Agricultural commodities prices will rise 10-30 per cent over the next 10 years compared with their average of 1997-2006, less than previously feared because of lower economic growth and oil prices, two leading organisations said on Tuesday.

“Continued weakness in the general economy will further dampen commodity prices over the next two to three years,” the United Nations’ Food and Agriculture Organisation and the Organisation for Economic Co-operation and Development said. But they added that prices “should then strengthen with economic recovery”.
