Bailout with white revolution or sink deeper?: groundwater depletion and impacts in the Moga District of Punjab, India. AgEcon
Amarasinghe, Upali A.; Smakhtin, Vladimir U.; Sharma, Bharat R.; Eriyagama, Nishadi.
Moga District in Punjab, India, is a microcosm of the twin story of irrigation-induced growth and stress. The groundwater consumptive water use in agriculture exceeds the recharge by a substantial margin. Rice production contributes to a major part of this difference. The groundwater depletion is so critical that diversifying agriculture is the only way forward for sustainable agricultural growth. Reducing the rice area and intensifying milk production will be a win-win situation for both the farmers and the area reeling with a groundwater crisis.
Tipo: Report Palavras-chave: Groundwater depletion; Groundwater irrigation; Water use; Rice; Wheat; Milk production; Agricultural and Food Policy; Food Consumption/Nutrition/Food Safety; Food Security and Poverty; Production Economics; Resource /Energy Economics and Policy.

Impact assessment of rehabilitation intervention in the Gal Oya Left Bank AgEcon
Amarasinghe, Upali A.; Sakthivadivel, Ramasamy; Murray-Rust, Hammond.
Assesses the impact of rehabilitation interventions on irrigation system performance using time series analysis. The study demonstrates that with proper impact specification and model identification, the nature and magnitude of the impacts of different interventions can be separated from the effects of simultaneous changes in dominant exogenous factors.

India’s water future to 2025-2050: business-as-usual scenario and deviations AgEcon
Amarasinghe, Upali A.; Shah, Tushaar; Turral, Hugh; Anand, B.K..
With a rapidly expanding economy many changes are taking place in India today. The business-as-usual (BAU) scenario, which assumes the continuation of current trends of key water demand drivers, will meet the future food demand. However, it leads to a severe regional water crisis by 2050, where many river basins will reach closure, will be physically water-scarce and will have regions with severely overexploited groundwater resources. While the alternative scenarios of water demand show both optimistic and pessimistic water futures, the scenario with additional productivity growth is the most optimistic, with significant scope for reducing future water demand.
Tipo: Report Palavras-chave: Water demand; Water supply; Population growth; Crop production; Crop yield; Groundwater; Irrigation; Food security; Crop Production/Industries; Food Security and Poverty; Resource /Energy Economics and Policy.

Locating the poor: Spatially disaggregated poverty maps for Sri Lanka AgEcon
Amarasinghe, Upali A.; Samad, Madar; Anputhas, Markandu.
This report presents the results of subnational poverty estimation using aggregate poverty statistics and how they can help policy interventions. In particular, they estimate the poverty map across the DS division level in Sri Lanka. The poverty map depicts the proportion of households below the poverty line, which is based on household expenditure for food for obtaining the minimum calorie requirement.

Evaluates the performance of the Bhadra Reservoir Project-before, during, and after the introduction of modernization with structured system design. Analysis focuses on water management, agricultural productivity, and farmer participation and perception. Identifies the absence of a continuing support mechanism and lack of farmer participation as the major causes for the project's decline.

Spatial variation in water supply and demand across river basins of India AgEcon
Amarasinghe, Upali A.; Sharma, Bharat R.; Aloysius, Noel; Scott, Christopher A.; Smakhtin, Vladimir U.; de Fraiture, Charlotte.
India is a large country with regional differences in per-capita water supply and demand. Attempts to describe the water situation in India at a national level are often misleading due to the tremendous diversity in the water situation across the country. This Report analyzes the spatial variation of water supply and demand across river basins in India. The study identifies basins that are water-scarce because of inadequate water availability to meet the effective demand. It also identifies issues that are important for estimating the future water demand and for the formation of policy for future water-resources development and management.
Tipo: Report Palavras-chave: Water supply; Water demand; River basins; Catchment areas; Water availability; Water scarcity; Estimation; Irrigation water; Domestic water; Population growth; Urbanization; Groundwater extraction; Crop production; Policy; Water transfer; India; Agricultural and Food Policy; Community/Rural/Urban Development; Consumer/Household Economics; Crop Production/Industries; Environmental Economics and Policy; Farm Management; Food Consumption/Nutrition/Food Safety; Production Economics.
