Falling underground water level may invite an acute water crisis in many states of India

Population growth, development of apartment culture in cities,and the food production mechanisms extracting more and more from the ground water reserve for irrigation have resulted into a dangerous fall of the ground water level at the rate of one foot a year in Northern-Indian states.It can lead to extensive stress on residents and economy- reports a latest research published in the current issue of Nature, the International Journal of science.

According to the latest research based on National Aeronautics and Space Administration's Satellite[NASA} Imagery about 109 cubic km of ground water has been lost within a period of last six years i.e. between 2002 and 2008.It is twice the capacity of India's largest surface water reservoir. In today's apartment culture and flood irrigation system consuming and wasting ground water by extracting the same through bore wells, the ground water is being pumped out on large scales,with a rate faster than it can be naturally replenished.This depletion of ground water is solely caused by human activities of overutilization, wastage, and misuse of ground water by through domestic use, irrigation of crop fields, construction works, supplying water to vertical dwellers, mineral water industries,factories and power plants.It is not through the natural climatic variabilities that the ground water is depleting at such a fast rate- say hydrologists.

Now, under this conditions it can be predicted that the agricultural production may be collapsed accompanied with a severe crisis of potable water in near future.Unless effective measures to recover the ground water level through effective recharge methods and mehods of judicious utilization of water are adopted on priority basis, a number of states in India including Punjab, Rajasthan, Haryana and Delhi may face acute water crisis in near future.
