Sometimes human rights abuses occur when the need to strengthen economies in developing nations clashes with the need to preserve traditional livelihoods for their citizens.

In Brazil's Belo Monte dam project, tens of thousands of indigenous people could lose their homelands in the Amazon so that the government can increase the growing nation's electricity output.

But whose concerns should take priority in these kinds of cases?

International campaigners say new global approaches must be designed to address complex human rights dilemmas.

Joining Riz to discuss these issues are James Cameron, the director of the block-buster movie Avatar, which highlights the environmental and human rights of indigenous people, the Duchess of York, Sarah Ferguson, who is one of the organisers of the Oslo Freedom Forum conference, and Thor Halvorssen, the founder of the conference, as well as a film producer and president of the Human Rights Foundation.
