More than 340 delegates from 25 countries gathered at the thought-provoking sustainability summit Planet Textiles 2017 on May 24, where in the searing heat of Bangalore, the issue of water availability, use and wastewater pollution was just as topical inside the venue, as it was outside on the streets of one of India’s most rapidly expanding cities. Every year since 2012, Bangalore has been hit by drought; last year Karnataka, of which the city is the capital, has received its lowest rainfall level in four decades. Once famous as a retirement home and for its hundreds of lakes, Bangalore now has only 81 left. The rest have been filled and paved over with more than half said to be contaminated with sewage.
