Influence of Extreme Weather Disasters on Global Cereal Production

by Coco Coyle

Increases in numbers and intensity of extreme weather disasters are linked to climate change and rising global temperatures. Agriculture is both a cause and a victim of climate change, and is susceptible to natural disasters and extreme weather disasters (EWDs). Lesk et al (2015) estimate global cereal production losses resulting from four major types of EWDs—extreme heat, droughts, extreme cold, and floods—in the period 1964–2007, analyze the underlying processes resulting in those losses, and identify several areas with potential for further study. They found that extreme heat disasters and droughts on average reduced national cereal production by 9–10%, while there was no significant drop in production from extreme cold and floods.
