From 2013, the Regional Climate Systems program worked with the International Rice Research Institute (IRRI) on two projects. In one project “Determining five climate change impacts hotspots agricultural areas in Southeast Asia: Site Selection” under the Climate Change, Agriculture and Food Security (CCAFS) research program of the CGIAR, RCS determined climate change hotspots based on changes in climate extremes, rainfall decline, among others, to identify the top 10 critical areas in South East Asia. In another project, “Providing downscaled GCM (Global Climate Model) outputs for four selected rice growing regions (2x Philippines and 2x India)”, RCS provided climate change projection data to IRRI so they can check with their crop models to see how their crops will respond to a globally warm world.
