Feeding the World

"Thomas Robert Malthus, the namesake of such terms as "Malthusian collapse" and "Malthusian curse," was a mild-mannered mathematician, a clergyman—and, his critics would say, the ultimate glass-half-empty kind of guy. When a few Enlightenment philosophers, giddy from the success of the French Revolution, began predicting the continued unfettered improvement of the human condition, Malthus cut them off at the knees. Human population, he observed, increases at a geometric rate, doubling about every 25 years if unchecked, while agricultural production increases arithmetically—much more slowly. Therein lay a biological trap that humanity could never escape."

"So what is a hot, crowded, and hungry world to do?"

"That's the question von Braun and his colleagues at the Consultative Group on International Agricultural Research are wrestling with right now. This is the group of world-renowned agricultural research centers that helped more than double the world's average yields of corn, rice, and wheat between the mid-1950s and the mid-1990s, an achievement so staggering it was dubbed the green revolution. Yet with world population spiraling toward nine billion by mid-century, these experts now say we need a repeat performance, doubling current food production by 2030."

"In other words, we need another green revolution. And we need it in half the time."
