Última 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.

Ano: 2004 URL: http://purl.umn.edu/92832 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. Tipo: Report Palavras-chave: Irrigation management; Water management; Irrigation systems; Productivity; Rehabilitation; Models; Project evaluation; Rain; Reservoir storage; Sri Lanka; Gal Oya Project; Community/Rural/Urban Development; Crop Production/Industries; Farm Management; Productivity Analysis; Resource /Energy Economics and Policy. Ano: 1998 URL: http://purl.umn.edu/52965 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.

Ano: 2003 URL: http://purl.umn.edu/52972 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. Tipo: Report Palavras-chave: Poverty; Mapping; Food Security and Poverty. Ano: 2005 URL: http://purl.umn.edu/44546 Modernization using the structured system design of the Bhadra Reservoir Project, India: An intervention analysis AgEcon Sakthivadivel, Ramasamy; Thiruvengadachari, S.; Amarasinghe, Upali A.. 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.

Ano: 1999 URL: http://purl.umn.edu/61104 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.
