Crowdsourcing information can aid in early warning, says an American researcher who is working to scale up a satellite-based map of hydropower projects in the Himalayas into a mobile-phone based alert system using inputs from citizens.



Anthropologist Kelly D. Alley said people who are facing any kind of a threat related to dam infrastructure can post the information on a common platform to benefit others likely to be next in line to deal with the repercussions of the existing known danger.



Alley spearheaded the development of a satellite-based, interactive map of hydropower projects in the Himalayas called the Ganga-Brahmaputra project
