Too many dams to look after

As China continues to embrace a new era of hydropower expansion, demand for dam inspection has outpaced the country’s supply of inspectors, ramping up safety fears for thousands of small- and medium-sized dams in China’s rural areas that have been “ignored”, reports Ecns.cn.

Brahma Chellaney: China’s dam boom stokes concerns in Asia

The need for China to enter into institutionalized water-sharing arrangements with its downstream neighbours is key to building water cooperation and the protection of critical ecosystems but its reluctance to do so, says geostrategist and author Brahma Chellaney, is to secure its monetary and political power as the controller of Asia’s major waters.

Chinese dam builders rush to Latin America

(January 7, 2014) China’s growing involvement in hydropower development in the region boosts clout but also leads to allegations of poor corporate responsibility. “There is great resistance to dam-building in Latin America and special worry about Chinese dams because of the opaque nature of China’s decision-making and poor quality in these dams,” says Pat Adams of Probe International.

Massive new dams remind China of human price of ‘tofu constructions’

(July 20, 2013) China is on the cusp of another dam-building binge. Nowhere is the aggressive dam push raising more eyebrows than in the country’s southwest. Last year, a report by the environmental group Probe International said of the 130 proposed dams on rivers in the region, nearly 50 per cent “are located in zones of high to very high seismic hazard.”

A decade on, controversy still surrounds China’s Three Gorges Dam

(May 31, 2013) Agence France-Presse reports that despite problems, China’s Three Gorges dam will be joined by a wave of new hydropower projects over the next decade — mostly spread across the country’s mountainous and earthquake prone southwest. The ambitious plans have left some in China’s growing environmental movement feeling powerless. Probe International Fellow, activist and journalist Dai Qing, who spent time in prison for her opposition to the Three Gorges dam, says the country’s environmentalists “continue to oppose the hydropower plans” but “they will be built no matter what local people say.”

Could dams be causing China’s earthquakes?

(April 24, 2013) Another article exploring the brewing debate over the cause or causes of the April 20 Lushan earthquake reports that the quake may have been an aftershock of Sichuan’s 2008 earthquake disaster, which some experts believe was triggered by the Zipingpu Dam reservoir. This issue of “reservoir-induced seismicity” is fast gaining attention as China, the most dammed nation in the world, is particularly at risk to the phenomenon. A 2011 Chinese study, for example, found China’s massive Three Gorges Dam had triggered around 3,000 earthquakes and numerous landslides in the reservoir region, representing a 30-fold increase in seismic activity in the area.

On alert: RIS risk amid rash of earthquakes in China’s Sichuan-Yunnan region

(March 22, 2013) A new report, exclusive to Probe International, calls for urgent monitoring of China’s large dams in areas prone to seismic hazard. These areas may be at increased risk from dam reservoir-induced seismicity (RIS). Scientists have observed that reservoir impoundment may not only increase the risk of strong earthquakes, particularly in areas already vulnerable to high-intensity seismic activity, but may represent a more pronounced risk in the first few years after a dam is filled.
