Global food security could be notably impacted by a marked decline in crop diversity if temperatures rise by more than 1.5°C. As temperatures rise, a third of global food production could be at risk. Low-latitude regions face significantly worse consequences than mid- or high-latitudes, with up to half of the crops at risk and those regions would also see a large drop in crop diversity, reducing food security and making it more difficult to get adequate calories and protein. Warming will severely decrease global cropland available for staple crops–rice, maize, wheat, potato and soybean–which account for over two-thirds of the world’s food.
