Use of High Science Tools in Integrated Watershed Management. Proceedings of the National Symposium, 1–2 Feb 2010S PWaniauthorKRaoauthorK KGargauthorSemi-Arid Tropics (SAT) are characterized by highly variable rainfall, poor soils, low yields and poor developmental infrastructure. Watershed management is now an accepted strategy for development of rainfed agriculture in these areas. New science tools like remote sensing, geographical information systems (GIS), water balance, simulation modeling, information and communication technology (ICT) are currently being used very widely in irrigated and well-endowed areas. Importance of these tools in the SAT areas is now well understood and recognized. Application of new science tools in rain-fed agriculture opens up new vistas for development through integrated watershed management programs (IWMP). ICRISAT in partnership with national agricultural research systems and advanced research institutes in Asia has applied new science tools for enhancing the productivity of rain-fed systems in the SAT through science-led development.Watershed Management2011International Crops Research Institute for the Semi- Arid Tropics for the Semi-Arid TropicsMonograph
