Environmental and Geopolitical Risks of the Proposed 11,200 MW Upper Siang Multipurpose Project
GS1GS3
A recent analysis highlights the complex challenges surrounding the 11,200 MW Upper Siang dam in Arunachal Pradesh, citing severe seismic risks, ecological threats, and geopolitical sensitivities in the border region.
The proposed 11,200 MW Upper Siang Multipurpose Project in Arunachal Pradesh has emerged as a focal point of intense debate, balancing India’s developmental aspirations against significant environmental and geopolitical vulnerabilities. As one of the largest hydroelectric projects in the country, it is intended to bolster energy security and water management; however, recent analyses have raised alarms regarding its location in a highly seismic Himalayan zone.
The primary environmental concern stems from the region's susceptibility to Glacial Lake Outburst Floods (GLOFs). Given the fragile topography of the Eastern Himalayas, the construction of a massive dam could exacerbate the risk of catastrophic downstream flooding, threatening both local biodiversity and human settlements. Furthermore, the project faces significant opposition from local communities due to the potential for large-scale displacement and the loss of traditional livelihoods, raising questions about the social sustainability of such mega-infrastructure projects in ecologically sensitive areas.
