As the proverbial Indian summer sets in and taps dry up across large swathes of the country, India faces an acute shortage of safe and sustainable water, specifically groundwater, a crisis that will exacerbate with factors like indiscriminate use and climate change, warn experts.

The issue of water sustainability for the years to come centres around critical water sources such as reservoirs and groundwater.

Last week, the World Resources Institute (WRI), basing its findings on a new early warning satellite system, warned that shrinking reservoirs in India could result in water taps going completely dry in the country. Experts also point to research establishing the criticality of groundwater for India's agriculture-dependent people.
