Bengaluru residents fight water shortages in their own backyards

Bengaluru has empowered residents to record groundwater usage and water waste through a Participatory Aquifer Mapping Project. Community groups use crowdsourcing platforms to share information with experts, and work together to create and develop solutions to reduce their water use and identify new water sources. In a pilot project, the approach helped one community transition from a near-drought scenario to selling 25,000 litres of water per day.
