional long trip. Even more exciting, recharging batteries with off-peak wind-generated electricity would cost the equivalent of gasoline at 50¬Ę per gallon. This modification of hybrids could reduce remaining gasoline use by perhaps another 40 percent (or 20 percent of the original level of use), for a total reduction of gasoline use of 70 percent.^^33^^\n\nThese are not the only technologies that can dramatically cut gasoline use. Amory Lovins, a highly regarded pioneer in devising ways of reducing energy use, observes that most efforts to reduce automotive fuel efficiency focus on designing more-efficient engines, largely overlooking the potential of fuel savings from reducing vehicle weight. He notes that substituting advanced polymer composites for steel in constructing the body of automobiles can "roughly double the efficiency of a normal-weight hybrid without materially raising its total manufacturing cost." If we build gas-electric hybrids using the new advanced polymer composites, then we can cut the remaining 30 percent of fuel use by another half, for a total reduction of 85 percent.^^34^^\n\nUnlike the widely discussed fuel cell/hydrogen transportation model, the gas-electric hybrid/wind model does not require a costly new infrastructure, since the network of gasoline service stations and the electricity grid are already in place. To fully exploit this technology, the United States would need to integrate its weak regional grids into a strong national one, which it needs to do anyway to reduce the risk of blackouts. This, combined with the building of thousands of wind farms across the country, would allow the nation's fleet of automobiles to run largely on wind energy.\n\nOne of the few weaknesses of wind energy - its irregularity - is largely offset with the use of plug-in gas-electric hybrids, since the vehicle batteries become a storage system for wind energy. Beyond this, there is always the tank of gasoline as a backup.\n\nThe combination of gas-electric hybrids with a second storage battery and a plug-in capacity, the development of wind resources, and the use of advanced polymer composites to reduce vehicle weight has been discussed in a U.S. context but it is a model that can be used throughout the world. It is particularly appropriate for countries that are richly endowed with wind energy, such as China, Russia, Australia, Argentina, and many of those in Europe.^^36^^\n\nMoving to the highly efficient plug-in gas-electric hybrids, combined with the construction of thousands of wind farms across the country to feed electricity into a strong, integrated national grid, could cut U.S. gasoline use by 85 percent. It would also rejuvenate farm and ranch communities and shrink the U.S. balance-of-trade deficit. Even more important, it could cut automobile carbon emissions by some 85 percent, making the United States a model for other countries.\n\n[[10.4 - Converting Sunlight to Electricity]]\n\n[[10.5 - Energy from the Earth]]\n\n[[10.6 - Cutting Carbon Emissions Fast]]\n\n[[10.7 - Additional Resources]]\n\n[[10.8 - Notes]]\n\n[[11 - Designing Sustainable Cities]]
Wind is not the only vast untapped source of energy. When a team of three scientists at Bell Labs in Princeton, New Jersey, discovered in 1952 that sunlight striking a silicon surface could generate electricity, they opened the door to another near limitless source of energy - photovoltaic (or solar) cells. "No country uses as much energy as is contained in the sunlight that strikes its buildings each day," writes Denis Hayes, former Director of the U.S. government's Solar Energy Research Institute.^^37^^\n\nSales of solar cells worldwide jumped by a phenomenal 57 percent in 2004, pushing the generating capacity installed during the year to 1,200 megawatts. With this addition, world solar-cell generating capacity, which has doubled in the last two years, now exceeds 4,300 megawatts, roughly the equivalent of 13 coal-fired power plants. (See Figure 10-2.) A decade ago the United States had roughly half of the world market, but this has now dropped to 12 percent as Japan and Germany have surged ahead with ambitious solar programs.^^38^^\n\nSolar cells are used either in stand-alone systems or in systems that can feed into the grid. In its early years, the solar cell industry was dominated by non-grid uses to supply electricity to communication satellites and in remote sites such as national forests or parks, offshore lighthouses, summer homes in isolated mountain regions, or islands.\n\n<<tiddler Figure 10-2>>\n\nOver the last decade, solar cell installations that feed into the grid have grown rapidly in response to incentives offered by governments, and they now account for more than three fourths of all new installations. Two-way meters that enable utility customers to feed surpluses into the grid for a fixed rate have spurred rapid growth in solar cell use. The U.S. Energy Policy Act of 2005 established two-way metering for any customer requesting it. Some countries have established a fixed price for utilities to pay for electricity fed into the grid. In Germany, this has been set well above the market price to reflect the value of clean electricity and to get the fledgling solar cell industry off the ground.^^39^^\n\nThe residential use of solar cells is expanding at a breakneck pace in some countries. In Japan, where companies have commercialized a solar roofing material, the idea of making the roof the power plant for the home is increasingly popular. This, combined with Japan's 70,000 Roofs Program launched in 1994 to subsidize the installations, got the country off to a fast start, making it a world leader in solar-generated electricity.\n\nIn 1998, Germany initiated a 100,000 Roofs Program, which gave consumers 10-year loans for buying photovoltaic systems at reduced interest rates. This ended in 2003 when the goal of 100,000 solar roofs was reached. With this fast-growing market, solar cell costs now have fallen to where German manufacturers are quite competitive internationally.\n\nWithin the United States, California is also providing attractive incentives for the residential installation of solar cells. In a climate where peak capacity on hot summer days presses against the limits of the grid, solar cells are seen as an alternative to fossil fuel plants, mostly gas-fired, that operate only during the peak daytime demand. Happily, solar cells generate the most electricity during the hottest times of the day, making them ideal for satisfying peak power demands.^^42^^\n\nSolar cell installations may be even more economical in large buildings. In Manchester, England, a 40-story office building in need of renovation will be covered with photovoltaic material. With three sides of this 400-foot building covered with this material, the building has a huge generating surface. An official of the building owner and occupant, the Co-operative Insurance Society, noted with a smile that it would produce enough electricity each year to make 9 million cups of tea.^^43^^\n\nIn recent years, a vast new off-grid solar cell market has opened up in developing-country villages, where the cost of building a centralized power plant and a grid to deliver relatively small amounts of electricity to individual consumers is prohibitive. With solar cells costs falling, however, it is now often cheaper to provide electricity from solar cell installations than from a centralized source.\n\nIn Andean villages, solar installations are replacing candles as a source of lighting. For villagers who are paying for the installation over 30 months, the monthly payment is roughly equal to the cost of a month's supply of candles. Once the solar cells are paid for, the villagers then have an essentially free source of power - one that can supply electricity for decades. Similarly, in villages in India, where light now comes from kerosene lamps, soaring oil prices mean that kerosene from imported oil may now cost far more than solar cells.^^44^^\n\nToday more than 1 million homes in villages in the developing world are getting their electricity from solar cells, but this represents less than 1 percent of the 1.7 billion people who do not yet have electricity. The principal obstacle to the spread of solar cell installations in villages is not the cost per se, but the lack of small-scale credit programs to finance them. If this credit shortfall is quickly overcome, village purchases of solar cells will soar.^^45^^\n\nThe future of solar cells is promising. Japan, for example, where residential installations exceeded 1,000 megawatts at the end of 2004, plans to get 10 percent of its electricity from solar cells by 2030. Germany now has 700 megawatts of installed capacity and is growing fast. The United States, a distant third, introduced a solar tax credit in the Energy Policy Act of 2005. The first such credit in 20 years, it promises to rejuvenate the U.S. solar industry.\n\nThe cost of solar cells has been dropping for several decades and is expected to continue falling for the indefinite future. With each doubling of cumulative production, the manufacturing economics of scale drop the price an additional 20 percent. In addition, technologies for producing solar cells that convert more sunlight into electricity and do so at a lower cost are being worked on at numerous research facilities in several countries.^^47^^\n\nIn addition to generating electricity from solar cells, solar energy can also be concentrated to boil water and produce steam, driving a turbine to generate electricity. There are various designs used in solar-thermal power plants, including power towers, which consist of an elevated facility containing water that is heated by an array of mirrors, and solar troughs. Usually computer-controlled, the mirrors shift their position as the sun moves across the sky to maximize the sunlight focused on the boiler. Some 350 megawatts of generating capacity in California has been operating very successfully since nine solar trough plants were built in the mid-1980s and early 1990s. New initiatives to develop solar thermal power plants are now under way in Spain.^^48^^\n\nOne of the most popular ways of harnessing solar energy is the use of rooftop solar thermal collectors for both water and space heating. Janet Sawin of Worldwatch Institute reports that the global installations of 150 million square meters, excluding the one fourth that is used for swimming pools, supplies water or space heating for 32 million households.^^49^^\n\nFor years both Israel and Cyprus, countries rich in sunlight, have been encouraging solar water heaters as a way of reducing the need for imported fossil fuels. Germany, which has 5.4 million square meters of solar water heating panels, ranks second in installed capacity. This panel area totals 540 hectares or roughly 1,300 acres.^^50^^\n\nChina, far and away the world leader in this technology, is planning to quadruple its current 52 million square meters of collectors by 2015, reports Sawin. Spain, a leading manufacturer of solar thermal panels, is making a bid for industry leadership by requiring the inclusion of rooftop solar water heaters on all new buildings, residential and commercial, beginning in 2005. A two-meter panel on a single-family residence can reduce annual water heating bills by 70 percent. In effect, Spain is substituting its abundant sunlight for imported oil.^^51^^\n\nThe technologies for converting sunlight into electricity or using it to heat water and building space are now well developed. And the economics are falling into place. What is needed to accelerate this is a set of incentives in all countries that reflects the value to society of reducing dependence on oil and of reducing carbon emissions.\n\n[[10.5 - Energy from the Earth]]\n\n[[10.6 - Cutting Carbon Emissions Fast]]\n\n[[10.7 - Additional Resources]]\n\n[[10.8 - Notes]]\n\n[[11 - Designing Sustainable Cities]]
When we think of renewable energy, we typically think of those sources that derive directly or indirectly from the sun. But the earth itself is a source of heat energy (mostly from radioactivity deep within the earth), which gradually escapes either through conduction or through hot springs and geysers that bring internal heat to the earth's surface. Geothermal energy is inexhaustible and will last as long as the earth itself.\n\nAside from being an ideal source for base load (continuous) power, geothermal energy is environmentally attractive for several reasons. Its carbon dioxide, sulfur dioxide, and nitrogen oxide emissions are negligible to non-existent. Water use for geothermal electric generation is 1 percent that of natural-gas-fired power plants.^^52^^\n\nThe potential of geothermal energy is extraordinary. Japan alone has an estimated geothermal electric-generating capacity of 69,000 megawatts, enough to satisfy one third of its electricity needs. Among the countries rich in geothermal energy are those bordering the Pacific in the so-called Ring of Fire. These include (on the east) Chile, Peru, Ecuador, Colombia, all the Central American countries, Mexico, the western United States, and Canada and (on the west) Russia, China, South Korea, Japan, the Philippines, Indonesia, Australia, and New Zealand. Other geothermally rich countries include those along the Great Rift of Africa and the Eastern Mediterranean. Fortunately, many countries now have enough experience and engineering capacity to tap this vast resource.^^53^^\n\nLike solar energy, geothermal energy is used both to generate electricity and to directly heat buildings, greenhouses, and aquacultural ponds. It is also used as a source of heat for industrial processes. After Italy pioneered the use of geothermal energy to generate electricity in 1904, the practice spread to some 25 countries. The global capacity of 8,400 megawatts in 2003 represents a 44-percent growth over the 5,800 megawatts available in 1990.^^54^^\n\nTwo countries - the United States with 2,000 megawatts and the Philippines with 1,900 megawatts - account for almost half of world generating capacity. In the Philippines, geothermal provides a world-leading 27 percent of the country's electricity supply. California, the most populous state, gets 5 percent of its electricity from geothermal power plants. Most of the remaining geothermal power generation is concentrated in five countries: Italy, Mexico, Indonesia, Japan, and New Zealand.^^55^^\n\nThe direct use of geothermal heat for various heating purposes worldwide is even larger, equivalent to 12,000 megawatts of electricity generation. Its use in heat pumps, which extract and concentrate heat from warm water for various uses, is the largest single use. More than 30 countries tap geothermal energy for heating.^^56^^\n\nIceland and France are the leaders. In Iceland, 93 percent of the country's homes are heated with geothermal energy, saving over $100 million per year in avoided oil imports. Geothermal energy accounts for more than one third of Iceland's total energy use. Following the two oil price hikes in the 1970s, some 70 geothermal heating facilities were constructed in France, providing both heat and hot water for an estimated 200,000 residences. In the United States, individual homes are supplied directly with geothermal heat in Reno, Nevada, and in Klamath Falls, Oregon. Other countries that have extensive geothermally based district-heating systems include China, Japan, and Turkey.\n\nGeothermal energy is an ideal source of heat for greenhouses, particularly in northern climes. Russia, Hungary, Iceland, and the United States all use geothermally heated greenhouses to produce fresh vegetables in winter. With rising oil prices boosting fresh produce transport costs, this option will likely become more popular in the years ahead.^^58^^\n\nSome 16 countries use geothermal energy for aquaculture. Among these are China, Israel, and the United States. In California, for example, 15 fish farms produce tilapia, striped bass, and catfish with warm water from underground. This warmer water enables fish to grow without interruption during the winter and to mature more quickly. Collectively these California farms produce 4.5 million kilograms of fish per year.^^59^^\n\nThe number of countries turning to geothermal energy both for electricity and for direct use is increasing rapidly. So, too, is the range of uses. Once the value of geothermal energy is discovered, its use is often quickly diversified. Romania, for example, uses its geothermal energy for district heating, for greenhouses, and to supply hot water for homes and factories. With heat pumps, the earth can serve as both a heat source and a sink to provide heating in winter and cooling in summer.^^60^^\n\nGeothermal energy is widely used for bathing and swimming. Japan, for example, has 2,800 spas, 5,500 public bathhouses, and 15,600 hotels and inns that use hot geothermal water. Iceland uses geothermal energy to heat some 100 public swimming pools, most of them year-round open-air pools. Hungary heats 1,200 swimming pools with geothermal energy.\n\nIndonesia, with more than 222 million people, could easily get all of its electricity from geothermal energy. Situated on the western edge of the Pacific, with 500 volcanoes, 128 of them active, Indonesia has a master plan for 11 geothermal power plants with a generation capacity of just over 300 megawatts each - a total of 3,400 megawatts. This plan was derailed by the Asian financial crisis of 1997, but supporters are now attempting to revive it. With its oil production falling, Indonesia needs to quickly develop alternative sources of energy. Unlike investments in oil, those in geothermal energy are tapping an energy source that can last forever.^^62^^\n\n[[10.6 - Cutting Carbon Emissions Fast]]\n\n[[10.7 - Additional Resources]]\n\n[[10.8 - Notes]]\n\n[[11 - Designing Sustainable Cities]]
By far the cheapest and fastest way to cut carbon emissions is to raise the efficiency of energy use. Not only is it cheap, it is often profitable. The other option is to develop renewable sources of energy. Within this framework, perhaps the most complex question is which alternative automotive fuels to develop. Until recently, the only widely considered alternative to oil since the initial oil price hikes in the 1970s was biofuels. Now with the advent of gas-electric hybrid plug-ins, wind-generated electricity becomes an appealing option because of its abundance and low cost.\n\nThe frugal use of land by wind is impressive. Within the United States, a quarter-acre of land in the corn belt can be used to site an advanced-design wind turbine that will produce $100,000 worth of electricity per year or it can be used to produce 40 bushels of corn that will yield 100 gallons of ethanol worth perhaps $200. If the goal is to minimize competition from the automotive fuel economy for food resources, wind-generated electricity is the obvious choice.^^63^^\n\nAmong the various ethanol sources, sugarcane is by far the most efficient in both land and energy use. The ethanol yield of sugarcane per acre is roughly 650 gallons, whereas for corn in the United States it is 350 gallons, scarcely half as much. The net energy yield of 8 for sugarcane offers an overwhelming advantage over that of the 1.5 for corn.^^64^^\n\nThe palm oil yield of over 500 gallons of biodiesel per acre compares very favorably with 56 gallons per acre for soybeans. The downside of sugarcane and palm oil as feedstocks is that both are grown in tropical and subtropical regions, which means their production will likely be expanded by clearing tropical forests.^^65^^\n\nThe most efficient automotive fuel option appears to the gas-electric hybrid with a plug-in capacity and wind energy as the principal fuel. Since nearly all the basic food commodities can be converted into automotive fuel, either ethanol or biodiesel, there is a risk that rising oil prices will stimulate massive investments in biofuels production, using food staples as the feedstock. This could set up direct competition between affluent motorists and low-income food consumers for the same foodstuffs, including wheat, rice, corn, soybeans, and sugarcane. Avoiding this potential competition between supermarkets and service stations for the same food commodities will depend on governments establishing policies to protect food consumers.\n\nIn a world facing disruptive climate change, each country will need to fashion its own carbon reduction strategy in light of its unique complement of renewable sources of energy and its most promising potentials for raising energy efficiency. Yet, many technologies for cutting carbon emissions, such as energy-efficient household appliances and gas-electric hybrid vehicles, are common to all societies.\n\nAmong countries, Iceland may be the only one that currently has a strategy to phase out the use of fossil fuels, including oil, entirely. Currently it heats 85 percent of all its buildings, residential and commercial, with geothermal energy. In addition, 82 percent of its electricity comes from hydropower, with most of the remaining electricity geothermally generated. It is now using its cheap hydroelectricity to electrolyze water and produce hydrogen. With its first hydrogen station in operation in Reykjavik, the country is turning to fuel-cell-powered buses. Next it plans to convert its automobiles to fuel cells and then eventually to do the same with its fishing fleet, which lies at the heart of its economy.\n\nThe biggest single gain in carbon emission reductions could come in the U.S. automotive sector where, as described earlier, the potential exists for cutting gasoline use by a staggering 85 percent. This model applied worldwide could help the world adjust to the coming decline in oil production.^^67^^\n\nFor the United States, its rich endowment of low-cost wind energy suggests that wind will likely emerge as the centerpiece of the new energy economy. It can supply electricity for heating, cooling, cooking, powering automobiles, and even producing steel, using energy-efficient electric arc furnaces for steel smelting. The United States, which gets 7 percent of its electricity from existing hydroelectric facilities, also has a substantial geothermal potential in the western states and an enormous solar cell potential throughout the country.\n\nGermany plans to cut its carbon emissions dramatically by continuously raising energy efficiency and harnessing renewable energy resources, with an emphasis on wind. By 2050, Germany plans to reduce overall energy use by 37 percent as it uses the latest technologies to raise energy efficiency. Of the remaining 63 percent, 45 percent will come from renewables. This means a cut of 65 percent in overall carbon emissions. Germany will rely heavily on wind and solar cells for electricity generation and solar thermal panels for water and space heating.^^69^^\n\nIndonesia's energy future lies in its vast resources of geothermal energy. With more than enough geothermal energy to satisfy all its electricity needs, Indonesia can also develop its abundance of solar and wind resources and use electricity to fuel hybrid vehicles. With 11 percent of its electricity coming from hydro, Indonesia has a wide range of renewable energy sources.^^70^^\n\nFor Spain, bathed in sunlight year-round, solar cells and solar panels will figure prominently in supplying electricity, heating, and cooling. Spain is also moving fast to develop its rich endowment of wind energy.\n\nBrazil is unique in that self-sufficiency in automotive fuel in the form of sugarcane-based ethanol could be only a few years away. Along with a generous supply of hydropower, wind and solar cells will also supply electricity. Solar panels will heat water. Brazil could be one of the first large countries to substantially phase out fossil fuels.^^72^^\n\nFor China, hydropower already supplies 15 percent of its electricity, but the big potential lies with wind. China could easily double its current electricity generation from wind alone. Like the United States, a combination of gas-electric hybrids with a second storage battery and a plug-in capacity and a heavy investment in harnessing its abundant wind resources can minimize the use of gasoline and reduce dependence on coal.^^73^^\n\nIn the United Kingdom, wind-generated electricity, primarily from offshore wind farms, holds enormous potential. This, combined with wave power (of which it has an abundance) and solar panels for water heating, can meet much of the country's energy needs.^^74^^\n\nFor Argentina, where hydropower already supplies 42 percent of electricity, wind could easily supply the remainder. Its large Patagonian region has some of the richest wind resources found anywhere. Argentina also has the potential for solar electricity and solar panels.^^75^^\n\nDuring the last century, the world became increasingly dependent on a small handful of countries in the Middle East for its energy. During this century, the world is turning to local energy resources. The last century saw the globalization of the energy economy, while today we are seeing its localization. Whereas "one size fit all" in the last century, in the twenty-first century each country will fashion an energy strategy that fits its own renewable energy resources and its potential for raising energy efficiency.\n\nFor countries everywhere, particularly developing countries, the economic good news in the energy transition is that it is much more labor-intensive than the use of fossil fuels. Even though Germany is still early in the energy transition, renewable energy industries already employ more workers than the long-standing fossil fuel and nuclear industries. In a world where unemployment is widespread, this is welcome news indeed.^^76^^\n\nFurthermore, in contrast to investments in oil and gas fields and coal mines, where depletion and abandonment were inevitable, the new energy sources are inexhaustible. While wind turbines, solar cells, and solar thermal panels will all need repair and occasional replacement, the initial investment can last indefinitely. This well will not go dry.\n\n[[10.7 - Additional Resources]]\n\n[[10.8 - Notes]]\n\n[[11 - Designing Sustainable Cities]]

As I was being driven through Tel Aviv from my hotel to a conference center a few years ago, I could not help but note the overwhelming presence of cars and parking lots. Tel Aviv, expanding from a small settlement a half-century ago to a city of some 3 million today, evolved during the automobile era. It occurred to me that the ratio of parks to parking lots may be the best single indicator of the livability of a city - an indication of whether the city is designed for people or for cars.^^1^^\n\nThe world's cities are in trouble. In Mexico City, Tehran, Bangkok, Shanghai, and hundreds of other cities, the quality of daily life is deteriorating. Breathing the air in some cities is equivalent to smoking two packs of cigarettes per day. In the United States, the number of hours commuters spend going nowhere sitting in traffic-congested streets and highways climbs higher each year, raising frustration levels.^^2^^\n\nIn response to these conditions, we are seeing the emergence of a new urbanism. One of the most remarkable modern urban transformations has occurred in Bogot√°, Colombia, where Enrique Pe√Ďalosa served as Mayor for three years, beginning in 1998. When he took office he did not ask how life could be improved for the 30 percent who owned cars; he wanted to know what could be done for the 70 percent - the majority - who did not own cars.^^3^^\n\nPe√Ďalosa realized that a city that is a pleasant environment for children and the elderly would work for everyone. In just a few years, he transformed the quality of urban life with his vision of a city designed for people. Under his leadership, the city banned the parking of cars on sidewalks, created or renovated 1,200 parks, introduced a highly successful bus-based rapid transit system, built hundreds of kilometers of bicycle paths and pedestrian streets, reduced rush hour traffic by 40 percent, planted 100,000 trees, and involved local citizens directly in the improvement of their neighborhoods. In doing this, he created a sense of civic pride among the city's 8 million residents, making the streets of Bogot√° in this strife-torn country safer than those in Washington, D.C.^^4^^\n\nEnrique Pe√Ďalosa observes that "high quality public pedestrian space in general and parks in particular are evidence of a true democracy at work." He further observes: "Parks and public space are also important to a democratic society because they are the only places where people meet as equals. ... In a city, parks are as essential to the physical and emotional health of a city as the water supply." He notes this is not obvious from most city budgets, where parks are deemed a luxury. By contrast, "roads, the public space for cars, receive infinitely more resources and less budget cuts than parks, the public space for children. Why," he asks, "are the public spaces for cars deemed more important than the public spaces for children?"^^5^^\n\nIn espousing this new urban philosophy, Pe√Ďalosa is not alone. The reform he initiated in Bogot√° is being carried on by his successor, Antanas Mockus. Now government planners everywhere are experimenting, seeking ways to design cities for people not cars. Cars promise mobility, and they provide it in a largely rural setting. But in an urbanizing world there is an inherent conflict between the automobile and the city. After a point, as their numbers multiply, automobiles provide not mobility but immobility.\n\nSome cities in industrial and developing countries alike are dramatically increasing urban mobility by moving away from the car. Jaime Lerner, the former mayor of Curitiba, Brazil, was one of the first to design and adopt an alternative transportation system, one that does not mimic those in the West but that is inexpensive and commuter-friendly. Since 1974 Curitiba's transportation system has been totally restructured. Although one third of the people own cars, these play a minor role in urban transport. Busing, biking, and walking totally dominate, with two thirds of all trips in the city by bus. The city's population has doubled since 1974, but its car traffic has declined by a remarkable 30 percent.^^7^^\n\nAside from the growth of population itself, urbanization is the dominant demographic trend of our time. In 1900, 150 million people lived in cities. By 2000, it was 2.9 billion people, a 19-fold increase. By 2007 more than half of us will live in cities - making us, for the first time, an urban species.^^8^^\n\nIn 1900 there were only a handful of cities with a million people. Today 408 cities have at least that many inhabitants. And there are 20 megacities with 10 million or more residents. Tokyo's population of 35 million exceeds that of Canada. Mexico City's population of 19 million is nearly equal to that of Australia. New York, S√£o Paulo, Mumbai (formerly Bombay), Delhi, Calcutta, Buenos Aires, and Shanghai follow close behind.^^9^^\n\n[[11.1 - The Ecology of Cities]]\n\n[[11.2 - Redesigning Urban Transport]]\n\n[[11.3 - Farming in the City]]\n\n[[11.4 - Reducing Urban Water Use]]\n\n[[11.5 - The Challenge of Urban Slums]]\n\n[[11.6 - Cities for People]]\n\n[[11.7 - Additional Resources]]\n\n[[11.8 - Notes]]\n\n[[12 - Building a New Economy]]\n\n----\nDownload pdf version of Chapter 11\n\n 21pp. (150 Kb)
Cities require a concentration of food, water, energy, and materials that nature cannot provide. Concentrating these masses of materials and then dispersing them in the form of garbage, sewage, and as pollutants in air and water is challenging city managers everywhere.\n\nMost of today's cities are not healthy places to live. Urban air everywhere is polluted. Typically centered on the automobile and no longer bicycle- or pedestrian-friendly, cities deprive people of needed exercise, creating an imbalance between caloric intake and caloric expenditures. As a result, obesity is reaching epidemic proportions in cities in developing as well as industrial countries. With more than 1 billion people overweight worldwide, epidemiologists now see this as a public health threat of historic proportions - a growing source of heart disease, high blood pressure, diabetes, and a higher incidence of several forms of cancer.^^10^^\n\nThe evolution of modern cities is tied to advances in transport, initially for ships and trains, but it was the internal combustion engine combined with cheap oil that provided the mobility of people and freight that fueled the phenomenal urban growth of the twentieth century. As the world urbanized, energy use climbed.\n\nEarly cities relied on food and water from the surrounding countryside, but today cities often depend on distant sources even for such basic amenities. Los Angeles, for example, draws much of its water supply from the Colorado River, some 970 kilometers (600 miles) away. Mexico City's burgeoning population, living at 3,000 meters, must now depend on the costly pumping of water from 150 kilometers away and must lift it a kilometer or more to augment its inadequate water supplies. Beijing is planning to draw water from the Yangtze River basin nearly 1,500 kilometers away.\n\nFood comes from even greater distances, as is illustrated by Tokyo. While Tokyo still depends for its rice on the highly productive farmers in Japan, with their land carefully protected by government policy, its wheat comes largely from the Great Plains of North America and from Australia. Its corn supply comes largely from the U.S. Midwest. Soybeans come from the U.S. Midwest and the Brazilian //cerrado//.\n\nThe oil that provides much of the energy to move resources into and out of cities itself often comes from distant oil fields. Rising oil prices will affect cities, but they will affect even more the suburbs that many cities have spawned.\n\nIt is widely assumed that urbanization will continue. But this is not necessarily so. The growing scarcity of water and the high cost of the energy invested in transporting water over long distances may itself begin to constrain urban growth. For example, some 400 cities in China are already facing a chronic shortage of water.^^13^^\n\nAgainst this backdrop, Richard Register, author of //Ecocities: Building Cities in Balance with Nature//, says it is time to fundamentally rethink the design of cities. He agrees with Pe√Ďalosa that cities should be designed for people, not for cars. He goes even further, talking about pedestrian cities - communities designed so that people do not need cars because they can walk to most of the places they need to go or take public transportation.^^14^^\n\nRegister also says that a city should be seen as a functioning system not in terms of its parts but in terms of its whole. He makes a convincing case that cities should be integrated into local ecosystems rather than imposed on them.^^15^^\n\nHe describes with pride an after-the-fact integration into the local ecosystem of San Luis Obispo, a California town of 50,000 north of Los Angeles: "[It] has a beautiful creek restoration project with several streets and through-building passageways lined with shops that connect to the town's main commercial street, and people love it. Before closing a street, turning a small parking lot into a park, restoring the creek and making the main street easily accessible to the 'nature' corridor, that is, the creek, the downtown had a 40% vacancy rate in the storefronts; and now it has zero. Of course it's popular. You sit at your restaurant by the creek ... where fresh breezes rustle the trees in a world undisturbed by car noise and blazing exhaust." San Luis Obispo is surrounded by both natural and agricultural landscapes.^^16^^\n\nFor Register, the design of the city and its buildings become a part of the local landscape, capitalizing on the local ecology. For example, buildings are designed to be heated and cooled by nature as much as possible. Later in this chapter we discuss how cities can largely live on recycled water that is cleaned and used again and again. The "flush and forget" water system will become too costly for many water-short cities in a world after oil. Urban food production, particularly fresh fruits and vegetables, will expand in vacant lots and on rooftops as oil prices rise.^^17^^\n\nIn the years ahead, urbanization could slow or even be reversed. In a world of land, water, and energy scarcity, the value of each resource may increase substantially, shifting the terms of trade between the countryside and cities. Ever since the beginning of the Industrial Revolution, the terms of trade have favored cities because they control capital and technology, the scarce resources. But if land and water become the scarcest resources, then those in rural areas who control them may sometimes have the upper hand. With a new economy based on renewable energy, a disproportionate share of that energy, particularly wind energy and biofuels, will come from nearby rural areas.^^18^^\n\nBeyond resource shortages, the evolution of the Internet, which is changing how we think about distance and mobility, could also affect urbanization. Among other things, the potential for telecommuting may reduce the advantages of living in a city. Internet commerce, offering more options than any shopping mall, may also lessen the role of urban shopping centers as sources of a wide variety of goods and services.\n\n[[11.2 - Redesigning Urban Transport]]\n\n[[11.3 - Farming in the City]]\n\n[[11.4 - Reducing Urban Water Use]]\n\n[[11.5 - The Challenge of Urban Slums]]\n\n[[11.6 - Cities for People]]\n\n[[11.7 - Additional Resources]]\n\n[[11.8 - Notes]]\n\n[[12 - Building a New Economy]]
Urban transport systems based on a combination of rail lines, bus lines, bicycle pathways, and pedestrian walkways offer the best of all possible worlds in providing mobility, low-cost transportation, and a healthy urban environment. Megacities regularly turn to underground rail systems to provide mobility. Whether it is these rail systems, light-rail surface systems, or both depends in part on city size and geography. For cities of intermediate size, light rail is often an attractive option.\n\nA rail system provides the foundation for a city's transportation system. Rails are geographically fixed, providing a permanent means of transportation that people can count on. Once in place, the nodes on such a system become the obvious places to concentrate office buildings, high-rise apartment buildings, and shops.\n\nAs noted earlier, some of the most innovative public transportation systems, those that move huge numbers of people from cars into buses, have been developed in Curitiba and Bogotá. The success of Bogotá's bus rapid transit (BRT) system TransMilenio, which relies on special express lanes to move people quickly through the city, is being replicated not only in six other Colombian cities, but in cities elsewhere too: Beijing, Mexico City, São Paulo, Seoul, Taipei, and Quito. Several more cities in Africa and China are also planning BRT systems. Even industrial-country cities, such as Ottawa and - much to everyone's delight - Los Angeles, are now considering BRT systems.^^19^^\n\nMany cities are reducing traffic congestion and air pollution by charging cars to enter the city. Singapore, long a leader in urban transport innovation, has imposed a tax on all roads leading into the city center. Electronic sensors identify each car, and then debit the owner's credit card. This system has reduced the number of automobiles in Singapore, providing its residents with both more mobility and cleaner air than in most other cities.^^20^^\n\nSingapore has been joined by London and by several Norwegian cities, including Oslo, Bergen, and Trondheim. In London - where the average speed of an automobile a few years ago was about the same as that of a horse-drawn carriage a century ago - a congestion tax was adopted in early 2003. The £5 charge on all motorists driving into the center city between 7\n\na.m. and 6:30 p.m. immediately reduced the number of vehicles, permitting traffic to flow more freely while cutting pollution and noise.^^21^^\n\nDuring the first year after the new tax was introduced, the number of people using buses to travel into the central city climbed by 38 percent. Since the congestion charge, the daily flow of cars into central London has been reduced by 65,000-70,000, a drop of 18 percent, while delays have dropped by 30 percent. The number of bicycles and mopeds has increased by 17 percent, and vehicle speeds on key thoroughfares have increased by 21 percent, from 8.7 to 10.6 miles per hour.^^22^^\n\nContrary to the fear about falling profits, 65 percent of businesses in London's inner city have not noticed any effect on their bottom line. A substantial majority of business owners think the reduced vehicle flow has had a positive effect on the city's image. A similar tax is now being considered in Cardiff for adoption within the near future. Other cites considering the measure include Stockholm, São Paulo, San Francisco, Milan, and Barcelona. French officials are looking at a congestion charge to deal with the suffocating air pollution in Paris. This highly successful use of taxes to restructure urban transport systems is discussed in terms of restructuring the overall economy in Chapter 12.^^23^^\n\nThe bicycle, a form of personal transportation, has many attractions. It alleviates congestion, lowers air pollution, reduces obesity, increases physical fitness, does not emit climate-disrupting carbon dioxide, and has a price within reach for the billions of people who cannot afford an automobile. Bicycles increase mobility while reducing congestion and the area of land paved over. Six bicycles can typically fit into the road space used by one car. For parking, the advantage is even greater, with 20 bicycles occupying the space required to park a car.^^24^^\n\nThe bicycle is not only a flexible means of transportation, it is an ideal way of restoring a balance between caloric intake and expenditure. The opportunity to exercise is valuable in its own right. Regular exercise of the sort provided by cycling to work reduces cardiovascular disease, osteoporosis, and arthritis and strengthens the immune system. Millions of people pay a monthly fee to use a fitness center, which they often drive to, where they ride stationary bikes, trying to achieve the same benefits.\n\nFew methods of reducing carbon emissions are as effective as substituting the bicycle for the automobile on short trips. A bicycle is a marvel of engineering efficiency, one where an investment in 13 kilograms (28 pounds) of metal and rubber boosts the efficiency of individual mobility by a factor of three. On my bike I estimate that I get easily 7 miles (11 kilometers) per potato. An automobile, which requires 1-2 tons of material to transport even one person, is extraordinarily inefficient in comparison.\n\nThe capacity of the bicycle to provide mobility for low-income populations was dramatically demonstrated in China. In 1976, China produced 6 million bicycles. After the reforms in 1978 that led to rapid economic growth, rising incomes, and a market economy in which people could exercise their preferences, annual bicycle production started climbing, eventually soaring over 40 million in 1988. Once the market was largely saturated, production dropped somewhat and remained between 30 million and 40 million a year through the 1990s. Since 1999, production has taken off once again, rising to 79 million bicycles in 2004. The vast surge to 545 million bicycle owners in China since 1978 provided the greatest increase in human mobility in history. Bicycles took over city streets and rural roads. Although China's 7 million passenger cars are getting a lot of attention, especially in the large cities, it is the bicycle that provides personal mobility.\n\nMany cities are turning to bicycles for numerous uses. In the United States, more than 80 percent of police departments serving populations of 50,000-249,999 and 96 percent of those serving more than 250,000 residents now have routine patrols by bicycle. Officers on bikes are more productive in cities partly because they are more mobile and can reach the scene of an accident or crime more quickly and more quietly than officers in cars. They typically make 50 percent more arrests per day than officers in squad cars. For fiscally sensitive officials, the cost of operating a bicycle is trivial compared with that of a police car.^^26^^\n\nUrban bicycle messenger services are common in the world's larger cities. Bicycles deliver small parcels in cities more quickly than motor vehicles can and at a much lower cost. As the information economy unfolds and as e-commerce expands, the need for quick, reliable, urban delivery services is escalating. For many competitive Internet marketing firms, quick delivery wins customers. In a city like New York, this means bicycle delivery. An estimated 300 bicycle messenger firms are operating in New York City, competing for $700 million worth of business annually. In large cities, the bicycle is becoming an integral part of the support system for e-commerce.^^27^^\n\nThe key to realizing the potential of the bicycle is to create a bicycle-friendly transport system. This means providing both bicycle trails and designated street lanes for bicycles. These should be designed to serve both commuters and those biking for recreation. In addition, bicycle use is enhanced by the provision of parking facilities and showers at workplaces. Among the industrial-country leaders in designing bicycle-friendly transport systems are the Dutch, the Danes, and the Germans.^^28^^\n\nThe Netherlands, the unquestioned leader among industrial countries in encouraging bicycle use, has incorporated a vision of the role of bicycles into a Bicycle Master Plan. In addition to creating bike lanes and trails in all its cities, the system also often gives cyclists the advantage over motorists in right-of-ways and at traffic lights. Some traffic signals permit cyclists to move out before cars. Roughly 30 percent of all urban trips in the Netherlands are on bicycle. This compares with 1 percent in the United States.^^29^^\n\nSpain, one of the latest countries to climb on the bicycle bandwagon, began converting abandoned railway lines into recreational paths in 1993. The 52 new "greenways" include 1,300 kilometers of bicycle trails throughout the country.\n\nWithin the Netherlands a nongovernmental group called Interface for Cycling Expertise (I-ce) has been formed to share the Dutch experience in designing a modern transport system that prominently features bicycles. It is working with other groups in Brazil, Colombia, Ghana, India, Kenya, South Africa, Sri Lanka, Tanzania, and Uganda to facilitate bicycle use. Roelof Wittink, head of I-ce, observes, "If you plan only for cars then drivers will feel like the King of the Road. This reinforces the attitude that the bicycle is backward and used only by the poor. But if you plan for bicycles it changes the public attitude."^^31^^\n\nBoth the Netherlands and Japan have made a concerted effort to integrate bicycles and rail commuter services by providing bicycle parking at rail stations, making it easier for cyclists to commute by train. In Japan, the use of bicycles for commuting to rail transportation has reached the point where some stations have invested in vertical, multi-level parking garages for bicycles, much as is often done for automobiles.^^32^^\n\nThe combination of rail and bicycle, and particularly their integration into a single, overall transport system, makes a city eminently more livable than one that relies almost exclusively on private automobiles. Noise, pollution, congestion, and frustration are all lessened. We and the earth are both healthier.\n\n[[11.3 - Farming in the City]]\n\n[[11.4 - Reducing Urban Water Use]]\n\n[[11.5 - The Challenge of Urban Slums]]\n\n[[11.6 - Cities for People]]\n\n[[11.7 - Additional Resources]]\n\n[[11.8 - Notes]]\n\n[[12 - Building a New Economy]]
While attending a conference on the outskirts of Stockholm in the fall of 1974, I walked past a community garden near a high-rise apartment building. It was an idyllic Indian summer afternoon, with many people tending gardens a short walk from their residences. More than 30 years later I can still recall the setting because of the aura of contentment surrounding those working in their gardens. Nearly all were elderly; they were absorbed in producing not only vegetables, but in some cases flowers as well. I remember thinking, "This is the mark of a civilized society."\n\nIn June 2005, the U.N. Food and Agriculture Organization (FAO) reported that urban and peri-urban farms - those within or immediately adjacent to a city - supply food to some 700 million urban residents worldwide. These are mostly small plots - vacant lots, yards, even rooftops.^^33^^\n\nWithin and near the city of Dar es Salaam, capital of Tanzania, there are some 650 hectares of land producing vegetables. This land supplies not only the city's fresh produce but a livelihood for 4,000 farmers who intensively farm their small plots year-round. On the far side of the continent, an FAO project has urban residents in Dakar, Senegal, producing up to 30 kilograms of tomatoes per square meter each year with continuous cropping in rooftop gardens.^^34^^\n\nIn Hanoi, 80 percent of the fresh vegetables come from farms in and immediately adjacent to the city. These urban farms also produce 50 percent of the pork and the poultry consumed in the city. Half of the city's freshwater fish are produced by enterprising urban fish farmers. Some 40 percent of the egg supply is produced within the city or in its shadow. Urban farmers ingeniously recycle human and livestock waste to nourish plants and to fertilize fish ponds.^^35^^\n\nPeople living in wetlands in the region of East Calcutta in India manage wastewater fish ponds that cover nearly 3,500 hectares. The city's sewage water is kept in ponds and moved through various stages so the bacteria can break down the organic waste. This, in turn, supports the rapid growth of algae that supply food for the various local strains of herbivorous fish. This system provides a steady supply of fish for the city, fish that are consistently of better quality than any entering the Calcutta market.^^36^^\n\nThe magazine //Urban Agriculture// describes how Shanghai has in effect created a nutrient recycling zone around the city. In order to have enough land to recycle the city's night soil, the boundary was extended to include 300,000 hectares of surrounding farmland. This land supplies 60 percent of this megacity's vegetables. Half of Shanghai's pork and poultry and 90 percent of its milk and eggs come from the extended city and the immediately surrounding region.^^37^^\n\nIn Caracas, Venezuela, a government-sponsored FAO-assist-ed project has created 4,000 microgardens of one square meter each in the city's barrios, many of them located within a few steps of family kitchens. As soon as one crop is mature, it is harvested and immediately replaced with new seedlings. Each square meter, continuously cropped, can produce 330 heads of lettuce, 18 kilograms of tomatoes, or 16 kilograms of cabbage per year.^^38^^\n\nVenezuela's goal is to have 100,000 microgardens in the country's urban areas and 1,000 hectares of urban compost-based gardens nationwide. Leonardo Gil Mora, vice minister of integrated rural development, points out that "in the barrios as in Venezuela in general, people are the most important thing we have. Through urban agriculture, we hope to increase the poor's self-confidence, and so increase their participation in society."^^39^^\n\nThere is a long tradition of community gardens in European cities. As a visitor flies into Paris, numerous community gardens can be seen on the outskirts of the city. These small plots produce not only high-quality food but a sense of well-being and community.\n\nAs a result of a national campaign in Cuba to expand urban farming after the loss of Soviet support more than a decade ago, Havana now produces half of the vegetables its residents consume. The city-state of Singapore has 10,000 urban farmers who produce four fifths of the poultry and a fourth of all the vegetables eaten there. A 2003 //Urban Agriculture// study reports that 14 percent of London's 7.6 million residents produce some of their own food. For Vancouver, Canada's largest west coast city, the comparable figure is an impressive 44 percent.^^40^^\n\nIn the U.S. city of Philadelphia, community gardeners were asked why they gardened. Some 20 percent did it for recreational reasons, 19 percent said it improved their mental health, and 17 percent their physical health. Another 14 percent did it because they wanted the higher-quality fresh produce that a garden could provide, 10 percent did it for spiritual reasons, and 7 percent said it was mostly economic - cost and convenience. Urban gardens are social gathering places that engender a sense of community. In addition, those who garden three to four times a week get the same physical benefits as people who engage in moderate walking or bicycling.^^41^^\n\nIn some countries, such as the United States, there is a huge unrealized potential for urban gardening. A survey indicated that Chicago has 70,000 vacant lots, and Philadelphia, 31,000. Nationwide, vacant lots in cities would total in the hundreds of thousands. The Urban Agriculture report summarizes why urban agriculture is so desirable. It has "a regenerative effect ... when vacant lots are transformed from eyesores - weedy, trash-ridden dangerous gathering places - into bountiful, beautiful, and safe gardens that feed people's bodies and souls."^^42^^\n\nGiven the near inevitable rise in future oil prices, the economic benefits of expanding urban agriculture, even in affluent societies, will become much more obvious. Aside from supplying more fresh produce, it will help millions discover the social benefits and the psychological well-being that urban gardening can bring.\n\n[[11.4 - Reducing Urban Water Use]]\n\n[[11.5 - The Challenge of Urban Slums]]\n\n[[11.6 - Cities for People]]\n\n[[11.7 - Additional Resources]]\n\n[[11.8 - Notes]]\n\n[[12 - Building a New Economy]]
The one-time use of water to disperse human and industrial wastes is an outmoded practice, made obsolete by new technologies and water shortages. Water enters the city, is contaminated with human and industrial wastes, and leaves the city dangerously polluted. Toxic industrial wastes discharged into rivers and lakes or into wells also permeate aquifers, making water - both surface and underground - unsafe for drinking. And their toxic wastes are destroying marine ecosystems, including local fisheries. The time has come to manage waste without discharging it into the local environment, allowing water to be recycled indefinitely and reducing both urban and industrial demand dramatically.\n\nThe current engineering concept for dealing with human waste is to use vast quantities of water to wash it away, preferably into a sewer system where it will be treated before being discharged into the local river. The "flush and forget" system is water-intensive, it disrupts the nutrient cycle, most of humanity cannot afford it, and it is a major source of disease in developing countries.\n\nAs water scarcity spreads, the viability of water-based sewage systems will diminish. Water-based sewage systems take nutrients originating in the soil and typically dump them into rivers, lakes, or the sea. Not only are the nutrients lost from agriculture, but the nutrient overload has led to the death of many rivers and to the formation of some 146 dead zones in ocean coastal regions. Sewer systems that dump untreated sewage into rivers and streams are a major source of disease and death.^^43^^\n\nSunita Narain of the Centre for Science and Environment in India argues convincingly that a water-based disposal system with sewage treatment facilities is neither environmentally nor economically viable for India. She notes that an Indian family of five, producing 250 liters of excrement in a year and using a water flush toilet, requires 150,000 liters of water to wash away its wastes.^^44^^\n\nAs currently designed, India's sewer system is actually a pathogen-dispersal system. It takes a small quantity of contaminated material and uses it to make vast quantities of water unfit for human use, often simply discharging it into nearby rivers or streams. Narain says both "our rivers and our children are dying." India's government, like that of many other developing countries, is hopelessly chasing the goal of universal water-based sewage systems and sewage treatment facilities - unable to close the huge gap between services needed and provided, but unwilling to admit that it is not an economically viable option. Narain concludes that the "flush and forget" approach is not working.^^45^^\n\nThis dispersal of pathogens is a huge public health challenge. Worldwide, poor sanitation and personal hygiene claim\n\n2.7 million lives per year, second only to the 5.9 million claimed by hunger and malnutrition.^^46^^\n\nFortunately, there is a low-cost alternative: the composting toilet. This is a simple, waterless, odorless toilet linked to a small compost facility. Table waste can also be incorporated into the composter. The dry composting converts human fecal material into a soil-like humus, which is essentially odorless and is scarcely 10 percent of the original volume. These compost facilities need to be emptied every year or so, depending on design and size. Vendors periodically collect the humus and can market it as a soil supplement, thus ensuring that the nutrients and organic matter return to the soil, reducing the need for fertilizer.^^47^^\n\nThis technology reduces residential water use, thus cutting water bills and lowering the energy needed to pump and purify water. As a bonus, it also reduces garbage flow if table waste is incorporated, eliminates the sewage water disposal problem, and restores the nutrient cycle. The U.S. Environmental Protection Agency now lists several brands of dry toilets approved for use. Pioneered in Sweden, these toilets work well under the widely varying conditions where they are now used, including Swedish apartment buildings, U.S. private residences, and Chinese villages.^^48^^\n\nAt the household level, water can be saved by using appliances that are more water-efficient, including showerheads, flush toilets, dishwashers, and clothes washers. Some countries are adopting water efficiency standards and labeling for appliances, much as has been done for energy efficiency. When water costs rise, as they inevitably will, investments in composting toilets and more water-efficient household appliances will become increasingly attractive to individual homeowners.\n\nFor cities, the most effective single step to raise water productivity is to adopt a comprehensive water treatment/recycling system, reusing the same water continuously. With this system, only a small percentage of water is lost to evaporation each time it cycles through. Given the technologies that are available today, it is quite possible to recycle urban water supplies comprehensively, largely removing cities as a claimant on scarce water resources.\n\nSome cities faced with shrinking water supplies and rising water costs are beginning to recycle their water supplies. Singapore, for example, which buys its water from Malaysia at an ever higher price, is beginning to recycle water, reducing the amount it imports. For some cities, the continuous recycling of water may become a condition of their survival.^^49^^\n\nIndividual industries facing the same water-related issues as cities are beginning to move away from the use of water to disperse industrial waste. Some companies segregate effluent streams, treating each individually with the appropriate chemicals and membrane filtration, preparing the water for reuse. Peter Gleick, senior author and editor of the biannual report //The World's Water,// writes: "Indeed, some industries, such as paper and pulp, industrial laundries, and metal finishing, are beginning to develop 'closed-loop' systems where all the waste water is reused internally, with only small amounts of fresh water needed to make up for water incorporated into the product or lost in evaporation." Industries are moving faster than cities, but the technologies they are developing can also be used in urban water recycling.^^50^^\n\nSaving water in cities depends primarily on two household appliances: toilets and showers, which together account for over half of indoor use. Whereas traditional flush toilets used 6 gallons (or 22.7 liters) per flush, the legal U.S. maximum for new toilets is 1.6 gallons (6 liters). An Australian-produced toilet with a dual-flush two-button technology uses only 1 gallon for a liquid waste flush and 1.6 gallons for a solid waste flush. Shifting from a showerhead flowing at 5 gallons per minute to a 2.5 gallons-per-minute model cuts water use nearly in half. With washing machines, a horizontal axis design developed in Europe uses 40 percent less than the traditional top-loading U.S. models. In addition, this European model now being marketed internationally also uses less energy.\n\nThe existing water-based waste disposal economy is not viable. There are too many households, factories, and feedlots to simply try and wash waste away on our crowded planet. To do so is ecologically mindless and outdated - an approach that belongs to an age when there were many fewer people and far less economic activity.\n\n[[11.5 - The Challenge of Urban Slums]]\n\n[[11.6 - Cities for People]]\n\n[[11.7 - Additional Resources]]\n\n[[11.8 - Notes]]\n\n[[12 - Building a New Economy]]
Between 2000 and 2050, there is little population growth projected for the industrial countries or for the rural developing world. Thus nearly all of the projected world population growth of some 3 billion people by 2050 will be added to the cities of developing countries, much of it in squatter settlements.^^52^^\n\nSquatter settlements - whether they are //favelas// in Brazil, //barriadas// in Peru, or //gecekondu// in Turkey - typically consist of an urban residential area inhabited by very poor people who do not have any land. They simply "squat" on vacant land, either private or public.^^53^^\n\nLife in these settlements is characterized by grossly inadequate housing and a lack of access to urban services. As Hari Srinivas, coordinator of the Global Development Research Center, writes, these rural-urban migrants undertake the "drastic option of illegally occupying a vacant piece of land to build a rudimentary shelter" simply because it is their only option. They are often treated if not by apathy then by antipathy by government agencies, who view them as invaders and trouble. Some see squatter settlements as a social "evil," something that needs to be eradicated.^^54^^\n\nUrban slums include not only squatter settlements but also severely rundown older parts of cities, which are also overcrowded and often lacking in rudimentary urban services, such as sewage disposal.\n\nOne of the best ways to make rural/urban migration manageable is to improve conditions in the countryside. This means not only providing basic social services, such as basic health care and education for children, as outlined in Chapter 7, but also encouraging industrial investment in small towns throughout the country rather than just in prime cities, such as Mexico City or Bangkok. Such policies will slow the flow into cities to a more orderly pace.\n\nThe evolution of cities in developing countries is often shaped by the unplanned nature of squatter settlements. Letting squatters settle wherever they can - on steep slopes, on river floodplains, or in other high-risk areas - makes it difficult to provide basic services such as transport, water, and sewerage. Curitiba, on the cutting edge of the new urbanism, has designated tracts of land for squatter settlements. By setting aside these planned tracts, the process can at least be structured in a way that is consistent with the official development plan of the city.\n\nAmong the simplest services that can be provided in a squatter settlement are community composting toilets. Beyond these, taps that provide safe running water at intervals throughout the squatter settlement can go a long way to control the spread of disease in overcrowded settlements. Regular bus service can enable workers living in the settlements to travel to their place of work. If the Curitiba approach is widely followed, parks and other commons areas can be incorporated into the community from the beginning.\n\nSome political elites simply want to bulldoze squatter settlements away, but this treats the symptoms of urban poverty, not the cause. People who lose what little they have been able to invest in housing are not richer as a result of the demolition, but poorer, as is the city itself. The preferred option by far is in situ upgrading of housing. The key to this is providing security of tenure to the squatters and small loans, enabling them to make incremental improvements over time.^^56^^\n\nUpgrading slums depends on local governments that respond to them rather than ignoring them. Progress in eradicating poverty and creating stable, progressive communities depends on establishing constructive links with governments. In some cases, government-supported micro-credit lending facilities can help not only establish a link between the city government and the squatter communities but offer hope to the residents.^^57^^\n\nAlthough political leaders might hope that these settlements will be driven away or demolished, the reality is that they will likely expand over the next several decades. The challenge is to integrate them into urban life in a humane way that provides hope through the potential for upgrading. The inevitable alternative is mounting resentment, spreading social friction, and violence.\n\n[[11.6 - Cities for People]]\n\n[[11.7 - Additional Resources]]\n\n[[11.8 - Notes]]\n\n[[12 - Building a New Economy]]
As the new century begins, it is becoming evident to urban dwellers, whether in industrial or developing countries, that there is an inherent conflict between the automobile and the city. Urban air pollution, often from automobiles, claims millions of lives. Congestion also takes a direct economic toll in rising costs in time and gasoline.\n\nAnother cost of cities that are devoted to cars is a psychological one, a deprivation of contact with the natural world - an "asphalt complex." There is a growing body of evidence that there is an innate human need for contact with nature. Both ecologists and psychologists have been aware of this for some time. Ecologists, led by Harvard University biologist E.O. Wilson, have formulated the "biophilia hypothesis," which argues that those who are deprived of contact with nature suffer psychologically and that this deprivation leads to a measurable decline in well-being.^^58^^\n\nMeanwhile psychologists have coined their own term - ecopsychology - in which they make the same argument. Theodore Roszak, a leader in this field, cites a study that documents humans' dependence on nature by looking at the rate of recovery of patients in a hospital in Pennsylvania. Those whose rooms overlooked gardens with grass, trees, flowers, and birds recovered from illnesses more quickly than those who were in rooms overlooking the parking lot.^^59^^\n\nOne of the arguments for community gardens is that in addition to providing food, they also provide greenery and a sense of community. Working with soil and watching things grow has a therapeutic effect.\n\nThroughout the modern era, budget allocations for transportation in most countries - and in the United States, in particular - have been heavily biased toward the construction and maintenance of highways and streets. Creating more livable cities and the mobility that people desire depends on reallocating budgets to emphasize the development of rail- or bus-based public transport and bicycle support facilities.\n\nThe exciting news is that there are signs of change, daily indications of an interest in redesigning cities for people, not for cars. One encouraging trend comes from the United States. Rising public transit ridership nationwide of 2.1 percent a year since 1996 indicates that people are gradually abandoning their cars for buses, subways, and light rail. Sharp rises in gasoline prices in 2005 are encouraging still more commuters to abandon their cars and take the bus or subway or get on a bicycle.^^60^^\n\nMayors and city planners the world over are beginning to rethink the role of the car in urban transportation systems. A group of eminent scientists in China challenged Beijing's decision to promote an automobile-centered transportation system. They noted a simple fact: China does not have enough land to accommodate the automobile and to feed its people. What is true for China is also true for India and dozens of other densely populated developing countries.^^61^^\n\nSome cities are far better at planning their growth than others. They plan transport systems that provide mobility, clean air, and exercise - a sharp contrast to cities that offer congestion, unhealthy air, and little opportunity for exercise. When 95 percent of a city's workers depend on the automobile for commuting, as in Atlanta, Georgia, the city is in trouble. By contrast, in Amsterdam only 40 percent of workers commute by car; 35 percent commute by bike or walk, while 25 percent use public transit. Copenhagen's commuting patterns are almost identical to Amsterdam's. In Paris, just under half of commuters rely on cars. Even though these European cities are older, often with narrow streets, they have far less congestion than Atlanta.^^62^^\n\nNot surprisingly, car-dependent cities have more congestion and less mobility than those that offer a wider range of commuting options. The very vehicle whose great promise was personal mobility is in fact virtually immobilizing entire urban populations, making it difficult for rich and poor alike to move about.\n\nExisting long-term transportation strategies in many developing countries assume that everyone will one day be able to own a car. Unfortunately, given the constraints of land available for cars, not to mention those imposed by oil reserves, this is simply not realistic. These countries will provide more mobility if they support public transportation and the bicycle.\n\nIf developing-country governments continue to invest most of the public resources available for transportation in support of the automobile, they will end up with a system built for the small fraction of their people who own cars. Recognition now that most people will never own automobiles can lead to a fundamental reorientation of transport planning and investment.\n\nThere are many ways to restructure the transportation system so that it satisfies the needs of all people, not just the affluent, so that it provides mobility, not immobility, and so that it improves health rather than damaging it. One is to eliminate the subsidies, often indirect, that many employers provide for parking. For example, parking subsidies in the United States that are worth an estimated $85 billion a year obviously encourage people to drive to work.^^63^^\n\nIn 1992, California mandated that employers match parking subsidies with cash that can be used by the recipient either to pay public transport fares or to buy a bicycle. In firms where data were collected, this shift in policy reduced automobile use by some 17 percent. At the national level, a provision was incorporated into the 1998 Transportation Equity Act of the 21st Century to change the tax code so that those who used public transit or vanpools would enjoy the same tax-exempt subsidies as those who received free parking. What societies should be striving for is not parking subsidies, but parking taxes - taxes that begin to reflect the cost to the community of traffic congestion and the deteriorating quality of life as cities are taken over by cars and parking lots.^^64^^\n\nScores of cities are declaring car-free areas, among them Stockholm, Vienna, Prague, and Rome. Paris enjoys a total ban on cars along stretches of the Seine River on Sundays and holidays and is looking to make much of the central city traffic-free starting in 2012.^^65^^\n\nIn addition to ensuring that subways are functional and affordable, the idea of making them attractive, even cultural centers, is gaining support. In Moscow, with works of art in the stations, the subway system is justifiably referred to as Russia's crown jewel. In Washington, D.C., Union Station, which links the city's subway system with intercity train lines, is an architectural delight. Since its restoration was completed in 1988, it has become a social gathering place, with shops, conference rooms, and a rich array of restaurants.\n\nOne of the more innovative steps to encourage the use of public transportation comes from State College, a small town in central Pennsylvania that is home to Pennsylvania State University. To reduce traffic congestion on campus and to address the lack of sufficient parking, Penn State decided in 1999 that it would provide $1 million to the bus-based local transit system in exchange for unlimited free rides for its students, faculty, and staff. As a result, bus ridership in State College jumped by 240 percent in one year, requiring the transit company to invest heavily in new buses to accommodate the additional passengers. This initiative by the university has created a far more pleasant, attractive campus - an asset in recruiting both students and faculty.\n\nAs the new century begins, the world is reconsidering the urban role of automobiles in one of the most fundamental shifts in transportation thinking in a century. The challenge is to redesign communities, making public transportation the centerpiece of urban transport and augmenting it with sidewalks, jogging trails, and bikeways. This also means replacing parking lots with parks, playgrounds, and playing fields. We can design an urban lifestyle that systematically restores health by incorporating exercise into daily routines while reducing air pollution and obesity.\n\n[[11.7 - Additional Resources]]\n\n[[11.8 - Notes]]\n\n[[12 - Building a New Economy]]

In Chapter 1 we concluded that the western economic model - the fossil-fuel-based, automobile-centered, throwaway economy - was not viable for the world. Instead, the new economy will be powered by renewable sources of energy, will have a more diverse transport system - relying more on rail, buses, and bicycles and less on cars - and will recycle materials comprehensively.\n\nWe can describe this new economy in some detail. The question is how to get from here to there quickly enough to avoid economic decline and collapse. In our favor, we do have some assets that earlier civilizations did not, including archeological records, more advanced scientific knowledge, and, most important, a sense of how to use economic policy to achieve social goals.\n\nThe key to building a global economy that can sustain economic progress is the creation of an honest market, one that tells the ecological truth. The market is an incredible institution, allocating resources with an efficiency that no central planning body can match. It easily balances supply and demand, and it sets prices that readily reflect both scarcity and abundance.\n\nThe market does, however, have some fundamental weaknesses. It does not incorporate into prices the indirect costs of providing goods or services into prices, it does not value nature's services properly, and it does not respect the sustainable-yield thresholds of natural systems. It also favors the near term over the long term, showing little concern for future generations.\n\nThroughout most of recorded history, the indirect costs of economic activity were so small that they were rarely an issue and, even then, only at the local level. But with the seven-fold global economic expansion since 1950, the failure to address these market shortcomings and the irrational economic distortions they create could be fatal.^^1^^\n\nAs noted in Chapter 1, accounting systems that do not tell the truth can be costly. Faulty corporate accounting systems that leave costs off the books have driven some of the world's largest corporations into bankruptcy. Unfortunately, our faulty global economic accounting system has potentially far more serious consequences. Our modern economic prosperity is achieved in part by running up ecological deficits, costs that do not show up on the books, but costs that someone will eventually pay.\n\nOnce we calculate the indirect costs of a product or service, we can incorporate them into market prices in the form of a tax, offsetting them with income tax reductions. If we can get the market to tell the truth, then we can avoid being blindsided by faulty accounting systems that lead to bankruptcy. As √ėystein Dahle, former Vice President of Exxon for Norway and the North Sea, has pointed out: "Socialism collapsed because it did not allow the market to tell the economic truth. Capitalism may collapse because it does not allow the market to tell the ecological truth."^^2^^\n\n[[12.1 - Shifting Taxes]]\n\n[[12.2 - Shifting Subsidies]]\n\n[[12.3 - Ecolabeling: Voting with Our Wallets]]\n\n[[12.4 - A New Materials Economy]]\n\n[[12.5 - New Industries, New Jobs]]\n\n[[12.6 - The Environmental Revolution]]\n\n[[12.7 - Additional Resources]]\n\n[[12.8 - Notes]]\n\n[[13 - Plan B: Building a New Future]]\n\n----\nDownload pdf version of Chapter 12\n\n 24pp. (93 Kb)
The need for tax shifting - lowering income taxes while raising levies on environmentally destructive activities - in order to get the market to tell the truth has been widely endorsed by economists. For example, a tax on coal that incorporated the increased health care costs associated with breathing polluted air, the costs of damage from acid rain, and the costs of climate disruption would encourage investment in renewable sources of energy such as wind or geothermal. With this concept in hand, it is a short step to tax shifting. A number of countries in Western Europe are already shifting taxes in a process known there as environmental tax reform, to achieve the environmental goals outlined in preceding chapters.^^3^^\n\nAmong the various environmentally damaging activities taxed in Europe are carbon emissions, the generation of garbage (so-called landfill taxes), and the excessive number of cars in cities. A four-year plan adopted in Germany in 1999 systematically shifted taxes from labor to energy. By 2001, this plan had lowered fuel use by 5 percent. It had also accelerated growth in the renewable energy sector, creating some 45,400 jobs by 2003 in the wind industry alone, a number that is projected to rise to 103,000 by 2010.^^4^^\n\nIn 2001, Sweden launched a bold new 10-year environmental tax shift designed to convert 30 billion kroner ($3.9 billion) of taxes on income to taxes on environmentally destructive activities. Much of this shift of $1,100 per household is levied on road transport, including substantial hikes in vehicle and fuel taxes. Electricity is also picking up part of the shift. As of 2005, Sweden is running slightly ahead of its 10-year tax-shifting plan, making it the world leader in environmental tax reform.^^5^^\n\nAmong the other European countries with strong tax reform efforts are Spain, Italy, Norway, the United Kingdom, and France. There are isolated cases elsewhere. A number of countries, including Malaysia, Thailand, and Turkey, have used a tax on lead emissions to eliminate lead as an additive in gasoline. The United States imposed a stiff tax on chlorofluorocarbons to phase them out in accordance with the Montreal Protocol of 1987 and its subsequent updates. At the municipal level, when Victoria, the capital of British Columbia, adopted a trash tax of $1.20 per bag of garbage in 1992, it reduced its daily trash flow 18 percent within one year.^^6^^\n\nCities that are being suffocated by cars are using stiff entrance taxes to reduce congestion. First adopted by Singapore some two decades ago, this tax was later introduced by Oslo, Melbourne, and, most recently, London. The London tax of ¬£5, or nearly $9, first enacted in February 2002 by Mayor Ken Livingstone, was raised to ¬£8, more than $14, in July 2005. The resulting revenue will be invested in improving the bus network, which carries 2 million passengers a day. The goal of this congestion tax is a total restructuring of the London transport system to reduce congestion, air pollution, and carbon emissions and to increase mobility.\n\nWhile London and other cities are taxing cars that enter the central city, others are simply imposing a tax on automobile ownership. In Denmark, the tax on the purchase of a new car is larger than the price of the car itself. A new $25,000 car costs the buyer more than $50,000! In 2000, partial rebates were introduced for energy-efficient vehicles. Other governments are moving in this direction. //New York Times// reporter Howard French writes that Shanghai, which is being suffocated by automobiles, "has raised the fees for car registrations every year since 2000, doubling over that time to about $4,600 per vehicle - more than twice the city's per capita income."^^8^^\n\nFor some products where the costs to society are large and obvious, pressure is mounting to impose taxes. By far the most dramatic example of this was the agreement negotiated between the tobacco industry and all the state governments in the United States. After numerous state governments launched litigation to force tobacco companies to reimburse them for the Medicare costs of treating smoking-related illnesses, the industry decided to negotiate a package reimbursement, agreeing in November 1998 to pay the 50 state governments some $251 billion - nearly $1,000 for every person in the United States. This landmark agreement was, in effect, a retroactive tax on cigarettes smoked in the past, one designed to cover indirect costs. To pay this enormous bill, companies boosted cigarette prices, further discouraging smoking.^^9^^\n\nA study by the Centers for Disease Control and Prevention (CDC) in the United States calculated the social costs of smoking cigarettes at $7.18 per pack. This not only justifies raising taxes on cigarettes, which claim 4.9 million lives per year worldwide, but it also provides guidelines for how much to raise them. In 2002, a year in which state governments faced fiscal deficits, 21 states in the United States raised cigarette taxes. Perhaps the biggest jump came in New York City, where smokers paid an additional 39¬Ę in state tax and $1.42 in city tax - a total increase of $1.81 per pack. Since a 10-percent price increase typically reduces smoking by 4 percent, the health benefits of this tax increase should be substantial.^^10^^\n\nIf the cost to society of smoking a pack of cigarettes is $7.18,\n\nhow much is the cost to society of burning a gallon of gasoline? Fortunately, as noted in Chapter 1, the International Center for Technology Assessment has done a detailed analysis, entitled "The Real Price of Gasoline." The group calculates several indirect costs, including oil industry tax breaks, oil supply protection costs, oil industry subsidies, and health care costs of treating auto exhaust-related respiratory illnesses. The total of these indirect costs centers around $9 per gallon, somewhat higher than the social cost of smoking a pack of cigarettes. Add this external or social cost to the roughly $2 per gallon average price of gasoline in the United States in early 2005, and gas would cost $11 a gallon. These costs are real. Someone bears them. Now that these costs have been calculated, they can be used to set tax rates on gasoline, just as the CDC analysis is being used to raise taxes on cigarettes.^^11^^\n\nAsia's two leading economies - Japan and China - are now considering the adoption of carbon taxes. For the last few years, many members of the Japanese Diet have wanted to launch an environmental tax shift, but industry has opposed a carbon tax. China, which is experiencing near-record explosive growth in energy use and carbon emissions, is working on an environmental tax restructuring that will discourage fossil fuel use. Wang Fengchun, an official with the National People's Congress, says, "Taxation is the most powerful tool available in a market economy in directing a consumer's buying habits. It is superior to government regulations." If Chinese policymakers can engineer an environmental tax reform, it will be a landmark development not only for China but for the world.^^12^^\n\nEnvironmental tax shifting usually brings a double dividend. In reducing taxes on income - in effect, taxes on labor - labor becomes less costly, creating additional jobs while protecting the environment. This was the principal motivation in the German four-year shift of taxes from income to energy. By reducing the air pollution from smokestacks and tailpipes, the incidence of respiratory illnesses, such as asthma and emphysema, is reduced - and thus overall health care costs are as well.^^13^^\n\nWith forests, ecologists can calculate the values of services that trees provide. Once these are determined, they can be incorporated into the price of trees as a stumpage tax of the sort that Bulgaria and Lithuania have adopted. Anyone wishing to cut a tree would have to pay a tax equal to the value of the services provided by that tree, such as flood control. The market for lumber would then be telling the ecological truth. The effect of this is to reduce tree cutting and to encourage wood reuse and paper recycling.^^14^^\n\nTax shifting also helps countries gain the lead in producing new equipment, such as new energy technologies or those used for pollution control. For example, the Danish government's tax incentives for wind-generated electricity have enabled Denmark, a country of only 5 million people, to become the world's leading manufacturer of wind turbines.^^15^^\n\nSome 2,500 economists, including eight Nobel Prize winners in economics, have endorsed the concept of tax shifts. Harvard economics professor N. Gregory Mankiw wrote in //Fortune// magazine: "Cutting income taxes while increasing gasoline taxes would lead to more rapid economic growth, less traffic congestion, safer roads, and reduced risk of global warming - all without jeopardizing long-term fiscal solvency. This may be the closest thing to a free lunch that economics has to offer."^^16^^\n\n//The Economist// strongly endorses environmental tax shifting: "On environmental grounds, never mind energy security, America taxes gasoline too lightly. Better than a one-off increase, a politically more feasible idea, and desirable in its own terms, would be a long-term plan to shift taxes from incomes to emissions of carbon." In Europe and the United States, polls indicate that at least 70 percent of voters support environmental tax reform once it is explained to them.^^17^^\n\nTradable permits are sometimes a sensible alternative to environmental taxes. Both are economic instruments that can be used to reach environmental goals. The principal difference between them is that with permits, governments set the amount of a given activity that is allowed, such as the harvest from a fishery, and let the market set the price of the permits as they are auctioned off. With environmental taxes, in contrast, the price of the environmentally destructive activity is set by government in the tax rate, and the market determines the amount of the activity that will occur at that price. Both economic instruments can be used to discourage environmentally irresponsible behavior.^^18^^\n\nThe decision of when to use which instrument is not always clearcut. Governments have much more experience with environmental taxes than with tradable permits. It is also clear that such taxes work under a wide range of conditions. Still, permits have been used successfully in widely differing situations, ranging from restricting the catch in an Australian fishery to reducing sulfur emissions in the United States.\n\nFor example, concerned about the overfishing of its lobster fishery, the government of Australia estimated the sustainable yield of lobsters and then issued permits totaling that amount. Fishers could then bid for these permits. In effect, the government decided how many lobsters could be taken each year and let the market decide how much the permits were worth. Since the permit trading system was adopted in 1986, the fishery has stabilized and appears to be operating on a sustainable basis.^^19^^\n\nPerhaps the most ambitious effort to date to use tradable permits was the U.S. effort to reduce sulfur emissions from power plants by half from 1990 to 2000. The goal was reached in 1995, well ahead of schedule and at a minimal cost. One of the weaknesses of tradable permits is that in some communities emissions might not be reduced at all.^^20^^\n\nAlthough tradable permits are popular in the business community, permits are administratively more complicated and not as well understood as taxes. Edwin Clark, former senior economist with the White House Council on Environmental Quality, observes that tradable permits "require establishing complex regulatory frameworks, defining the permits, establishing the rules for trades, and preventing people from acting without permits." In contrast to restructuring taxes, something with which there is wide familiarity, tradable permits are a concept not widely understood by the public, making it more difficult to generate broad public support.^^21^^\n\n[[12.2 - Shifting Subsidies]]\n\n[[12.3 - Ecolabeling: Voting with Our Wallets]]\n\n[[12.4 - A New Materials Economy]]\n\n[[12.5 - New Industries, New Jobs]]\n\n[[12.6 - The Environmental Revolution]]\n\n[[12.7 - Additional Resources]]\n\n[[12.8 - Notes]]\n\n[[13 - Plan B: Building a New Future]]
Each year the world's taxpayers provide an estimated $700 billion of subsidies for environmentally destructive activities, such as fossil fuel burning, overpumping aquifers, clearcutting forests, and overfishing. An Earth Council study, //Subsidizing Unsustainable Development//, observes that "there is something unbelievable about the world spending hundreds of billions of dollars annually to subsidize its own destruction."^^22^^\n\nIran provides a classic example of extreme subsidies when it prices oil for internal use at one tenth the world price, strongly encouraging car ownership and gas consumption. The World Bank reports that if this $3.6-billion annual subsidy were phased out, it would reduce Iran's carbon emissions by a staggering 49 percent. It would also strengthen the economy by freeing up public revenues for investment in the country's economic development. Iran is not alone. The Bank reports that removing energy subsidies would reduce carbon emissions in Venezuela by 26 percent, in Russia by 17 percent, in India by 14 percent, and in Indonesia by 11 percent.^^23^^\n\nSome countries are eliminating or reducing these climate-disrupting subsidies. Belgium, France, and Japan have phased out all subsidies for coal. Germany reduced its coal subsidy from $5.4 billion in 1989 to $2.8 billion in 2002, meanwhile lowering its coal use by 46 percent. It plans to phase out this support entirely by 2010. China cut its coal subsidy from $750 million in 1993 to $240 million in 1995. More recently, it has imposed a tax on high-sulfur coals.^^24^^\n\nA study by the U.K. Green Party, "Aviation's Economic Downside," describes the extent of subsidies currently given to the U.K. airline industry. The giveaway begins with $17 billion in tax breaks, including a total exemption from the federal tax. External or indirect costs that are not paid, such as treating illness from breathing the air polluted by planes, the costs of climate change, and so forth, adds nearly $7 billion to the tab. The subsidy in the United Kingdom totals $391 per resident. This is also an inherently regressive tax policy simply because a substantial share of the U.K. population cannot afford to fly very often if at all, yet they help subsidize this high-cost mode of transportation for their more affluent compatriots.^^25^^\n\nWhile some leading industrial countries have been reducing subsidies to fossil fuels - notably coal, the most climate disrupting of all fuels - the United States has been increasing its support for the fossil fuel and nuclear industries. A Green Scissors report from 2002, a study supported by a coalition of environmental groups, calculated that over the past 10 years subsidies for the energy industry totaled $33 billion. Of that, the oil and gas industry got $26 billion, coal $3 billion, and nuclear $4 billion. At a time when there is a need to conserve oil resources, U.S. taxpayers are subsidizing their depletion.^^26^^\n\nThe environmental tax shifting just described reduces taxes on wages and encourages investment in such activities as wind electric generation and recycling, thus simultaneously boosting employment and lessening environmental destruction. Eliminating environmentally destructive subsidies reduces both the burden on taxpayers and the destructive activities themselves.\n\nSubsidies are not inherently bad. Many technologies and industries were born of government subsidies. Jet aircraft developed with military R&D expenditures led to modern commercial airliners. The Internet was the result of publicly funded links among computers in government laboratories and research institutes. And the combination of the federal tax deduction and a robust state tax deduction in California gave birth to the modern wind power industry.\n\nBut just as there is a need for tax shifting, there is also a need for subsidy shifting. A world facing the prospect of economically disruptive climate change, for example, can no longer justify subsidies to expand the burning of coal and oil. Shifting these subsidies to the development of climate-benign energy sources such as wind, solar, biomass, and geothermal power is the key to stabilizing the earth's climate. Shifting subsidies from road construction to rail construction could increase mobility in many situations while reducing carbon emissions.\n\nIn a troubled world economy facing fiscal deficits at all levels of government, exploiting these tax and subsidy shifts with their double and triple dividends can help balance the books and save the economy's environmental support systems. Tax and subsidy shifting promise both gains in economic efficiency and reductions in environmental destruction, a win-win situation.\n\n[[12.3 - Ecolabeling: Voting with Our Wallets]]\n\n[[12.4 - A New Materials Economy]]\n\n[[12.5 - New Industries, New Jobs]]\n\n[[12.6 - The Environmental Revolution]]\n\n[[12.7 - Additional Resources]]\n\n[[12.8 - Notes]]\n\n[[13 - Plan B: Building a New Future]]
Yet another instrument for environmental restructuring of the economy is ecolabeling. Labeling products that are produced with environmentally sound practices lets consumers vote with their wallets. Ecolabeling is now used to enable consumers to identify energy-efficient household appliances, forest products from sustainably managed forests, fishery products from sustainably managed fisheries, and "green" electricity from renewable sources.\n\nAmong these ecolabels are those awarded by the Marine Stewardship Council (MSC) for seafood. In March 2000, the MSC launched its fisheries certification program when it approved the Western Australia Rock Lobster fishery. Also earning approval that day was the West Thames Herring fishery. In September 2000, the Alaska salmon fishery became the first American fishery to be certified. Among the key players in the seafood processing and retail sectors supporting the MSC initiative were European-based Unilever, Youngs-Bluecrest, and Sainsbury's.^^28^^\n\nTo be certified, a fishery must demonstrate that it is being managed sustainably. Specifically, according to the MSC: "First, the fishery must be conducted in a way that does not take more fish than can be replenished naturally or [that] kills other species through harmful fishing practices. Secondly, the fishery must operate in a manner that ensures the health and diversity of the marine ecosystem on which it depends. Finally, the fishery must respect local, national, and international laws and regulations for responsible and sustainable fishing." By mid-2005 there were over 46 certified fisheries worldwide supplying some 2 million tons of seafood.^^29^^\n\nThe MSC's counterpart for forest products is the Forest Stewardship Council (FSC), which was founded in 1993 by the World Wide Fund for Nature (WWF) and other groups. It provides information on forest management practices within the forest products industry. Some of the world's forests are managed to sustain a steady harvest in perpetuity; others are clearcut, decimated overnight in the quest for quick profits. The FSC issues labels only for products from the former, whether it be lumber sold at a hardware store, furniture in a furniture store, or paper in a stationery store.^^30^^\n\nHeadquartered in Oaxaca, Mexico, the FSC accredits national organizations that verify that forests are being sustainably managed. In addition to this on-the-ground monitoring, the accredited organizations must also be able to trace the raw product through the various stages of processing to the consumer. The FSC sets the standards and provides the FSC label, the stamp of approval, but the actual work is done by national organizations.^^31^^\n\nThe FSC has established nine principles that must be satisfied if forests are to qualify for its label. The central requirement is that the forest be managed in a way that ensures that its yield can be sustained indefinitely. This means careful selective cutting, in effect mimicking nature's management of a forest by removing the more mature, older trees over time.^^32^^\n\nThe FSC label provides consumers with the information they need to support responsible forestry through their purchases of forest products. By identifying timber companies and retailers that are participating in the certification program, socially minded investors also have the information they need for responsible investing.\n\nIn March 1996, the first certified wood products were introduced into the United Kingdom. Since then, the certification process has grown worldwide. As of August 2005, some 57 million hectares of forests in 65 countries had been certified under the auspices of the FSC.^^33^^\n\nTo support this certification program, forest and trade networks have been set up in some 35 countries, including Austria, Brazil, Canada, France, Germany, the Nordic countries, Russia, Spain, Switzerland, the United Kingdom, and the United States. These networks are part of the vast support group of companies that adhere to the FSC standards in their marketing. The world's three largest wood buyers - Home Depot, Lowe's, and Ikea - all preferentially buy FSC-certified wood.^^34^^\n\nIn June 2001, the Natural Resources Ministry in Moscow announced that it was introducing national mandatory certification of wood. Although a small portion of its timber harvest was already certified, buyers' discrimination against the rest of the harvest costs Russia $1 billion in export revenues. The ministry estimates that its uncertified wood sells for 20-30 percent less than certified wood from competing countries.^^35^^\n\nAnother commodity that is getting an environmental label is electricity. In the United States, many state utility commissions are requiring utilities to offer consumers a green power option. This is defined as power from renewable sources other than hydroelectric, and it includes wind power, solar cells, solar thermal energy, geothermal energy, and biomass. Utilities simply enclose a return card with the monthly bill, giving consumers the option of checking a box if they would prefer to get green power. The offer specifies the additional cost of the green power, which typically is from 3 to 15 percent.^^36^^\n\nUtility officials are often surprised by how many consumers sign up for green power. Many are apparently prepared to pay more for their electricity in order to help stabilize the climate for future generations. Local governments, including, for example, those in Santa Monica, Oakland, and Santa Barbara in California, have signed up to use green power exclusively. This includes the power they use for municipal buildings as well as that required to operate various municipal services, such as street lights and traffic signals. Other city and state governments committed to purchasing a portion of their electricity from green sources include Chicago, Portland, New Jersey, and New York.^^37^^\n\nMany corporations are signing up as well. Johnson & Johnson, Whole Foods Market, and Staples all rank among the top 25 green power purchasers, according to the Environmental Protection Agency's Green Power Partnership. Literally scores of companies in California and Texas are subscribing.^^38^^\n\nThe net effect of these growing numbers of green power proponents is a tidal wave of demand that is forcing many utilities to scramble for an adequate supply of green electricity. One reason wind farms are springing up in so many states is that this is one of the fastest ways to bring new green power online. While green power marketing is now quite advanced in the United States, it is now also well established in Japan, where the rapidly growing purchases of green power threatened to outrun the supply in 2004, forcing utilities to quickly invest in more wind turbines.^^39^^\n\nOther types of ecolabeling include the efficiency labels put on household appliances that achieve a certain electricity efficiency standard. These have been in effect in many countries since the energy crisis of the late 1970s. There are also green labels provided by environmental or governmental groups at the national level. Among the better-known environmental seal of approval programs are Germany's Blue Angel, Canada's Environmental Choice, and the U.S. Environmental Protection Agency's Energy Star.^^40^^\n\n[[12.4 - A New Materials Economy]]\n\n[[12.5 - New Industries, New Jobs]]\n\n[[12.6 - The Environmental Revolution]]\n\n[[12.7 - Additional Resources]]\n\n[[12.8 - Notes]]\n\n[[13 - Plan B: Building a New Future]]
In nature, one-way linear flows do not long survive. Nor, by extension, can they long survive in the expanding economy that is a part of the earth's ecosystem. The challenge is to redesign the materials economy so that it is compatible with nature.\n\nThe throwaway economy that has been evolving over the last half-century is an aberration, now itself headed for the junk heap of history.\n\nThe potential for reducing materials use has been examined over the last decade in three specific studies. The first - //Factor Four//, by Ernst von Weizs√§cker, an environmentalist and leader in the German Bundestag - argued that modern industrial economies could function very effectively with a level of virgin raw material use only one fourth that of today. This was followed a few years later by the Factor Ten Institute organized in France under the leadership of Friedrich Schmidt-Bleek. Its research concludes that resource productivity can be raised by a factor of 10, which is well within the reach of existing technology and management given the appropriate policy incentives.^^41^^\n\nIn 2002, American architect William McDonough and German chemist Michael Braungart teamed up to coauthor a book entitled //Cradle to Cradle: Remaking the Way We Make Things//. Waste and pollution are to be avoided at any cost. "Pollution," says McDonough, "is a symbol of design failure."^^42^^\n\nOne of the keys to reducing materials use is recycling steel, the use of which dwarfs that of all other metals combined. Steel use is dominated by the automobile, household appliance, and construction industries. Among steel-based products in the United States, automobiles are the most highly recycled. Cars today are simply too valuable to be left to rust in out-of-the-way junk-yards.^^43^^\n\nThe recycling rate for household appliances is estimated at 90 percent. For steel cans, the U.S. recycling rate in 2003 of 60 percent can be traced in part to municipal recycling campaigns launched in the late 1980s.^^44^^\n\nIn the United States, roughly 71 percent of all steel produced in 2003 was from scrap, leaving 29 percent to be produced from virgin ore. Steel recycling started climbing more than a generation ago with the advent of the electric arc furnace, a method of producing steel from scrap that uses only one third the energy of that produced from virgin ore. And since it does not require any mining, it completely eliminates one source of environmental disruption. In the United States, Italy, and Spain, electric arc furnaces used for recycling now account for half or more of all steel production.^^45^^\n\nIt is easier for mature industrial economies with stable populations to get most of their steel from recycled scrap, simply because the amount of steel embedded in the economy is essentially fixed. The number of household appliances, the fleet of automobiles, and the stock of buildings is increasing little or not at all. For countries in the early stages of industrialization, however, the creation of infrastructure - whether factories, bridges, high-rise buildings, or transportation, including automobiles, buses, and rail cars - leaves little steel for recycling.\n\nIn the new economy, electric arc steel minimills that efficiently convert scrap steel into finished steel will largely replace iron mines. Advanced industrial economies will come to rely primarily on the stock of materials already in the economy rather than on virgin raw materials. For metals such as steel and aluminum, the losses through use will be minimal. With the appropriate policies, metal can be used and reused indefinitely.\n\nIn recent years, the construction industry has begun deconstructing old buildings, breaking them down into their component parts so they can be recycled and reused. For example, when PNC Financial Services in Pittsburgh took down a seven-story downtown building, the principal products were 2,500 tons of concrete, 350 tons of steel, 9 tons of aluminum, and foam ceiling tiles. The concrete was pulverized and used to fill in the site, which is to become a park. The steel and aluminum were recycled. And the ceiling tiles went back to the manufacturer to be recycled. This recycling saved some $200,000 in dump fees. By deconstructing a building instead of simply demolishing it, most of the material in it can be recycled.^^46^^\n\nGermany and, more recently, Japan are requiring that products such as automobiles, household appliances, and office equipment be designed so that they can be easily disassembled and their component parts recycled. In May 2001, the Japanese Diet enacted a tough appliance recycling law, one that prohibits discarding household appliances, such as washing machines, televisions, or air conditioners. With consumers bearing the cost of disassembling appliances in the form of a disposal fee to recycling firms, which can come to $60 for a refrigerator or $35 for a washing machine, the pressure to design appliances so they can be more easily and cheaply disassembled is strong.^^47^^\n\nWith computers becoming obsolete every few years as technology advances, the need to be able to quickly disassemble and recycle them is a paramount challenge in building an eco-economy.\n\nIn addition to measures that encourage the recycling of materials are those that encourage the reuse of products such as beverage containers. Finland, for example, has banned the use of one-way soft drink containers. Canada's Prince Edward Island has adopted a similar ban on all nonrefillable beverage containers. The result in both cases is a sharply reduced flow of garbage to landfills.^^48^^\n\nA refillable glass bottle used over and over requires about 10 percent as much energy per use as an aluminum can that is recycled. Cleaning, sterilizing, and relabeling a used bottle requires little energy, but recycling cans made from aluminum, which has a melting point of 660 degrees Celsius (1,220 degrees Fahrenheit), is an energy-intensive process. Banning nonrefillables is a win-win-win option - cutting material and energy use, garbage flow, and air and water pollution.^^49^^\n\nThere are also transport fuel savings, since the containers are simply back-hauled to the original bottling plants or breweries. If nonrefillable containers are used, whether glass or aluminum, and they are recycled, then they must be transported to a manufacturing facility where they can be melted down, refashioned into containers, and transported back to the bottling plant or brewery.\n\nEven more fundamental than the design of products is the redesign of manufacturing processes to eliminate the discharge of pollutants entirely. Many of today's manufacturing processes evolved at a time when the economy was much smaller and when the volume of pollutants was not overwhelming the ecosystem. More and more companies are now realizing that this cannot continue and some, such as Dupont, have adopted zero emissions as a goal.^^50^^\n\nAnother way to reduce waste is to systematically cluster factories so that the waste from one process can be used as the raw material for another. NEC, the large Japanese electronics firm, is one of the first multinationals to adopt this approach for its various production facilities. In effect, industrial parks are being designed, both by corporations and governments, specifically to combine factories that have usable waste products. Now in industry, as in nature, one firm's waste becomes another's sustenance.^^51^^\n\nGovernment procurement policies can be used to dramatically boost recycling. For example, when the Clinton administration issued an Executive Order in 1993 requiring that all government-purchased paper contain 20 percent or more post-consumer waste by 1995 (increasing to 25 percent by 2000), it created a strong incentive for paper manufacturers to incorporate wastepaper in their manufacturing process. Since the U.S. government is the world's largest paper buyer, this provided a burgeoning market for recycled paper.^^52^^\n\nNew technologies that are less material-dependent also reduce materials use. Cellular phones, which rely on widely dispersed towers or on satellites for signal transmission, now totally dominate telephone use in developing countries, thus sparing them investment in the millions of miles of copper wires that the industrial countries made.^^53^^\n\nOne industry whose value to society is being questioned by the environmental community is the bottled water industry. The World Wide Fund for Nature, an organization with 5.2 million members, released a study in 2001 urging consumers in industrial countries to forgo bottled water, observing that it was no safer or healthier than tap water, even though it can cost 1,000 times as much.^^54^^\n\nWWF notes that in the United States and Europe there are more standards regulating the quality of tap water than of bottled water. Although clever marketing in industrial countries has convinced many consumers that bottled water is healthier, the WWF study could not find any support for this claim. For those living where water is unsafe, as in some Third World cities, it is far cheaper to boil or filter water than to buy it in bottles.^^55^^\n\nPhasing out the use of bottled water would eliminate the need for billions of plastic bottles and the fleets of trucks that haul and distribute the water. This in turn would eliminate the traffic congestion, air pollution, and rising carbon dioxide levels from operating the trucks.^^56^^\n\nA brief review of the environmental effects of gold mining raises doubts about whether the industry is a net benefit to society. In addition to the extensive release of mercury and cyanide into the environment, annual gold production of 2,500 tons requires the processing of 750 million tons of ore - second only to the 2.5 billion tons of ore processed to produce 1 billion tons of raw steel.^^57^^\n\nOver 80 percent of all the gold mined each year is used to produce jewelry that is often worn as a status symbol, a way of displaying wealth by a tiny affluent minority of the world's people. Birsel Lemke, a widely respected Turkish environmentalist, questions the future of gold mining, wondering whether it is worth turning large areas into what she calls "a lunar landscape." She is not against gold per se, but against the deadly chemicals - cyanide and mercury - that are released in processing the gold ore.^^58^^\n\nTo get an honest market price for gold means imposing a tax on it that would cover the cost of cleaning up the mercury and cyanide pollution from mining plus the costs of landscape restoration in mining regions. Such a tax, which would enable the price of this precious metal to reflect its full cost to society, would likely raise its price severalfold.\n\nAnother option for reducing the use of raw materials would be to eliminate subsidies that encourage their use. Nowhere are these greater than in the aluminum industry. For example, a study by the Australia Institute reports that smelters in Australia buy electricity at an astoundingly low subsidized rate of 0.7-1.4¬Ę per kilowatt-hour, while other industries pay 2.6-3.1¬Ę. Without this huge subsidy, we might not have nonrefillable aluminum beverage containers. This subsidy to aluminum indirectly subsidizes both airlines and automobiles, thus encouraging travel, an energy-intensive activity.\n\nThe most pervasive policy initiative to dematerialize the economy is the proposed tax on the burning of fossil fuels, a tax that would reflect the full cost to society of mining coal and pumping oil, of the air pollution associated with their use, and of climate disruption. A carbon tax will lead to a more realistic energy price, one that will permeate the energy-intensive materials economy and reduce materials use.\n\nThe challenge in building an eco-economy materials sector is to ensure that the market is sending honest signals. In the words of Ernst von Weizs√§cker, "The challenge is to get the market to tell the //ecological// truth." To help the market to tell the truth, we need not only a carbon tax, but also a landfill tax so that those generating garbage pay the full cost of getting rid of it.^^60^^\n\n[[12.5 - New Industries, New Jobs]]\n\n[[12.6 - The Environmental Revolution]]\n\n[[12.7 - Additional Resources]]\n\n[[12.8 - Notes]]\n\n[[13 - Plan B: Building a New Future]]
Describing the eco-economy is obviously speculative, but less so than it might seem simply because its broad outlines are defined by the principles of ecology. The specific trends and shifts described here are not projections of what will happen, though the term "will" is often used for the sake of efficiency. No one knows if these shifts "will" in fact occur, but it will take something similar to this if we are to build an eco-economy.\n\nBuilding a new economy involves phasing out old industries, restructuring existing ones, and creating new ones. For example, coal use is being phased out, replaced by efficiency gains in many countries, but also by natural gas, as in the United Kingdom, and by wind power, as in Denmark and Germany.\n\nThe world automobile industry faces a modest restructuring as it shifts from the gasoline-powered internal combustion engine to the gas-electric hybrid, the diesel-electric hybrid, or the high-efficiency diesel that is so popular in Europe. This will require both a retooling of engine plants and the retraining of automotive engineers and automobile mechanics.\n\nThe new economy will also bring major new industries, ones that either do not yet exist or are just beginning. Wind electricity generation is one such industry, incorporating three subsidiary industries: turbine manufacturing, installation, and maintenance. Now in its embryonic stage, this promises to become the foundation of the new energy economy. Millions of turbines soon will be converting wind into cheap electricity, becoming part of the landscape, generating income and jobs in rural communities throughout the world.\n\nAs wind power emerges as a mainstream low-cost source of electricity, it will spawn another industry - hydrogen production. Once wind turbines are in wide use, there will be a large, unused capacity during the night when electricity use drops. With this essentially free electricity, turbine owners can turn on the hydrogen generators, converting the wind power into hydrogen. This can then be used to run power plants now fueled with natural gas, as gas becomes too costly or is no longer available. The wind turbine will replace the coal mine, the oil well, and the gas field.\n\nAmong the many changes in the world food economy will be the continuing shift to fish farming. Aquaculture, the fastest growing subsector of the world food economy, has expanded at 9 percent a year since 1990. The farming of fish, particularly omnivorous species such as carp, catfish, and tilapia, is likely to continue expanding rapidly simply because these fish convert grain into animal protein so efficiently. With this aquacultural growth comes the need for a rapidly expanding aquafeed industry, one where feeds are formulated by fish nutritionists, much as they are for the poultry industry today.\n\nBicycle manufacturing and servicing is a growth industry. As recently as 1965, world production of cars and bikes was essentially the same, with each at nearly 20 million, but as of 2003 bike production had climbed to over 100 million per year compared with 42 million cars. This growth in bicycle sales reflects growth in the ranks of those reaching the bicycle level of affluence, principally in Asia. Among industrial countries, the urban transport model being pioneered in the Netherlands and Denmark, where bikes are featured prominently, gives a sense of the bicycle's future role worldwide.^^63^^\n\nAs bicycle use expands, interest in battery-assisted bikes is also growing. Similar to existing bicycles, except for a tiny battery-powered electric motor that can either power the bicycle entirely or assist elderly riders or those living in hilly terrain, its soaring sales are expected to continue climbing.^^64^^\n\nYet another growth industry is raising water productivity. Just as the last half-century was devoted to raising land productivity, this half-century will be focused on raising water productivity. Irrigation technologies will become more efficient. The continuous recycling of urban water supplies, already started in some cities, will become common, replacing the "flush and forget" system.\n\nAs oil prices rise, teleconferencing gains appeal. To save fuel and time, individuals will be "attending" conferences electronically with both audio and visual connections. One day there will likely be literally thousands of firms organizing electronic conferences.\n\nOther promising growth industries are solar cell manufacturing, light rail construction, and tree planting. For the 1.7 billion people living in developing countries and villages that lack electricity, the mass production of solar cells is the best bet for electrification. As people tire of traffic congestion and pollution, cities throughout the world are restricting car use and turning to light rail to provide mobility. As efforts to reforest the earth gain momentum, and as tree plantations expand, tree planting will emerge as a leading economic activity.\n\nRestructuring the global economy will create not only new industries, but also new jobs - indeed, whole new professions and new specialties within professions. Turning to wind in a big way will require thousands of wind meteorologists to analyze potential wind sites, identifying the best sites for wind farms. The role of wind meteorologists in the new economy will be comparable to that of petroleum geologists in the old economy.\n\nThere is a growing demand for environmental architects who can design buildings that are energy- and materials-efficient and that maximize natural heating, cooling, and lighting. In a future of water scarcity, watershed hydrologists will be needed to study the local hydrological cycle, including the movement of underground water, and to determine the sustainable yield of aquifers. They will be at the center of watershed management regimes.\n\nAs the world shifts from a throwaway economy, engineers will be needed to design products that can be recycled - from cars to computers. Once products are designed to be disassembled quickly and easily into component parts and materials, comprehensive recycling is relatively easy. These engineers will be responsible for closing the materials loop, converting the linear flow-through (throwaway) economy into a recycling economy.\n\nIn countries with a wealth of geothermal energy, it will be up to geothermal geologists to locate the best sites either for power plants or for tapping this underground energy directly to heat buildings. Retraining petroleum geologists to master geothermal technologies is one way of satisfying the likely surge in demand for geothermal geologists.\n\nAnother pressing need, particularly in developing countries, is for sanitary engineers who can design sewage systems using waterless, odorless, composting toilets, a trend that is already under way in some water-scarce communities. Yet another growing demand will be for agronomists who specialize in multiple cropping and intercropping. This requires an expertise both in the breeding and selection of crops that can fit together in a tight rotation in various locales and in agricultural practices that facilitate multiple cropping.\n\nCorporations will obviously be challenged by economic restructuring, but so too will universities. Economic restructuring means a demand for new professions such as wind meteorologists, energy architects, and recycling engineers and thus for courses to train tomorrow's professionals.\n\n[[12.6 - The Environmental Revolution]]\n\n[[12.7 - Additional Resources]]\n\n[[12.8 - Notes]]\n\n[[13 - Plan B: Building a New Future]]
Restructuring the global economy according to the principles of ecology represents the greatest investment opportunity in history. In scale, the Environmental Revolution is comparable to the Agricultural and Industrial Revolutions that preceded it.\n\nThe Agricultural Revolution involved restructuring the food economy, shifting from a nomadic life-style based on hunting and gathering to a settled life-style based on tilling the soil. Although agriculture started as a supplement to hunting and gathering, it eventually replaced it almost entirely. The Agricultural Revolution eventually cleared one tenth of the earth's land surface of either grass or trees so it could be plowed and planted to crops. Unlike the hunter-gatherer culture that had little effect on the earth, this new farming culture literally transformed the earth's surface.^^66^^\n\nThe Industrial Revolution has been under way for two centuries, although in some countries it is still in its early stages. At its foundation was a shift from wood to fossil fuels, a shift that set the stage for a massive expansion in economic activity. Indeed, its distinguishing feature is the harnessing of vast amounts of solar energy stored beneath the earth's surface as fossil fuels. While the Agricultural Revolution transformed the earth's surface, the Industrial Revolution is transforming the earth's atmosphere.\n\nThe additional productivity that the Industrial Revolution made possible unleashed enormous creative energies. It also gave birth to new life-styles and to the most environmentally destructive era in human history, setting the world firmly on a course of eventual economic decline.\n\nThe Environmental Revolution resembles the Industrial Revolution in that each is dependent on the shift to a new energy source. And like both earlier revolutions, the Environmental Revolution will affect the entire world.\n\nThere are differences in scale, timing, and origin among the three revolutions. Unlike the first two, the Environmental Revolution must be compressed into a matter of decades. The other revolutions were driven by new discoveries, by advances in technology, whereas this revolution, while it will be facilitated by new technologies, is being driven by our need to make peace with nature.\n\nAs noted earlier, there has not been an investment situation like this before. The $1.7 trillion that the world spends now each year on oil, the leading source of energy, provides some insight into how much it could spend on energy in the eco-economy. One difference between the investments in fossil fuels and those in wind power, solar cells, and geothermal energy is that the latter are not depletable.^^67^^\n\nFor developing countries dependent on imported oil, the new energy sources promise to free up capital for investment in domestic energy sources. Not many countries have their own oil fields, but all have wind and solar energy waiting to be harnessed. In terms of economic expansion and job generation, these new energy technologies are a godsend. Investments in energy efficiency will grow rapidly simply because they are profitable. In virtually all countries, saved energy is the cheapest source of new energy.\n\nThere are also abundant investment opportunities in the food economy. It is likely that the world demand for seafood, for example, will increase at least by half over the next 50 years, and perhaps much more. If so, fish farming output - now 42 million tons a year - will roughly need to double, as will the investments in fish farming. Although aquaculture's growth is likely to slow from the 9 percent a year of the last decade, it nonetheless presents a promising investment opportunity.^^68^^\n\nA similar situation exists for tree plantations. As of 2000, tree plantations covered some 187 million hectares. An expansion of these by at least half will be needed both to satisfy future demand and to reduce pressures on natural forests.^^69^^\n\nNo sector of the global economy will be untouched by the Environmental Revolution. In this new economy, some companies will be winners and some will be losers. Those who participate in building the new economy will be the winners. Those who cling to the past risk becoming part of it.\n\n[[12.7 - Additional Resources]]\n\n[[12.8 - Notes]]\n\n[[13 - Plan B: Building a New Future]]

As we look to the future, two questions loom large. Is civilizational decline under way? And how can we tell? Among the early social signs of possible decline are a widespread drop in life expectancy, growing numbers of hungry people, and a lengthening list of failed and failing states. For the first time in the modern era, life expectancy for a large segment of humanity - the 750 million people living in sub-Saharan Africa - has dropped precipitously, falling from 61 years to 48 years as a result of the HIV/AIDS epidemic.^^1^^\n\nOver the last half-century, the number of people suffering from hunger was declining, but recently this progress was reversed as the number rose from 826 million in 1998 to 852 million in 2002. With business as usual, the number of hungry will likely continue to rise, reinforcing concerns about food security. And now we have a new wildcard in the food security deck, the fast-growing conversion of foodstuffs, such as wheat, corn, soybeans, and sugarcane, into automotive fuel. As the number of ethanol distilleries and biodiesel refineries multiplies, this threat will expand. Could food supply be the weak link in our modern civilization, as it was for the Sumerians, the Mayans, and the Easter Islanders?^^2^^\n\nPerhaps the most disturbing recent development is the growing list of failed states. The //Foreign Policy// article discussed in Chapter 6 lists some 60 countries that have failed, are failing, or are at risk of failing. Governments are being overwhelmed by demographic and environmental forces. After decades of rapid population growth, many governments are suffering from demographic fatigue. With leaders unable to cope with ever-growing populations, environmental life-support systems are disintegrating and social services are breaking down.^^3^^\n\nHow many states have to fail before our global civilization fails? Each additional failed state further weakens the capacity of the international community to maintain stability in the monetary system, to control the spread of infectious diseases, and to deal with local famine threats. At some point, as the number of failing states multiplies, global systems begin to fail.\n\nWe know that sustaining progress depends on restructuring the global economy, shifting from a fossil-fuel-based, automobile-centered, throwaway economy to one based on renewable energy sources, a diverse transportation system, and a comprehensive reuse/recycle materials system. This can be done largely by restructuring taxes and subsidies. Sustaining progress also means eradicating poverty, stabilizing population, and restoring the earth's natural systems. Securing the additional public outlays needed to reach these goals depends on reordering fiscal priorities in response to the new threats to our security.\n\nIn this mobilization, the scarcest resource of all is time. The temptation is to reset the clock, but we cannot. Nature is the timekeeper.\n\n[[13.1 - Listening for Wake-up Calls]]\n\n[[13.2 - A Wartime Mobilization]]\n\n[[13.3 - Mobilizing to Save Civilization]]\n\n[[13.4 - A Call to Greatness]]\n\n[[13.5 - You and Me]]\n\n[[13.6 - Additional Resources]]\n\n[[13.7 - Notes]]\n\n----\nDownload pdf version of Chapter 13\n\n 21pp. (73 Kb)
We are entering a new world. Of that there can be little doubt. What we do not know is whether it will be a world of decline and collapse or a world of environmental restoration and economic progress. Can the world mobilize quickly enough? Where will the wake-up calls come from? What form will they take? Will we hear them?\n\nIn the eyes of many, Hurricane Katrina was just such a wake-up call. Until recently, the most costly weather-related events on record were Hurricane Andrew, which struck Florida in 1992, and the flooding in China's Yangtze River basin in 1998, each causing an estimated $30 billion in damage. When Hurricane Katrina hit the U.S. Gulf Coast in late summer 2005, devastating New Orleans, its estimated cost was $200 billion - nearly seven times the previous record. Higher surface water temperatures helped make Katrina one of the most powerful storms ever to make landfall in the United States.^^4^^\n\nIn 1995, an intense heat wave in Chicago claimed more than 700 lives, focusing U.S. attention on climate change, but it was a minor event compared with the record 2003 heat wave in Europe that claimed 49,000 lives. France reported 14,800 deaths; Italy more than 18,000. Unfortunately this tragic loss of life was never adequately reported simply because the death toll numbers dribbled out over several months and at different times for each country. Just as the destruction from Hurricane Katrina was several times the previous record, so too the fatalities from this heat wave broke all previous fatality records by severalfold.^^5^^\n\nCould a wake-up call take the form of a flood of environmental refugees? As noted earlier, political leaders in sub-Saharan Africa are talking about planting a 5-kilometer-wide and 7,000-kilometer-long belt of trees across the continent in front of the desert in an effort to stop its advance. Whether the African countries can establish a Great Green Wall, and do it quickly enough to halt the desert's advance, remains to be seen. If they fail, we are looking at millions of refugees as productive land turns to desert.^^6^^\n\nIn September 2005, scientists reported that the melting of ice in the Arctic may have reached a "tipping point." We may have unknowingly crossed one of nature's thresholds. According to one article, the team of scientists "believe global warming is melting Arctic ice so rapidly that the region is beginning to absorb more heat from the sun, causing the ice to melt still further and so reinforcing a vicious cycle of melting and heating." If the ice in the Arctic Sea melts and the region's climate continues to warm, the ice sheet covering Greenland, in some places a mile and a half thick, will eventually disappear. It would raise sea level by 23 feet, inundating many of the world's coastal cities and rice-growing river floodplains.^^7^^\n\nIf it becomes clear that we have set in motion a rise in sea level that we cannot arrest or reverse, how will this affect the way we think about ourselves as individuals and as a society? Will we face a social fracturing between generations, between those who caused the rise in sea level and those who must deal with its consequences?\n\nClimate change, whether it is natural or human-induced, is a source of social stress. Jared Diamond notes that drought figured prominently in the collapse and disappearance of the 600-year-old Anasazi civilization in the southwestern United States shortly after 1150. A shrinking food supply led to conflict and cannibalism in this earlier New World civilization. Three centuries later, the Norse settlement in Greenland collapsed and disappeared during a period of extreme cold. For our modern civilization, it is the rise in temperature that is generating social stress in the form of crop-shrinking heat waves, ice melting, rising seas, and more-destructive storms.^^8^^\n\nIs the record price of oil in late 2005 an aberration or does it reflect something more fundamental - a failure to plan for the depletion of the world's oil reserves? Is it a result of system failure? If so, can the international community pull itself together to stabilize oil prices and avoid both a possible oil-based global economic depression and spreading conflict over access to remaining oil reserves?^^9^^\n\nAre these wake-up calls? If so, they have not yet awakened us. Have we pushed the snooze button so we can sleep a while longer? Or are these issues just too complicated to comprehend? Are we being overwhelmed by complexity, as Joseph Tainter postulates in his book, //The Collapse of Complex Societies,// that some earlier civilizations were?^^10^^\n\nThis chapter is frustratingly difficult to write because it is not about what we need to do or how to do it, but rather about how to mobilize support to do it. How do we convince ourselves of the gravity and urgency of the situation we face? It is partly a matter of overcoming vested interests and social inertia, and partly a matter of raising public understanding of the threats facing civilization.\n\nFacing many threats simultaneously means setting priorities. Terrorism is one of those threats. No question. But it is not even close to being the top threat facing our early twenty-first century civilization. Population growth, climate change, poverty, spreading water shortages, rising oil prices, and a potential rise in food prices that could lead to unprecedented political instability are the leading threats.\n\nNew threats call for new priorities and new responses. Old priorities are hopelessly outmoded. Heavy investments in military power and sophisticated weapons systems, for instance, are of little use in dealing even with terrorism, much less climate change or aquifer depletion. Historically, it was aggressor nations building and concentrating military power that threatened the rest of the world. In contrast, today it is failing states, those that are disintegrating internally, that threaten future progress and stability.\n\nIn our new world, we need political leaders who can see the big picture, who understand the relationship between the economy and its environmental support systems. And since the principal advisors to governments are economists, we need economists who can think like ecologists. Unfortunately they are rare. Ray Anderson, founder and chairman of Atlanta-based Interface, a leading world manufacturer of industrial carpet, is especially critical of economics as it is being taught in many universities, noting that "we continue to teach economics students to trust the 'invisible hand' of the market, when the invisible hand is clearly blind to the externalities, and treats massive subsidies, such as a war to protect oil for the oil companies, as if the subsidies were deserved. Can we really trust a //blind// invisible hand to allocate resources rationally?"^^11^^\n\nSome point out that neo-classical economics does recognize external costs as something to be avoided. True. But do economics instructors tabulate those costs and analyze their effects on the earth's ecosystem and its capacity to sustain the economy? For example, how many economic courses teach that our fossil-fuel-based, automobile-centered, throwaway economy is simply not a viable economic model for the world? And that the biggest challenge the world faces is to build a new economy that will sustain economic progress?\n\n[[13.2 - A Wartime Mobilization]]\n\n[[13.3 - Mobilizing to Save Civilization]]\n\n[[13.4 - A Call to Greatness]]\n\n[[13.5 - You and Me]]\n\n[[13.6 - Additional Resources]]\n\n[[13.7 - Notes]]
As we contemplate mobilizing to rescue a planet under stress and a civilization in trouble, we see both similarities and contrasts with the mobilization for World War II. In this earlier mobilization, there was an economic restructuring, but it was temporary. Mobilizing to save civilization, in contrast, requires a permanent economic restructuring.\n\nThe U.S. entry into World War II is a fascinating case study in rapid mobilization. Initially, the United States resisted involvement in the war and responded only after it was directly attacked at Pearl Harbor on December 7, 1941. But respond it did. After an all-out commitment, the U.S. engagement helped turn the tide of war, leading the Allied Forces to victory within three-and-a-half years.^^12^^\n\nIn his State of the Union address on January 6, 1942, one month after the bombing of Pearl Harbor, President Roosevelt announced the country's arms production goals. The United States, he said, was planning to produce 45,000 tanks, 60,000 planes, 20,000 anti-aircraft guns, and 6 million tons of merchant shipping. He added, "Let no man say it cannot be done."^^13^^\n\nNo one had ever seen such huge arms production numbers. But Roosevelt and his colleagues realized that the largest concentration of industrial power in the world at that time was in the U.S. automobile industry. Even during the Depression, the United States was producing 3 million or more cars a year. After his State of the Union address, Roosevelt met with automobile industry leaders and told them that the country would rely heavily on them to reach these arms production goals. Initially they wanted to continue making cars and simply add on the production of armaments. What they did not yet know was that the sale of private automobiles would soon be banned. From the beginning of April 1942 through the end of 1944, nearly three years, there were essentially no cars produced in the United States.^^14^^\n\nIn addition to a ban on the production and sale of cars for private use, residential and highway construction was halted, and driving for pleasure was banned. A rationing program was also introduced. Strategic goods - including tires, gasoline, fuel oil, and sugar - were rationed beginning in 1942. Cutting back on consumption of these goods freed up material resources to support the war effort.^^15^^\n\nThe year 1942 witnessed the greatest expansion of industrial output in the nation's history - all for military use. Wartime aircraft needs were enormous. They included not only fighters, bombers, and reconnaissance planes, but also the troop and cargo transports needed to fight a war on two distant fronts. From the beginning of 1942 through 1944, the United States far exceeded the initial goal of 60,000 planes, turning out 229,600 aircraft, a fleet so vast it is hard even today to visualize it. Equally impressive, by the end of the war more than 5,000 ships were added to the 1,000 or so that made up the American Merchant Fleet in 1939.^^16^^\n\nIn her book //No Ordinary Time,// Doris Kearns Goodwin describes how various firms converted. A sparkplug factory was among the first to switch to the production of machine guns. Soon a manufacturer of stoves was producing lifeboats. A merry-go-round factory was making gun mounts; a toy company was turning out compasses; a corset manufacturer was producing grenade belts; and a pinball machine plant began to make armor-piercing shells.^^17^^\n\nIn retrospect, the speed of this conversion from a peacetime to a wartime economy is stunning. The harnessing of U.S. industrial power tipped the scales decisively toward the Allied Forces, reversing the tide of war. Germany and Japan, already fully extended, could not counter this effort. Winston Churchill often quoted his foreign secretary, Sir Edward Grey: "The United States is like a giant boiler. Once the fire is lighted under it, there is no limit to the power it can generate."^^18^^\n\nThis mobilization of resources within a matter of months demonstrates that a country and, indeed, the world can restructure the economy quickly if it is convinced of the need to do so. Many people - although not yet the majority - are already convinced of the need for a wholesale economic restructuring. The purpose of this book is to convince more people of this need, helping to tip the balance toward the forces of change and hope.\n\n[[13.3 - Mobilizing to Save Civilization]]\n\n[[13.4 - A Call to Greatness]]\n\n[[13.5 - You and Me]]\n\n[[13.6 - Additional Resources]]\n\n[[13.7 - Notes]]
Mobilizing to save civilization means restructuring the economy, restoring the economy's natural support systems, eradicating poverty, and stabilizing population. We have the technologies, economic instruments, and financial resources to do this. The United States, the wealthiest society that has ever existed, has the resources to lead this effort. Jeffrey Sachs of Columbia University's Earth Institute sums it up well: "The tragic irony of this moment is that the rich countries are so rich and the poor so poor that a few added tenths of one percent of GNP from the rich ones ramped up over the coming decades could do what was never before possible in human history: ensure that the basic needs of health and education are met for all impoverished children in this world. How many more tragedies will we suffer in this country before we wake up to our capacity to help make the world a safer and more prosperous place not only through military might, but through the gift of life itself?"^^19^^\n\nIt is not possible to put a precise price tag on the changes needed to move our twenty-first century civilization off the overshoot-and-collapse path and onto a path that will sustain economic progress. What we can do, however, is provide some rough estimates of the scale of effort needed.\n\nAs discussed in Chapter 7, the additional external funding needed to achieve universal primary education in the more than 80 developing countries that require help, for instance, is conservatively estimated by the World Bank at $12 billion per year. Funding for an adult literacy program based largely on volunteers will take an estimated additional $4 billion annually. Providing for the most basic health care in developing countries is estimated at $33 billion by the World Health Organization. The additional funding needed to provide reproductive health care and family planning services to all women in developing countries is less than $7 billion a year.^^20^^\n\nClosing the condom gap by providing the additional 9.5 billion condoms needed to control the spread of HIV in the developing world and Eastern Europe requires $2 billion - $285 million for condoms and $1.7 billion for AIDS prevention education and condom distribution. The cost of extending school lunch programs to the 44 poorest countries is $6 billion. An estimated $4 billion per year would cover the cost of assistance to preschool children and pregnant women in these countries. Altogether, the cost of reaching basic social goals comes to $68 billion a year.^^21^^\n\nAs noted in Chapter 8, a poverty eradication effort that is not accompanied by an earth restoration effort is doomed to fail. Protecting topsoil, reforesting the earth, restoring oceanic fisheries, and other needed measures will cost an estimated $93 billion of additional expenditures per year. The most costly activities, protecting biological diversity at $31 billion and conserving soil on cropland at $24 billion, account for over half of the earth restoration annual outlay.\n\nCombining social goals and earth restoration components into a Plan B budget yields an additional annual expenditure of $161 billion, roughly one third of the current U.S. military budget or one sixth of the global military budget. (See Table 13-1.)^^22^^\n\n<<tiddler Table 13-1>>\n\nUnfortunately, the United States continues to focus on building an ever-stronger military, largely ignoring the threats posed by continuing environmental deterioration, poverty, and population growth. Its proposed defense budget for 2006, including $50 billion for the military operations in Iraq and Afghanistan, brings the U.S. projected military expenditure to $492 billion. (See Table 13-2.) Other North Atlantic Treaty Organization members spend $209 billion a year on the military. Russia spends about $65 billion, and China, $56 billion. U.S. military spending is now roughly equal to that of all other countries combined. As the late Eugene Carroll, Jr., a retired admiral, astutely observed, "For forty-five years of the Cold War we were in an arms race with the Soviet Union. Now it appears we are in an arms race with ourselves."^^23^^\n\nIt is decision time. Like earlier civilizations that got into environmental trouble, we can decide to stay with business as usual and watch our modern economy decline and eventually collapse, or we can consciously move onto a new path, one that will sustain economic progress. In this situation, no action is actually a decision to stay on the decline-and-collapse path.\n\n<<tiddler Table 13-2>>\n\nIt is hard to find the words to convey the gravity of our situation and the momentous nature of the decision we are about to make. How can we convey the urgency of this moment in history? Will tomorrow be too late? Do enough of us care deeply enough to turn the tide now?\n\nWill someone somewhere one day erect a tombstone for our civilization? If so, how will it read? It cannot say we did not understand. We do understand. It cannot say we did not have the resources. We do have the resources. It can only say we were too slow to respond to the forces undermining our civilization. Time ran out.\n\nNo one can argue today that we do not have the resources to eradicate poverty, stabilize population, and protect the earth's natural resource base. We can get rid of hunger, illiteracy, disease, and poverty, and we can restore the earth's soils, forests, and fisheries. Shifting one sixth of the world military budget to the Plan B budget would be more than adequate to move the world onto a path that would sustain progress. We can build a global community where the basic needs of all the earth's people are satisfied - a world that will allow us to think of ourselves as civilized.\n\nThis economic restructuring depends on tax restructuring, on getting the market to be ecologically honest. The benchmark of political leadership in all countries will be whether or not leaders succeed in restructuring the tax system as, for example, Germany and Sweden have done. This is the key to restructuring the energy economy - both to stabilize climate and to make the transition to the post-petroleum world.^^24^^\n\nIt is easy to spend hundreds of billions in response to terrorist threats, but the reality is that the resources needed to disrupt a modern economy are small, and a U.S. Department of Homeland Security, however heavily funded, provides only minimal protection from suicidal terrorists. The challenge is not to provide a high-tech military response to terrorism, but to build a global society that is environmentally sustainable and equitable - one that restores hope for everyone. Such an effort would more effectively undermine the support for terrorism than any increase in military expenditures, than any new weapons systems, however advanced.\n\nAs we look at the environmentally destructive trends that are undermining our future, the world is desperately in need of visible evidence that we can indeed turn things around at the global level. Fortunately, the steps to reverse destructive trends or to initiate constructive new trends are often mutually reinforcing or win-win solutions. For example, efficiency gains that reduce oil use also reduce carbon emissions and air pollution. Steps to eradicate poverty simultaneously help eradicate hunger and stabilize population. Reforestation fixes carbon, increases aquifer recharge, and reduces soil erosion. Once we get enough trends headed in the right direction, they will often reinforce each other.\n\nWhat the world needs now is a major success story in reducing carbon emissions and dependence on oil to bolster hope in the future. If the United States, for instance, were to decide to replace the existing fleet of inefficient gasoline-burning vehicles with super-efficient gas/electric hybrids over the next 10 years, gasoline use could easily be cut in half. Beyond this, a gas/electric hybrid with an additional storage battery and a plug-in capacity sets the stage for using electricity for short distance driving, such as the daily commute or grocery shopping. Then, as suggested in Chapter 10, if we invest in thousands of wind farms, Americans could do most of their short-distance driving essentially with wind energy, dramatically reducing pressures on the world's oil supplies.^^25^^\n\nWith many U.S. automobile assembly lines idled, it would be a relatively simple matter to retool some of them to produce wind turbines, enabling the country to quickly harness its vast wind energy potential. This would be a rather modest initiative compared with the World War II restructuring, but it would help the world to see that restructuring an economy is entirely doable and that it can be done quickly, profitably, and in a way that enhances national security by reducing dependence on vulnerable oil supplies. Globally, it would help slow the potentially disruptive rise in oil prices. Beyond this, it would reduce carbon emissions, helping to stabilize climate. And, most important, it would restore public confidence in government.\n\n[[13.4 - A Call to Greatness]]\n\n[[13.5 - You and Me]]\n\n[[13.6 - Additional Resources]]\n\n[[13.7 - Notes]]
History judges political leaders by whether or not they respond to the great issues of their time. For today's leaders, that issue is how to move the global economy onto an environmentally sound path. We need a national political leader to step forward, an environmental Churchill, to rally the world around this mobilization.\n\nFollowing the terrorist attacks on the World Trade Center and the Pentagon on September 11, 2001, several world leaders suggested a twenty-first century variation of the Marshall Plan to deal with poverty and its symptoms, arguing that in an increasingly integrated world, abject poverty and great wealth cannot coexist. Gordon Brown, U.K. Chancellor of the Exchequer, notes that, "Like peace, prosperity was indivisible and to be sustained, it had to be shared." Brown sees a Marshall Plan-like initiative not as aid in the traditional sense, but as an investment in the future.^^26^^\n\nFrench President Jacques Chirac, a political conservative, told the Earth Summit in Johannesburg in September 2002 that "the world needed an international tax to fight world poverty." He suggested a tax on airplane tickets, carbon emissions, or international currency trading. To illustrate his commitment, Chirac announced that over the next five years France would double its development aid, reaching the internationally agreed upon goal of devoting 0.7 percent of gross domestic product to aid. Going beyond economic issues, he also suggested the creation of a world environment organization to coordinate efforts to build an environmentally sustainable economy.\n\nThe urgency of the situation we are now in means that individual countries will simply have to take initiatives on such things as reducing carbon emissions without waiting for a new international agreement to be negotiated. It took the better part of a decade to negotiate the grossly inadequate Kyoto Protocol. We no longer have time for prolonged negotiations.^^28^^\n\nIn 1999, when the German government decided to launch a tax restructuring that would raise taxes on energy use and reduce those on income, a step designed to both reduce carbon emissions and increase employment, its leaders did not insist that the rest of the world or even other European countries agree to do it. They did it because they thought it was the right thing to do for Germany. If countries take strong steps to reverse the trends undermining our future, other countries are certain to follow. At this point in history, the best way to lead is by doing.^^29^^\n\nSimilarly, when Sweden decided on an even more basic environmentally guided restructuring of its tax system, it did not insist that others also do so. It acted on its own and decisively, providing an example for other countries.^^30^^\n\nIn the United States, frustration with Washington's decision to ignore the Kyoto Protocol has led mayors of more than 180 cities to band together to honor the Protocol's goals of cutting carbon emissions 7 percent below the 1990 level over the next decade. In early June 2005, Fred Pearce wrote in the //New Scientist//, "Last month, in the boldest repudiation of a national government yet, a group of American mayors swept aside the Bush administration's refusal to cut carbon emissions." Among the cities were some of the country's largest: Los Angeles, Denver, and New York. Initiatives to achieve the carbon cutting goals are numerous and vary widely among cities. In Salt Lake City, the city authority is buying wind-generated electricity. New York City is converting its municipal motor fleet to gas-electric hybrid vehicles.^^31^^\n\nA revolt is also under way at the state level. Nine states in the northeastern United States are negotiating a pact to reduce carbon emissions from power plants. State legislatures elsewhere in the country are adopting renewable portfolio standards, which establish a minimal amount of future electricity that must come from renewable energy sources. Among them are California, Colorado, Iowa, Minnesota, New York, Pennsylvania, Texas, and Wisconsin.^^32^^\n\nParalleling the need for political leadership is the need for media leadership. Given the urgency of action, and of mobilizing support for these actions, the world faces an unprecedented public education challenge. Turning the tide depends on the communications media rising to the occasion to raise public awareness about the gravity of our situation and the urgency of responding to it. Only the communications media can disseminate information on the scale needed and in the time available. No other institution has this capacity.\n\nThis position of the media industry is remarkably similar to that of the U.S. automobile industry in World War II. Like the auto industry some 60 years ago, this is not a responsibility that publishers and editors have asked for or, indeed, that they necessarily want to assume. But there is no alternative. If the communications media worldwide do not take the lead in raising public environmental understanding, the current mobilization will likely fail. We are facing a situation totally different from any faced before, one that requires an entirely new response.\n\nOn January 1, 2005, the //New York Times// took a step in this direction when it devoted four fifths of its op-ed page to a piece by Jared Diamond, based on his book //Collapse: How Societies Choose to Fail or Succeed//. Diamond reflected on the lessons we could draw from earlier civilizations that, like ours, had moved onto an economic path that was environmentally unsustainable.^^33^^\n\nWhat Diamond learned in researching this book was that moving off the decline-and-collapse path back onto an economic path that is environmentally sustainable is not always easy. Some civilizations are able to read the warning signs and change course quickly. Others fail to do so and collapse.^^34^^\n\nThis research makes it clear that environmental mismanagement, if it continues long enough, leads to civilizational collapse. Diamond's article helped launch a public dialogue about the environmental parallels between our contemporary global civilization and the earlier civilizations discussed in the book.\n\nNongovernmental environmental groups are also answering the call. By selecting Wangari Maathai for the 2004 Peace Prize, the Nobel Peace Prize committee was recognizing grassroots environmental leadership at its best. Nearly 30 years ago, Maathai founded the Green Belt Movement, an organization that mobilized people at the local level to plant some 30 million trees in Kenya. As Geoffrey Dabelko wrote in //Grist//, the movement mobilized thousands of women, offering them empowerment, education, and even family planning. In 2002, Maathai was elected to Parliament and was shortly thereafter appointed Deputy Minister of Environment by the new government.^^35^^\n\nCorporate leaders are also getting involved. Ted Turner, founder of CNN, broke new ground for individual philanthropy when he announced in 1997 a gift of $1 billion to the United Nations to support population stabilization, environmental protection, and the provision of health care. He created the UN Foundation to serve as a vehicle through which the resources could be transferred. Turner could have waited until his death to leave a bequest for the earth, but given the urgency of the situation the world was facing, he argued that billionaires needed to respond now before problems become unmanageable.^^36^^\n\nTurner undoubtedly influenced Bill Gates, founder of Microsoft, as well as other newly minted billionaires. Channeling his wealth as the world's richest individual into a foundation and allocating it to improve health in developing countries, including initiatives ranging from massive childhood vaccinations to curbing the HIV epidemic, Gates is saving millions of lives.^^37^^\n\nThere is a growing sense among the more thoughtful political leaders that business as usual is no longer a viable option, that unless we respond to the environmental threats to our twenty-first century civilization, we are in trouble. The prospect of failing states is growing as mega-threats such as the HIV epidemic, hydrological poverty, and land hunger threaten to overwhelm countries on the lower rungs of the global economic ladder.\n\n[[13.5 - You and Me]]\n\n[[13.6 - Additional Resources]]\n\n[[13.7 - Notes]]
One of the questions I am frequently asked when I am speaking in various countries is, Given the environmental problems that the world is facing, can we make it? That is, can we avoid economic decline and civilizational collapse? My answer is always the same: it depends on you and me, on what you and I do to reverse these trends. It means becoming politically active. Saving our civilization is not a spectator sport.\n\nWe have moved into this new world so rapidly that we have not yet fully grasped the meaning of what is happening. Traditionally, concern for our children has translated into ensuring their health care and getting them the best education possible. But if we do not act quickly to reverse the deterioration of the earth's environmental systems, eradicate poverty, and stabilize population, their world will be declining economically and disintegrating politically. Today, securing our children's future means not only investing in their education and health care, but also investing in a program to reverse the trends that are undermining their future.\n\nAs individuals, we should continue our memberships in environmental and population organizations. We need to improve local recycling programs. We need to vote with our pocketbooks. For example, buying Green Power certificates helps drive investment in renewable energy. We need to do all the things we are now doing to protect the environment. But they are not enough. We have been doing these things for the last 35 years. We have won a lot of local battles, but we are losing the war.\n\nThe two overriding challenges are to restructure taxes and reorder fiscal priorities. Saving civilization means restructuring the economy - and at wartime speed. It means restructuring taxes to get the market to tell the ecological truth. And it means reordering fiscal priorities to get the resources needed to restore the earth, eradicate poverty, and stabilize population. Write or e-mail your elected representative about the need for tax restructuring to create an honest market. Remind him or her that corporations that left costs off the books appeared to prosper in the short run, only to collapse in the longer run.\n\nOr better yet, meet with your elected representatives to discuss why we need to raise environmental taxes and reduce income taxes. Work with like-minded friends and associates toward this goal. Put together a delegation to meet with your elected representative. Feel free to download the information on tax restructuring in the preceding chapter from our Web site to use in these efforts. If we cannot restructure the tax system to enable the market to tell the truth, we almost certainly will not make it.\n\nLet your political representatives know that a world spending nearly $1 trillion a year for military purposes is simply out of sync with reality in a situation where the future of civilization is in question. Ask them if $161 billion per year is an unreasonable expenditure to save civilization. Ask them if diverting one sixth of the global military budget to saving civilization is too costly.\n\nIf you like to write, try your hand at an op-ed piece for your local newspaper on the need to raise taxes on environmentally destructive activities and offset this with a lowering of income taxes. Try a letter to the editor. Organize a letter writing campaign, urging people to contact their elected representatives and local media outlets on this issue.\n\nPush for the inclusion of poverty eradication, family planning, and reforestation in international assistance programs. Lobby for an increase in these appropriations and a cut in military appropriations, pointing out that advanced weapons systems are useless in dealing with the new threats to our civilization. Someone needs to speak on behalf of our children and grandchildren because it is their world and their futures that are at stake.\n\nEducate yourself on environmental issues and on what happened to earlier civilizations that also found themselves in environmental trouble - and help your friends to become better informed. On this subject I recommend //Collapse// by Jared Diamond and //A Short History of Progress// by Ronald Wright. To understand the case for eradicating poverty, read "Can Extreme Poverty Be Eliminated?" by Jeffrey Sachs in the September 2005 issue of //Scientific American//. To gain a sense of the enormous potential for boosting energy efficiency, read "More Profit with Less Carbon" by Amory Lovins in the same issue.^^38^^\n\nRemember, challenging though the situation may be, there are signs of the new economy emerging all over the world. We see them in the wind farms of Europe, the fast-growing U.S. fleet of gas-electric hybrid cars, the reforested hills of South Korea, the family planning program of Iran, the massive eradication of poverty in China, and the solar rooftops of Japan.\n\nWhat we need to do is doable. Sit down and map out your own personal plan and timetable for what you want to do to move the world from a path headed toward economic decline to one of sustained economic progress. Sketch out a plan for the next year of the things you want to do, how you hope to do them, and whom you can work with to achieve the only goal that really counts - the preservation of civilization. What could be more rewarding?\n\nThe choice is ours - yours and mine. We can stay with business as usual and preside over an economy that continues to destroy its natural support systems until it destroys itself, or we can adopt Plan B and be the generation that changes direction, moving the world onto a path of sustained progress. The choice will be made by our generation, but it will affect life on earth for all generations to come.\n\n[[13.6 - Additional Resources]]\n\n[[13.7 - Notes]]

When the price of oil climbed above $50 a barrel in late 2004, public attention began to focus on the adequacy of world oil supplies - and specifically on when production would peak and begin to decline. Analysts are far from a consensus on this issue, but several prominent ones now believe that the oil peak is imminent.^^1^^\n\nOil has shaped our twenty-first century civilization, affecting every facet of the economy from the mechanization of agriculture to jet air travel. When production turns downward, it will be a seismic economic event, creating a world unlike any we have known during our lifetimes. Indeed, when historians write about this period in history, they may well distinguish between before peak oil (BPO) and after peak oil (APO).\n\nThe peaking of oil production is approaching at a time when the world is facing many challenges, such as rising temperatures, falling water tables, and numerous other damaging environmental trends. Adjusting to a shrinking oil supply is part of the economic restructuring needed to put the economy on a path that will sustain progress.\n\n[[2.1 - The Coming Decline of Oil]]\n\n[[2.2 - The Oil Intensity of Food]]\n\n[[2.3 - The Falling Wheat-Oil Exchange Rate]]\n\n[[2.4 - Food and Fuel Compete for Land]]\n\n[[2.5 - Cities and Suburbs After Peak Oil]]\n\n[[2.6 - The World After Oil Peaks]]\n\n[[2.7 - Additional Resources]]\n\n[[2.8 - Notes]]\n\n[[3 - Emerging Water Shortages]]\n\n----\nDownload pdf version of Chapter 2\n\n 21pp. (80 Kb)
The oil prospect can be analyzed in several different ways. Oil companies, oil consulting firms, and national governments rely heavily on computer models to project future oil production and prices. The results from these models vary widely according to the quality of data and the assumptions fed into the models. Here we review several different analytical methods.\n\nOne approach - use of the reserves/production relationship to gain a sense of future production trends - was pioneered several decades ago by the legendary King Hubbert, a geologist with the U.S. Geological Survey. Given the nature of oil production, Hubbert theorized that the time lag between the peaking of new discoveries and the peaking of production was predictable. Noting that the discovery of new reserves in the United States had peaked around 1930, he predicted that U.S. oil production would peak in 1970. He hit it right on the head. As a result of this example and other more recent country experiences, his basic model is now used by many oil analysts.^^2^^\n\nA second approach, separating the world's principal oil-producing countries into two groups - those where production is falling and those where it is still rising - is illuminating. Of the 23 leading oil producers, output appears to have peaked in 15 and to still be rising in eight. The post-peak countries range from the United States (the only country other than Saudi Arabia to ever pump more than 9 million barrels of oil per day) and Venezuela (where oil production peaked in 1970) to the two North Sea oil producers, the United Kingdom and Norway, where production peaked in 1999 and 2000 respectively. U.S. oil production, which peaked at 9.6 million barrels a day in 1970, dropped to 5.4 million barrels a day in 2004 - a decline of 44 percent. Venezuela's production has dropped 31 percent since 1970.^^3^^\n\nThe eight pre-peak countries are dominated by the world's leading oil producers, Saudi Arabia and Russia, producing roughly 11 million and 9 million barrels of oil a day in the fall of 2005. Other countries with substantial potential for increasing production are Canada, largely because of its tar sands, and Kazakhstan, which is still developing its oil resources. The other four pre-peak countries are Algeria, Angola, China, and Mexico.^^4^^\n\nThe biggest question mark among these eight countries is Saudi Arabia. Its production technically peaked in 1980 at 9.9 million barrels a day and output is now nearly 1 million barrels a day below that. It is included as a country with rising production only on the basis of statements by Saudi officials that the country could produce far more. However, some analysts doubt whether the Saudis can raise output much beyond its current production. Some of its older oil fields are largely depleted, and it remains to be seen whether pumping from new fields will be sufficient to more than offset the loss from the old ones.^^5^^\n\nThis analysis comes down to whether production will actually increase enough in the eight pre-peak countries to offset the declines under way in the 15 countries where production has already peaked. In volume of output, the two groups have essentially the same total production capacity. If production begins to fall in any one of the eight, however, this may well tilt the global balance to decline.^^6^^\n\nA third way to consider oil production prospects is to look at the actions of the major oil companies themselves. While some CEOs sound very bullish about the growth of future production, their actions suggest a less confident outlook.\n\nOne bit of evidence of this is the decision by leading oil companies to invest heavily in buying up their own stocks. Exxon-Mobil, for example, with the largest quarterly profit of any company on record - $8.4 billion in the last quarter of 2004 - invested nearly $10 billion in buying back its own stock. ChevronTexaco used $2.5 billion of its profits to buy back stock. With little new oil to be discovered and world oil demand growing fast, companies appear to be realizing that their reserves will become even more valuable in the future.^^7^^\n\nClosely related to this behavior is the lack of any substantial increases in exploration and development in 2005 even though oil prices are well above $50 a barrel. This suggests that the companies agree with petroleum geologists who say that 95 percent of all the oil in the world has already been discovered. "The whole world has now been seismically searched and picked over," says independent geologist Colin Campbell. "Geological knowledge has improved enormously in the past 30 years and it is almost inconceivable now that major fields remain to be found." This also implies that it may take a lot of costly exploration and drilling to find that remaining 5 percent.^^8^^\n\nThis shrinkage of reserves is strikingly evident in the ratio between new oil discoveries and production of the major oil companies. Among those reporting that their 2004 oil production greatly exceeded new discoveries were Royal Dutch/Shell, ChevronTexaco, and Conoco-Phillips. The bottom line is that the oil reserves of major companies are shrinking yearly. On a global scale, geologist Walter Youngquist, author of //GeoDestinies: The Inevitable Control of Earth Resources Over Nations and Individuals//, notes that in 2004 the world produced 30.5 billion barrels of oil but discovered only 7.5 billion barrels of new oil.^^9^^\n\nThe influence on oil production in the years immediately ahead that is most difficult to measure is the emergence of what I call a "depletion psychology." Once oil companies or oil-exporting countries realize that output is about to peak, they will begin to think seriously about how to stretch out their remaining reserves. As it becomes clear that even a moderate cut in production may double world oil prices, the long-term value of their oil will become much clearer.\n\nThe geological evidence suggests that world oil production will be peaking sooner rather than later. Matt Simmons, head of the oil investment bank Simmons and Company International and an industry leader, says in reference to new oil fields: "We've run out of good projects. This is not a money issue - if these oil companies had fantastic projects, they'd be out there [developing new fields]." Kenneth Deffeyes, a highly respected geologist and former oil industry employee now at Princeton University, says in his 2005 book, //Beyond Oil//, "It is my opinion that the peak will occur in late 2005 or in the first few months of 2006." Walter Youngquist and A.M. Samsan Bakhtiari of the Iranian National Oil Company both project that oil will peak in 2007.^^10^^\n\nSadad al-Husseini, recently retired as head of exploration and production at Aramco, the Saudi national oil company, discussed the world oil prospect with Peter Maass for the //New York Times//. His basic point was that new oil output coming online had to be sufficient to cover both annual growth in world demand of at least 2 million barrels a day and the annual decline in production from existing fields of over 4 million barrels a day. "That's like a whole new Saudi Arabia every couple of years," Husseini said. "It's not sustainable."^^11^^\n\nWhere are companies looking for more oil? Aside from conventional petroleum, the kind that can easily be pumped to the surface, vast amounts of oil are stored in tar sands and can be produced from oil shale. The Athabasca tar sand deposits in Alberta, Canada, may total 1.8 trillion barrels. Of this total, however, it is thought that not more than 300 billion barrels is recoverable. Venezuela also has a large deposit of extra heavy oil, estimated at 1.2 trillion barrels. Perhaps a third of it can be readily recovered. If Venezuela's heavy oil is developed on a large enough scale, its oil production could one day exceed its 1970 historical peak. Oil shale concentrated in Colorado, Wyoming, and Utah in the United States also holds large quantities of kerogen, an organic material that can be converted into oil and gas.^^12^^\n\nHow much oil can be economically produced from oil shale? In the late 1970s the United States launched a major effort to develop oil shale on the western slope of the Rocky Mountains in Colorado. When oil prices dropped in 1982, the oil shale industry collapsed. Exxon quickly pulled out of its $5-billion Colorado project, and the remaining companies soon followed suit. Since this process requires several barrels of water for each barrel of oil produced, water shortages in the region may limit its revival.^^13^^\n\nThe one project that is moving ahead is the tar sands project in Canada's Alberta Province. This initiative, which began in the early 1980s, is now producing a million barrels of oil per day, enough to supply 5 percent of current U.S. oil use. This tar sand oil is not cheap, however, and it wreaks environmental havoc on a vast scale. Heating and extracting the oil from the sands relies on the extensive use of natural gas, production of which has peaked in North America.^^14^^\n\nThus although these reserves of oil in tar sands and shale may be vast, gearing up for production is a costly, time-consuming process. At best, the development of tar sands and oil shale is likely only to slow the decline in world oil production.^^15^^\n\n[[2.2 - The Oil Intensity of Food]]\n\n[[2.3 - The Falling Wheat-Oil Exchange Rate]]\n\n[[2.4 - Food and Fuel Compete for Land]]\n\n[[2.5 - Cities and Suburbs After Peak Oil]]\n\n[[2.6 - The World After Oil Peaks]]\n\n[[2.7 - Additional Resources]]\n\n[[2.8 - Notes]]\n\n[[3 - Emerging Water Shortages]]
Modern agriculture depends heavily on the use of gasoline and diesel fuel in tractors for plowing, planting, cultivating, and harvesting. Irrigation pumps use diesel fuel, natural gas, and coal-fired electricity. Fertilizer production is also energy-intensive: the mining, manufacture, and international transport of phosphates and potash all depend on oil. Natural gas, however, is used to synthesize the basic ammonia building block in nitrogen fertilizers.^^16^^\n\nIn the United States, for which reliable historical data are available, the combined use of gasoline and diesel fuel in agriculture has fallen from its historical high of 7.7 billion gallons in 1973 to 4.6 billion in 2002, a decline of 40 percent. For a broad sense of the fuel efficiency trend in U.S. agriculture, the gallons of fuel used per ton of grain produced dropped from 33 in 1973 to 13 in 2002, an impressive decrease of 59 percent.^^17^^\n\nOne reason for this was a shift to minimum and no-till cultural practices on roughly two fifths of U.S. cropland. No-till cultural practices are now used on roughly 95 million hectares worldwide, nearly all of them concentrated in the United States, Brazil, Argentina, and Canada. The United States - with 25 million hectares of minimum or no-till - leads the field, closely followed by Brazil.^^18^^\n\nWhile U.S. agricultural use of gasoline and diesel has been declining, in many developing countries it is rising as the shift from draft animals to tractors continues. A generation ago, for example, cropland in China was tilled largely by animals. Today much of the plowing is done with tractors.^^19^^\n\nFertilizer accounts for 20 percent of U.S. farm energy use. Worldwide, the figure may be slightly higher. On average, the world produces 13 tons of grain for each ton of fertilizer used. But this varies widely among countries. For example, in China a ton of fertilizer yields 9 tons of grain, in India it yields 11 tons, and in the United States, 18 tons.^^20^^\n\nU.S. fertilizer efficiency is high because U.S. farmers routinely test their soils to precisely determine crop nutrient needs and because the United States is also the leading producer of soybeans, a leguminous crop that fixes nitrogen in the soil. Soybeans, which rival corn for area planted in the United States, are commonly grown in rotation with corn and, to a lesser degree, with winter wheat. Since corn has a voracious appetite for nitrogen, alternating corn and soybeans in a two-year rotation substantially reduces the nitrogen fertilizer needed for the corn.^^21^^\n\nUrbanization increases demand for fertilizer. As rural people migrate to cities, it becomes more difficult to recycle the nutrients in human waste back into the soil. Beyond this, the growing international food trade can separate producer and consumer by thousands of miles, further disrupting the nutrient cycle. The United States, for example, exports some 80 million tons of grain per year - grain that contains large quantities of basic plant nutrients: nitrogen, phosphorus, and potassium. The ongoing export of these nutrients would slowly drain the inherent fertility from U.S. cropland if the nutrients were not replaced in chemical form.^^22^^\n\nFactory farms, like cities, tend to separate producer and consumer, making it difficult to recycle nutrients. Indeed, the nutrients in animal waste that are an asset to farmers become a liability in large feeding operations, often with costly disposal. As oil, and thus fertilizer, become more costly, the economics of factory farms may become less attractive.\n\nIrrigation, another major energy claimant, is taking more and more energy worldwide. In the United States, close to 19 percent of agricultural energy use is for pumping water. In the other two large food producers - China and India - the number is undoubtedly much higher, since irrigation figures so prominently in both countries.^^23^^\n\nSince 1950 the world's irrigated area has tripled, climbing from 94 million hectares to 277 million hectares in 2002. In addition, the shift from large dams with gravity-fed canal systems that dominated the last century's third quarter to drilled wells that tap underground water resources has also boosted irrigation fuel use.^^24^^\n\nSome trends, such as the shift to no tillage, are making agriculture less oil-intensive. But rising fertilizer use, the spread of farm mechanization, and falling water tables are making food production more oil-dependent. This helps explain why farmers are becoming involved in the production of biofuels, both ethanol to replace gasoline and biodiesel to replace diesel. (Renewed interest in these fuels is discussed later in this chapter.)\n\nAlthough attention commonly focuses on energy use on the farm, this accounts for only one fifth of total food system energy use in the United States. Transport, processing, packaging, marketing, and kitchen preparation of food account for nearly four fifths of food system energy use. Indeed, my colleague Danielle Murray notes that the U.S. food economy uses as much energy as France does in its entire economy. The 14 percent of energy used in the food system to move goods from farmer to consumer is roughly equal to two thirds of the energy used to produce the food. And an estimated 16 percent of food system energy use is devoted to processing - canning, freezing, and drying food - everything from frozen orange juice concentrate to canned peas.^^26^^\n\nFood staples, such as wheat, have traditionally moved over long distances by ship, traveling from the United States to Europe, for example. What is new is the shipment of fresh fruits and vegetables over vast distances by air. Few economic activities are more energy-intensive.^^27^^\n\nFood miles - the distance food travels from producer to con-sumer - have risen with cheap oil. Among the longest hauls are the flights during the northern hemisphere winter that carry fresh produce, such as blueberries from New Zealand to the United Kingdom. At my local supermarket in downtown Washington, D.C., the fresh grapes in winter typically come by plane from Chile, traveling almost 5,000 miles. Occasionally they come from South Africa, in which case the distance from grape arbor to dining room table is 8,000 miles, nearly a third of the way around the earth.^^28^^\n\nOne of the most routine long-distance movements of fresh produce is from California to the heavily populated U.S. East Coast. Most of this produce moves by refrigerated trucks. In assessing the future of long-distance produce transport, one oil analyst observed that the days of the 3,000-mile Caesar salad may be numbered.^^29^^\n\nPackaging is also surprisingly energy-intensive, accounting for 7 percent of food system energy use. It is not uncommon for the energy invested in packaging to exceed that of the food it contains. And worse, nearly all the packaging in a modern supermarket is designed to be discarded after one use.^^30^^\n\nThe most energy-intensive segment of the food chain is the kitchen. Much more energy is used to refrigerate and prepare food in the home than is used to produce it in the first place. The big energy user in the food system is the kitchen refrigerator, not the farm tractor.^^31^^\n\nWhile the use of oil dominates the production end of the food system, electricity (usually produced from coal or gas) dominates the consumption end. The oil-intensive modern food system that evolved when oil was cheap will not survive as it is now structured with higher energy prices. Among the principal adjustments will be more local food production and movement down the food chain as consumers react to rising food prices by buying fewer high-cost livestock products.\n\n[[2.3 - The Falling Wheat-Oil Exchange Rate]]\n\n[[2.4 - Food and Fuel Compete for Land]]\n\n[[2.5 - Cities and Suburbs After Peak Oil]]\n\n[[2.6 - The World After Oil Peaks]]\n\n[[2.7 - Additional Resources]]\n\n[[2.8 - Notes]]\n\n[[3 - Emerging Water Shortages]]
While we focus on the oil used to produce food, the amount of oil that food will buy is falling precipitously. The shift in terms of trade between wheat and oil is both dramatic and ongoing. From 1950 to 1973, the prices of both wheat and oil were remarkably stable, as was the relationship between the two. At any time during the 23-year span, a bushel of wheat could be traded for a barrel of oil in the world market. (See Table 2-1.)^^32^^\n\nSince 1973, however, the relative values of wheat and oil have shifted dramatically. In 2005, it took 13 bushels of wheat to buy a barrel of oil. The two countries most affected by this dramatic shift are the leading exporters of these two commodities: the United States and Saudi Arabia.^^33^^\n\n<<tiddler Table-2-1>>\n\nThe United States, both the largest importer of oil and the largest exporter of grain, is paying dearly for this shift in the wheat-oil exchange rate. The 13-fold shift since 1973 is contributing to the largest U.S. trade deficit in history and a record external debt. In contrast, Saudi Arabia - the world's leading oil exporter and a leading grain importer - is benefiting handsomely.^^34^^\n\nWhile the exchange rate between grain and oil was deteriorating, U.S. oil imports were climbing. During the early 1970s, before the OPEC oil price hikes, the United States largely could pay its oil import bill with grain exports. But in 2004, grain exports covered only 13 percent of the staggering U.S. oil import bill of $132 billion.^^35^^\n\nThe first big adjustment between oil and wheat came when OPEC tripled the price of oil at the end of 1973. During 1974-78, it took roughly three bushels of wheat to buy a barrel of oil. Then after the second OPEC oil price hike, which boosted oil from $13 per barrel in 1978 to $30 in 1980, it took eight bushels of wheat to buy a barrel of oil.^^36^^\n\nThis steep rise in the buying power of oil led to one of the most abrupt transfers of wealth in history. The coffers of Saudi Arabia, Kuwait, Iraq, and Iran began to overflow with dollars while those of oil-importing countries were being emptied.\n\nNo one knows exactly what will happen to the wheat-oil exchange rate in the years ahead, but as the number of grain-based ethanol distilleries producing automotive fuel grows, the profitability of converting grain into fuel may stabilize the wheat-oil exchange rate.\n\nThe United States is pressing the Saudis to produce more oil. Yet the answer is not for the Saudis to produce more, even if they can, but for the United States to consume less. Unless the United States assumes a leadership role, Saudi Arabia will continue to dictate not only the exchange rate between oil and grain but also U.S. gasoline prices.\n\n[[2.4 - Food and Fuel Compete for Land]]\n\n[[2.5 - Cities and Suburbs After Peak Oil]]\n\n[[2.6 - The World After Oil Peaks]]\n\n[[2.7 - Additional Resources]]\n\n[[2.8 - Notes]]\n\n[[3 - Emerging Water Shortages]]
Historically, the world's farmers produced food, feed, and fiber. Today they are starting to produce fuel as well. Since nearly everything we eat can be converted into automotive fuel, the high price of oil is becoming the support price for farm products. It is also determining the price of food. On any given day there are now two groups of buyers in world commodity markets: one representing food processors and another representing biofuel producers. The line between the food and fuel economies has suddenly blurred as service stations compete with supermarkets for the same commodities.\n\nFirst triggered by the oil shocks of the 1970s, production of biofuels - principally ethanol from sugarcane in Brazil and corn in the United States - grew rapidly for some years but then stagnated during the 1990s. After 2000, as oil prices edged upward, it began to again gain momentum. (See Figure 2-1.) Europe, meanwhile, led by Germany and France, was starting to extract biodiesel from oilseeds.^^37^^\n\nProduction of biofuels in 2005 equaled nearly 2 percent of world gasoline use. From 2000 to 2005, ethanol production worldwide increased from 4.6 billion to 12.2 billion gallons, a jump of 165 percent. Biodiesel, starting from a small base of 251 million gallons in 2000, climbed to an estimated 790 million gallons in 2005, more than tripling.^^38^^\n\nGovernments support biofuel production because of concerns about climate change and a possible shrinkage in the flow of imported oil. Since substituting biofuels for gasoline reduces carbon emissions, governments see this as a way to meet their carbon reduction goals. Biofuels also have a domestic economic appeal partly because locally produced fuel creates jobs and keeps money within the country.\n\n<<tiddler Figure 2-1>>\n\nBrazil, using sugarcane as the feedstock for ethanol, is producing some 4 billion gallons a year, satisfying 40 percent of its automotive fuel needs. The United States, using corn as the feedstock, produced 3.4 billion gallons of ethanol in 2004, supplying just under 2 percent of the fuel used by its vast automotive fleet. Forecasts for 2005 show U.S. ethanol output overtaking that of Brazil, at least temporarily. Europe ranks third in fuel ethanol output, the lion's share from France, the United Kingdom, and Spain. Europe's distillers use mostly sugar beets, wheat, and barley.\n\nInterest in biofuels has escalated sharply since oil prices reached $40 per barrel in mid-2004. Brazil, the world's largest sugarcane producer, is emerging as the world leader in farm fuel production. In 2004, half of its sugarcane crop was used for sugar and half for ethanol. Expanding the sugarcane area from\n\n5.3 million hectares in 2005 to some 8 million hectares would enable it to become self-sufficient in automotive fuel within a matter of years while maintaining its sugar production and exports.^^40^^\n\nEven though Brazil has phased out ethanol subsidies, by mid-2005 the private sector had committed $5.1 billion to investment in sugar mills and distilleries over the next five years. Thinking beyond its currently modest exports of ethanol, Brazil is discussing ethanol supply contracts with Japan and China. Producing ethanol at 60¬Ę per gallon, Brazil is in a strong competitive position in a world with $60-a-barrel oil.^^41^^\n\nU.S. ethanol production, almost entirely from corn, benefits from a government subsidy of 51¬Ę per gallon. Ethanol produced from $3-a-bushel corn in the United States costs roughly $1.40 per gallon, more than twice the cost of Brazil's cane-based ethanol. Although it took roughly a decade to develop the first billion gallons of U.S. distilling capacity and another decade for the second billion, the third billion was added in two years. The fourth billion will likely be added in even less time. In addition to corporations, U.S. farm groups are also investing heavily in ethanol distilleries.^^42^^\n\nIndia, the world's second largest producer of sugarcane, has 10 ethanol plants in operation and expects to have 20 additional plants up and running by the end of 2005. China is projected to bring on-line four plants producing up to 360 million gallons of additional fuel ethanol by the end of 2005, mostly from corn and wheat.^^43^^\n\nColombia and the Central American countries represent the other biofuel hot spot. Colombia is off to a fast start, opening one new ethanol distillery each month from August 2005 through the end of the year. The challenge is to coordinate growth in distillery construction with growth in the land in sugarcane.^^44^^\n\nFor biofuels used in diesel engines, Europe is the leader. Germany, producing 326 million gallons of biodiesel in 2004, is now covering 3 percent of its diesel fuel needs. Relying almost entirely on rapeseed (the principal source of cooking oil in Europe), it plans to expand output by half within the next few years.^^45^^\n\nFrance, where biodiesel production totaled 150 million gallons in 2004, plans to double its output by 2007. Like Germany, it uses rapeseed as its feedstock. In both countries the impetus for biodiesel production comes from the European Union's goal of meeting 5.75 percent of automotive fuel needs with biofuels by 2010. Biofuels in Europe are exempted from the hefty taxes levied on gasoline and diesel.^^46^^\n\nIn the United States, a latecomer to biodiesel production, output is growing rapidly since the 2003 adoption of a $1-per-gallon subsidy that took effect in January 2005. Iowa, a leading soybean producer and a hotbed of soy-fuel enthusiasm, now has three biodiesel plants in operation, another under construction, and five more in the planning stages. State officials estimate that biodiesel plants will be extracting oil from 200 million bushels of the state's 500-million-bushel annual harvest within a few years, producing 280 million gallons of biodiesel. The four fifths of the soybean left after the oil is extracted is a protein-rich livestock feed supplement, which is even more valuable than the oil itself.^^47^^\n\nOther countries either producing biodiesel or planning to do so include Malaysia, Indonesia, and Brazil. Malaysia and Indonesia, the major producers of palm oil, would likely use highly productive oil palm plantations as their feedstock source. Brazil, which has ambitious plans to ramp up biodiesel production, will also likely turn to palm oil.^^48^^\n\nThere are two key indicators in evaluating crops for biofuel production: the fuel yield per acre and the net energy yield of the biofuels, after subtracting the energy used in both production and refining. For ethanol, the top yields per acre are 714 gallons from sugar beets in France and 662 gallons per acre for sugarcane in Brazil. (See Table 2-2.) U.S. corn comes in at 354 gallons per acre, or roughly half the beet and cane yields.^^49^^\n\nWith biodiesel production, oil palm plantations are a strong first, with a yield of 508 gallons per acre. Next comes coconut oil, with 230 gallons per acre, and rapeseed, at 102 gallons per acre. Soybeans, grown primarily for their protein content, yield only 56 gallons per acre.^^50^^\n\nFor net energy yield, ethanol from sugarcane in Brazil is in a class all by itself, yielding over 8 units of energy for each unit invested in cane production and ethanol distillation. Once the sugary syrup is removed from the cane, the fibrous remainder, bagasse, is burned to provide the heat needed for distillation, eliminating the need for an additional external energy source. This helps explain why Brazil can produce cane-based ethanol for 60¬Ę per gallon.^^51^^\n\n<<tiddler Table-2-1>>\nEthanol from sugar beets in France comes in at 1.9 energy units for each unit of invested energy. Among the three principal feedstocks now used for ethanol production, U.S. corn-based ethanol, which relies largely on natural gas for distillation energy, comes in a distant third in net energy efficiency, yielding only 1.5 units of energy for each energy unit used.^^52^^\n\nAnother perhaps more promising option for producing ethanol is to use enzymes to break down cellulosic materials, such as switchgrass, a vigorously growing perennial grass, or fast-growing trees, such as hybrid poplars. Ethanol is now being produced from cellulose in a small demonstration plant in Canada. If switchgrass turns out to be an economic source of ethanol, as some analysts think it may, it will be a major breakthrough, since it can be grown on land that is highly erodible or otherwise not suitable for annual crops. In a competitive world market for crop-based ethanol, the future belongs to sugarcane and switchgrass.^^53^^\n\nThe ethanol yield per acre for switchgrass is calculated at 1,150 gallons, higher even than for sugarcane. The net energy yield, however, is roughly 4, far above the 1.5 for corn but less than the 8 for sugarcane.^^54^^\n\nAside from the prospective use of cellulose, current and planned ethanol-producing operations use food crops such as sugarcane, sugar beets, corn, wheat, and barley. The United States, for example, in 2004 used 32 million tons of corn to produce 3.4 billion gallons of ethanol. Although this is scarcely 12 percent of the huge U.S. corn crop, it is enough to feed 100 million people at average world grain consumption levels.^^55^^\n\nIn an oil-short world, what will be the economic and environmental effects of agriculture's emergence as a producer of transport fuels? Agriculture's role in the global economy clearly will be strengthened as it faces a vast, virtually unlimited market for automotive fuel. Tropical and subtropical countries that can produce sugarcane or palm oil will be able to fully exploit their year-round growing conditions, giving them a strong comparative advantage in the world market.\n\nWith biofuel production spreading, the world price for oil will, in effect, become a support price for farm products. If food and feed crop prices are weak and oil prices are high, commodities will go to fuel producers. For example, vegetable oils trading on European markets on any given day may end up in either supermarkets or service stations.\n\nThe risk is that economic pressures to clear land for expanding sugarcane production in the Brazilian //cerrado// and Amazon basin and for palm oil plantations in countries such as Indonesia and Malaysia will pose a major new threat to plant and animal diversity. In the absence of governmental constraints, the rising price of oil could quickly become the leading threat to biodiversity, ensuring that the wave of extinctions now under way does indeed become the sixth great extinction.\n\nWith oil prices now high enough to stimulate potentially massive investments in fuel crop production, the world farm economy - already struggling to feed 6.5 billion people - will face far greater demands. How the world manages this new incredibly complex situation will tell us a great deal about the prospect for our energy-hungry twenty-first century civilization.^^56^^\n\n[[2.5 - Cities and Suburbs After Peak Oil]]\n\n[[2.6 - The World After Oil Peaks]]\n\n[[2.7 - Additional Resources]]\n\n[[2.8 - Notes]]\n\n[[3 - Emerging Water Shortages]]
Modern cities are a product of the oil age. From the first cities, which apparently took shape in Mesopotamia some 6,000 years ago, until 1900, urbanization was a slow, barely perceptible process. When the last century began, there were only a few cities with a million people. Today there are more than 400 cities that large, and 20 mega-cities have 10 million or more residents.^^57^^\n\nThe metabolism of cities depends on concentrating vast amounts of food and materials and then disposing of garbage and human waste. With the limited range and capacity of horse-drawn wagons, it was difficult to create large cities. Trucks running on cheap oil changed all that.\n\nAs cities grow ever larger and as nearby landfills reach capacity, garbage must be hauled longer distances to disposal sites. With oil prices rising and available landfills receding ever further from the city, the cost of garbage disposal also rises. At some point, many throwaway products may be priced out of existence.\n\nUrban living costs will likely rise as oil production turns down and oil prices escalate. One of the intriguing questions this raises is whether urbanization will continue APO, after peak oil. Or might the process even be reversed when people seek less oil-dependent lifestyles?\n\nCities will be hard hit by the coming decline in oil production, but suburbs will be hit even harder. People living in poorly designed suburbs not only depend on importing everything, they are also often isolated geographically from their jobs and shops. They must drive for virtually everything they need. Living in suburban housing developments often means using a car even to get a loaf of bread or a quart of milk.\n\nSuburbs have created a commuter culture, with the daily roundtrip commute taking, on average, close to an hour a day in the United States. While Europe's cities were largely mature before the onslaught of the automobile, those in the United States, a much younger country, were shaped by the car. While city limits are usually rather clearly defined in Europe, and while Europeans only reluctantly convert productive farmland into housing developments, Americans have few qualms about this because of a frontier mentality and because cropland was long seen as a surplus commodity.\n\nThis unsightly, aesthetically incongruous sprawl of suburbs and strip malls is not limited to the United States. It is found in Latin America, in Southeast Asia, and increasingly in China. Flying from Shanghai to Beijing provides a good view of the sprawl of buildings, including homes and factories, that is following the new roads and highways. This is in sharp contrast to the tightly built villages that shaped residential land use for millennia in China.\n\nShopping malls and huge discount stores, symbolized in the public mind by WalMart, were all subsidized by artificially cheap oil. Isolated by high oil prices, suburbs may prove to be ecologically and economically unsustainable. Thomas Wheeler, editor of the //Alternative Press Review//, observes that "there will eventually be a great scramble to get out of the suburbs as the world oil crisis deepens and the property values of suburban homes plummet."^^58^^\n\n[[2.6 - The World After Oil Peaks]]\n\n[[2.7 - Additional Resources]]\n\n[[2.8 - Notes]]\n\n[[3 - Emerging Water Shortages]]
Peak oil is described as the point where oil production stops rising and begins its unavoidable long-term decline. In the face of fast-growing demand, this means rising oil prices. But even if oil production growth simply slows or plateaus, the resulting tightening in supplies will still drive the price of oil upward, albeit less rapidly.\n\nFew countries are planning a reduction in their use of oil. Indeed, the projections of oil use by both the International Energy Agency and the U.S. Department of Energy show world oil consumption going from roughly 84 million barrels a day at present to 120 million barrels a day by 2030. According to these analyses, oil consumption in individual countries will be increasing on average by nearly half over the next 20 years. How did they come up with these "rosy" forecasts? To quote Thomas Wheeler again, are many analysts and leaders simply "oblivious to the flashing red light on the earth's fuel gauge?"^^59^^\n\nEven though peak oil may be imminent, most countries are counting on much higher oil consumption in the decades ahead. Indeed, they are building automobile assembly plants, roads, highways, parking lots, and suburban housing developments as though cheap oil will last forever. New airliners are being delivered with the expectation that air travel and freight will expand indefinitely. Yet in a world of declining oil production, no country can use more oil except at the expense of others.^^60^^\n\nSome segments of the global economy will be affected more than others simply because some are more oil-intensive. Among these are the automobile, food, and airline industries. Stresses within the U.S. auto industry were already evident before oil prices started climbing in mid-2004. Now General Motors and Ford, both trapped with their heavy reliance on sales of gas-hogging sport utility vehicles, have seen Standard and Poors lower their credit ratings, reducing their corporate bonds to junk bond status. In June 2005, General Motors announced that it planned to cut its U.S. workforce of 110,000 by 25,000 workers in 2007.^^61^^\n\nAlthough it is the troubled automobile manufacturers that appear in the headlines as oil prices rise, their affiliated industries will also be affected, including auto parts and tire manufacturers.\n\nThe food sector will be affected in two ways. Food will become more costly as higher oil prices drive up production costs. As oil costs rise, diets will be altered as people move down the food chain and as they consume more local, seasonally produced food. Diets will thus become more closely attuned to local products and more seasonal in nature.\n\nAt the same time, rising oil prices will also be drawing agricultural resources into the production of fuel crops, either ethanol or biodiesel. Higher oil prices are thus setting up competition between affluent motorists and low-income food consumers for food resources, presenting the world with a complex new ethical issue.\n\nAirlines, both passenger travel and freight, will continue to suffer as jet fuel prices climb, simply because fuel is their biggest operating expense. Although industry projections show air passenger travel growing by some 5 percent a year for the next decade, this seems highly unlikely. Cheap airfares may soon become history.\n\nAir freight may be hit even harder, perhaps leading to an absolute decline. One of the early casualties of rising oil prices could be the use of jumbo jets to transport fresh produce from the southern hemisphere to industrial countries during the northern winter. The price of fresh produce out of season may simply become prohibitive.\n\nDuring the century of cheap oil, an enormous automobile infrastructure was built in industrial countries that requires large amounts of energy to maintain. The United States, for example, has 2.6 million miles of paved roads, covered mostly with asphalt, and 1.4 million miles of unpaved roads to maintain even if world oil production is falling. Higher energy prices may create a maintenance crisis.^^63^^\n\nIn addition to needing to use oil more efficiently, the world is also looking to other sources of energy. Although nuclear power has been getting some press attention as an alternative to fossil fuels, electricity from nuclear power plants is costly. On a level playing field with no taxpayer subsidies, nuclear power is dead. If utilities pay the full costs of nuclear waste disposal, of insurance against an accident, and of decommissioning plants that are worn out, the expense of nuclear power will take it out of the running. And with international terrorism on the rise, the vulnerability of nuclear power plants to attack combined with their use by countries as a steppingstone to the acquisition of nuclear weapons virtually eliminates nuclear fission as a future energy source.^^64^^\n\nThe relative abundance of coal makes it an attractive energy source in some quarters, but it is likely to soon become a victim of mounting public concern about climate change. This means a future of renewable sources of energy, including wind energy, solar cells, solar thermal panels, solar thermal power plants, geothermal energy, hydropower, wave power, and biofuels.\n\nIn the coming energy transition, there will be winners and losers. Countries that fail to plan ahead, that lag in investing in more oil-efficient technologies and new energy sources, may experience a decline in living standards. The inability of national governments to manage the energy transition could lead to a failure of confidence in leaders and to failed states.\n\nNational political leaders seem reluctant to face the coming downturn in oil and to plan for it even though it will become one of the great fault lines not only in recent economic history but in the history of civilization. Trends now taken for granted, such as urbanization and globalization, could be reversed almost overnight as oil becomes scarce and costly.\n\nDeveloping countries will be hit doubly hard as still-expanding populations combine with a shrinking oil supply to steadily reduce oil use per person. Such a decline could quickly translate into a fall in living standards. If the United States, the world's largest oil consumer and importer, can sharply reduce its use of oil, it can buy the world time for a smoother transition to the post-petroleum era. What the world needs today is not more oil, but more leadership.\n\n[[2.7 - Additional Resources]]\n\n[[2.8 - Notes]]\n\n[[3 - Emerging Water Shortages]]

Africa's Lake Chad, once a landmark for astronauts circling the earth, is now difficult for them to locate. Surrounded by Chad, Niger, and Nigeria - three countries with some of the world's fastest-growing populations - the lake has shrunk by 95 percent since the 1960s. The soaring demand for irrigation water in that area is draining dry the rivers and streams the lake depends on for its existence. As a result, Lake Chad may soon disappear entirely, its whereabouts a mystery to future generations.^^1^^\n\nEvery day, it seems, we read about lakes disappearing, wells going dry, or rivers failing to reach the sea. But these stories typically describe local situations. It is not until we begin to compile the numerous national studies - such as an 824-page analysis of the water situation in China, a World Bank study of the water situation in Yemen, or a detailed U.S. Department of Agriculture (USDA) assessment of the irrigation prospect in the western United States - that the extent of emerging water shortages worldwide can be grasped. Only then can we see the extent of water overuse and the decline it can bring.^^2^^\n\nThe world is incurring a vast water deficit - one that is largely invisible, historically recent, and growing fast. Because much of the deficit comes from aquifer overpumping, it is often not apparent. Unlike burning forests or invading sand dunes, falling water tables are often discovered only when wells go dry.\n\nThis global water deficit is recent, the result of demand tripling over the last half-century. The drilling of millions of irrigation wells has pushed water withdrawals beyond the recharge of many aquifers. The failure of governments to limit pumping to the sustainable yield of aquifers means that water tables are now falling in countries that contain more than half the world's people.^^3^^\n\nAmong the more visible manifestations of water scarcity are rivers running dry and lakes disappearing. A politics of water scarcity is emerging between upstream and downstream claimants both within and among countries. Water scarcity is now crossing borders via the international grain trade. Countries that are pressing against the limits of their water supply typically satisfy the growing need of cities and industry by diverting irrigation water from agriculture, and then importing grain to offset the loss of productive capacity.\n\nThe link between water and food is strong. We each drink on average nearly 4 liters of water per day in one form or another, while the water required to produce our daily food totals at least 2,000 liters - 500 times as much. This helps explain why 70 percent of all water use is for one purpose - irrigation. Another 20 percent is used by industry, and 10 percent goes for residential purposes. With the demand for water growing in all three categories, competition among sectors is intensifying, with farmers almost always losing.^^4^^\n\n[[3.1 - Falling Water Tables]]\n\n[[3.2 - Rivers Running Dry]]\n\n[[3.3 - Disappearing Lakes]]\n\n[[3.4 - Farmers Losing to Cities]]\n\n[[3.5 - Scarcity Crossing National Borders]]\n\n[[3.6 - A Food Bubble Economy]]\n\n[[3.7 - Additional Resources]]\n\n[[3.8 - Notes]]\n\n[[4 - Rising Temperatures and Rising Seas]]\n\n----\nDownload pdf version of Chapter 3\n\n 18pp. (72 Kb)
Scores of countries are overpumping aquifers as they struggle to satisfy their growing water needs, including each of the big three grain producers - China, India, and the United States. These three, along with a number of other countries where water tables are falling, are home to more than half the world's people. (See Table 3-1.)^^5^^\n\nThere are two types of aquifers: replenishable and nonreplenishable (or fossil) aquifers. Most of the aquifers in India and the shallow aquifer under the North China Plain are replenishable. When these are depleted, the maximum rate of pumping is automatically reduced to the rate of recharge.\n\n<<tiddler Table 3-1>>\n\nFor fossil aquifers, such as the vast U.S. Ogallala aquifer, the deep aquifer under the North China Plain, or the Saudi aquifer, depletion brings pumping to an end. Farmers who lose their irrigation water have the option of returning to lower-yield dryland farming if rainfall permits. In more arid regions, however, such as in the southwestern United States or the Middle East, the loss of irrigation water means the end of agriculture.\n\nFalling water tables are already adversely affecting harvests in some countries, including China, the world's largest grain producer. A groundwater survey released in Beijing in August 2001 revealed that the water table under the North China Plain, which produces over half of that country's wheat and a third of its corn, is falling faster than earlier reported. Overpumping has largely depleted the shallow aquifer, forcing well drillers to turn to the region's deep fossil aquifer, which is not replenishable.^^6^^\n\nThe survey, conducted by the Geological Environmental Monitoring Institute (GEMI) in Beijing, reported that under Hebei Province in the heart of the North China Plain, the average level of the deep aquifer was dropping nearly 3 meters (10 feet) per year. Around some cities in the province, it was falling twice as fast. He Qingcheng, head of the GEMI groundwater monitoring team, notes that as the deep aquifer is depleted, the region is losing its last water reserve - its only safety cushion.^^7^^\n\nHis concerns are mirrored in a World Bank report: "Anecdotal evidence suggests that deep wells [drilled] around Beijing now have to reach 1,000 meters [more than half a mile] to tap fresh water, adding dramatically to the cost of supply." In unusually strong language for a Bank report, it foresees "catastrophic consequences for future generations" unless water use and supply can quickly be brought back into balance.^^8^^\n\nThe U.S. embassy in Beijing reports that wheat farmers in some areas are now pumping from a depth of 300 meters, or nearly 1,000 feet. Pumping water from this far down raises pumping costs so high that farmers are often forced to abandon irrigation and return to less productive dryland farming.^^9^^\n\nFalling water tables, the conversion of cropland to nonfarm uses, and the loss of farm labor in provinces that are rapidly industrializing are combining to shrink China's grain harvest. The wheat crop, grown mostly in semiarid northern China, is particularly vulnerable to water shortages. After peaking at 123 million tons in 1997, the harvest has fallen in five of the last eight years, coming in at 95 million tons in 2005, a drop of 23 percent.^^10^^\n\nThe U.S. embassy also reports that the recent decline in rice production is partly a result of water shortages. After peaking at 140 million tons in 1997, the harvest dropped in four of the following eight years, falling to an estimated 127 million tons in 2005. Only corn, China's third major grain, has thus far avoided a decline. This is because corn prices are favorable and because the crop is not as irrigation-dependent as wheat and rice are.^^11^^\n\nOverall, China's grain production has fallen from its historical peak of 392 million tons in 1998 to an estimated 358 million tons in 2005. For perspective, this drop of 34 million tons exceeds the annual Canadian wheat harvest. China largely covered the drop-off in production by drawing down its once vast stocks until 2004, at which point it imported 7 million tons of grain.^^12^^\n\nA World Bank study indicates that China is overpumping three river basins in the north - the Hai, which flows through Beijing and Tianjin; the Yellow; and the Huai, the next river south of the Yellow. Since it takes 1,000 tons of water to produce one ton of grain, the shortfall in the Hai basin of nearly 40 billion tons of water per year (1 ton equals 1 cubic meter) means that when the aquifer is depleted, the grain harvest will drop by 40 million tons - enough to feed 120 million Chinese.^^13^^\n\nOf the leading grain producers, only China has thus far experienced a substantial decline in production. Even with a worldwide grain crunch and climbing grain prices providing an incentive to boost production, it will be difficult for China to regain earlier grain production levels, given the loss of irrigation water.^^14^^\n\nSerious though emerging water shortages are in China, they are even more serious in India simply because the margin between actual food consumption and survival is so precarious. In a survey of India's water situation, Fred Pearce reported in the //New Scientist// that the 21 million wells drilled in this global epicenter of well-drilling are lowering water tables in most of the country. In North Gujarat, the water table is falling by 6 meters (20 feet) per year.^^15^^\n\nIn Tamil Nadu, a state with more than 62 million people in southern India, wells are going dry almost everywhere. According to Kuppannan Palanisami of Tamil Nadu Agricultural University, falling water tables have dried up 95 percent of the wells owned by small farmers, reducing the irrigated area in the state by half over the last decade.^^16^^\n\nAs water tables fall, well drillers are using modified oil-drilling technology to reach water, going as deep as 1,000 meters in some locations. In communities where underground water sources have dried up entirely, all agriculture is rain-fed and drinking water is trucked in. Tushaar Shah, who heads the International Water Management Institute's groundwater station in Gujarat, says of India's water situation, "When the balloon bursts, untold anarchy will be the lot of rural India."^^17^^\n\nAt this point, the harvests of wheat and rice, India's principal food grains, are still increasing. But within the next few years, the loss of irrigation water could override technological progress and start shrinking the harvest in some areas, as it is already doing in China.^^18^^\n\nIn the United States, the USDA reports that in parts of Texas, Oklahoma, and Kansas - three leading grain-producing states - the underground water table has dropped by more than 30 meters (100 feet). As a result, wells have gone dry on thousands of farms in the southern Great Plains. Although this mining of underground water is taking a toll on U.S. grain production, irrigated land accounts for only one fifth of the U.S. grain harvest, compared with close to three fifths of the harvest in India and four fifths in China.^^19^^\n\nPakistan, a country with 158 million people that is growing by 3 million per year, is also mining its underground water. In the Pakistani part of the fertile Punjab plain, the drop in water tables appears to be similar to that in India. Observation wells near the twin cities of Islamabad and Rawalpindi show a fall in the water table between 1982 and 2000 that ranges from 1 to nearly 2 meters a year.^^20^^\n\nIn the province of Baluchistan, water tables around the capital, Quetta, are falling by 3.5 meters per year. Richard Garstang, a water expert with the World Wildlife Fund and a participant in a study of Pakistan's water situation, said in 2001 that "within 15 years Quetta will run out of water if the current consumption rate continues."^^21^^\n\nThe water shortage in Baluchistan is province-wide. Sardar Riaz A. Khan, former director of Pakistan's Arid Zone Research Institute in Quetta, reports that six basins have exhausted their groundwater supplies, leaving their irrigated lands barren. Khan expects that within 10-15 years virtually all the basins outside the canal-irrigated areas will have depleted their groundwater supplies, depriving the province of much of its grain harvest.^^22^^\n\nFuture irrigation water cutbacks as a result of aquifer depletion will undoubtedly reduce Pakistan's grain harvest. Countrywide, the harvest of wheat - the principal food staple - is continuing to grow, but more slowly than in the past.^^23^^\n\nIran, a country of 70 million people, is overpumping its aquifers by an average of 5 billion tons of water per year, the water equivalent of one third of its annual grain harvest. Under the small but agriculturally rich Chenaran Plain in northeastern Iran, the water table was falling by 2.8 meters a year in the late 1990s. New wells being drilled both for irrigation and to supply the nearby city of Mashad are responsible. Villages in eastern Iran are being abandoned as wells go dry, generating a flow of "water refugees."^^24^^\n\nSaudi Arabia, a country of 25 million people, is as water-poor as it is oil-rich. Relying heavily on subsidies, it developed an extensive irrigated agriculture based largely on its deep fossil aquifer. After several years of using oil money to support wheat prices at five times the world market level, the government was forced to face fiscal reality and cut the subsidies. Its wheat harvest dropped from a high of 4.1 million tons in 1992 to 1.2 million tons in 2005, a drop of 71 percent.^^25^^\n\nCraig Smith writes in the //New York Times//, "From the air, the circular wheat fields of this arid land's breadbasket look like forest green poker chips strewn across the brown desert. But they are outnumbered by the ghostly silhouettes of fields left to fade back into the sand, places where the kingdom's gamble on agriculture has sucked precious aquifers dry." Some Saudi farmers are now pumping water from wells that are 4,000 feet deep, nearly four fifths of a mile (1 mile equals 1.61 kilometers).^^26^^\n\nA 1984 Saudi national survey reported fossil water reserves at 462 billion tons. Half of that, Smith reports, has probably disappeared by now. This suggests that irrigated agriculture could last for another decade or so and then will largely vanish, limited to the small area that can be irrigated with water from the shallow aquifers that are replenished by the kingdom's sparse rainfall. It is a classic example of an overshoot-and-collapse food economy.^^27^^\n\nIn neighboring Yemen, a nation of 21 million, the water table under most of the country is falling by roughly 2 meters a year as water use outstrips the sustainable yield of aquifers. In western Yemen's Sana'a Basin, the estimated annual water extraction of 224 million tons exceeds the annual recharge of 42 million tons by a factor of five, dropping the water table 6 meters per year. World Bank projections indicate the Sana'a Basin - site of the national capital, Sana'a, and home to 2 million people - will be pumped dry by 2010.^^28^^\n\nIn the search for water, the Yemeni government has drilled test wells in the basin that are 2 kilometers (1.2 miles) deep - depths normally associated with the oil industry - but they have failed to find water. Yemen must soon decide whether to bring water to Sana'a, possibly by pipeline from coastal desalting plants, if it can afford it, or to relocate the capital. Either alternative will be costly and potentially traumatic.^^29^^\n\nWith its population growing at 3 percent a year and with water tables falling everywhere, Yemen is fast becoming a hydrological basket case. Aside from the effect of overpumping on the capital, World Bank official Christopher Ward observes that "groundwater is being mined at such a rate that parts of the rural economy could disappear within a generation."^^30^^\n\nIsrael, even though it is a pioneer in raising irrigation water productivity, is depleting both of its principal aquifers - the coastal aquifer and the mountain aquifer that it shares with Palestinians. Israel's population, whose growth is fueled by both natural increase and immigration, is outgrowing its water supply. Conflicts between Israelis and Palestinians over the allocation of water in the latter area are ongoing. Because of severe water shortages, Israel has banned the irrigation of wheat.^^31^^\n\nIn Mexico - home to a population of 107 million that is projected to reach 140 million by 2050 - the demand for water is outstripping supply. Mexico City's water problems are well known. Rural areas are also suffering. For example, in the agricultural state of Guanajuato, the water table is falling by 2 meters or more a year. At the national level, 51 percent of all the water extracted from underground is from aquifers that are being overpumped.^^32^^\n\nSince the overpumping of aquifers is occurring in many countries more or less simultaneously, the depletion of aquifers and the resulting harvest cutbacks could come at roughly the same time. And the accelerating depletion of aquifers means this day may come soon, creating potentially unmanageable food scarcity.\n\n[[3.2 - Rivers Running Dry]]\n\n[[3.3 - Disappearing Lakes]]\n\n[[3.4 - Farmers Losing to Cities]]\n\n[[3.5 - Scarcity Crossing National Borders]]\n\n[[3.6 - A Food Bubble Economy]]\n\n[[3.7 - Additional Resources]]\n\n[[3.8 - Notes]]\n\n[[4 - Rising Temperatures and Rising Seas]]
While falling water tables are largely hidden, rivers that are drained dry before they reach the sea are highly visible. Two rivers where this phenomenon can be seen are the Colorado, the major river in the southwestern United States, and the Yellow, the largest river in northern China. Other large rivers that either run dry or are reduced to a mere trickle during the dry season are the Nile, the lifeline of Egypt; the Indus, which supplies most of Pakistan's irrigation water; and the Ganges in India's densely populated Gangetic basin. Many smaller rivers have disappeared entirely.^^33^^\n\nAs the world's demand for water has tripled over the last half-century and as the demand for hydroelectric power has grown even faster, dams and diversions of river water have drained many rivers dry. As water tables have fallen, the springs that feed rivers have gone dry, reducing river flows.^^34^^\n\nSince 1950, the number of large dams, those over 15 meters high, has increased from 5,000 to 45,000. Each dam deprives a river of some of its flow. Engineers like to say that dams built to generate electricity do not take water from the river, only its energy, but this is not entirely true since reservoirs increase evaporation. The annual loss of water from a reservoir in arid or semiarid regions, where evaporation rates are high, is typically equal to 10 percent of its storage capacity.\n\nThe Colorado River now rarely makes it to the sea. With the states of Colorado, Utah, Arizona, Nevada, and, most important, California depending heavily on the Colorado's water, the river is simply drained dry before it reaches the Gulf of California. This excessive demand for water is destroying the river's ecosystem, including its fisheries.^^36^^\n\nA similar situation exists in Central Asia. The Amu Darya - which, along with the Syr Darya, feeds the Aral Sea - is now drained dry by Uzbek and Turkmen cotton farmers upstream. With the flow of the Amu Darya cut off, only the diminished flow of the Syr Darya keeps the Aral Sea from disappearing entirely.\n\nChina's Yellow River, which flows some 4,000 kilometers through five provinces before it reaches the Yellow Sea, has been under mounting pressure for several decades. It first ran dry in 1972, and since 1985 it has often failed to reach the sea.^^38^^\n\nThe Nile, site of another ancient civilization, now barely makes it to the sea. Water analyst Sandra Postel, in //Pillar of Sand//, notes that before the Aswan Dam was built, some 32 billion cubic meters of water reached the Mediterranean each year.\n\nAfter the dam was completed, however, increasing irrigation, evaporation, and other demands reduced its discharge to less than 2 billion cubic meters.^^39^^\n\nPakistan, like Egypt, is essentially a river-based civilization, heavily dependent on the Indus. This river, originating in the Himalayas and flowing westward to the Indian Ocean, not only provides surface water, it also recharges aquifers that supply the irrigation wells dotting the Pakistani countryside. In the face of growing water demand, it too is starting to run dry in its lower reaches. Pakistan, with a population projected to reach 305 million by 2050, is in trouble.^^40^^\n\nIn Southeast Asia, the flow of the Mekong is being reduced by the dams being built on its upper reaches by the Chinese. The downstream countries, including Cambodia, Laos, Thailand, and Viet Nam - countries with 168 million people - complain about the reduced flow of the Mekong, but this has done little to curb China's efforts to exploit the power and the water in the river.^^41^^\n\nThe same problem exists with the Tigris and Euphrates Rivers, which originate in Turkey and flow through Syria and Iraq en route to the Persian Gulf. This river system, the site of Sumer and other early civilizations, is being overused. Large dams erected in Turkey and Iraq have reduced water flow to the once "fertile crescent," helping to destroy more than 90 percent of the formerly vast wetlands that enriched the delta region.^^42^^\n\nIn the river systems just mentioned, virtually all the water in the basin is being used. Inevitably, if people upstream get more water, those downstream will get less.\n\n[[3.3 - Disappearing Lakes]]\n\n[[3.4 - Farmers Losing to Cities]]\n\n[[3.5 - Scarcity Crossing National Borders]]\n\n[[3.6 - A Food Bubble Economy]]\n\n[[3.7 - Additional Resources]]\n\n[[3.8 - Notes]]\n\n[[4 - Rising Temperatures and Rising Seas]]
As river flows are reduced or even eliminated entirely and as water tables fall from overpumping, lakes are shrinking and in some cases disappearing. As my colleague Janet Larsen notes, the lakes that are disappearing are some of the world's best known - including Lake Chad in Central Africa, the Aral Sea in Central Asia, and the Sea of Galilee (also known as Lake Tiberias).^^43^^\n\nMany U.S. lakes have not fared well either. In California, Owens Lake, which covered 200 square miles when the last century began, has disappeared. After the Owens River was diverted to thirsty Los Angeles in 1913, the lake lasted little more than a decade.^^44^^\n\nCalifornia's Mono Lake, geologically the oldest lake in North America and a popular feeding stop for migratory water birds, is a more recent victim of Los Angeles's seemingly unquenchable thirst. Mono Lake has experienced a 35-foot drop in its water level since 1941, when the diversion of water from its tributaries to Los Angeles began.^^45^^\n\nReuters reporter Megan Goldin writes that "walking on the Sea of Galilee is a feat a mere mortal can accomplish," due to receding shores. When I first saw the Jordan River as it enters Israel from Syria, its frailty was obvious. Indeed, in many countries it would be called a creek or a stream. And yet it has the primary responsibility for supplying water to the Sea of Galilee, which it enters at the north end and exits on the south end, continuing southward some 105 kilometers before emptying into the Dead Sea.^^46^^\n\nWith the Jordan's flow further diminished as it passes through Israel, the Dead Sea is shrinking even faster than the Sea of Galilee. Over the past 40 years, its water level has dropped by some 25 meters (nearly 80 feet). As a result of diversions from the Jordan River as it flows southward in Israel as well as fast-falling water tables on the Jordanian side, the Dead Sea could disappear entirely by 2050.^^47^^\n\nOf all the shrinking lakes and inland seas, none has gotten as much attention as the Aral Sea. Its ports, once centers of commerce in the region, are now abandoned, looking like the ghost mining towns of the American West. Once one of the world's largest freshwater bodies, the Aral has lost four fifths of its volume since 1960. Ships that once plied its water routes are now stranded in the sand of the old seabed - with no water in sight.^^48^^\n\nThe seeds for the Aral Sea's demise were sown in 1960, when Soviet central planners in Moscow decided the region embracing the Syr Darya and Amu Darya basins would become a vast cotton bowl to supply the country's textile industry. As cotton planting expanded, so too did the diversion of water from the two rivers that fed the Aral Sea. As the sea shrank, the salt concentrations climbed until the fish died. The thriving fishery that once produced 50,000 tons per year disappeared, as did the jobs on the fishing boats and in the fish processing factories.^^49^^\n\nWith the 65-billion-cubic-meter annual influx of water from the two rivers now down to 1.5 billion cubic meters a year, the prospect for reversing the shrinkage is not good. With the sea's shoreline now up to 250 kilometers (165 miles) from the original port cities, there is a vast area of exposed seabed. Each day the wind lifts thousands of tons of sand and salt from the dry seabed, distributing the airborne particles on the surrounding grasslands and croplands and damaging them.^^50^^\n\nAt a 1990 Soviet Academy of Sciences conference on the future of the Aral Sea, there was an aerial tour for foreign guests. Flying over this area in a World War II-vintage single-engine biplane a few hundred feet above the dry, salt-covered seabed, I noted that it looked like the surface of the moon. There was no vegetation, no sign of any life, only total desolation.^^51^^\n\nThe disappearance of lakes is perhaps most pronounced in China. In western China's Qinhai province, through which the Yellow River's main stream flows, there were once 4,077 lakes. Over the last 20 years, more than 2,000 have disappeared. The situation is far worse in Hebei Province, which surrounds Beijing. With water tables falling fast throughout this region, Hebei has lost 969 of its 1,052 lakes.^^52^^\n\nLakes are disappearing in other Asian countries as well, including India, Pakistan, and Iran. For example, numerous lakes have disappeared in India's Kashmir Valley. Lake Dal, at one time covering 75 square kilometers, has shrunk to 12 square kilometers. With water tables falling in so much of India, many lakes are disappearing and others are shrinking fast.^^53^^\n\nPopulation is also outgrowing the water supply in Mexico. Lake Chapala, the country's largest, is the primary source of water for Guadalajara, which is home to 5 million people. Expanding irrigation in the region has reduced water volume in the lake by 80 percent.^^54^^\n\nLakes are disappearing on every continent and for the same reasons: excessive diversion of water from rivers and overpumping of aquifers. No one knows exactly how many lakes have disappeared over the last half-century, but we do know that thousands of them now exist only on old maps.\n\n[[3.4 - Farmers Losing to Cities]]\n\n[[3.5 - Scarcity Crossing National Borders]]\n\n[[3.6 - A Food Bubble Economy]]\n\n[[3.7 - Additional Resources]]\n\n[[3.8 - Notes]]\n\n[[4 - Rising Temperatures and Rising Seas]]
Water conflicts among countries dominate the headlines. But within countries it is the jousting for water between cities and farms that preoccupies local political leaders. The economics of water use do not favor farmers in this competition, simply because it takes so much water to produce food. For example, while it takes only 14 tons of water to make a ton of steel worth $550, it takes 1,000 tons of water to grow a ton of wheat worth $150. In countries preoccupied with expanding the economy and creating jobs, the policy decision to make agriculture the residual claimant comes as no surprise.^^55^^\n\nMany of the world's largest cities are located in watersheds where all available water is being used. Cities in such watersheds, such as Mexico City, Cairo, and Beijing, can increase their water consumption only by importing water from other basins or taking it from agriculture. Literally hundreds of the world's cities are now meeting their growing needs by taking irrigation water from farmers. Among the U.S. cities doing so are San Diego, Los Angeles, Las Vegas, Denver, and El Paso. A USDA study of 11 western states found that annual sales of water rights during 1996 and 1997 averaged 1.65 billion tons, enough to produce 1.65 million tons of grain.^^56^^\n\nWorld Bank calculations for densely populated South Korea, a relatively well watered country, indicate that growth in residential and industrial water use there could reduce the supply available for agriculture from 13 billion to 7 billion tons in 2025. The Bank also projects that between 2000 and 2010, China's urban water demand will increase from 50 billion to 80 billion tons, a growth of 60 percent. Industrial water demand, meanwhile, will go from 127 billion to 206 billion tons, up 62 percent. Several hundred cities are looking to the countryside to satisfy their future water needs. In the region around Beijing, this shift has been under way since 1994, when farmers were banned from drawing on the reservoirs that supplied the city.\n\nAs China attempts to accelerate the economic development of the upper Yellow River basin, emerging industries upstream get priority in the use of water. And as more water is used upstream, less reaches farmers downstream. In unusually dry years, the Yellow River fails to reach Shandong, the last province en route to the sea.^^58^^\n\nFarmers in Shandong, who have traditionally received roughly half of their irrigation water from the Yellow River and half from wells, are now losing water from both sources. Irrigation water losses in a province that produces one fifth of China's corn and one seventh of its wheat help explain why China's grain harvest is declining.^^59^^\n\nLiterally hundreds of cities in other countries are meeting their growing water needs by taking some of the water that farmers count on. In western Turkey, for example, the city of Izmir now relies heavily on well fields from the neighboring agricultural district of Manisa.^^60^^\n\nIn the U.S. southern Great Plains and Southwest, where virtually all water is now spoken for, the growing water needs of cities and thousands of small towns can be satisfied only by taking water from agriculture. A monthly magazine from California, //The Water Strategist//, devotes several pages to a listing of water sales in the western United States during the preceding month. Scarcely a day goes by without another sale. Eight out of 10 sales are typically by either individual farmers or their irrigation districts to cities and municipalities.^^61^^\n\nColorado, with a fast-growing population, has one of the world's most active water markets. Growing cities and towns of all sizes in a state with high immigration are buying irrigation water rights from farmers and ranchers. In the upper Arkansas River basin, which occupies the southeastern quarter of the state, Colorado Springs and Aurora (a suburb of Denver) have already bought water rights to one third of the basin's farmland. Aurora has purchased rights to water that was once used to irrigate 9,600 hectares (23,000 acres) of cropland in the Arkansas valley.\n\nFar larger purchases are being made by cities in California. In 2003, San Diego bought annual rights to 247 million tons (200,000 acre-feet) of water from farmers in the nearby Imperial Valley - the largest rural/urban water transfer in U.S. history. This agreement covers the next 75 years. In 2004, the Metropolitan Water District, which supplies water to 18 million southern Californians in several cities, negotiated the purchase of 137 million cubic meters of water per year from farmers for the next 35 years. Without irrigation water, the highly productive land owned by these farmers is wasteland. The farmers who are selling their water rights would like to continue farming, but city officials are offering far more for the water than the farmers could possibly earn by using it to irrigate crops.^^63^^\n\nIn many countries, however, farmers are not compensated for a loss of irrigation water. In 2004, for example, Chinese farmers along the Juma River downstream from Beijing discovered that the river had stopped flowing. A diversion dam had been built near the capital to take river water for Yanshan Petrochemical, a state-owned industry. Although the farmers protested bitterly, it was a losing battle. For the 120,000 villagers downstream from the diversion dam, the loss of water could cripple their ability to make a living from farming.^^64^^\n\nWhether it is outright government expropriation, farmers being outbid by cities, or cities simply drilling deeper wells than farmers can afford, the world's farmers are losing the water war. They are faced with not only a shrinking water supply in many situations but also a shrinking share of that shrinking supply. Slowly but surely, cities are siphoning water from the world's farmers even as they try to feed some 70 million more people each year.^^65^^\n\n[[3.5 - Scarcity Crossing National Borders]]\n\n[[3.6 - A Food Bubble Economy]]\n\n[[3.7 - Additional Resources]]\n\n[[3.8 - Notes]]\n\n[[4 - Rising Temperatures and Rising Seas]]
Historically, water scarcity was a local issue. It was up to national governments to balance water supply and demand. Now this is changing as scarcity crosses national boundaries via the international grain trade. Since producing one ton of grain takes 1,000 tons of water (1,000 cubic meters), as noted earlier, importing grain is the most efficient way to import water. Countries are, in effect, using grain to balance their water books. Similarly, trading in grain futures is in a sense trading in water futures.^^66^^\n\nAfter China and India, there is a second tier of countries with large water deficits - Algeria, Egypt, Iran, Mexico, and Pakistan. Three of these - Algeria, Egypt, and Mexico - already import much of their grain. However, in a parallel move with China, water-short Pakistan abruptly turned to the world market in 2004 for imports of 1.5 million tons of wheat. Its need for imports is likely to climb in the years ahead.^^67^^\n\nThe Middle East and North Africa - from Morocco in the west through Iran in the east - has become the world's fastest-growing grain import market. The demand for grain is driven both by rapid population growth and by rising affluence, much of the latter derived from the export of oil. With virtually every country in the region pressing against its water limits, the growing urban demand for water can be satisfied only by taking irrigation water from agriculture.^^68^^\n\nEgypt, with some 74 million people, has become a major importer of wheat in recent years, vying with Japan - tradition-ally the leading wheat importer - for the top spot. It now imports 40 percent of its total grain supply, a number that edges steadily upward as its population outgrows the grain harvest produced with the Nile's water.^^69^^\n\nAlgeria, with 33 million people, imports more than half of its grain, which means that the water embodied in the imported grain exceeds the use of water for all purposes from domestic sources. Because of its heavy dependence on imports, Algeria is particularly vulnerable to disruptions, such as grain export embargoes.^^70^^\n\nOverall, the water required to produce the grain and other farm products imported into the Middle East and North Africa last year equaled the annual flow of the Nile River at Aswan. In effect, the region's water deficit can be thought of as another Nile flowing into the region in the form of imported grain.^^71^^\n\nIt is often said that future wars in the Middle East will more likely be fought over water than oil, but the competition for water is taking place in world grain markets. The countries that are financially the strongest, not necessarily those that are militarily the strongest, will fare best in this competition.\n\nKnowing where grain import needs will be concentrated tomorrow requires looking at where water deficits are developing today. Thus far, the countries importing much of their grain have been smaller ones. Now we are looking at fast-growing water deficits in both China and India, each with more than a billion people.^^72^^\n\nEach year the gap between world water consumption and the sustainable water supply widens. Each year the drop in the water table is greater than the year before. Both aquifer depletion and the diversion of water to cities will contribute to the growing irrigation water deficit and hence to a growing grain deficit in many water-short countries.\n\n[[3.6 - A Food Bubble Economy]]\n\n[[3.7 - Additional Resources]]\n\n[[3.8 - Notes]]\n\n[[4 - Rising Temperatures and Rising Seas]]
As noted earlier, overpumping is a way of satisfying growing food demand that virtually guarantees a future drop in food production when aquifers are depleted. Many countries are in essence creating a "food bubble economy" - one in which food production is artificially inflated by the unsustainable mining of groundwater.\n\nThe effects of overdrafting were not obvious when farmers began pumping on a large scale a few decades ago. The great attraction of pumping groundwater in contrast to large-scale surface water systems is that farmers can apply the water to crops precisely when it is needed, thereby maximizing water use efficiency. Groundwater is also available during the dry season, enabling many farmers in mild climatic regions to double crop.\n\nTo illustrate, yields of foodgrains in the Punjab on land irrigated from wells was 5.5 tons per hectare, while yields on land irrigated from canals averaged 3.2 tons per hectare. Similar data for the southern state of Andhra Pradesh also showed a strong advantage in pumped irrigation, with foodgrain yields averaging 5.7 tons per hectare compared with 3.4 tons on land irrigated with canal water.^^73^^\n\nIn the United States, 37 percent of all irrigation water comes from underground; the other 63 percent comes from surface sources. Yet three of the top grain-producing states - Texas, Kansas, and Nebraska - each get 70-90 percent of their irrigation water from the Ogallala aquifer, which is essentially a fossil aquifer with little recharge. The high productivity of groundwater-based irrigation means that the food production losses will be disproportionately large when the groundwater runs out.^^74^^\n\nAt what point does water scarcity translate into food scarcity? In which countries will the irrigation water losses from aquifer depletion translate into a drop in grain production? David Seckler and his colleagues at the International Water Management Institute, the world's premier water research group, summarized this issue well: "Many of the most populous countries of the world - China, India, Pakistan, Mexico, and nearly all the countries of the Middle East and North Africa - have literally been having a free ride over the past two or three decades by depleting their groundwater resources. The penalty for mismanagement of this valuable resource is now coming due and it is no exaggeration to say that the results could be catastrophic for these countries and, given their importance, for the world as a whole."^^75^^\n\nSince expanding irrigation helped triple the world grain harvest from 1950 to 2000, it comes as no surprise that water losses can shrink harvests. With water for irrigation, many countries are in a classic overshoot-and-decline mode. If countries that are overpumping do not move quickly to reduce water use and stabilize water tables, then an eventual drop in food production is almost inevitable.^^76~~^^\n\n[[3.7 - Additional Resources]]\n\n[[3.8 - Notes]]\n\n[[4 - Rising Temperatures and Rising Seas]]

In 2004, Sir David King, the U.K. government's Chief Scientific Advisor, reported some revealing new research confirming the relationship between carbon dioxide (CO~~2~~) levels and temperature over the last 740,000 years. Analysis of an Antarctic ice core drilled to a depth of three kilometers by British scientists showed that the atmospheric concentrations of CO~~2~~ consistently fluctuated between 200 parts per million (ppm) during the ice ages and 270 ppm during the warm intervals. This shift from ice age to warm period occurred many times and always within this CO~~2~~ range.^^1^^\n\nWhen the Industrial Revolution began, the atmospheric CO~~2~~ level was roughly 270 ppm. The 377 ppm registered for 2004 is not only far above any level over the last 740,000 years, it may be nearing a level not seen for 55 million years. At that time the earth was a tropical planet. There was no polar ice; sea level was 80 meters (260 feet) higher than it is today.\n\nThe destructive effects of higher temperatures are visible on many fronts. Crop-withering heat waves have lowered grain harvests in key food-producing regions in recent years. In 2002, record-high temperatures and associated drought reduced grain harvests in India, the United States, and Canada, dropping the world harvest 90 million tons, or 5 percent below consumption. The record-setting 2003 European heat wave contributed to a world harvest shortfall of 90 million tons. Intense heat and drought in the U.S. Corn Belt in 2005 contributed to a world shortfall of 34 million tons.^^3^^\n\nSuch intense heat waves also take a direct human toll. In 1995, 700 residents of Chicago died in a heat wave. In May 2002, in a heat wave in India that reached 50 degrees Celsius (122 degrees Fahrenheit), more than 1,000 people died in the state of Andhra Pradesh alone.^^4^^\n\nIn 2003, the searing heat wave that broke temperature records across Europe claimed 49,000 lives in eight countries. Italy alone lost more than 18,000 people, while 14,800 died in France. More than 15 times as many people died in Europe in this heat wave as died during the terrorist attacks on the World Trade Center and the Pentagon on September 11, 2001.^^5^^\n\nAmong the various manifestations of rising temperatures, ice melting and its effect on sea level are drawing scientists' attention. As sea level rises, low-lying island countries like Tuvalu and the Maldives and coastal cities like London, New York, and Shanghai will be among the first to feel the consequences.^^6^^\n\nThe insurance industry is painfully aware of the relationship between higher temperatures and storm intensity. As weather-related damage claims have soared, the last few years have brought a drop in earnings and a flurry of lowered credit ratings for both insurance companies and the reinsurance companies that insure them. Companies using historical records as a basis for calculating insurance rates for future storm damage are realizing that the past is no longer a reliable guide to the future.^^7^^\n\nThis is a problem not only for the insurance industry, but for all of us. We are altering the earth's climate, setting in motion trends we do not always understand with consequences we cannot anticipate.\n\n[[4.1 - Rising Temperature and Its Effects]]\n\n[[4.2 - The Crop Yield Effect]]\n\n[[4.3 - Reservoirs in the Sky]]\n\n[[4.4 - Melting Ice and Rising Seas]]\n\n[[4.5 - More Destructive Storms]]\n\n[[4.6 - Subsidizing Climate Change]]\n\n[[4.7 - Additional Resources]]\n\n[[4.8 - Notes]]\n\n[[5 - Natural Systems Under Stress]]\n\n----\nDownload pdf version of Chapter 4\n\n 20pp. (91 Kb)
Scientists at the National Aeronautics and Space Administration's Goddard Institute for Space Studies gather data from a global network of some 800 climate-monitoring stations to measure changes in the earth's average temperature. Their records go back 125 years, to 1880.^^8^^\n\nSince 1970, the earth's average temperature has risen by 0.8 degrees Celsius, or nearly 1.4 degrees Fahrenheit. During this span, the rise in temperature each decade was greater than in the preceding one. (See Figure 4-1.) Meteorologists note that the 22 warmest years on record have come since 1980. And the six warmest years since recordkeeping began in 1880 have come in the last eight years. Three of these six - 2002, 2003, and 2005 - were years in which major food-producing regions saw their crops wither in the face of record temperatures.^^9^^\n\nThe amount of CO~~2~~ in the atmosphere has risen substantially since the Industrial Revolution, with most of the rise coming since recordkeeping began in 1959. Since then it has risen every year, making this one of the world's most predictable environmental trends. As shown in Figure 4-2, CO~~2~~ levels turned sharply upward around 1960. Roughly a decade later, around 1970, the temperature too began to climb.^^10^^\n\nAgainst this backdrop of record increases, the projections of the Intergovernmental Panel on Climate Change (IPCC) that the earth's average temperature will rise 1.4-5.8 degrees Celsius (2.5-10.4 degrees Fahrenheit) during this century seem all too possible. Recent data on the temperature rise in some northern regions - such as Alaska, western Canada, and Siberia - coupled with the accelerated melting of the Greenland ice sheet, the melting of glaciers in mountain ranges throughout the world, and the likelihood at this writing that the global temperature for 2005 will set yet another record high all suggest that the global temperature rise will be close to the upper end of the IPCC projected range. Such an increase - of 5.8 degrees Celsius by 2100, a rise comparable to that between the last Ice Age and today - will create a world far different from the one we know.^^11^^\n\n<<tiddler Figure 4-1>>\n\n<<tiddler Figure 4-2>>\n\nAt a practical level, the IPCC projected rise in temperature is a global average. In reality, the rise will be very uneven. It will be much greater over land than over oceans, in the higher latitudes than over the equator, and in the continental interiors than in coastal regions.^^12^^\n\nHigher temperatures diminish crop yields, melt the snow/ice reservoirs in the mountains that feed the earth's rivers, cause more destructive storms, increase the area affected by drought, and cause more frequent and destructive wild fires.^^13^^\n\nIn a paper presented at the American Meteorological Society's annual meeting in San Diego, California, in January 2005, a team of scientists from the National Center for Atmospheric Research reported a dramatic increase in the earth's land surface affected by drought over the last few decades. They reported that the land experiencing very dry conditions expanded from less than 15 percent of the earth's total land area in the 1970s to roughly 30 percent by 2002. They attributed part of the change to a rise in temperature and part to reduced precipitation, with high temperatures becoming progressively more important during the latter part of the period. Lead author Aiguo Dai reported that most of the drying was concentrated in Europe and Asia, Canada, western and southern Africa, and eastern Australia.^^14^^\n\nResearchers with the U.S. Department of Agriculture's Forest Service reported that even a 1.6-degree-Celsius rise in summer temperature could double the area of wildfires in the 11 western states. The study, published in the August 2004 issue of //Conservation Biology//, drew on 85 years of fire and temperature records.^^15^^\n\nThe National Wildlife Federation (NWF) reports that if temperatures continue to rise, by 2040 one out of five of the Pacific Northwest's rivers will be too hot for salmon, steelhead, and trout to survive. Paula Del Giudice, Director of the Federation's Northwest Natural Resource Center, notes that "global warming will add an enormous amount of pressure onto what's left of the region's prime cold-water fish habitat."^^16^^\n\nEcosystems everywhere will be affected by higher temperatures, sometimes in ways we cannot easily predict. The Pew Center for Global Climate Change sponsored a mega-study analyzing some 40 scientific reports that link temperature with changes in ecosystems. Among the many changes reported are spring arriving nearly two weeks earlier in the United States, tree swallows nesting nine days earlier than they did 40 years ago, and a northward shift of red fox habitat that has it encroaching on the Arctic fox's range. Inuits were surprised by the appearance of robins, a bird they had never seen before. Indeed, there is no word in Inuit for "robin."^^17^^\n\nHector Galbraith of the University of Colorado-Boulder, a co-author of the Pew study, indicated that "the effects of this change are occurring much more rapidly than... expected." He also said "that ecosystems are much more sensitive to climate change than believed a decade ago." A study sponsored by Conservation International has predicted that continued climate change could drive more than a quarter of all land animals and plants to extinction.^^18^^\n\nDouglas Inkley, NWF Senior Science Advisor and senior author of a report to the Wildlife Society, notes, "We face the prospect that the world of wildlife that we now know - and many of the places we have invested decades of work in conserving as refugees and habitats for wildlife - will cease to exist as we know them, unless we change this forecast."^^19^^\n\n[[4.2 - The Crop Yield Effect]]\n\n[[4.3 - Reservoirs in the Sky]]\n\n[[4.4 - Melting Ice and Rising Seas]]\n\n[[4.5 - More Destructive Storms]]\n\n[[4.6 - Subsidizing Climate Change]]\n\n[[4.7 - Additional Resources]]\n\n[[4.8 - Notes]]\n\n[[5 - Natural Systems Under Stress]]
One of the economic trends most sensitive to higher temperatures is crop yields. Crops in many countries are grown at or near their thermal optimum, making them vulnerable to any rise in temperature. Even a relatively minor increase during the growing season of 1 or 2 degrees Celsius can shrink the grain harvest in major food-producing regions, such as the North China Plain, the Gangetic Plain of India, or the U.S. Corn Belt.^^20^^\n\nHigher temperatures can reduce or even halt photosynthesis, prevent pollination, and lead to crop dehydration. Although the elevated concentrations of atmospheric carbon dioxide that raise temperature can also raise crop yields, the detrimental effect of higher temperatures on yields overrides the CO~~2~~ fertilization effect for the major crops.\n\nIn a study of local ecosystem sustainability, Mohan Wali and his colleagues at Ohio State University noted that as temperature rises, photosynthetic activity in plants increases until the temperature reaches 20 degrees Celsius (68 degrees Fahrenheit). The rate of photosynthesis then plateaus until the temperature hits 35 degrees Celsius (95 degrees Fahrenheit), whereupon it begins to decline, until at 40 degrees Celsius (104 degrees Fahrenheit), photosynthesis ceases entirely.\n\nThe most vulnerable part of a plant's life cycle is the pollination period. Of the world's three food staples - rice, wheat, and corn - corn is particularly vulnerable. In order for corn to reproduce, pollen must fall from the tassel to the strands of silk that emerge from the end of each ear of corn. Each of these silk strands is attached to a kernel site on the cob. If the kernel is to develop, a grain of pollen must fall on the silk strand and then journey to the kernel site. When temperatures are uncommonly high, the silk strands quickly dry out and turn brown, unable to play their role in the fertilization process.\n\nThe effects of temperature on rice pollination have been studied in detail in the Philippines. Scientists there report that the pollination of rice falls from 100 percent at 93 degrees Fahrenheit (34 degrees Celsius) to near zero at 104 degrees Fahrenheit, leading to crop failure.^^22^^\n\nHigh temperatures can also dehydrate plants. While it may take a team of scientists to understand how temperature affects rice pollination, anyone can tell when a cornfield is suffering from heat stress. When a corn plant curls its leaves to reduce exposure to the sun, photosynthesis is reduced. And when the stomata on the underside of the leaves close to reduce moisture loss, CO~~2~~ intake is reduced, thereby restricting photosynthesis. At elevated temperatures, the corn plant, which under ideal conditions is so extraordinarily productive, goes into thermal shock.\n\nWithin the last few years, crop ecologists in several countries have been focusing on the precise relationship between temperature and crop yields. In an age of rising temperatures, their findings are disturbing. One of the most comprehensive of these studies was conducted at the International Rice Research Institute (IRRI) in the Philippines, the world's premier rice research organization. The team of eminent crop scientists there noted that from 1979 to 2003, the annual mean temperature at the research site rose by roughly 0.75 degrees Celsius.^^23^^\n\nUsing crop yield data from the experimental field plots for irrigated rice under optimal management practices for the years 1992-2003, the team's finding confirmed the rule of thumb emerging among crop ecologists - that a 1-degree-Celsius rise in temperature above the norm lowers wheat, rice, and corn yields by 10 percent. The IRRI finding was consistent with those of other recent research projects. The scientists concluded that "temperature increases due to global warming will make it increasingly difficult to feed Earth's growing population."^^24^^\n\nWhile this study analyzing rice yields was under way, an empirical historical analysis of the effect of temperature on corn and soybean yields was being conducted in the United States. It concluded that higher temperatures had an even greater effect on yields of these crops. Using data for 1982-98 from 618 counties for corn and 444 counties for soybeans, David Lobell and Gregory Asner concluded that for each 1 degree Celsius rise in temperature, yields declined by 17 percent.\n\nGiven the projected temperature increases in the U.S. Corn Belt, where a large share of the world's corn and soybeans is produced, these findings should be of concern to those responsible for world food security.\n\nTwo scientists in India, K.S. Kavi Kumar and Jyoti Parikh, assessed the effect of higher temperatures on wheat and rice yields. Basing their model on data from 10 sites, they concluded that in north India a 1-degree Celsius rise in mean temperature did not meaningfully reduce wheat yields, but a 2-degree rise lowered yields at almost all the sites. When they looked at temperature change alone, a 2-degree Celsius rise led to a decline in irrigated wheat yields ranging from 37 percent to 58 percent. When they combined the negative effects of higher temperature with the positive effects of CO~~2~~ fertilization, the decline in yields among the various sites ranged from 8 percent to 38 percent. For a country projected to add 500 million people by mid-century, this is a troubling prospect.^^26^^\n\n[[4.3 - Reservoirs in the Sky]]\n\n[[4.4 - Melting Ice and Rising Seas]]\n\n[[4.5 - More Destructive Storms]]\n\n[[4.6 - Subsidizing Climate Change]]\n\n[[4.7 - Additional Resources]]\n\n[[4.8 - Notes]]\n\n[[5 - Natural Systems Under Stress]]
Snow/ice masses in mountains are nature's freshwater reservoirs - nature's way of storing water to feed rivers during the summer dry season. Now they are being threatened by the rise in temperature. Even a 1-degree rise in temperature in mountainous regions can markedly reduce the share of precipitation falling as snow and can boost that coming down as rain. This in turn increases flooding during the rainy season and reduces the snowmelt to feed rivers during the dry season.\n\nIn some agricultural regions, these "reservoirs in the sky" are the leading source of irrigation and drinking water. In the southwestern United States, for instance, the Colorado River - the primary source of irrigation water - depends on snowfields in the Rockies for much of its flow. California, in addition to depending heavily on the Colorado, also relies on snowmelt from the Sierra Nevada in the eastern part of the state. Both the Sierra Nevada and the coastal range supply irrigation water to California's Central Valley, the world's fruit and vegetable basket.\n\nPreliminary results of an analysis of rising temperature effects on three major river systems in the western United States - the Columbia, the Sacramento, and the Colorado - indicate that the winter snow pack in the mountains feeding them will be dramatically reduced and that winter rainfall and flooding will increase accordingly.\n\nWith a business-as-usual energy policy, global climate models project a 70-percent reduction in the amount of snow pack for the western United States by mid-century. A detailed study of the Yakima River Valley, a vast fruit-growing region in Washington state, by the U.S. Department of Energy's Pacific Northwest National Laboratory shows progressively heavier harvest losses as the snow pack shrinks, reducing irrigation water flows. A 2-degree-Celsius rise in temperature would reduce farm income in the valley by $92 million; a rise of 4 degrees Celsius would cut farm income by $163 million, nearly a quarter of the current harvest.^^28^^\n\nIn Central Asia, the agriculture in several countries - Uzbekistan, Turkmenistan, Kyrgyzstan, Kazakhstan, Tajikistan, and Afghanistan - depends heavily on snowmelt from the Hindu Kush, Pamir, and Tien Shan mountain ranges for irrigation water. Nearby Iran gets much of its water from the snowmelt in the 5,700-meter Alborz Mountains between Tehran and the Caspian Sea.^^29^^\n\nLargest of all, where farmers are concerned, is the vast snow/ice mass in the Himalayas. Every major river in Asia, where half the world's people live, originates in the Himalayas, including the Indus, the Ganges, the Mekong, the Yangtze, and the Yellow. If warmer temperatures increase rainfall and reduce snowfall in the Himalayas, there will be more flooding during the rainy season and less snowmelt to feed rivers during the dry season.^^30^^\n\nReduced snow pack to feed the Yellow River flow will shrink China's wheat harvest, the largest in the world. Alterations in the flow of the Yangtze River will directly affect China's rice harvest - also the world's largest. And India's wheat harvest, second only to China's, will be affected by the flows of both the Indus and the Ganges. Anything that lowers the summer flow of the Mekong will affect the rice harvest of Viet Nam, a leading exporter.^^31^^\n\nThe shrinking of glaciers in the Himalayas could affect the water supply for hundreds of millions of people. In countries like India and China, the water stored during the rainy season as snow and ice for release in the dry season would be reduced or, in some cases, disappear entirely. The result would be more destructive floods alternating annually with more severe early summer water shortages.^^32^^\n\nThere are many more mountain ranges where snow/ice regimes are shifting, including the Alps and the Andes. The snow/ice masses in the world's leading mountain ranges and the water they store as ice and snow is taken for granted simply because it has been there since before agriculture began. Now that is changing. If we continue raising the earth's temperature, we risk losing these reservoirs in the sky on which cities and farmers depend.^^33^^\n\n[[4.4 - Melting Ice and Rising Seas]]\n\n[[4.5 - More Destructive Storms]]\n\n[[4.6 - Subsidizing Climate Change]]\n\n[[4.7 - Additional Resources]]\n\n[[4.8 - Notes]]\n\n[[5 - Natural Systems Under Stress]]
In its landmark third report, released in early 2001, the IPCC projected that sea level would rise during this century by 0.09-0.88 meters (4-35 inches) as a result of thermal expansion and ice melting. Numerous new studies during the four years since then indicate that the earth's ice cover is melting even faster than IPCC scientists projected.^^34^^\n\nA 2002 study by two scientists from the University of Colorado's Institute of Arctic and Alpine Research showed that the melting of large glaciers on the west coast of Alaska and in northern Canada is accelerating. Earlier data had indicated that this melting was raising sea level by 0.14 millimeters per year, but new data for the 1990s show that the more rapid melting is now raising sea level by 0.32 millimeters a year - more than twice as fast.^^35^^\n\nThis study is reinforced by a U.S. Geological Survey (USGS) study that indicated glaciers are now shrinking in all 11 of Alaska's glaciated mountain ranges. An earlier USGS study reported that the number of glaciers in Glacier National Park in the United States had dwindled from 150 in 1850 to fewer than 50 today. The remaining glaciers are projected to disappear within 30 years, leaving future generations of visitors to puzzle over the park's name.^^36^^\n\nAnother team of USGS scientists, which used satellite data to measure changes in the area covered by glaciers worldwide, described an accelerated melting of glaciers in several mountainous regions, including the South American Andes, the Swiss Alps, and the French and Spanish Pyrenees.^^37^^\n\nThe melting of glaciers is gaining momentum throughout the Andes. Glaciologist Lonnie Thompson of Ohio State University reports that the Qori Kalis glacier, on the west side of the Quelccaya ice cap in the Peruvian Andes, shrank three times as fast each year from 1998 to 2000 as it did between 1995 and 1998. And the earlier rate, in turn, was nearly double the annual rate of retreat from 1993 to 1995. Thompson projects that the Quelccaya ice cap will disappear entirely between 2010 and 2020. In nearby Ecuador, the Antisana glacier, which supplies half of the water for Quito, has retreated nearly 100 meters in the last eight years.^^38^^\n\nBernard Francou, research director for the French government's Institute of Research and Development, believes that 80 percent of South American glaciers will disappear within the next 15 years. For countries like Bolivia, Peru, and Ecuador, which rely on glaciers for water for household and irrigation use, this is not good news.^^39^^\n\nThe European Alps are also suffering a meltdown. Scientists at Zurich University report that glaciers in Switzerland shrank by 1 percent from 1973 to 1985 but that the area covered shrank 18 percent between 1985 and 2000. They observed that "the changes could also impact tourism, a crucial pillar of the Swiss economy, as the country's scenic glacial valleys become barren and rocky." As the glaciers disappear and the snowline retreats upward, the winter ski season will shrink.^^40^^\n\nLonnie Thompson's studies of Kilimanjaro show that between 1989 and 2000, Africa's tallest mountain lost 33 percent of its ice field. He projected that its snowcap could disappear entirely by 2015. In March 2005, the //Guardian// in London reported: "Africa's tallest mountain, with its white peak, is one of the most instantly recognizable sites in the world. But as this aerial photograph shows, Kilimanjaro's trademark snowy cap, at 5,895 meters (19,340 feet), is now all but gone - 15 years before scientists predicted it."^^41^^\n\nThe vast snow/ice mass in the Himalayas is also retreating. The Union Internationale des Associations d'Alpinisme reports that the glacier that ended at the base camp from which Edmund Hillary and Tenzing Norgay launched their history-making ascent of Everest in 1953 has retreated about 5 kilometers (3 miles). Geologist Jeffrey Kargel, who studies the Himalayas, is not surprised by this. "That fits in with the general picture of what's happening in Nepal, India, Bhutan and, to a smaller extent, Tibet," he says.^^42^^\n\nA recently completed study by a team of more than 50 U.S. and Chinese scientists over 26 years measured the accelerated melting of the glaciers in Western China. The study reported that the volume of China's 46,298 glaciers has shrunk by 5.5 percent in the past 24 years. The melting of glaciers in this region, as in most other areas of the world, has accelerated sharply since the early 1990s.^^43^^\n\nYao Tandong, a leading Chinese glaciologist and contributor to the study, predicted that two thirds of China's glaciers could be gone by 2060. Melting of the vast Himalayan ice fields, which contain more ice than any region outside of the poles, could dramatically raise sea level. Yao Tandong summarized the situation: "The full-scale glacier shrinkage in the plateau region will eventually lead to an ecological catastrophe."^^44^^\n\nAnother recent study, //Impacts of a Warming Arctic//, concluded that the Arctic is warming almost twice as fast as the rest of the planet. Conducted by the Arctic Climate Impact Assessment (ACIA) team, an international group of 300 scientists, the study found that in the regions surrounding the Arctic, including Alaska, western Canada, and Eastern Russia, winter temperatures have already climbed by 3-4 degrees Celsius (4-7 degrees Fahrenheit) over the last half-century. Robert Corell, chair of ACIA observes, "The impacts of global warming are affecting people now in the Arctic." This region, he says, "is experiencing some of the most rapid and severe climate change on Earth."^^45^^\n\nIn testimony before the U.S. Senate Commerce Committee, Sheila Watt-Cloutier, an Inuit speaking on behalf of the 155,000 Inuits who live in Alaska, Canada, Greenland, and the Russian Federation, described the Inuits' struggle to survive in the fast-changing Arctic climate as "a snapshot of what is happening to the planet." She called the warming of the Arctic "a defining event in the history of this planet." And she went on to say "the Earth is literally melting."^^46^^\n\nThe ACIA report described how the retreat of the sea ice has "devastating consequences for polar bears" whose very survival may be at stake. Also threatened are the ice-living seals, a basic food source for the Inuits.^^47^^\n\nHigher Arctic temperatures are also thawing what had been perpetually frozen soils of the region. As the tundra thaws, it destabilizes and damages buildings, pipelines, and roads. The melting of the tundra has effects far beyond local structural problems. A report in //Science// says, "No one knows exactly how much carbon is locked up in boreal and alpine permafrost, but estimates range from 350 to 450 gigatons [billion tons] - perhaps a quarter to a third of all soil carbon. The big question is what will happen if even a fraction of this massive carbon store is liberated." This compares with the 7 billion tons of carbon that is emitted from burning fossil fuels each year.^^48^^\n\nThe scientists chronicling the warming of the Arctic are perhaps most concerned about the effect on Greenland. If all the ice in the Arctic Sea melts, it will not affect sea level because that ice is already in the water. But if the warming of the Arctic melts the Greenland ice sheet, which is a mile and a half thick in some places, sea level would rise by 7 meters (23 feet). Such a melting of the Greenland ice sheet would be measured in centuries, not years. Nonetheless, recent maps show rapid melting around the ice sheet's outer edges, particularly on the eastern coast.^^49^^\n\nScientists are concerned about the melting of the Greenland ice sheet not only because of its obvious effect on sea level, but also because it might disrupt ocean circulation, particularly the flow of the Gulf Stream. Under current conditions, the Gulf Stream that brings warm surface water northward from the South Atlantic supports Western Europe's mild climate. As the high-salinity warm water moves northward, it cools as a result of heat loss and evaporation, becoming more dense and salty. This eventually causes it to sink and then flow southward as deep water. An influx of fresh water from melting of the Greenland ice sheet or of Arctic sea ice could disrupt this circulation pattern, resulting in somewhat lower temperatures in the northeastern United States and eastern Canada and a sharp temperature drop in Europe. Historical evidence suggests that such shifts have sometimes come quickly - in a matter of years or decades.^^50^^\n\nAs the Arctic sea ice melts, it opens the possibility of using the Arctic Sea as a shipping route between the Atlantic and Pacific Oceans. The search for the Northwest Passage, a dream of early explorers who otherwise had to sail around the Cape of Good Hope, could become a nightmare for our early twenty-first century society. Shipping companies are already looking at potential shortcuts. The trip from Europe to Asia via the Panama Canal typically covers some 12,600 nautical miles, according to an article in Canada's //Globe and Mail//, while the trip via the Northwest Passage would be shortened to 7,900 nautical miles. The risk is that the environmental damage from any accidents, such as an oil spill in the Arctic Sea, could last for decades if not longer in this frigid environment.^^51^^\n\nAt the other end of the earth, the 2-kilometer thick Antarctic ice sheet covers a continent about twice the size of Australia and contains 70 percent of the world's fresh water. Ice shelves that extend from the continent into the surrounding seas are beginning to break up at an alarming pace.^^52^^\n\nThe ice shelves surrounding Antarctica are formed by the flow of glaciers off the continent to lower levels in the surrounding sea. This flow of ice, fed by the continuous formation of new ice on land and culminating in the breakup of the shelves on the outer fringe and the calving of icebergs, is not new. What is new is the pace of this process. When Larsen A, a huge ice shelf on the east coast of the Antarctic Peninsula, broke up in 1995, it was a signal that all was not well in the region. Then in 2000, a huge iceberg nearly the size of Connecticut - 11,000 square kilometers, or 4,250 square miles - broke off the Ross Ice Shelf.^^53^^\n\nAfter Larsen A broke up, it was only a matter of time, given the rise in temperature in the region, before Larsen B would do the same. In November 2001, an alert went out to the scientific community from a researcher at the Instituto Ant√°rtico Argentino, who noted the unusually warm spring temperature and the 20-percent acceleration in the flow of the ice shelf. So when the northern part of the Larsen B ice shelf collapsed into the sea in March 2002, it was not a total surprise. At about the same time, a huge chunk of ice broke off the Thwaite Glacier. Covering 5,500 square kilometers, this iceberg was the size of Rhode Island.^^54^^\n\nEven veteran ice watchers are amazed at how quickly the disintegration is occurring. "The speed of it is staggering," said Dr. David Vaughan, a glaciologist at the British Antarctic Survey, which has been monitoring the Larsen Ice Shelf closely. Along the Antarctic Peninsula, in the vicinity of the Larsen Ice Shelf, the average temperature has risen 2.5 degrees Celsius over the last five decades. Higher temperatures lead to ice melting on the surface of the ice shelves. Scientists theorize that as the melted water on the surface penetrates fractures, it weakens the ice, making it vulnerable to further fracturing.^^55^^\n\nWhen ice shelves already in the water break off from the continental ice mass, this does not have much direct effect on sea level per se. But without the ice shelves to impede the flow of glacial ice, typically moving 400-900 meters a year, the flow of ice from the continent could accelerate, leading to a thinning of the ice sheet on the edges of the Antarctic continent. If this were to happen, sea level would rise. Dr. Neal Young of the Antarctic Cooperative Research Centre at the University of Tasmania in Australia notes that after Larsen A broke off, the upstream rate of glacial flow at least doubled.^^56^^\n\nThe accelerated melting of ice, which is consistent with the accelerating rise in temperature that has occurred since 1980, is of great concern in low-lying regions of coastal countries and low-lying island countries. Perhaps the most easily measured effect of rising sea level is the inundation of coastal areas. Donald F. Boesch, with the University of Maryland's Center for Environmental Sciences, estimates that for each 1-meter rise in sea level, the shoreline will retreat by an average 1,500 meters, or nearly a mile.^^57^^\n\nIn 2000, the World Bank published a map showing that a 1-meter rise in sea level would inundate half of Bangladesh's rice-land. With a rise in sea level of up to 1 meter forecast for this century, tens of millions of Bangladeshis would be forced to migrate. In a country with 142 million people - already one of the most densely populated on earth - this would be a traumatic experience. Rice-growing river floodplains in other Asian countries would also be affected, including India, Thailand, Viet Nam, Indonesia, and China. With a 1-meter rise in sea level, more than a third of Shanghai, a city of 13 million people, would be under water.^^58^^\n\nSuch a rise would cost the United States 36,000 square kilometers (14,000 square miles) of land, most of it in the middle Atlantic and Mississippi Gulf states. With a 50-year storm surge, large portions of Lower Manhattan and the National Mall in the center of Washington, D.C., would be flooded with seawater.^^59^^\n\nWhile public attention focuses on the effect of ice melting on sea level rise, the thermal expansion of the oceans as a result of rising temperature is also raising sea level. At present, scientists estimate the relative contributions of ice melting and thermal expansion to sea level rise to be about the same. Together, the two are raising sea level at a measurable rate. It has become an indicator to watch - a trend that could force a human migration of unimaginable dimensions. It also raises questions about responsibility to future generations that humanity has never before faced.^^60^^\n\n[[4.5 - More Destructive Storms]]\n\n[[4.6 - Subsidizing Climate Change]]\n\n[[4.7 - Additional Resources]]\n\n[[4.8 - Notes]]\n\n[[5 - Natural Systems Under Stress]]
Rising seas are not the only threat that comes with elevated global temperatures. Higher surface water temperatures in the tropical oceans mean more energy radiating into the atmosphere to drive tropical storm systems, leading to more frequent and more destructive storms. The combination of rising seas, more powerful storms, and stronger storm surges can be devastating.^^61^^\n\nIn the fall of 1998, Hurricane Mitch - one of the most powerful storms ever to come out of the Atlantic, with winds approaching 200 miles per hour - hit the east coast of Central America. As atmospheric conditions stalled the normal northward progression of the storm, some 2 meters of rain were dumped on parts of Honduras and Nicaragua within a few days. The deluge collapsed homes, factories, and schools, leaving them in ruins. It destroyed roads and bridges. Seventy percent of the crops and much of the topsoil in Honduras were washed away - topsoil that had accumulated over long stretches of geological time. Huge mudslides destroyed villages, sometimes burying local populations.^^62^^\n\nThe storm left 11,000 dead. Thousands more were never found. The basic infrastructure - the roads and bridges in Honduras and Nicaragua - was largely destroyed. President Flores of Honduras summed it up this way: "Overall, what was destroyed over several days took us 50 years to build." The damage from this storm, exceeding the annual gross national product of the two countries, set their economic development back by 20 years.^^63^^\n\nIn 2004, Japan experienced a record 10 typhoons (hurricanes) that collectively caused $10 billion worth of losses. During the same season, the state of Florida was hit by 4 of the 10 most costly hurricanes in U.S. history. These 4 hurricanes together generated insurance claims of $22 billion.^^64^^\n\nA year later, these storms were dwarfed when Hurricane Katrina came onshore in the U.S. Gulf region with a storm surge of more than 20 feet that totally destroyed many coastal towns. The storm also flooded New Orleans, leaving much of it uninhabitable. Altogether the storm generated hundreds of thousands of refugees from Alabama, Mississippi, and Louisiana. This powerful storm, fueled by higher temperatures of surface waters in the Gulf, left in its wake a bill estimated early on at $200 billion. Since it will take years for the region to fully recover, the cost could climb even higher.^^65^^\n\nAgainst this backdrop, insurance companies and reinsurance companies find it difficult to calculate a safe level of premiums, since the historical record traditionally used to calculate insurance fees is no longer a guide to the future. For example, the number of major flood disasters worldwide has grown during each of the last several decades, increasing from 6 major floods in the 1950s and 1960s to 8 in the 1970s, 18 in the 1980s, and 26 in the 1990s.^^66^^\n\nThe insurers are convinced that with higher temperatures and more energy driving storm systems, future losses will be even greater. They are concerned about whether the industry can remain solvent under this onslaught of growing damages. So, too, is Moody's Investors Service, which in 2002 downgraded the creditworthiness of several of the world's leading reinsurance companies. Since then, one of these firms - Munich Re - reported that 2004 was a record year of claims for the insurance industry worldwide even after adjusting for inflation.^^67^^\n\nThomas Loster, a Munich Re climate expert, said at the end of 2004: "As in 2002 and 2003, the overall balance of natural catastrophes is again clearly dominated by weather-related disasters, many of them exceptional and extreme. ... We need to stop this dangerous experiment humankind is conducting on the Earth's atmosphere." The insurance industry is particularly concerned about new climate-related risks that may be emerging, such as Hurricane Catarina, which developed in 2004 in the South Atlantic, where water temperatures are not usually high enough to generate a hurricane. Whether Catarina, which came onshore in southern Brazil, is an anomalous event or the beginning of a disturbing new trend remains to be seen.^^68^^\n\nMunich Re has published a list of storms with insured losses of $1 billion or more. The first such natural disaster came in 1983, when Hurricane Alicia struck the United States, racking up $1.5 billion in insured losses. Of the 49 natural catastrophes with $1 billion or more of insured losses recorded through the end of 2004, 3 were earthquakes, including the devastating 2004 Asian tsunami; the other 46 were weather-related - storms, floods, hurricanes, or wildfires. During the 1980s, there were 3 such events; during the 1990s, there were 26; and during the first half of the current decade, 2000 through 2004, there were 17.^^69^^\n\nPrior to Hurricane Katrina, the two largest events in terms of total damage were Hurricane Andrew in 1992, which took down 60,000 homes and racked up $30 billion worth of damage, and the flooding of China's Yangtze river basin in 1998, which also cost an estimated $30 billion, a sum comparable to the value of China's rice harvest. Part of the growing damage toll is due to greater urban and industrial development in coastal areas and river floodplains. But part is due to more frequent, more destructive storms.^^70^^\n\nThe regions most vulnerable to more powerful storms currently are the Atlantic and Gulf Coasts of the United States and the Caribbean countries. In Asia, it is East and Southeast Asia, including the Philippines, Taiwan, Japan, China, and Viet Nam, that are likely to bear the brunt of the powerful storms crossing the Pacific. Further west, in the Bay of Bengal, Bangladesh and the east coast of India are particularly vulnerable.\n\nWestern Europe, traditionally experiencing a heavily damaging winter storm perhaps once in a century, had its first winter storm to exceed $1 billion in 1987 - one that wreaked $3.7 billion in destruction, $3.1 billion of which was covered by insurance. Since then, it has had eight winter storms with insured losses ranging from $1.3 billion to $5.9 billion.^^71^^\n\nAndrew Dlugolecki, a senior officer at the CGMU Insurance Group, the largest insurance company in the United Kingdom, notes that damage from atmospherically related events has increased by roughly 10 percent a year. "If such an increase were to continue indefinitely," he notes, "by 2065 storm damage would exceed the gross world product. The world obviously would face bankruptcy long before then." In the real world, few growth trends continue at a fixed rate for several decades, but Dlugolecki's basic point is that climate change can be destructive, disruptive, and very costly.^^72^^\n\n[[4.6 - Subsidizing Climate Change]]\n\n[[4.7 - Additional Resources]]\n\n[[4.8 - Notes]]\n\n[[5 - Natural Systems Under Stress]]
At a time of mounting public concern about climate change driven by the burning of fossil fuels, the world fossil fuel industry is still being subsidized by taxpayers at more than $210 billion per year. Fossil fuel subsidies belong to another age, a time when development of the oil and coal industries was seen as a key to economic progress - not as a threat to our twenty-first century civilization. Once in place, subsidies lead to special interest lobbies that fight tooth and nail against eliminating them, even those that were not appropriate in the first place.^^73^^\n\nIn the United States, oil and gas companies are now perhaps the most powerful lobbyists in Washington. Between 1990 and 2004, they amassed $181 million in campaign contributions in an effort to protect special tax deductions worth billions. In testimony before the House Ways and Means Committee in 1999, Donald Lubick, U.S. Treasury Assistant Secretary for Tax Policy, said in reference to oil and gas companies: "This is an industry that probably has a larger tax incentive relative to its size than any other industry in the country." That such profitable investments are possible is a measure of the corruption of the\n\nU.S. political system, particularly the capacity of those with money to shape the economy to their advantage.^^74^^\n\nSubsidies permeate and distort every corner of the global economy. Germany's coal mining subsidy was initially justified in part as a job protection measure, for example. At its peak, the government was subsidizing the industry to the tune of nearly $90,000 per year for each worker. In purely economic terms, it would have made more sense to close the mines and pay miners not to work.^^75^^\n\nMany subsidies are largely hidden from taxpayers. This is especially true of the fossil fuel industry, whose subsidies include such things as a depletion allowance for oil pumping in the United States. Even more dramatic are the routine U.S. military expenditures to protect access to Middle Eastern oil, which were calculated by analysts at the Rand Corporation before the most recent Iraq war to fall between $30 billion and $60 billion a year, while the oil imported from the region was worth only $20 billion.^^76^^\n\nA 2001 study by Redefining Progress shows U.S. taxpayers subsidizing automobile use at $257 billion a year, or roughly $2,000 per taxpayer. In addition to subsidizing carbon emissions, this also means that taxpayers who do not own automobiles, including those too poor to afford them, are subsidizing those who do.^^77^^\n\nOne of the bright spots about this subsidization of fossil fuels is that it provides a reservoir of tax deductions that can be diverted to climate-benign, renewable sources of energy, such as wind, solar, and geothermal energy. Shifting these subsidies from fossil fuels to the development of renewable sources would be a win-win situation, as described in Chapter 12. To subsidize the use of fossil fuels is to subsidize crop-withering heat waves, melting ice, rising seas, and more destructive storms. Perhaps it is time for the world's taxpayers to ask if this is how they want their hard-earned money to be spent.\n\n[[4.7 - Additional Resources]]\n\n[[4.8 - Notes]]\n\n[[5 - Natural Systems Under Stress]]

In 1938, Walter Lowdermilk, a senior official in the Soil Conservation Service of the U.S. Department of Agriculture (USDA), traveled abroad to look at lands that had been cultivated for thousands of years, seeking to learn how these older civilizations had coped with soil erosion. He found that some had managed their land well, maintaining its fertility over long stretches of history, and were thriving. Others had failed to do so and left only remnants of their illustrious pasts.^^1^^\n\nIn a section of his report entitled "The Hundred Dead Cities," he described a site in northern Syria, near Aleppo, where ancient buildings were still standing in stark isolated relief, but they were on bare rock. During the seventh century, the thriving region had been invaded, initially by a Persian army and later by nomads out of the Arabian Desert. In the process, soil and water conservation practices used for centuries were abandoned. Lowdermilk noted, "Here erosion had done its worst. ... if the soils had remained, even though the cities were destroyed and the populations dispersed, the area might be repeopled again and the cities rebuilt, but now that the soils are gone, all is gone."^^2^^\n\nNow fast forward to a trip in 2002 by a U.N. team to assess the food situation in Lesotho, a small country of 2 million people imbedded within South Africa. Their finding was straightforward: "Agriculture in Lesotho faces a catastrophic future; crop production is declining and could cease altogether over large tracts of the country if steps are not taken to reverse soil erosion, degradation, and the decline in soil fertility." Michael Grunwald, reports in the //Washington Post// that nearly half of the children under five in Lesotho are stunted physically. "Many," he says, "are too weak to walk to school."^^3^^\n\nWhether the land is in northern Syria, Lesotho, or elsewhere, the health of the people living on it cannot be separated from the health of the land itself. A large share of the world's 852 million hungry people live on land with soils worn thin by erosion.^^4^^\n\nMerciless human demands are putting stresses on forests, rangelands, and fisheries that they cannot withstand. We are also destroying many of the plant and animal species with which we share the planet. Worldwide, species are now disappearing at 1,000 times the rate at which new species evolve: we have put the extinction clock on fast-forward.^^5^^\n\n[[5.1 - Shrinking Forests: The Costs]]\n\n[[5.2 - Losing Soil]]\n\n[[5.3 - Deteriorating Rangelands]]\n\n[[5.4 - Advancing Deserts]]\n\n[[5.5 - Collapsing Fisheries]]\n\n[[5.6 - Disappearing Plants and Animals]]\n\n[[5.7 - Additional Resources]]\n\n[[5.8 - Notes]]\n\n[[6 - Early Signs of Decline]]\n\n----\nDownload pdf version of Chapter 5\n\n 20pp. (85 Kb)
In early December 2004, Philippine President Gloria Macapagal Arroyo "ordered the military and police to crack down on illegal logging, after flash floods and landslides, triggered by rampant deforestation, killed nearly 340 people," according to news reports. Fifteen years earlier, in 1989, the government of Thailand announced a nationwide ban on tree cutting following severe flooding and the heavy loss of life in landslides. And in August 1998, following several weeks of record flooding in the Yangtze river basin and a staggering $30 billion worth of damage, the Chinese government banned all tree cutting in the basin, home to 400 million people. Each of these governments had belatedly learned a costly lesson, namely that services provided by forests, such as flood control, may be far more valuable to society than the lumber in those forests.^^6^^\n\nAt the beginning of the twentieth century, the earth's forested area was estimated at 5 billion hectares. Since then it has shrunk to 3.9 billion hectares - with the remaining forests rather evenly divided between tropical and subtropical forests in developing countries and temperate/boreal forests in industrial countries.^^7^^\n\nWorld forest loss is concentrated in developing countries. Since 1990, the loss in these nations has averaged 13 million hectares a year, an area roughly the size of Kansas. Overall, the developing world is losing 6 percent of its forests per decade. The industrial world is actually gaining an estimated 3.6 million hectares of forestland each year, principally from abandoned cropland that is returning to forests on its own, as in Russia, and from the spread of commercial forestry plantations.^^8^^\n\nUnfortunately, even these official data from the U.N.'s Food and Agriculture Organization (FAO) do not reflect the gravity of the situation. For example, tropical forests that are clearcut or burned off rarely recover. They simply become wasteland or at best scrub forest, yet they are still included in official forestry numbers. Plantations, too, count as forest area, yet they also are a far cry from the old-growth forest they sometimes replace.\n\nThe World Resources Institute (WRI) reports that of the forests that do remain standing, "the vast majority are no more than small or highly disturbed pieces of the fully functioning ecosystems they once were." Only 40 percent of the world's remaining forest cover can be classified as frontier forest, which WRI defines as "large, intact, natural forest systems relatively undisturbed and big enough to maintain all of their biodiversity, including viable populations of the wide-ranging species associated with each type."^^9^^\n\nPressures on forests continue to mount. Use of firewood, paper, and lumber is expanding. Of the 3.34 billion cubic meters of wood harvested worldwide in 2003, over half was used for fuel. In developing countries, fuelwood accounts for nearly three fourths of the total.^^10^^\n\nDeforestation to supply fuelwood is extensive in the Sahelian zone of Africa and the Indian subcontinent. As urban firewood demand surpasses the sustainable yield of nearby forests, the woods slowly retreat from the city in an ever larger circle, a process clearly visible from satellite photographs taken over time. As the circles enlarge, the transport costs of firewood increase, triggering the development of a charcoal industry, a more concentrated form of energy with lower transport costs. March Turnbull writes in //Africa Geographic Online//: "Every large Sahelian town is surrounded by a sterile moonscape. Dakar and Khartoum now reach out further than 500 kilometers for charcoal, sometimes into neighboring countries."^^11^^\n\nLogging for lumber also takes a heavy toll, as is most evident in Southeast Asia and Africa. In almost all cases, logging is done by foreign corporations more interested in maximizing a onetime harvest than in managing for a sustainable yield in perpetuity. Once a country's forests are gone, companies move on, leaving only devastation behind. Nigeria and the Philippines have both lost their once-thriving tropical hardwood export industries and are now net importers of forest products.^^12^^\n\nForest losses from clearing land for farming and ranching, usually by burning, are concentrated in the Brazilian Amazon, the Congo basin, and Borneo. After having lost 97 percent of its Atlantic rainforest, Brazil is now destroying the Amazon rainforest. This huge forest, roughly the size of Europe, was largely intact until 1970. Since then, 20 percent of it has been lost.^^13^^\n\nThe fast-rising demand for palm oil led to an 8-percent annual growth rate in the palm plantation area in Malaysian Borneo (Sarawak and Sabah) between 1998 and 2003. In Kalimantan, the Indonesian part of Borneo, growth in palm oil plantings is higher, at over 11 percent. Now that palm oil is emerging as a leading biodiesel fuel, growth in its cultivation will likely climb even faster. The near-limitless demand for biodiesel now threatens the remaining tropical forests in Borneo and elsewhere.^^14^^\n\nHaiti, a country of 8 million people, was once largely covered with forests. Now there are forests standing on scarcely 2 percent of its land largely because trees are cut for firewood. In September 2004, tropical storm Jeanne left 1,500 dead and over 1,000 more missing and presumed dead. With the trees gone, the soil had washed away and there was little left to hold the downpour. Once a tropical paradise, Haiti is now a case study of a country committing ecological and economic suicide. As its forests have shrunk and its soils have eroded, Haiti has been caught in an eco-logical/economic downward spiral from which it has not been able to escape. It is a country sustained by international life-sup-port systems of food aid and economic assistance.^^15^^\n\nHaiti is a classic case of overshoot and collapse. First the trees go, then the soil, and finally the society itself. Without food from abroad, Haiti's population might now be declining as a result of hunger. Haiti is a microcosm of what much of the earth will be like if deforestation continues.\n\nScores of countries are suffering from disastrous flooding as a result of deforestation. In 2000, Mozambique was partially inundated as the Limpopo overflowed its banks, taking thousands of lives and destroying homes and crops on an unprecedented scale. The Limpopo river basin, which has lost 99 percent of its original tree cover, will likely face many more such floods.^^16^^\n\nThe biologically rich rainforest of Madagascar is also disappearing fast. As the trees are cut either to produce charcoal or to clear land in order to grow food for the island's increasing population, the sequence of events is all too familiar. Environmentalists warn that Madagascar could soon become a landscape of scrub growth and sand.^^17^^\n\nWhile deforestation accelerates the flow of water back to the ocean, it also can reduce the recycling of rainfall inland. Some 20 years ago, two Brazilian scientists, Eneas Salati and Peter Vose, pointed out in //Science// that when rainfall coming from clouds moving in from the Atlantic fell on healthy Amazon rainforest, one fourth of the water ran off and three fourths evaporated into the atmosphere to be carried further inland to provide more rainfall. When land is cleared for grazing or farming, however, the amount that runs off and returns to the sea increases dramatically while that which is recycled inland falls alarmingly.\n\nEcologist Philip Fearnside, who has spent his career studying the Amazon, observes that the agriculturally prominent south-central part of Brazil depends on water that is recycled inland via the Amazon rainforest. If the Amazon is converted into a cattle pasture, he notes, there will be less rainfall to support agriculture.^^19^^\n\nA similar situation may be developing in Africa, where deforestation and land clearing are proceeding rapidly as firewood use mounts and as logging firms clear large tracts of virgin forests. In Malawi, a country of 13 million in East Africa, forest cover has shrunk from 47 percent of the country's land area to some 28 percent in a matter of years. The cutting of trees to produce charcoal and to cure tobacco is leading to a sequence of events paralleling that in Haiti.^^20^^\n\nAs the trees disappear, rainfall runoff increases and the land is deprived of the water from evapotranspiration. Consulting hydrogeologist Jim Anscombe notes: "Driven by energy from the sun, the trees pump water from the water table, through the roots, trunk and leaves, up into the process of transpiration. Collectively the forest pumps millions of liters of water daily to the atmosphere." Given the local climate conditions, this evapotranspiration translates into summer rainfall, helping to sustain crops. When the forests disappear, this rainfall declines and crop yields follow.^^21^^\n\nMore and more countries are beginning to recognize the risks associated with deforestation. Among the countries that now have total or partial bans on logging in primary forests are China, New Zealand, the Philippines, Sri Lanka, Thailand, and Viet Nam. Unfortunately, all too often a ban in one country simply shifts the deforestation to others or drives illegal logging. For example, the 1998 ban in China following the Yangtze flooding led to sharp increases in logging in Myanmar (formerly Burma) and Russia, much of it illegal.^^22^^\n\n[[5.2 - Losing Soil]]\n\n[[5.3 - Deteriorating Rangelands]]\n\n[[5.4 - Advancing Deserts]]\n\n[[5.5 - Collapsing Fisheries]]\n\n[[5.6 - Disappearing Plants and Animals]]\n\n[[5.7 - Additional Resources]]\n\n[[5.8 - Notes]]\n\n[[6 - Early Signs of Decline]]
The thin layer of topsoil that covers the planet's land surface is the foundation of civilization. This soil, measured in inches over much of the earth, was formed over long stretches of geological time as new soil formation exceeded the natural rate of erosion. As soil accumulated over the eons, it provided a medium in which plants could grow. In turn, plants protect the soil from erosion. Human activity is disrupting this relationship.\n\nSometime within the last century, soil erosion began to exceed new soil formation in large areas. Perhaps a third or more of all cropland is losing topsoil faster than new soil is forming, thereby reducing the land's inherent productivity. Today the foundation of civilization is crumbling. The seeds of collapse of some early civilizations, such as the Mayans, may have originated in soil erosion that undermined the food supply.\n\nThe accelerating soil erosion over the last century can be seen in the dust bowls that form as vegetation is destroyed and wind erosion soars out of control. Among those that stand out are the Dust Bowl in the U.S. Great Plains during the 1930s, the dust bowls in the Soviet Virgin Lands in the 1960s, the huge one that is forming today in northwest China, and the one taking shape in the Sahelian region of Africa. Each of these is associated with a familiar pattern of overgrazing, deforestation, and agricultural expansion onto marginal land, followed by retrenchment as the soil begins to disappear.^^24^^\n\nTwentieth-century population growth pushed agriculture onto highly vulnerable land in many countries. The overplowing of the U.S. Great Plains during the late nineteenth and early twentieth centuries, for example, led to the 1930s Dust Bowl. This was a tragic era in U.S. history, one that forced hundreds of thousands of farm families to leave the Great Plains. Many migrated to California in search of a new life, a move immortalized in John Steinbeck's //The Grapes of Wrath.//^^25^^\n\nThree decades later, history repeated itself in the Soviet Union. The Virgin Lands Project between 1954 and 1960 centered on plowing an area of grassland for wheat that was larger than the wheatland in Canada and Australia combined. Initially this resulted in an impressive expansion in Soviet grain production, but the success was short-lived as a dust bowl developed there as well.^^26^^\n\nKazakhstan, at the center of this Virgin Lands Project, saw its grainland area peak at just over 25 million hectares around 1980, then shrink to 14 million hectares today. Even on the remaining land, however, the average wheat yield is scarcely 1 ton per hectare, a far cry from the nearly 8 tons per hectare that farmers get in France, Western Europe's leading wheat producer.^^27^^\n\nA similar situation exists in Mongolia, where over the last 20 years half the wheatland has been abandoned and wheat yields have also fallen by half, shrinking the harvest by three fourths. Mongolia - a country almost three times the size of France with a population of 2.6 million - is now forced to import nearly 60 percent of its wheat.^^28^^\n\nDust storms originating in the new dust bowls are now faithfully recorded in satellite images. On January 9, 2005, the National Aeronautics and Space Administration (NASA) released images of a vast dust storm moving westward out of central Africa. This vast cloud of tan-colored dust stretched over some 5,300 kilometers (roughly 3,300 miles). NASA noted that if the storm were relocated to the United States, it would cover the country and extend into the oceans on both coasts.^^29^^\n\nAndrew Goudie, Professor of Geography at Oxford University, reports that Saharan dust storms - once rare - are now commonplace. He estimates they have increased 10-fold during the last half-century. Among the countries in the region most affected by topsoil loss from wind erosion are Niger, Chad, Mauritania, northern Nigeria, and Burkino Faso. In Mauritania, in Africa's far west, the number of dust storms jumped from 2 a year in the early 1960s to 80 a year today.^^30^^\n\nThe Bod√Čl√Č Depression in Chad is the source of an estimated 1.3 billion tons of wind-borne soil a year, up 10-fold from 1947 when measurements began. The 2-3 billion tons of fine soil particles that leave Africa each year in dust storms are slowly draining the continent of its fertility and, hence, its biological productivity. In addition, dust storms leaving Africa travel westward across the Atlantic, depositing so much dust in the Caribbean that they cloud the water and damage coral reefs there.^^31^^\n\nIn China, plowing excesses became common in several provinces as agriculture pushed northward and westward into the pastoral zone between 1987 and 1996. In Inner Mongolia (Nei Monggol), for example, the cultivated area increased by 1.1 million hectares, or 22 percent, during this period. Other provinces that expanded their cultivated area by 3 percent or more during this nine-year span include Heilongjiang, Hunan, Tibet (Xizang), Qinghai, and Xinjiang. Severe wind erosion of soil on this newly plowed land made it clear that its only sustainable use was controlled grazing. As a result, Chinese agriculture is now engaged in a strategic withdrawal in these provinces, pulling back to land that can sustain crop production.^^32^^\n\nWater erosion also takes a toll on soils. This can be seen in the silting of reservoirs and in muddy, silt-laden rivers flowing into the sea. Pakistan's two large reservoirs, Mangla and Tarbela, which store Indus River water for the country's vast irrigation network, are losing roughly 1 percent of their storage capacity each year as they fill with silt from deforested watersheds.^^33^^\n\nEthiopia, a mountainous country with highly erodible soils on steeply sloping land, is losing an estimated 1 billion tons of topsoil a year, washed away by rain. This is one reason Ethiopia always seems to be on the verge of famine, never able to accumulate enough grain reserves to provide a meaningful measure of food security.\n\n[[5.3 - Deteriorating Rangelands]]\n\n[[5.4 - Advancing Deserts]]\n\n[[5.5 - Collapsing Fisheries]]\n\n[[5.6 - Disappearing Plants and Animals]]\n\n[[5.7 - Additional Resources]]\n\n[[5.8 - Notes]]\n\n[[6 - Early Signs of Decline]]
One tenth of the earth's land surface is cropland, but an area twice this size is rangeland - land that is too dry, too steeply sloping, or not fertile enough to sustain crop production. This area - one fifth of the earth's land surface, most of it semi-arid - supports the world's 3.2 billion cattle, sheep, and goats. These livestock are ruminants, animals with complex digestive systems that enable them to digest roughage, converting it into beef, mutton, and milk.^^35^^\n\nAn estimated 180 million people worldwide make their living as pastoralists tending cattle, sheep, and goats. Many countries in Africa depend heavily on their livestock economies for food and employment. The same is true for large populations in the Middle East, Central Asia, Mongolia, northwest China, and much of India. India, with the world's largest cattle herd, depends on cattle not only for milk but also for draft power and fuel.^^36^^\n\nIn other parts of the world, rangelands are exploited by large-scale commercial ranching. Australia, whose land mass is dominated by rangeland, has a flock of 95 million sheep, five times its human population. Grass-based livestock economies also predominate in Argentina, Brazil, Mexico, and Uruguay. And in the Great Plains of North America, semiarid lands that are not suited to growing wheat are devoted to grazing cattle.^^37^^\n\nAlthough public attention often focuses on the role of feedlots in beef production, the share of the world's cattle in feedlots at any one time is a tiny fraction of the vast numbers feeding on grass. Even in the United States, which has most of the world's feedlots, the typical steer is in a feedlot for only a matter of months.\n\nBeef and mutton tend to dominate meat consumption where grazing land is abundant relative to population size. Among the leading beef consumers are the people of Argentina, Brazil, the United States, and Australia. Mutton looms large in diets in New Zealand and Kazakhstan.^^38^^\n\nThese same ruminants that are uniquely efficient at converting roughage into food also supply leather and wool. The world's leather goods and woolen industries, the livelihood of millions, depend on rangelands for raw materials.\n\nWorldwide, almost half of all grasslands are lightly to moderately degraded and 5 percent are severely degraded. The problem is highly visible throughout Africa, the Middle East, Central Asia, and India, where livestock numbers track the growth in human numbers. In 1950, 238 million Africans relied on 273 million livestock. By 2004, there were 887 million people and 725 million livestock. Demands of the livestock industry, a cornerstone of the African economy virtually everywhere, often exceed grassland carrying capacity by half or more.^^39^^\n\nIran - one of the Middle East's most populous countries, with 70 million people - illustrates the pressures facing that region. With more than 9 million cattle and 80 million sheep and goats - the source of wool for its fabled rug-making indus-try - Iran's rangelands are deteriorating from overstocking. In a country where sheep and goats outnumber humans, mutton consumption is widespread. With rangelands now pushed beyond their limits, however, the current livestock population is not sustainable.^^40^^\n\nChina faces similarly difficult challenges. After the economic reforms in 1978 that shifted the responsibility for farming from state-organized production teams to farm families, the government lost control of livestock numbers. As a result, China's cattle, sheep, and goat population spiraled upward. While the United States, a country with comparable grazing capacity, has 95 million cattle, China has 107 million. And while the United States has 7 million sheep and goats, China has 339 million. Concentrated in China's western and northern provinces, sheep and goats are destroying the land's protective vegetation. The wind then does the rest, removing the soil and converting productive rangeland into desert.^^41^^\n\nFodder needs of livestock in nearly all developing countries now exceed the sustainable yield of rangelands and other forage resources. In India, the demand for fodder greatly outpaces the supply, leaving millions of emaciated, unproductive cattle.^^42^^\n\nLand degradation from overgrazing is taking a heavy economic toll in lost livestock productivity. In the early stages of overgrazing, the costs show up as lower land productivity. But as the process continues, it destroys vegetation, leading to erosion and the eventual creation of wasteland and desert. At some point, growth in the livestock population begins to shrink the biologically productive area and thus the earth's capacity to sustain civilization.^^43^^\n\n[[5.4 - Advancing Deserts]]\n\n[[5.5 - Collapsing Fisheries]]\n\n[[5.6 - Disappearing Plants and Animals]]\n\n[[5.7 - Additional Resources]]\n\n[[5.8 - Notes]]\n\n[[6 - Early Signs of Decline]]
Desertification, the process of converting productive land to wasteland through overuse and mismanagement, is unfortunately all too common. Anything that removes protective grass or trees leaves soil vulnerable to wind and water erosion. In the early stages of desertification, the finer particles of soil are removed by the wind, creating the dust storms described earlier. Once the fine particles are removed, then the coarser particles - the sand - are also carried by the wind in localized sand storms.\n\nLarge-scale desertification is concentrated in Asia and Africa - two regions that together contain nearly 4.8 billion of the world's 6.5 billion people. Populations in countries across the top of Africa are being squeezed by the northward advance of the Sahara.^^44^^\n\nIn the vast east-to-west swath of semiarid Africa between the Sahara Desert and the forested regions to the south lies the Sahel, a region where farming and herding overlap. In countries from Senegal and Mauritania in the west to Sudan, Ethiopia, and Somalia in the east, the demands of growing human and livestock numbers are converting more and more land into desert.^^45^^\n\nNigeria, Africa's most populous country, is losing 351,000 hectares of rangeland and cropland to desertification each year. While Nigeria's human population was growing from 33 million in 1950 to 132 million in 2005, a fourfold expansion, its livestock population grew from roughly 6 million to 66 million, an 11-fold increase. With the forage needs of Nigeria's 15 million cattle and 51 million sheep and goats exceeding the sustainable yield of the country's grasslands, the northern part of the country is slowly turning to desert. If Nigeria continues toward 258 million people by 2050, the deterioration will only accelerate.^^46^^\n\nIran is also losing its battle with the desert. Mohammad Jarian, who heads Iran's Anti-Desertification Organization, reported in 2002 that sand storms had buried 124 villages in the southeastern province of Sistan-Baluchistan, forcing their abandonment. Drifting sands had covered grazing areas, starving livestock and depriving villagers of their livelihood.^^47^^\n\nNeighboring Afghanistan is faced with a similar situation. The Registan Desert is migrating westward, encroaching on agricultural areas. A U.N. Environment Programme (UNEP) team reports that "up to 100 villages have been submerged by windblown dust and sand." In the country's northwest, sand dunes are moving onto agricultural land in the upper reaches of the Amu Darya basin, their path cleared by the loss of stabilizing vegetation from firewood gathering and overgrazing. The UNEP team observed sand dunes 15 meters high blocking roads, forcing residents to establish new routes.^^48^^\n\nChina is being affected by desertification more than any other major country. Wang Tao, Director of the Cold and Arid Regions Environmental and Engineering Research Institute, describes the country's accelerating desertification. He reports that from 1950 to 1975 an average of 1,560 square kilometers of land were lost to desert each year. Between 1975 and 1987, this climbed to 2,100 square kilometers a year. From then until the century's end, it jumped to 3,600 square kilometers of land going to desert annually.\n\nChina is now at war. It is not invading armies that are claiming its territory, but expanding deserts. Old deserts are advancing and new ones are forming like guerrilla forces striking unexpectedly, forcing Beijing to fight on several fronts. Wang Tao reports that over the last half-century, some 24,000 villages in northern and western China have been entirely or partly abandoned as a result of being overrun by drifting sand.^^50^^\n\nPeople in China are all too familiar with the dust storms that originate in the northwestern area and western Mongolia, but the rest of the world typically learns about this fast-growing ecological catastrophe from the massive dust storms that travel outside the region. On April 18, 2001, the western United States - from the Arizona border north to Canada - was blanketed with dust. It came from a huge dust storm that originated in northwestern China and Mongolia on April 5. Measuring 1,800 kilometers across when it left China, the storm carried millions of tons of topsoil, a vital resource that will take centuries to replace through natural processes.^^51^^\n\nAlmost exactly one year later, on April 12, 2002, South Korea was engulfed by a huge dust storm from China that left people in Seoul literally gasping for breath. Schools were closed, airline flights were cancelled, and clinics were overrun with patients having difficulty breathing. Retail sales fell. Koreans have come to dread the arrival of what they now call "the fifth season," the dust storms of late winter and early spring.^^52^^\n\nThese two dust storms, among the 10 or so major dust storms that occur each year in China, are one of the externally visible indicators of the ecological catastrophe unfolding in northern and western China. Overgrazing is the principal culprit.^^53^^\n\nA U.S. Embassy report entitled "Desert Mergers and Acquisitions" describes satellite images showing two deserts in north-central China expanding and merging to form a single, larger desert overlapping Inner Mongolia and Gansu provinces. To the west in Xinjiang Province, two even larger deserts - the Taklimakan and Kumtag - are also heading for a merger. Highways running through the shrinking regions between them are regularly inundated by sand dunes.^^54^^\n\nIn Latin America, deserts are expanding in both Brazil and Mexico. In Brazil, where some 58 million hectares of land are affected, economic losses from desertification are estimated at $300 million per year, much of it concentrated in the country's northeast. Mexico, with a much larger share of arid and semiarid land, is even more vulnerable. The degradation of cropland now prompts some 700,000 Mexicans to leave the land each year in search of jobs in nearby cities or in the United States.^^55^^\n\nIn scores of countries, the overgrazing, overplowing, and overcutting that are driving the desertification process are intensifying as the growth in human and livestock numbers continues. Stopping the desertification process from claiming more productive land may now rest on stopping the growth in human and livestock numbers.\n\n[[5.5 - Collapsing Fisheries]]\n\n[[5.6 - Disappearing Plants and Animals]]\n\n[[5.7 - Additional Resources]]\n\n[[5.8 - Notes]]\n\n[[6 - Early Signs of Decline]]
After World War II, accelerating population growth and steadily rising incomes drove the demand for seafood upward at a record pace. At the same time, advances in fishing technologies, including huge refrigerated processing ships that enabled trawlers to exploit distant oceans, enabled fishers to respond to the growing world demand.\n\nIn response, the oceanic fish catch climbed from 19 million tons in 1950 to its historic high of 93 million tons in 1997. This fivefold growth - more than double that of population during this period - raised the wild seafood supply per person worldwide from 7 kilograms in 1950 to a peak of 17 kilograms in 1988. Since then, it has fallen to 14 kilograms.^^56^^\n\nAs population grows and as modern food marketing systems give more people access to these products, seafood consumption is growing. Indeed, the human appetite for seafood is outgrowing the sustainable yield of oceanic fisheries. Today 75 percent of fisheries are being fished at or beyond their sustainable capacity. As a result, many are in decline and some have collapsed. In some fisheries, the breeding stocks have been mostly destroyed.^^57^^\n\nA 2003 landmark study by a Canadian-German science team, published in //Nature//, concluded that 90 percent of the large fish in the oceans had disappeared over the last 50 years. Ransom Myers, a fisheries biologist at Canada's Dalhousie University and lead scientist in this study, says: "From giant blue marlin to mighty blue fin tuna, from tropical groupers to Antarctic cod, industrial fishing has scoured the global ocean. There is no blue frontier left."^^58^^\n\nMyers goes on to say, "Since 1950, with the onset of industrialized fisheries, we have rapidly reduced the resource base to less than 10 percent - not just in some areas, not just for some stocks, but for entire communities of these large fish species from the tropics to the poles."^^59^^\n\nFisheries are collapsing throughout the world. The 500-year-old cod fishery of Canada failed in the early 1990s, putting some 40,000 fishers and fish processors out of work. Fisheries off the coast of New England were not far behind. And in Europe, cod fisheries are in decline, approaching a free fall. Like the Canadian cod fishery, the European ones may have been depleted to the point of no return. Countries that fail to meet nature's deadlines for halting overfishing face fishery decline and collapse.^^60^^\n\nAtlantic stocks of the heavily fished bluefin tuna, where a large specimen headed for Tokyo's sushi restaurants can bring $50,000, have been cut by a staggering 94 percent. It will take years for such long-lived species to recover, even if fishing were to stop altogether. The harvest of the Caspian Sea sturgeon, source of the world's most prized caviar, has fallen from a record 27,700 tons in 1977 to 461 tons in 2000. Overfishing, much of it illegal, is responsible for the dramatic drop.^^61^^\n\nOverfishing is not the only threat to the world's seafood supply. Some 90 percent of fish residing in the ocean rely on coastal wetlands, mangrove swamps, or rivers as spawning areas. Well over half the original area of mangrove forests in tropical and subtropical countries has been lost. The disappearance of coastal wetlands in industrial countries is even greater. In Italy, whose coastal wetlands are the nurseries for many Mediterranean fisheries, the loss is a whopping 95 percent.^^62^^\n\nDamage to coral reefs, breeding grounds for fish in tropical and subtropical waters, is also taking a toll. Between 2000 and 2004, the share of destroyed reefs worldwide expanded from 11 percent to 20 percent. As the reefs deteriorate, so do the fisheries that depend on them.^^63^^\n\nWhile oceanic fisheries face numerous threats, it is overfishing that directly threatens their survival. Oceanic harvests expanded as new technologies evolved, ranging from sonar for tracking schools of fish to vast driftnets that are collectively long enough to circle the earth many times over.\n\nCommercial fishing is now largely an economics of today versus tomorrow. Governments are seeking to protect tomorrow's catches by forcing fishers to keep their ships idle; fishing communities are torn between the need for income today versus the future. Ironically, one reason for excess fleet capacity is long-standing government subsidized loans for investing in new boats and fishing gear.^^64^^\n\nFishing subsidies were based on an unfounded belief that past trends in oceanic harvests could be projected into the future - that past growth meant future growth. The advice of marine biologists, who had long warned that marine harvests would someday reach a limit, was largely ignored.^^65^^\n\nEven among countries accustomed to working together, such as those in the European Union (EU), the challenge of negotiating catch limits at sustainable levels can be difficult. In April 1997, after prolonged negotiations, agreement was reached in Brussels to reduce the fishing capacity of EU fleets by 30 percent for endangered species, such as cod, herring, and sole in the North Sea, and by 20 percent for overfished stocks, such as cod in the Baltic Sea, the bluefin tuna, and swordfish off the Iberian peninsula. The good news was that the EU finally reached agreement on reducing the catch. The bad news was that these cuts were not sufficient to arrest the decline of the region's fisheries.^^66^^\n\nIn January 2001, the EU went further, announcing a complete ban on fishing for cod, haddock, and whiting during the 12-week spring spawning period. With the annual cod catch falling from 300,000 tons during the mid-1980s to 50,000 tons in 2000, this step was a desperate effort to save the fishery. EU officials are all too aware that Canada's vast Newfoundland cod fishery has not recovered since collapsing in 1992, despite the total ban on fishing imposed then. In December 2002, the European Union adopted a still stronger fisheries management plan.^^67^^\n\nWhen some fisheries collapse, it puts more pressure on those that remain. Local shortages quickly become global shortages. With restrictions on the catch in overfished EU waters, the heavily subsidized EU fishing fleet has turned to the west coast of Africa, buying licenses to fish off the coasts of Senegal, Mauritania, Morocco, Guinea-Bissau, and Cape Verde. They are competing there with fleets from Japan, South Korea, Taiwan, Russia, and China. For impoverished countries like Mauritania and Guinea-Bissau, income from fishing licenses can account for up to half of government revenue.^^68^^\n\nUnfortunately for the Africans, their fisheries too are collapsing. In Senegal, where local fishers with small boats once could quickly fill their crafts with fish, on many days now they cannot catch enough fish to cover even their fuel costs. As one Senegalese tribal elder said, "Poverty came to Senegal with these fishing agreements."^^69^^\n\nIf the oceans cannot sustain a catch of more than 95 million tons and if world population continues to grow as projected, the oceanic fish catch per person will likely be declining for the foreseeable future. The generation that came of age during World War II saw the fish catch per person double during their lifetimes. Their grandchildren, the children of today, will experience a steady decline in seafood consumption.^^70^^\n\nThe bottom line is that the growing worldwide demand for seafood can no longer be satisfied by expanding the oceanic fish catch. If it is to be satisfied, it will be by expanding fish farming. But once fish are put in ponds or cages they have to be fed, further intensifying the pressure on land resources.\n\n[[5.6 - Disappearing Plants and Animals]]\n\n[[5.7 - Additional Resources]]\n\n[[5.8 - Notes]]\n\n[[6 - Early Signs of Decline]]
The archeological record shows five great extinctions since life began, each representing an evolutionary setback, a wholesale impoverishment of life on earth. The last of these mass extinctions occurred some 65 million years ago, quite possibly because an asteroid collided with our planet, spewing vast amounts of dust and debris into the atmosphere. The resultant abrupt cooling obliterated the dinosaurs and at least one fifth of all other extant life forms.^^71^^\n\nWe are now in the early stage of the sixth great extinction. Unlike previous extinction events, which were caused by natural phenomena, this one is of human origin. For the first time in the earth's long history, one species has evolved, if that is the right word, to where it can eradicate much of life.\n\nAs various life forms disappear, they diminish the services provided by nature, such as pollination, seed dispersal, insect control, and nutrient cycling. This loss of species is weakening the web of life, and if it continues it could tear huge gaps in its fabric, leading to irreversible changes in the earth's ecosystem.\n\nSpecies of all kinds are threatened by habitat destruction, principally through the loss of tropical rainforests. As we burn off the Amazon rainforest, we are in effect burning one of the great repositories of genetic information. Our descendants may one day view the wholesale burning of this genetic library much as we view the burning of the library in Alexandria in 48 BC.\n\nHabitat alteration from rising temperatures, chemical pollution, or the introduction of exotic species can also decimate both plant and animal species. As human population grows, the number of species with which we share the planet shrinks. We cannot separate our fate from that of all life on the earth. If the rich diversity of life that we inherited is continually impoverished, eventually we will be impoverished as well.^^72^^\n\nThe share of birds, mammals, and fish that are vulnerable or in immediate danger of extinction is now measured in double digits: 12 percent of the world's nearly 10,000 bird species; 23 percent of the world's 4,776 mammal species; and 46 percent of the fish species analyzed.^^73^^\n\nAmong mammals, the 240 known species of primates other than humans are most at risk. The World Conservation Union-IUCN reports that nearly half of these species are threatened with extinction. Some 95 of the world's primate species live in Brazil, where habitat destruction poses a particular threat. Hunting, too, is a threat, particularly in West and Central Africa, where the deteriorating food situation and newly constructed logging roads are combining to create a lively market for "bushmeat."^^74^^\n\nThe bonobos of West Africa, great apes that are smaller than the chimpanzees of East Africa, may be our closest living relative both genetically and in social behavior. But this is not saving them from the bushmeat trade or the destruction of their habitat by loggers. Concentrated in the dense forest of the Democratic Republic of the Congo, their numbers fell from an estimated 100,000 in 1980 to only 3,000 today. In one human generation, 97 percent of the bonobos have disappeared.^^75^^\n\nBirds, because of their high visibility, are a useful indicator of the diversity of life. Of the 9,775 known bird species, roughly 70 percent are declining in number. Of these, an estimated 1,212 species are in imminent danger of extinction. Habitat loss and degradation affect 86 percent of all threatened bird species. For example, 61 bird species have become locally extinct with the extensive loss of lowland rainforest in Singapore. Some once-abundant species may have already dwindled to the point of no return. The great bustard, once widespread in Pakistan and surrounding countries, is being hunted to extinction. Ten of the world's 17 species of penguins are threatened or endangered, potential victims of global warming. Stanford University biologist Çagan Sekercioglu, who led a separate study on the status of the world's birds said, "We are changing the world so much that even birds cannot adapt."^^76^^\n\nA particularly disturbing recent event is the precipitous decline in the populations of Britain's most popular songbirds. Within the last 30 years the populations of well-known species such as the willow warbler, the song thrush, and the spotted flycatcher have fallen 50-80 percent; no one seems to know why, although there is speculation that habitat destruction and pesticides may be playing a role. Without knowing the source of the decline, it is difficult to take actions that will arrest the plunge in numbers.^^77^^\n\nThe threat to fish may be the greatest of all. The principal causes are overfishing, water pollution, and the excessive extraction of water from rivers and other freshwater ecosystems. An estimated 37 percent of the fish species that once inhabited the lakes and streams of North America are either extinct or in jeopardy. Ten North American freshwater fish species have disappeared during the last decade. In semiarid regions of Mexico, 68 percent of native and endemic fish species have disappeared. The situation may be even worse in Europe, where some 80 species of freshwater fish out of a total of 193 are threatened, endangered, or of special concern. Two thirds of the 94 fish species in South Africa need special protection to avoid extinction.^^78^^\n\nThe leatherback turtle, one of the most ancient animal species, and one that can reach a weight of 360 kilograms (800 pounds), also is fast disappearing. Its numbers dropped from 115,000 in 1982 to 34,500 in 1996. At the Playa Grande nesting colony on Costa Rica's west coast, the number of nesting females dropped from 1,367 in 1989 to 117 in 1999. Writing in //Nature//, James Spotila and colleagues warn that "if these turtles are to be saved, immediate action is needed to minimize mortality through fishing and to maximize hatchling production."^^79^^\n\nA World Resources Institute report on coral reefs in the Caribbean notes that 35 percent of Caribbean reefs are threatened by sewage discharge, water-based sediment, and pollution from fertilizer and that 15 percent are threatened by pollution from cruise ship discharges. In economic terms, the Caribbean coral reefs supply goods and services worth at least $3.1 billion per year.^^80^^\n\nThe spectacular coral reefs of the Red Sea, some of the most strikingly beautiful reefs anywhere, are facing extinction due to destructive fishing practices, dredging, sedimentation, and sewage discharge. Anything that reduces sunlight penetration in the sea impairs the growth of corals, leading to die-off. Coral reefs play an important role as nurseries for many forms of sea life, including numerous commercial species of fish.^^81^^\n\nOne of the fastest-growing threats to the diversity of plant and animal life today is the extraordinary agricultural expansion now under way in Brazil as land is cleared to plant soybeans and, more recently, to produce sugarcane for ethanol. Farmers and ranchers are opening up vast areas in the Amazon basin and in the //cerrado//, a Europe-sized savanna-like region south of the Amazon basin. Although there are mechanisms in place that are designed to protect the rich biological diversity of the Amazon, such as the requirement that landowners clear no more than one fifth of their land, the government lacks enforcement capacity.\n\nLike the Amazon, the //cerrado// is also biologically rich, with thousands of endemic plant and animal species. It contains many large mammals, including the maned wolf, giant armadillo, giant anteater, deer, and several large cats - jaguar, puma, ocelot, and jaguarundi. The //cerrado// contains 837 species of birds, including the rhea, a cousin of the ostrich, which grows six feet tall. More than 1,000 species of butterflies have been identified. Conservation International reports that the //cerrado// also contains some 10,000 plant species - at least 4,400 of which are endemic, not found anywhere else.^^83^^\n\nOne of the newer worldwide threats to species, and one that is commonly underestimated, is the introduction of alien species, which can alter local habitats and communities, driving native species to extinction. For example, non-native species may be responsible for 30 percent of the threatened bird species on the IUCN //Red List//. For plants, alien species are implicated in 15 percent of all the listings.^^84^^\n\nEfforts to save wildlife traditionally have centered on the creation of parks or wildlife reserves. Unfortunately, this approach may now be less effective, for if we cannot stabilize climate, there is not an ecosystem on earth that we can save. Everything will change. As the number of species with which we share the planet diminishes, so too does the prospect for our civilization.\n\nIn the new world we are entering, protecting the diversity of life on earth is no longer simply a matter of setting aside tracts of land, fencing them, and calling them parks and preserves. Success in this effort depends on stabilizing both climate and population.\n\nOn the plus side, we now have more information on the state of the earth and the life on it than ever before. While knowledge is not a substitute for action, it is a prerequisite for saving the earth's natural systems - and the civilization that they support.\n\n[[5.7 - Additional Resources]]\n\n[[5.8 - Notes]]\n\n[[6 - Early Signs of Decline]]

In recent years U.N. demographers have stunned the world by announcing that life expectancy among the 750 million people living in sub-Saharan Africa has dropped from 61 to 48 years. This precipitous drop was primarily the result of governments' failure to check the spread of the HIV virus. While industrial countries held HIV infection rates among adults under 1 percent, in some African countries they climbed above 30 percent.^^1^^\n\nFor the first time in the modern era, life expectancy, a seminal indicator of development, has dropped for a large segment of humanity. For the people of sub-Saharan Africa, a failure of leadership is quite literally reversing the march of progress. Is this failure of the political system an anomaly? Or is it an early sign that the scale of emerging problems can overwhelm our political institutions?\n\nDuring the decades following World War II, life expectancy climbed throughout the world with advances in public health, vaccines, antibiotics, and food production. But as the twentieth century drew to a close, the HIV epidemic brought this trend to an end in many countries.^^2^^\n\nToday the variation in life expectancy among countries is wider than at any time in history, ranging from a low of 33 in Swaziland and 37 in Botswana to a high of 82 in Japan and 81 in Iceland. Not surprisingly, life expectancy usually correlates with income levels except where the distribution of income is heavily skewed. In the United States, where income is concentrated among the wealthy and where some 24 million Americans are without health insurance, life expectancy is shorter than in countries like Sweden, Germany, or Japan. Indeed, U.S. life expectancy of 77 years now lags behind the 78 years of Costa Rica, a developing country.\n\nThe stresses in our early twenty-first century civilization take many forms. Economically we see them in the widening income gap between the world's rich and poor. Socially they take the form of the widening gap in education and health care and a swelling flow of environmental refugees as productive land turns to desert and as wells go dry. Politically we see them manifest in conflict over basic resources such as cropland, grazing land, and water. And perhaps most fundamentally, we see the stresses the world is facing in the growing number of failed and failing states.\n\n[[6.1 - Our Socially Divided World]]\n\n[[6.2 - Health Challenge Growing]]\n\n[[6.3 - Throwaway Economy in Trouble]]\n\n[[6.4 - Population and Resource Conflicts]]\n\n[[6.5 - Environmental Refugees on the Rise]]\n\n[[6.6 - Failed States and Terrorism]]\n\n[[6.7 - Additional Resources]]\n\n[[6.8 - Notes]]\n\n[[7 - Eradicating Poverty, Stabilizing Population]]\n\n----\nDownload pdf version of Chapter 6\n\n 22pp. (84 Kb)
The social and economic gap between the world's richest 1 billion people and its poorest 1 billion has no historical precedent. Not only is this gap wide, it is widening. The poorest billion are trapped at a subsistence level and the richest billion are becoming wealthier with each passing year. The economic gap can be seen in the contrasts in nutrition, education, disease patterns, family size, and life expectancy.\n\nWorld Health Organization (WHO) data indicate that roughly 1.2 billion people are undernourished, underweight, and often hungry. At the same time, roughly 1.2 billion people are overnourished and overweight, most of them suffering from excessive caloric intake and exercise deprivation. So while 1 billion people worry whether they will eat, another billion should worry about eating too much.^^4^^\n\nDisease patterns also reflect the widening gap. The billion poorest suffer mostly from infectious diseases - malaria, tuberculosis, dysentery, and AIDS. Malnutrition leaves infants and small children even more vulnerable to such infectious diseases.\n\nUnsafe drinking water takes a heavier toll on those with hunger-weakened immune systems, resulting in millions of fatalities each year. In contrast, among the billion at the top of the global economic scale, it is diseases related to aging and lifestyle excesses, including obesity, smoking, diets rich in fat and sugar, and exercise deprivation, that cause most deaths.^^5^^\n\nEducation levels reflect the deep divide between the rich and the poor. In some industrial countries - for example, Canada and Japan - more than half of all young people now graduate from college with either two- or four-year degrees. By contrast, in developing countries 115 million youngsters of elementary school age are not in school at all. Although five centuries have passed since Gutenberg invented the printing press, nearly 800 million adults are illiterate. Unable to read, they are also excluded from the use of computers and the Internet. Without adult literacy programs, their prospects of escaping poverty are not good.^^6^^\n\nClose to 1 billion people live in countries where population size is essentially stable. But another billion or so live in countries where population is projected to double by 2050. The world's illiterates are concentrated in a handful of the more populous countries, most of them in Asia and Africa. Prominent among these are India, China, Pakistan, Bangladesh, Nigeria, Egypt, Indonesia, and Ethiopia, plus Brazil and Mexico in Latin America. From 1990 to 2000, China and Indonesia made large gains in reducing illiteracy. Other countries also making meaningful progress were Mexico, Nigeria, and Brazil. However, in four other populous countries - Bangladesh, Egypt, Pakistan, and India - the number of illiterates increased.^^7^^\n\nIlliteracy and poverty tend to reinforce each other because illiterate women typically have much larger families than literate women do and because each year of schooling raises earning power by 10-20 percent. In Brazil, for instance, illiterate women have more than six children each on average; literate women have only two. Additionally, illiterate women are trapped by large families and minimal earning power.^^8^^\n\nTo be poor often means to be sick. As with illiteracy, poverty and ill health are closely linked. Health is closely related to access to safe water, something that 1.1 billion people lack. Waterborne diseases claim more than 3 million lives each year, mostly as a result of dysentery and cholera. These and other waterborne diseases take their heaviest toll among children. Infant mortality in affluent societies averages 8 per 1,000 live births; in the 50 poorest countries, it averages 97 per 1,000 - nearly 13 times as high.^^9^^\n\nThe poor and uneducated often do not understand the mechanisms of infectious disease transfer and thus fail to take steps to protect themselves. In addition, those with immune systems weakened by hunger are more vulnerable to common infectious diseases. Poverty also means children are often not vaccinated for routine infectious diseases, even though the cost may be just pennies per child.^^10^^\n\nThe connection between poverty and disease is strong, but it has been broken for most of humanity by economic development. The challenge now is to break this link for that remaining minority who do not have access to safe water, vaccines, education, and basic health care.\n\nHunger is the most visible face of poverty. The U.N. Food and Agriculture Organization estimates that 852 million of the world's people are chronically hungry. They are not getting enough food to achieve full physical and mental development and to maintain adequate levels of physical activity.\n\nThe majority of the underfed and underweight are concentrated in the Indian subcontinent and sub-Saharan Africa - regions that contain 1.4 billion and 750 million people, respectively. Twenty-five years ago, the nutritional status of Asia's population giants, India and China, was similar, but since then China has eliminated most of its hunger, whereas India has made limited progress. During this last quarter-century, China has accelerated the shift to smaller families. While gains in food production in India during this period were absorbed largely by population growth, those in China went mostly to raising individual consumption.^^12^^\n\nMalnutrition takes its heaviest toll among the young, who are most vulnerable during their rapid physical and mental development. In both India and Bangladesh, almost half of all children under five are underweight and malnourished. In Ethiopia, 47 percent of children are undernourished, while in Nigeria the figure is 31 percent - and these are two of Africa's most populous countries.^^13^^\n\nAlthough it is not surprising that those who are underfed and underweight are concentrated in developing countries, it is perhaps surprising that most of them live in rural communities. More often than not, the undernourished are either landless or they live on plots of land so small that they are effectively landless. Those who live on the well-watered plains are usually better nourished. It is those who live on marginal land - land that is steeply sloping or semiarid - who are hungry.^^14^^\n\nThe penalties of being undernourished begin at birth. Gary Gardner and Brian Halweil of Worldwatch Institute cite a U.N. report that estimates 20 million underweight infants are born each year to mothers who also are malnourished. The study indicates that these children suffer lasting effects in the form of "impaired immune systems, neurological damage, and retarded physical growth." David Barker of Britain's University of Southampton observes soberly "that 60 percent of all newborns in India would be in intensive care had they been born in California."^^15^^\n\n[[6.2 - Health Challenge Growing]]\n\n[[6.3 - Throwaway Economy in Trouble]]\n\n[[6.4 - Population and Resource Conflicts]]\n\n[[6.5 - Environmental Refugees on the Rise]]\n\n[[6.6 - Failed States and Terrorism]]\n\n[[6.7 - Additional Resources]]\n\n[[6.8 - Notes]]\n\n[[7 - Eradicating Poverty, Stabilizing Population]]
Health challenges are becoming more numerous as new infectious diseases such as SARS, the West Nile virus, and avian flu emerge. In addition, the accumulation of chemical pollutants in the environment is starting to take a toll. While some infectious diseases, such as malaria and cholera, have been around a long time and are diseases with which health authorities are quite familiar, the health effects of many environmental pollutants are only now being determined.\n\nAmong the leading infectious diseases, malaria claims more than 1 million lives each year, 89 percent of them in Africa. The number who are infected, and often suffer from it most of their lives, is many times greater. Economist Jeffrey Sachs, head of Columbia University's Earth Institute, estimates that reduced worker productivity and other costs associated with malaria are cutting economic growth by a full percentage point in countries with heavily infected populations.^^16^^\n\nAlthough diseases such as malaria and cholera exact a heavy toll, there is no precedent for the number of lives affected by the HIV epidemic. To find anything similar to such a potentially devastating loss of life, we have to go back to the smallpox decimation of Native American communities in the sixteenth century or to the bubonic plague that took roughly a fourth of Europe's population during the fourteenth century. HIV should be seen for what it is - an epidemic of epic proportions that, if not checked soon, could take more lives during this century than were claimed by all the wars of the last century.\n\nSince the human immunodeficiency virus was identified in 1981, this infection has spread worldwide. By 1990, an estimated 10 million people were infected with the virus. By the end of 2004, the number who had been infected climbed to 78 million. Of this total, 38 million have died; 39 million are living with the virus. Twenty-five million HIV-positive people today live in sub-Saharan Africa, but only 500,000 or so are being treated with anti-retroviral drugs. Seven million live in South and Southeast Asia, with over 5 million of them in India alone.^^18^^\n\nInfection rates are climbing. In the absence of effective treatment, the parts of sub-Saharan Africa with the highest infection rates face a staggering loss of life. Adding the heavy mortality from the epidemic to the normal mortality of older adults means that countries like Botswana and Zimbabwe will lose half of their adult populations within a decade.^^19^^\n\nThe HIV epidemic is not an isolated phenomenon. It is affecting every facet of life and every sector of the economy. Food production per person, already lagging in most countries in sub-Saharan Africa, is now falling fast as the number of field workers shrinks. As food production falls, hunger intensifies among the dependent groups of children and the elderly. The downward spiral in family welfare typically begins when the first adult falls victim to the illness - a development that is doubly disruptive because for each person who is sick and unable to work, another adult must care for that person.^^20^^\n\nThe massive loss of young adults to AIDS is already beginning to cut into economic activity. Rising worker health insurance costs in industry are shrinking or even eliminating company profit margins, forcing some firms into the red. In addition, companies are facing increased sick leave, decreased productivity, and the burden of recruiting and training replacements when employees die.^^21^^\n\nEducation is also affected. The ranks of teachers are being decimated by the virus. In 2001, for instance, Zambia lost 815 primary school teachers to AIDS, the equivalent of 45 percent of new teachers trained that year. With students, when one or both parents die, more children are forced to stay home simply because there is not enough money to buy books and to pay school fees. Universities are also feeling the effects. At the University of Durbin in South Africa, for example, 25 percent of the student body is HIV-positive.^^22^^\n\nThe effects on health care are equally devastating. In many hospitals in eastern and southern Africa, a majority of the beds are now occupied by AIDS victims, leaving less space for those with other illnesses. Already overworked doctors and nurses are often stretched to the breaking point. With health care systems now unable to provide even basic care, the toll of traditional disease is also rising. Life expectancy is dropping not only because of AIDS, but also because of the deterioration in health care.^^23^^\n\nThe epidemic is leaving millions of orphans in its wake. Sub-Saharan Africa is expected to have 18.4 million "AIDS orphans" by 2010 - children who have lost at least one parent to the disease. There is no precedent for millions of street children in Africa. The extended family, once capable of absorbing orphaned children, is now itself being decimated by the loss of adults, leaving children, often small ones, to take care of themselves. For some girls, the only option is what has come to be known as "survival sex." Michael Grunwald of the //Washington Post// writes from Swaziland, "In the countryside, teenage Swazi girls are selling sex - and spreading HIV - for $5 an encounter, exactly what it costs to hire oxen for a day of plowing."^^24^^\n\nThe HIV epidemic in Africa is now a development problem, a matter of whether a society can continue to function as needed to support its people. It is a food security problem. It is a national security problem. It is an educational system problem. And it is a foreign investment problem. Stephen Lewis, the U.N. Special Envoy for HIV/AIDS in Africa, says that the epidemic can be curbed and the infection trends can be reversed, but it will take help from the international community. The failure to fully fund the Global Fund to Fight AIDS, Tuberculosis and Malaria, he says, is "mass murder" by complacency.\n\nWriting in the //New York Times//, Alex de Waal, an adviser to the U.N. Economic Commission for Africa and to UNICEF, sums up the effects of the epidemic well: "Just as HIV destroys the body's immune system, the epidemic of HIV and AIDS has disabled the body politic. As a result of HIV, the worst hit African countries have undergone a social breakdown that is now reaching a new level: African societies' capacity to resist famine is fast eroding. Hunger and disease have begun reinforcing each other. As daunting as the prospect is, we will have to fight them together, or we will succeed against neither."^^26^^\n\nWhile the HIV epidemic is currently concentrated in Africa, air and water pollutants are damaging the health of people everywhere. A joint study by the University of California and the Boston Medical Center shows some 200 human diseases, ranging from cerebral palsy to testicular atrophy, linked to pollutants. Other diseases that can be caused by pollutants include an astounding 37 forms of cancer, plus heart disease, kidney disease, high blood pressure, diabetes, dermatitis, bronchitis, hyperactivity, deafness, sperm damage, and Alzheimer's and Parkinson's diseases.^^27^^\n\nIn July 2005, the Environmental Working Group in collaboration with Commonweal released an analysis of umbilical cord blood from 10 randomly selected newborns in U.S. hospitals. They detected a total of 287 chemicals in these tests. "Of the 287 chemicals we detected ... we know that 180 cause cancer in humans or animals, 217 are toxic to the brain and nervous system, and 208 cause birth defects or abnormal development in animal tests." Everyone on the planet shares this "body burden" of toxic chemicals, but infants are at greater risk because they are in the highly vulnerable formative stage of early development.^^28^^\n\nWHO reports an estimated 3 million deaths worldwide each year from air pollutants - three times the number of traffic fatalities. A study in //Lancet// concluded that air pollution claims 40,000 lives per year in France, Austria, and Switzerland, half of them attributable to vehicle emissions. In the United States, air pollution each year claims 70,000 lives, nearly double the 40,000 traffic fatalities.^^29^^\n\nA U.K. research team reports a surprising rise in Alzheimer's and Parkinson's diseases and in motor neuron disease broadly in 10 industrial countries - six in Europe plus the United States, Japan, Canada, and Australia. In England and Wales, deaths from these brain diseases increased from 3,000 per year in the late 1970s to 10,000 in the late 1990s. Over an 18-year period, death rates from these dementias, mainly Alzheimer's, more than tripled for men and nearly doubled for women. This increase in dementia is linked to a rise in the concentration of pesticides, industrial effluents, car exhaust, and other pollutants in the environment.^^30^^\n\nHorror stories of the health effects of uncontrolled industrial pollution in Russia are commonplace. For example, in the industrial town of Karabash in the foothills of the Ural Mountains, children routinely suffer from lead, arsenic, and cadmium poisoning. This translates into congenital defects, neurological disorders, and cancer. Pollutants also impair immune systems.^^31^^\n\nScientists are becoming increasingly concerned about the various effects of mercury, a potent neurotoxin, which now permeates the environment in virtually all countries with coal-burning power plants and many of those with gold mines. Gold miners release an estimated 200,000 pounds of mercury into the Amazon ecosystem each year, and coal-burning power plants release over 100,000 pounds of mercury into the air in the United States. The U.S. Environmental Protection Agency (EPA) reports that "mercury from power plants settles over water ways, polluting rivers and lakes, and contaminating fish."^^32^^\n\nIn 2004, 48 of the 50 states in the United States (all but Alaska and Wyoming) issued a total of 3,221 fish advisories warning against eating fish from local lakes and streams because of their mercury content. EPA research indicates that one out of every six women of childbearing age in the United States has enough mercury in her blood to harm a developing fetus. This means that 360,000 of the 4 million babies born in the country each year may face neurological damage from mercury exposure before birth. In a 2005 study by the Mt. Sinai Center for Children's Health and the Environment, a team of doctors calculated that lower I.Q. levels as a result of mercury exposure in the womb cost the United States $8.7 billion a year in lost earnings potential.^^33^^\n\nNo one knows exactly how many chemicals are manufactured today, but with the advent of synthetic chemicals the number of chemicals in use has climbed to over 100,000. A random blood test of Americans will show measurable amounts of easily 200 chemicals that did not exist a century ago.^^34^^\n\nMost of these new chemicals have not been tested for toxicity. Those that are known to be toxic are included in a list of 667 chemicals whose discharge by industry into the environment must be reported to the EPA. The Toxic Release Inventory (TRI), now accessible on the Internet, also provides information on a community-by-community basis, arming local groups with data needed to evaluate the potential threats to their health and that of the environment. Since the TRI was inaugurated in 1988, reported toxic chemical emissions have declined steadily.^^35^^\n\nAlthough we have been hearing about the carcinogenic effects of pesticides since Rachel Carson launched the environmental era with her book //Silent Spring//, we are not yet adequately dealing with this threat. Since then we have learned a great deal about the health effects from chemicals released into the environment, particularly the endocrine disruptors described by Theo Colborn and her colleagues in //Our Stolen Future//. This family of chemicals disrupts the reproductive and developmental processes not only in humans but in many other species as well.^^36^^\n\n[[6.3 - Throwaway Economy in Trouble]]\n\n[[6.4 - Population and Resource Conflicts]]\n\n[[6.5 - Environmental Refugees on the Rise]]\n\n[[6.6 - Failed States and Terrorism]]\n\n[[6.7 - Additional Resources]]\n\n[[6.8 - Notes]]\n\n[[7 - Eradicating Poverty, Stabilizing Population]]
Another distinctly unhealthy economic trend has been the emergence over the last half-century of a throwaway economy. First conceived following World War II as a way of providing consumers with products, it soon came to be seen also as a vehicle for creating jobs and sustaining economic growth. The more goods produced and discarded, the reasoning went, the more jobs there would be.\n\nWhat sold throwaways was their convenience. For example, rather than washing cloth towels or napkins, consumers welcomed disposable paper versions. Thus we have substituted facial tissues for handkerchiefs, disposable paper towels for hand towels, disposable table napkins for cloth ones, and throwaway beverage containers for refillable ones. Even the shopping bags we use to carry home throwaway products become part of the garbage flow.\n\nThis one-way economy depends on cheap energy. It is also facilitated by what are known in the United States as municipal solid waste management systems. Helen Spiegelman and Bill Sheehan of the Product Policy Institute write that these "have become a perverse public subsidy for the Throwaway Society. More and better waste management at public expense is giving unlimited license to proliferate discards. Today these systems collect 3.4 pounds of product waste a day for each American man, woman, and child - twice as much as in 1960 and ten times as much as 100 years ago. It is time to revamp the system so that it no longer supports the throwaway habit."^^37^^\n\nThe throwaway economy is on a collision course with the earth's geological limits. Aside from running out of landfills near cities, the world is also fast running out of the cheap oil that is used to manufacture and transport throwaway products. Perhaps more fundamentally, there is not enough readily accessible lead, tin, copper, iron ore, or bauxite to sustain the throwaway economy beyond another two or three generations. Assuming an annual 2-percent growth in extraction, U.S. Geological Survey data on current economically recoverable reserves show the world has 18 years of reserves remaining for lead, 20 years for tin, 25 years for copper, 64 years for iron ore, and 69 years for bauxite.^^38^^\n\nThe cost of hauling garbage from cities is rising as nearby landfills fill up and the price of oil climbs. One of the first major cities to exhaust its locally available landfills was New York. When the Fresh Kills landfill, the local destination for New York's garbage, was permanently closed in March 2001, the city found itself hauling garbage to landfill sites in New Jersey, Pennsylvania, and even Virginia - with some of the sites being 300 miles away.^^39^^\n\nGiven the 12,000 tons of garbage produced each day in New York and assuming a load of 20 tons of garbage for each of the tractor-trailers used for the long-distance hauling, some 600 rigs are needed to move garbage from New York City daily. These tractor-trailers form a convoy nearly nine miles long - impeding traffic, polluting the air, and raising carbon emissions. This daily convoy led Deputy Mayor Joseph J. Lhota, who supervised the Fresh Kills shutdown, to observe that getting rid of the city's trash is now "like a military-style operation on a daily basis."^^40^^\n\nFiscally strapped local communities in other states are willing to take New York's garbage - if they are paid enough. Some see it as an economic bonanza. State governments, however, are saddled with increased road maintenance costs, traffic congestion, increased air pollution, noise, potential water pollution from landfill leakage, and complaints from nearby communities.\n\nVirginia Governor Jim Gilmore wrote to Mayor Rudy Giuliani in 2001 complaining about the use of Virginia as a dumping ground. "I understand the problem New York faces," he noted, "but the home state of Washington, Jefferson and Madison has no intention of becoming New York's dumping ground."^^41^^\n\nGarbage travails are not limited to New York City. Toronto, Canada's largest city, closed its last remaining landfill on December 31, 2002, and now ships all its 1.1-million-ton-per-year garbage to Wayne County, Michigan. Ironically, the state of New Jersey, the recipient of some of New York's waste, is now shipping up to 1,000 tons of demolition debris 600 miles - also to Wayne County in Michigan.^^42^^\n\nThe challenge is to replace the throwaway economy with a reduce-reuse-recycle economy. For cities like New York, the challenge should be less what to do with the garbage than how to avoid producing it in the first place.\n\n[[6.4 - Population and Resource Conflicts]]\n\n[[6.5 - Environmental Refugees on the Rise]]\n\n[[6.6 - Failed States and Terrorism]]\n\n[[6.7 - Additional Resources]]\n\n[[6.8 - Notes]]\n\n[[7 - Eradicating Poverty, Stabilizing Population]]
As land and water become scarce, we can expect competition for these vital resources to intensify within societies, particularly between the wealthy and those who are poor and dispossessed. The shrinkage of life-supporting resources per person that comes with population growth is threatening to drop the living standards of millions of people below the survival level. This could lead to unmanageable social tensions that will translate into broad-based conflicts.^^43^^\n\nAccess to land is a prime source of social tension. Expanding world population has cut the grainland per person in half, from 0.23 hectares in 1950 to 0.10 hectares in 2004. One tenth of a hectare is half of a building lot in an affluent U.S. suburb. This ongoing shrinkage of grainland per person makes it more difficult for the world's farmers to feed adequately the 70 million or more people added each year.^^44^^\n\nThe shrinkage in cropland per person not only threatens livelihoods; in largely subsistence societies, it threatens survival itself. Tensions within communities begin to build as landholdings shrink to an area smaller than that needed for survival. The Sahelian zone of Africa, with one of the world's fastest-growing populations, is also an area of spreading conflict.^^45^^\n\nIn troubled Sudan, 2 million people have died and over 4 million have been displaced in the long-standing conflict of more than 20 years between the Muslim north and the Christian south. The conflict in the Darfur region in western Sudan that began in 2003 illustrates the mounting tensions between two Muslim groups - Arab camel herders and black African subsistence farmers. Government troops are backing Arab militias, who are engaging in the wholesale slaughter of black Africans in an effort to drive them off their land, sending them into refugee camps in neighboring Chad. To date, some 140,000 people have been killed in the conflict and another 250,000 have died in the refugee camps of hunger and disease.^^46^^\n\nIn Nigeria, where 132 million people are crammed into an area not much larger than Texas, overgrazing and overplowing are converting grassland and cropland into desert, putting farmers and herders in a war for survival. As Somini Sengupta reported in the //New York Times// in June 2004, "in recent years, as the desert has spread, trees have been felled and the populations of both herders and farmers have soared, the competition for land has only intensified."^^47^^\n\nUnfortunately, the division between herders and farmers is also often the division between Muslims and Christians. The competition for land, amplified by religious differences and combined with a large number of frustrated young men with guns, has created what the //New York Times// described as a "combustible mix" that has "fueled a recent orgy of violence across this fertile central Nigerian state [Kebbi]. Churches and mosques were razed. Neighbor turned against neighbor. Reprisal attacks spread until finally, in mid-May, the government imposed emergency rule."^^48^^\n\nSimilar divisions exist between herders and farmers in northern Mali, the //New York Times// noted, where "swords and sticks have been chucked for Kalashnikovs, as desertification and population growth have stiffened the competition between the largely black African farmers and the ethnic Tuareg and Fulani herders. Tempers are raw on both sides. The dispute, after all, is over livelihood and even more, about a way of life."^^49^^\n\nRwanda has become a classic case study in how mounting population pressure can translate into political tension and conflict. James Gasana, who was Rwanda's Minister of Agriculture and Environment in 1990-92, offers some insights. As the chair of a national agricultural commission in 1990, he had warned that without "profound transformations in its agriculture, [Rwanda] will not be capable of feeding adequately its population under the present growth rate." Although the country's demographers projected major future gains in population, Gasana said in 1990 that he did not see how Rwanda would reach 10 million inhabitants without social disorder "unless important progress in agriculture, as well as other sectors of the economy, were achieved."^^50^^\n\nGasana's warning of possible social disorder was prophetic. He further described how siblings inherited land from their parents and how, with an average of seven children per family, plots that were already small were fragmented further. Many farmers tried to find new land, moving onto steeply sloping mountains. By 1989, almost half of Rwanda's cultivated land was on slopes of 10 to 35 degrees, land that is universally considered uncultivable.^^51^^\n\nIn 1950, Rwanda's population was 2.4 million. By 1993, it was 7.5 million, making it the most densely populated country in Africa. As population grew, so did the demand for firewood. By 1991, the demand was more than double the sustainable yield of local forests. As trees disappeared, straw and other crop residues were used for cooking fuel. With less organic matter in the soil, land fertility declined.^^52^^\n\nAs the health of the land deteriorated, so did that of the people dependent on it. Eventually there was simply not enough food to go around. A quiet desperation developed. Like a drought-afflicted countryside, it could be ignited with a single match. That match ignited with the crash of a plane on April 6, 1994, shot down as it approached the capital of Kigali, killing President Juvenal Habyarimana. The crash unleashed an organized attack by Hutus, leading to an estimated 800,000 deaths of Tutsis and moderate Hutus in 100 days. In some villages, whole families were slaughtered lest there be survivors to claim the family plot of land.^^53^^\n\nMany other African countries, largely rural in nature, are on a demographic track similar to Rwanda's. Tanzania's population of 38 million in 2005 is projected to increase to 67 million by 2050. Eritrea, where the average family has six children, is projected to grow from 4 million to 11 million by 2050. In the Democratic Republic of the Congo, the population is projected to triple, going from 58 million to 177 million.^^54^^\n\nAfrica is not alone. In India, tension between Hindus and Muslims is never far below the surface. As each successive generation further subdivides already small plots, pressure on the land is intense. The pressure on water resources is even greater.\n\nWith India's population projected to grow from 1.1 billion in 2005 to 1.6 billion in 2050, a collision between rising human numbers and shrinking water supplies seems inevitable. The risk is that India could face social conflicts that would dwarf those in Rwanda. As Gasana notes, the relationship between population and natural systems is a national security issue, one that can spawn conflicts along geographic, tribal, ethnic, or religious lines.^^55^^\n\nDisagreements over the allocation of water among countries that share river systems is a common source of international political conflict, especially where populations are outgrowing the flow of the river. Nowhere is this potential conflict more stark than among Egypt, Sudan, and Ethiopia in the Nile River valley. Agriculture in Egypt, where it rarely rains, is wholly dependent on water from the Nile. Egypt now gets the lion's share of the Nile's water, but its current population of 74 million is projected to reach 126 million by 2050, thus greatly expanding the demand for grain and for water. Sudan, whose 36 million people also depend heavily on food produced with Nile water, is expected to have 67 million by 2050. And the number of Ethiopians, in the country that controls 85 percent of the river's headwaters, is projected to expand from 77 million to 170 million.^^56^^\n\nSince there is already little water left in the Nile when it reaches the Mediterranean, if either Sudan or Ethiopia takes more water, Egypt will get less, making it increasingly difficult to feed an additional 52 million people. Although there is an existing water rights agreement among the three countries, Ethiopia receives only a minuscule share of water. Given its aspirations for a better life, and with the headwaters of the Nile being one of its few natural resources, Ethiopia will undoubtedly want to take more. With income per person averaging only $860 a year in Ethiopia compared with nearly $4,300 in Egypt, it is hard to argue that Ethiopia should not get more of the Nile water.^^57^^\n\nTo the north, Turkey, Syria, and Iraq share the waters of the Tigris and Euphrates river system. Turkey, controlling the headwaters, is developing a massive project on the Tigris to increase the water available for irrigation and power. Syria and Iraq, which are both projected to double their respective populations of 19 million and 29 million, are concerned because they too will need more water.^^58^^\n\nIn the Aral Sea basin in Central Asia, there is an uneasy arrangement among five countries over the sharing of the two rivers, the Amu Darya and the Syr Darya, that drain into the sea. The demand for water in Kazakhstan, Kyrgyzstan, Tajikistan, Turkmenistan, and Uzbekistan already exceeds the flow of the two rivers by 25 percent. (See Chapter 3.) Turkmenistan, which is upstream on the Amu Darya, is planning to develop another half-million hectares of irrigated agriculture. Racked by insurgencies, the region lacks the cooperation needed to manage its scarce water resources. On top of this, Afghanistan, which controls the headwaters of the Amu Darya, plans to use some of the water for its development. Geographer Sarah O'Hara of the University of Nottingham, who studies the region's water problems, says, "We talk about the developing world and the developed world, but this is the deteriorating world."^^59^^\n\n[[6.5 - Environmental Refugees on the Rise]]\n\n[[6.6 - Failed States and Terrorism]]\n\n[[6.7 - Additional Resources]]\n\n[[6.8 - Notes]]\n\n[[7 - Eradicating Poverty, Stabilizing Population]]
As natural systems deteriorate, people are forced to migrate, sometimes to other countries. In mid-October 2003, Italian authorities discovered a boat carrying refugees from Africa bound for Italy. Adrift for more than two weeks and without fuel, food, and water, many of the passengers had died. At first the dead were tossed overboard. But after a point, the remaining survivors lacked the strength to hoist the bodies over the side. The dead and the living sharing the boat resembled what a rescuer described as "a scene from Dante's //Inferno//."^^60^^\n\nThe refugees were believed to be Somalis who had embarked from Libya, but they would not reveal their country of origin. We do not know whether they were political, economic, or environmental refugees. Failed states like Somalia produce all three. We do know that Somalia is an ecological basket case, with overpopulation, overgrazing, and desertification already destroying its pastoral economy.\n\nFor Central American countries, including Honduras, Guatemala, Nicaragua, and El Salvador, Mexico is often the gateway to the United States. In 2003, Mexican authorities arrested and deported some 147,000 illegal immigrants, up from roughly 120,000 the previous year.^^62^^\n\nIn the city of Tapachula on the Guatemala-Mexico border, young men in search of jobs wait along the tracks for a slow-moving freight train moving through the city en route to the north. Some make it onto the train. Others do not. The Jes√ļs el Buen Pastor refuge is home to 25 amputees who lost their grip and fell under the train while trying to board. For these young men, says Olga S√°nchez Mart√≠nez, the director of the refuge, this is the "end of their American dream." A local priest, Flor Mar√≠a Rigoni, calls the migrants attempting to board the trains "the kamikazes of poverty."^^63^^\n\nEnvironmental refugees also flow to the United States from Haiti, a widely recognized ecological disaster. In a rural economy where the land is stripped of vegetation and the soil is washing into the sea, the people are not far behind. Many drown in rough waters when attempting to make the trip to Florida in small craft not designed for the high seas.^^64^^\n\nToday, bodies washing ashore in Italy, Spain, and Turkey are a daily occurrence, the result of desperate acts by desperate people. And each day Mexicans risk their lives in the Arizona desert trying to reach jobs in the United States. Some 400 to 600 Mexicans leave rural areas every day, abandoning plots of land too small or too eroded to make a living. They either head for Mexican cities or try to cross illegally into the United States. Many of those who try to cross the Arizona desert perish in its punishing heat - scores of bodies are found along the Arizona border each year.^^65^^\n\nAlthough the modern world has extensive experience with political and economic refugees, we are now seeing a swelling flow of refugees driven from their homes by environmental pressures. This harkens back to the Dust Bowl era some 70 years ago, when nearly 3 million Americans were displaced.^^66^^\n\nThe United States is again contending with environmental refugees but now for different reasons. In Alaska, where the temperature rise in recent decades of 2-4 degrees Celsius (4-7 degrees Fahrenheit) is perhaps as great as anywhere in the world, thousands of indigenous peoples will almost certainly be forced to evacuate their villages as a result of ice melting and flooding. Newtok, a village of 340 Yupik Eskimos on Alaska's west coast, is being overrun by a swelling torrent of ice melt water from the Ninglick River. An engineering study estimated the cost of relocating the village at a minimum of $50 million - or $150,000 per villager. If the Newtok Indians do not move, they risk drowning in the floodwater. Although relocating villages is not a simple matter, there are 23 other Alaskan villages waiting to be relocated.^^67^^\n\nWith the vast majority of the nearly 3 billion people to be added to the world by 2050 living in countries where water tables are already falling, water refugees are likely to become commonplace. They will be most common in arid and semiarid regions where populations are outgrowing the water supply and sinking into hydrological poverty. Villages in northwestern India are being abandoned as aquifers are depleted and people can no longer find water. Millions of villagers in northern and western China and in parts of Mexico may have to move because of a lack of water.^^68^^\n\nAdvancing deserts are also displacing people, squeezing expanding populations into an ever smaller geographic area. Whereas the U.S. Dust Bowl displaced a few million people, the abandonment or partial depopulation of 24,000 villages in China's dust bowl provinces is displacing tens of millions.^^69^^\n\nIn Iran, villages abandoned because of spreading deserts or a lack of water already number in the thousands. In the vicinity of Damavand, a small town within an hour's drive of Tehran, 88 villages have been abandoned. And as the desert takes over in Nigeria, farmers and herders are forced to move, squeezed into a shrinking area of productive land. Desertification refugees typically end up in cities, many in squatter settlements. Many more migrate abroad.^^70^^\n\nAnother upcoming source of refugees, potentially a huge one, is rising seas. The largest potential displacement would come in low-lying Bangladesh, where even a 1-meter rise in sea level would not only inundate half of the country's riceland but would also force the relocation of easily 40 million people. In a densely populated country with 142 million people, internal relocation would not be easy. But where else can they go? How many countries would accept even a million Bangladeshi refugees displaced by rising sea level? Other Asian countries with rice-growing river deltas and floodplains, including China, India, Indonesia, Pakistan, the Philippines, South Korea, Thailand, and Viet Nam, could also suffer a mass exodus from rising seas.^^71^^\n\nThe refugee flows from falling water tables and expanding deserts are just beginning. How large these flows and those from rising seas will become remains to be seen. But the numbers could be huge, offering yet another reason for stabilizing climate and population.\n\n[[6.6 - Failed States and Terrorism]]\n\n[[6.7 - Additional Resources]]\n\n[[6.8 - Notes]]\n\n[[7 - Eradicating Poverty, Stabilizing Population]]
After a half-century of forming new states from former colonies and from the breakup of the Soviet Union, the international community is now focusing on the disintegration of states. The term "failed states" is now part of our working vocabulary, describing countries where there is no longer a central government. As one study observes, "Failed states have made a remarkable odyssey from the periphery to the very center of global politics."^^72^^\n\nRecognizing this increasingly common phenomenon, various groups concerned with economic development and international affairs have begun to identify failing or failed states and the indicators associated with their failure. The World Bank, for example, has constructed a list of 30 "low-income countries under stress." Motivated by a similar concern, the United Kingdom's Department for International Development has identified 46 "fragile" states. The U.S. Central Intelligence Agency has constructed a list of 20 failing states. Most recently, the Fund for Peace and the Carnegie Endowment for International Peace have worked together to identify a list of 60 states, ranking them according to "their vulnerability to violent internal conflict."^^73^^\n\nThis analysis, published in //Foreign Policy//, is based on 12 social, economic, political, and military indicators. It puts C√īte d'Ivoire at the top of the list of failed states, followed by the Democratic Republic of the Congo, Sudan, Iraq, Somalia, Sierra Leone, Chad, Yemen, Liberia, and Haiti. Next in line are three countries that have been much in the news in recent years: Afghanistan, Rwanda, and North Korea.^^74^^\n\nFive oil-exporting countries make the top 60 list, including the two largest exporters and producers - Saudi Arabia (forty-fifth on the list) and Russia (fifty-ninth) - plus Venezuela (twenty-first), Indonesia (forty-sixth), and Nigeria (fifty-fourth). Two countries with nuclear arsenals are also on the list: Pakistan and Russia.^^75^^\n\nThe three top indicators used in constructing the //Foreign Policy// scorecard are uneven development, the loss of governmental legitimacy, and demographic pressure. Uneven development typically means that a small segment of the population is accumulating wealth while much of the society may be suffering a decline in living conditions. This unevenness, often associated with political corruption, creates unrest and can lead to civil conflict.^^76^^\n\nGovernments that fail to effectively manage emerging issues and provide basic services are seen as useless. This often causes segments of the population to shift their allegiance to warlords, tribal chieftains, or religious leaders. A loss of political legitimacy is an early sign of state decline.^^77^^\n\nThe third top indicator is demographic pressure. All the countries in the top 20 on the //Foreign Policy// list have fast-growing populations. In many that have experienced rapid population growth for several decades, governments are suffering from demographic fatigue, unable to cope with the steady shrinkage in per capita cropland and fresh water supplies or to build schools fast enough for the swelling ranks of children.^^78^^\n\nForeign investment drying up and a resultant rise in unemployment are also part of the decline syndrome. An earlier study by Population Action International showed that one of the key indicators of political instability in a society is the number of unemployed young men, a number that is high in countries at the top of the //Foreign Policy// article list.^^79^^\n\nAnother characteristic of failing states is a deterioration of the physical infrastructure - roads and power, water, and sewage systems. Care for natural systems is also neglected as people struggle to survive. Forests, grasslands, and croplands deteriorate, creating a downward economic spiral.^^80^^\n\nAmong the most conspicuous indications of state failure is a breakdown in law and order and a related loss of personal security. In Haiti, armed gangs rule the streets. Kidnapping for ransom of local people who are lucky enough to be among the 30 percent of the labor force that is employed is commonplace. In Afghanistan it is the local warlords, not the central government, that control the country outside of Kabul. Somalia, which now exists only on maps, is ruled by tribal leaders, each claiming a piece of what was once a country.\n\nSome of these countries are involved in long-standing civil conflicts. The Democratic Republic of the Congo, occupying a large part of the Congo River basin in the heart of Africa, has been the site of an ongoing civil conflict for six years, a conflict that has claimed 3.8 million lives and driven millions more from their homes. According to the International Rescue Committee, for each violent death in this conflict there are 62 nonviolent deaths related to it, including deaths from hunger, respiratory illnesses, diarrhea, and other diseases.^^82^^\n\nSome potential sources of instability are taking the world into uncharted territory. In sub-Saharan Africa, where HIV infection rates sometimes exceed 30 percent of all adults, there will be millions of orphans in the years ahead, as noted earlier. With the number of orphans overwhelming society's capacity to care for them, many will become street children. Growing up without parental guidance and appropriate role models, and with their behavior shaped by the desperation of survival, these orphans will become a new threat to stability and progress.^^83^^\n\nFailing states are of growing international concern because they are a source of terrorists, drugs, weapons, and refugees. Not only was Afghanistan a training ground for terrorists, but it quickly became, under the Allied occupation, the world's leading supplier of heroin. Refugees from Rwanda, including thousands of armed soldiers, contributed to the destabilization of the Congo. As //The Economist// notes, "Like a severely disturbed individual, a failed state is a danger not just to itself, but to those around it and beyond."^^84^^\n\nIn many countries, the United Nations or other internationally organized peacekeeping forces are trying to keep the peace, often unsuccessfully. Among the countries with U.N. peacekeeping forces are the Democratic Republic of the Congo, Sierra Leone, and Liberia. Other countries with multinational peacekeeping forces include Afghanistan, Haiti, and Sudan. All too often these are token forces, not nearly large enough to assure stability.\n\nCountries like Haiti and Afghanistan are surviving today because they are on international life-support systems. Economic assistance - including, it is worth noting, food aid - is helping to sustain them. But there is not now enough assistance to overcome the reinforcing trends of deterioration and replace them with state stability and sustained economic progress.^^86^^\n\n[[6.7 - Additional Resources]]\n\n[[6.8 - Notes]]\n\n[[7 - Eradicating Poverty, Stabilizing Population]]

The ''60th Annual DPI/NGO Conference'', to be held at ''United Nations Headquarters'' from September 5-7, 2007, has adopted the theme ''Climate Change: How It Impacts Us All''. Approximately 2,000 representatives of Non-Governmental Organizations (NGOs) from throughout the world will participate. This web site is being developed by an open partnership that includes the [[Networking Sub-Committee]] of the [[DPI/NGO Conference Planning Committee]] of the [[NGO/DPI Executive Committee]] and the [[Information and Communications Sub-Committee]] of the [[NGO Committee on Education]] of [[CONGO|Conference Of NGOs]] - the Conference Of Non-Governmental Organizations in Consultative Relationship with the United Nations - in support of preparations for, participation in, and follow-up to the conference.\n\nThe ''60th Annual DPI/NGO Conference'' will be the last to be held at UN Headquarters for several years, and this site is being developed with the vision of building a prototype of an online framework that would facilitate broad-based NGO participation in future Annual DPI/NGO Conferences.\n
The new century began on an inspiring note when the countries that belong to the United Nations adopted the goal of cutting the number of people living in poverty in half by 2015. And as of 2005, the world is ahead of schedule for reaching this goal. There are two big reasons for this: China and India. China's economic growth of 9 percent a year over the last quarter-century and India's acceleration to close to 6 percent a year over the last decade are together lifting hundreds of millions out of poverty.\n\nIn China, the number living in poverty dropped from 648 million in 1981 to 218 million in 2001, the greatest reduction in poverty in history. India is also making impressive progress on the economic front. Under the dynamic new leadership of Prime Minister Manmohan Singh, who took office in 2004, and his skilled team, poverty is being attacked directly by upgrading infrastructure at the village level. Targeted investments are aimed at the poorest of the poor. If the international community actively reinforces this effort in reform-minded India, hundreds of millions more could be lifted out of poverty.\n\nIt is time for the international community to make sure that India has the resources needed to maintain the momentum it has built. With India now on the move economically, the world can then begin to concentrate intensively on the remaining poverty concentrated in sub-Saharan Africa and a scattering of smaller countries in Latin America and Central Asia.\n\nSeveral countries in Southeast Asia are making impressive gains as well, including Thailand, Viet Nam, and Indonesia. Barring any major economic setbacks, these gains in Asia virtually ensure that the U.N. Millennium Development Goal for reducing poverty by 2015 will be reached.^^3^^\n\nThat is the good news. The bad news is that sub-Saharan Africa - with 750 million people - is sliding deeper into poverty. Hunger, illiteracy, and disease are on the march, offsetting some of the gains in China and India. Africa, selected as a focus of discussion at the G-8 meeting in July 2005, needs special attention.^^4^^\n\nIn an increasingly integrated world, eradicating poverty and stabilizing population are national security issues. Slowing population growth helps eradicate poverty and its distressing symptoms, and, conversely, eradicating poverty helps slow population growth. With time running out, the urgency of moving simultaneously on both fronts is clear.\n\nIn addition to the goal of cutting the number of people living in poverty in half by 2015, the other U.N. Millennium Development Goals include cutting the number who are hungry in half, achieving universal primary school education, providing access to safe drinking water for all, and reversing the spread of infectious diseases, especially HIV and malaria. Closely related to these are the goals of reducing maternal mortality by three fourths and under-five child mortality by two thirds.^^5^^\n\nWhile goals for cutting poverty in half by 2015 appear to be running slightly ahead of schedule, those for halving the number of hungry are not. The number of children with a primary school education appears to be increasing substantially, however, largely on the strength of progress in India. And mortality of children under five fell from 15 million in 1980 to 11 million in 2003 and is expected to continue falling.^^6^^\n\n[[7.1 - Universal Basic Education]]\n\n[[7.2 - Stabilizing Population]]\n\n[[7.3 - Better Health for All]]\n\n[[7.4 - Curbing the HIV Epidemic]]\n\n[[7.5 - Reducing Farm Subsidies and Debt]]\n\n[[7.6 - A Poverty-Eradication Budget]]\n\n[[7.7 - Additional Resources]]\n\n[[7.8 - Notes]]\n\n[[8 - Restoring the Earth]]\n\n----\nDownload pdf version of Chapter 7\n\n 21pp. (88 Kb)
One way of narrowing the gap between rich and poor is by ensuring universal education. This means ensuring that 115 million children who do not attend school are able to. Children without any formal education are starting life with a severe handicap, one that almost ensures they will remain in abject poverty and that the gap between the poor and the rich will continue to widen. In an increasingly integrated world, this widening gap becomes a source of instability. Nobel Prize-winning economist Amartya Sen focuses the point nicely: "Illiteracy and innumeracy are a greater threat to humanity than terrorism."^^7^^\n\nRecognizing the central role of education in human progress, the United Nations set universal primary education by 2015 as one of its Millennium Development Goals. The World Bank has taken the lead with its Education for All plan, where any country with a well-designed plan to achieve universal primary education is eligible for financial support. The three principal requirements are that a country submit a sensible plan to reach universal basic education, commit a meaningful share of its own resources to the plan, and have transparent budgeting and accounting practices. If fully implemented, all children in poor countries would get a primary school education by 2015.^^8^^\n\nThe benefits of education are many, particularly for women. The achievement level of children correlates closely with the educational level of their mothers. Children of educated mothers are better nourished not necessarily because the family income is higher but because their mother's better understanding of nutrition leads to a better choice of foods and healthier methods of preparation. Educating women is the key to breaking the poverty cycle.^^9^^\n\nThe education of girls leads to smaller families. In every society for which data are available, fertility falls as female educational levels rise. And mothers with at least five years of school lose fewer infants during childbirth or early illnesses than their less educated peers do. Among other things, these women can read the instructions on medications and they have a better understanding of how to take care of themselves during pregnancy. Economist Gene Sperling concluded in a 2001 study of 72 countries that "the expansion of female secondary education may be the single best lever for achieving substantial reductions in fertility."^^10^^\n\nBasic education increases agricultural productivity. Agricultural extension services that cannot use printed materials to disseminate information on improved agricultural practices are severely handicapped. So too are farmers who cannot read the instructions on a bag of fertilizer. The inability to read instructions on a pesticide container can be life-threatening.\n\nAt a time when HIV is spreading throughout the world, schools provide the institutional means to educate young people about the risks of infection. The time to inform and educate children about the virus and about the lifestyles that foster its spread is when they are young, not when they are already infected. Young people can also be mobilized to conduct educational campaigns among their peers.\n\nOne great need in developing countries, particularly those where the ranks of teachers are being decimated by AIDS, is more teacher training. Providing scholarships for promising students from poor families to attend training institutes in exchange for a commitment to teach for a fixed period of time, say five years, could be a highly profitable investment. It would help ensure that the human resources are available to reach the universal primary education goal, and it would also open the door for an upwelling of talent from the poorest segments of society.\n\nGene Sperling believes that every plan should provide for getting to the hardest-to-reach segments of society, especially poor girls in rural areas. He notes that Ethiopia has pioneered this with Girls Advisory Committees. Representatives of these groups go to the parents who are seeking early marriage for their daughters and encourage them to keep their children in school. Some countries, Brazil and Bangladesh among them, actually provide small scholarships for girls where needed, thus helping girls from poor families get a basic education.^^11^^\n\nAs the world becomes ever more integrated economically, its nearly 800 million illiterate adults are severely handicapped. This deficit can perhaps best be dealt with by launching adult literacy programs, relying heavily on volunteers. The international community could offer seed money to provide educational materials and outside advisors where needed. Bangladesh and Iran, both of which have successful adult literacy programs, can serve as models.^^12^^\n\nThe World Bank estimates that external funding of roughly $12 billion a year would be needed to achieve universal primary education in the more than 80 countries that are unlikely to reach this goal by 2015. At a time when education gives children access not only to books but also to personal computers and the vast information resources of the Internet, having children who never go to school is no longer acceptable.^^13^^\n\nFew incentives to get children in school are as effective as a school lunch program, especially in the poorest countries. Since 1946, every child in public school in the United States has had access to a school lunch program, ensuring one good meal each day. There is no denying the benefits of this national program that has continued uninterrupted for so many years. George McGovern and Robert Dole, both former members of the U.S. Senate agricultural committee and former candidates for President, want to provide school lunch programs in all the world's poorest countries.^^14^^\n\nChildren who are ill or hungry miss many days of school. And even when they can attend, they do not learn as well. Jeffrey Sachs notes, "Sick children often face a lifetime of diminished productivity because of interruptions in schooling together with cognitive and physical impairment." But when school lunch programs are launched in low-income countries, school enrollment jumps. The children's attention span increases. Their academic performance goes up. Fewer days are missed, and children spend more years in school.^^15^^\n\nGirls benefit especially. Drawn to school by the lunch, they stay in school longer, marry later, and have fewer children. This is a win-win-win situation. Adopting a school lunch program in the 44 lowest-income countries would cost an estimated $6 billion per year beyond what the United Nations is now spending in its efforts to reduce hunger.^^16^^\n\nGreater efforts are also needed to improve nutrition before children even get to school age, so they can benefit from school lunches later. George McGovern notes that "a women, infants and children (WIC) program, which offers nutritious food supplements to needy pregnant and nursing mothers," should also be available in the poor countries. Based on 25 years of experience, it is clear that the U.S. WIC program has been enormously successful in improving nutrition, health, and the development of preschool children from low-income families. If this were expanded to reach pregnant women, nursing mothers, and small children in the 44 poorest countries, it would help eradicate hunger among millions of small children at a stage in their lives when it could make a huge difference.^^17^^\n\nThese efforts, though costly, are not expensive compared with the annual losses in productivity from hunger. McGovern and Dole think that this initiative can help "dry up the swamplands of hunger and despair that serve as potential recruiting grounds for terrorists." In a world where vast wealth is accumulating among the rich, it makes little sense for children to be going to school hungry.\n\n[[7.2 - Stabilizing Population]]\n\n[[7.3 - Better Health for All]]\n\n[[7.4 - Curbing the HIV Epidemic]]\n\n[[7.5 - Reducing Farm Subsidies and Debt]]\n\n[[7.6 - A Poverty-Eradication Budget]]\n\n[[7.7 - Additional Resources]]\n\n[[7.8 - Notes]]\n\n[[8 - Restoring the Earth]]
Some 42 countries now have populations that are either essentially stable or declining slowly. In countries with the lowest fertility rates, including Japan, Russia, Germany, and Italy, populations will likely decline over the next half-century.\n\nA larger group of countries has reduced fertility to the replacement level or just below. They are headed for population stability after large groups of young people move through their reproductive years. Included in this group are China, the world's most populous country, and the United States, the third most populous one. A third group of countries is projected to more than double their populations by 2050, including Ethiopia, the Democratic Republic of the Congo, and the Sudan.^^20^^\n\nU.N. projections show world population growth under three different assumptions about fertility levels. The medium projection, the one most commonly used, has world population reaching 9.1 billion by 2050. The high one reaches 10.6 billion. The low projection, which assumes that the world will quickly move below replacement-level fertility to 1.6 children per couple, has population peaking at 7.8 billion in 2041 and then declining. If the goal is to eradicate poverty, hunger, and illiteracy, we have little choice but to strive for the lower projection.^^21^^\n\nSlowing world population growth means that all women who want to plan their families should have access to the family planning services they need. Unfortunately, at present 201 million couples cannot obtain the services they need to limit the size of their families. Filling the family planning gap may be the most urgent item on the global agenda. The benefits are enormous and the costs are minimal.^^22^^\n\nThe good news is that countries that want to help couples to reduce the size of their families quickly can do so. My colleague Janet Larsen writes that in just one decade Iran dropped its population growth rate from one of the world's fastest to one of the lowest in the developing world. When Ayatollah Khomeini assumed leadership in Iran in 1979, he immediately dismantled the family planning programs that the Shah had put in place in 1967 and instead advocated large families. At war with Iraq between 1980 and 1988, Khomeini wanted large families to increase soldiers for Islam. His goal was an army of 20 million. In response to his pleas, fertility levels climbed, pushing Iran's population growth up to a peak of 4.2 percent in the early 1980s, a level approaching the biological maximum. As this enormous growth began to burden the economy and the environment, the country's leaders realized that overcrowding, environmental degradation, and unemployment were undermining Iran's future.^^23^^\n\nIn 1989 the government did an about-face and Iran restored its family planning program. In May 1993, a national family planning law was passed. The resources of several government ministries, including education, culture, and health, were mobilized to encourage smaller families. Iran Broadcasting was given responsibility for raising awareness of population issues and of the availability of family planning services. Some 15,000 "health houses" or clinics were established to provide rural populations with health and family planning services.^^24^^\n\nReligious leaders were directly involved in what amounted to a crusade for smaller families. Iran introduced a full panoply of contraceptive measures, including male sterilization - a first among Muslim countries. All forms of birth control, including contraceptives such as the pill and sterilization, were free of charge. In fact, Iran became a pioneer - the only country to require couples to take a class on modern contraception before receiving a marriage license.^^25^^\n\nIn addition to the direct health care interventions, a broad-based effort was launched to raise female literacy, boosting it from 25 percent in 1970 to more than 70 percent in 2000 - an impressive achievement. Female school enrollment increased from 60 to 90 percent. Television was used to disseminate information on family planning throughout the country, taking advantage of the 70 percent of rural households with TV sets.\n\nAs a result of the impressive effort launched in 1989, family size in Iran dropped from seven children to fewer than three. From 1987 to 1994, Iran cut its population growth rate by half. Its overall population growth rate of 1.2 percent in 2004 is only slightly higher than that of the United States.^^26^^\n\nIf a country like Iran, with a strong tradition of Islamic fundamentalism, can move quickly toward population stability, other countries can too. Countries everywhere have little choice but to strive for an average of two children per couple. There is no feasible alternative. Any population that increases or decreases continually over the long term is not sustainable. The time has come for world leaders - including the Secretary-General of the United Nations, the President of the World Bank, and the President of the United States - to publicly recognize that the earth cannot easily support more than two children per family.\n\nThe costs of providing reproductive health and family planning services are not that high. At the International Conference on Population and Development held in 1994 in Cairo, it was estimated that a fully funded population and reproductive health program for the next 20 years would cost roughly $17 billion annually by 2000 and $22 billion by 2015. Developing countries agreed to cover two thirds of this, while industrial countries were to cover one third. Although we have passed the 10-year anniversary of the Cairo conference, developing countries have fallen short of their pledge by roughly 20 percent, while donor countries have fallen short by half, leaving a combined gap of roughly $6.6 billion per year.^^27^^\n\nThe United Nations estimated that meeting the needs of the 201 million women who do not have access to effective contraception could each year prevent 52 million unwanted pregnancies, 22 million induced abortions, and 1.4 million infant deaths. Some 142,000 pregnancy-related deaths could also be prevented. The costs to society of not filling the family planning gap are unacceptably high.^^28^^\n\nReinforcing these U.N. calculations are data from the grassroots showing how access to family planning services helps couples achieve their desired family size. Surveys in Honduras, for example, show poor women (often lacking family planning services) having twice as many children as they want, while women in high socioeconomic groups are quite successful at having the number of children they desire.^^29^^\n\nShifting to smaller families brings generous economic dividends. For Bangladesh, analysts concluded that $62 spent by the government to prevent an unwanted birth saved $615 in expenditures on other social services. Investing in reproductive health and family planning leaves more fiscal resources per child for education and health care, thus accelerating the escape from poverty. For donor countries, filling the entire $6.6 billion gap needed to ensure that couples everywhere have access to the services they want and need would yield strong social returns in improved education and health care.^^30^^\n\n[[7.3 - Better Health for All]]\n\n[[7.4 - Curbing the HIV Epidemic]]\n\n[[7.5 - Reducing Farm Subsidies and Debt]]\n\n[[7.6 - A Poverty-Eradication Budget]]\n\n[[7.7 - Additional Resources]]\n\n[[7.8 - Notes]]\n\n[[8 - Restoring the Earth]]
While heart disease and cancer (largely the diseases of aging), obesity, and smoking dominate health concerns in industrial countries, in developing countries infectious diseases are the overriding health concern. Besides AIDS, the principal diseases of concern are diarrhea, respiratory illnesses, tuberculosis, malaria, and measles.\n\nMany countries can no longer afford the vaccines for childhood diseases, such as measles, and are falling behind in their vaccination programs. Lacking the funds to invest today, they pay a far higher price tomorrow. There are not many situations where just a few pennies spent per youngster can make as much difference as vaccination programs can.^^31^^\n\nAlong with the eradication of hunger, ensuring access to a safe and reliable supply of water for the estimated 1 billion people who lack it is essential to better health for all. The realistic option in many cities now may be to bypass efforts to build costly water-based sewage removal and treatment systems and to opt instead for water-free waste disposal systems that do not disperse disease pathogens. (See the description of dry compost toilets in Chapter 11.) This switch would simultaneously help alleviate water scarcity, reduce the dissemination of disease agents in water systems, and help close the nutrient cycle - another win-win-win opportunity.\n\nOne of the most impressive health gains has come from a campaign led by UNICEF to treat the symptoms of diarrheal disease with oral rehydration therapy. This remarkably simple technique, which involves drinking a mild saline solution, has been extremely effective - reducing deaths from diarrhea among children from 4.6 million in 1980 to 1.5 million in 1999. Few investments have saved so many lives at such a low cost. In //Millions Saved,// Ruth Levine describes how Egypt used oral rehydration therapy to cut infant deaths from diarrhea by 82 percent from 1982 to 1989.^^32^^\n\nSome leading sources of premature death are lifestyle-related. Cigarettes take a particularly heavy toll. The World Health Organization (WHO) estimates that 4.9 million people died in 2000 of tobacco-related illnesses, more than from any infectious disease. Today there are some 25 known diseases that are linked to tobacco use, including heart disease, stroke, respiratory illness, several forms of cancer, and male impotence. Cigarette smoke kills more people each year than all other air pollutants combined - nearly 5 million versus 3 million.^^33^^\n\nImpressive progress is being made in reducing cigarette smoking. After a century-long buildup of the tobacco habit, the world is turning away from cigarettes, led by WHO's Tobacco Free Initiative. This gained further momentum from the Framework Convention on Tobacco Control, the first international accord to deal entirely with a health issue, which was adopted unanimously in Geneva in May 2003.^^34^^\n\nIronically, the country where tobacco originated is now leading the world away from it. In the United States, the number of cigarettes smoked per person has dropped from its peak of 2,872 in 1976 to 1,374 in 2003 - a decline of 52 percent. Worldwide, where the downturn lags that of the United States by roughly a decade, usage has dropped from the historical high of 1,035 cigarettes smoked per person in 1986 to 856 in 2003, a fall of 17 percent. Media coverage of the health effects of smoking, mandatory health warnings on cigarette packs, and sharp increases in cigarette sales taxes have all contributed to the steady decline.^^35^^\n\nIndeed, smoking is on the decline in nearly all the major cigarette-smoking countries, including such strongholds as France, China, and Japan. The number of cigarettes smoked per person has dropped 22 percent in France since peaking in 1984, 5 percent in China since 1989, and 20 percent in Japan since 1991.^^36^^\n\nFollowing approval of the Framework Convention on Tobacco Control, a number of countries took strong steps in 2004 to reduce smoking. Ireland imposed a nationwide ban on smoking in workplaces, bars, and restaurants; India banned smoking in public places; Norway banned smoking in bars and restaurants; and Scotland banned smoking in public buildings. Bhutan, a Himalayan country of 1 million sandwiched between India and China, has prohibited tobacco sales entirely.^^37^^\n\nIn 2005, smoking was banned in public places in Bangladesh, in bars and restaurants in New Zealand, and in public places in Italy. In the United States, which already has stiff restrictions on smoking, the Union Pacific Corporation stopped hiring smokers in seven states as an economy measure to cut health care costs. General Mills imposes a $20-a-month surcharge on health insurance premiums for employees who smoke. Each of these measures helps the market to more accurately reflect the cost of smoking.^^38^^\n\nThe war against infectious diseases is being waged on a broad front. Perhaps the leading privately funded life-saving activity in the world today is the childhood immunization program. In an effort to fill the gap in this global program, the Bill and Melinda Gates Foundation has invested $1.5 billion through 2005 to protect children from infectious diseases.^^39^^\n\nOne of the international community's finest moments came with the eradication of smallpox, an effort led by WHO. This successful elimination of a feared disease, which required a worldwide immunization program, saves not only millions of lives but also hundreds of millions of dollars each year in smallpox vaccination programs and billions of dollars in health care expenditures. This achievement alone may justify the existence of the United Nations.^^40^^\n\nSimilarly, a WHO-led international coalition, including Rotary International, UNICEF, the U.S. Centers for Disease Control and Prevention, and Ted Turner's UN Foundation, has led a worldwide campaign to wipe out polio. Since 1988, Rotary International has contributed an extraordinary $500 million to this effort. Under this coalition-sponsored Global Polio Eradication Initiative, the number of polio cases worldwide dropped from some 350,000 per year in 1988 to just 800 in 2003.^^41^^\n\nBy mid-2003, pockets of polio remained only in Nigeria, Niger, Egypt, India, Pakistan, and Afghanistan, but then some of the Muslim-dominated states of northern Nigeria stopped vaccination because of a rumor that the vaccine would render people sterile or cause AIDS. By the end of 2004, when the misinformation was corrected, polio vaccinations were resumed in northern Nigeria. But during the interim, polio had become reestablished in several countries, apparently aided by the annual pilgrimage of Nigerian Muslims to Mecca. New infections appeared in Saudi Arabia, Yemen, C√īte d'Ivoire, Burkina Faso, the Central African Republic, Chad, Mali, Sudan, Indonesia, and Somalia.^^42^^\n\nThese countries, once free of the disease, are scrambling now to contain and eradicate the new outbreak that as of September 2005 had grown to 1,260 cases. With two recently confirmed cases in Somalia, a failed state, the fear is that the virus may spread further not only in this country where there is no government to work with, but to other countries as well, making it extraordinarily difficult to eradicate.^^43^^\n\nA 2001 WHO study analyzing the economics of health care in developing countries concluded that providing the most basic health care services, the sort that could be supplied by a village-level clinic, would yield enormous economic benefits for developing countries and for the world as a whole. The authors estimated that providing basic universal health care in developing countries will require donor grants totaling $27 billion in 2007, scaled up to $38 billion in 2015, or an average of $33 billion per year. In addition to basic services, this $33 billion includes funding for the Global Fund to Fight AIDS, Tuberculosis and Malaria and for universal childhood vaccinations.^^44^^\n\n[[7.4 - Curbing the HIV Epidemic]]\n\n[[7.5 - Reducing Farm Subsidies and Debt]]\n\n[[7.6 - A Poverty-Eradication Budget]]\n\n[[7.7 - Additional Resources]]\n\n[[7.8 - Notes]]\n\n[[8 - Restoring the Earth]]
The key to curbing the AIDS epidemic, which has so disrupted economic and social progress in Africa, is education about prevention. We know how the disease is transmitted; it is not a medical mystery. In Africa, where once there was a stigma associated with even mentioning the disease, governments are beginning to design effective prevention education programs. The first goal is to reduce quickly the number of new infections, dropping it below the number of deaths from the disease, thus shrinking the number of those who are capable of infecting others.\n\nConcentrating on the groups in a society who are most likely to spread the disease is particularly effective. In Africa, infected truck drivers who travel far from home for extended periods often engage in commercial sex, spreading HIV from one country to another. They are thus a target group for reducing infections. Sex workers are also centrally involved in the spread of the disease. In India, for example, the country's 2 million female sex workers have an average of two encounters per day, making them a key group to educate about HIV risks and the life-saving value of using a condom.^^45^^\n\nAnother target group is the military. After soldiers become infected, usually from engaging in commercial sex, they return to their home communities and spread the virus further. In Nigeria, where the adult HIV infection rate is 5 percent, President Olusegun Obasanjo requires free distribution of condoms to all military personnel. A fourth target group, intravenous drug users who share needles, figures prominently in the spread of the virus in the former Soviet republics.^^46^^\n\nAt the most fundamental level, dealing with the HIV threat requires roughly 10 billion condoms a year in the developing world and Eastern Europe. Including those needed for contraception adds another 2 billion. But of the 12 billion condoms needed, only 2.5 billion are being distributed, leaving a shortfall of 9.5 billion. At only 3¬Ę each, or $285 million, the cost of saved lives by supplying condoms is minuscule.^^47^^\n\nThe condom gap is huge, but the costs of filling it are small. In the excellent study //Condoms Count: Meeting the Need in the Era of HIV/AIDS//, Population Action International notes that "the costs of getting condoms into the hands of users - which involves improving access, logistics and distribution capacity, raising awareness, and promoting use - is many times that of the supplies themselves." If we assume that these costs are six times the price of the condoms themselves, filling this gap would still cost only $2 billion.^^48^^\n\nSadly, even though condoms are the only technology available to prevent the spread of HIV, the U.S. government is de-emphasizing their use, insisting that abstinence be given top priority. While encouraging abstinence is important, an effective campaign to curb the HIV epidemic cannot function without condoms.^^49^^\n\nOne of the few African countries to successfully lower the HIV infection rate after the epidemic became well established is Uganda. Under the strong personal leadership of President Yoweri Museveni, the share of adults infected has dropped from a peak of 13 percent in the early 1990s to 4 percent in 2003. More recently, Zambia also appears to be making progress in reducing infection rates among young people as a result of a concerted national campaign led by church groups. Senegal, which acted early and decisively to check the spread of the virus, has an infection rate among adults of less than 1 percent today. It is a model for other African countries.^^50^^\n\nThe financial resources and medical personnel currently available to treat people who are already HIV-positive are severely limited compared with the need. For example, of the 4.7 million people who exhibited symptoms of AIDS in sub-Saharan Africa in June of 2005, only 500,000 were receiving the anti-retroviral drug treatment that is widely available in industrial countries. However, this was up threefold from a year earlier. The increase is part of a worldwide effort by the World Health Organization to reach 3 million people in low- and middle-income countries by the end of 2005, known as the 3 by 5 Initiative.^^51^^\n\nThere is a growing body of evidence that the prospect of treatment encourages people to get tested for HIV. It also raises awareness and understanding of the disease and how it is transmitted. And if people know they are infected, they may try to avoid infecting others. To the extent that treatment extends life, and the average extension in the United States is about 15 years, it is not only the humanitarian thing to do, it also makes economic sense. Once society has invested in the rearing, education, and on-job training of an individual, the value of extending the working lifetime is high.^^52^^\n\nTreating those with HIV infections is costly, but ignoring the need for treatment is a strategic mistake simply because treatment strengthens prevention efforts. Africa is paying a heavy cost for its delayed response to the epidemic. It is a window on the future of other countries, such as India and China, if they do not move quickly to contain the virus that is already well established within their borders.^^53^^\n\n[[7.5 - Reducing Farm Subsidies and Debt]]\n\n[[7.6 - A Poverty-Eradication Budget]]\n\n[[7.7 - Additional Resources]]\n\n[[7.8 - Notes]]\n\n[[8 - Restoring the Earth]]
Eradicating poverty involves much more than international aid programs. For many developing countries, farm subsidies in aid-giving countries and debt relief may be even more important. A successful export-oriented farm sector - taking advantage of low-cost labor and natural endowments of land, water, and climate to boost rural incomes and to earn foreign exchange - often offers a path out of poverty. Sadly, for many developing countries this path is blocked by the self-serving farm subsidies of affluent countries. Overall, the farm subsidies in the affluent countries at $279 billion are roughly four times the development assistance flows from these governments.^^54^^\n\nThe size of the agricultural budget of the European Union (EU) is staggering, accounting for over half of its total annual budget. It also looms large internationally. As the //Financial Times// points out, the cash subsidy to a dairy cow in the EU exceeds the EU development assistance per person in sub-Saharan Africa.^^55^^\n\nWithin affluent countries, the EU-25 in 2004 accounted for $133 billion of the $279 billion spent by affluent countries on farm subsidies. The United States spent $46 billion on farm subsidies. These encourage overproduction of farm commodities, which then are sent abroad with another boost from export subsidies. The result is depressed world market prices, particularly for sugar and cotton, the two commodities where developing countries have the most to lose.^^56^^\n\nAlthough the European Union accounts for more than half of the $78 billion in development assistance from all countries, much of the economic gain from this assistance in the past was offset by the EU's annual dumping of some 6 million tons of sugar in the world market. This is one farm commodity where developing countries have a strong comparative advantage and should be permitted to capitalize on it. Fortunately, in 2005 the EU announced that it would reduce its sugar support price to farmers by 40 percent, thus discouraging the excess production that depressed the world market price when it was exported. The affluent world can no longer afford farm policies that permanently trap millions in poverty by cutting off a main avenue of escape.^^57^^\n\nHelp in raising world sugar prices may come from an unexpected quarter. Although it is too early to say for sure, rising oil prices may boost sugar prices as more and more sugarcane-based ethanol refineries are built. In effect, the price of sugar may track the price of oil upward, providing a strong economic boost for those developing-world economies where nearly all the world's sugarcane is produced.^^58^^\n\nRecent developments may also lift world cotton prices. Although the U.S. government does not have explicit export subsidies, production subsidies provided to farmers enable them to export cotton at low prices. These subsidies to just 25,000 cotton farmers exceed U.S. financial aid to all of sub-Saharan Africa's 750 million people. And since the United States is the world's leading cotton exporter, its subsidies depress prices for all cotton exporters.^^59^^\n\nU.S. cotton subsidies have faced a spirited challenge from four cotton-producing countries in Central Africa: Benin, Burkina Faso, Chad, and Mali. In addition, Brazil successfully challenged U.S. cotton subsidies within the framework of the World Trade Organization (WTO). To make its case, the Brazilian government hired a leading U.S. agricultural economist. Using U.S. Department of Agriculture data, Brazil convinced the WTO panel that U.S. cotton subsidies were depressing world prices and harming their cotton producers. In response, the panel ruled that the United States had to eliminate the subsidies.^^60^^\n\nAlong with eliminating harmful agricultural subsidies, debt forgiveness is another essential component of the broader effort to eradicate poverty. For example, with sub-Saharan Africa spending four times as much on debt servicing as it spends on health care, debt forgiveness can help boost living standards in this last major bastion of poverty.\n\nIn July of 2005, heads of the G-8 group of industrial countries, meeting in Gleneagles, Scotland, agreed to the cancellation of the multilateral debt that a number of the poorest countries owed to the World Bank, the International Monetary Fund, and the African Development Bank. This initiative, immediately affecting 18 of the poorest debt-ridden countries (14 in Africa and 4 in Latin America), offers these countries a new lease on life. Up to another 20 of the poorest countries could benefit from this initiative if they can complete the qualification. A combination of public pressure by nongovernmental groups campaigning for debt relief in recent years and strong leadership from the U.K. government were the keys to this poverty reduction breakthrough.^^62^^\n\nAlthough this was a giant step in the right direction, it eliminated only a minor share of the total debt of the poorest countries to international lending institutions. In addition to the 18 countries granted relief so far, there are at least 40 more countries with low incomes that desperately need help. The groups that are lobbying for debt relief, such as Oxfam International, believe it is inhumane to force those with incomes of scarcely a dollar per day to use part of that dollar to service debt. They pledge to keep the pressure on until all the debt of these poorest countries is cancelled.^^63 ^^\n\n[[7.6 - A Poverty-Eradication Budget]]\n\n[[7.7 - Additional Resources]]\n\n[[7.8 - Notes]]\n\n[[8 - Restoring the Earth]]
Many countries that have experienced rapid population growth for several decades are showing signs of demographic fatigue. Countries struggling with the simultaneous challenge of educating growing numbers of children, creating jobs for swelling ranks of young job seekers, and dealing with the environmental effects of population growth are stretched to the limit. When a major new threat arises - such as the HIV epidemic - governments often cannot cope.\n\nProblems routinely managed in industrial societies are becoming full-scale humanitarian crises in developing ones. The rise in deaths in many African countries marks a tragic new development in world demography. In the absence of a concerted effort by national governments and the international community to accelerate the shift to smaller families, events in many countries could spiral out of control, leading to more death and to spreading political instability and economic decline.\n\nThere is an alternative to this bleak prospect, and that is to help countries that want to slow their population growth to do so quickly. This brings with it what economists call the demographic bonus. When countries move quickly to smaller families, growth in the number of young dependents - those who need nurturing and educating - declines relative to the number of working adults. In this situation, productivity rises, savings and investment climb, and economic growth accelerates.^^64^^\n\nJapan, which cut its population growth in half between 1951 and 1958, was one of the first countries to benefit from the demographic bonus. South Korea and Taiwan followed, and more recently China, Thailand, Viet Nam, and Sri Lanka have benefited from earlier sharp reductions in birth rates. This effect lasts for only a few decades, but it is usually enough to launch a country into the modern era.^^65^^\n\nThe steps needed to eradicate poverty and accelerate the shift to smaller families are clear. They include filling several funding gaps, including those needed to reach universal primary education; to fight infectious diseases, such as AIDS, tuberculosis, and malaria; to provide reproductive health care; and to contain the HIV epidemic. Collectively, the initiatives discussed in this chapter are estimated to cost another $68 billion a year. (See Table 7-1.)^^66^^\n\nThe heaviest investments in this effort center on education and health, which are the cornerstones of both human capital development and population stabilization. Education includes both universal primary education and a global campaign to eradicate adult illiteracy. Health care includes the basic interventions involved in controlling infectious diseases, beginning with childhood vaccinations. Adopting the basic health care program outlined in the 2001 //Report of the Commission on Macroeconomics and Health// to the World Health Organization would save an estimated 8 million lives per year by 2010. These are the keys to breaking out of the poverty trap.^^67^^\n\n<<tiddler Table 7-1>>\n\nAs Jeffrey Sachs regularly reminds us, for the first time in history we have the technologies and financial resources to eradicate poverty. As noted earlier, the last 15 years have seen some impressive gains. For example, China has not only dramatically reduced the number living in poverty within its borders, but, with its trade and investment initiatives, it is helping poorer countries develop. China is investing substantial sums in Africa, investments often related to helping African countries develop their numerous mineral and energy resources, something that China needs.^^68^^\n\nHelping low-income countries break out of the demographic trap is a highly profitable investment for the world's affluent nations. Industrial-country investments in education, health, and school lunches are in a sense a humanitarian response to the plight of the world's poorest countries. But more fundamentally, they are investments that will shape the world in which our children will live.\n\n[[7.7 - Additional Resources]]\n\n[[7.8 - Notes]]\n\n[[8 - Restoring the Earth]]

The health of an economy cannot be separated from that of its natural support systems. More than half the world's people depend directly on croplands, rangelands, forests, and fisheries for their livelihoods. Many more depend on forest product industries, leather goods industries, cotton and woolen textile industries, and food processing industries for their jobs.^^1^^\n\nA strategy for eradicating poverty will not succeed if an economy's environmental support systems are collapsing. If croplands are eroding and harvests are shrinking, if water tables are falling and wells are going dry, if rangelands are turning to desert and livestock are dying, if fisheries are collapsing, if forests are shrinking, and if rising temperatures are scorching crops, a poverty-eradication program - no matter how carefully crafted and well implemented - will not succeed.\n\nIn Chapter 5, we discussed the deforestation, soil erosion, and the utter devastation of Haiti's countryside. After looking at the desperate situation in Haiti, Craig Cox, Director of the U.S.-based Soil and Water Conservation Society, wrote, "I was reminded recently that the benefits of resource conservation - at the most basic level - are still out of reach for many. Ecological and social collapses have reinforced each other in a downward spiral into poverty, environmental degradation, social injustice, disease, and violence." Unfortunately, the situation Cox describes is no longer a rarity. It describes what lies ahead for more and more countries if we do not launch an earth restoration initiative.^^2^^\n\nRestoring the earth will take an enormous international effort, one even larger and more demanding than the often-cited Marshall Plan that helped rebuild war-torn Europe and Japan. And such an initiative must be undertaken at wartime speed lest environmental deterioration translate into economic decline, just as it did for earlier civilizations that violated nature's thresholds and ignored its deadlines.\n\n[[8.1 - Protecting and Restoring Forests]]\n\n[[8.2 - Conserving and Rebuilding Soils]]\n\n[[8.3 - Meeting Nature's Water Needs]]\n\n[[8.4 - Regenerating Fisheries]]\n\n[[8.5 - Protecting Plant and Animal Diversity]]\n\n[[8.6 - The Earth Restoration Budget]]\n\n[[8.7 - Additional Resources]]\n\n[[8.8 - Notes]]\n\n[[9 - Feeding Seven Billion Well]]\n\n----\nDownload pdf version of Chapter 8\n\n 21pp. (82 Kb)
Protecting the earth's 3.9 billion hectares of remaining forests and replanting those lost are both essential for restoring the earth's health, an important foundation for the new economy. Reducing rainfall runoff and the associated flooding and soil erosion, recycling rainfall inland, and restoring aquifer recharge depend on simultaneously reducing pressure on forests and on reforestation.^^3^^\n\nThere is a vast unrealized potential in all countries to lessen the demand pressure that is shrinking the earth's forest cover. In industrial nations the greatest opportunity lies in reducing the quantity of wood used to make paper, and in developing countries it depends on reducing fuelwood use.\n\nThe rates of paper recycling in the top 10 paper-producing countries range widely, from China and Italy on the low end, recycling 27 and 31 percent of the paper they use, to Germany and South Korea on the high end, at 72 and 66 percent. The recycling rate in Germany is high because the government has consistently emphasized paper recycling to reduce the flow to landfills. If every country recycled as much of its paper as Germany does, the amount of wood pulp used to produce paper worldwide would drop by one third.^^4^^\n\nThe United States, the world's largest paper consumer, is far behind Germany but is making some progress. Twenty years ago, roughly one fourth of the paper used in the United States was recycled. By 2003, the figure had reached 48 percent.^^5^^\n\nThe use of paper, perhaps more than any other single product, reflects the throwaway mentality that evolved during the last century. There is an enormous possibility for reducing paper use simply by replacing facial tissues, paper napkins, disposable diapers, and paper shopping bags with reusable cloth alternatives.\n\nThe largest single demand on trees - the need for fuel - accounts for just over half of all wood removed from forests. Some international aid agencies, including the U.S. Agency for International Development (AID), have begun to sponsor fuelwood efficiency projects. One of AID's more promising national projects is the distribution of 780,000 new, highly efficient wood cookstoves in Kenya. Investing public resources in replacing outmoded inefficient cookstoves can earn handsome dividends in forest protection and regeneration, including the restoration of forest services.^^6^^\n\nOver the longer term, developing alternative cooking fuels is the key to reducing forest pressure in developing countries. As the world shifts from a fossil-fuel-reliant economy to one based on wind, solar, and geothermal energy, it will be much easier for developing countries without fossil fuels to develop indigenous sources of renewable energy. Replacing firewood with solar thermal cookers, with electric hotplates fed by wind-generated electricity, or with some other energy source will lighten the load on forests.\n\nKenya is also the site of a solar cooker project sponsored by Solar Cookers International. These inexpensive cookers, made from cardboard and aluminum foil and costing $10 each, cook slowly, much like a crockpot. Requiring three hours of sunshine to cook a complete meal, they can greatly reduce firewood use at little cost. They can also be used to pasteurize water, thus saving lives.^^7^^\n\nEarlier definitions of sustainable forestry focused only on the sustained production of forest products, but they now include sustaining forest services such as flood control. Despite the high value to society of intact forests, only about 290 million hectares of global forest area are legally protected from logging. An additional 1.4 billion hectares are economically unavailable for harvesting because of geographic inaccessibility or low-value wood. Of the remaining area available for exploitation, 665 million hectares are undisturbed by humans and nearly 900 million hectares are semi-natural and not in plantations.^^8^^\n\nForests that are protected by national decree are often safeguarded not so much to preserve the long-term wood supply capacity as to ensure that the forest can continue to provide services. Countries that provide legal protection for forests often do so after they have suffered the consequences of extensive deforestation. The Philippines, for example, has banned logging in all remaining old-growth and virgin forests largely because the country has become so vulnerable to flooding, erosion, and landslides. The country was once covered by rich stands of tropical hardwood forests, but after years of massive clearcutting, it lost both the forest's products and its services and became a net importer of forest products.^^9^^\n\nReed Funk, professor of plant biology at Rutgers University, believes the vast areas of deforested land can be used to grow trillions of genetically improved trees for food, mostly nuts, and for fuel. Funk sees nuts used to supplement meat as a source of high-quality protein in developing-country diets. He also sees trees grown on this deforested land, much of it now wasteland, being used for conversion into ethanol for automotive fuel.^^10^^\n\nAlthough nongovernmental organizations (NGOs) have worked for years to protect forests from clearcutting, the World Bank has only recently begun to systematically consider sustainable forestry. In 1998, the Bank joined forces with the World Wide Fund for Nature to form the Alliance for Forest Conservation and Sustainable Use; by 2005 they had helped designate 50 million hectares of new forest protected areas and certify 22 million hectares of forest. In mid-2005, the Alliance announced a goal of reducing global deforestation rates to zero by 2020.^^11^^\n\nThere are several forest product certification programs that link environmentally conscious consumers with sustainable management of the forest where the product originates. Some programs are national while others are international; some originate with importing countries and others with exporters.\n\nThe most rigorous international program, one that is certified by a group of NGOs, is the Forest Stewardship Council (FSC). Some 57 million hectares of forests in 65 countries are certified by FSC-accredited bodies as responsibly managed. Among the leaders in certified forest area are Sweden, with 10 million hectares; Poland, with 6 million hectares; the United States, with nearly 5 million hectares; and Brazil and South Africa, with 3 million and 2 million hectares respectively.\n\nForest plantations can reduce pressures on the earth's remaining forests as long as they do not replace old-growth forest. As of 2000, the world had 187 million hectares in forest plantations, an area less than 5 percent of the total 3.9 billion hectares in forest and equal to nearly one fourth of the 700 million hectares planted in grain. Tree plantations produce mostly wood for paper mills or for wood reconstitution mills. Increasingly, reconstituted wood is substituting for natural wood in the world lumber market as industry adapts to a shrinking supply of large logs from natural forests.^^13^^\n\nProduction of roundwood on plantations is estimated at 414 million cubic meters per year, accounting for 12 percent of world wood production. This means that the lion's share, some 88 percent of the world timber harvest, comes from natural forest stands.^^14^^\n\nFive countries account for two thirds of tree plantations. China, which has little original forest remaining, is the largest, with Russia and the United States following. India and Japan are fourth and fifth. Brazil is further back, but is expanding fast. As tree farming expands, it is shifting geographically to the moist tropics. In contrast to grain yields, which tend to rise with distance from the equator and the longer summer growing days, tree plantation yields rise with proximity to the equator and year-round growing conditions. ^^15^^\n\nIn eastern Canada, the average hectare of forest plantation produces 4 cubic meters per year. In the southeastern United States, where U.S. plantations are concentrated, the yield is 10 cubic meters. But in Indonesia, it is 25 cubic meters, and in Brazil, newer plantations may be close to 30 cubic meters. While corn yields in the United States are nearly triple those in Brazil, timber yields are the reverse, favoring Brazil by nearly 3 to 1. To satisfy a given demand for wood, Brazil requires only one third as much land as the United States, which helps explain why growth in pulp capacity is now concentrated in equatorial regions.^^16^^\n\nProjections of future growth show that plantations are constrained by land scarcity. They can sometimes be profitably established on already deforested, often degraded, land, but they are more likely to come at the expense of existing forests. There is also competition with agriculture, since land that is suitable for crops is also good for growing trees. Water scarcity is yet another constraint. Fast-growing plantations require abundant moisture.\n\nNonetheless, the U.N. Food and Agriculture Organization (FAO) projects that as plantation area expands and yields rise, the harvest could more than double during the next three decades. It is entirely conceivable that plantations could one day satisfy most of the world's demand for industrial wood, thus helping to protect the world's remaining forests.^^17^^\n\nHistorically, some highly erodible agricultural land in industrial countries has been reforested by natural regrowth. For example, New England, a geographically rugged region of the United States, was reforested beginning a century or so ago. Settled early by Europeans, this region was suffering from cropland productivity losses because soils were thin and the land was rocky, sloping, and vulnerable to erosion. As highly productive farmland opened up in the Midwest and the Great Plains during the nineteenth century, pressures on New England farmland lessened, permitting cropped land to return to forest. New England's forest cover has increased from a low of roughly one third two centuries ago to perhaps three fourths today, slowly regaining its original health and diversity.\n\nA somewhat similar situation exists now in parts of the former Soviet Union and in several East European countries. As central planning was replaced by market-based agriculture in the early 1990s, farmers on marginal land were forced to seek their livelihoods elsewhere. Precise figures are difficult to come by, but millions of hectares of farmland are now returning to forest.^^19^^\n\nSouth Korea is in many ways a reforestation model for the rest of the world. When the Korean War ended, half a century ago, the mountainous country was largely deforested. Beginning around 1960, under the dedicated leadership of President Park Chung Hee, the South Korean government launched a national reforestation effort. Relying on the creation of village cooperatives, hundreds of thousands of people were mobilized to dig trenches and to create terraces for supporting trees on barren mountains. South Korea not only reclaimed denuded areas, it also supported the effort with the establishment of fuelwood forests. Se-Kyung Chong, researcher at the Korea Forest Research Institute, writes, "The result was a seemingly miraculous rebirth of forests from barren land."^^20^^\n\nToday forests cover 65 percent of the country, an area of roughly 8 million hectares. While driving across South Korea in November 2000, it was gratifying for me to see the luxuriant stand of trees on mountains that a generation ago were bare. We can reforest the earth!^^21^^\n\nIn Turkey, a mountainous country largely deforested over millennia, a leading environmental group, TEMA (T√úrkiye Erozyona M√úcadele, Agaclandirma), has made reforestation its principal activity. Founded by two prominent Turkish businessmen, Hayrettin Karuca and Nihat Gokyigit, TEMA launched in 1998 a 10-billion-acorn campaign to restore tree cover and reduce runoff and soil erosion. During the years since, 850 million oak acorns have been planted. The program is also raising national awareness of the services that forests provide.^^22^^\n\nChina is engaging in its own reforestation effort. In addition to planting trees in the recently deforested upper reaches of the Yangtze River basin to control flooding, China is planting a belt of trees to protect land from the expanding Gobi Desert. This green wall, a modern version of the Great Wall, is projected to reach some 4,480 kilometers (2,800 miles) in length, stretching from outer Beijing through Inner Mongolia. An ambitious, long-term plan, it is expected to take 70 years to complete and to cost up to $8 billion.^^23^^\n\nShifting subsidies from building logging roads to planting trees would help protect forest cover worldwide. The World Bank has the administrative capacity to lead an international program that would emulate South Korea's success in blanketing mountains and hills with trees.\n\nIn addition, FAO and the bilateral aid agencies can work with individual farmers in national agroforestry programs to integrate trees wherever possible into agricultural operations. Well-chosen, well-placed trees provide shade, serve as windbreaks to check soil erosion, and can fix nitrogen, reducing the need for fertilizer.\n\nReducing wood use by developing more-efficient wood stoves and alternative means of cooking, systematically recycling paper, and banning the use of throwaway paper products all lighten pressure on the earth's forests. A global reforestation effort cannot succeed unless it is accompanied by the stabilization of population. With such an integrated plan, coordinated country by country, the earth's forests can be restored.\n\n[[8.2 - Conserving and Rebuilding Soils]]\n\n[[8.3 - Meeting Nature's Water Needs]]\n\n[[8.4 - Regenerating Fisheries]]\n\n[[8.5 - Protecting Plant and Animal Diversity]]\n\n[[8.6 - The Earth Restoration Budget]]\n\n[[8.7 - Additional Resources]]\n\n[[8.8 - Notes]]\n\n[[9 - Feeding Seven Billion Well]]
In reviewing the literature on soil erosion, references to the "loss of protective vegetation" occur again and again. Over the last half-century, we have removed so much of that protective cover by clearcutting, overgrazing, and overplowing that we are fast losing soil accumulated over long stretches of geological time. Eliminating these excesses and the resultant decline in the earth's biological productivity depends on a worldwide effort to restore the earth's vegetative cover, an effort that is now under way in some countries.\n\nThe 1930s Dust Bowl that threatened to turn the U.S. Great Plains into a vast desert was a traumatic experience that led to revolutionary changes in American agricultural practices, including the planting of tree shelterbelts - rows of trees planted beside fields to slow wind and thus reduce wind erosion - and strip-cropping, the planting of wheat on alternate strips with fallowed land each year. Strip cropping permits soil moisture to accumulate on the fallowed strips, while the alternating planted strips reduce wind speed and hence erosion on the idled land.^^24^^\n\nIn 1985, the U.S. Congress, with strong support from the environmental community, created the Conservation Reserve Program (CRP) to reduce soil erosion and control overproduction of basic commodities. By 1990 there were some 14 million hectares (35 million acres) of highly erodible land in permanent vegetative cover under 10-year contracts. Under this program, farmers were paid to plant fragile cropland to grass or trees. The retirement of 14 million hectares under the CRP, together with the use of conservation practices on 37 percent of all cropland, reduced U.S. soil erosion from 3.1 billion tons to 1.9 billion tons during the 15 years from 1982 to 1997. The U.S. approach to controlling soil erosion by both converting highly erodible cropland back to grassland or trees and adopting soil conservation practices offers a model for the rest of the world.^^25^^\n\nThe conversion of cropland to nonfarm uses is often beyond the control of farmers, but the losses of soil and eroded land from severe erosion are not. Lowering soil losses caused by wind and water erosion below the gains in new soil formed by natural processes will take an enormous worldwide effort. Preserving the biological productivity of highly erodible cropland depends on planting it in grass or trees before it becomes wasteland. The first step in halting the decline in inherent land fertility is to pull back from this fast-deteriorating margin.^^26^^\n\nTerracing, a time-tested method for dealing with water erosion, is common in rice paddies throughout the mountainous regions of Asia. On less steeply sloping land, contour strip farming, as found in the U.S. Midwest, works well.^^27^^\n\nAnother tool in the soil conservation toolkit - and a relatively new one - is conservation tillage, which includes both no-till and minimum tillage. In addition to reducing both wind and water erosion, this practice helps retain water, raises soil carbon content, and reduces the energy needed for crop cultivation.\n\nInstead of the traditional cultural practices of plowing land, discing or harrowing it to prepare the seedbed, and then using a mechanical cultivator to control weeds in row crops, farmers simply drill seeds directly through crop residues into undisturbed soil, controlling weeds with herbicides. The only soil disturbance is the narrow slit in the soil surface where the seeds are inserted, leaving the remainder of the soil undisturbed, covered by crop residues and thus resistant to both water and wind erosion.^^28^^\n\nIn the United States, where farmers during the 1990s were required to implement a soil conservation plan on erodible cropland to be eligible for commodity price supports, the no-till area went from 7 million hectares in 1990 to 25 million hectares in 2004. Now widely used in the production of corn and soybeans in the United States, no-till has spread rapidly in the western hemisphere, covering 24 million hectares in 2004 in Brazil, 18 million hectares in Argentina, and 13 million in Canada. Australia, with 9 million hectares, rounds out the five leading no-till countries.^^29^^\n\nOnce farmers master the practice of no-till, its use can spread rapidly, particularly if governments provide economic incentives or require farm soil conservation plans for farmers to be eligible for crop subsidies. Recent FAO reports describe the early growth in no-till farming over the last few years in Europe, Africa, and Asia.^^30^^\n\nAlgeria, trying to halt the northward advance of the Sahara Desert, announced in December 2000 that it is concentrating its orchards and vineyards in the southern part of the country, hoping that these perennial plantings will halt the desertification of its cropland. In July 2005, the Moroccan government, responding to severe drought, announced that it was allocating $778 million to cancel farmers' debts and to convert cereal-planted areas into less vulnerable olive and fruit orchards."^^31^^\n\nThere are similar concerns about the expanding Sahara on the southern edge of the desert as well. President Olusegun Obasanjo of Nigeria has proposed planting a Great Green Wall of trees, a band five kilometers wide stretching 7,000 kilometers across Africa, in an effort to halt the desert's advance. Senegal, which is on the western end of this proposed wall and is losing 50,000 hectares of productive land each year, strongly supports the idea. No one knows how long this project would take, but Senegalese environment minister Modou Fada Diagne observes, "Poverty and desertification create a vicious cycle. ... Instead of waiting for the desert to come to us, we need to attack it."^^32^^\n\nAs noted earlier, China also is trying to halt the advance of deserts with its Great Green Wall. In addition, it is paying farmers in the threatened provinces to plant their cropland in trees. The goal is to plant trees on 10 million hectares of grainland, easily one tenth of China's current grainland area.^^33^^\n\nIn Inner Mongolia (Nei Monggol), efforts to halt the advancing desert and to reclaim the land for productive uses rely on planting desert shrubs to stabilize the sand dunes. And in many situations, sheep and goats have been banned entirely. In Helin County, south of the provincial capital of Hohhot, the planting of desert shrubs on abandoned cropland has now stabilized the soil on the county's first 7,000-hectare reclamation plot. Based on this success, the reclamation effort is being expanded.^^34^^\n\nThe Helin County strategy centers on replacing the large number of sheep and goats with dairy cattle, increasing the number of dairy animals from 30,000 in 2002 to 150,000 by 2007. The cattle are kept in enclosed areas, feeding on cornstalks, wheat straw, and the harvest from a drought-tolerant forage crop resembling alfalfa, which is grown on reclaimed land. Local officials estimate that this program will double incomes within the county during this decade.^^35^^\n\nTo relieve pressure on the country's rangelands, Beijing is asking herders to reduce their flocks of sheep and goats by 40 percent. But in communities where wealth is measured in livestock numbers and where most families are living in poverty, such cuts are not easy or, indeed, likely, unless alternative livelihoods are offered pastoralists along the lines proposed in Helin County.\n\nThe only viable way to eliminate overgrazing on the two fifths of the earth's land surface classified as rangelands is to reduce the size of flocks and herds. Not only do the excessive numbers of cattle, and particularly sheep and goats, remove the vegetation, but their hoofs pulverize the protective crust of soil that is formed by rainfall and that checks wind erosion. In some situations, the only viable option is to keep the animals in enclosures, bringing the forage to them. India, which has successfully adopted this practice for its thriving dairy industry, is the model for other countries.^^37^^\n\nProtecting the earth's remaining vegetation also warrants a ban on the clearcutting of forests in favor of selective harvesting, simply because with each clearcut there are heavy soil losses until the forest regenerates. Thus with each subsequent cutting, productivity declines further. Restoring the earth's tree and grass cover protects soil from erosion, reduces flooding, and sequesters carbon. It is one way we can restore the earth so that it can support our children and grandchildren.\n\n[[8.3 - Meeting Nature's Water Needs]]\n\n[[8.4 - Regenerating Fisheries]]\n\n[[8.5 - Protecting Plant and Animal Diversity]]\n\n[[8.6 - The Earth Restoration Budget]]\n\n[[8.7 - Additional Resources]]\n\n[[8.8 - Notes]]\n\n[[9 - Feeding Seven Billion Well]]
There are many reasons for balancing water demand and supply. Failure to do so means that water tables will continue to fall, more rivers will run dry, and more lakes will disappear. If water tables are falling while energy prices are rising, irrigation water costs can rise to where farmers can no longer afford to irrigate. (Ways to raise irrigation efficiency are discussed in Chapter 9. Chapter 11 describes ways to reduce urban water waste.)\n\nIn //Rivers for Life: Managing Water for People and Nature//, Sandra Postel and Brian Richter cite South Africa's 1998 National Water Act as a model for other countries. The act focuses on two broad needs. The first is satisfying basic water needs of everyone for drinking, cooking, sanitation, and other essential purposes, which the legislation describes as a nonnegotiable allocation. The second is the water needed to support river ecosystem functions "in order to conserve biodiversity and secure the valuable ecosystem services they provide to society."^^38^^\n\nEstablishing minimal river flows so as to satisfy the specific needs of downstream aquatic ecosystems such as floodplains, river deltas, and wetlands is not necessarily easy. For example, at times a strong flow is needed to meet the freshwater needs of an estuary. At other times, the needs of spawning fish may determine the ecological water needs.\n\nA World Conservation Union-IUCN study in Australia notes that the Mowamba aqueduct has been permanently closed after 100 years of use in order to raise the flow of the Snowy River. This initial action, which raises the river flow from 3 percent of the natural level to 6 percent, is the first in a series of steps to bring the river flow back to 28 percent of the natural level and thus to restore its natural functions. In Australia's Murray-Darling basin, the enhanced flow of a river with releases from a storage facility in the basin helped to restore the natural wildlife population. The IUCN report noted, "the great egret bred for the first time since 1979, nine species of frog bred, as did native fish." ^^39^^\n\nPerhaps the best known and largest example of returning water to restore and support marine habitats occurred in California when the U.S. Congress passed legislation in 1992 that was designed to restore the overall health of the fish and wildlife habitat, including salmon runs, of the Sacramento-San Joaquin river system. Initially, as Sandra Postel reports in //Pillar of Sand,// Congress authorized the use of 800,000 acre-feet, nearly 1 billion cubic meters, or about 10 percent of the Central Valley Project's yearly water supply, for this purpose. Farmers who lost part of their irrigation water challenged the law.^^40^^\n\nAfter several years of legal challenges and negotiations involving environmental groups, farmers, state government officials, and others, agreement was reached on an arrangement more or less consistent with the original congressional intent. The increased flow of the two rivers, which merge before emptying into San Francisco Bay, also helped protect the Bay's rich aquatic ecosystem, which is home to some 120 species of fish.^^41^^\n\nVariations of these efforts to restore river flows to supply natural systems with the water they need are now commonplace. In the United States, literally hundreds of smaller dams are being demolished in an effort to restore river flows and natural systems, including spawning runs.^^42^^\n\nIn situations where growing water demand is exceeding the supply in more and more river basins, the challenge is to establish guidelines by which the various needs for water are met, recognizing that few will be fully met. Success hinges on having the institutions and a process by which water can be allocated among competing uses in a way that maximizes the contribution to society as a whole rather than to a small number of influential stakeholders at the expense of others.\n\n[[8.4 - Regenerating Fisheries]]\n\n[[8.5 - Protecting Plant and Animal Diversity]]\n\n[[8.6 - The Earth Restoration Budget]]\n\n[[8.7 - Additional Resources]]\n\n[[8.8 - Notes]]\n\n[[9 - Feeding Seven Billion Well]]
For decades governments tried to save specific fisheries by restricting the catch of individual species. Sometimes this worked; sometimes it failed and fisheries collapsed. In recent years, support for another approach - the creation of marine reserves or marine parks - has been gaining momentum. A network of marine reserves is defined as "a set of marine reserves within a biogeographic region, connected by larval dispersal and juvenile or adult migration." Reserves serve as natural hatcheries, helping to repopulate the surrounding area.^^43^^\n\nIn 2002, at the World Summit on Sustainable Development in Johannesburg, coastal nations pledged to create national networks of marine parks, which together could constitute a global network of such parks. At the World Parks Congress in Durban in 2003, delegates recommended protecting 20-30 percent of each marine habitat from fishing. This would be up from 0.5 percent of the oceans that are currently included in marine reserves of widely varying size. It compares with the 12 percent of the earth's land area that is in parks.^^44^^\n\nA U.K. team of scientists led by Dr. Andrew Balmford of the Conservation Biology Group at Cambridge University analyzed the costs of operating marine reserves on a large scale based on data from 83 relatively small, well-managed reserves. They concluded that managing reserves that covered 30 percent of the world's oceans would cost $12-14 billion a year. This did not take into account the likely additional income from recovering fisheries, which would reduce the actual cost.^^45^^\n\nAt stake in the creation of a global network of marine reserves is the protection and possible increase of an annual oceanic fish catch worth $70-80 billion. Balmford said, "Our study suggests that we could afford to conserve the seas and their resources in perpetuity, and for less than we are now spending on subsidies to exploit them unsustainably."^^46^^\n\nCoauthor of the U.K. study Callum Roberts, of the University of York, noted: "We have barely even begun the task of creating marine parks. Here in Britain a paltry one-fiftieth of one percent of our seas is encompassed by marine nature reserves and only one-fiftieth of their combined area is closed to fishing." Yet the seas are being devastated by unsustainable fishing, pollution, and mineral exploitation. The creation of the global network of marine reserves - "Serengetis of the seas," as some have dubbed them - would create more than 1 million jobs. Roberts went on to say, "If you put areas off limits to fishing, there is no more effective way of allowing things to live longer, grow larger, and produce more offspring."^^47^^\n\nJane Lubchenco, former President of the American Association for the Advancement of Science, strongly underlined Roberts' point when releasing a statement signed by 161 leading marine scientists calling for urgent action to create the global network of marine reserves. Drawing on the research of scores of marine parks, she said: "All around the world there are different experiences, but the basic message is the same: marine reserves work, and they work fast. It is no longer a question of //whether// to set aside fully protected areas in the ocean, but //where// to establish them."^^48^^\n\nThe signatories noted how quickly sea life improves once the reserves are established. A case study of a snapper fishery off the coast of New England showed that fishers, though they violently opposed the establishment of the reserve at first, now champion it because they have seen the local population of snapper increase 40-fold. In a study in the Gulf of Maine, all fishing methods that put ground fish at risk were banned within three marine reserves totaling 17,000 square kilometers. Unexpectedly, scallops flourished in this undisturbed environment, and their populations increased by 9-14 times within five years. This population buildup within the reserves also greatly increased the scallop population outside the reserves. The group of 161 scientists noted that within a year or two of establishing a marine reserve, population densities increased 91 percent, average fish size went up 31 percent, and species diversity rose 20 percent.^^49^^\n\nWhile the creation of marine reserves is clearly the overriding priority in the long-standing effort to protect marine ecosystems, other measures are also required. One is to reduce the nutrient flows from fertilizer runoff and untreated sewage. These increased nutrient flows cause huge algal blooms that then die off and in the process of decomposition absorb all the free oxygen in the water, leading to the death of local sea life. Today there are some 146 dead zones, either seasonal or chronic, scattered in the world's oceans from the Gulf of Mexico to the Baltic Sea to the east coast of China.^^50^^\n\nThe Gulf of Mexico dead zone near the mouth of the Mississippi River is one of the best known. This New Jersey-size area substantially reduces the marine diversity and yield of this historically productive body of water. Better control of nutrient runoff can be achieved through the adoption of such farming practices as minimum tillage and no-till, through the precise application of fertilizer to meet crop needs, and through planting buffer and filter strips along the Mississippi River and its tributaries.^^51^^\n\nIn the end, there is a need for governments to eliminate fishery subsidies. There are now so many fishing trawlers that their catch potential is nearly double any yield the oceans can sustain. Managing a network of marine reserves governing 30 percent of the oceans would cost only $12-14 billion - substantially less than the $15-30 billion that governments dole out today as subsidies to fishers.^^52^^\n\n[[8.5 - Protecting Plant and Animal Diversity]]\n\n[[8.6 - The Earth Restoration Budget]]\n\n[[8.7 - Additional Resources]]\n\n[[8.8 - Notes]]\n\n[[9 - Feeding Seven Billion Well]]
The two steps essential to protecting the earth's extraordinary biological diversity are the stabilization of population and climate. If the world's population increases to 9 billion by mid-century, countless more plant and animal species may simply be crowded off the planet. If carbon dioxide levels and temperatures continue to rise, every ecosystem will change.\n\nAiming for the low U.N. population trajectory, which has world population peaking at 7.8 billion in 2041 and then gradually declining, is the most effective option for protecting earth's rich diversity of life. As it becomes more difficult to raise land productivity, continuing population growth will force farmers to clear ever more tropical forests in the Amazon and Congo basins and the outer islands of Indonesia.^^53^^\n\nWater management at a time of growing water shortages is a key in protecting marine species. When rivers are drained dry to satisfy growing human needs for irrigation and for urban water, marine species cannot survive.\n\nPerhaps the best known and most popular way of trying to protect plant and animal species is to create reserves. Millions of square kilometers have been set aside as parks. Indeed, some 12 percent of the earth's land area is now included in parks and nature preserves. With more resources, some of these parks in developing countries that now exist only on paper could become a reality.\n\nSome 15 years ago, Norman Myers and other scientists conceived the idea of biodiversity "hotspots" - areas that were especially rich biologically and thus deserving of special protection. This helped the World Wide Fund for Nature, Conservation International, The Nature Conservancy, and many other groups and governments to concentrate their preservation efforts. The 34 hotspots identified once covered nearly 16 percent of the earth's land surface, but largely because of habitat destruction they now cover less than 3 percent. Concentrating preservation efforts in these biologically rich regions was a step in the right direction.^^55^^\n\nSome 30 years ago, the United States created the Endangered Species Act. This legislation prohibited any activities, such as clearing new land for agriculture and housing developments or draining wetlands, that would threaten an endangered species. There are numerous species in the United States, such as the bald eagle, that might now be extinct had it not been for this one piece of legislation.^^56^^\n\nAs a species humans have an enormous influence on the habitability of the planet for the millions of other species with which we share it. This influence brings with it an unprecedented responsibility.\n\n[[8.6 - The Earth Restoration Budget]]\n\n[[8.7 - Additional Resources]]\n\n[[8.8 - Notes]]\n\n[[9 - Feeding Seven Billion Well]]
Although we lack detailed data in some cases, we can roughly estimate how much it will cost to reforest the earth, protect the earth's topsoil, restore rangelands and fisheries, stabilize water tables, and protect biological diversity. Where data and information are lacking, we fill in with assumptions. The goal is not to have a set of precise numbers, but a set of reasonable estimates for an earth restoration budget. (See Table 8-1.)^^57^^\n\nCalculating the cost of reforestation is complicated by the many approaches used. As noted, the big success story is South Korea, which over the last four decades has reforested its once denuded mountains and hills using locally mobilized labor. Other countries, including China, have tried extensive reforestation but mostly under more arid conditions and with much less success. Turkey has an ambitious NGO-led grassroots reforestation program, relying heavily on volunteer labor. So, too, does Kenya, where women's groups led by Nobel Peace Prize-winner Wangari Maathai have planted 30 million trees.^^58^^\n\nIn calculating reforestation costs, the focus is on developing countries since forested area is already expanding in the northern hemisphere's industrial countries. Meeting the growing fuelwood demand in these countries will require roughly an estimated 55 million additional hectares of forested area. Anchoring soils and restoring hydrological stability would require roughly another 100 million hectares located in thousands of watersheds in developing countries. Recognizing some overlap between these two, we will reduce the 155 million total to 150 million hectares. Beyond this, an additional 30 million hectares will be needed to produce lumber, paper, and other forest products.^^59^^\n\n<<tiddler Table 8-1>>\n\nOnly a small share of this tree planting will likely come from plantations. Much of the planting will be on the outskirts of villages, along field boundaries, along roads, on small plots of marginal land, and on denuded hillsides. The labor for this will be local; some will be paid labor, some volunteer. Nearly all will be off-season labor. In China, farmers now planting trees where they once planted grain are compensated with grain from state-held stocks over a five-year period while the trees are becoming established.^^60^^\n\nReforestation is something of an uphill battle partly because the deforested land is often severely eroded and depleted of nutrients. Even the most dedicated nurturing does not guarantee high survival rates under marginal conditions.\n\nIf seedlings cost $40 per thousand, as the World Bank estimates, and if the typical planting rate is roughly 2,000 per hectare, then seedlings cost $80 per hectare. Labor costs for planting trees are high, but since much of the labor for planting these trees would consist of locally mobilized volunteers, we are assuming a total of $400 per hectare, including both seedlings and labor. With a total of 150 million hectares to be planted over the next decade, this will come to roughly 15 million hectares per year at $400 each for a total annual expenditure of $6 billion.^^61^^\n\nConserving the earth's topsoil by reducing erosion to the rate of new soil formation or below involves two principal steps. One is to retire the highly erodible land that cannot sustain cultivation - the estimated one tenth of the world's cropland that accounts for perhaps half of all erosion. For the United States, that has meant retiring 14 million hectares (nearly 35 million acres). The cost of keeping this land out of production is close to $50 per acre or $125 per hectare. In total, annual payments to farmers to plant this land in grass or trees under 10-year contracts approached $2 billion.^^62^^\n\nThe second initiative consists of adopting conservation practices on the remaining land that is subject to excessive erosion - that is, erosion that exceeds the natural rate of new soil formation. The initiative includes incentives to encourage farmers to adopt conservation practices such as contour farming, strip cropping, and, increasingly, minimum-till or no-till farming. These expenditures in the United States total roughly $1 billion per year.^^63^^\n\nIn expanding these estimates to cover the world, it is assumed that roughly 10 percent of the world's cropland is highly erodible and should be planted to grass or trees before the topsoil is lost and it becomes barren land. In both the United States and China, the two leading food-producing countries, which account for a third of the world grain harvest, the official goal is to retire one tenth of all cropland. In Europe, it likely would be somewhat less than 10 percent, but in Africa and the Andean countries it could be substantially higher than that. For the world as a whole, converting 10 percent of cropland that is highly erodible to grass or trees seems a reasonable goal. Since this costs roughly $2 billion in the United States, which represents one eighth of the world cropland area, the total for the world would be roughly $16 billion annually.^^64^^\n\nAssuming that the need for erosion control practices for the rest of the world is similar to that in the United States, we again multiply the U.S. expenditure by eight to get a total of $8 billion for the world as a whole. The two components together - $16 billion for retiring highly erodible land and $8 billion for adopting conservation practices - give an annual total for the world of $24 billion.^^65^^\n\nFor cost data on rangeland protection and restoration, we turn to the United Nations Plan of Action to Combat Desertification. This plan, which focuses on the world's dryland regions, containing nearly 90 percent of all rangeland, estimates that it would cost roughly $183 billion over a 20-year restoration period - or $9 billion per year. The key restoration measures include improved rangeland management, financial incentives to eliminate overstocking, and revegetation with appropriate rest periods, when grazing would be banned.^^66^^\n\nThis is a costly undertaking, but every dollar invested in rangeland restoration yields a return of $2.50 in income from the increased productivity of the rangeland ecosystem. From a societal point of view, countries with large pastoral populations, where the rangeland deterioration is concentrated, are invariably among the world's poorest. The alternative to action - ignoring the deterioration - brings not only a loss of land productivity, but ultimately millions of refugees, some migrating to nearby cities and others moving to other countries.^^67^^\n\nThe restoration of oceanic fisheries centers primarily on the establishment of a worldwide network of marine reserves, which would cover roughly 30 percent of the ocean's surface. For this exercise we use the detailed calculations by the U.K. team cited earlier in the chapter. Their estimated range of expenditures centers on $13 billion per year.^^68^^\n\nFor wildlife protection, the bill is somewhat higher. The World Parks Congress estimates that the annual shortfall in funding needed to manage and to protect existing areas designated as parks comes to roughly $25 billion a year. Additional areas needed, including those encompassing the biologically diverse hotspots not yet included in designated parks, would cost perhaps another $6 billion a year, yielding a total of $31 billion.^^69^^\n\nThere is one activity, stabilizing water tables, where we do not have an estimate, only a guess. The key to stabilizing water tables is raising water productivity, and for this we have the experience gained beginning a half-century ago when the world started to systematically raise land productivity. The elements needed in a comparable water model are research to develop more water-efficient irrigation practices and technologies, the dissemination of these research findings to farmers, and economic incentives that encourage farmers to adopt and use these improved irrigation practices and technologies.\n\nThe area for raising irrigation water productivity is much smaller than that for land productivity. Indeed, only about one fifth of the world's cropland is irrigated. In disseminating the results of irrigation research, there are actually two options today. One is to work through agricultural extension services, which were created to funnel new information to farmers on a broad range of issues, including irrigation. Another possibility is to work through the water users associations that have been formed in many countries. The advantage of the latter is that they are focused exclusively on water.^^70^^\n\nEffectively managing underground water supplies requires knowledge of the amount of water being pumped and aquifer recharge rates. In most countries this information is simply not available. Finding out how much is pumped may mean installing meters on irrigation well pumps, much as has been done in Jordan and Mexico.^^71^^\n\nIn some countries, the capital needed to fund a program to raise water productivity can come from cancelled subsidies that now often encourage the wasteful use of irrigation water. Sometimes these are power subsidies, as they are in India; other times they are subsidies that provide water at prices well below costs, as happens in the United States. In terms of additional resources needed worldwide, including the economic incentives for farmers to use more water-efficient practices and technologies, we assume it will take additional expenditures of $10 billion.^^72^^\n\nAltogether, restoring the earth will require additional expenditures of $93 billion per year. Many will ask, Can the world afford this? But the only appropriate question is, Can the world afford to not make these investments?\n\n[[8.7 - Additional Resources]]\n\n[[8.8 - Notes]]\n\n[[9 - Feeding Seven Billion Well]]

In April 2005, the World Food Programme and the Chinese government jointly announced that food aid shipments to China would stop after the end of the year. For a country where hundreds of millions of people were chronically hungry a generation ago, this was a landmark achievement. China's success in largely eradicating hunger can be traced to the wholesale reduction in poverty associated with the eightfold expansion in its economy since the economic reforms of 1978 and the 50-percent jump in its grain harvest between 1977 and 1986.^^1^^\n\nWhile hunger has been disappearing in China, it has been spreading in sub-Saharan Africa and parts of the Indian subcontinent. As a result, the number of people who are hungry has increased from a recent historical low of 820 million in 2000 to 852 million in 2002.^^2^^\n\nOne key to the threefold expansion in the world grain harvest since 1950 was the rapid adoption in developing countries of high-yielding wheats and rices developed in Japan and hybrid corn from the United States. The spread of these highly productive seeds, combined with a tripling of irrigated area and a ninefold increase in world fertilizer use, tripled the world grain harvest. Growth in irrigation and fertilizer use essentially removed soil moisture and nutrient constraints on crop yields in much of the world.^^3^^\n\nBut now the world's farmers face enormous additional demand for farm products from the projected addition of some 70 million people a year, the desire by some 5 billion people to consume more livestock products, and the potential of millions of motorists turning to farm-produced fuel crops to supplement tightening supplies of gasoline and diesel fuel. On the supply side, farmers are faced with shrinking supplies of irrigation water, rising temperatures, the loss of cropland to nonfarm uses, rising fuel costs, and a dwindling backlog of yield-raising technologies. For those who like to be challenged, this is a good time to be a farmer or an agronomist.^^4^^\n\n[[9.1 - Rethinking Land Productivity]]\n\n[[9.2 - Raising Water Productivity]]\n\n[[9.3 - Producing Protein More Efficiently]]\n\n[[9.4 - New Protein Production Systems]]\n\n[[9.5 - Moving Down the Food Chain]]\n\n[[9.6 - Action on Many Fronts]]\n\n[[9.7 - Additional Resources]]\n\n[[9.8 - Notes]]\n\n[[10 - Stabilizing Climate]]\n\n----\nDownload pdf version of Chapter 9\n\n 19pp. (88 Kb)
Efforts to raise cropland productivity are slowing as the backlog of unused agricultural technology shrinks. The loss of momentum in efforts to raise cropland productivity is worldwide. Between 1950 and 1990, world grain yield per hectare climbed by 2.1 percent a year. From 1990 to 2000, however, it rose only\n\n1.2 percent annually. This is partly because the yield response to the additional application of fertilizer is diminishing and partly because irrigation water supplies are limited. During the current decade, the rise in land productivity may slow even more.^^5^^\n\nThis calls for fresh thinking on how to raise cropland productivity. One simple way of doing this, where soil moisture permits, is to increase the area multicropped - land that produces more than one crop per year. In North America and Western Europe, which in the past have restricted cropped area to control surpluses, there is some potential for double cropping that has not been fully exploited. Indeed, the tripling in the world grain harvest since 1950 is due in part to impressive increases in multiple cropping in Asia. Some of the more common combinations are wheat and corn in northern China, wheat and rice in northern India, and the double or triple cropping of rice in southern China, southern India, and nearly all the rice-growing countries in Southeast Asia.^^6^^\n\nThe double cropping of winter wheat and corn in the North China Plain boosted China's grain production to the U.S. level beginning two decades ago. Winter wheat grown there yields close to 4 tons per hectare. Corn averages 5 tons. Together these two crops, grown in rotation, can yield 9 tons of grain per hectare per year. China's double-cropped rice yields 8 tons per hectare.^^7^^\n\nForty years ago, North India produced only wheat, but with the advent of the earlier maturing high-yielding wheats and rices, the wheat could be harvested in time to plant rice. This wheat/rice combination is now widely used throughout the Punjab, Haryana, and parts of Uttar Pradesh. The wheat yield of 3 tons and rice yield of 2 tons combine for 5 tons of grain per hectare, helping to feed India's 1.1 billion people.^^8^^\n\nThe area that can be multicropped is limited by the supply of irrigation water and, in some areas, by a lack of enough labor to quickly harvest one crop and plant another. The loss of low-cost rural labor to industrialization can sharply reduce multiple cropping and therefore the harvested area. In Japan, for example, the grain harvested area peaked at nearly 5 million hectares in 1960 largely because the country's industrious farmers were harvesting two crops per year. As of 2005, Japan's harvested area had dropped to 2 million hectares in part because of cropland conversion to nonfarm uses, but mostly because of a steady decline in double cropping over the decades as rising wages in industry pulled workers away from agriculture. The cheap labor needed to cultivate small plots intensively has disappeared. Even a rice support price four times the world market level could not keep enough workers in agriculture to support extensive multicropping.^^9^^\n\nSimilarly, South Korea's harvested grain area has shrunk by half since peaking in 1965 primarily because of a decline in multiple cropping. Taiwan's has declined nearly two thirds since 1975. As industrialization progresses in China and India, their more prosperous regions may see similar declines in multiple cropping. In China, where incomes have quadrupled since 1980, this process already appears to be reducing production.^^10^^\n\nIn the United States, the lifting of planting area restrictions in 1996 opened new opportunities for multiple cropping. The most common U.S. double cropping combination is winter wheat with soybeans as a summer crop. Six percent of the soybean harvest comes from land that also produces winter wheat. Since soybeans fix nitrogen, this rotation reduces wheat farmers' need to apply fertilizer.^^11^^\n\nA concerted U.S. effort to both breed earlier maturing varieties and develop cultural practices that would facilitate multiple cropping could substantially boost crop output. If China's farmers can extensively double crop wheat and corn, then U.S. farmers, at a similar latitude and with similar climate patterns, could do the same if agricultural research and farm policy were reoriented to support it.\n\nWestern Europe, with its mild winters and high-yielding winter wheat, might also be able to double crop more with a summer grain, such as corn, or with an oilseed crop. Elsewhere, Brazil and Argentina have an extended frost-free growing season that supports extensive multicropping, often wheat or corn with soybeans. The availability of chemical fertilizers also facilitates multiple cropping.^^12^^\n\nIn many countries, including the United States, most of those in Western Europe, and Japan, fertilizer use has reached a level where using more has little effect on crop yields. There are still some places, however, such as most of Africa, where additional fertilizer would help boost yields. Unfortunately, sub-Saharan Africa lacks the infrastructure to transport fertilizer economically to the villages where it is needed. As a result of nutrient depletion, grain yields in much of sub-Saharan Africa are falling.^^13^^\n\nOne encouraging response to this situation in Africa is the simultaneous planting of grain and leguminous trees. The trees start to grow slowly, permitting the grain crop to mature and be harvested. Then the trees grow quickly to several feet in height, dropping leaves that provide nitrogen and organic matter - both sorely needed in African soils. The wood is then cut and used for fuel. This simple, locally adapted technology, developed by scientists at the International Centre for Research in Agroforestry in Nairobi, has enabled farmers to double their grain yields within a matter of years as soil fertility builds.^^14^^\n\nDespite local advances, the overall loss of momentum in expanding food production is unmistakable. It will force us to think about both limiting the growth in demand and using the existing harvest more productively. On the demand side, achieving an acceptable worldwide balance between food and people may now depend on stabilizing population as soon as possible, reducing the unhealthily high consumption of livestock products in industrial countries, and restricting the conversion of food crops to automotive fuels. But we must also think more broadly about land productivity, considering not only the individual crop but how to increase multiple cropping and how to get more out of existing harvests.\n\n[[9.2 - Raising Water Productivity]]\n\n[[9.3 - Producing Protein More Efficiently]]\n\n[[9.4 - New Protein Production Systems]]\n\n[[9.5 - Moving Down the Food Chain]]\n\n[[9.6 - Action on Many Fronts]]\n\n[[9.7 - Additional Resources]]\n\n[[9.8 - Notes]]\n\n[[10 - Stabilizing Climate]]
Since it takes 1,000 tons of water to produce 1 ton of grain, it is not surprising that 70 percent of world water use is devoted to irrigation. Thus, raising irrigation water efficiency is central to raising water productivity overall. Using more water-efficient irrigation technologies and shifting to crops that use less water can help expand the irrigated area, even with a limited water supply. Eliminating water subsidies and energy subsidies that encourage wasteful water use allows water prices to rise to market levels. Higher water prices encourage all water users to use water more efficiently. Institutionally, local rural water users associations that directly involve those using the water in its management have raised water productivity in many countries.^^15^^\n\nThe world now needs to launch an effort to raise water productivity similar to the one that nearly tripled grainland productivity during the last half of the twentieth century. Land productivity is typically measured in tons of grain per hectare or bushels per acre. A comparable indicator for irrigation water is kilograms of grain produced per ton of water. Worldwide, that average is now roughly 1 kilogram of grain per ton of water used.^^16^^\n\nSome data have been compiled on water irrigation efficiency at the international level for surface water projects - that is, dams that deliver water to farmers through a network of canals. Crop usage of irrigation water never reaches 100 percent simply because some irrigation water evaporates from the land surface, some percolates downward, and some runs off.^^17^^\n\nWater policy analysts Sandra Postel and Amy Vickers found that "surface water irrigation efficiency ranges between 25 and 40 percent in India, Mexico, Pakistan, the Philippines, and Thailand; between 40 and 45 percent in Malaysia and Morocco; and between 50 and 60 percent in Israel, Japan, and Taiwan." Irrigation water efficiency is affected not only by the type and condition of irrigation systems but also by soil type, temperature, and humidity. In arid regions with high temperatures, the evaporation of irrigation water is far higher than in humid regions with lower temperatures.^^18^^\n\nIn a May 2004 meeting, China's Minister of Water Resources Wang Shucheng outlined for me in some detail the plans to raise China's irrigation efficiency from 43 percent in 2000 to 51 percent in 2010 and then to 55 percent in 2030. The steps he described included raising the price of water, providing incentives for adopting more irrigation-efficient technologies, and developing the local institutions to manage this process. Reaching these goals, he felt, would assure China's future food security.\n\nRaising irrigation water efficiency typically means shifting from the less efficient flood or furrow system to overhead sprinklers or to drip irrigation, the gold standard of irrigation efficiency. Switching from flood or furrow to low-pressure sprinkler systems reduces water use by an estimated 30 percent, while switching to drip irrigation typically cuts water use in half.^^20^^\n\nAs an alternative to furrow irrigation, a drip system also raises yields because it provides a steady supply of water with minimal losses to evaporation. Since drip systems are both labor-intensive and water-efficient, they are well suited to countries with underemployment and water shortages, allowing farmers to raise their water productivity by using labor, which is often in surplus in rural communities.^^21^^\n\nA few small countries - Cyprus, Israel, and Jordan - rely heavily on drip irrigation. Among the big three agricultural producers, this more-efficient technology is used on less than 1 percent of irrigated land in India and China and roughly 4 percent of such land in the United States.^^22^^\n\nIn recent years, the tiniest small-scale drip-irrigation systems - virtually a bucket with flexible plastic tubing to distribute the water - have been developed to irrigate a small vegetable garden with roughly 100 plants (covering 25 square meters). Somewhat larger drum systems irrigate 125 square meters. In both cases, the containers are elevated slightly, so that gravity distributes the water. Somewhat larger drip systems using plastic lines that can be moved easily are also becoming popular. These simple systems can pay for themselves in one year. By simultaneously reducing water costs and increasing yields, they can dramatically raise incomes of smallholders.^^23^^\n\nSandra Postel believes that the combination of these drip technologies at various scales has the potential to profitably irrigate 10 million hectares of India's cropland, or nearly one tenth of the total. She sees a similar potential for China, which is now also expanding its drip irrigation area to save scarce water.^^24^^\n\nInstitutional shifts - specifically, moving the responsibility for managing irrigation systems from government agencies to local water users associations - can facilitate a more efficient use of water. Farmers in many countries are organizing locally so they can assume this responsibility. Since local people have an economic stake in good water management, they tend to do a better job than a distant government agency.\n\nMexico is a leader in this movement. As of 2002, farmers associations managed more than 80 percent of Mexico's publicly irrigated land. One advantage of this shift for the government is that the cost of maintaining the irrigation system is assumed locally, reducing the drain on the treasury. This also means that associations often need to charge more for irrigation water. Even so, for farmers the production gains from managing their water supply more than outweigh this additional expenditure.^^26^^\n\nIn Tunisia, where water users associations manage both irrigation and residential water, the number of associations increased from 340 in 1987 to 2,575 in 1999. Many other countries now have such bodies managing their water resources. Although the early groups were organized to deal with large publicly developed irrigation systems, some recent ones have been formed to manage local groundwater irrigation as well. They assume responsibility for stabilizing the water table with the goal of avoiding aquifer depletion and the economic disruption that it brings to the community.\n\nLow water productivity is often the result of low water prices. In most countries, prices are irrationally low, belonging to an era when water was an abundant resource. As water becomes scarce, it needs to be priced accordingly. Provincial governments in northern China are raising water prices in small increments to discourage waste. A higher water price affects all water users, encouraging investment in more water-efficient irrigation technologies, industrial processes, and household appliances.^^28^^\n\nWhat is needed now is a new mindset, a new way of thinking about water use. For example, shifting to more water-efficient crops wherever possible also boosts water productivity. Rice production is being phased out around Beijing because rice is such a thirsty crop. Similarly, Egypt restricts rice production in favor of wheat.^^29^^\n\nAny measures that raise crop yields on irrigated land also raise the productivity of irrigation water. Similarly, anything that increases the efficiency with which grain is converted into animal protein in effect increases water productivity.\n\nFor people consuming unhealthy amounts of livestock products, moving down the food chain means not only a healthier diet and reduced health care costs but also a reduction in water use. In the United States, where annual consumption of grain as food and feed averages some 800 kilograms (four fifths of a ton) per person, a modest reduction in the consumption of meat, milk, and eggs could easily cut grain use per person by 100 kilograms. Given that there are now nearly 300 million Americans, such a reduction would cut grain use by 30 million tons and irrigation water use by 30 billion tons.^^30^^\n\nReducing water use to a level that can be sustained by aquifers and rivers worldwide involves a wide range of measures not only in agriculture but throughout the economy. The more obvious steps, in addition to more water-efficient irrigation practices and more water-efficient crops, include adopting more water-efficient industrial processes and using more water-efficient household appliances. One of the less conventional steps is to shift from outdated coal-fired power plants, which require vast amounts of water for thermal cooling, to wind power - something long overdue in any case because of climate disruption. Recycling urban water supplies is another obvious step to consider in countries facing acute water shortages.\n\n[[9.3 - Producing Protein More Efficiently]]\n\n[[9.4 - New Protein Production Systems]]\n\n[[9.5 - Moving Down the Food Chain]]\n\n[[9.6 - Action on Many Fronts]]\n\n[[9.7 - Additional Resources]]\n\n[[9.8 - Notes]]\n\n[[10 - Stabilizing Climate]]
The second way to raise both land and water productivity is to produce animal protein more efficiently. With some 38 percent (about 730 million tons) of the world grain harvest used to produce animal protein, the potential for more-efficient grain use is large.^^31^^\n\nWorld meat consumption increased from 47 million tons in 1950 to 260 million tons in 2005, more than doubling consumption per person from 17 kilograms to 40 kilograms. Consumption of milk and eggs has also risen. In every society where incomes have risen, meat consumption has too, perhaps reflecting a taste that evolved over 4 million years of hunting and gathering.^^32^^\n\nAs both the oceanic fish catch and the production of beef on rangelands have leveled off, the world has shifted to grain-based production of animal protein to expand output. And as the demand for animal protein climbs, the mix of protein products consumed is shifting toward those that convert grain into protein most efficiently, the lower-cost products. Health concerns have also prompted a shift from beef and pork to poultry and fish.\n\nThe efficiency with which various animals convert grain into protein varies widely. With cattle in feedlots, it takes roughly 7 kilograms of grain to produce a 1-kilogram gain in live weight. For pork, the figure is close to 4 kilograms of grain per kilogram of weight gain, for poultry it is just over 2, and for herbivorous species of farmed fish (such as carp, tilapia, and catfish), it is less than 2. As the market shifts production to the more grain-efficient products, it raises the productivity of both land and water.^^33^^\n\nGlobal beef production, most of which comes from rangelands, grew less than 1 percent a year from 1990 to 2005. Growth in the number of cattle feedlots was minimal. Pork production grew by 2.5 percent annually, and poultry by nearly 5 percent. The rapid growth in poultry production, going from 41 million tons in 1990 to 80 million tons in 2005, enabled poultry to eclipse beef in 1995, moving it into second place behind pork. (See Figure 9-1.) World pork production, half of it in China, overtook beef production in 1979 and has continued to widen the lead since then. World beef production, constrained by both grazing limits and the inefficient feedlot conversion by cattle, is continuing to expand, but slowly. Indeed, within the next decade or so, fast-growing, highly grain-efficient aquacultural output may overtake beef production.^^34^^\n\n<<tiddler Figure 9-1>>\n\nThe big winner in the animal protein sweepstakes has been aquaculture, largely because herbivorous fish convert feed into protein so efficiently. Aquacultural output expanded from 13 million tons in 1990 to 42 million tons in 2003, growing by more than 10 percent a year. China, the leading producer, accounts for an astounding two thirds of global output. Aquacultural production in China is dominated by finfish (mostly carp), which are produced inland in freshwater ponds, lakes, reservoirs, and rice paddies, and by shellfish (mostly oysters, clams, and mussels), which are produced mostly in coastal regions.^^35^^\n\nChina's aquaculture is often integrated with agriculture, enabling farmers to use agricultural wastes, such as pig or duck manure, to fertilize ponds, thus stimulating the growth of plankton on which the fish feed. Fish polyculture, which commonly boosts pond productivity over that of monocultures by at least half, is widely practiced in both China and India.^^36^^\n\nAs land and water for fish ponds become even scarcer, China's fish farmers are feeding fish more grain concentrates, including soybean meal, to raise pond productivity. Using this technique, China's farmers raised the annual pond yield per hectare from 2.4 tons of fish in 1990 to 4.1 tons in 1996.^^37^^\n\nIn the United States, catfish, which require less than 2 kilograms of feed per kilogram of live weight, are the leading aquacultural product. U.S. annual catfish production of 600 million pounds (about two pounds per person) is concentrated in four states: Mississippi, Louisiana, Alabama, and Arkansas. Mississippi, with easily 60 percent of U.S. output, is the catfish capital of the world.^^38^^\n\nPublic attention has focused on aquacultural operations that are environmentally inefficient or disruptive, such as the farming of salmon, a carnivorous species, and shrimp. These operations account for 3.6 million tons of output, less than 9 percent of the global farmed fish total, but they are growing fast. Salmon are inefficient in that they are fed other fish, usually as fishmeal, which comes either from fish processing plant wastes or from low-value fish caught specifically for this purpose. Shrimp farming often involves the destruction of coastal mangrove forests to create areas for the shrimp.^^39^^\n\nWorld aquaculture is dominated by herbivorous species - mainly carp in China and India, but also catfish in the United States and tilapia in several countries - and shellfish. This is where the great growth potential for efficient animal protein production lies.^^40^^\n\nWhen we think of soybeans in our daily diet, it is typically as tofu, veggie burgers, or other meat substitutes. But most of the world's fast-growing soybean harvest is consumed indirectly in the beef, pork, poultry, milk, eggs, and farmed fish that we eat. Although not a visible part of our diets, the incorporation of soybean meal into feed rations has revolutionized the world feed industry, greatly increasing the efficiency with which grain is converted into animal protein.^^41^^\n\nIn 2005, the world's farmers produced 220 million tons of soybeans - 1 ton for every 9 tons of grain produced. Of this, some 15 million tons were consumed directly as tofu or meat substitutes. The bulk of the remaining 205 million tons, after some was saved for seed, was crushed in order to extract 33 million tons of soybean oil, separating it from the highly valued, high-protein meal. By 2006, perhaps 2 million tons (7 percent) of these 33 million tons will be heading to service stations as biodiesel.^^42^^\n\nThe 144 million tons of soybean meal that remain after the oil is extracted is fed to cattle, pigs, chicken, and fish, enriching their diets with high-quality protein. Combining soybean meal with grain in roughly one part meal to four parts grain dramatically boosts the efficiency with which grain is converted into animal protein, sometimes nearly doubling it.^^43^^\n\nThe world's three largest meat producers - China, the United States, and Brazil - now all rely heavily on soybean meal as a\n\n//174 PLAN B 2.0//\n\nprotein supplement in feed rations. In the United States, which has long used soybean meal to upgrade livestock and poultry feed, the soybean meal share of feed rations climbed from 8 percent in 1964 to roughly 18 percent in recent years.^^44^^\n\nFor Brazil, where the shift began in the late 1980s, soybean meal now makes up roughly 21 percent of the feed mix. In China, the realization that feed efficiency could be dramatically boosted with soymeal came several years later. Between 1991 and 2002, the soymeal component of feed there jumped from 2 percent to 20 percent. For fish, whose protein demands are particularly high, China incorporated some 5 million tons of soymeal into the 16 million tons of grain-based fish feed used in 2003.^^45^^\n\nWith this phenomenal growth, soybean meal both replaced some grain in feed and increased the efficiency with which the remaining grain was converted into livestock products. This also helps explain why the share of the world grain harvest used for feed has not increased over the last 20 years even though production of meat, milk, eggs, and farmed fish has climbed. And it explains why world soybean production jumped from 16 million tons in 1950 to 220 million tons in 2005, a 13-fold increase. While the potential for raising feed efficiency with soybean meal has now been largely realized in key food-producing countries, there are still many developing countries that have not yet fully exploited its potential.^^46^^\n\n[[9.4 - New Protein Production Systems]]\n\n[[9.5 - Moving Down the Food Chain]]\n\n[[9.6 - Action on Many Fronts]]\n\n[[9.7 - Additional Resources]]\n\n[[9.8 - Notes]]\n\n[[10 - Stabilizing Climate]]
Mounting pressures on the earth's land and water resources to produce livestock, poultry, and fish feed have led to the evolution of some promising new animal protein production models, one of which is milk production in India. Since 1970, India's milk production has increased more than fourfold, jumping from 21 million to 95 million tons. In 1998, India overtook the United States to become the world's leading producer of milk and other dairy products. (See Figure 9-2.)^^47^^\n\n<<tiddler Figure 9-2>>\n\nThe spark for this explosive growth came in 1965 when an enterprising young Indian, Dr. Verghese Kurien, organized the National Dairy Development Board, an umbrella organization of dairy cooperatives. The dairy coop's principal purpose was to market the milk from tiny herds that typically averaged two to three cows each, providing the link between the growing appetite for dairy products and the millions of village families who had only a small marketable surplus.^^48^^\n\nCreating the market for milk spurred the fourfold growth in output. In a country where protein shortages stunt the growth of so many children, expanding the milk supply from less than half a cup per person a day 30 years ago to more than a cup represents a major advance.^^49^^\n\nWhat is so remarkable is that India has built the world's largest dairy industry almost entirely on roughage - wheat straw, rice straw, corn stalks, and grass collected from the roadside. Even so, the value of the milk produced each year now exceeds that of the rice harvest.^^50^^\n\nA second new protein production model, one that also relies on ruminants, has evolved in four provinces of central Eastern China - Hebei, Shangdong, Henan, and Anhui - where double cropping of winter wheat and corn is common. Once the winter wheat ripens in early summer, it is harvested quickly so the seedbed can be prepared for the corn. Similarly, once the corn is harvested in the fall, the seedbed is quickly prepared to sow the wheat. Although the wheat straw and cornstalks are often used as fuel for cooking, villagers are shifting to other sources of energy for this, which lets them feed the straw and cornstalks to cattle. Supplementing this roughage with small amounts of nitrogen in the form of urea allows the microflora in the complex four-stomach digestive system of cattle to convert roughage into animal protein efficiently.\n\nThese four crop-producing provinces in China, dubbed the Beef Belt by officials, produce much more beef, using crop residues - wheat and rice straw and corn stalks - than the vast grazing provinces in the northwest do. The use of crop residues to produce milk in India and beef in China lets farmers reap a second harvest from the original grain crop, boosting both land and labor productivity.\n\nOver time, China has also developed a remarkably efficient fish polyculture using four types of carp that feed at different levels of the food chain, in effect emulating natural aquatic ecosystems. Silver carp and bighead carp are filter feeders, eating phytoplankton and zooplankton respectively. The grass carp, as its name implies, feeds largely on vegetation, while the common carp is a bottom feeder, living on detritus. These four species thus form a small ecosystem, with each filling a particular niche. This multi-species system, which converts feed into high-quality protein with remarkable efficiency, yielded some 13 million tons of carp in 2002.^^53^^\n\nWhile poultry production has grown rapidly in China, as in other developing countries, it has been dwarfed by the phenomenal growth of aquaculture. Today aquacultural output in China - at 29 million tons - is double that of poultry, making it the first major country where aquaculture has eclipsed poultry farming. The great economic and environmental attraction of this system is the efficiency with which it produces animal protein.^^54^^\n\nAlthough these three new protein models have evolved in India and China (both densely populated), similar systems can be adopted in other countries as population pressures intensify, as demand for meat and milk increase, and as farmers seek new ways to convert plant products into animal protein.\n\nThe world desperately needs more new protein production techniques such as these. A half-century ago, when there were only 2.5 billion people in the world, almost everyone wanted to move further up the food chain. Now that number may have doubled. Meat consumption is growing twice as fast as population, egg consumption is growing nearly three times as fast, and growth in the demand for fish - both from the oceans and from fish farms - is also outpacing that of population. Against this backdrop of growing world demand, human ingenuity in producing animal protein in ever-larger quantities and ever more efficiently will be tested.^^55^^\n\nWhile the world has had many years of experience in feeding an additional 70 million or more people each year, it has no experience with some 5 billion people wanting to move up the food chain at the same time. For a sense of what this translates into, consider what has happened in China since the economic reforms in 1978. As the fastest-growing economy in the world since then, China has in effect telescoped history, showing how diets change when incomes rise rapidly.\n\nAs recently as 1978, meat consumption was low in China, consisting mostly of modest amounts of pork. Since then, consumption of pork, beef, poultry, and mutton has climbed severalfold, pushing China's total meat consumption far above that of the United States. As incomes rise in other countries, consumers there will also want more animal protein. Considering the effect of this expanding demand on global land and water resources, along with the more traditional demand from population growth, provides a better sense of future pressures on the earth. If world grain supplies tighten in the years ahead, the competition for grain between people wanting more biofuels, those living high on the food chain, and those on the bottom rungs of the economic ladder will become both more visible and a possible source of tension within and among societies.^^57^^\n\n[[9.5 - Moving Down the Food Chain]]\n\n[[9.6 - Action on Many Fronts]]\n\n[[9.7 - Additional Resources]]\n\n[[9.8 - Notes]]\n\n[[10 - Stabilizing Climate]]
One of the questions I am most often asked on a speaking tour is, "How many people can the earth support?" I answer with another question: "At what level of food consumption?" At the\n\nU.S. level of 800 kilograms per person per year for food and feed, the 2-billion-ton annual world harvest of grain would support 2.5 billion people. At the Italian level of consumption of close to 400 kilograms per year, the current harvest would support 5 billion people. At the nearly 200 kilograms of grain consumed per year by the average Indian, it would support a population of 10 billion.^^58^^\n\nIn every society where incomes rise, people move up the food chain, eating more animal protein as beef, pork, poultry, milk, eggs, and seafood. The mix of animal protein products varies with geography and culture, but the shift to more animal protein as purchasing power increases appears to be universal.\n\nAs consumption of livestock products, poultry, and farmed fish rises, grain use per person also rises. Of the roughly 800 kilograms of grain consumed per person each year in the United States, about 100 kilograms is eaten directly as bread, pasta, and breakfast cereals. But the bulk of the grain is consumed indirectly in the form of livestock, poultry, and farmed fish. By contrast, in India, where people consume just under 200 kilograms of grain per year, or roughly a pound per day, nearly all grain is eaten directly to satisfy basic food energy needs. Little is available for conversion into livestock products.^^59^^\n\nOf the three countries just cited, life expectancy is highest in Italy even though U.S. expenditures on medical care per person are much higher. Those who live very low on the food chain or very high on the food chain do not live as long as those in an intermediate position. The Mediterranean diet includes meats, cheeses, and seafood, but in moderation. Nutritionally, this is the healthiest way to eat.^^60^^\n\nWhat this means is that those living high on the food chain, such as the average American or Canadian, can consume less grain and improve health at the same time. For those who live in low-income countries like India, where diets are dominated by a starchy staple such as rice, sometimes supplying 60 percent or more of total caloric intake, eating more animal products can improve health and raise life expectancy.\n\nIn addition to having the affluent sector move down the food chain by consuming fewer livestock products, the world is turning to the more grain-efficient forms of animal protein. Together these two steps have helped hold the share of the world grain harvest used for feed constant at roughly 38 percent for the last two decades.^^62^^\n\nIt is widely assumed that moving from animal protein to high-quality proteins from plant sources, such as beans or tofu made from soybeans, is more land-efficient. But this is not always the case. For example, as noted earlier, with poultry it takes just over 2 kilograms of grain to produce 1 kilogram of additional live weight. For catfish, it is less than 2 kilograms of grain per kilogram of weight gain. An acre of land in Iowa can thus produce 140 bushels of corn or 35 bushels of the much lower-yielding soybean. Feeding the corn to chickens or catfish can yield more high-quality protein than growing soybeans and consuming them directly, say as tofu.^^63^^\n\nIt takes a good deal of land to produce soy protein, largely because plants require more metabolic energy to produce high-quality plant protein than to produce starch. But because poultry and catfish are so efficient at converting grain, eating them is more land- and water-efficient than eating soybeans is.^^64^^\n\nSome countries are moving down the food chain by turning to the more grain-efficient protein sources such as aquaculture. China, with its huge aquacultural output, may be the first country where the farmed fish harvest exceeds the wild fish catch.^^65^^\n\nWith incomes now rising in densely populated Asia, other countries are following China's lead. Among them are India, Thailand, and Viet Nam. Viet Nam, for example, devised a plan in 2001 of developing 700,000 hectares of land in the Mekong Delta for aquaculture, with the goal of producing 1.7 million tons of fish and shrimp by 2005. It now appears likely to exceed this goal.^^66^^\n\n[[9.6 - Action on Many Fronts]]\n\n[[9.7 - Additional Resources]]\n\n[[9.8 - Notes]]\n\n[[10 - Stabilizing Climate]]
Historically, the responsibility for food security rested largely with the ministry of agriculture. During the last half of the last century, ensuring adequate supplies of grain in the world market was a relatively simple matter. Whenever the world grain harvest fell short and prices started to rise, the U.S. Department of Agriculture would simply return to production part of the cropland idled under supply control programs, thus boosting output and stabilizing prices. This era ended in 1996 when the United States dismantled its annual cropland set-aside program.^^67^^\n\nMinistries of agriculture bear the primary responsibility for expanding food production to satisfy the world's seemingly insatiable appetite. The fast-growing demand from the addition of 70 million mouths to feed each year, from 5 billion people wanting to move up the food chain, and now, for the first time, from the insatiable demand for farm commodities to produce automotive fuel will pose an unprecedented challenge to ministries of agriculture. At the same time they are faced with a dwindling backlog of unused agricultural technology, shrinking supplies of irrigation water, and the prospect of crop-withering heat waves. Demand growth and supply constraints together will challenge agricultural leaders as never before.\n\nIn this chapter, we have discussed some of the newer measures that can be used to raise land and water productivity. Adoption of these and other actions are obviously important, but in the new world we have entered, the policies of other ministries also bear heavily on the food security prospect.\n\nNow with our finite planet being pushed to its limits and beyond, the capacity of health and family planning ministries to educate the public about the consequences of population growth and to meet family planning needs has become a food security issue. Whether individual couples decide to have one, two, or three children directly affects world food security.\n\nIn today's world, decisions made in ministries of energy on whether to stay with fossil fuels and continue to drive the earth's temperature upward or to shift to renewable energy sources and stabilize the earth's temperature could have a greater effect on long-term food security than any actions taken by ministries of agriculture.\n\nAnd in much of the world, water is a more serious constraint on food production than land. The success, or lack thereof, of water ministries in raising water productivity will directly affect future food security and food prices.\n\nSimilarly, in a world where cropland is scarce and becoming more so, decisions made in ministries of transportation on whether to develop auto-centered systems or more diversified transport systems that rely heavily on less land-intensive transport forms, including light rail, buses, and bicycles will also affect world food security. Policies adopted by the ministers of transportation in land-scarce countries like China and India directly affect world food security.\n\nMore broadly, how far governments go in encouraging the use of scarce agricultural resources to produce commodities to be converted into automotive fuel will directly affect efforts to eradicate hunger. The question is how effective governments will be in managing this emerging competition between cars and people for food commodities.\n\nIn our increasingly crowded world, the responsibility for food security extends far beyond the ministry of agriculture, involving all ministries in the effort to fully realize the earth's sustainable food production potential. At the same time, there are many agricultural successes that can be imported by countries struggling to improve their food security. Encouragingly, the two big breakthroughs in expanding animal protein sup-plies - the dramatic gains in milk production in India and fish farming in China - can be replicated in many other developing countries.\n\n[[9.7 - Additional Resources]]\n\n[[9.8 - Notes]]\n\n[[10 - Stabilizing Climate]]

Lester R. Brown is President of Earth Policy Institute - - a nonprofit, interdisciplinary research organization based in Washington, D.C., which he founded in May 2001. The purpose of the Earth Policy Institute is to provide a vision of an environmentally sustainable economy and a roadmap of how to get from here to there.\n\nBrown has been described as "one of the world's most influential thinkers" by the //Washington Post//. The //Telegraph// of Calcutta called him "the guru of the environmental movement." In 1986, the Library of Congress requested his papers for their archives.\n\nSome 30 years ago, Brown helped pioneer the concept of environmentally sustainable development, a concept he uses in his design of an eco-economy. He was the Founder and President of the Worldwatch Institute during its first 26 years. During a career that started with tomato farming, Brown has authored or coauthored many books and been awarded over 20 honorary degrees. His books have appeared in more than 40 languages.\n\nBrown is a MacArthur Fellow and the recipient of countless prizes and awards, including the 1987 United Nations Environment Prize, the 1989 World Wide Fund for Nature Gold Medal, and the 1994 Blue Planet Prize for his "exceptional contributions to solving global environmental problems." In 1995, Marquis //Who's Who//, on the occasion of its fiftieth edition, selected Lester Brown as one of 50 Great Americans. Most recently he was awarded the Presidential Medal of Italy and the Borgström Prize by the Royal Swedish Academy of Agriculture and Forestry, and he was appointed an honorary professor of the Chinese Academy of Sciences. He lives in Washington, D.C.\n\n----\nDownload pdf version of About the Author\n\n 1pp. (45 Kb)
This web site is based on a TiddlyWiki platform - a unique and brilliant design for a self-contained, [[Creative Commons]] "Wiki". Wiki is a Hawaiian word meaning //swift// or //swiftly//, and TiddlyWiki is the wikiest wiki to date., Unlike most web sites that consist of multiple, linked web pages, all of the content in a TiddlyWiki is contained in a single web page, that contains numerous sub-pages, known as "tiddlers".\n\nThe site also serve as one of the elements of [[Climate Change 2.0]], an open initiative designed to harness the powers of information and communications technology in conjunction with broad-based participation of all elements of society in response to the economic, social and environmental dimensions of the climate change crisis.\n\nA TiddlyWiki page uses simple formatting codes for its tiddlers - similar, but not identical to the codes used in <<wikipedia Wikipedia>> and each tiddler can have one or more "tags" or "key words" that are displayed adjacent to the tiddler. This makes TiddlyWiki the easiest and quickest platform for creating and maintaining a web site.\n\nFrom a design standpoint, what makes TiddlyWiki unique is that not only can tiddlers contain and siplay text, images, links, etc, but the appearance and format of a TiddlyWiki is defined by "style sheets and "styles" that are themselves contained in tiddlers. In addition, a tiddler can include Javascript - the language that powers TiddlyWiki - that can add very useful features over and above those in the standard TiddlyWiki.\n

<<<\n"No problem can be solved from the same level of consciousness that created it."\n//Albert Einstein// (1879 - 1955) Physicist & Nobel Laureate \n<<<\n''Climate Change 2.0'' - [[|]] - is being developed from a vision of a collaborative application of [[Web 2.0]] methodologies to the global [[climate change crisis|Climate change crisis]] and incorporating a transition to an [[Open Source]], [[Creative Commons]] climate. ''Climate Change 2.0'' is based on the recognition of the vital contribution that the combination of the [[economics of information|Economics of information]] and information and communications technologies (ICT) can contribute - and already are contributing - to addressing what is increasingly recognized as the greatest challenges to a sustainable common future, through enabling a profound transition to a consciousness ...\n<<<\n"''The Interlocking Crises''\nUntil recently, the planet was a large world in which human activities and their effects were neatly compartmentalized within nations, within sectors (energy, agriculture, trade), and within broad areas of concern (environment, economics, social). These compartments have begun to dissolve. This applies in particular to the various global 'crises' that have seized public concern, particularly over the past decade. These are not separate crises: an environmental crisis, a development crisis, an energy crisis. They are all one."\n//[[Our Common Future, From One Earth to One World|]]//\n<<<\nIn ''Climate Change 2.0''\n\nDespite the fact that ICT has made indispensable contributions to the understanding of climate change. the lack of recognition of the current and potential role of ICT - and of the [[economics of information|Economics of information]], in addressing the climate change crisis is striking. Among the many contributions of ICT are the:\n* collection and analysis of the evidence demonstrating the nature and dynamics of climate change would not be possible;\n* use of earth observation satellite imagery\n* extensive and timely collaboration among thousands of research scientists, advocates and activists concerned with climate change;\n* use of the Internet as a key medium in the publication and dissemination of information and publications relating to climate change trends\nHowever, while there is a massive amount of information freely available online in relation to climate change,\n* there is no systematic strategy to optimize the organization of climate change information for a digital environment\n* almost all of the major documents are published as pdf files - a format optimized for printing - and that offers fairly primitive and cumbersome navigational features compared to the combination of HTML, scripting languages and database-driven methodologies\n* the pdf files are generally created without even the incorporation of internal pdf navigational tools, i.e. bookmarks, or with systematic inclusion of hyperlinks to references\nIn addition. although there are some excellent examples of the value of process-oriented ICT, little attention is given to the actual and potential use of ICT in such areas as:\n* monitoring and analyzing industrial energy & resource use, often within the conceptual framework of ''industrial ecology'' - see <<wikipedia "Industrial ecology">> at <<wikipedia Wikipedia>>.\n* monitoring and management of residential & office energy use\n* monitoring and management of traffic congestion & traffic flows\n* energy-saving through substituting the movement of information for the movement of people\n!!![[Background / Context]]\n!!![[Draft Plan of Action]]\n!!![[Current Status]]\n!!![[Related Initiatives]]
To date a number of elements of Climate 2.0 have been under development, with a short-term focus on the development of an online platform for the September 2007 ''60th Annual DPI/NGO Conference'' - on the theme of Climate Change in , and in the broader context of the [[NGO Committee on Education]]'s focus on the [[United Nations Decade of Education for Sustainable Development]], 2005-2014, and related international decades.\n\nThe DPI/NGO Climate Change Conference offers a unique opportunity for a demonstration project of [[Climate Change 2.0]] as it will be the last to be held at the United Nations Headquarters before major renovations begin, and there is strong interest in developing a prototype interactive online framework that would provide for real-time participation in the Conference, for this Conference, and as a model to be used for future Annual DPI/NGO Conferences.\n\nAmong the elements that are under development are the following:\n* [[Climate Change 2.0]]<br>[[|]]\n** [[Climate Change Impacts, Adaptation and Vulnerability]]<br>[[|]]\n** [[Rescuing a Planet Under Stress and a Civilization in Trouble: Plan B 2.1 (beta)]]<br>[[|]]\n** [[The Wealth of Networks: How Social Production Transforms Markets and Freedom]]<br>[[|]]\n** [[Economics of Climate Change: The Stern Review]]<br>[[|]]\n** [[Education, Youth & Technology for Sustainable Development]]<br>[[|]]\n** [[UN Documents Cooperation Circles: Gathering a Body of Global Agreements]]<br>[[|]]\n** [[TiddlyPerfect: An emerging hybrid information species]]<br>[[|]]

The contents of this TiddlyWiki web page were generated from a ''~DataPerfect'' database. ~DataPerfect is a little-known, brilliant relational database compantion of the legendary ''~WordPerfect for DOS'', which was used to prepare the text from the pdf files of The Stern Review for input into the ~DataPerfect database. The design of ~DataPerfect makes it an exceptional vehicle for generating content for TiddlyWiki web pages. \n\n~DataPerfect was written, and is still maintained by, ''Lew Bastian'' - older brother of ~WordPerfect's author, Bruce Bastian; before joining the ''~WordPerfect Corporation'', Lew had worked for ''IBM'', where he had written some of the early disk-caching patents. The development of ~DataPerfect was discontinued by the ''~WordPerfect Corporation'' after the introduction of Windows, and subsequently, Novell made the program freely available; an active ''~DataPerfect Users Group'' - [[|]] - of which Lew Bastian is a leading member - provides exceptional support.\n\nPartial & preliminary drafts of TiddlyPerfect site for DataPerfect is available at

To create a tiddler link when automatic linking is disabled, you must enclose the link text within {{{[[...]]}}}.\n\nYou can also block automatic WikiWord linking behavior only for non-existing tiddler titles, while still automatically linking WikiWords that correspond to existing tiddlers titles or shadow tiddler titles.\n\nYou can also block specific selected WikiWords from being automatically linked by listing them in [[DisableWikiLinksList]], separated by whitespace. This tiddler is optional and, when present, causes the listed words to always be excluded, even if automatic linking of other WikiWords is being permitted. \n\nNote: WikiWords contained in default ''shadow'' tiddlers will be automatically linked unless you select an additional checkbox option lets you disable these automatic links as well, though this is not recommended, since it can make it more difficult to access some TiddlyWiki standard default content (such as AdvancedOptions or SideBarTabs)\n\n!!!!!Configuration\n<<<\nSelf-contained control panel:\n<<option chkDisableNonExistingWikiLinks>> Disable automatic WikiWord links for non-existing tiddlers\n<<option chkDisableWikiLinks>> Disable ALL automatic WikiWord tiddler links\n<<option chkAllowLinksFromShadowTiddlers>> ... except for WikiWords contained in shadow tiddlers\n<<<\n!!!!!Installation\n<<<\nimport (or copy/paste) the following tiddlers into your document:\n''DisableWikiLinksPlugin'' (tagged with <<tag systemConfig>>)\n<<<\n!!!!!Revision History\n<<<\n''2006.12.31 [1.4.0]'' in formatter, test for chkDisableNonExistingWikiLinks\n''2006.12.09 [1.3.0]'' in formatter, test for excluded wiki words specified in DisableWikiLinksList\n''2006.12.09 [1.2.2]'' fix logic in autoLinkWikiWords() (was allowing links TO shadow tiddlers, even when chkDisableWikiLinks is TRUE). \n''2006.12.09 [1.2.1]'' revised logic for handling links in shadow content\n''2006.12.08 [1.2.0]'' added hijack of Tiddler.prototype.autoLinkWikiWords so regular (non-bracketed) WikiWords won't be added to the missing list\n''2006.05.24 [1.1.0]'' added option to NOT bypass automatic wikiword links when displaying default shadow content (default is to auto-link shadow content)\n''2006.02.05 [1.0.1]'' wrapped wikifier hijack in init function to eliminate globals and avoid FireFox crash bug when referencing globals\n''2005.12.09 [1.0.0]'' initial release\n<<<\n!!!!!Credits\n<<<\nThis feature was developed by EricShulman from [[ELS Design Studios|http:/]]\n<<<\n!!!!!Code\n***/\n//{{{\nversion.extensions.disableWikiLinks= {major: 1, minor: 4, revision: 0, date: new Date(2006,12,31)};\n\nif (config.options.chkDisableNonExistingWikiLinks==undefined) config.options.chkDisableNonExistingWikiLinks= false;\nif (config.options.chkDisableWikiLinks==undefined) config.options.chkDisableWikiLinks= false;\nif (config.options.chkAllowLinksFromShadowTiddlers==undefined) config.options.chkAllowLinksFromShadowTiddlers=true;\n\n// find the formatter for wikiLink and replace handler with 'pass-thru' rendering\ninitDisableWikiLinksFormatter();\nfunction initDisableWikiLinksFormatter() {\n for (var i=0; i<config.formatters.length && config.formatters[i].name!="wikiLink"; i++);\n config.formatters[i].coreHandler=config.formatters[i].handler;\n config.formatters[i].handler=function(w) {\n // supress any leading "~" (if present)\n var skip=(w.matchText.substr(0,1)==config.textPrimitives.unWikiLink)?1:0;\n var title=w.matchText.substr(skip);\n var exists=store.tiddlerExists(title);\n var inShadow=w.tiddler && store.isShadowTiddler(w.tiddler.title);\n\n // check for specific excluded wiki words\n var t=store.getTiddlerText("DisableWikiLinksList")\n if (t && t.length && t.indexOf(w.matchText)!=-1)\n { w.outputText(w.output,w.matchStart+skip,w.nextMatch); return; }\n\n // if not disabling links from shadows (default setting)\n if (config.options.chkAllowLinksFromShadowTiddlers && inShadow)\n return this.coreHandler(w);\n\n // check for non-existing non-shadow tiddler\n if (config.options.chkDisableNonExistingWikiLinks && !exists)\n { w.outputText(w.output,w.matchStart+skip,w.nextMatch); return; }\n\n // if not enabled, just do standard WikiWord link formatting\n if (!config.options.chkDisableWikiLinks)\n return this.coreHandler(w);\n\n // just return text without linking\n w.outputText(w.output,w.matchStart+skip,w.nextMatch)\n }\n}\n\nTiddler.prototype.coreAutoLinkWikiWords = Tiddler.prototype.autoLinkWikiWords;\nTiddler.prototype.autoLinkWikiWords = function()\n{\n // DEBUG alert("processing: "+this.title);\n // if all automatic links are not disabled, just return results from core function\n if (!config.options.chkDisableWikiLinks)\n return this.coreAutoLinkWikiWords.apply(this,arguments);\n return false;\n}\n//}}}\n

This ability is also very useful when moving your own tiddlers from document to document (e.g., when upgrading to the latest version of TiddlyWiki, or 'pre-loading' your favorite stylesheets into a new 'empty' TiddlyWiki document.)\n\nExportTiddlersPlugin let you ''select and extract tiddlers from your ~TiddlyWiki documents and save them to a local file'' or a remote server (requires installation of compatible server-side scripting, still under development...). An interactive control panel lets you specify a destination, and then select which tiddlers to export. A convenient 'selection filter' helps you pick desired tiddlers by specifying a combination of modification dates, tags, or tiddler text to be matched or excluded.

/***\n|''Name:''|ImportTiddlersPlugin|\n|''Source:''||\n|''Author:''|Eric Shulman - ELS Design Studios|\n|''License:''|[[Creative Commons Attribution-ShareAlike 2.5 License|]]|\n|''~CoreVersion:''|2.0.10|\n\nWhen many people share and edit copies of the same TiddlyWiki document, the ability to quickly collect all these changes back into a single, updated document that can then be redistributed to the entire group is very important. It can also be very extremely helpful when moving your own tiddlers from document to document (e.g., when upgrading to the latest version of TiddlyWiki, or 'pre-loading' your favorite stylesheets into a new 'empty' TiddlyWiki document.)\n\nThis plugin lets you selectively combine tiddlers from any two TiddlyWiki documents. An interactive control panel lets you pick a document to import from, and then select which tiddlers to import, with prompting for skip, rename, merge or replace actions when importing tiddlers that match existing titles. Automatically add tags to imported tiddlers so they are easy to find later on. Generates a detailed report of import 'history' in ImportedTiddlers.\n!!!!!Interactive interface\n<<<\n{{{<<importTiddlers>>}}}\ncreates "import tiddlers" link. click to show/hide import control panel\n\n{{{<<importTiddlers inline>>}}}\ncreates import control panel directly in tiddler content\n\n<<importTiddlers inline>>\n\nPress ''[browse]'' to select a TiddlyWiki document file to import. You can also type in the path/filename or a remote document URL (starting with http://)and press ''[open]''. //Note: There may be some delay to permit the browser time to access and load the document before updating the listbox with the titles of all tiddlers that are available to be imported.//\n\nSelect one or more titles from the listbox (hold CTRL or SHIFT while clicking to add/remove the highlight from individual list items). You can press ''[select all]'' to quickly highlight all tiddler titles in the list. Use the ''[-]'', ''[+]'', or ''[=]'' links to adjust the listbox size so you can view more (or less) tiddler titles at one time. When you have chosen the tiddlers you want to import and entered any extra tags, press ''[import]'' to begin copying them to the current TiddlyWiki document.\n\n''select: all, new, changes, or differences''\n\nYou can click on ''all'', ''new'', ''changes'', or ''differences'' to automatically select a subset of tiddlers from the list. This makes it very quick and easy to find and import just the updated tiddlers you are interested in:\n>''"all"'' selects ALL tiddlers from the import source document, even if they have not been changed.\n>''"new"'' selects only tiddlers that are found in the import source document, but do not yet exist in the destination document\n>''"changes"'' selects only tiddlers that exist in both documents but that are newer in the source document\n>''"differences"'' selects all new and existing tiddlers that are different from the destination document (even if destination tiddler is newer)\n\n''Import Tagging:''\n\nTiddlers that have been imported can be automatically tagged, so they will be easier to find later on, after they have been added to your document. New tags are entered into the "add tags" input field, and then //added// to the existing tags for each tiddler as it is imported.\n\n''Skip, Rename, Merge, or Replace:''\n\nWhen importing a tiddler whose title is identical to one that already exists, the import process pauses and the tiddler title is displayed in an input field, along with four push buttons: ''[skip]'', ''[rename]'', ''[merge]'' and ''[replace]''.\n\nTo bypass importing this tiddler, press ''[skip]''. To import the tiddler with a different name (so that both the tiddlers will exist when the import is done), enter a new title in the input field and then press ''[rename]''. Press ''[merge]'' to combine the content from both tiddlers into a single tiddler. Press ''[replace]'' to overwrite the existing tiddler with the imported one, discarding the previous tiddler content.\n\n//Note: if both the title ''and'' modification date/////time match, the imported tiddler is assumed to be identical to the existing one, and will be automatically skipped (i.e., not imported) without asking.//\n\n''Import Report History''\n\nWhen tiddlers are imported, a report is generated into ImportedTiddlers, indicating when the latest import was performed, the number of tiddlers successfully imported, from what location, and by whom. It also includes a list with the title, date and author of each tiddler that was imported.\n\nWhen the import process is completed, the ImportedTiddlers report is automatically displayed for your review. If more tiddlers are subsequently imported, a new report is //added// to ImportedTiddlers, above the previous report (i.e., at the top of the tiddler), so that a reverse-chronological history of imports is maintained.\n\nIf a cumulative record is not desired, the ImportedTiddlers report may be deleted at any time. A new ImportedTiddlers report will be created the next time tiddlers are imported.\n\nNote: You can prevent the ImportedTiddlers report from being generated for any given import activity by clearing the "create a report" checkbox before beginning the import processing.\n\n<<<\n!!!!!non-interactive 'load tiddlers' macro\n<<<\nUseful for automated installation/update of plugins and other tiddler content.\n\n{{{<<loadTiddlers "label:load tiddlers from %0" confirm>>}}}\n<<loadTiddlers "label:load tiddlers from %0" confirm>>\n\nSyntax:\n{{{<<loadTiddlers label:text prompt:text filter source quiet confirm>>}}}\n\n''label:text'' and ''prompt:text''\n>defines link text and tooltip (prompt) that can be clicked to trigger the load tiddler processing. If a label is NOT provided, then no link is created and loadTiddlers() is executed whenever the containing tiddler is rendered.\n''filter'' (optional) determines which tiddlers will be automatically selected for importing. Use one of the following keywords:\n>''"all"'' retrieves ALL tiddlers from the import source document, even if they have not been changed.\n>''"new"'' retrieves only tiddlers that are found in the import source document, but do not yet exist in the destination document\n>''"changes"'' retrieves only tiddlers that exist in both documents for which the import source tiddler is newer than the existing tiddler\n>''"updates"'' retrieves both ''new'' and ''changed'' tiddlers (this is the default action when none is specified)\n>''"tiddler:~TiddlerName"'' retrieves only the specific tiddler named in the parameter.\n>''"tag:text"'' retrieves only the tiddlers tagged with the indicated text.\n''source'' (required) is the location of the imported document. It can be either a local document path/filename in whatever format your system requires, or a remote web location (starting with "http://" or "https://")\n>use the keyword ''ask'' to prompt for a source location whenever the macro is invoked\n''"quiet"'' (optional)\n>supresses all status message during the import processing (e.g., "opening local file...", "found NN tiddlers..." etc). Note that if ANY tiddlers are actualy imported, a final information message will still be displayed (along with the ImportedTiddlers report), even when 'quiet' is specified. This ensures that changes to your document cannot occur without any visible indication at all.\n''"confirm"'' (optional)\n>adds interactive confirmation. A browser message box (OK/Cancel) is displayed for each tiddler that will be imported, so that you can manually bypass any tiddlers that you do not want to import.\n<<<\n!!!!!Installation\n<<<\ncopy/paste the following tiddlers into your document:\n''ImportTiddlersPlugin'' (tagged with <<tag systemConfig>>)\n\ncreate/edit ''SideBarOptions'': (sidebar menu items) \n^^Add "< < ImportTiddlers > >" macro^^\n\n''Quick Installation Tip #1:''\nIf you are using an unmodified version of TiddlyWiki (core release version <<version>>), you can get a new, empty TiddlyWiki with the Import Tiddlers plugin pre-installed (''[[download from here|TW+ImportExport.html]]''), and then simply import all your content from your old document into this new, empty document.\n<<<\n!!!!!Revision History\n<<<\n''2006.10.12 [3.0.8]'' in readTiddlersFromHTML(), fallback to find end of store area by matching "/body" when POST-BODY-START is not present (backward compatibility for older documents)\n''2006.09.10 [3.0.7]'' in readTiddlersFromHTML(), find end of store area by matching "POST-BODY-START" instead of "/body" \n''2006.08.16 [3.0.6]'' Use higher-level store.saveTiddler() instead of store.addTiddler() to avoid conflicts with ZW and other adaptations that hijack low-level tiddler handling. Also, in CreateImportPanel(), no longer register notify to "refresh listbox after every tiddler change" (left over from old 'auto-filtered' list handling). Thanks to Bob McElrath for report/solution.\n''2006.07.29 [3.0.5]'' added noChangeMsg to loadTiddlers processing. if not 'quiet' mode, reports skipped tiddlers.\n''2006.04.18 [3.0.4]'' in loadTiddlers.handler, fixed parsing of "prompt:" param. Also, corrected parameters mismatch in loadTiddlers() callback function definition (order of params was wrong, resulting in filters NOT being applied)\n''2006.04.12 [3.0.3]'' moved many display messages to macro properties for easier L10N translations via 'lingo' definitions.\n''2006.04.12 [3.0.2]'' additional refactoring of 'core candidate' code. Proposed API now defines "loadRemoteFile()" for XMLHttpRequest processing with built in fallback for handling local filesystem access, and readTiddlersFromHTML() to process the resulting source HTML content.\n''2006.04.04 [3.0.1]'' in refreshImportList(), when using [by tags], tiddlers without tags are now included in a new "untagged" psuedo-tag list section\n''2006.04.04 [3.0.0]'' Separate non-interactive {{{<<importTiddlers...>>}}} macro functionality for incorporation into TW2.1 core and renamed as {{{<<loadTiddlers>>}}} macro. New parameters for loadTiddlers: ''label:text'' and ''prompt:text'' for link creation, ''ask'' for filename/URL, ''tag:text'' for filtering, "confirm" for accept/reject of individual inbound tiddlers. Also, ImportedTiddlers report generator output has been simplified and "importReplace/importPublic" tags and associated "force" param (which were rarely, if ever, used) has been dropped.\n''2006.03.30 [2.9.1]'' when extracting store area from remote URL, look for "</body>" instead of "</body>\sn</html>" so it will match even if the "\sn" is absent from the source.\n''2006.03.30 [2.9.0]'' added optional 'force' macro param. When present, autoImportTiddlers() bypasses the checks for importPublic and importReplace. Based on a request from Tom Otvos.\n''2006.03.28 [2.8.1]'' in loadImportFile(), added checks to see if 'netscape' and 'x.overrideMimeType()' are defined (IE does *not* define these values, so we bypass this code)\nAlso, when extracting store area from remote URL, explicitly look for "</body>\sn</html>" to exclude any extra content that may have been added to the end of the file by hosting environments such as GeoCities. Thanks to Tom Otvos for finding these bugs and suggesting some fixes.\n''2006.02.21 [2.8.0]'' added support for "tiddler:TiddlerName" filtering parameter in auto-import processing\n''2006.02.21 [2.7.1]'' Clean up layout problems with IE. (Use tables for alignment instead of SPANs styled with float:left and float:right)\n''2006.02.21 [2.7.0]'' Added "local file" and "web server" radio buttons for selecting dynamic import source controls in ImportPanel. Default file control is replaced with URL text input field when "web server" is selected. Default remote document URL is defined in SiteURL tiddler. Also, added option for prepending SiteProxy URL as prefix to remote URL to mask cross-domain document access (requires compatible server-side script)\n''2006.02.17 [2.6.0]'' Removed "differences only" listbox display mode, replaced with selection filter 'presets': all/new/changes/differences. Also fixed initialization handling for "add new tags" so that checkbox state is correctly tracked when panel is first displayed.\n''2006.02.16 [2.5.4]'' added checkbox options to control "import remote tags" and "keep existing tags" behavior, in addition to existing "add new tags" functionality.\n''2006.02.14 [2.5.3]'' FF1501 corrected unintended global 't' (loop index) in importReport() and autoImportTiddlers()\n''2006.02.10 [2.5.2]'' corrected unintended global variable in importReport().\n''2006.02.05 [2.5.1]'' moved globals from window.* to config.macros.importTiddlers.* to avoid FireFox crash bug when referencing globals\n''2006.01.18 [2.5.0]'' added checkbox for "create a report". Default is to create/update the ImportedTiddlers report. Clear the checkbox to skip this step.\n''2006.01.15 [2.4.1]'' added "importPublic" tag and inverted default so that auto sharing is NOT done unless tagged with importPublic\n''2006.01.15 [2.4.0]'' Added support for tagging individual tiddlers with importSkip, importReplace, and/or importPrivate to control which tiddlers can be overwritten or shared with others when using auto-import macro syntax. Defaults are to SKIP overwriting existing tiddlers with imported tiddlers, and ALLOW your tiddlers to be auto-imported by others.\n''2006.01.15 [2.3.2]'' Added "ask" parameter to confirm each tiddler before importing (for use with auto-importing)\n''2006.01.15 [2.3.1]'' Strip TW core scripts from import source content and load just the storeArea into the hidden IFRAME. Makes loading more efficient by reducing the document size and by preventing the import document from executing its TW initialization (including plugins). Seems to resolve the "Found 0 tiddlers" problem. Also, when importing local documents, use convertUTF8ToUnicode() to convert the file contents so support international characters sets.\n''2006.01.12 [2.3.0]'' Reorganized code to use callback function for loading import files to support event-driven I/O via an ASYNCHRONOUS XMLHttpRequest. Let's processing continue while waiting for remote hosts to respond to URL requests. Added non-interactive 'batch' macro mode, using parameters to specify which tiddlers to import, and from what document source. Improved error messages and diagnostics, plus an optional 'quiet' switch for batch mode to eliminate //most// feedback.\n''2006.01.11 [2.2.0]'' Added "[by tags]" to list of tiddlers, based on code submitted by BradleyMeck\n''2006.01.09 [2.1.1]'' When a URL is typed in, and then the "open" button is pressed, it generates both an onChange event for the file input and a click event for open button. This results in multiple XMLHttpRequest()'s which seem to jam things up quite a bit. I removed the onChange handling for file input field. To open a file (local or URL), you must now explicitly press the "open" button in the control panel.\n''2006.01.08 [2.1.0]'' IMPORT FROM ANYWHERE!!! re-write getImportedTiddlers() logic to either read a local file (using local I/O), OR... read a remote file, using a combination of XML and an iframe to permit cross-domain reading of DOM elements. Adapted from example code and techniques courtesy of Jonny LeRoy.\n''2006.01.06 [2.0.2]'' When refreshing list contents, fixed check for tiddlerExists() when "show differences only" is selected, so that imported tiddlers that don't exist in the current file will be recognized as differences and included in the list.\n''2006.01.04 [2.0.1]'' When "show differences only" is NOT checked, import all tiddlers that have been selected even when they have a matching title and date.\n''2005.12.27 [2.0.0]'' Update for TW2.0\nDefer initial panel creation and only register a notification function when panel first is created\n''2005.12.22 [1.3.1]'' tweak formatting in importReport() and add 'discard report' link to output\n''2005.12.03 [1.3.0]'' Dynamically create/remove importPanel as needed to ensure only one instance of interface elements exists, even if there are multiple instances of macro embedding. Also, dynamically create/recreate importFrame each time an external TW document is loaded for importation (reduces DOM overhead and ensures a 'fresh' frame for each document)\n''2005.11.29 [1.2.1]'' fixed formatting of 'detail info' in importReport()\n''2005.11.11 [1.2.0]'' added 'inline' param to embed controls in a tiddler\n''2005.11.09 [1.1.0]'' only load HTML and CSS the first time the macro handler is called. Allows for redundant placement of the macro without creating multiple instances of controls with the same ID's.\n''2005.10.25 [1.0.5]'' fixed typo in importReport() that prevented reports from being generated\n''2005.10.09 [1.0.4]'' combined documentation with plugin code instead of using separate tiddlers\n''2005.08.05 [1.0.3]'' moved CSS and HTML definitions into plugin code instead of using separate tiddlers\n''2005.07.27 [1.0.2]'' core update 1.2.29: custom overlayStyleSheet() replaced with new core setStylesheet()\n''2005.07.23 [1.0.1]'' added parameter checks and corrected addNotification() usage\n''2005.07.20 [1.0.0]'' Initial Release\n<<<\n!!!!!Credits\n<<<\nThis feature was developed by EricShulman from [[ELS Design Studios|http:/]]\n<<<\n!!!!!Code\n***/\n// // ''MACRO DEFINITION''\n//{{{\n// Version\nversion.extensions.importTiddlers = {major: 3, minor: 0, revision: 8, date: new Date(2006,10,12)};\n\n// IE needs explicit global scoping for functions/vars called from browser events\nwindow.onClickImportButton=onClickImportButton;\nwindow.refreshImportList=refreshImportList;\n\n// default cookie/option values\nif (!config.options.chkImportReport) config.options.chkImportReport=true;\n\nconfig.macros.importTiddlers = { };\nconfig.macros.importTiddlers = {\n label: "import tiddlers",\n prompt: "Copy tiddlers from another document",\n foundMsg: "Found %0 tiddlers in %1",\n countMsg: "%0 tiddlers selected for import",\n importedMsg: "Imported %0 of %1 tiddlers from %2",\n src: "", // path/filename or URL of document to import (retrieved from SiteUrl tiddler)\n proxy: "", // URL for remote proxy script (retrieved from SiteProxy tiddler)\n useProxy: false, // use specific proxy script in front of remote URL\n inbound: null, // hash-indexed array of tiddlers from other document\n newTags: "", // text of tags added to imported tiddlers\n addTags: true, // add new tags to imported tiddlers\n listsize: 8, // # of lines to show in imported tiddler list\n importTags: true, // include tags from remote source document when importing a tiddler\n keepTags: true, // retain existing tags when replacing a tiddler\n index: 0, // current processing index in import list\n sort: "" // sort order for imported tiddler listbox\n};\n\nconfig.macros.importTiddlers.handler = function(place,macroName,params) {\n if (!config.macros.loadTiddlers.handler)\n { alert("importTiddlers error: this plugin requires LoadTiddlersPlugin or TiddlyWiki 2.1+"); return; }\n if (!params[0]) // LINK TO FLOATING PANEL\n createTiddlyButton(place,this.label,this.prompt,onClickImportMenu);\n else if (params[0]=="inline") {// // INLINE TIDDLER CONTENT\n createImportPanel(place);\n document.getElementById("importPanel").style.position="static";\n document.getElementById("importPanel").style.display="block";\n }\n else config.macros.loadTiddlers.handler(place,macroName,params); // FALLBACK: PASS TO LOADTIDDLERS\n}\n//}}}\n\n// // ''INTERFACE DEFINITION''\n\n// // Handle link click to create/show/hide control panel\n//{{{\nfunction onClickImportMenu(e)\n{\n if (!e) var e = window.event;\n var parent=resolveTarget(e).parentNode;\n var panel = document.getElementById("importPanel");\n if (panel==undefined || panel.parentNode!=parent)\n panel=createImportPanel(parent);\n var isOpen ="block";\n if(config.options.chkAnimate)\n anim.startAnimating(new Slider(panel,!isOpen,e.shiftKey || e.altKey,"none"));\n else\n = isOpen ?

Information Ecology is an evolving holistic life science
''Information Habitat: Where Information Lives'' - an ''NGO in Consultative Status with the United Nations Economic and Social Council'' - was founded in May 1990 in the context of preparations for the 1992 Earth Summit, held in Rio de Janeiro, Brazil. Information Habitat has focused on the transformative opportunties of information and communications technology (ICT) in support of broad-based participation of ~NGOs in the work of the United Nations, and the critical role of ICT in offering a path towards sustainable development.\n\nFor more information on Information Habitat, visit
''Information and Communications Sub-Committee'' of the [[NGO Committee on Education]]\n\n
''Information ecology'' is a holistic life science for a knowledge-based universe - and to the remarkable nature and properties of a knowledge-based universe, core concepts in information ecology - information ecosystem, information habitat, information species et al, the evolution of information in its present form, in the context of the global transition to an information age and broad-based participation and access to and exchange of information in the historic series of United Nations global conferences from the 1992 Earth Summit in Rio de Janeiro and the 1996 Habitat II conference in Istanbul and in the follow-up to these and related conferences.

/***\n|''Name:''|NestedSlidersPlugin|\n|''Source:''||\n|''Author:''|Eric Shulman - ELS Design Studios|\n|''License:''|[[Creative Commons Attribution-ShareAlike 2.5 License|]]|\n|''~CoreVersion:''|2.0.10|\n\nQuickly make any tiddler content into an expandable 'slider' panel, without needing to create a separate tiddler to contain the slider content. Optional syntax allows ''default to open'', ''custom button label/tooltip'' and ''automatic blockquote formatting.''\n\nYou can also 'nest' these sliders as deep as you like (see complex nesting example below), so that expandable 'tree-like' hierarchical displays can be created. This is most useful when converting existing in-line text content to create in-line annotations, footnotes, context-sensitive help, or other subordinate information displays.\n\nFor more details, please click on a section headline below:\n++++!!!!![Configuration]>\nDebugging messages for 'lazy sliders' deferred rendering:\n<<option chkDebugLazySliderDefer>> show debugging alert when deferring slider rendering\n<<option chkDebugLazySliderRender>> show debugging alert when deferred slider is actually rendered\n===\n++++!!!!![Usage]>\nWhen installed, this plugin adds new wiki syntax for embedding 'slider' panels directly into tiddler content. Use {{{+++}}} and {{{===}}} to delimit the slider content. Additional optional syntax elements let you specify\n*default to open\n*cookiename\n*heading level\n*floater (with optional CSS width value)\n*mouse auto rollover\n*custom class/label/tooltip/accesskey\n*automatic blockquote\n*deferred rendering\nThe complete syntax, using all options, is:\n//{{{\n++++(cookiename)!!!!!^width^*{{class{[label=key|tooltip]}}}>...\ncontent goes here\n===\n//}}}\nwhere:\n* {{{+++}}} (or {{{++++}}}) and {{{===}}}^^\nmarks the start and end of the slider definition, respectively. When the extra {{{+}}} is used, the slider will be open when initially displayed.^^\n* {{{(cookiename)}}}^^\nsaves the slider opened/closed state, and restores this state whenever the slider is re-rendered.^^\n* {{{!}}} through {{{!!!!!}}}^^\ndisplays the slider label using a formatted headline (Hn) style instead of a button/link style^^\n* {{{^width^}}} (or just {{{^}}})^^\nmakes the slider 'float' on top of other content rather than shifting that content downward. 'width' must be a valid CSS value (e.g., "30em", "180px", "50%", etc.). If omitted, the default width is "auto" (i.e., fit to content)^^\n* {{{*}}}^^\nautomatically opens/closes slider on "rollover" as well as when clicked^^\n* {{{{{class{[label=key|tooltip]}}}}}}^^\nuses custom label/tooltip/accesskey. {{{{{class{...}}}}}}, {{{=key}}} and {{{|tooltip}}} are optional. 'class' is any valid CSS class name, used to style the slider label text. 'key' must be a ''single letter only''. Default labels/tootips are: ">" (more) and "<" (less), with no default access key assignment.^^\n* {{{">"}}} //(without the quotes)//^^\nautomatically adds blockquote formatting to slider content^^\n* {{{"..."}}} //(without the quotes)//^^\ndefers rendering of closed sliders until the first time they are opened. //Note: deferred rendering may produce unexpected results in some cases. Use with care.//^^\n\n//Note: to make slider definitions easier to read and recognize when editing a tiddler, newlines immediately following the {{{+++}}} 'start slider' or preceding the {{{===}}} 'end slider' sequence are automatically supressed so that excess whitespace is eliminated from the output.//\n===\n++++!!!!![Examples]>\nsimple in-line slider: \n{{{\n+++\n content\n===\n}}}\n+++\n content\n===\n----\nuse a custom label and tooltip: \n{{{\n+++[label|tooltip]\n content\n===\n}}}\n+++[label|tooltip]\n content\n===\n----\ncontent automatically blockquoted: \n{{{\n+++>\n content\n===\n}}}\n+++>\n content\n===\n----\nall options combined //(default open, cookie, heading, sized floater, rollover, class, label/tooltip/key, blockquoted, deferred)//\n{{{\n++++(testcookie)!!!^30em^*{{big{[label=Z|click or press Alt-Z to open]}}}>...\n content\n===\n}}}\n++++(testcookie)!!!^30em^*{{big{[label=Z|click or press Alt-Z to open]}}}>...\n content\n===\n----\ncomplex nesting example:\n{{{\n+++^[get info...=I|click for information or press Alt-I]\n put some general information here, plus a floating slider with more specific info:\n +++^10em^[view details...|click for details]\n put some detail here, which could include a rollover with a +++^25em^*[glossary definition]explaining technical terms===\n ===\n===\n}}}\n+++^[get info...=I|click for information or press Alt-I]\n put some general information here, plus a floating slider with more specific info:\n +++^10em^[view details...|click for details]\n put some detail here, which could include a rollover with a +++^25em^*[glossary definition]explaining technical terms===\n ===\n===\n===\n!!!!!Installation\n<<<\nimport (or copy/paste) the following tiddlers into your document:\n''NestedSlidersPlugin'' (tagged with <<tag systemConfig>>)\n<<<\n!!!!!Revision History\n<<<\n''2006.07.28 - 2.0.0'' added custom class syntax around label/tip/key syntax: {{{{{classname{[label=key|tip]}}}}}}\n''2006.07.25 - 1.9.3'' when parsing slider, save default open/closed state in button element, then in onClickNestedSlider(), if slider state matches saved default, instead of saving cookie, delete it. Significantly reduces the 'cookie overhead' when default slider states are used.\n''2006.06.29 - 1.9.2'' in onClickNestedSlider(), when setting focus to first control, skip over type="hidden"\n''2006.06.22 - 1.9.1'' added panel.defaultPanelWidth to save requested panel width, even after resizing has changed the style value\n''2006.05.11 - 1.9.0'' added optional '^width^' syntax for floating sliders and '=key' syntax for setting an access key on a slider label\n''2006.05.09 - 1.8.0'' in onClickNestedSlider(), when showing panel, set focus to first child input/textarea/select element\n''2006.04.24 - 1.7.8'' in adjustSliderPos(), if floating panel is contained inside another floating panel, subtract offset of containing panel to find correct position\n''2006.02.16 - 1.7.7'' corrected deferred rendering to account for use-case where show/hide state is tracked in a cookie\n''2006.02.15 - 1.7.6'' in adjustSliderPos(), ensure that floating panel is positioned completely within the browser window (i.e., does not go beyond the right edge of the browser window)\n''2006.02.04 - 1.7.5'' add 'var' to unintended global variable declarations to avoid FireFox crash bug when assigning to globals\n''2006.01.18 - 1.7.4'' only define adjustSliderPos() function if it has not already been provided by another plugin. This lets other plugins 'hijack' the function even when they are loaded first.\n''2006.01.16 - 1.7.3'' added adjustSliderPos(place,btn,panel,panelClass) function to permit specialized logic for placement of floating panels. While it provides improved placement for many uses of floating panels, it exhibits a relative offset positioning error when used within *nested* floating panels. Short-term workaround is to only adjust the position for 'top-level' floaters.\n''2006.01.16 - 1.7.2'' added button property to slider panel elements so that slider panel can tell which button it belongs to. Also, re-activated and corrected animation handling so that nested sliders aren't clipped by hijacking Slider.prototype.stop so that "overflow:hidden" can be reset to "overflow:visible" after animation ends\n''2006.01.14 - 1.7.1'' added optional "^" syntax for floating panels. Defines new CSS class, ".floatingPanel", as an alternative for standard in-line ".sliderPanel" styles.\n''2006.01.14 - 1.7.0'' added optional "*" syntax for rollover handling to show/hide slider without requiring a click (Based on a suggestion by tw4efl)\n''2006.01.03 - 1.6.2'' When using optional "!" heading style, instead of creating a clickable "Hn" element, create an "A" element inside the "Hn" element. (allows click-through in SlideShowPlugin, which captures nearly all click events, except for hyperlinks)\n''2005.12.15 - 1.6.1'' added optional "..." syntax to invoke deferred ('lazy') rendering for initially hidden sliders\nremoved checkbox option for 'global' application of lazy sliders\n''2005.11.25 - 1.6.0'' added optional handling for 'lazy sliders' (deferred rendering for initially hidden sliders)\n''2005.11.21 - 1.5.1'' revised regular expressions: if present, a single newline //preceding// and/or //following// a slider definition will be suppressed so start/end syntax can be place on separate lines in the tiddler 'source' for improved readability. Similarly, any whitespace (newlines, tabs, spaces, etc.) trailing the 'start slider' syntax or preceding the 'end slider' syntax is also suppressed.\n''2005.11.20 - 1.5.0'' added (cookiename) syntax for optional tracking and restoring of slider open/close state\n''2005.11.11 - 1.4.0'' added !!!!! syntax to render slider label as a header (Hn) style instead of a button/link style\n''2005.11.07 - 1.3.0'' removed alternative syntax {{{(((}}} and {{{)))}}} (so they can be used by other\nformatting extensions) and simplified/improved regular expressions to trim multiple excess newlines\n''2005.11.05 - 1.2.1'' changed name to NestedSlidersPlugin\nmore documentation\n''2005.11.04 - 1.2.0'' added alternative character-mode syntax {{{(((}}} and {{{)))}}}\ntweaked "eat newlines" logic for line-mode {{{+++}}} and {{{===}}} syntax\n''2005.11.03 - 1.1.1'' fixed toggling of default tooltips ("more..." and "less...") when a non-default button label is used\ncode cleanup, added documentation\n''2005.11.03 - 1.1.0'' changed delimiter syntax from {{{(((}}} and {{{)))}}} to {{{+++}}} and {{{===}}}\nchanged name to EasySlidersPlugin\n''2005.11.03 - 1.0.0'' initial public release\n<<<\n!!!!!Credits\n<<<\nThis feature was implemented by EricShulman from [[ELS Design Studios|http:/]] with initial research and suggestions from RodneyGomes, GeoffSlocock, and PaulPetterson.\n<<<\n!!!!!Code\n***/\n//{{{\nversion.extensions.nestedSliders = {major: 2, minor: 0, revision: 0, date: new Date(2006,7,28)};\n//}}}\n\n//{{{\n// options for deferred rendering of sliders that are not initially displayed\nif (config.options.chkDebugLazySliderDefer==undefined) config.options.chkDebugLazySliderDefer=false;\nif (config.options.chkDebugLazySliderRender==undefined) config.options.chkDebugLazySliderRender=false;\n\n// default styles for 'floating' class\nsetStylesheet(".floatingPanel { position:absolute; z-index:10; padding:0.5em; margin:0em; \s\n background-color:#eee; color:#000; border:1px solid #000; text-align:left; }","floatingPanelStylesheet");\n//}}}\n\n//{{{\nconfig.formatters.push( {\n name: "nestedSliders",\n match: "\s\sn?\s\s+{3}",\n terminator: "\s\ss*\s\s={3}\s\sn?",\n lookahead: "\s\sn?\s\s+{3}(\s\s+)?(\s\s([^\s\s)]*\s\s))?(\s\s!*)?(\s\s^(?:[^\s\s^\s\s*\s\s[\s\s>]*\s\s^)?)?(\s\s*)?(?:\s\s{\s\s{([\s\sw]+[\s\ss\s\sw]*)\s\s{)?(\s\s[[^\s\s]]*\s\s])?(?:\s\s}{3})?(\s\s>)?(\s\s.\s\s.\s\s.)?\s\ss*",\n handler: function(w)\n {\n // defopen=lookaheadMatch[1]\n // cookiename=lookaheadMatch[2]\n // header=lookaheadMatch[3]\n // panelwidth=lookaheadMatch[4]\n // rollover=lookaheadMatch[5]\n // class=lookaheadMatch[6]\n // label=lookaheadMatch[7]\n // blockquote=lookaheadMatch[8]\n // deferred=lookaheadMatch[9]\n\n lookaheadRegExp = new RegExp(this.lookahead,"mg");\n lookaheadRegExp.lastIndex = w.matchStart;\n var lookaheadMatch = lookaheadRegExp.exec(w.source)\n if(lookaheadMatch && lookaheadMatch.index == w.matchStart)\n {\n // location for rendering button and panel\n var place=w.output;\n\n // default to closed, no cookie, no accesskey\n var show="none"; var title=">"; var tooltip="show"; var cookie=""; var key="";\n\n // extra "+", default to open\n if (lookaheadMatch[1])\n { show="block"; title="<"; tooltip="hide"; }\n\n // cookie, use saved open/closed state\
