Data Points: Cereal Pain

Join Our Community of Science Lovers!

After decades of stability, the global prices of such food staples as wheat, maize and rice have skyrocketed since 2004. Causes include high energy and fertilizer costs, surging demand and economic development, and a move to biofuels. Virtually all of the world’s extra corn produced from 2004 to 2007—primarily grown in the U.S.—went to make fuel. Prices may not start to decline until the middle of the next decade. In the meantime, the high costs have put tremendous stress on the world’s poor and may exacerbate regional conflicts.

Number of countries in crisis because of food prices: 36

Number in Africa: 21
