By all accounts, a period we might call the Era of Cheap Food, which ran from 1980 to 2003, is over—most likely for good.
after NAFTA came into effect in 1993, subsidized U.S. corn flooded Mexican markets, slashing local corn prices by 70 percent within several years. The same dynamic has sent cheap European sugar to Africa, cheap U.S. rice to the Caribbean, and chicken from both to Ghana and Cameroon
gronomists argue that the planet is not even close to being tapped out on spare food growing capacity to nourish an expanding population. And economists say higher prices could be the wake-up call that compels politicians to create the right incentives for farmers to meet that potential.
