Food insecurity may arise from a number of circumstances. These may include local food availability decline (FAD), perhaps due to a below average harvest, or an entitlement decline due to a collapse in earning capacity (Chapter 9). But there are often other factors, such as distribution bottlenecks in the food system or fluctuations in world prices of grain, which may restrict commercial imports. In this chapter we discuss the types of policies that may be adopted to cope with such food insecurity, including the most obvious one, food aid.
