|Climate change is likely to diminish continued progress on global food security through production disruptions that lead to local availability limitations and price increases, interrupted transport conduits, and diminished food safety, among other causes.
Climate change can affect food availability, access, utilization, and the stability of each of these over time. Constrictions at any point can lead to food insecurity through the activities of the food system, including food production, transportation, and storage.
Climate Change, Global Food Security, and the U.S. Food System is a peer-reviewed scientific assessment that identifies climate change effects on global food security. The assessment is a contribution to the U.S. National Climate Assessment, is called for under the President’s Climate Action Plan, and was led by USDA.
