  • Widespread consensus on peak food

    By Mary Kane in the Washington Independent

    A sharp spike in prices for wheat, corn, rice and other staples has sparked riots in Mexico and Egypt, marches by hungry children in Yemen and the spectre of starving people in Haiti turning to mud pies for sustenance. This growing unrest is forcing the global community to focus on the causes of higher food costs and what can be done. But it’s also raising the troubling possibility that cheap prices for food may be gone for good, an economic relic of the the past.

    That scenario would be disastrous for the progress of fighting poverty in poor countries – and it would threaten to halt a long period of rising living standards in the United States tied directly to the inexpensive cost of food.

    “Don’t look now, but the good times may have just stopped rolling,” the economist Paul Krugman wrote in his New York Times column. The Economist was more strident: “The era of cheap food is over,” it declared. World Bank President Robert Zoellick, reaching back to policies created during the Great Depression for inspiration to address food inflation, is pushing a “New Deal” for global food policy, aimed at aiding impoverished countries with income support and help in producing crops.
    The gloom-and-doom outlooks are prompted by rising prices for commodities, which started increasing steadily in 2001 before suddenly soaring recently. Wheat prices have gone up by 181 percent over the past three years, according to the World Bank; food prices around the globe have risen by 83 percent during the same period. In March, rice prices hit a 19-year high. Corn prices recently rose from $2.50 a bushel three years ago to $6, for the first time. Zoellick has predicted a sustained period of higher food costs, saying he expects prices to remain elevated through next year and stay above 2004 levels for at least the next seven years.
    The causes are many. India and China have growing populations and are becoming more prosperous; more people can now afford to eat more meat, and the demand for animal feed has grown. In the U.S. and Europe, a boom in biofuel as alternative energy is diverting considerable amounts of corn from the market. A severe drought in Australia has contributed to a 25-year low in supplies. Some also blame speculation in the commodity markets for sharp swings in prices and availability.
    While plenty of people are worried about the end of cheap food, it’s not clear yet whether that will happen, said David Orden, senior research fellow with the International Food Policy Research Institute. Things like the weak dollar becoming stronger, crop shortfalls easing, energy prices stabilizing and strong growth in the world economy are all factors that could affect the availability of food, he said, and no one’s sure how they will play out. “We just don’t know yet,” Orden said. “Before this bump in food prices started, people were not predicting it.”
    What has become clear is that in a short time, soaring food costs have shaken some long-held assumptions about food and fuel, especially in the U.S.
    Food has been cheap in America for nearly 60 years, and Americans set aside less of their incomes for food than any other country in the world, devoting just 11 percent of disposable income to it, compared to double that percentage in Europe. Keeping food costs low has been one of the great economic achievements of the last century. The low food costs, combined with rising incomes, “have been two of the primary sources of prosperity for American consumers,” said John Urbanchuck, an agriculture industry analyst for LECG, a global consulting firm.
    Until now, Americans had the luxury of worrying about food due to its abundance. Concerns have centered on childhood obesity and an epidemic of diabetes. But new problems with food are already surfacing, as rising prices begin showing up at the grocery store. More expensive corn means people pay more for eggs and poultry, and still higher meat and milk prices are on the horizon. Record high oil prices are adding to price pressures, since transporting food costs more.
    If prices stay high for a long time, the poor will be hit the hardest, since they spend the largest percentage of their incomes on food. Efforts to reduce hunger, like food stamps and free and reduced lunch programs, will become more costly, said Otto Doering, a professor of agricultural economics at Purdue University in Indiana. Asking taxpayers to pay more for them won’t exactly be politically popular, since food prices could also take a greater bite out of middle-class budgets. And paying more for food will mean having less to spend on things like big-screen television sets and iPods, putting a dent in the kind of consumer spending that has kept the economy growing for the past two decades.
    Consumers won’t be the only ones feeling the squeeze. Hog producers in the Midwest expect to lose hundreds of millions of dollars in just the next six months due to corn price hikes, Doering said.

    It could get far worse. Another “hidden issue” is the scarcity of land still available for farming, he said. In the past, the United States had plenty of farmland to provide more crops as food demands grew. But land is finite, and after all these years, we’re beginning to run short, Doering said. “For the first time in our history, we’re pushing up against the edge in terms of quality land,” Doering said. “We’re in a somewhat fixed box.”

    Because of all this, Doering said it’s not clear whether the U.S. can keep food prices low. “It’s a whole new ballgame,” he stated.
    The United States has endured temporary price bumps before. A spike in commodities in the early 1970s was due mainly to bad weather around the world, and to huge and secretive Russian grain purchases. In 1995-96, food inflation stemmed from a Midwestern drought, global demand for U.S. feed grains and speculation. In both cases, prices settled back down again.
    This time around, the biofuel boom is also complicating the question of whether prices will revert. Some one-third of the U.S. corn crop now is devoted to ethanol production, its growth due to a combination of high oil prices and generous government subsidies. When corn prices were lower a few years ago, ethanol was seen as a popular energy alternative. Now it’s a target.
    Zoellick, the World Bank president, made headlines for blaming biofuels for recent price hikes, saying earlier this month that biofuels are a major factor in the world’s added demand for food. Biofuel mania, or speculating in commodities by hedge fund and traders betting on corn prices, was also responsible for shortages and price increases, he said.
    His remarks added to an already simmering debate. Last summer Foreign Affairs magazine published “How Biofuels Starve the Poor,” which reiterated that sentiment, noting that filling the 25-gallon tank of a sports utility vehicle with pure ethanol required 450 pounds of corn, or enough calories for one person for a year.
    At some point, American policy-makers are going to have to decide whether they want to live with an “expensive food policy” that requires continuing to produce large percentages of corn crops for biofuel and enduring higher prices for other foods, said Bruce Babcock, an Iowa State University economist.
    The food debate will eventually break down into two camps: Those who believe supply and demand are the problem, and that the world can’t produce enough to meet the needs of growing economies; and those who blame ethanol production. In the end, Babcock predicts, Washington will continue to support ethanol production in the near term, before imposing caps on its production.
    But the future for food prices will still remain uncertain, because the global market is so complex. “I don’t think we’ve ever been where we are right now,” Babcock said.
    Should prices stay high, the effect will be felt most keenly in developing countries, as the recent food riots have shown. Impoverished families now pay 50 percent to 80 percent of their incomes for food. Continuing high prices for oil and corn threaten to undo any gains in reducing poverty made over the past decade, Zoellick said.
    Josette Sheeran, head of the U.N.’s World Food Program, told The Economist that the effects of higher food prices in poor countries will be devastating:

    “For the middle classes, it means cutting out medical care. For those on $2 a day, it means cutting out meat and taking the children out of school. For those on $1 a day, it means cutting out meat and vegetables and eating only cereals. And for those on 50 cents a day, it means total disaster.”

    It wasn’t supposed to be this way. The promise of globalization was that it could lift living standards for everyone. But if the world’s hungry still can’t be fed because food is no longer cheap, it’s an empty promise

  • Angry consumers not well informed

    “The most recent example is of course the mulesing issue, with PETA and so on. I think people underestimated how they could marshal consumer outrage to create a backlash against industries,” Mr Wells said.

    “The frustration for us all in these sorts of things is when you understand the industry and the science behind these things, there’s sound reasons for doing them.

    “But there’s a disconnect, and as a scientist that’s one of the things I learnt – I used to think there was a logical process of evaluation and acquisition of data and decision making and that was the right answer. But science is only one part of the equation.”

    Mr Wells said increasingly consumers are “ruling the world”.

    “They’re increasingly expressing their wishes through big retailers who are seeking to supply them with the goods they want,” Mr Wells said.

    “So in terms of quality assurance, its gone well beyond safety and gone right back up stream to how food is produced.

    “And it includes all these soft issues which are really quite challenging for us in agriculture, but at the end of the day consumers are still not prepared to pay any more for better upstream performance and this is the frustration for industry.”

    He said if you were to poll consumers, most would say they are most concerned about issues like environment and welfare.

    “But give them an opportunity to pay more for better upstream practice and they won’t do it.

    “So the evolution has got to come with better communication and understanding to consumers about how our food is produced to reassure them that we produce food in a way that deals with a whole range of certain standards.

    “It’s a trade-off. People are worried about grocery prices but you can’t keep putting costs and expectations on upstream producers like farmers and others and then expect to absorb the cost.”

    But Mr Wells was cautious about labelling consumer expectations too high “because they rule”.

    “I think some of them are unrealistic…because they become ideological or philosophical.

    “Take for example GM canola oil – we can show that there canola oil is no different from a GM plant, and the DNA in them has identical chemicals.

    “But the ideological argument has been ‘I don’t want oil from a GM crop irrespective’.”

    Mr Wells said the farm sector had always been product-focussed rather than service-focussed, but those sorts of ideological views had nothing to do with the product.

    “It’s really about providing food service which encompasses all those other values and that’s really challenging for an industry that’s been supply-chain oriented.

    “I think the challenge for us is to actually have responsible processes to try and understand consumer trends, even if they’re irrational, and put in place processes about reassurance and quality control, even if it goes back to things that aren’t making us any more dollars.

    “It’s going to become a licence to operate rather if we do it in those ways rather than potentially an advantage in the market.”

  • Aussie drought contributes to food crisis

    An expert in science communication says the drought in Australia is one of the reasons world grain prices are increasing.

    International prices of some grains, including rice, have reached record levels.

    Professor Julian Cribb from Sydney’s University of Technology says a dramatic rise in demand for food in places like China and India is also to blame.

    “Over the last eight years the world has eaten more food every year than it has produced, that’s the bottom line, that’s why prices are going up,” he said.

    “One of the factors that has come in is that Australia, a significant grain trader, has had a drought and has not produced much grain.”

  • Extinctions related to previous warmings

    Oceans losing oxygen

    During the Jurassic, abrupt global warming of between 9 and 18 Fahrenheit (5 and 10 degrees Celsius) was associated with severe environmental change. Many organisms went extinct and the global carbon cycle was thrown off balance. One of the most intriguing effects was that the oxygen content of the oceans became drastically reduced, and this caused many marine species to die off.

    These intervals of reduced oxygen content in the oceans are now known as oceanic anoxic events, or OAEs. OAEs are associated with periods of global warming and have occurred a few times in Earth’s history. In the recent study, researchers focused specifically on the Toarcian OAE, a well-documented OAE from the early Jurassic.

    During OAEs, the remains of dead organisms and other organic matter accumulate on the ocean floor and became layers of organic-rich sediments. Today, scientists are examining the chemical and isotopic compositions of these sedimentary deposits in order to determine the actual extent to which the oceans became anoxic. By doing so, they have been able to draw connections between oxygen-depleted oceans and the disruption of Earth’s carbon cycle.

    The carbon cycle on Earth is one of the most important cycles for life as we know it. Carbon is a primary building block of life and is present in every living organism. In order for life to survive on our planet, carbon must cycle between the atmosphere, geosphere (land), hydrosphere (water) and biosphere (life). If the carbon cycle were to suddenly become disrupted, many forms of life on Earth would not survive. Even minor disruptions in the carbon cycle can have profound consequences for living organisms.

    By studying organic-rich marine deposits from the Toarcian OAE, the Open University researchers were able to compare the oxygen levels of ancient seawater to the oceans of today. The sedimentary rocks contain molybdenum, whose isotopic composition is altered depending on how oxygenated the seawater was when the sediments formed. By studying how the isotopic composition of molybdenum changed during the Toarcian OAE, scientists have developed a unique way to trace fluctuations in the oxygen content of Earth’s oceans.

    The Open University team determined that major disruptions in the global carbon cycle during the Jurassic period were intimately linked with the development of anoxic oceans and with global warming. Ultimately, this ties global warming to the demise of numerous life forms on Earth millions of years ago. Additionally, the research is providing insight into how the Earth’s oceans and atmosphere evolved over time.

    Our climate in the balance

    Modern studies of global climate change on Earth usually rely on computer modeling techniques. However, studying the history of our planet through geology can provide information on actual occurrences of climate change in the past.

    Dr. Anthony Cohen, a member of the research team, commented: “The use of current computer models to try to predict the course of climate and environmental conditions in the longer term is uncertain because of our relatively poor understanding of the great complexity of the Earth’s behaviour.  In contrast, marine sedimentary records can provide quantifiable information about precisely how the Earth has responded to severe environmental change in the past. Therefore, these records may also provide valuable constraints for testing the reliability of predictions about environmental change that will continue to occur in the future as a result of man’s activities.”

    Although the Toarcian OAE occurred roughly 183 million years ago, the findings of the recent study have important implications for our understanding of climate change today. The rates and magnitude of environmental change during ancient OAEs appear to have been similar to what we see occurring in modern times.

    By studying OAEs, scientists are able to gain important clues about how climate change might impact life on Earth in the in the coming centuries. Hopefully, their work will lead to scientific solutions that could prevent the same devastating affects on the Earth’s carbon cycle — and life itself — that were caused by global warming during the Jurassic period.

  • Timeline: The Frightening Future of Earth
  • Humans faced extinction before leaving Africa

    Wells is director of the Genographic Project, launched in 2005 to study anthropology using genetics. The report was published in the American Journal of Human Genetics.

    Previous studies using mitochondrial DNA — which is passed down through mothers — have traced modern humans to a single ”mitochondrial Eve,” who lived in Africa about 200,000 years ago.

    The migrations of humans out of Africa to populate the rest of the world appear to have begun about 60,000 years ago, but little has been known about humans between Eve and that dispersal.

    The new study looks at the mitochondrial DNA of the Khoi and San people in South Africa which appear to have diverged from other people between 90,000 and 150,000 years ago.

    The researchers led by Doron Behar of Rambam Medical Center in Haifa, Israel and Saharon Rosset of IBM T.J. Watson Research Center in Yorktown Heights, N.Y., and Tel Aviv University concluded that humans separated into small populations prior to the Stone Age, when they came back together and began to increase in numbers and spread to other areas.

    Eastern Africa experienced a series of severe droughts between 135,000 and 90,000 years ago and the researchers said this climatological shift may have contributed to the population changes, dividing into small, isolated groups which developed independently.

    Paleontologist Meave Leakey, a Genographic adviser, commented: ”Who would have thought that as recently as 70,000 years ago, extremes of climate had reduced our population to such small numbers that we were on the very edge of extinction.”

    Today more than 6.6 billion people inhabit the globe, according to the U.S. Census Bureau.

    The research was funded by the National Geographic Society, IBM, the Waitt Family Foundation, the Seaver Family Foundation, Family Tree DNA and Arizona Research Labs.

  • How the rich starved the world

     From the New Statesman

    The irony is extraordinary. At a time when world leaders are expressing grave concern about diminishing food stocks and a coming global food crisis, our government brings into force measures to increase the use of biofuels – a policy that will further increase food prices, and further worsen the plight of the world’s poor.

    What biofuels do is undeniable: they take food out of the mouths of starving people and divert them to be burned as fuel in the car engines of the world’s rich consumers. This is, in the words of the United Nations special rapporteur on the right to food, Jean Ziegler, nothing less than a “crime against humanity”. It is a crime the UK government seems determined to play its part in abetting. The Renewable Transport Fuel Obligation (RTFO), introduced on 15 April, mandates petrol retailers to mix 2.5 per cent biofuels into fuel sold to motorists. This will rise to 5.75 per cent by 2010, in line with European Union policy.

    The message could not have been clearer if the Prime Min ister, Gordon Brown, had personally put a torch to a pyre of corn and rice in Parliament Square: even as you take to the streets to protest your empty bellies and hungry children, we will burn your food in our cars. The UK is not uniquely implicated in this scandal: the EU, the United States, India, Brazil and China all have targets to increase biofuels use. But a look at the raw data confirms today’s dire situation. According to the World Bank, global maize production increased by 51 million tonnes between 2004 and 2007. During that time, biofuels use in the US alone (mostly ethanol) rose by 50 million tonnes, soaking up almost the entire global increase.

    Next year, the use of US corn for ethanol is forecast to rise to 114 million tonnes – nearly a third of the whole projected US crop. American cars now burn enough corn to cover all the import needs of the 82 nations classed by the UN’s Food and Agriculture Organisation (FAO) as “low-income food-deficit countries”. There could scarcely be a better way to starve the poor.

    The threat posed by biofuels affects all of us. Global grain stockpiles – on which all of humanity depends – are now perilously depleted. Cereal stocks are at their lowest level for 25 years, according to the FAO. The world has consumed more grain than it has produced for seven of the past eight years, and supplies, at roughly only 54 days of consumption, are the lowest on record.

    The president of the World Bank, Robert Zoellick, has already warned that 100 million people could be pushed deeper into poverty because of food price rises caused directly by this imbalance between supply and demand. Even consumers in rich countries are suffering. We now pay higher prices for our food in order to subsidise the biofuels industry, thanks to measures such as the renewable fuels directive.

    This is not just a short-term price blip, but the beginnings of a major structural change in the world food market. Population pressure – still something of a taboo subject – is also certainly playing a part. With the world population growing by 78 million a year, and expected to reach nine billion by the middle of the century, there are simply many more mouths to feed.

    In addition, rapid economic growth in India and China has created tens of millions of new middle-class consumers, all demanding western-style diets high in meat and dairy products, thereby vastly increasing the quantity of grain required for livestock production.

    Weather plays a major role, too: the FAO’s latest food situation brief reports that, in 2007, “unfavourable climatic conditions devastated crops in Australia and reduced harvests in many other countries, particularly in Europe”, while Southern Africa and the western United States have been hit hard by severe drought. Rising oil prices also increase the cost of food, as fossil fuels are important throughout the agricultural process, from tractor diesel to fertiliser production.

    Inconsistency

    The most important structural change, however, is the increasing interlinking of world energy and food markets. Once, food was just for people. Now rising demand for transport fuel – particularly in rich countries – is sucking supply away from the world food market and increasing the upward pressure on prices. In the words of Josette Sheeran, executive director of the UN World Food Programme (WFP): “We are seeing food in many places in the world priced at fuel levels,” with increasing quantities of food “being bought by energy markets” for biofuels.

    Rising oil prices feed back into the process. With food and fuel markets intertwined, increases in the price of oil are shadowed by increases in the price of grain. The real-world result from this structural shift may be that hundreds of thousands of people starve in the next few years – unless policies promoting biofuels are urgently reversed.

    This is not to suggest that government targets on biofuels are driven by some kind of malicious desire to starve the world’s poor. Indeed, both Brown and his Chancellor, Alistair Darling, have expressed concern about the food supply crisis and the role of biofuels in causing it. But for these two political leaders to voice their concerns while allowing the increased use of biofuels in the UK to be pushed forward – all in the same week – is nothing short of bizarre.

    As Oxfam’s Robert Bailey puts it: “This inconsistency at the highest levels simply beggars belief.” The aid agency calculates that the RTFO represents a £500m annual subsidy from motorists and taxpayers to the biofuels industry – more than double the amount the WFP is urgently seeking from donor countries to try to mitigate the impact of food price rises on the world’s poor.

    The EU, meanwhile, persists in the erroneous belief that biofuels can help reduce greenhouse-gas emissions. The main reason for its speedy introduction of the replacement fuel initiative was as a sop to motor manufacturers who were lobbying hard against proposed higher fuel economy standards. With biofuels, the EU hoped, it could cave in to the car industry while still getting reduction in emissions.

    Yet recent research suggests otherwise: two major studies published in Science magazine in February showed clearly that once the agricultural displacement effects of the new fuels on rainforests, peatlands and grasslands are taken into account, emissions are many times worse than from conventional mineral petrol. In other words, it would be better for the climate if we just went back to fossil fuels. Biofuels are not a “necessary but painful” way of saving the climate; they are a calamitous mistake by almost every criterion, whether social, ethical or environmental.

    Reversing the damage

    The industry claims that “second-generation” biofuels, using by-products such as corn stalks and woodchip as a feedstock, will be able to redress the balance. But if this technological advance is achieved (and that is by no means certain) it could usher in an even worse scenario: the annihilation of the world’s forests. If all plant life was seen as potentially convertible for transport fuel, there would be nothing to stop what was left of the planet’s biosphere from being strip-mined to keep rich motorists on the road. There is no simple solution. Much of the increased biofuel demand comes from the US, where Democratic and Republican politicians alike have talked themselves into a dead-end search for “energy security” – with US-grown corn top of the list.

    But the UK and the EU can reverse some of the damage by immediately ditching their own biofuels policies and providing vital aid funding, principally through the WFP, to help prevent widespread starvation in the short term. Politicians need to realise that there is no such thing as “sustainable biofuels”, either now or in the future. As for investors, they need to realise that pouring money into biofuels is a bad bet: subsidies will be quickly withdrawn when policymakers face up to the reality of their ghastly error.

    In the meantime, millions face starvation and death from increasing hunger and malnutrition. There is no time to lose.
