Information and data on climate, weather, and crop production used in FEWS NET analysis are provided through the collaboration of four United States government agencies: the National Aeronautics and Space Administration (NASA), National Oceanic and Atmospheric Administration (NOAA), US Department of Agriculture (USDA), and US Geological Survey (USGS).
The latest FEWS NET remote sensing products and data sets are available through portals on the USGS and NOAA websites. The products include weather forecasts and seasonal outlooks highlighting trends, hazards, and anomalies, as well as geospatial data and mapping related to vegetation, rainfall, and water use.
About Weather Hazards
The Global Weather Hazards report anticipates severe weather or climate events in Africa, Latin America and the Caribbean, and Central Asia. This product provides maps with current weather and climate information; short and medium range weather forecasts (up to one week); and the potential impact on crop and pasture conditions. It does not reflect long range forecasts or food security conditions.
About this Report
The seasonal monitor, produced by the FEWS NET USGS regional scientist and FEWS NET Regional Technical Manager, updates rainfall totals, the impact on production, and the short-term forecast. It is produced every 20 days during the production season. Find more remote sensing information here.
Periodically, FEWS NET publishes products related to the impact of the changing climate on food security. They include thematic reports, research papers, and scholarly articles ranging from such topics as rising sea surface temperatures to new rainfall patterns to water availability.

Rainfall, snowfall, sea and surface temperatures—all these directly affect the ability of small and large scale farmers around the world to grow crops, husband livestock, fish, or forage for food. While food security depends on a great complexity of factors, perhaps none is more consistently influential than the impact of weather and climate.
As the scientific community continues to study our changing climate, FEWS NET draws heavily on agroclimatology data for its food security analysis. Four United States government agencies—the National Aeronautics and Space Administration (NASA), National Oceanic and Atmospheric Administration (NOAA), US Department of Agriculture (USDA), and US Geological Survey (USGS)—are indispensable partners, providing data on current conditions, historical trends, and future forecasts.
The Partnership in Practice
NASA and NOAA collect and process satellite data, which is used by all FEWS NET partners to derive specialized products, typically represented by maps. More specifically:
- NOAA’s Climate Prediction Center provides regular weather forecasts and longerterm seasonal outlooks, highlighting trends, hazards, and anomalies.
- NASA’s Applied Sciences Program conducts interdisciplinary research and develops land surface models on vegetation and water availability.
- USGS’s Earth Resources Observation and Science Center, together with scientists and the University of California at Santa Barbara and four FEWS NET regional scientists, analyzes remote sensing and geospatial data on vegetation, rainfall, and water use to produce country and region specific depictions related to the growing season. The regional scientists are based in Botswana, Guatemala, Kenya, and Niger.
- USDA’s Foreign Agricultural Service supports in-country crop assessments.
- FEWS NET food security analysts integrate weather and climate data with information on markets and trade, nutrition, and livelihoods to evaluate current and future food security conditions for some 35 countries. FEWS NET’s worldwide field offices and Washington, DC technical office are managed by Chemonics International Inc.
FEWS NET analysts use this information to evaluate current and future conditions and make assumptions about future food security outcomes. Along with their monthly food security reports, the analysts collaborate closely with USGS regional scientists to produce seasonal monitors that track rainfall and other weather events.
