This dataset is produced for the STRASA project in which breeders are developing varieties tolerant to salinity/sodicity. The intended use is that tolerant varieties can be sent to places with high risk of salinity/sodicity. This "salinity/sodicity" map was combined with three crop maps (GAEZv3, MIRCA2000,SPAM2005) to identify countries and hotspots, that is sites with lots of rice and lots of salinity.
