JRC scientists have proposed a new approach for identifying the impacts of climate change and extreme weather on the variability of global and regional wheat production. The study analysed the effect of heat and water anomalies on crop losses over a 30-year period.
JRC scientists studied the relative importance of heat stress and drought on wheat yields between 1980 and 2010. They developed a new Combined Stress Index in order to better understand the effects of concurrent heat and water stress events.
