Groundwater over-exploitation and well failure are common in hard rock regions of south India. Groundwater scarcity influenced the farm input use and overall farm level technical efficiency. Data Envelopment Analysis (DEA) has been used to quantify the level of technical efficiency in different g...

Groundwater over-exploitation and efficiency in crop production: application of data envelopment analysis
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...

Total Factor Productivity (TFP) measures the growth in output which is not accounted for by inputs. Data Envelopment Analysis which forms the basis for the computation of Malmquist TFP index is used in this paper to study the performance of different river basins in Andhra Pradesh state, India. T...

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...

Purpose: Researchers and policymakers are figuring out the adaptation technologies to cope with the changing climate. Adaptation strategies for crop production followed by the farmers at selected study locations had ranged from 6-30 per cent only, and this was mainly due to lack of awareness abou...

A capacity building program on drip irrigation (TNDRIP) was undertaken in certain regions of the Indian State of Tamil Nadu during 2009-2010. An assessment of the impact of the program in terms of effective use of drip irrigation and in-creased crop yields was made in 2011 by ap-plying double dif...

Irrigation tanks in India are common property resources. Tanks provide not only for irrigation, but also forestry, fishing, domestic water supply, livestock, and other uses. Using empirical results from a study of tank performance from 80 tanks in Tamil Nadu, South India in two time period: 1996-...
