China’s recent operationalization of the Zangmu hydropower station on the Yarlung Tsangpo, the largest such station in Tibet, is an occasion to reconsider the ‘water problem’ in India-China relations. Unsurprisingly, but sadly, mainstream Indian reactions have been kneejerk and paranoid rather than based on any rational considerations.
Any dam, even run-of-the-river projects will have effects on riverine ecology. However, the impact downstream must be balanced against the fact that most of the water that contributes to the volume of the Brahmaputra beginning in Assam comes from rainfall and tributary flows on the Indian side in Arunachal Pradesh. The more important issue in India is the lack of management of river water resources; thus, a huge hydropower potential remains un- or under-exploited on the Indian side.
