The overall measure of farm-level technical efficiency is generally used to derive recommendations for the use of individual inputs. In this paper, joint estimation is made of technical and individual input-use (e.g. irrigation water productivity) efficiencies. This indicates that overall technic...

The System of Rice Intensification (SRI) - a package of practices designed to grow more rice with less water - is being widely promoted by governments and NGOs in India. In 2010-11, IWMI-Tata Program, in collaboration with local partners, undertook a study covering 2234 rice farmers in 13 major r...

Even though there has been increasing development of water management technologies over the years, the adoption rate by the farmers is comparatively small ranging from only 15-20%. Hence it is timely to look at the return to water management research investment to fine tune investment in future r...

Summary and way forward.
Groundwater is now a major source of agricultural water supply in many parts of the world. The value of groundwater as a new source of supply is well known. However, its additional buffering or stabilization value is less appreciated and even less analysed. Knowledge on groundwater?s stabilizatio...
