Global biomass demand is expected to roughly double between 2005 and 2050. Current studies suggest that agricultural intensification through optimally managed crops on today's cropland alone is insufficient to satisfy future demand. In practice though, improving crop growth management through better technology and knowledge almost inevitably goes along with (1) improving farm management with increased cropping intensity and more annual harvests where feasible and (2) an economically more efficient spatial allocation of crops which maximizes farmers' profit.

During the 20th century hunger has become a problem of poverty amidst plenty rather than absolute food scarcity. The question is whether this will remain so or whether the hunger of the poor will once more be exacerbated by rising food prices. In this paper we discuss biophysical conditions, social forces and non-linear interactions that may critically influence the global availability of food in the long term.

The 2011 Global Food Policy Report is a new annual IFPRI publication that provides a comprehensive, research-based analysis of major food policy challenges at the global, regional, national, and local levels. It highlights important developments and events in food policy that occurred in 2011, discusses lessons learned, offers policy recommendations, presents IFPRI’s food policy tools and indicators, and takes a look forward into 2012. The Report reflects perspectives from across the globe.

In a world of food abundance, millions of people suffer from poor nutrition. In some parts of the world, the poor have inadequate access to energy from food to meet their energy requirements. In these locations, food shortage is often a seasonal phenomenon and micronutrients are also generally lacking in the diet. Elsewhere, there is a stable supply of energy but the poor have monotonous diets lacking in essential micronutrients.
