Through the long summer months in India's capital, tens of thousands of people have cut back on daily showers and laundry because of a shortage of water that has led to fighting in some areas in which three people have been killed.
Monsoon rains forecast for this week in Delhi will signal an end to the summer, but India faces the worst long-term water crisis in its history and millions of lives and livelihoods could be at risk, a think tank chaired by Prime Minister Narendra Modi has said in a report.
"We're in dire straits and we need to change our approach to tackle the crisis, otherwise the situation will become so grim that the shortages will knock down our GDP by 6 percentage points in over a decade," Avinash Mishra, a joint adviser at the Niti Aayog think tank, told Reuters.
