  • Marvin Harris on India’s Sacred Cow

    News photographs that came out of India during the famine of the late 1960s showed starving people stretching out bony hands to beg for food while cattle strolled behind them undisturbed. The Hindu, it seems, would rather starve to death than eat his cow or even deprive it of food.

    Western specialists in food habits around the world consider Hinduism an irrational ideology that compels people to overlook abundant, nutritious foods for scarcer, less healthful foods. Many Western observers believe that an absurd devotion to the mother cow pervades Indian life. Many Indians agree with Western assessments of the Hindu reverence for their cattle, the zebu, a large-humped species of cattle prevalent in Asia and Africa. M. N. Srinivas, an Indian anthropologist states:

    “Orthodox Hindu opinion regards the killing of cattle with abhorrence, even though the refusal to kill the vast number of useless cattle which exists in India today is detrimental to the nation.” Even the Indian Ministry of Information formerly maintained that “the large animal population is more a liability than an asset in view of our land resources.”

    Accounts from many different sources point to the same conclusion: India, one of the world’s great civilizations, is being strangled by its love for the cow.

    The easy explanation for India’s devotion to the cow, the one most Westerners and Indians would offer, is that cow worship is an integral part of Hinduism. Religion is somehow good for the soul, even if it sometimes fails the body. Religion orders the cosmos and explains our place in the universe. Religious beliefs, many would claim, have existed for thousands of years and have a life of their own. They are not understandable in scientific terms. But all this ignores history. There is more to be said for cow worship than is immediately apparent.

    History of Cow Worship

    The earliest Vedas, the Hindu sacred texts from the Second Millennium B.C., do not prohibit the slaughter of cattle. Instead, they ordain it as a part of sacrificial rites. The early Hindus did not avoid the flesh of cows and bulls; they ate it at ceremonial feasts presided over by Brahman priests.

    Cow worship is a relatively recent development in India; it evolved as the Hindu religion developed and changed. This evolution is recorded in royal edicts and religious texts written during the last 3,000 years of Indian history. The Vedas from the First Millennium B.C. contain contradictory passages, some referring to ritual slaughter and others to a strict taboo on beef consumption. Many of the sacred-cow passages were incorporated into the texts by priests in a later period.

    By 200 A.D. the status of Indian cattle had undergone a transformation. The Brahman priesthood exhorted the population to venerate the cow and forbade them to abuse it or to feed on it. Religious feasts involving the ritual slaughter and consumption of livestock were eliminated and meat eating was restricted to the nobility.

    By 1000 A.D., all Hindus were forbidden to eat beef. Ahimsa, the Hindu belief in the unity of all life, was the spiritual justification for this restriction. But it is difficult to ascertain exactly when this change occurred. An important event that helped to shape the modern complex was the Islamic invasion, which took place in the Eighth Century A.D. Hindus may have found it politically expedient to set themselves off from the invaders, who were beefeaters, by emphasizing the need to prevent the slaughter of their sacred animals. Thereafter, the cow taboo assumed its modern form and began to function much as it does today. The place of the cow in modern India is every place – on posters, in the movies, in brass figures, in stone and wood carvings, on the streets, in the fields. The cow is a symbol of health and abundance.

    The Economic Uses of The Cow

    The cattle are not just worshiped and revered in India. They are also extraordinarily useful.

    The zebu cow provides the milk that Indians consume in the form of yogurt and ghee (clarified butter), which contribute subtle flavors to much spicy Indian food. This is one practical role of the cow, but cows provide less than half the milk produced in India. Most cows in India are not dairy breeds. In most regions, when an Indian farmer wants a steady, high-quality source of milk he usually invests in a female water buffalo. In India the water buffalo is the specialized dairy breed because its milk has a higher butterfat content than zebu milk. Although the farmer milks his zebu cows, the milk is merely a by-product. More vital than zebu milk to South Asian farmers are zebu calves. Male calves are especially valued because from bulls come oxen which are the mainstay of the Indian agricultural system.

    Small, fast oxen drag wooden plows through late-spring fields when monsoons have dampened the dry, cracked earth. After harvest, the oxen break the grain from the stalk by stomping through mounds of cut wheat and rice. For rice cultivation in irrigated fields, the male water buffalo is preferred (it pulls better in deep mud), but for most other crops, including rainfall rice, wheat, sorghum, and millet, and for transporting goods and people to and from town, a team of oxen is preferred.

    The ox is the Indian peasant’s tractor, thresher and family car combined; the cow is the factory that produces the ox.

    If draft animals instead of cows are counted, India appears to have too few domesticated ruminants, not too many. Since each of the 70 million farms in India requires a draft team, it follows that Indian peasants should use 140 million animals in the fields. But there are only 83 million oxen and male water buffalo on the subcontinent, a shortage of 30 million draft teams. In other regions of the world, joint ownership of draft animals might overcome a shortage, but Indian agriculture is closely tied to the monsoon rains of late spring and summer. Field preparation and planting must coincide with the rain, and a farmer must have his animals ready to plow when the weather is right. When the farmer without a draft team needs bullocks most, his neighbors are all using theirs. Any delay in turning the soil drastically lowers production.

    Because of this dependence on draft animals, loss of the family oxen is devastating. If a beast dies, the farmer must borrow money to buy or rent an ox at interest rates so high that he ultimately loses his land. Every year foreclosures force thousands of poverty-stricken peasants to abandon the countryside for the overcrowded cities.

    If a family is fortunate enough to own a fertile cow, it will be able to rear replacements for a lost team and thus survive until life returns to normal. If, as sometimes happens, famine leads a family to sell its cow and ox team, all ties to agriculture are cut. Even if the family survives, it has no way to farm the land, no oxen to work the land, and no cows to produce oxen. The prohibition against eating meat applies to the flesh of cows, bulls, and oxen, but the cow is the most sacred because it can produce the other two. The peasant whose cow dies is not only crying over a spiritual loss but over the loss of his farm as well.

    Religious laws that forbid the slaughter of cattle promote the recovery of the agricultural system from the dry Indian winter and from periods of drought. The monsoon, on which all agriculture depends, is erratic. Sometimes it arrives early, sometimes late, sometimes not at all. Drought has struck large portions of India time and again in this century, and Indian farmers and the zebus are accustomed to these natural disasters. Zebus can pass weeks on end with little or no food and water. Like camels, they store both in their humps and recuperate quickly with only a little nourishment.

    During droughts the cows often stop lactating and become barren. In some cases the condition is permanent but often it is only temporary. If barren animals were summarily eliminated, as Western experts in animal husbandry have suggested, cows capable of recovery would be lost along with those entirely debilitated. By keeping alive the cows that can later produce oxen, religious laws against cow slaughter assure the recovery of the agricultural system from the greatest challenge it faces – the failure of the monsoon.

    The local Indian governments aid the process of recovery by maintaining homes for barren cows. Farmers reclaim any animal that calves or begins to lactate. One police station in Madras collects strays and pastures them in a field adjacent to the station. After a small fine is paid, a cow is returned to its rightful owner when the owner thinks the cow shows signs of being able to reproduce.

    During the hot, dry spring months most of India is like a desert. Indian farmers often complain they cannot feed their livestock during this period. They maintain cattle by letting them scavenge on the sparse grass along the roads. In the cities cattle are encouraged to scavenge near food stalls to supplement their scant diet. These are the wandering cattle tourists report seeing throughout India.

    Westerners expect shopkeepers to respond to these intrusions with the deference due a sacred animal; instead, their response is a string of curses and the crack of a long bamboo pole across the beast’s back or a poke at its genitals. Mahatma Gandhi was well aware of the treatment sacred cows (and bulls and oxen) received in India:

    “How we bleed her to take the last drop of milk from her. How we starve her to emaciation, how we ill-treat the calves, how we deprive them of their portion of milk, how cruelly we treat the oxen, how we castrate them, how we beat them, how we overload them.”

    Oxen generally receive better treatment than cows. When food is in short supply, thrifty Indian peasants feed their working bullocks and ignore their cows, but rarely do they abandon the cows to die. When cows are sick, farmers worry over them as they would over members of the family and nurse them as if they were children. When the rains return and when the fields are harvested, the farmers again feed their cows regularly and reclaim their abandoned animals. The prohibition against beef consumption is a form of disaster insurance for all India.

    Western agronomists and economists are quick to protest that the functions of the zebu cattle can be improved with organized breeding programs, cultivated pastures, and silage. Because stronger oxen would pull the plow faster, they could work multiple plots of land, allowing farmers to share their animals. Fewer healthy, well-fed cows could provide Indians with more milk. But pastures and silage require arable land, land needed to produce wheat and rice.

    A look at Western cattle farming makes plain the cost of adopting advanced technology in Indian agriculture. In a study of livestock production in the United States, one scientist at Cornell University found that 91 percent of the cereal, legume, and vegetable protein suitable for human consumption is consumed by livestock. Approximately three quarters of the arable land in the United States is devoted to growing food for livestock. In the production of meat and milk, American ranchers use enough fossil fuel to equal more than 82 million barrels of oil annually. Indian cattle do not drain the system in the same way. In a 1971 study of livestock in West Bengal, India, by a professor at the University of Missouri, found that Bengalese cattle ate only the inedible remains of subsistence crops – rice straw, rice hulls, the tops of sugar cane, and mustard-oil cake. Cattle graze in the fields after harvest and eat the remains of crops left on the ground; they forage for grass and weeds on the roadsides. The food for zebu cattle costs the human population virtually nothing. “Basically the cattle convert items of little direct human value into products of immediate utility.”

    In addition to plowing the fields and producing milk, the zebus produce dung, which fires the hearths and fertilizes the fields of India. Much of the estimated 800 million tons of manure produced annually is collected by the farmers’ children as they follow the family cows and bullocks from place to place. And when the children see the droppings of another farmer’s cattle along the road, they pick those up also. The system operates with such high efficiency that the children of West Bengal recover nearly 100 percent of the dung produced by their livestock.

    From 40 to 70 percent of all manure produced by Indian cattle is used as fuel for cooking; the rest is returned to the fields as fertilizer. Dried dung burns slowly, cleanly, and with low heat – characteristics that satisfy the household needs of Indian women. Staples like curry and rice can simmer for hours. While the meal slowly cooks over an unattended fire, the women of the household can do other chores. Cow chips, unlike firewood, do not scorch as they burn. It is estimated that the dung used for cooking fuel provides the energy-equivalent of 43 million tons of coal. At current prices, it would cost India an extra 1.5 billion dollars in foreign exchange to replace the dung with coal. And if the 350 million tons of manure that are being used as fertilizer were replaced with commercial fertilizers, the expense would be even greater. Roger Revelle of the University of California at San Diego has calculated that 89 percent of the energy used in Indian agriculture, the equivalent of about 140 million tons of coal, is provided by local sources. Even if foreign loans were to provide the money, the capital outlay necessary to replace the Indian cow with tractors and fertilizers for the fields, coal for the fires, and transportation for the family would probably warp international financial institutions for years.

    Instead of asking the Indians to learn from the American model of industrial agriculture, American farmers might learn energy conservation from the Indians. Every step in an energy cycle results in a loss of energy to the system. Like a pendulum that slows a bit with each swing, each transfer of energy from sun to plants, plants to animals, and animals to human beings involves energy losses. Some systems are more efficent than others; they provide a higher percentage of the energy inputs in a final, useful form. Seventeen percent of all energy zebus consume is returned in the form of milk, traction and dung. American cattle raised on Western range land return only 4 percent of the energy they consume.

    But the American system is improving. Based on techniques pioneered by Indian scientists, at least one commercial firm in the United States is reported to be building plants that will turn manure from cattle feedlots into combustible gas. When organic matter is broken down by anaerobic bacteria, methane gas and carbon dioxide are produced. After the methane is cleansed of the carbon dioxide, it is available for the same purposes as natural gas – cooking, heating, electricity generation. The company constructing the plant plans to sell its product to a gas-supply company, to be piped through the existing distribution system. Schemes similar to this one could make cattle ranches almost independent of utility and gasoline companies, for methane can be used to run trucks, tractors, and cars as well as to supply heat and electricity. The relative energy self-sufficiency that the Indian peasant has achieved is a goal American farmers and industry are now striving for.

    Studies often understate the efficiency of the Indian cow, because dead cows are used for purposes that Hindus prefer not to acknowledge. When a cow dies, an Untouchable, a member of one of the lowest ranking castes in India, is summoned to haul away the carcass. Higher castes consider the body of the dead cow polluting; if they do handle it, they must go through a rite of purification.

    Untouchables first skin the dead animal and either tan the skin themselves or sell it to a leather factory. In the privacy of their homes, contrary to the teachings of Hinduism, untouchable castes cook the meat and eat it. Indians of all castes rarely acknowledge the existence of these practices to non-Hindus, but most are aware that beef eating takes place. The prohibition against beef eating restricts consumption by the higher castes and helps distribute animal protein to the poorest sectors of the population that otherwise would have no source of these vital nutrients.

    Untouchables are not the only Indians who consume beef. Indian Muslims and Christians are under no restriction that forbids them beef, and its consumption is legal in many places. The Indian ban on cow slaughter is state, not national, law and not all states restrict it. In many cities, such as New Delhi, Calcutta, and Bombay, legal slaughterhouses sell beef to retail customers and to the restaurants that serve steak.

    If the caloric value of beef and the energy costs involved in the manufacture of synthetic leather were included in the estimates of energy, the calculated efficiency of Indian livestock would rise considerably.

    As well as the system works, experts often claim that its efficiency can be further improved. An economist at the University of Pennsylvania, believes that Indians suffer from an overabundance of cows simply because they refuse to slaughter the excess cattle. India could produce at least the same number of oxen and the same quantities of milk and manure with 30 million fewer cows. The economist calculates that only 40 cows are necessary to maintain a population of 100 bulls and oxen. Since India averages 70 cows for every 100 bullocks, the difference, 30 million cows, is expendable.

    What this economist fails to note is that sex ratios among cattle in different regions of India vary tremendously, indicating that adjustments in the cow population do take place. Along the Ganges River, one of the holiest shrines of Hinduism, the ratio drops to 47 cows for every 100 male animals. This ratio reflects the preference for dairy buffalo for farming. In nearby Pakistan, in contrast, where cow slaughter is permitted, the sex ratio is 60 cows to 100 oxen. Since the sex ratios among cattle differ greatly from region to region and do not even approximate the balance that would be expected if no females were killed, we can assume that some culling of herds does take place; Indians do adjust their religious restrictions to accommodate ecological realities.

    They cannot kill a cow but they can tether an old or unhealthy animal until it has starved to death. They cannot slaughter a calf but they can yoke it with a large wooden triangle so that when it nurses it irritates the mother’s udder and gets kicked to death. They cannot ship their animals to the slaughterhouse but they can sell them to Muslims, closing their eyes to the fact that the Muslims will take the cattle to the slaughterhouse. These violations of the prohibition against cattle slaughter strengthen the premise that cow worship is a vital part of Indian economic life and culture.

    The Historical Context of the Taboo on Eating Beef

    The religious ban on killing cattle and eating beef arose to prevent the population from consuming the animal on which Indian agriculture depends. During the First Millennium B.C., the Ganges Valley became one of the most densely populated regions of the world. Where previously there had been only scattered villages, many towns and cities arose and peasants farmed every available acre of land. Kingsley Davis, a population expert at the University of California at Berkeley, estimates that by 300 B.C. between 50 million and 100 million people were living in India. The forested Ganges Valley became a windswept semi-desert and signs of ecological collapse appeared; droughts and floods became commonplace, erosion took away the rich topsoil, farms shrank as population increased, and domesticated animals became harder and harder to maintain.

    It is probable that the elimination of meat eating came about in a slow, practical manner. The farmers who decided not to eat their cows, who saved them for procreation to produce oxen, were the ones who survived the natural disasters. Those who ate beef lost the tools with which to farm. Over a period of centuries, more and more farmers probably avoided beef until an unwritten taboo came into existence.

    Only later was the practice codified by the priesthood. While Indian peasants were probably aware of the role of cattle in their society, strong sanctions were necessary to protect zebus from a population faced with starvation. To remove temptation, the flesh of cattle became taboo and the cow became sacred.

    The sacredness of the cow is not just an ignorant belief that stands in the way of progress. Like all concepts of the sacred and the profane, this one affects the physical world; it defines the relationships that are important for the maintenance of Indian society.

    Indians have the sacred cow; we have the “sacred” car and the “sacred” dog. It would not occur to us to propose the elimination of automobiles and dogs from our society without carefully considering the consequences, and we should not propose the elimination of zebu cattle without first understanding their place in the social order in India.

    Human society is neither random nor capricious. The regularities of thought and behavior called culture are the principal mechanisms by which we human beings adapt to the world around us. Practices and beliefs can be rational or irrational, but a society that fails to adapt to its environment is doomed to extinction. Only those societies that draw the necessities of life from their surroundings without destroying those surroundings, inherit the earth. The West has much to learn from the great antiquity of Indian civilization, and the sacred cow is an important part of that lesson.

     

  • Brown coal companies attempt emissions blackmail

    It was a drastic statement. The Latrobe Valley provides more than 90% of Victoria’s power and if Mr McIndoe is right, the state would grind to a halt. Most observers believed the comments were just part of the industry’s frantic lobbying at this crucial time: the Federal Government, following Professor Ross Garnaut’s draft report on Friday, is finalising the details of its carbon scheme, while Climate Change Minister Penny Wong is set to release a green paper next week.

    But Mr McIndoe’s warning hints at how much pressure a carbon price will place on Victoria, the state most reliant on dirty brown coal. Although careful to respect the Federal Government’s process, Victorian Energy Minister Peter Batchelor appears increasingly nervous in his public comments. Asked if one of the state’s brown coal generators will be forced to close prematurely, he said: “It depends on the nature of the emissions trading scheme (introduced).”

    Under a trading scheme, large polluting companies such as power stations must buy from the Government an ever-decreasing amount of permits to emit carbon dioxide. This cost is passed on to the customer with the idea that carbon-heavy goods and services become more expensive and are used less. In the meantime, if companies find cleaner ways to produce energy and fuel, they benefit from not having to buy permits or from selling them to others.

    The scheme will push some of Victoria’s brown coal generators to the wall – even industry accepts that. The questions are when and which ones go first.

    Meanwhile, the spin on clean coal is wearing thin. Despite millions of dollars of taxpayer investment, the costs of retrofitting Victoria’s four brown coal power stations with technology to make them cleaner could be so high it might be cheaper to build new ones or convert them to natural gas.

    Safely putting carbon back in the ground, a process known as geosequestration, has been widely seen as the biggest test for clean coal technology. But a bigger test for the power stations is actually how to capture the carbon from generators before it is buried.

    The size of the infrastructure to capture carbon is enormous and any full retrofit could see a generator out of service for years. While the scientists say it is technically possible, none of the three companies that own brown coal plants have declared it likely to be economically viable.

    “The companies would never do it, it would send them broke,” says John Boshier, the executive director of the National Generators Forum, which represents the Latrobe Valley brown coal power plants of Hazelwood, Yallourn, Loy Yang A and Loy Yang B. “I’m an engineer and I can’t see how it can be done, but someone might figure out how to do it.”

    Energy Minister Peter Batchelor acknowledges the difficulties, but stands by the $30 million investment in clean coal technology trials designed for retrofitting the 44-year-old Hazelwood plant, the state’s oldest. “There’s no doubt about it – retro-fitting existing power plants is both a difficult and expensive task. But we’ve got to try everything. There’s no silver bullet,” he said.

    Last week, the Brumby Government trumpeted a new brown coal plant for Victoria, just three days before the release of Professor Garnaut’s draft report. In his press release, Mr Batchelor said the $750 million Latrobe Valley development, to be built by HRL and Chinese power company Harbin, was a “clean coal” power station – it is 30% better than a normal brown coal plant, but just as polluting as NSW’s black coal plant.

    But based on figures provided by the State Government to The Sunday Age, a rough calculation shows that the plant will emit 72 million tonnes of carbon dioxide over its 30-year life. This would almost negate the expected annual pollution savings of the Victorian Energy Efficiency Scheme, designed to cut energy use in homes by 10% by 2010.

    The Victorian announcement caused grumblings of displeasure around the offices of the Garnaut Review, but the professor himself is not too concerned. The reason is that the new coal-fired power station will be able to substitute gas for coal, thereby reducing its emissions, and will be designed to take on capture and storage technology when it becomes economically feasible. “It is appropriate that coal-based power generation be prepared for capture of carbon dioxide as soon as possible,” he told The Sunday Age yesterday.

    If emissions trading comes in at 2010, as planned, and clean coal is not considered viable until 2020 or 2025, Victoria’s brown coal generators face an uncertain 10 years.

    Brown coal electricity produces more carbon than any other fossil fuel because it has a high water content and is inefficient to burn. Until now it has been one of the cheapest ways to make electricity and this bargain power has underpinned the state’s manufacturing sector. But because it produces more carbon, the companies that own the generators – TRUenergy, International Power and AGL – must, under the emissions trading scheme, buy more permits, which pushes up their costs. Most of this cost will be passed on to consumers on their electricity bills.

    Even if the Government initially sets a low price, between $20 to $30 a tonne of carbon is mooted, brown coal electricity starts to become uncompetitive with black coal, which can be imported on the national electricity market from NSW. Also, at low carbon prices, brown coal starts to become more expensive than gas. Natural gas, a much cleaner fossil fuel, has generally been used in Victoria to cover peak demand. But a carbon price would push these gas plants into full production.

    As the carbon price rises to between $30 and $40 generators may shut down some parts of their plant and cut back on maintenance, further stressing the bottom line. At this point one of Victoria’s two dirtiest power stations – Hazelwood and Yallourn – could be pushed to their economic limit. “There is no doubt the older plants are less able to be retrofitted and adjust to a world where they have to ramp up and down,” says Paul Johnston, CommSec senior utilities analyst.

    When the carbon price hits $50 to $60, renewable energy such as wind will start to become competitive and the clean coal technologies appear more attractive. It may also become economic at this point to start replacing coal with gas entirely.

    There is an upside for brown coal, however. As it is traded on the international market, gas prices are likely to rise sharply at some stage – meaning that, for a time, the remaining brown coal stations will be on an even keel price-wise with natural gas.

     

    Then, as the Federal Government further restricts pollution permits, the carbon price is expected to rise again, making expensive energy sources, such as big solar thermal plants, more economical. But it is difficult to estimate the timing of these carbon price levels without knowing how quickly the Government will want to cut greenhouse gases and how the carbon price and the energy market will react over decades.

    For his part, Professor Garnaut believes the generators’ modelling that predicts early shut-downs is flawed. He told The Sunday Age yesterday that the companies, at least in the early stages of carbon trading, were in a reasonable position because of the rising costs of their gas and black coal competitors. The costs of building new power stations were rising so quickly that retrofitting would become more commercially viable, he said.

    In his report, Professor Garnaut said $1 billion to $2 billion of the emissions trading scheme proceeds should be invested in clean coal technologies, matched dollar for dollar by the companies. If clean coal worked, he said, the Latrobe Valley would heave a “prosperous and expansive future”. If it didn’t, money from the scheme should be used to help retrain workers and to help the valley community survive the brave new world of zero emissions.

     

  • World Bank blames biofuels for food prices

    “It would put the World Bank in a political hot-spot with the White House,” said one yesterday.

    The news comes at a critical point in the world’s negotiations on biofuels policy. Leaders of the G8 industrialised countries meet next week in Hokkaido, Japan, where they will discuss the food crisis and come under intense lobbying from campaigners calling for a moratorium on the use of plant-derived fuels.

    It will also put pressure on the British government, which is due to release its own report on the impact of biofuels, the Gallagher Report. The Guardian has previously reported that the British study will state that plant fuels have played a “significant” part in pushing up food prices to record levels. Although it was expected last week, the report has still not been released.

    “Political leaders seem intent on suppressing and ignoring the strong evidence that biofuels are a major factor in recent food price rises,” said Robert Bailey, policy adviser at Oxfam. “It is imperative that we have the full picture. While politicians concentrate on keeping industry lobbies happy, people in poor countries cannot afford enough to eat.”

    Rising food prices have pushed 100m people worldwide below the poverty line, estimates the World Bank, and have sparked riots from Bangladesh to Egypt. Government ministers here have described higher food and fuel prices as “the first real economic crisis of globalisation”.

    President Bush has linked higher food prices to higher demand from India and China, but the leaked World Bank study disputes that: “Rapid income growth in developing countries has not led to large increases in global grain consumption and was not a major factor responsible for the large price increases.”

    Even successive droughts in Australia, calculates the report, have had a marginal impact. Instead, it argues that the EU and US drive for biofuels has had by far the biggest impact on food supply and prices.

    Since April, all petrol and diesel in Britain has had to include 2.5% from biofuels. The EU has been considering raising that target to 10% by 2020, but is faced with mounting evidence that that will only push food prices higher.

    “Without the increase in biofuels, global wheat and maize stocks would not have declined appreciably and price increases due to other factors would have been moderate,” says the report. The basket of food prices examined in the study rose by 140% between 2002 and this February. The report estimates that higher energy and fertiliser prices accounted for an increase of only 15%, while biofuels have been responsible for a 75% jump over that period.

    It argues that production of biofuels has distorted food markets in three main ways. First, it has diverted grain away from food for fuel, with over a third of US corn now used to produce ethanol and about half of vegetable oils in the EU going towards the production of biodiesel. Second, farmers have been encouraged to set land aside for biofuel production. Third, it has sparked financial speculation in grains, driving prices up higher.

    Other reviews of the food crisis looked at it over a much longer period, or have not linked these three factors, and so arrived at smaller estimates of the impact from biofuels. But the report author, Don Mitchell, is a senior economist at the Bank and has done a detailed, month-by-month analysis of the surge in food prices, which allows much closer examination of the link between biofuels and food supply.

    The report points out biofuels derived from sugarcane, which Brazil specializes in, have not had such a dramatic impact.

    Supporters of biofuels argue that they are a greener alternative to relying on oil and other fossil fuels, but even that claim has been disputed by some experts, who argue that it does not apply to US production of ethanol from plants.

    “It is clear that some biofuels have huge impacts on food prices,” said Dr David King, the government’s former chief scientific adviser, last night. “All we are doing by supporting these is subsidising higher food prices, while doing nothing to tackle climate change.”

  • Poor farmland offers biofuel solution

    Elliot Campbell, Robert Genova and Christopher Field of the Carnegie Institution’s Department of Global Ecology, with David Lobell of Stanford University, estimated the global extent of abandoned crop and pastureland and calculated their potential for sustainable bioenergy production from historical land-use data, satellite imaging and ecosystem models. Agricultural areas that have been converted to urban areas or have reverted to forests were not included in the assessment. 

    The researchers estimate that globally up to 4.7 million square kilometers (approximately 1.8 million square miles) of abandoned lands could be available for growing energy crops. The potential yield of this land area, equivalent to nearly half the land area of the United States (including Alaska), depends on local soils and climate, as well as on the specific energy crops and cultivation methods in each region. But the researchers estimate that the worldwide harvestable dry biomass could amount to as much as 2.1 billion tons, with a total energy content of about 41 exajoules. While this is a significant amount of energy (one exajoule is a billion billion joules, equivalent to about 170 million barrels of oil), at best it would satisfy only about 8% of worldwide energy demand.

    “At the national scale, the bioenergy potential is largest in the United States, Brazil and Australia,” says lead author Campbell. “These countries have the most extensive areas of abandoned crop and pasture lands. Eastern North America has the largest area of abandoned croplands, and the Midwest has the biggest expanse of abandoned pastureland. Even so, if 100% of these lands were used for bioenergy, they would still only yield enough for about 6% of our national energy needs.”

    The study revealed larger opportunities in other parts of the world. In some African countries, where grassland ecosystems are very productive and current fossil fuel demand is low, biomass could provide up to 37 times the energy currently used.

    “Our study shows that there is clearly a potential for developing sustainable bioenergy, and we’ve been able to identify areas where biomass can be grown for energy, without endangering food security or making climate change worse,” says Field, director of the Department of Global Ecology. “But we can’t count on bioenergy to be a dominant contributor to the global energy system over the next few decades. Expanding beyond its sustainable limits would threaten food security and have serious environmental impacts.”

    This research was funded by the Carnegie Institution and by the Global Climate and Energy Project at Stanford University.

  • The fat of the land

    The incredible shrinking Dad observed through a teaspoon of shredded lettuce that it is impossible to get fat if you don’t stick it in your face. I forced away dreams of deep fried potatoes and reminisced about the surfing lessons I gave myself for my fortieth birthday. A dozen, slender, twenty-somethings and one fat old bastard lined up on Belongil Beach. Four hours later, they were complaining about sore calf muscles from balancing on the board. My calf muscles were as good as new. It was my upper arms that caned from trying to haul my fat carcass to the vertical.

    It shocked me enough to stop drinking the left over gravy and start running. Exercise is more fun than starvation, in my book.

    A dietician friend is hired by the mining companies to help keep their workforce healthy. The catering at the mine is four star and sometimes, the miners go a little silly. Interviewing one fair sized fella, she asked if he ate meat more than once a day. Detecting a certain shiftiness in his response, she probed. He had eaten four steaks for breakfast, every day for a week. We never got to talk about his dinner.

    At the turn of last century over seventy five percent of the energy spent doing useful work in the United States was provided by animals or humans. Muscle power dug the ditches, ploughed the fields and pulled the carriages that drove civilisation.

    Come the year 2000 and muscle power contributes a fraction of one percent. Machines clean our floors and dishes, knead our bread and carry us around the corner to pick up “stuff” we can’t be bothered making. Sixty percent of car trips in Australian cities are shorter than fifteen minutes. Elbow grease now comes out of a spray can.

    The modern tractor, or excavator, is air-conditioned and laser-guided with a CD player on the dash. The notion of a working man, and his shape, is so far removed from that of a century ago as to be completely alien. Pop-Eye was once your average Joe.

    I’m not suggesting that we turn off machines altogether, though oil prices may force us to, but it does seem odd to spend money on machines that save us making any effort and then spend more money in the gym on another machine to exercise our wasted muscles.

    One story that did not make the papers is that Haitians are suffering kidney failure from the mud-cakes they eat to quell their hunger pangs.

    They mix a special yellow clay with salt and fat – no worshipers of Pritikin, these folk – bake them in patty cake tins and take them to market. Traditionally the cakes delivered calcium to pregnant mums but have become a staple food since the grain ran out. Not all of the minerals in these mud cakes are good for you, thus the kidney failure.

    If it wasn’t for the food miles involved we could trade hamburgers for mud-pies and solve two problems at the same time.

  • Let’s celebrate independence

    Breakfast radio can be lonely. It’s dark when you unlock the studio, print out the weather and start talking to an audience, who is, mostly, still in bed.

    No doubt many of you accidentally or deliberately celebrated the overthrow of British imperialism by a militia of American farmers 220 years ago. The gold-coast chapter of the Australian American Association hosted a barbecue on Friday: The Drink nightclub in Surfers went red white and blue on Friday night.

    Reassured to know that someone’s listening, I was chastened to realise that I’d hurt someone’s feelings.

    The first caller was American. “July the 4th is our birthday,” he said. “How would you feel if someone started shouting insults at you on your birthday.”

    “Fair point,” I said, “I’ll pass your comments along to other listeners.”

    The impact of the American revolution, though, has not been all good.

    Tossing heavily taxed British tea overboard in the Boston harbour, for example, has given the septic tanks an ongoing distaste for the humble cuppa. As a result it is impossible to get a decent brew anywhere north of Atlanta and south of Ontario.

    Nevertheless, the principles of freedom and human rights enshrined by the founding fathers in the constitution of that fledgling republic still capture the imagination of freedom fighters everywhere. Ho Chi Minh, for one, used the declaration of Independence as the basis of his first speech to a newly independent Vietnam in September 1945.

    Unfortunately, those principles and the republic itself have been deliberately undermined from within. The America First movement grew from the Spanish wars with Mexico and the annexation of the Philippines in 1899 until the second world war. They largely lost the argument under Harry Truman who tested the atom bomb on innocent civilians deliberately duped into the streets to collect data on the effects of nuclear weapons. The Bretton Woods conference, The Monroe Doctrine, Kennedy’s adventurism, the shame of Chile, el Salvador and Panama naturally followed.

    Patriotic Americans, like Gore Vidal and Noam Chomsky, have written widely on the dangers of the security state that emerged to protect this imperial court. They also lament the security laws that protect the American people from the true nature of the American project.

    It has taken a cynical war in Iraq to expose once and for all that, while spouting the rhetoric of democracy and freedom, the American imperial government will blithely spent three trillion dollars, kill hundreds of thousands of people and destroy their education, health services and government, just to get their hands on the world’s last untapped oil reserves.

    As I said when I passed on my listener’s comments on Friday, “I do not want to offend those of you who celebrate the principles that founded the American republic 200 years ago, but those principles have been compromised and undermined by an empire that has thrown its shadow across the world for my entire lifetime.”

    The point of Independence From America Day is to demand that our government leads an independent, non-aligned country, not the southern-most cornerstone of someone else’s empire.

    My next caller was American, too. He moved here because his nation’s foreign policy makes him sick. Let’s hope that we become a nation that he is proud to call home.
