WASHINGTON, D.C. Oct. 18, 2011 — According to Dr. Peter Gleick and his colleagues in the newest volume of the most important assessment of global water challenges and solutions, more and more regions of the world, including the United States, may be reaching the point of "peak water." To conserve this critical resource without harming the economy or public health, businesses, communities, governments, and individuals are looking for new techniques to move to sustainable water management.

The World's Water, Vol. 7 offers discussion and analysis for developing those reforms. For more than a decade, this biennial report has provided key data and expert insights into freshwater issues. In the seventh volume in the series, Gleick and his colleagues at the Pacific Institute address such issues as increased conflicts over water resources, "fracking" natural gas contamination, corporate risks and responsibilities around water, and the growing risks of climate change. They specifically explore:

Emerging insights from adaptive and community-based resource management suggest that building resilience into both human and ecological systems is an effective way to cope with environmental change characterized by future surprises or unknowable risks. In this paper, originally published in Ecology and Society, authors Emma Tompkins argue that these emerging insights have implications for policies and strategies for responding to climate change. The authors review perspectives on collective action for natural resource management to inform understanding of climate response capacity. They demonstrate the importance of social learning, specifically in relation to the acceptance of strategies that build social and ecological resilience. Societies and communities dependent on natural resources need to enhance their capacity to adapt to the impacts of future climate change, particularly when such impacts could lie outside their experienced coping range. This argument is illustrated by an example of present-day collective action for community-based coastal management in Trinidad and Tobago.

China and the Cascading Geopolitics of Lower Mekong Dams

Much has been written on the downstream impact of China’s dams on the Lancang-Mekong River, which flows through or along the borders of five other countries after exiting China.   Most of the discussion relates to the hydrological impact of impounding water in the eight dams along the mainstream Lancang Jiang in Yunnan Province.  Particular concern surrounds the recently completed Xiaowan Dam and the recently approved construction of the Nuozhadu Dam, each of which is of a scale to impound quantities of water that can affect river hydrology throughout the basin.  The Lancang Cascade, as it is termed, has caused considerable controversy in downstream countries, most notably during the 2008 floods and the 2010 drought.  Both the floods and the droughts were blamed by many in Thailand, and some in Laos, Cambodia and Vietnam, on China’s actions.  Recent articles on the downstream implications of altered river hydrology and the need for China to be less disingenuous in its public relations over the issue show the confluence of river hydrology and geopolitics in an international river basin such as the Lancang-Mekong.
