The world's food situation is bleak, and shortsighted policies in the United States and other wealthy countries - which are diverting crops to environmentally dubious biofuels - bear much of the blame.
Yet the most important reason for the price shock is the rich world's subsidized appetite for biofuels. In the United States, 14 percent of the corn crop was used to produce ethanol in 2006 - a share expected to reach 30 percent by 2010. This is also cutting into production of staples like soybeans, as farmers take advantage of generous subsidies and switch crops to corn for fuel. The benefits of this strategy are dubious. A study by the Organization for Economic Cooperation and Development suggested that - absent new technologies - the United States, Canada and the European Union would require between 30 percent and 70 percent of their current crop area if they were to replace 10 percent of their transport fuel consumption with biofuels. And two recent studies suggested that a large-scale effort across the world to grow crops for biofuels would add carbon dioxide to the atmosphere rather than reduce it. The human costs of this diversion of food into energy are all too evident.
As a first step, the United States and other wealthy countries that are driving this problem must ensure that the United Nations and other relief agencies get the support they need to feed the most vulnerable people. But aid is not a solution. Congress must take a hard look at the effect of corn ethanol on food supplies in the same way the new energy bill requires it to review the environmental effects. It must move toward ending subsidies that will become even more difficult to justify as oil prices rise and the costs of producing corn ethanol decline. And it must press other wealthy countries to do the same before hunger turns to mass starvation.
