Thriving in a Changing World Food and Water Scarcity The Impacts of Climate Change on Food Systems Climate change is profoundly altering global food systems, affecting the availability, accessibility, and quality of food. Rising temperatures, shifting precipitation patterns, and increasing frequency of extreme weather events create unprecedented challenges for agriculture, fisheries, and livestock production. These impacts threaten food security worldwide , disproportionately affecting vulnerable populations and regions already grappling with food insecurity. Rising Temperatures and Crop Yields One of the most direct impacts of climate change on food systems is the effect of rising temperatures on crop productivity. As global temperatures increase , many staple crops such as wheat, rice, and maize are experiencing reduced yields, particularly in tropical and subtropical regions. According to the Intergovernmental Panel on Climate Change (IPCC, 2021), global wheat and rice yields are ...
