China to construct world’s largest hydroelectric dam in Tibet

China has permitted the development of what would be the world’s largest hydroelectric dam, stoking considerations concerning the displacement of communities in Tibet and downstream environmental impacts in India and Bangladesh.

The dam, which will likely be situated within the decrease reaches of the Yarlung Tsangpo River, might generate thrice extra energy than the Three Gorges Dam, at present the world’s largest hydroelectric plant.

Chinese language state media described the challenge as “a secure challenge that prioritizes ecological safety”, saying it should increase native prosperity and contribute to Beijing’s local weather neutrality targets.

Human rights teams and specialists, nevertheless, have expressed considerations concerning the knock-on results of this improvement.

Amongst them are fears that the development of the dam – first introduced in late 2020 – might displace native communities, considerably alter the pure panorama and harm native ecosystems, that are among the many richest and most various on the Tibetan Plateau.

China has constructed a number of dams in Tibetan areas – a controversial situation in a area intently managed by Beijing since its annexation within the Nineteen Fifties.

Activists have beforehand instructed the BBC that the dams are the newest instance of Beijing’s exploitation of Tibetans and their land. Tibet, which is predominantly Buddhist, has seen waves of repression through the years, throughout which 1000’s of persons are believed to have been killed.

Earlier this 12 months, the Chinese language authorities arrested lots of of Tibetans protesting one other hydroelectric dam. This resulted in arrests and beatings, with some folks critically injured. The BBC learned from verified sources and footage.

They’d opposed plans to construct the Gangtuo dam and hydroelectric energy station, which might displace a number of villages and submerge historical monasteries full of sacred relics. Beijing, nevertheless, mentioned it had relocated and compensated the residents, and put the traditional murals in a secure place.

Within the case of the Yarlung Tsangpo Dam, Chinese language authorities have careworn that the challenge wouldn’t have a serious environmental affect, however haven’t indicated how many individuals it could displace. The Three Gorges hydroelectric dam required the resettlement of 1.4 million folks.

Experiences point out that the colossal improvement would require drilling no less than 4 20km-long tunnels by the Namcha Barwa mountain, thereby diverting the circulation of the Yarlung Tsangpo, Tibet’s longest river.

Consultants and officers have additionally raised considerations that the dam would enable China to manage or divert the circulation of the cross-border river, which flows south into the Indian states of Arunachal Pradesh and India. ‘Assam, then to Bangladesh.

A 2020 report launched by the Lowy Institute, an Australia-based assume tank, famous that “management of those rivers [in the Tibetan Plateau] successfully offers China a stranglehold on the Indian financial system.”

Shortly after China introduced plans for the Yarlung Tsangpo Dam challenge in 2020, a senior Indian authorities official instructed Reuters that the Indian authorities was finding out the event of a giant hydroelectric dam and reservoir “to mitigate the unfavourable affect of Chinese language dam tasks”.

China’s International Ministry has beforehand responded to India’s considerations over the proposed dam, saying in 2020 that China had a “legit proper” to construct a dam on the river and had thought-about downstream impacts.

China has constructed a number of hydroelectric crops alongside the course of the Yarlung Tsangpo over the previous decade in an effort to harness the river’s energy as a renewable vitality supply. Operating by the deepest canyon on the planet, a bit of the river drops 2,000 meters in a brief distance of simply 50 km, providing huge potential for hydroelectricity era.

Nonetheless, the river’s dramatic topography additionally poses main engineering challenges – and this newest dam is by far China’s largest and most bold thus far.

The event web site is situated alongside an earthquake-prone tectonic plate boundary. Chinese language researchers additionally raised considerations that such intensive excavation and building within the steep and slim gorge would improve the frequency of landslides.

“Landslides and mudslides attributable to earthquakes are sometimes uncontrollable and also will pose an enormous menace to the challenge,” mentioned a senior engineer from the Sichuan provincial geological bureau in 2022.

The challenge might value as much as a trillion yuan ($127 billion; £109.3 billion) in keeping with estimates by the Chongyi Water Assets Bureau.
