Seeing in the Dark: How porpoises hear in one of the world’s busiest rivers

(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.

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.

Climate change a dam smokescreen?

(November 20, 2012) Poyang, China’s largest freshwater lake, is experiencing a dramatic drop in water levels as a result of drought exacerbated by the effects of ongoing climate change — a dry-up that began in earnest in 2003, according to a report published by China’s state-run Xinhua news agency earlier this year. What the report doesn’t acknowledge is that 2003 also coincides with the year reservoir filling began at the Three Gorges mega-dam 500-km upstream of Poyang, on the Yangtze River. Responding separately to Xinhua’s claims, noted Chinese geologist and environmentalist Fan Xiao points to operations at the dam, as well as rapid development of the Yangtze’s upper reaches, as the culprits behind the distressing changes Poyang and other Yangtze tributaries are experiencing: expect worse, he warns, but not because of climate change.

Whitewashing the Three Gorges Dam

(October 15, 2012) Lauded by Chinese officialdom as a symbol of its growing might, the Three Gorges Dam had already been in operation for eight years when the Three Gorges Corporation issued its first-ever corporate social responsibility report. The release of the CSR report coincided with a wave of heightened concern surrounding the dam’s failings and impacts, and a rare admission by China’s State Council that all was not well with the jewel in its crown of modernity. A commentary by Li Tie at the time, published by China’s respected South Weekend, described the Corporation’s document as awash in insipid content” and exactly not what the public needed, which was honesty. Li even went so far as to say reports that did not respond honestly to widespread concerns, in effect, posed a threat to the nation’s social stability, leaving Chinese citizens more likely to place their faith in the country’s rumor mill than official documents they could not trust. Li’s misgivings appear to have only gained in resonance this year, as China’s recent summer of protest bears out.

Red Yangtze

(September 17, 2012) China’s famed golden waterway turns a disturbing red in the southwest region’s largest industrial centre. Speculation as to why runs the gamut from industrial dye dumps to an omen of biblical doom.

China’s new mega-dam is a mega-problem

(July 12, 2012) Almost 20 years in the making, China’s Three Gorges mega-dam was declared complete on July 4 when the last of its 32 generators went online, 10 years after the first turbine went into operation. There is no end in sight, however, for costs associated with the vast and controversial project, which remains closer to disaster than triumph.

A litany of troubles at Three Gorges Dam

To most observers, Chinese officialdom has supported the Three Gorges Dam without fail. But a closer look reveals growing worries about the dam which has become a symbol of all that is wrong with China’s rise. Here we present Chinese officials’ admissions of problems at Three Gorges, from the sensational mea culpas of senior officials to the subtly expressed worries of eminent scientists.
