In China, and elsewhere, long-term economic development and poverty alleviation need to be balanced against the likelihood of ecological failure. Here, we show how paleoenvironmental records can provide important multidecadal perspectives on ecosystem services (ES). More than 50 different paleoenvironmental proxy records can be mapped to a wide range of ES categories and subcategories. Lake sediments are particularly suitable for reconstructing records of regulating services, such as soil stability, sediment regulation, and water purification, which are often less well monitored.

China's Three Gorges Corp. on Thursday marked the beginning of construction for a dam that will flood the last free-flowing portion of the middle reaches of the Yangtze, the country's longest river.

The 30 billion yuan ($4.75 billion) Xiaonanhai dam is decried by environmentalists because it will flood a nature reserve designed to protect about 40 species of river fish.

The uncertainty associated with predicting extreme weather events has serious implications for the developing world, owing to the greater societal vulnerability to such events. Continual exposure to unanticipated extreme events is a contributing factor for the descent into perpetual and structural rural poverty. We provide two examples of how probabilistic environmental prediction of extreme weather events can support dynamic adaptation. In the current climate era, we describe how short-term flood forecasts have been developed and implemented in Bangladesh.

Have you heard of the Yangtze River Dolphin? For the longest time, it used to be found along 1,700 kilometres of the middle and lower reaches of the mighty Chinese river. The Baiji, as it is known, was white finned, a little over two metres long, had poor eyesight and relied mainly on sonar for navigation. A few decades ago, as populations along the river grew, as shipping traffic rose, as more and more dams fragmenting the Baiji's habitat came up, as fishing by increasingly impoverished Chinese intensified, Baiji numbers began to crash.

China's landmark Three Gorges Dam project provides benefits to the Chinese people, but has created a myriad of urgent problems from the relocation of more than a million residents to risks of geological disasters, the Chinese government said on Thursday.

The statement from China's State Council, or cabinet, marked a rare acknowledgment of the issues that have shadowed the world's largest dam, a

Although reliable figures are often missing, considerable detrimental changes due to shrinking glaciers are universally expected for water availability in river systems under the influence of ongoing global climate change. We estimate the contribution potential of seasonally delayed glacier melt water to total water availability in large river systems.

Oslo: The world

The world's rivers are in crisis including in North America and Europe where governments have invested trillions of dollars to clean up freshwater supplies, a study showed Wednesday.

"Threats to human water security and biological diversity are pandemic," Charles Vorosmarty of the City University of New York, co-lead author of the report in the journal Nature, told Reuters.

The Himalayan glaciers that feed Asia's five largest rivers are in no danger of disappearing by 2035, as claimed in the Intergovernmental Panel on Climate Change's most recent report. In fact, only the glaciers that melt into the Ganges are shrinking, according to the most detailed analysis yet of how climate change will affect key Asian glaciers.
