Food Security

Food security—which includes availability of food, access to food, safety of the food system, and resilience to income or food price shocks—is affected by climate change as well as a multitude of nonclimatic factors such as economic markets and agricultural policies. Because the global food system is interconnected, it is not possible to view U.S. food security in isolation. Food security in the developing world affects global political stability and, thereby, U.S. national security (see below). Studies that project the number of people at risk of hunger from climate change are highly uncertain but indicate that the outcome depends strongly on socioeconomic development, since affluence tends to reduce vulnerability.
