The Three Gorges dam: a worrying precedent
The “Bringing the Yangtze to help the Han River” canal project is needed because of a much larger project, 250km to the north, that cuts the flow of the Han, a Yangtze tributary. About a quarter of the water in the Han will be reallocated to arid northern China in a $60bn engineering effort that critics say will create shortages in the south.
Last year, for the first time in 140m years, the Chinese sturgeon failed to breed in the wild.
The danger to the sturgeon was one risk cited by opponents to the world’s largest hydropower project, the $26bn Three Gorges dam, whose approval in 1992 kicked off two decades of construction of mega-dams in China. Hydropower now accounts for 23 per cent of China’s installed generation capacity and the companies that cut their teeth on the Three Gorges project are now the world’s premier dam-builders.
Along the Yangtze, the world’s third-longest river that cuts through central China like a muddy highway, the costs of the dam are just beginning to be totted up. A landslide wiped out a power substation on the reservoir this summer, while the 1,300km stretch of water below the dam regularly experiences low levels that may be exacerbated by the separate project to divert water north. “Dam refugees” can be found in the slums of Shanghai and other eastern cities, after resettlement programmes proved inadequate and riddled with graft.
Senior officials responsible for the dam were reshuffled during China’s anti-corruption campaign, in a rare acknowledgement by Beijing of the problems that have plagued the project.
