India facing the 'worst water crisis in its history'
India is facing its worst-ever water crisis, with some 600 million people facing acute water shortage, a government think-tank says.
The Niti Aayog report, which draws on data from 24 of India's 29 states, says the crisis is "only going to get worse" in the years ahead.
It also warns that 21 cities are likely to run out of groundwater by 2020 despite increasing demand.
This would also threaten food security as 80% of water is used in agriculture.
