Abstract:

The goal is to reconstruct past system behavior and diagnose the causes of a major water crisis.  In order to do this, we develop a hydrologic-engineering-economic model to address the complexity of urban water supply arising from consumers’ dependence on multiple interconnected sources of water. 

Groundwater conditions in the multi-aquifer system in the delta, were studied through an integrated approach using hydrochemical, hydrogeological and isotopic techniques. This study was taken up because of the reported seawater intrusion into the groundwater system of this agriculturally rich region.

NREGA is being eulogized by many in the academic, development and policy arena as a “silver bullet” for eradicating rural poverty and unemployment, by way of generating demand for productive labour force in villages and private incentives for management of common property resources.

 A large number of farmers and well operators were interviewed in the process. Data was also collected from the power utility that supplies power to this region. Along with this the climatic peculiarities of the region, farmers and well users perceptions on ground water management and use were also collected.

The historic tsunami of 2004 in the northern Indian Ocean severely affected the eastern coastal areas of peninsular India and Andaman-Nicobar Islands.

 Solar insolation changes are amongst various factors that affect sea-surface temperature, which in turn modulate global climate. Out of all the oceanic regions, equatorial region receives the maximum solar insolation and thus is the locale for the warmest waters. However, how the equatorial sea-surface temperature affects global climate, is still not clear.

 A key factor in the long-term viability of aquifer storage and recovery is the extent of mineral interaction between two dissimilar water types, their recoverable fractions and consequent impact on water quality and aquifer stability.

Indigenous knowledge is the basis for local level decision making in agriculture, healthcare, food preparation, education, natural resource management, and a host of other activities in rural communities.
