Basin-level use and productivity of water: examples from South Asia AgEcon
Molden, David J.; Sakthivadivel, Ramasamy; Habib, Zaigham.
Discusses and illustrates concepts for identifying ways of improving productivity of water within basins. The results of applying a water accounting procedure to four sub-basins in South Asia (Bhakra in India; Chishtian in Pakistan; Huruluwewa in northern Sri Lanka; and Kirindi Oya in southern Sri Lanka) are presented. The methodology used identifies the quantities and productivity of various uses of water within a basin. This information is then used to identify the water-saving potential, and the means of improving the productivity of the managed supplies.

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.

The global groundwater situation: overview of opportunities and challenges AgEcon
Shah, Tushaar; Molden, David J.; Sakthivadivel, Ramasamy; Seckler, David.
Groundwater offers us few but precious opportunities for alleviating the misery of the poor; but it poses many—and daunting—challenges of preserving the resource itself. A big part of the answer is massive initiatives to augment groundwater recharge in regions suffering depletion; but, in the ultimate analysis, these cannot work without appropriate demand-side interventions. The water vision of a world that future generations will inherit will have to be the one in which groundwater plays its full developmental, productive and environmental role but in a sustainable manner; and the framework of action to realize this vision will mean eschewing the current free-for-all in groundwater appropriation and use, and promoting a more responsible management of this...

Water scarcity and the role of storage in development AgEcon
Keller, Andrew; Sakthivadivel, Ramasamy; Seckler, David.
Of the four major ways of storing water -in the soil profile, in underground aquifers, in small reservoirs, and in large reservoirs behind dams-the first is possible only for relatively short periods of time. In this paper, the authors concentrate on the three kinds of long-term technologies, and compare the hydrological, operational, economic and environmental aspects of each.
Tipo: Report Palavras-chave: Groundwater; Water storage; Water scarcity; Reservoir storage; Costs; Aquifers; Conjunctive use; River basins; Surface water; Dams; Crop Production/Industries; Environmental Economics and Policy; Land Economics/Use; Research and Development/Tech Change/Emerging Technologies; Resource /Energy Economics and Policy.
