The Importance of Increasing the Resilience of Food and Nutrition Security to Climate Change

While recent months have seen some easing in the pace of price increases, with the U.N. Food and Agriculture Organization Food Price Index falling from the all-time-high it reached in March 2022, higher costs for food continue to challenge low- and middle-income households worldwide. While the present crisis will end, the general trend of food price volatility and ensuing food insecurity is unfortunately likely a sign of things to come under a new climate reality.

Climate change will challenge food systems in many ways: shifting temperatures and seasons will slow growth in agricultural productivity and reduce fishery yields; the increasing frequency and severity of extreme events will raise the likelihood of crop losses; and altered precipitation and temperatures will increase water scarcity. For livestock, impacts will be felt on feed quantity and quality, water access, reproduction, productivity, and health/pathogens—likely moving nutrient-dense but already relatively expensive animal-source foods further out of the reach of low-income populations.
