There has been a recent update from the local news agencies about China working on to build a super dam on the Brahmaputra river(highest river on Earth), which essentially will become the world's most powerful hydro power project ever executed. The dam will be built at the 'Great Bent' the most remote stretch of the Brahmaputra river. China has been planning to execute the project for the past 2 decades finally taking in shape recently. This project is projected to produce 60 GW of raw renewable energy annually. Also with China among the top CO2 emitter globally, this project will somewhat help reduce its CO2 footprint.
The concern here is the location of the project. The project is planned to be executed on the Greater Himalayan range's Great bend near Arunachal Pradesh in India (few kilometres ahead of the line of actual control) which might calls a political concern as well. Leaving the political aspects on the side, we also finds that the location is a strong earthquake prone area being the stitching point of the Indian plate with the Eurasian plate. This project thus become one of the most dangerous projects in human history. The location being on a seismologically active area, when after the project is completed and an earthquake hits the area, the effect of it will be devastating for the regions underlying the location. Also, all the hydro power projects seems environmentally sound, but the truth is they actually displace huge marine life from its creation itself, then to the flora and fauna sustaining around the region causing extinction to some species in many cases. History is evident that earthquake in the region have taken down 2 Indian dams in Uttrakhand (way below the stitching point/current super dam location) claiming many lives including the environmental devastation it wrought.
Now, coming to the political concern, India is worried about the natural flow of the river being diverted/terminated as a result of the project and the concern of flooding many parts of the country in case a major earthquake strikes. Not only that, the project is considered an act of weaponising naturally occurring water for a politically motivated target as construction will happen in the Line of Actual Control. This might even intensifies the current political tensions between the two nation. My view here is the need for intervention of International Organizations like the UN, UNSC etc as the project is putting a question mark on the natural flow of river between two countries. Not only that, the International Organizations also need to solve the political tensions which may arise out of the project apart from the environmental threat that the project brings in.
