I introduced my friend, Dr Mark Everard, to India a few years ago. He is a World leading wetland environment scientist and has helped several people now with issues concerning their local rivers etc.
During a trip to Uttaranchal this year, he continued his work in opposition to the proposed Pancheshwar Dam. A case study is now available for those who would wish to oppose this project, or for anyone who would like more information about issues concerning large dam projects.
