Swiss Cook Book Aims To Give 'Frankenfood' Flavor
August 9, 2001 Reuters (Via Agnet)
ZURICH - How about a nice, steaming dish of genetically modified (GM) carrots as a way to whet skeptical consumers' appetite for scientifically engineered food? According to this story, that's one of the suggestions in what is being billed as the world's first cookbook featuring only GM ingredients, penned by an energetic champion of the controversial technology who is also a passionate cook.
Beda Stadler, a researcher at Berne's Inselspital hospital, was cited as saying he is fed up with people who brand GM products "Frankenfood" that may pose incalculable risks to the environment and human health, adding, "No other food was genetically altered as much as our daily bread," and that wheat developed from three different grasses whose genetic material managed to merge.
His book, "Genes on the Fork," is being published by InterNutrition, a group backed by a pro-GM lobbying group called the Swiss Working Group for Research and Nutrition. The group says GM foods are so thoroughly tested before they get to the dinner table that they are the safest thing to eat, while exotic plants like potatoes, maize and kiwis leapt onto menus effortlessly and without safety rules.
GM Grains Likely To Dominate
SYDNEY, Aug 9 (Reuters) - Genetically modified (GM) grains were likely to dominate world grain production because of slim price premiums for non-GM crops, an Australian government agency said in a report on Thursday.
"The world market for non-GM grain appears to be only a niche one at this stage," the federal government's commodities analyst agency, the Australian Bureau of Agricultural and Resource Economics, said in a study. Price premiums for non-GM foods, because of consumer resistance to GM products and associated market access problems, were so far limited, ABARE's executive director Brian Fisher said in a statement. "If premiums for non-GM grain do not evolve on a wide scale, it is difficult to see GM grain crops not eventually dominating world grain production systems," he said.
"Grain growers will not forgo the agronomic benefits that these crops offer if there are no penalties attached to price or market access," he said. The report showed that existing premiums for non-GM foods were thin and sketchy. It cited grain elevators in the United States paying premiums of about four to 15 percent for non-GM corn. But no consistent premium had been established on soybeans.
"If there's significant consumer resistance to GM products, then you would expect the premiums for non-GM products to be better established than they actually have been," an ABARE official quoted the report as saying.
Fisher also said that additional marketing costs associated with keeping GM grain separate in production and marketing would be an important determinant of the viability of GM grain crops. The United States faced a dilemma over the next few years on whether it would commercialise GM wheat, Fisher said. ABARE's research suggested that at present, the agronomic benefits of GM wheat crops could be largely negated by additional handling and storage costs.
"Australian growers may benefit in the short run through not having access to genetically modified crops but could face a threat to their long-run competitiveness if consumer resistance to genetically modified products dissipates," he said. But GM crops would affect the Australian grain industry irrespective of any Australian decision to adopt them or not, he said.
Adoption of GM grain crops had been rapid in north and south America and that had probably lowered prices to consumers and shifted comparative advantage in grain production in favour of the producers of these crops, he said. This was counterbalanced to some extent by consumer resistance to GM products which had led to some market access problems, he said.
Scientists Shun Talk Over GM
Waikato Times(NZ) August 4, 2001
Scientists are fearful to speak out about issues surrounding genetic modification because they are worried about their jobs and their physical safety, say people working in the field.
Hamilton scientist Doug Edmeades, a former AgResearch scientist who was the centre of a costly and bitter High Court battle over the merits of Maxi-crop, said since that government restructuring -- which saw the introduction of Crown Research Institutes (CRIs) -- scientists were less likely to speak out. "They are more cautious. They don't want to jeopardise their employment." His comments follow Green MP Sue Kedgley's claim this week that some New Zealand scientists had concerns about genetic engineering but were reluctant to speak out because they are afraid their research and their jobs would be on the line.
HortResearch group general manager Garth Smith said he could understand some scientists being reluctant to talk about genetic modification -- but for security reasons. "I can understand how they would want to keep it out of the headlines because there has been so much out there."
While no scientists at HortResearch had been the target of threats, Dr Smith said he could understand scientists working in the GM field being concerned about it. Just over two months ago former Hamilton AgResearch scientists Phil L'Hullier had his house graffitied, and anti-GM protesters are believed to be responsible for throwing a molotov cocktail over AgResearch fences.
When German scientist Goetz Laible took over from Dr L'Hullier as the lead scientist on the human genes in cows experiment, he said his own safety was something that was always in the back of his mind. "Security has always been an issue right from the beginning, especially in the genetics area."
Royal Society of New Zealand spokesman Professor George Petersen said he had no doubts scientists working on genetic modification faced security threats, which could become worse following the Royal Commission's decision to let GM field trials go ahead. "The Green Party have already said they will take action if any more field trials go ahead. I think it is really just terrorism."
Prof Petersen from Otago University said he could also understand Crown Research Institutes like AgResearch and HortResearch being reluctant to talk about GM issues. "CRIs don't want to attract problems. Look at Tony Connor, these people put in years of work and to have someone come in and just tear them out, it's a waste," said Prof Petersen. Crop and Food scientist Tony Connor had his GM potatoes destroyed by anti-GM campaigners last year.
Green Revolution, Technological Change, and Land Conversion
- Unpublished Letter to the Editor of 'Science'
Tilman et al.'s recent article (April 13, p. 281-84) errs in its oversimplification of challenges and solutions to the dilemma of meeting global food needs while conserving natural habitat and biodiversity. The authors report that despite exponential population and economic growth, temporal growth in selected environmental indicators has been linear. But for the technical innovations of the green revolution, conversion rates of natural lands to agricultural uses would indeed have been significantly higher (1-2). Yet they fail to recognize the green revolution’s contributions to natural resource conservation.
Using Tilman et al's approach, economic growth is simply a problem. In reality, economic development can pose environmental problems while simultaneously effecting solutions resulting in net environmental benefits (1). Extending their analysis from 1900, demonstrates that total cropland is apparently reaching a plateau (1, 3) and Figure 1B shows only minor increases in cropland since the late 1980s. These trends are probably better-explained using quadratic functions – which suggests that economic growth is part of the solution, not just the problem.
In contrast to the Tilman et al. scenario, flattening of the cropland curve indicates that if technological innovation continues along its present course, net land conversion should approach zero and, possibly, be reversed.
We agree with Tilman et al. that biotechnology is consistent with more environmentally benign agricultural practices. Several biotechnology-derived crop varieties -- in use since 1996 -- have begun to yield environmental benefits in terms of reduced pesticide applications, decreased energy use, and increased conservation of soil and water. New varieties in development should increase efficiencies in agricultural use of land, nitrogen, phosphorus, and water (4). The magnitude of environmental benefits from such biotechnology-derived crops would vary with crop variety, pest and abiotic pressures.
Biotechnology, like the green revolution, is part of the continuum of technological change that might eventually help farmers grow more food on less land using more environmentally benign strategies.

Subject: The 'ngin' position
I just want to be clear on the facts. The Norfolk Genetic Information Network has made it absolutely clear that their position on genetically modified Bt crops. They feel the crops are inherently dangerous and should be banned even though the use of Bt crops is resulting in millions of fewer pounds of pesticide being sprayed on fields. At the same time they state that using a toxic chemical that blocks normal chromosome separation during cell division is non-gm and therefore OK. Forcing two different species ( a grass and wheat ) to mate by poisoning normal cell division is OK. The result of the colchicines treatment is the mixing of thousands of genes from two different species.
I don't quite understand how moving a few genes between species is wrong but moving thousands of genes between species is OK and non-GM

Ecologists Agree: We're No Smarter Than Nature
- Jay Withgott, BioMedNet News 6 August 2001, http://news.bmn.com/news/story?day=010807&story=2
Corporate models of farming took it on the chin at the Ecological Society of America conference today, as participants railed at heavy pesticide use as an unsustainable practice for agriculture.
Traditionally, most ecologists have been reluctant to apply their understanding of natural systems to the much-simplified artificial ecosystems that farm fields represent. But ecologists at the symposium on ecology and agriculture felt no such hesitation. "The more effectively insects are killed, the more effectively they evolve resistance," said University of Illinois entomologist May Berenbaum.
Berenbaum honed in on the central irony of chemical usage: The strategies currently used in pesticide application - application of insecticides to large areas for prolonged periods of time every generation, with the goal of destroying every last bug - are a perfect recipe for natural selection of evolution resistance. More than 500 arthropod species are known to have evolved resistance to insecticides and more than 140 weed species to herbicides thus far. Higher doses of the chemicals are being used with less effect every year, says Matt Liebman of Iowa State University.
Some insects have shown behavioral changes along with changes in physiology. For instance, Illinois farmers held the corn rootworm at bay for 30 years by rotating crops, planting corn in a given field one year and soybeans the next. The corn-munching rootworms would lay their eggs, which would overwinter in the field. Come spring, the rootworm larvae would hatch into a sea of soybeans, and promptly starve to death.
Recently, however, the bugs have evolved two ways of dealing with their predicament, Berenbaum says. Some fly to nearby soybean fields and lay eggs there, and others stay dormant for two winters instead of one, waiting to hatch in the "correct" year.
Using chemicals to fight insects that eat plants is nothing new: Plants themselves have been at it for millions of years. But, Berenbaum says, plants conduct their chemical warfare differently, and more effectively. Rather than broadcast a chemical wantonly in every direction before an insect is even on the scene, many plants conserve their defenses until they are attacked, and limit their toxins to specific sites. They also boast a complex arsenal of many chemicals, whereas humans often rely on one at a time.
Berenbaum studies wild parsnip plants and the webworms that devour the plant's flowers and fruit. The plants defend themselves with a battery of different furanocoumarins, so webworms choose plants with lower furanocoumarin concentrations. In the co-evolutionary arms race between plant and insect, Berenbaum has found that the plants produce many fruit lacking seeds, which pack only one-third as many furanocoumarins as seeded fruits. The webworms eat the seedless fruit of no value to the plant, while the fruit with seeds survives. Seedless fruits thus serve "as decoys that divert webworms away from viable fruit," said Berenbaum.
The plant's strategy may appear to cut into its immediate yield, but "plants are less concerned with maximizing yield than they are with maximizing reproductive output" in the long term, she said. That's a lesson Berenbaum thinks humans need to take to heart: Farmers and their crops both share the same goal but "plants are in it for the long haul, and don't spend a lot of time and energy in revenge mentality."
The next frontier - crops bioengineered with genes to fight insects - may be no more immune from the forces of evolution. "We have every reason to believe that resistance will be a problem with transgenic crops," said Berenbaum. As Bt-corn and Roundup-ready soybeans occupy more fields, cases of resistance have already popped up.
What then is the solution? Berenbaum suggests using the decoy principle in a different way: Mixing in non-crop plants might lure insect pests away from crops and onto the decoy species, a strategy now practiced to lure lygus bugs off cotton and onto alfalfa. "One of the best hopes for resistance management is to diversify the landscape," Berenbaum said.
Liebman echoed many of Berenbaum's concerns and solution and says that in crop rotation, as compared to monocultures, weeds decreased in 82% of cases and increased in only 3%. Following the other presentations, Harvard University's Richard Levin suggested that pesticide practices may indeed change. "The chemical dependency we have now is a brief successional stage in the history of agriculture, and we're already passing out of it," he said.
Technological Advances Enhance Life Span, UH Economics Professor Contends
DeGregori’s New Book Explores How Misinformation Often Leaves Mistaken Impression of Food Safety
HOUSTON, July 24, 2001 – Technological advances are not killing us, they are keeping us alive, a University of Houston economics professor contends in a recently published book. For instance, the use of chemicals, – including DDT and other pesticides – ,are often maligned as damaging to the environment and the quality of life. But Thomas DeGregori , UH professor of economics, counters this argument with documentation that demonstrates how use of these chemicals has actually increased life span.
The advent of nitrogen fertilization has allowed the world to increase its population as well. "Since 1950 India’s population has tripled but its food supply has gone up four times, this is because of the Green Revolution," says DeGregori. "Our food is safer and yet we have an industry predicated on the fact that modern food is unsafe. Today’s food is more nutritious than ever before. DeGregori says a goal of the book is to debunk conventional perceptions that many technological advances in agriculture are harmful, because this is misinformation, not science. View excerpts from the DeGregori interview at:
"Science and technology have not only transformed developed countries, but they have transformed developing countries." This is an important point to focus on as the divide between rich and poor nations increases. Without technological advances in the developing world this trend would be even more striking.

Sustainable Agriculture in the Developing World: Innovative Examples
Symposium at the 2002 AAAS Annual Meeting; February 18, 2002; Boston, Massachusetts
Hunger and malnutrition are common concerns that dominate many developing countries in Asia, Latin America, and Africa. Environmental degradation associated with unsustainable agricultural practices is another great concern. Developing countries share an urgent need to battle the problems related to the health of the environment, food security, unsustainable food production, unequal distribution of food, and poverty. While some countries are more advanced in developing and implementing appropriate approaches to sustainable agriculture, others are still lagging behind. Through cooperation among these countries, expertise and know-how will be exchanged and indigenous capacity can be generated, managed, and utilized in ways that address each country's own basic needs.
The symposium will showcase successful approaches and techniques in sustainable agriculture developed and/or implemented by developing countries. Representatives from developing countries in Asia, South America, the Caribbean and Africa will share lessons learned on how to balance food security and ecological concerns and how to address hunger and unequal distribution of food. Speakers will also provide a developing country perspective on what is considered "sustainable agriculture" and how that perception may be different from that of researchers and practitioners in the U.S. and Europe. The symposium will also address:
- Challenges facing developing countries in their efforts to foster sustainable agriculture practices;
- Best practices, technologies and models of agricultural development for economic stability, food security, and environment protection in different regions of the world; and
- International cooperation in sustainable agricultural research and application
GM eggs and ham, Sam-I-am?
By Tracy Sayler
(A Gem from the Past AgBioView - May 15, 2000)
I am an ag freelancer and write often about ag policy and research matters. I also write a monthly humor column carried by several ag mags in the U.S. The following dispatch which I penned is in a significantly lighter vein than much of the topic matter disseminated through AgBioView. It relates nonetheless, and should go over well with this audience.
Perhaps you’ve heard that an alliance of biotech companies has launched a multi-million dollar ad campaign to better explain genetically-modified technology to U.S. consumers.
The Council for Biotechnology Information (CBI) includes Dupont and Monsanto among its membership. The campaign was launched in the U.S., and may be expanded to Europe, where the gene scene, as you know, has been even more controversial. The CBI’s campaign is multi-media, including TV commercials, print advertising, and a web site, www.whybiotech.com.
How should this complex issue be explained to the masses? To stand out and be understood, I think the message should be simple. Genetically engineered or genetically enhanced? How about DNA fortified? Genetically Modified Organism (GMO) or genetically modified (GM)? Heck, we don’t even know what to call the technology yet, let alone explain it.
Perhaps the educational effort should employ a bit of pop culture, such as a literary tweak to the Dr. Seuss classic, "Green Eggs and Ham."
'Do you like GM eggs and ham?'
I do not like them, Sam-I-am. I do not like GM eggs and ham.
'Would you like them here or there?'
I would not like them here or there. I would not like them anywhere. I do not like GM eggs and ham. I do not like them, Sam-I-am!
'What if the president ate them in the White House? What if they didn’t harm a lab mouse?'
I do not care if the president eats them in the White House. I do not care if they don’t harm a lab mouse. I do not like GM eggs and ham, I do not like them, Sam-I-am!
'What if they came in a microwaveable box? Or endorsed by celebrity Michael J. Fox?'
Not in a box, not with Michael J. Fox. Not in the White House, not with a lab mouse. I would not eat them here or there, I would not eat them anywhere. I would not eat GM eggs and ham, I do not like them, Sam-I-am!
'Would you? Could you? In a car? Eat them! Eat them! Here they are.'
I would not, could not, in a car. Get away from me. Go real far!
'You may like them, you will see. You may like them watching TV!'
I would not, could not with TV. And not in a car. Now let me be!
'A train! A train! Could you, would you, on a train?'
Not on a train! Not with TV! Not in a car. Sam! Let me be!
'In the dark? Here in the dark! Would you, could you, in the dark?'
I would not, could not, in the dark. I do not like GM eggs and ham. I do not like them, Sam-I-am!
'With catsup served by my pretty niece? And a bottle of beer to wash down a piece?'
Not with catsup served by your niece. Maybe the beer but no other piece. I do not like GM eggs and ham, I do not like them, Sam-I-am!
'If you were paid by Bill Gates? With money in lots of crates? Or bought them off the Internet, at tax-free discount rates?'
Not if paid by Bill Gates, with money in lots of crates. Not even off the Internet, at tax-free discount rates. I do not like GM eggs and ham, I do not like them, Sam-I-am!
'You do not like them, so you say. Try them! Try them! And you may! Try them and you may, I say!'
Sam. If you will let me be, I will try them, you will see… Say! I like GM eggs and ham! They taste no different than before, they taste so good I’ll have some more! I did not turn green by eating them here, Europe and Frito-Lay should have no fear! So they’re safe for me, the kids and wife, Greenpeace really should get a life! I will eat them here and there, I will eat them anywhere! I do so like GM eggs and ham! Thank you, thank you, Sam-I-am!

(Another blast from the past!.......CSP)
'Norman Borlaug, the agronomist whose discoveries sparked the Green Revolution, has saved literally millions of lives, yet he is hardly a household name'
AMERICA has three living winners of the Nobel Peace Prize, two universally renowned and the other so little celebrated that not one person in a hundred would be likely to pick his face out of a police lineup, or even recognize his name. The universally known recipients are Elie Wiesel, who for leading an exemplary life has been justly rewarded with honor and acclaim, and Henry Kissinger, who in the aftermath of his Nobel has realized wealth and prestige. America's third peace-prize winner, in contrast, has been the subject of little public notice, and has passed up every opportunity to parley his award into riches or personal distinction. And the third winner's accomplishments, unlike Kissinger's, are morally unambiguous. Though barely known in the country of his birth, elsewhere in the world Norman Borlaug is widely considered to be among the leading Americans of our age.
Borlaug is an eighty-two-year-old plant breeder who for most of the past five decades has lived in developing nations, teaching the techniques of high-yield agriculture. He received the Nobel in 1970, primarily for his work in reversing the food shortages that haunted India and Pakistan in the 1960s. Perhaps more than anyone else, Borlaug is responsible for the fact that throughout the postwar era, except in sub-Saharan Africa, global food production has expanded faster than the human population, averting the mass starvations that were widely predicted -- for example, in the 1967 best seller Famine -- 1975! The form of agriculture that Borlaug preaches may have prevented a billion deaths.
Yet although he has led one of the century's most accomplished lives, and done so in a meritorious cause, Borlaug has never received much public recognition in the United States, where it is often said that the young lack heroes to look up to. One reason is that Borlaug's deeds are done in nations remote from the media spotlight: the Western press covers tragedy and strife in poor countries, but has little to say about progress there. Another reason is that Borlaug's mission -- to cause the environment to produce significantly more food -- has come to be seen, at least by some securely affluent commentators, as perhaps better left undone. More food sustains human population growth, which they see as antithetical to the natural world.
The Ford and Rockefeller Foundations and the World Bank, once sponsors of his work, have recently given Borlaug the cold shoulder. Funding institutions have also cut support for the International Maize and Wheat Center -- located in Mexico and known by its Spanish acronym, CIMMYT -- where Borlaug helped to develop the high-yield, low-pesticide dwarf wheat upon which a substantial portion of the world's population now depends for sustenance. And though Borlaug's achievements are arguably the greatest that Ford or Rockefeller has ever funded, both foundations have retreated from the last effort of Borlaug's long life: the attempt to bring high-yield agriculture to Africa.
The African continent is the main place where food production has not kept pace with population growth: its potential for a Malthusian catastrophe is great. Borlaug's initial efforts in a few African nations have yielded the same rapid increases in food production as did his initial efforts on the Indian subcontinent in the 1960s. Nevertheless, Western environmental groups have campaigned against introducing high-yield farming techniques to Africa, and have persuaded image-sensitive organizations such as the Ford Foundation and the World Bank to steer clear of Borlaug. So far the only prominent support for Borlaug's Africa project has come from former President Jimmy Carter, a humanist and himself a farmer, and from the late mediagenic multimillionaire Japanese industrialist Ryoichi Sasakawa.
Reflecting Western priorities, the debate about whether high-yield agriculture would be good for Africa is currently phrased mostly in environmental terms, not in terms of saving lives. By producing more food from less land, Borlaug argues, high-yield farming will preserve Africa's wild habitats, which are now being depleted by slash-and-burn subsistence agriculture. Opponents argue that inorganic fertilizers and controlled irrigation will bring a new environmental stress to the one continent where the chemical-based approach to food production has yet to catch on. In this debate the moral imperative of food for the world's malnourished -- whether they "should" have been born or not, they must eat -- stands in danger of being forgotten.
THE LESSON OF THE DUST BOWL
NORMAN BORLAUG was born in Cresco, Iowa, in 1914. Ideas being tested in Iowa around the time of his boyhood would soon transform the American Midwest into "the world's breadbasket," not only annually increasing total production -- so methodically that the increases were soon taken for granted -- but annually improving yield, growing more bushels of grain from the same amount of land or less. From about 1950 until the 1980s midwestern farmers improved yields by around three percent a year, more than doubling the overall yield through the period. This feat of expansion was so spectacular that some pessimists declared it was a special case that could never be repeated. But it has been done again, since around 1970, in China.
Entering college as the Depression began, Borlaug worked for a time in the Northeastern Forestry Service, often with men from the Civilian Conservation Corps, occasionally dropping out of school to earn money to finish his degree in forest management. He passed the civil-service exam and was accepted into the Forest Service, but the job fell through. He then began to pursue a graduate degree in plant pathology. During his studies he did a research project on the movement of spores of rust, a class of fungus that plagues many crops. The project, undertaken when the existence of the jet stream was not yet known, established that rust-spore clouds move internationally in sync with harvest cycles -- a surprising finding at the time. The process opened Borlaug's eyes to the magnitude of the world beyond Iowa's borders.
At the same time, the Midwest was becoming the Dust Bowl. Though some mythology now attributes the Dust Bowl to a conversion to technological farming methods, in Borlaug's mind the problem was the lack of such methods. Since then American farming has become far more technological, and no Dust Bowl conditions have recurred. In the summer of 1988 the Dakotas had a drought as bad as that in the Dust Bowl, but clouds of soil were rare because few crops failed. Borlaug was horrified by the Dust Bowl and simultaneously impressed that its effects seemed least where high-yield approaches to farming were being tried. He decided that his life's work would be to spread the benefits of high-yield farming to the many nations where crop failures as awful as those in the Dust Bowl were regular facts of life.
In 1943 the Rockefeller Foundation established the precursor to CIMMYT to assist the poor farmers of Mexico, doing so at the behest of the former Secretary of Agriculture Henry Wallace, of the Pioneer Hi-Bred seed company family, who had been unable to extract any money from Congress for agricultural aid to Mexico. Soon Borlaug was in Mexico as the director of the wheat program -- a job for which there was little competition, backwater Mexico in the 1940s not being an eagerly sought-after posting. Except for brief intervals, he has lived in the developing world since.
The program's initial goal was to teach Mexican farmers new farming ideas, but Borlaug soon had the institution seeking agricultural innovations. One was "shuttle breeding," a technique for speeding up the movement of disease immunity between strains of crops. Borlaug also developed cereals that were insensitive to the number of hours of light in a day, and could therefore be grown in many climates.
Borlaug's leading research achievement was to hasten the perfection of dwarf spring wheat. Though it is conventionally assumed that farmers want a tall, impressive-looking harvest, in fact shrinking wheat and other crops has often proved beneficial. Bred for short stalks, plants expend less energy on growing inedible column sections and more on growing valuable grain. Stout, short-stalked wheat also neatly supports its kernels, whereas tall-stalked wheat may bend over at maturity, complicating reaping. Nature has favored genes for tall stalks, because in nature plants must compete for access to sunlight. In high-yield agriculture equally short-stalked plants will receive equal sunlight. As Borlaug labored to perfect his wheat, researchers were seeking dwarf strains of rice at the International Rice Research Institute, in the Philippines, another of the Ford and Rockefeller Foundations' creations, and at China's Hunan Rice Research Institute.
Once the Rockefeller's Mexican program was producing high-yield dwarf wheat for Mexico, Borlaug began to argue that India and other nations should switch to cereal crops. The proposition was controversial then and remains so today, some environmental commentators asserting that farmers in the developing world should grow indigenous crops (lentils in India, cassava in Africa) rather than the grains favored in the West. Borlaug's argument was simply that since no one had yet perfected high-yield strains of indigenous plants (high-yield cassava has only recently been available), CIMMYT wheat would produce the most food calories for the developing world. Borlaug particularly favored wheat because it grows in nearly all environments and requires relatively little pesticide, having an innate resistance to insects.
CIMMYT's selectively bred wheat, no longer a wholly natural plant, would not prosper without fertilizer and irrigation, however. High-yield crops sprout with great enthusiasm, but the better plants grow, the more moisture they demand and the faster they deplete soil nutrients. Like most agronomists, Borlaug has always advocated using organic fertilizers -- usually manure -- to restore soil nutrients. But the way to attain large quantities of manure is to have large herds of livestock, busily consuming the grain that would otherwise feed people. Inorganic fertilizers based on petroleum and other minerals can renew soil on a global scale -- at least as long as the petroleum holds out.
THE GREEN REVOLUTION
To Borlaug, the argument for high-yield cereal crops, inorganic fertilizers, and irrigation became irrefutable when the global population began to take off after the Second World War. But many governments of developing nations were suspicious, partly for reasons of tradition (wheat was then a foreign substance in India) and partly because contact between Western technical experts and peasant farmers might shake up feudal cultures to the discomfort of the elite classes. Meanwhile, some commentators were suggesting that it would be wrong to increase the food supply in the developing world: better to let nature do the dirty work of restraining the human population.
Yet statistics suggest that high-yield agriculture brakes population growth rather than accelerating it, by starting the progression from the high-birth-rate, high-death-rate societies of feudal cultures toward the low-birth-rate, low-death-rate societies of Western nations. As the former Indian diplomat Karan Singh is reported to have said, "Development is the best contraceptive." In subsistence agriculture children are viewed as manual labor, and thus large numbers are desired. In technical agriculture knowledge becomes more important, and parents thus have fewer children in order to devote resources to their education.
In 1963 the Rockefeller Foundation and the government of Mexico established CIMMYT, as an outgrowth of their original program, and sent Borlaug to Pakistan and India, which were then descending into famine. He failed in his initial efforts to persuade the parastatal seed and grain monopolies that those countries had established after independence to switch to high-yield crop strains.
Despite the institutional resistance Borlaug stayed in Pakistan and India, tirelessly repeating himself. By 1965 famine on the subcontinent was so bad that governments made a commitment to dwarf wheat. Borlaug arranged for a convoy of thirty-five trucks to carry high-yield seeds from CIMMYT to a Los Angeles dock for shipment. The convoy was held up by the Mexican police, blocked by U.S. border agents attempting to enforce a ban on seed importation, and then stopped by the National Guard when the Watts riot prevented access to the L.A. harbor. Finally the seed ship sailed. Borlaug says, "I went to bed thinking the problem was at last solved, and woke up to the news that war had broken out between India and Pakistan."
Nevertheless, Borlaug and many local scientists who were his former trainees in Mexico planted the first crop of dwarf wheat on the subcontinent, sometimes working within sight of artillery flashes. Sowed late, that crop germinated poorly, yet yields still rose 70 percent. This prevented general wartime starvation in the region, though famine did strike parts of India. There were also riots in the state of Kerala in 1966, when a population whose ancestors had for centuries eaten rice was presented with sacks of wheat flour originating in Borlaug's fields.
Owing to wartime emergency, Borlaug was given the go-ahead to circumvent the parastatals. "Within a few hours of that decision I had all the seed contracts signed and a much larger planting effort in place," he says. "If it hadn't been for the war, I might never have been given true freedom to test these ideas." The next harvest "was beautiful, a 98 percent improvement." By 1968 Pakistan was self-sufficient in wheat production. India required only a few years longer. Paul Ehrlich had written in The Population Bomb (1968) that it was "a fantasy" that India would "ever" feed itself. By 1974 India was self-sufficient in the production of all cereals. Pakistan progressed from harvesting 3.4 million tons of wheat annually when Borlaug arrived to around 18 million today, India from 11 million tons to 60 million. In both nations food production since the 1960s has increased faster than the rate of population growth. Briefly in the mid-1980s India even entered the world export market for grains.
Borlaug's majestic accomplishment came to be labeled the Green Revolution. Whether it was really a revolution is open to debate. As Robert Kates, a former director of the World Hunger Program, at Brown University, says, "If you plot growth in farm yields over the century, the 1960s period does not particularly stand out for overall global trends. What does stand out is the movement of yield increases from the West to the developing world, and Borlaug was one of the crucial innovators there." Touring the subcontinent in the late 1960s and encountering field after field of robust wheat, Forrest Frank Hill, a former vice-president of the Ford Foundation, told Borlaug, "Enjoy this now, because nothing like it will ever happen to you again. Eventually the naysayers and the bureaucrats will choke you to death, and you won't be able to get permission for more of these efforts."
THE HIGH-YIELD BOOM
For some time this augury seemed mistaken, as Borlaug's view of agriculture remained ascendant. In 1950 the world produced 692 million tons of grain for 2.2 billion people; by 1992 production was 1.9 billion tons for 5.6 billion people -- 2.8 times the grain for 2.2 times the population. Global grain yields rose from 0.45 tons per acre to 1.1 tons; yields of corn, rice, and other foodstuffs improved similarly. >From 1965 to 1990 the globe's daily per capita intake grew from 2,063 calories to 2,495, with an increased proportion as protein. Malnutrition continued as a problem of global scale but decreased in percentage terms, even as more than two billion people were added to the population.
The world's 1950 grain output of 692 million tons came from 1.7 billion acres of cropland, the 1992 output of 1.9 billion tons from 1.73 billion acres -- a 170 percent increase from one percent more land. "Without high-yield agriculture," Borlaug says, "either millions would have starved or increases in food output would have been realized through drastic expansion of acres under cultivation -- losses of pristine land a hundred times greater than all losses to urban and suburban expansion."
The trend toward harvesting more from fewer acres, often spun in the media as a shocking crisis of "vanishing farms," is perhaps the most environmentally favorable development of the modern age. Paul Waggoner, of the Connecticut Agricultural Experiment Station, says, "From long before Malthus until about forty-five years ago each person took more land from nature than his parents did. For the past forty-five years people have been taking less land from nature than their parents."
In developing nations where population growth is surging, high-yield agriculture holds back the rampant deforestation of wild areas. Waggoner calculates that India's transition to high-yield farming spared the country from having to plough an additional 100 million acres of virgin land -- an area about equivalent to California. In the past five years India has been able to slow and perhaps even halt its national deforestation, a hopeful sign. This would have been impossible were India still feeding itself with traditionally cultivated indigenous crops.
NONETHELESS, by the 1980s finding fault with high-yield agriculture had become fashionable. Environmentalists began to tell the Ford and Rockefeller Foundations and Western governments that high-yield techniques would despoil the developing world. As Borlaug turned his attention to high-yield projects for Africa, where mass starvation still seemed a plausible threat, some green organizations became determined to stop him there. "The environmental community in the 1980s went crazy pressuring the donor countries and the big foundations not to support ideas like inorganic fertilizers for Africa," says David Seckler, the director of the International Irrigation Management Institute.
Environmental lobbyists persuaded the Ford Foundation and the World Bank to back off from most African agriculture projects. The Rockefeller Foundation largely backed away too -- though it might have in any case, because it was shifting toward an emphasis on biotechnological agricultural research. "World Bank fear of green political pressure in Washington became the single biggest obstacle to feeding Africa," Borlaug says. The green parties of Western Europe persuaded most of their governments to stop supplying fertilizer to Africa; an exception was Norway, which has a large crown corporation that makes fertilizer and avidly promotes its use. Borlaug, once an honored presence at the Ford and Rockefeller Foundations, became, he says, "a tar baby to them politically, because all the ideas the greenies couldn't stand were sticking to me."
Borlaug's reaction to the campaign was anger. He says, "Some of the environmental lobbyists of the Western nations are the salt of the earth, but many of them are elitists. They've never experienced the physical sensation of hunger. They do their lobbying from comfortable office suites in Washington or Brussels. If they lived just one month amid the misery of the developing world, as I have for fifty years, they'd be crying out for tractors and fertilizer and irrigation canals and be outraged that fashionable elitists back home were trying to deny them these things."
In 1984, at the age of seventy-one, Borlaug was drawn out of retirement by Ryoichi Sasakawa, who with Jimmy Carter was working to get African agriculture moving. Carter was campaigning in favor of fertilizer aid to Africa, as he still does today. The former President had fallen in with Sasakawa, who during the Second World War had founded the National Essence Mass Party, a Japanese fascist group, but who in later life developed a conscience. Today the Sasakawa Peace Foundation is a leading supporter of disarmament initiatives; Carter and Sasakawa often made joint appearances for worthy causes.
Sasakawa called Borlaug, who related his inability to obtain World Bank or foundation help for high-yield-agriculture initiatives in Africa. Sasakawa was dumbfounded that a Nobel Peace Prize winner couldn't get backing for a philanthropic endeavor. He offered to fund Borlaug in Africa for five years. Borlaug said, "I'm seventy-one. I'm too old to start again." Sasakawa replied, "I'm fifteen years older than you, so I guess we should have started yesterday." Borlaug, Carter, and Sasakawa traveled to Africa to pick sites, and the foundation Sasakawa-Global 2000 was born. "I assumed we'd do a few years of research first," Borlaug says, "but after I saw the terrible circumstances there, I said, 'Let's just start growing.'" Soon Borlaug was running projects in Benin, Ethiopia, Ghana, Nigeria, Sudan, Tanzania, and Togo. Yields of corn quickly tripled; yields of wheat, cassava, sorghum, and cow peas also grew.
Borlaug made progress even in Sudan, near the dry Sahel, though that project ended with the onset of Sudan's civil war, in 1992. Only Sasakawa's foundation came forward with more funds, but although well endowed, it is no World Bank. Environmentalists continued to say that chemical fertilizers would cause an ecological calamity in Africa.
Opponents of high-yield agriculture "took the numbers for water pollution caused by fertilizer runoff in the United States and applied them to Africa, which is totally fallacious," David Seckler says. "Chemical-fertilizer use in Africa is so tiny you could increase application for decades before causing the environmental side effects we see here. Meanwhile, Africa is ruining its wildlife habitat with slash-and-burn farming, which many commentators romanticize because it is indigenous." Borlaug found that some foundation managers and World Bank officials had become hopelessly confused regarding the distinction between pesticides and fertilizer. He says, "The opponents of high-yield for Africa were speaking of the two as if they were the same because they're both made from chemicals, when the scales of toxicity are vastly different. Fertilizer only replaces substances naturally present in the soils anyway."
In Africa and throughout the developing world Borlaug and most other agronomists now teach forms of "integrated pest management," which reduces pesticide use because chemicals are sprayed at the most vulnerable point in an insect's life cycle. Borlaug says, "All serious agronomists know that pesticides must be kept to a minimum, and besides, pesticides are expensive. But somehow the media believe the overspraying is still going on, and this creates a bias against high-yield agriculture." Indonesia has for nearly a decade improved rice yields while reducing pesticide use by employing integrated pest management. The use of pesticides has been in decline relative to farm production for more than a decade in the United States, where the use of fertilizer, too, has started declining relative to production.
Such developments have begun to sway some of Borlaug's opposition. The Committee on Sustainable Agriculture, a coalition of environmental and development-oriented groups, has become somewhat open to fertilizer use in Africa. "The environmental movement went through a phase of revulsion against any chemical use in agriculture," says Robert Blake, the committee's chairman. "People are coming to realize that is just not realistic. Norman has been right about this all along." One reason the ground is shifting back in his direction, Borlaug believes, is that the green parties of Europe have been frightened by the sudden wave of migrants entering their traditionally low-immigration nations, and now think that improving conditions in Africa isn't such a bad idea after all.
Supposing that opposition to high-yield agriculture for Africa declines, the question becomes What can be accomplished there? Pierre Crosson, an agricultural analyst for the nonpartisan think tank Resources for the Future, calculates that sub-Saharan Africa needs to increase farm yields by 3.3 percent annually for the next thirty years merely to keep pace with the population growth that is projected. This means that Africa must do what the American Midwest did.
"Africa has the lowest farm yields in the world and also a large amount of undeveloped land, so in theory a huge increase in food production could happen," says John Bongaarts, the research director of the Population Council, a nonprofit international research organization. "If southern Sudan was parked in the Midwest, they'd be growing stuff like crazy there now." Practical problems, however, make Bongaarts think that rapid African yield increases are "extremely unlikely in the near future." The obvious obstacles are desperate poverty and lack of social cohesion. When Borlaug transformed the agriculture of Pakistan and India, those nations had many problems but also reasonably well organized economies, good road and rail systems, irrigation projects under way, and an established entrepreneurial ethos. Much of Africa lacks these.
Additionally, African countries often lack a social focus on increasing agricultural output. Young men, especially, consider the farm a backwater from which they long to escape to the city. African governments and technical ministries tend to look down on food production as an old-fashioned economic sector, longing instead for high-tech facilities that suggest Western prestige and power. Yet a basic reason that the United States and the European Union nations are so strong is that they have achieved almost total mastery over agriculture, producing ample food at ever-lower prices.
An encouraging example of an African government taking a progressive view of agriculture comes from Ethiopia, where, since the end of its civil war, Borlaug has run his most successful African project. Visiting Ethiopia in 1994, Jimmy Carter took Prime Minister Meles Zenawi on a tour of places where Borlaug's ideas could be tested, and won Zenawi's support for an extension-service campaign to aid farmers. During the 1995-1996 season Ethiopia recorded the greatest harvests of major crops in its history, with a 32 percent increase in production and a 15 percent increase in average yield over the previous season. Use of the fertilizer diammonium phosphate was the key reform. The rapid yield growth suggests that other sub-Saharan countries may also have hope for increased food production.
Whether Africa can increase its food production may soon become one of the questions of international affairs. It may be one at which, in a decade or two, Western governments will frantically throw money after a crisis hits, whereas more-moderate investments begun now might avert the day of reckoning. And one of the questions of the next century may be whether the world can feed itself at all.
10 BILLION MOUTHS
His opponents may not know it, but Borlaug has long warned of the dangers of population growth. "In my Nobel lecture," Borlaug says, "I suggested we had until the year 2000 to tame the population monster, and then food shortages would take us under. Now I believe we have a little longer. The Green Revolution can make Africa productive. The breakup of the former Soviet Union has caused its grain output to plummet, but if the new republics recover economically, they could produce vast amounts of food. More fertilizer can make the favored lands of Latin America -- especially Argentina and Brazil -- more productive. The cerrado region of Brazil, a very large area long assumed to be infertile because of toxic soluble aluminum in the soil, may become a breadbasket, because aluminum-resistant crop strains are being developed." This last is an example of agricultural advances and environmental protection going hand in hand: in the past decade the deforestation rate in the Amazon rain forest has declined somewhat, p
Borlaug continues, "But Africa, the former Soviet republics, and the cerrado are the last frontiers. After they are in use, the world will have no additional sizable blocks of arable land left to put into production, unless you are willing to level whole forests, which you should not do. So future food-production increases will have to come from higher yields. And though I have no doubt yields will keep going up, whether they can go up enough to feed the population monster is another matter. Unless progress with agricultural yields remains very strong, the next century will experience sheer human misery that, on a numerical scale, will exceed the worst of everything that has come before."
But "very strong" progress on yields seems problematic. John Bongaarts calculates that agricultural yields outside Western countries must double in the coming century merely to maintain current -- and inadequate -- nutrition levels. The United Nations projects that human numbers will reach about 9.8 billion, from about 5.8 billion today, around the year 2050. To bring the entire world's diet in that year to a level comparable to that of the West, Bongaarts calculates, would require a 430 percent increase in food production.
Lester Brown, the head of the Worldwatch Institute, an environmental organization, fears that China may soon turn from an agricultural success story into a nation of shortages. Because much of it is mountainous, China already uses most of its attractive tillage area, leaving scant room for expansion. Its remarkable improvements in wheat and rice yields have come in part, Brown thinks, at the expense of depleting the national water table: irrigation water may soon become scarce. As newly affluent Chinese consumers demand more chicken and beef, feeding increased amounts of grain to animals may cause grain scarcity. If, as some experts project, the Chinese population rises from 1.2 billion to 1.6 billion, yield increases will not bridge the difference, Brown fears.
Privatization and dwarf rice have enabled China to raise rice yields rapidly to about 1.6 tons per acre -- close to the world's best figure of two tons. But recently rice-yield increases have flattened. The International Rice Research Institute is working on a new strain that may boost yields dramatically, but whether it will prosper in the field is unknown. Ismail Serageldin, the chairman of the Consultative Group on International Agricultural Research, in Washington, D.C., believes that the "biological maximum" for rice yield is about seven tons per acre -- four times today's average in developing countries, but perhaps a line that cannot be crossed.
An important unknown is whether genetic engineering will improve agricultural yields. Corn is among the highest-yielding plants. "If the high natural multiples of maize could be transferred by gene engineering to wheat or rice, there could be a tremendous world yield improvement," Paul Waggoner, of the Connecticut Agricultural Experiment Station, says. So far genetic engineering has not produced any higher-yielding strains, though it does show promise for reducing pesticide application. Some researchers also think that biotechnology will be able to pack more protein and minerals into cereal grains. Others, Borlaug among them, are skeptical about whether yield itself can be engineered. So far gene recombination can move only single genes or small contiguous gene units. Borlaug says, "Unless there is one master gene for yield, which I'm guessing there is not, engineering for yield will be very complex. It may happen eventually, but through the coming decades we must assume that gene engineering will not be th
Today Borlaug divides his time among CIMMYT, where he teaches young scientists seeking still-more-productive crop strains for the developing world; Texas A&M, where he teaches international agriculture every fall semester; and the Sasakawa-Global 2000 projects that continue to operate in twelve African nations.
Borlaug's Africa project is a private-sector effort run by an obscure Nobel Peace Prize winner and a former American President whose altruistic impulses are made sport of in the American press. Its goal is something the West seems almost to have given up on -- the rescue of Africa from human suffering. Recently Western governments have been easing out of African aid, pleading "donor fatigue," the difficulty of overcoming corruption, and fear of criticism from the environmental lobby. Private organizations, including Borlaug's, Catholic Relief Services, and Oxfam, carry on what's left of the fight.
If overpopulation anarchy comes, it is likely to arrive first in Africa. Borlaug understands this, and is using his remaining years to work against that cataclysm. The odds against him seem long. But then, Norman Borlaug has already saved more lives than any other person who ever lived.
