China dams on Brahmaputra pose huge ecological risk

The author of “Meltdown in Tibet” challenges China’s claims its cascade dams planned for the trans-boundary Brahmaputra River pose no impacts for downstream communities. “These dams are just the start of things,” he says. If all the proposed dams go into operation “the river will never be the same again”. Free Press Journal reports.

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.

New action guide targets Chinese dam construction

(November 29, 2012) As the most dammed country in the world and the largest exporter of dams abroad, China ranks as a hydropower-producing powerhouse with a wealth of experience that should inspire reassurance. The opposite is often the case, however, given China’s disregard for international social and environmental standards, both at home and overseas. A new action guide produced by the US-based environmental NGO, International Rivers Network, aims to help watchdogs of China’s ‘going out’ projects in their efforts to ensure safety and the rights of local communities affected by Chinese dam construction.

Mega-dams in China’s earthquake zones could have “disastrous consequences”

(October 31, 2012) “Earthquake Hazards and Large Dams in Western China,” the Probe International report authored by geologist John Jackson, has set China’s academic and industry circles astir. As the debate over Jackson’s findings heats up, the respected Caixin Media magazine, New Century Weekly, looks at both sides of the debate and the specific issues Jackson’s explosive report has raised.

China’s hydropower output drops

(October 20, 2011) Two recent reports show that China’s hydropower output has fallen drastically over the past year, as decreased runoff from major rivers has led to falling reservoir levels in China’s major dams. The Bureau of Statistics stated that hydropower output was one-fifth lower than last September, while the National Development and Reform Commission measured a decrease of 24.5% – a loss of nearly a quarter.
