The World Commission on Dams, a commission created by the World Bank, has been asked to review some major dam projects from around the world. The Three Gorges Dam (TGD) on the Yangtze River is the focus of one of the case studies and will be reviewed for the social, economic and environmental costs and benefits. The commission plans to investigate the pros and cons of building the TGD.
