Niti Aayog's recent report on water is the latest warning about the dwindling of the supply and availability of water in the country and the scary situation it is headed for. The crisis is already here. About 60 crore people ~ nearly half of the population ~ and most cities are facing water shortage. The situation in 21 major cities will be extremely critical by 2020 and, in 10 years, the available supply may meet only half of the demand. It is not just a problem of availability.
