The vast “corn belt” of the Midwestern United States, the “amber waves” of wheat in India’s Punjab region, and the rice paddies of Southeast Asia – iconic landscapes that could disappear before too long.
Our three most valuable calorie sources are all in peril from the negative effects of climate change. Maize yields tend to wilt with temperatures above 30 degrees Celsius, and wheat is vulnerable to drought, a phenomenon expected to increase drastically in occurrence. Rice, the grain that feeds over half the world, is exposed to a perfect quartet of negative impacts: flooding in some areas, drought in others, heat stress, and soil salinity increases.
