Famine Early Warning Systems Network

The U.S. Agency for International Development (USAID) Famine Early Warning Systems Network (FEWS NET) is an information system designed to identify problems in the food supply system that potentially lead to famine or other food-insecure conditions in sub-Saharan Africa, Afghanistan, Central America, and Haiti.

The USGS FEWS NET Data Portal provides access to geo-spatial data, satellite image products, and derived data products in support of FEWS NET monitoring needs throughout the world. This portal is provided by the USGS FEWS NET Project, part of the Early Warning and Environmental Monitoring Program at the USGS Earth Resources Observation and Science (EROS) Center.

  • Interactive Map Viewer arrow Early Warning Explorer (EWX) arrow
    Interactive map viewers allow users to visualize administrative and crop zone time series of normalized difference vegetation index, dekadal (10-day) rainfall, and seasonal cumulative rainfall, including options for data download. Map Viewer EWX is an interactive web-based mapping tool that allows visualization of rainfall estimates, land surface temperature, and normalized difference vegetation index data, anomalies, z-scores and time series at varied time steps. EWX
  • Geospatial Water Requirement Satisfaction Index arrow Geospatial Stream Flow Model (GeoSFM) arrow
    The Geospatial Water Requirement Satisfaction Index (GeoWRSI) is a stand-alone implementation of the WRSI model used by USGS FEWS NET. It allows crop-specific water balance modeling of selected regions using raster data. GeoWRSI The Geospatial Stream Flow Model (GeoSFM) provides a common visual environment for monitoring wide-area hydrologic events. The model can be run operationally to identify and map the status of stream flow and soil water conditions. GeoSFM
  • Decision Support Interface (DSI) arrow
    DSI is an experimental decision support tool based on weather and crop conditions. It incorporates drought monitoring rules that distinguish severity and provide a generalized drought indicator at national and sub-national scales. DSI
