Is ‘out of sight’ truly ‘out of mind’? That’s what many water experts in India believe when it comes to our groundwater. The fact is, as a country, we are greatly dependent on groundwater, being the largest users in the world. According to reports, at just over 260 cubic km per year, India uses 25 percent of all groundwater extracted globally, ahead of the US and China.Equally significant, 70 percent of the water used in agriculture today is groundwater.In fact, according to a report by the Centre for Science and Environment (CSE) in 2012, 90 per cent of rural water and 48 per cent of urban water supply is sourced from groundwater resources. Thus, it is evident that groundwater is a lifeline for the country. That said, there is little understanding of the importance of groundwater, in both the policy and public spheres.
