ABSTRACT
Climate change is a significant threat to global food security. This chapter describes how increases in the earth’s air, surface, and ocean temperatures are undermining the production, distribution, and consumption of food worldwide, especially in the Global South. Climate change is causing land degradation, water scarcity, extreme weather events, insect infestations, the spread of crop diseases, and the decline of fish populations. Reduced food availability and higher food prices have disproportionately adverse impacts on those communities that are already the most food insecure. The chapter then advances a series of measures to reduce the causes of climate change (mitigation) and manage its adverse impacts (adaptation). Emphasis is placed on the adoption of agroecology and promotion of food sovereignty.
