Precipitation and other climate conditions greatly impact crop production. EROS scientists monitor and forecast crop and rangeland conditions around the world through the Water Requirement Satisfaction Index (WRSI). WRSI is a tool for projecting whether there is sufficient moisture available in a given area during the growing season to result in adequate crop yields. WRSI maps are generated and distributed on a region-by-region basis at a 10-km resolution. The U.S. Geological Survey (USGS) Famine Early Warning System Network (FEWS NET) uses WRSI to assist the international community in planning for potential food shortages.
