" According to FAO last year (PDF), one primary reason was the cost of fuel:

Given the increased importance of biofuels and the new linkages between agricultural and energy markets, increased cereal yields, if achieved, may not necessarily continue to lead to lower cereal prices. Because the world energy market is so much larger than the world grain market, grain prices may be determined by oil prices in the energy market as opposed to being determined by grain supply.Thus, higher priced energy means more hungry people."
