If we run out of groundwater, millions of people will be left without any means to sustain themselves

The protest by farmers in Chikballapur recently, over the scarcity of drinking water, received extensive news coverage as it halted Bengaluru in its tracks after key highways were blocked. Interestingly, very little of that coverage was devoted to the groundwater crisis that underpins the problem in such regions.

Groundwater plays an important role in our lives and India’s economy, but it is disappearing fast. There is mounting evidence that we are extracting more than can be naturally replenished. In the hard-rock aquifers of peninsular India, drilling 800 ft or deeper is becoming the norm. Groundwater-dependent towns and villages spend an increasing fraction of their budgets chasing the water table. Stories abound of farmers spending their life savings or taking loans to drill a borewell, but failing to find water. If we “run out” of groundwater, millions of people will be left without any means to sustain themselves.
