Agroclimatology

Agroclimatology

FEWS NET draws heavily on agroclimatological analysis to monitor and construct scenarios of food security in the countries it covers. Precipitation, soil moisture, and surface temperatures directly affect the ability of small- and large- scale farmers around the world to grow crops and raise livestock. Global scale patterns of atmospheric circulation and sea surface temperatures influence these variables and provide a basis for forecasting seasonal outcomes. While food security depends on a complex variety of factors, climate and weather shocks often play a significant role in episodes of acute food insecurity.

About Agroclimatology

Agroclimatology data are critical parts of FEWS NET’s knowledge base. These data include remote sensing imagery, historical rainfall totals, climate change analysis, forecasts, and an understanding of climate drivers like the El Niño-Southern Oscillation (ENSO). Analysts use this information to understand the climatology for areas of concern, to make assumptions about future conditions as part of scenario development, and to monitor and report on seasonal progress. The Ocean-Atmosphere Dynamics links below provide additional information on climate-related phenomena: El Niño, La Niña, and the Indian Ocean Dipole (IOD).

Agroclimatology information is integrated into FEWS NET’s regular Outlook and Outlook Update analysis. In addition, FEWS NET produces weekly Global Weather Hazards reports, which anticipate severe weather or climate events in Africa, Latin America and the Caribbean, and Central Asia; and Seasonal Monitor reports, which update rainfall totals, impacts on production, and short-term forecasts.

Four United States government agencies: the U.S. Geological Survey (USGS), the National Oceanic and Atmospheric Administration (NOAA), the National Aeronautics and Space Administration (NASA), and the U.S. Department of Agriculture (USDA) are indispensable partners, providing access to remote sensing imagery, data, and analysis on current conditions, historical trends, and future forecasts.
