This book describes the interdisciplinary work of the United States Agency for International Development (USAID)'s Famine Early Warning Systems Network (FEWS NET) and its influence on methodological and development policies in the US. FEWS NET operational needs have driven science in biophysical remote sensing applications through its collaboration with NASA, NOAA, USGS and USDA, and socio-economic methodologies through its involvement with USAID, the United Nation's World Food Program and numerous international non-governmental organizations such as Save the Children, Oxfam and others. The book describes FEWS NET's systems, methods and presents several illustrative case studies that will demonstrate the integration of physical and social science disciplines in its work.

This book describes the interdisciplinary work of USAID's Famine Early Warning System (FEWS NET) and its influence on methodological and development policies in the US. This book describes FEWS NET's systems, methods and presents several illustrative case studies that will demonstrate the integration of both physical and social science disciplines in its work. The aim of this book is to bring the work of USAID's Famine Early warning System Network into the public domain.

Famine early warning systems use remote sensing in combination with socio-economic and household food economy analysis to provide timely and rigorous information on emerging food security crises. The Famine Early Warning Systems Network (FEWS NET) is the US Agency for International Development's decision support system in 20 African countries, as well as in Guatemala, Haiti and Afghanistan. FEWS NET provides early and actionable policy guidance for the US Government and its humanitarian aid partners. As we move into an era of climate change where weather hazards will become more frequent and severe, understanding how to provide quantitative and actionable scientific information for policy makers using biophysical data is critical for an appropriate and effective response.

Global satellite data provides information on land use, rainfall, soil moisture, vegetation vigor and crop yields. Process-based products allows transformation of these data into information that can be used to assess impact of weather on commodity prices and local economic health.
