Yesterday, Members of Parliament in Lok Sabha discussed the situation of drought and drinking water crisis in many states. During the course of the discussion, some MPs also raised the issue of ground water depletion. Last month, the Bombay High Court passed an order to shift IPL matches scheduled for the month of May out of the state of Maharashtra. The court cited an acute water shortage in some parts of the state for its decision. In light of water shortages and depletion of water resources, this blog post addresses some frequently asked questions on the extraction and use of ground water in the country. Q: What is the status of ground water extraction in the country? A: The rate at which ground water is extracted has seen a gradual increase over time. In 2004, for every 100 units of ground water that was recharged and added to the water table, 58 units were extracted for consumption. This increased to 62 in 2011. Delhi, Haryana, Punjab and Rajasthan, saw the most extraction. For every 100 units of ground water recharged, 137 were extracted. In the recent past, availability of ground water per person has reduced by 15%. In India, the net annual ground water availability is 398 billion cubic metre. Due to the increasing population in the country, the national per capita annual availability of ground water has reduced from 1,816 cubic metre in 2001 to 1,544 cubic metre in 2011. Rainfall accounts for 68% recharge to ground water, and the share of other resources, such as canal seepage, return flow from irrigation, recharge from tanks, ponds and water conservation structures taken together is 32%.
