Staple crops suffer with extreme weather events – damages greater in developed countries – wheat, corn & Rise provide more than 50% of global calories

A new study, published Wednesday in Nature, argues that the American Midwest isn’t the only place to see staple crops like corn suffer in the face of extreme weather events. The paper, written by a team of geographers from the University of British Columbia, analyzed the effects that extreme temperatures, floods, and droughts have had on the last five decades of crop harvests. What they found was that both droughts and heat waves had a marked impact on a country’s crop production, cutting into cereal crops like wheat, rice, and maize by 10 percent and 9 percent respectively. Floods and cold spells, the study found, had no impact on crop production.
