Small farms large benefits

In the United States, farmers are experiencing the most severe drought in more than a half-century. As a result, global corn, wheat, and soybean prices rose in July and August, and remain high.

But the severe dry spell parching croplands across the US is only the latest in a global cycle of increasingly frequent and damaging droughts. In Africa's Sahel region, millions of people are facing hunger for the third time since 2005. Lack of rain in the region and volatile global food prices have made a bad situation worse.
