I removed the more clickbaity part of the headline, but this is nonetheless an excellent cautionary tale as to what the beginnings of a water shortage look like in an industrialized city.
Every year since 2012, Bangalore has been hit by drought; last year Karnataka, of which Bangalore is the capital, received its lowest rainfall level in four decades. But the changing climate is not exclusively to blame for Bangalore’s water problems. The city’s growth, hustled along by its tech sector, made it ripe for crisis. Echoing urban patterns around the world, Bangalore’s population nearly doubled from 5.7 million in 2001 to 10.5 million today. By 2020 more than 2 million IT professionals are expected to live here.
