Is shrinking groundwater resources leading to socioeconomic and environmental degradation in Central Ganga Plain, India?

Abstract

In India, agriculture is a source of livelihood for over 64 % of the country's population. Indo-Gangetic Plains of North India support good cultivation and provides livelihood to several hundred million people. The climatic change studies have documented changes in precipitation pattern which can alter the flow pattern discharge to the reservoirs and availability of water for agriculture. The reduction in groundwater recharge through reduced rainfall and irregularity in surface water availability has increased dependence on groundwater resources causing its overexploitation. Consequently, pumping from deeper groundwater conditions need more energy and pump efficiency for abstraction which ultimately requires huge capital investment. Moreover, volatile fuel prices make the agricultural society vulnerable to economic losses. The repercussions of water level decline are likely to disseminate an additional economic burden to the groundwater user community. To cope with higher energy demands, increase in fuel consumption has led to environmental degradation through higher carbon emission. Thus, the groundwater depletion is likely to have far-reaching socioeconomic and environmental impacts which are not confined to the Central Gangetic Plain. In the present study, attempts have been made to analyze the effect of groundwater depletion as a commodity in the social framework of the region.
