(October 21, 2013) Scientists are using medical technology to study the endangered Yangtze finless porpoise and their critical sense of hearing, used for navigation, to understand how these mammals are managing in the very busy and loud waters of China’s high-traffic Yangtze River. “In a noisy environment, they’d have a hard time hearing their prey or their friend. It makes it more difficult for them to conduct basic biological activities such as foraging, communicating, and navigating in the river,” said biologist and lead author of the survey, Aran Mooney.
All dried up
(October 12, 2013) This Economist report looks at the gravity of China’s water crisis, once summed up by Wang Shucheng, a former water minister as: “To fight for every drop of water or die: that is the challenge facing China.”
Deng Xiaoping’s double debt to the Chinese people
(September 10, 2013) On the dreadful night of June 4, 1989, when the students in Tiananmen Square were mowed down by the People’s Liberation Army, the path to another tragedy, the damming of the Yangtze, was laid, says Dai Qing, China’s most famous environmentalist and longtime advocate of freedom of speech.
Has the Three Gorges Dam increased Shanghai’s flood risk potential?
(August 9, 2013) The effects of the giant dam’s operations on water flow are ramping up the risks of damage from storm surges in Shanghai, says expert. Meanwhile, China’s flood loss potential sounds warning bells for insurers.
Giant landslide likely caused by Xiluodu Dam impoundment, says Chinese geologist
(July 30, 2013) Fan Xiao, a Chinese geologist and chief engineer of the Regional Geological Survey Team of the Sichuan Geology and Mineral Bureau, says analysis of the recent landslide in Yunnan Province indicates that impoundment of the nearby Xiluodu Dam reservoir most likely caused the event and that more can be expected when the reservoir is filled again. Sharply rising or rapidly falling reservoir water levels pose a threat to geological stability, he says, and can trigger disaster.
Three Gorges Dam trashes Yangtze, images show
(July 19, 2013) Images show the ugly side of China’s grand dam and its effects on the country’s beloved Yangtze River: rubbish crusts, floating islands of garbage — a plague of filth and issues that exacerbate existing problems and introduce new dangers. Policymic.com reports.
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.”
Small dam construction to reduce greenhouse emissions is causing ecosystem disruption
(June 20, 2013) A new report says the global push to reduce greenhouse gases by building small dams, with the help of the Kyoto Protocol, is causing unanticipated and potentially significant losses to habitat and biodiversity.
Officials from China’s Three Gorges Corporation visit troubled U.S. lock
(June 19, 2013) Officials from China’s Three Gorges Corporation and Project Construction Committee (TGPCC) paid a visit earlier this month to the troubled U.S. Chickamauga Lock in Tennessee as part of an information sharing exchange organized by the U.S. Army Corps of Engineers (USACE) — responsible for the operation and maintenance of navigation locks on the Tennessee River. TGPCC, established by China’s State Council to oversee construction of the massive Three Gorges Dam project, has concerns regarding its own ship locks: some 733 cracks were reported to have appeared in the east and westbound channels of the Three Gorges dam’s five-step shiplock, along with a worrisome distortion that may have been caused by crustal plate movement, among other issues. The dam’s ambitious and intensely complex ship lift, slated for completion in 2015, has yet to be tested.
Uprooted
(June 14, 2013) Yang Yi’s surreal photo memoir of his childhood home, flooded for the construction of China’s Three Gorges Dam project, received special mention as one of New York’s Best Weekend Art Events in May when it debuted at Galerie Richard. Its run ends tomorrow, June 15.
The problem with environmental impact assessments – continued
(June 3, 2013) News that an environmental impact assessment (EIA) for China’s tallest dam was approved last month by the Ministry of Environmental Protection is a signal that developers and politicians in China understand well the green-washing power of EIAs to move forward destructive projects.
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.
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.”
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.
China earthquake points to future risk sites
(April 30, 2013) Nature magazine reports that, while scientists agree that China’s deadly tremor at Ya’an (Lushan county) may hint at where future quakes will strike, they disagree on which seismic fault the next rupture is likely to occur.
