Crop yields under climate change

16th Apr 2014

NERC scientists have contributed to a comprehensive summary of more than 1700 simulations of the impact of climate change on the yield of the major crops – rice, wheat and maize.

 

Key findings:

-without adaptation, losses in aggregate production are expected for wheat, rice and maize in both temperate and tropical regions by 2 °C of local warming,

-crop-level adaptations increase simulated yields by an average of 7–15%, with adaptations more effective for wheat and rice than maize,

-although less is known about interannual variability than mean yields, the available data indicate that increases in yield variability are likely.
