Increasing global water shortage emphasizes the need for demand-side water management policies, especially in the agriculture sector, being the largest consumer of freshwater. Such policies are relevant in India, where groundwater depletion may have severe implications at various socio-economic levels. In this study, using mathematical modelling, we assess the feasibility of two alternative irrigation water pricing policies – (i) uniform water pricing policy and (ii) differentiated water pricing policy, wherein farmers growing less water-requiring crops (<4488 m3/ha) get an incentive for saving water, while those growing water-intensive crops pay for it. Using a case study of Punjab, the breadbasket and one of the fastest groundwater-depleting states in India, alternative cropping patterns are also suggested. The findings reveal that the current rate of groundwater withdrawal could not sustain agricultural intensification in the state. Although optimization of resource allocation has the potential to save water by 8%, this alone is unlikely to break the rice–wheat mono-cropping pattern in Punjab. The analysis of two different volumetric irrigation water pricing policies shows that differentiated water pricing would be more effective in halting groundwater depletion in the state. However, adequate investment in irrigation water supply infrastructure, mainly for installing water meters, is required to implement the policyFull Text

Besides increasing agricultural productivity, well-developed watersheds have immense potential to minimize land degradation, mitigating the adverse impact of climate change and generating several other ecosystem services (ES). Quantifying these services is quintessential in operationalizing the concept of management and decision-making relating to watershed management. The present study estimates the value of regulating (soil conservation and carbon sequestration) and supporting ES (groundwater recharge) generated by watersheds in India, and examines the factors that influence the flow of ES from watersheds. The study followed a meta-analysis approach using information from 221 watersheds in 5 major agro-climatic zones of the country. We found that the watershed generates ES to the tune of Rs 34,113 per ha, with water recharging alone accounting for 60% of it. It shows that people’s participation in the planning, implementation and management of watersheds significantly enhances ES. Macro-watersheds (³ 1000 ha) are more effective in generating ES, underscoring the need for investment in watersheds management in the semi-arid tropical regions, where problems of degradation of natural resources are more pronounced. This study suggests policies for land restoration and payment for ES to increase their flowKeywords
