The State of Food Insecurity In The World 2011 highlights the differential impacts that the world food crisis of 2006-08 had on different countries, with the poorest being most affected. This year's report focuses on the costs of food price volatility, as well as the dangers and opportunities presented by high food prices. Climate change and an increased frequency of weather shocks, increased linkages between energy and agricultural markets due to growing demand for biofuels, and increased financialisation of food and agricultural commodities all suggest that price volatility is here to stay. The report describes the effects of price volatility on food security and presents policy options to reduce volatility in a cost-effective manner and to manage it when it cannot be avoided.
