He insisted their voices need to be heard “in every relevant national, regional and global conversation” and stressed the need to protect Indigenous human rights defenders from violence and reprisals.

Mr. Türk recalled the “profoundly moving” story of survival by four Huitoto children whose mother died when they were all in a plane crash in the Colombian rainforest last month. They were found alive after 40 days, including a one-year-old baby.

“The older children were able to hark back to the lessons of their mother and grandmother. They knew it was possible to understand the rainforest and to co-exist with its animals and plants, despite the risks.”

He said Indigenous people were most likely to carry the chain of culture forward: “We see this very clearly in the context of climate change”, with its unequal impact, often leaving those closest to the land, to experience the worst effects.

This is especially true for Indigenous women, he reminded, hit disproportionately by “climate damage and the unprincipled development of megaprojects.”

Meeting 45 Indigenous leaders from 30 countries just last week, the rights chief said climate change was referenced often. “As the ice melts, our culture and the way of living dies”, one participant from Greenland told him.

He said he hoped there would be increasing opportunities for Indigenous Peoples to participate at the UN, including in the Geneva-based Human Rights Council.

“Because you have a right to make your voices heard. Because you have the right to participate in decision-making in matters which would affect you, through representatives chosen by you according to your procedures. And because your voices are deeply valuable to every aspect of our work to advance human rights.”
