Brahmaputra: China plans to divert Brahmaputra waters to its Xinjiang region through 1,000-km long tunnel
BEIJING: China’s prime management is contemplating digging a 1,000-km lengthy tunnel, which if accomplished could be the world’s longest by an enormous margin, to divert the waters of the Brahmaputra from Tibet to its dry Xinjiang area.
The Brahmaputra, known as the Yarlung Tsangpo in China, originates in Tibet and flows downstream into India’s northeast and sustains hundreds of thousands of individuals in its basin flowing into Bangladesh earlier than assembly the Bay of Bengal.
As soon as the tunnel is accepted, it would more than likely have an effect on the water move within the Brahmaputra, that might trigger draughts which have up to now been unusual within the river basin, because it’s extra susceptible to floods. Observers mentioned storing huge portions of water previous to dispatch by means of the tunnels might additionally enhance the dangers of flooding downstream.
The plan includes diverting water from Sangri county in Tibet to the Taklamakan desert in Xinjiang. The South China Morning Submit in Hong Kong quoted Chinese language engineers as saying that the plan has been submitted to increased authorities for approval by March 2018.
“An vital issue holding up approval for the big mission is the environmental dangers concerned in reducing by means of fragile mountains,” an engineer hooked up to Chinese language authorities mentioned. One other issue may very well be the excessive price concerned.
One Chinese language skilled, Wang Wei, who works for the State Key Laboratory of Hydraulics and Mountain River Engineering at Sichuan College, estimated that the associated fee could be one billion Yuan (roughly $ 150 million) per km of the tunnel. This might imply an total price of round $150 billion.
China had assured India in 2010 that it had no plans of constructing upstream dams in Zangmu in Tibet after New Delhi expressed issues about the identical. Beijing had mentioned that it was merely constructing run-of-the-river dam for hydroelectricity and that there was no want for it to carry huge portions of water that might endanger downstream areas in India.
The water diversion mission, if accepted, would imply China’s going again on its assurances.
Observers right here mentioned China may weigh in in favour of the mission if it serves
its strategic pursuits+
, which embody pressuring India. It has already dedicated $60 billion for the
China-Pakistan Financial Hall+
, which, consultants say, has extra strategic worth than financial price for Beijing.
“To my information, no environmental analysis has been carried out. The character and scale of the affect stay in the dead of night,” Zhou Shiqiao, a researcher on the Chinese language Academy of Sciences’ Institute of Tibetan Plateau Analysis in Beijing, instructed TOI.
One other researcher, Zhang Chuanqing, mentioned Beijing “would undoubtedly go forward with the mission in the future”.
“In 5 to 10 years, the expertise can be prepared and the associated fee reasonably priced, and the temptation of the advantages can be tough to withstand,” mentioned Zhang Chuanqing, a researcher on the Chinese language Academy of Sciences’ Institute of Rock and Soil Mechanics in Wuhan, who’s concerned in growing one other plan for a 600-km lengthy tunnel in Yunnan.
