Futuristic Policies Reviewing Groundwater Depletion at North- East India: A Conceptual Study

Abstract

Groundwater a very vital natural resource for human use and for irrigating crops. India is world's largest user of groundwater, but because of diversities in geomorphological and meteorological aspects, both abstraction and depletion of ground water varies state wise. The food habit and crop yield varies in terrains and valleys with strength of population and no uniform formula can exist throughout the country for assessing the depletion. Depletion however is a continuous process as groundwater recharge is also not uniform. Scenario decrees that within few decades we will land up in a crisis if we fail to create and develop a sustainable policy to reduce depletion or rather fail to recharge our aquifers. In this paper the authors intend to impress more use of satellite-based data and remote sensing technologies to near- accurate assessment of the gap between depletion and recharge of groundwater and reduce the non- renewable groundwater. Referring to various random literature and recent UN data base the authors attempt to impress about the necessary relation between the interface of science and that of policies which can control misuse for a sustainable future.
