Small dams an even bigger dam problem, say researchers

(June 1, 2013) New research from Oregon State University reveals small dams are no easier on the environment than their larger counterparts and often present more of a threat to their surroundings. The comparison between 31 small dams built on tributaries to China’s Nu River and four large dams proposed for the main stem of the same river, found the effects of the smaller dams were worse for nine out of the 14 characteristics studied. Habitat loss and damage at several dam sites show that the environmental effects of small dams are often greater, sometimes by several orders of magnitude. “A lack of regulation paired with a dearth of communication between small dam projects in China allows for the effects to multiply and accumulate through several dam sites,” say researchers.

Flow test for water project gets underway

(May 31, 2013) The process of diverting water from the Yangtze River through the eastern route of China’s massive South-to-North Water Diversion Project began this week after 11 years since construction began. Although the water diversion intended for drought-prone cities in China’s arid northern regions “will enrich the water supply in the north, its impact on the ecosystem is irreversible,” said Ma Jun, an environmentalist.

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.”

China’s new dawn

(May 24, 2013) The new dawn of Chinese activism: organic, leaderless and technology-driven. This report by journalist Monica Tan looks at the rise of public protest in China, how activism has moved away from a select high-profile few to become a growing movement made up of ordinary people – ‘lao baixing’ – determined to stand up for their environment. Technology enables large masses of people to get the word out and to assemble at low risk: no one and everyone leads. Some see this grassroots’ movement as the road to democracy and accountability for China.

The landslide story

(May 22, 2013) Chinese experts in landslide and geohazard protection fear debris flows, triggered by an epic 2008 earthquake in Sichuan Province, may pose a threat to the region for two decades. A tremendous amount of loose material from the landslides is suspended on hillslopes, ready to be washed away by rain. The potential for ongoing landslides and secondary hazards, such as flooding and blocked rivers, they argue, warrants further investigation.

Never-ending, hidden rules

Famed Chinese journalist and environmentalist Dai Qing, on her 70th birthday, reflects on the words of Confucius, who said: “When you’re 70, do as you please, as long as it doesn’t break the rules.” Dai, however, decides she was born 2,500 years too late. “I embody the cultural atmosphere of the ‘People’s Republic,'” she says. “With all its hidden rules.”

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.
