New Research Finds 472 Million People Worldwide Have Potentially Been Negatively Affected by Dams
Published in a special issue of the Water Alternatives journal recognizing the 10th anniversary of the World Commission on Dams, the findings reveal that at least 472 million people have potentially experienced negative consequences to their incomes and livelihoods. "There are many places where dams have undeniably provided economic benefits such as flood protection, irrigation, and hydropower, but as this report shows they have also caused serious consequences for some of the world's most vulnerable people," said Brian Richter, The Nature Conservancy's Global Freshwater Program Director and lead author of the report. "At a time when global dam-building is rampant, we need to be smarter about planning for and operating dams in ways that alleviate harmful human and ecological impacts."... On the Kafue River in Zambia, 50 percent of the fish catch once consisted of the commercially-important three spotted tilapia, but after the Kafue Gorge and Itezhitezhi Dams were built, this figure was reduced to only 3 percent.... In the Mun River in Thailand, the Pak Mun Dam has caused a 60-80 percent decrease in fish catch, and 50 fish species have disappeared entirely.... The paperís authors point out that pragmatic, scientifically-sound and well-demonstrated approaches and solutions are already available and can be utilized today, not only at the dam planning phase but also retroactively, to adjust the operations of an existing dam. "It is unacceptable that half a billion people have been essentially ignored"....
