Green groups condemn UN plan to use $136m from climate fund for large dams

An alliance of green groups have called out plans for UN-backed hydro projects in Nepal, Tajikistan and the Solomon Islands, saying they will have “tremendous negative impacts” on ecosystems and indigenous people. Touted as a renewable energy source, large dams account for up to a billion tonnes of greenhouse gases a year due to rotting vegetation in the water, say critics. The Guardian U.K. reports.

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.
