CGIAR Climate's insight:

“Through a case study in two rice growing areas, we observed that the big climate factor limiting yields is accumulated solar energy during the grain ripening phase,” CIAT researcher and project leader Daniel Jimenez said.

The communique added that “in another case study, the analysis of historical weather data revealed that a diverse set of distinct climate patterns occurring over the years…is clearly associated with growing conditions that are favorable or not for production.”

“To ensure that crops get optimum radiation, farmers can just shift the sowing date, and to further reduce yield losses, they can adopt rice varieties that are less sensitive to the amount of radiation received,” Jimenez said.
