The government on Tuesday launched Jal Shakti Abhiyan, a water conversation campaign to tackle India's acute crisis.

The campaign will focus on five aspects — water conservation and rainwater harvesting, renovation of traditional and other water bodies/tanks, reuse of water and recharging of structures, watershed development and intensive afforestation.

A total of 1,592 water-stressed blocks in 256 districts will be taken care of as a combined effort of state and central government ministries.

According to a Niti Aayog report, 21 major cities will run out of groundwater by 2020. The think tank's report added that 2 lakh people die every year due to inadequate or unsafe water.
