Will cleantech mobilize to prevent water shortages in India?

Two new reports this week gave urgency to efforts to reduce water use in India's agriculture sector.

That was followed by a study in the journal Nature that presented unnerving data on groundwater depletion in India, as viewed by satellites orbiting the Earth as part of NASA's Gravity Recovery And Climate Experiment. The satellites showed that the water table in India is falling 1.6 inches per year, losing 109 cubic kilometers (88.4 million acre-feet) from August 2002 to October 2008.
