Electricity Prices, Groundwater and Agriculture: The Environmental and Agricultural Impacts of Electricity Subsidies in India∗

In this paper we estimate the effect of agricultural electricity subsidies in India on groundwater extraction and agricultural output. Our empirical approach exploits changes in state electricity prices over time controlling for aggregate annual shocks and fixed district unobservables. Electricity subsidies meaningfully increase groundwater extraction, where the implied extensive margin price e...

Coastal Erosion Due to Seawater Intrusion into Groundwater Aquifers

Problem Statement: In general, the drinking water systems sourced from ground water (GW) contains chemicals at double the current maximum contaminant levels (MCL) of colloids. However, due to increasing demand of water, groundwater may be subjected to over-exploitation and the natural equilibrium is thus disturbed. A steady-state condition is established between seawater and freshwater in a coa...

Environmental Isotopes in Groundwater Studies

The Property Value Impacts of Groundwater Contamination:

There are few studies examining the impacts of groundwater quality on residential property values. Using a unique dataset of groundwater well tests, we link residential transactions to home-specific contamination levels and undertake a hedonic analysis of homes in Lake County, Florida; where groundwater pollution concerns stem primarily from agricultural runoff. We find that testing and contami...

Environmental impact of seawater desalination plants.

Enormous amounts of seawater are desalted everyday worldwide. The total world production of fresh water from the sea is about 2621 mgd (9.92 million m(3) day(-1) 1985 figures). Desalting processes are normally associated with the rejection of high concentration waste brine from the plant itself or from the pretreatment units as well as during the cleaning period. In thermal processes, mainly mu...
