Remote sensing and census based assessment and scope for improvement of rice and wheat water productivity in the Indo-Gangetic basin - A working paper by Challenge Program on Water and Food
Posted on 22 Aug, 2010 04:48 PMThis paper by the Challenge Programme for Water and Food (CPWF) presents a simplified approach to combine remote sensing, census and weather data to analyze basin rice and wheat water productivity (WP) in Indo-Gangetic river basin, South Asia. It presents an innovative approach to combine meteorological data, ground survey, national census with remotely sensed imagery to assess water use, yield, and finally crop water productivity for the Indo-Gangetic rice-wheat cropping system in South Asia.
Assessing and improving water productivity in conservation agriculture systems in the Indus-Gangetic basin – A working paper by Challenge Program on Water and Food
Posted on 22 Aug, 2010 02:38 PMThe paper by Challenge Programme on Water and Food (CPWF) attempts to assess and improve water productivity in conservation agriculture systems in the Indus-Gangetic basin, in which during the past 40 years an intricate mosaic of interactions between man & nature, poverty & prosperity and problems & possibilities has emerged. Rapid expansion in agricultural water use is a common theme across these interactions and access to water is central to the livelihoods of the rural poor.
