India’s Food Security Threatened by Groundwater Depletion- says expert

Dear friends, "India's Food Security Threatened by Groundwater Depletion" says Sandra Postel of National Geographic's Freshwater Initiative in Water Currents on February 3, 2015. In her article she said thatThe severe and ongoing depletion of underground water supplies in India poses a growing threat to the nation's food security. Without serious efforts to stem the mining of groundwater, food production will decline, unleashing painful social and economic consequences for this nation of 1.25 billion people. http://voices.nationalgeographic.com/2015/02/03/indias-food-security-threatened-by-groundwater-depletion/

Is there any rules across India to govern ground water harvesting? Is there any difference in policies for ground water pumping for agriculture purpose and industrial purpose?
