Climate Change and Global Food Production

By the end of the century, the season averaged growing temperature will very likely exceed the highest temperature ever recorded throughout the tropics and subtropics. By 2050, the increase in temperature alone is projected to cause a 20% reduction in the yield of all of the major grains (maize, wheat, rice and soybeans). The breadbasket countries in the midlatitudes will experience marked increases in year-to-year volatility in crop production. Increasing stresses on the major crops due to climate change, coupled with the increasing demand for food due to increasing population and development, present significant challenges to achieving global food security. This seminar explores the likely impact of climate change and volatility on food production and availability in the foreseeable future.
