Rousseff's administration pushed to complete a number of hydroelectric dam projects in the Amazon River Basin, despite appeals from local residents of areas that would be affected, including indigenous tribes, and pressure from both domestic and international groups. Opposition to the dam projects, especially the Belo Monte Dam project, was driven by environmental, economic and human rights concerns, for both the people to be displaced and the workers brought in from other parts of Brazil to build the dams. Xingu (Kayapo) Chief Raoni Metuktire and members of other tribes affected by hydroelectric dam projects proposed or already under construction; Brazilian and international NGOs, including Greenpeace, Amazon Watch and International Rivers and international celebrities including director James Cameron, actress Sigourney Weaver, and musician Sting all called for a halt to Amazon Basin hydroelectric projects.
