What effect does climate change have on our food security?

Climate change is expected to impact both rainfed and irrigated agriculture, including feed and fodder for livestock, as well as forests and aquaculture. Severe reductions in river runoff and aquifer recharge are expected in the Mediterranean Basin and in the semi-arid areas of the Americas, Australia and Southern Africa, affecting water availability and quality in already stressed regions. High latitude areas will see an increase in their potential, whereas regions near the equator will experience more frequent and severe droughts, excessive rainfall, and floods which can destroy crops and put food production at risk. Populations who live in fragile environments and depend on agriculture for their livelihoods face an immediate and increasing risk of crop failure or loss of livestock.
