 Famine Early Warning Systems Network (FEWS: 2011 Report). The idea of 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. FEWS NET is a multi-disciplinary project that collects, analyzes, and distributes regional, national, and sub-national information to decision makers about potential or current famine or other climate hazards, or socioeconomic-related situations, allowing them to authorize timely measures to prevent food-insecure conditions in these nations.
