The United Nations has called for solidarity from world governments for Indigenous peoples over the militarisation of their traditional land and to better safeguard the environment.

UN independent expert on human rights and international solidarity, Cecilia Bailliet, has visited multiple Indigenous communities, including extensive time with the Inuit population in the Danish autonomous territory of Greenland, and a trip to speak to the diverse Amerindian tribes of Central and South America.

Ms Bailliet has since presented a report at the UN's New York headquarters on implementing a declaration over the rights of Indigenous peoples within its member statesm, on identifying good practices and addressing key challenges and issues.

She is asking for solidarity and peace from some of the world's most powerful countries to help eradicate the "normalisation of violence" over concerns of militarisation risks, highlighting a US presence in Greenland where 90 per cent of residents are Inuit, mostly from the Kalaallit tribe.

"This (report) is timely because we see a miltarisation of many territories of where Indigenous peoples live that includes the Arctic and right down to the Amazon," Ms Bailliet told the press conference.

"We are seeking recognition of the right of participation of Indigenous people in processes that would seek to preserve peaceful dispute resolutions to counter the threat of use of force within their territories of violence and destruction of their environment.

"Indigenous peoples have a solidarity perspective of their peoples to the environment, but also to other vulnerable groups such as minorities, refugees and migrants.

"The report highlights how Indigenous people speak to and protect the people who are seeking asylum as well as underscore the role of their Indigenous women."

Archaeological finds have linked Palaeo-Inuit cultures in Greenland for 4500 years until Norway ruled the land in 1262.

Greenlanders have held a form of home rule since 1979 and voted to approve a referendum for greater autonomy towards self-independence and possible independence in 2008, however Denmark maintains in full control over the territory's foreign affairs and defence matters.

Danish prime minister Mette Frederiksen came out this week with strident calls to strengthen defence which would involve Greenland's military presence, after once defending its colonisation against US president Donald Trump's interest in purchasing the territory which has remained in Denmark's hands since 1812.

Ms Bailliet said the UN would defend its solidarity principles for Inuit people while also ordering a clean-up of the "American military waste" on the back of consultation with the custodians of the land which would ensure their Indigenous voices are protected.

Another UN report released in April has found Indigenous people make up just six per cent of the global population, but they safeguard 80 per cent of the planet's remaining biodiversity – yet receive less than one per cent of international climate funding.

"In showing solidarity leadership, we are calling for an international solidarity global system, in which people from the north to the south, to the east to the west, will be given opportunities to exchange their knowledge and to promote a world view in accordance with the protection of their environment," Ms Bailliet said.

The State of the World's Indigenous Peoples report offered a sobering assessment of climate action which is not only lacking in urgency, but in fairness.

From green energy projects imposed without Indigenous consent to policy decisions which are made inside backrooms where periphery voices are absent, these communities are too often excluded from climate solutions and denied resources to lead the way.

Another bold plan proposed by the UN is to introduce Indigenous university campuses around the world, Ms Bailliet said.

"We seek support from Indigenous education – so we can welcome law schools from around the world to courses on Indigenous lore, and for the UN to discuss a possibility of creating a new Indigenous university where different Indigenous communities can come to share knowledge for dissemination," she said.
