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.
