Existing food security and agricultural early warning systems include FAO’s Global Information and Early Warning System (GIEWS), USAID’s Famine Early Warning Systems Network (FEWS NET), the MARS Crop Yield Forecasting System (MCYFS), the U.S. Department of Agriculture-Foreign Agricultural Service (USDA-FAS), which monitors commodity prices, food security, and trade, the World Food Programme Seasonal Monitor, and FAO’s Early Warning Early Action (EWEA) system, among others. These systems provide regular updates of food prices, food production and supply levels, harvest forecasts, weather forecasts, and food assistance needs, as well as targeted alerts regarding ongoing or anticipated food security crises at national and regional levels.
