Normalized Difference Vegetation Index (NDVI) images produced from Land, Atmosphere Near real-time Capability for EOS (LANCE) data are used to monitor vegetation and crop condition. U.S. Department of Agriculture (USDA) Foreign Agriculture Service (FAS) crop forecasters routinely vegetation indices produced by the Global Agricultural Monitoring project using data from LANCE to better predict crop yields. Groups such as the United Nations (UN) Food and Agriculture Organization (FAO) Desert Locust Information Service flag anomalies in vegetation.
Potentially useful data sets: Moderate Resolution Imaging Spectroradiometer (MODIS) Corrected Reflectance True Color, Land Surface Reflectance Bands 1-2-1 and 1-4-3, MODIS Snow Cover, Land Surface Temperature (day and night), MODIS Vegetation Indices - Normalized Difference Vegetation Index and Enhanced Vegetation Index.
Agro-climatic monitoring programs and global food security risks can be monitored using near real-time (NRT) MODIS data. There are several existing global/regional scale systems in place including a Famine Early Warning System (FEWS NET) which reports on drought and food shortages on a daily basis.
