Water Energy Nexus Activity (WENEXA) Project –The Governance Angle
This presentation highlights the importance to government of power and water sector reforms. It draws upon the experience of Maheshwaram pilot project to show the way ahead.
The Water-Energy Nexus in India: Approaches to Agrarian Prosperity with a Viable Power Industry
This paper suggests that the simultaneous management of the groundwater and energy economies, as a nexus, is a great opportunity and can be achieved. Since, in the Indian context, there seems to be no practical way to directly manage groundwater, laws are unlikely to check the chaotic race to extract it, water pricing and/or property rights reforms, too, do not promise much hope in bringing about the desired change. Power supply and pricing policy offer a useful means to initiate indirect management of both groundwater and energy use. But perfecting and using this policy effectively requires a fusion of energy and water perspectives, which fortunately is emerging as the new paradigm in power supply to agriculture in India.
Water Balance Tools to Support Water and Energy Decision-Making:
Overview and Application in Maheshwaram Watershed,
Ranga Reddy District: Andhra Pradesh
This paper presents and applies a simple yet robust water balance that is intended to serve as the basis for decision-making related to water and energy co-management. We consider the watershed to be the appropriate physical unit for water balance assessments, in principle because aquifer delineation in heterogeneous hardrock conditions is itself time- and data-intensive and fraught with inaccuracies.
Further, throughout most of India, watersheds have been delineated and in fact are already taken as the unit of management and investment for several government and non-government programs related to natural resources. Finally, based on the recognition that accurate historical data on groundwater levels may either be non-existent or prohibitively difficult to access for a number of institutional and political reasons, the water balance approach presented here derives monthly changes in the reference static groundwater level, i.e., the water level in a representative well not currently being pumped. It is not intended to be a spatially explicit model, for instance, that would provide information on where to site new wells. Instead, it should serve as a first-cut method with acceptable accuracy to support decision-making on agricultural water demand, aggregate pumping volumes, and the influence power supply and management may have on groundwater.
