India’s water crisis is already here. Climate change will compound it
More than 600 million Indians face “acute water shortages,” according to a report last summer by NITI Aayog, a prominent government think tank. Seventy percent of the nation’s water supply is contaminated, causing an estimated 200,000 deaths a year. Some 21 cities could run out of groundwater as early as next year, including Bangalore and New Delhi, the report found. Forty percent of the population, or more than 500 million people, will have “no access to drinking water” by 2030. India gets more water than it needs in a given year. But the vast majority of rain falls during the summer monsoon season, generally a four-month window. The country’s other major source is melting snow and glaciers from the Himalayan plateau, which feeds rivers in the north. Capturing and delivering the water to the right places at the right times across thousands of miles, without wasting or contaminating tremendous amounts along the way, is an enormous engineering challenge. India captures and uses o
