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...

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...
