Famine

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.
