Three Gorges Dam 'could be huge disaster'
September 27, 2007


SENIOR Chinese officials have admitted the Three Gorges Dam is at risk of 
becoming a "catastrophic" environmental disaster if accumulating threats are 
not dealt with promptly.

Those officials, who previously defended the world's biggest hydropower project 
as an engineering and economic miracle, spoke at a forum organised by the State 
Council, China's cabinet, on Tuesday in Wuhan.

The forum, called to discuss the dam's spiralling environmental problems, 
concluded that if no preventive measures were taken, the project could lead to 
catastrophe, China's official news agency, Xinhua, reported.

The director of the Government's Three Gorges construction body, Wang Xiaofeng, 
told the forum that Beijing had largely overcome many challenges to the dam 
project - including funding, technology and the massive displacement of people 
- but it now had to face up to the increasing ecological threats.

These included erosion and landslides, pollution and "ecological deterioration" 
caused by "irrational development" along the river, he said.

"We absolutely cannot relax our guard against ecological and environmental 
security problems created by the Three Gorges project," Mr Wang said.

Since building the $A28.6 billion dam began almost two decades ago, officials 
have promoted it as a way to provide clean energy, create jobs and development 
and mitigate deadly floods along the mighty Yangtze River.

Critics have claimed that the giant concrete barrier retains huge amounts of 
sediment and nutrients, reducing fish stocks and viability of farmland 
downstream as well as creating greater instability in an already geologically 
unstable region.

A senior engineer at the forum also expressed concerns about landslides 
threatening the densely populated hills along the river. "Regular geological 
disasters are a severe threat to the lives of residents around the dam," Huang 
Xuebin said.

He described landslides into the dam waters creating waves dozens of metres 
high that then crashed into surrounding shores, creating more damage.

Local officials reported that water quality in tributaries of the Yangtze had 
declined and pollution caused by sediment build-up had increased algae in local 
rivers.

Last month experts partly blamed the Three Gorges Dam for declining water 
quality in China's largest freshwater lake, the Poyang.

Xinhua also released a separate, positive report on the forum, headlined "Three 
Gorges environment and construction progressing well". The negative article was 
headlined "Three Gorges faces many environmental problems".

The People's Daily, the Communist Party's flagship newspaper, yesterday ran the 
positive version of the story.

The good news was that tensions among residents who had been resettled had 
eased and water quality in the dam was "generally stable".

Xinhua also reported that tens of billions of yuan had been spent to prevent 
pollution and geological disasters by tree planting, measures to maintain 
species diversification, shutting 1500 polluting industrial and mining 
enterprises and building 70 sewage and waste treatment plants.
