Beijing: Much water has flowed since China announced in December 2024 its plan to build the world’s largest dam on the Brahmaputra River, known as Yarlung Tsangpo in Tibet, with the ambitious goal of generating 60,000 megawatts of energy annually. The USD 137 billion Medog Hydropower Station is set to commence commercial operations by 2033, capturing global attention not only for its energy potential but also for its ecological implications.
According to Global Voices, Bangladeshi officials have expressed concerns that the dam could reduce the dry season flow, prompting requests for a comprehensive environmental impact assessment, feasibility study, climate impact evaluation, and disaster impact assessment from China. This development comes amid a growing global anti-dam movement due to the social and environmental costs associated with such projects. The Himalayan region, already prone to natural disasters, faces heightened risks from the climate crisis, with the Medog Hydropower Station standing as a prominent case.
Chinese state media, however, maintains that the Medog project is both safe and ecologically considerate, positioned to aid China in achieving its carbon neutrality targets. They claim that the project will not adversely impact the lower reaches of the river and promise continued communication and cooperation with downstream countries on disaster prevention and rescue efforts.
The Brahmaputra River, a transboundary watercourse, originates in Tibet and flows through China, Bhutan, India, and Bangladesh before merging with the Ganges in the Bay of Bengal. The Medog Hydropower Station is strategically located at the Great Bend, where the river’s dramatic drop allows the generation of substantial energy. China promotes this dam as part of its green energy transition, aiming to reduce reliance on coal and bolster its climate goals.
Journalist Kunda Dixit from Kathmandu, who teaches climate communications, highlighted the potential regional impacts of the dam. He noted that while the dam might not be ecologically harmful compared to coal plants, its broader implications on the riverine ecosystem and the use of generated energy raise concerns. Dixit questioned whether the energy would feed consumerism and endless economic growth, which contributed to current environmental challenges.
China’s narrative on the Yarlung Tsangpo Dam emphasizes its hydropower potential, framing it as an ideal site for development. State media highlights that the project could significantly reduce coal consumption and CO2 emissions, contributing to global carbon neutrality goals. The dam is presented as part of a national strategy to supply clean energy to eastern industrial zones, enhance energy autonomy, and stimulate Tibet’s economic growth.
Indian concerns, however, focus on the strategic threat posed by China’s control over water flow. The Indian government and experts highlight potential geopolitical implications, fearing that the dam could undermine India’s security and regional influence. Beijing-aligned sources argue that India’s objections are geopolitically motivated, pointing to India’s resistance to infrastructure developments by China in neighboring countries.
The Chinese Foreign Ministry reiterates that the project has undergone rigorous scientific assessment, asserting no adverse impact on downstream countries. They emphasize the dam’s role in disaster prevention, mitigation, and climate change adaptation downstream, countering Indian allegations of ecological harm.
