Climate Change and Food

Progress on reducing global hunger and micronutrient deficiencies are threatened by rising temperatures, increasing extreme precipitation events (including floods and droughts), wildfires, and land degradation. Changing rainfall and temperature patterns are also spreading certain pathogens, pests, and weeds to new areas, which often negatively affect crop yields. Livestock and fisheries also are under pressure from a changing climate. In addition to affecting food quality and quantity, climate change is increasing the risks of foodborne disease and of chemical contamination entering the food chain.
