The World Bank has stepped in to help fund Uganda's Bujagali hydropower project after US power giant AES Corporation pulled out of the project, which is aimed at providing Uganda with a cheaper source of power. The $520m project at Bujagali on the Nile river ran into trouble after environmentalists argued that it would destroy a network of waterfalls, a major tourism attraction and water rafting site, and a site of special spiritual significance to the local population.
