Abstract

Semi-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 rain-fed 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. The remarkable developments in space technology currently offers satellites, which provide better spatial and spectral resolutions, more frequent revisits, stereo viewing and on board recording capabilities. High spatial and temporal resolution satellite data could be effectively used for watershed management and monitoring activities at land ownership level. Techniques are also successfully used for preparing detailed thematic maps, watershed development plans and continuous monitoring of the natural resources in rain-fed areas. Synergy of GIS and Web Technology allows access to dynamic geospatial watershed information without burdening the users with complicated and expensive software.

Use of smart sensor network along with GIS, RS, simulation modeling and ICT opens up new opportunities for developing intelligent watershed management information systems. These tools can help in improving the rural livelihoods and contribute substantially to meet the millennium development goals of halving the number of hungry people by 2015 and achieving food security through enhanced use
