Global food commodity prices rose sharply in November to their highest level in nearly six years, the UN agency has said, due in part to adverse weather conditions. The Associated Press reports that the Food and Agriculture Organisation said prices of the most globally traded foodstuffs were up across the board, putting extra pressure in particular on 45 countries, 34 of which are in Africa. The FAO noted that the risk of above-average rainfall in Southern Africa and East Asia is a condition that may result in adverse production stocks.
