Scientists question environmental impact of China’s Winter Olympics bid

According to Beijing’s bid to hold the 2022 Winter Olympic Games, the environmental impact of the Games will be “ecofriendly” and “sustainable”. Experts say otherwise: providing snow for events will be tough in a city where “it just doesn’t snow” and “a Martian-like plan” will be needed to create artificial cover. Conservationists worry about moves to build Olympic ski resorts in national parks and protected nature reserves. Ski resorts, meanwhile, require water and lots of it but Beijing doesn’t have water.

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.

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.
