On China’s Yangtze River, giant dam’s legacy blocks revival

By David Stanway  /  Reuters, CHONGQING, China

The 2,000 residents of Muhe, whose village was moved to higher ground a decade ago to escape the rising Yangtze River, have tried to make the most of their remaining land by planting orchards of oranges and persimmons along its banks.

With just 110 hectares on the edge of Asia’s longest river, Muhe lost half its territory to make way for the colossal Three Gorges Project, a 185m dam and 660km reservoir designed to control flooding, aid navigation and generate electricity.

Beijing has allocated more than 600 billion yuan (US$85.6 billion) since 2011 to alleviate the dam’s long-term effect on villages such as Muhe and bring the region’s deteriorating environment under “effective control.”

Yet many problems are still unresolved, and the government has promised to spend another 600 billion yuan by 2025, said Xie Deti (謝德體), a member of the Chongqing delegation of the National People’s Congress who lobbied the government to release more funds in March.

Protecting the Yangtze has become a priority for Beijing after Chinese President Xi Jinping (習近平) promised to end big and “destructive” development along the river, which stretches 6,000km from Tibet to Shanghai, supplies water to 400 million people and irrigates one-quarter of the country’s arable land.

Since Xi’s orders in 2016, local governments have dismantled dams, dredged plastic junk from the water, relocated factories, banned waste discharge and restricted farming and construction along the river.

“You can say we have undergone earth-shattering changes, especially when it comes to increasing our awareness of environmental protection,” said Liu Jiaqi, the Chinese Communist Party secretary in Muhe.

However, the region has been unable to evade the earth-shattering effect of the dam itself, which sits near two fault lines and has been blamed for a surge in earthquakes and the fragmentation of ecosystems, among myriad other problems.

The region saw as many as 776 earthquakes in 2017, 60 percent more than a year earlier, with the highest magnitude being 5, the Chinese Ministry of Ecology and Environment said.

The total number has risen significantly since the project began, with one study from the China Earthquake Administration showing a 30-fold increase between 2003 and 2009, when the reservoir was filled.

Xie, who is also a professor at Chongqing’s Southwest University, said that other challenges include algae blooms caused by fertilizer, and wastewater from tributaries polluting the river.

The government has long insisted the benefits of the dam outweigh the costs and disruptions, but in 2011, Beijing promised to spend 1,238 billion yuan by next year to try to fix them.

It pledged to raise living standards, heal the environment and create a long-term mechanism to prevent geological disasters.

However, less than half of the money had been spent by the end of last year, Xie said, adding that he had received assurances from Beijing that the rest would come between next year and 2025.

So far, farmland has been restored by dredging up submerged soil. Riverbanks have been strengthened and reforested to reduce landslide risks, and “ecological barrier zones” have been built along vulnerable parts of the river.

Yet one government scholar, who did not want to be named because of the sensitivity of the issue, said that the additional funding might not be enough to solve long-term problems.
