Sturgeons released

(August 7, 2006) Thousands of endangered Chinese sturgeons, equipped with microchips that will record migration patterns, have been released into the Yangtze River. Each fish also carries a tag with a phone number so that, if caught, it can be returned to scientists.

The heat is on for the ‘living fossil’

Despite its long lineage as one of the world’s oldest living species, the Chinese sturgeon — known as the “living fossil” because it dates back to the Cretaceous period — may not survive the surging dams and bridges built over the Yangtze River, reports China Daily.

Ten years of the Three Gorges Dam: a call for policy overhaul

An urgent overhaul of Three Gorges’ Dam management policy to enforce relevant regulations is needed to save various endangered species, improve the environment, and encourage economic development, say the authors of this paper. Xiankun Yang and X X Lu of the National University of Singapore discuss what we’ve learned from this controversial megadam over the past decade.

China’s great dam boom: A major assault on its rivers

(November 12, 2013) China’s current fever for hydro development is such that even its unparalleled Three Gorges mega-dam now ranks as a mere fraction of its long-term dam agenda, reports Charles Lewis for Yale Environment 360. While China’s need for energy is undisputed, its emphasis on dam construction risks an irreversible legacy of damage the country may never recover from and flies in the face of its present Five Year Plan to develop clean energy, reduce pollution, and protect the environment, says Lewis. Echoing Probe International’s coverage of the innumerable threats posed by construction on such an unprecedented scale, Lewis presents here a valuable and succinct overview of the dangers China’s dam fever represents to its waterways, ecosystems, agriculture and fisheries, traditional livelihoods, species survival and even to its geological stability, as Probe International’s alarming 2012 findings revealed.

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.

Dam madness

(July 4, 2012) As the fierce struggle between China’s hydropower industry and environmental conservationists rages anew, what has become clear in the meanwhile: the country’s rivers cannot sustain the current pace of development.
