This article by Lester R. Brown in the World Future Society Blog is an excellent read on the effects of wealthy sovereign and corporate interests.

Growing demand for food and fuel has put pressure on the world’s agricultural lands to produce more. Now, a trend in “land grabbing” has emerged, as wealthy countries lease or buy farms and agribusiness in poorer countries to ensure their own future supplies. The result may be further economic disparities and even “food wars.”
