Norman Borlaug: Forgotten Benefactor of Humanity
Posted by Big Gav
While I refer fairly frequently to the "Fatal Harvest" school of thought on industrial agriculture, the original "Green revolution" is worthy of some attention - this article is about Norman Borlaug, the agronomist whose discoveries sparked the Green Revolution.
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.
