FEWS NET, the Famine Early Warning Systems Network, is a website of information and analysis on food insecurity created in 1985 by the United States Agency for International Development (USAID), and the US Department of State, after famines in East and West Africa. In 2008, Molly E. Brown argued that during its twenty years of activity, FEWS NET had been extremely successful. She said that it was widely viewed as "the most effective program in existence for providing information to governments about impending food crises". Aims FEWS NET aims at providing information to governments, international relief agencies, NGOs, journalists, and researchers planning for, responding to, and reporting on humanitarian crises. With support from a technical team in Washington, D.C., FEWS NET staff based in more than 20 country offices collaborate with US government agencies, national government ministries and international partners to collect data and produce objective, forward-looking analysis on the world's most food-insecure countries. Using an integrated approach that considers climate, agriculture production, prices, trade, nutrition, and other factors, together with an understanding of local livelihoods, FEWS NET forecasts most likely outcomes and anticipates change six to twelve months in advance. To help decision-makers and relief agencies plan for food emergencies, FEWS NET publishes monthly reports (available on its web site) on current and projected food insecurity, up-to-the-minute alerts on emerging or likely crises, and specialized reports on weather hazards, crops, market prices, and food assistance. In 2010, to mark its 25th anniversary, FEWS NET produced a video to document its work. Methodology FEWS NET reporting focuses on acute food insecurity—sudden and/or short-term household food deficits caused by shocks—rather than chronic food insecurity, ongoing or cyclical food deficits related to persistent poverty and a lack of assets. In general, food insecurity is rarely the result of one causal factor. The strength and reliability of FEWS NET forecasting lies in its integrated consideration of the diversity of factors that lead to risk. Along with agricultural production, climate and weather, FEWS NET places analytical importance on markets and trade, livelihoods and sociopolitical issues such as conflict and humanitarian response. Key elements of FEWS NET's methodology include: Classifying food insecurity: FEWS NET describes the severity of food insecurity using the Integrated Food Security Phase Classification version 2.0 (IPC 2.0), an international five-level scale. FEWS NET representatives were among the international food security leaders who designed the scale. Scenario development is at the heart
