of Country

There are more than 476 million Indigenous Peoples, found in all regions of the world, from the Arctic to the tropical forests. They make up more than 6 per cent of our global population.


In the spirit of reconciliation, EarthCheck acknowledge the Traditional Custodians of Country throughout the world and their connections to land, sea and community. We pay our respect to their Elders past and present and extend that respect to all Indigenous Peoples today.


EarthCheck acknowledges that Indigenous Peoples are guardians of the forests and biodiversity hotspots we all depend on. Research shows that lands managed by Indigenous Peoples, with secure rights, experience lower deforestation rates, store more carbon, hold more biodiversity, and benefit more people than other lands — including protected areas.


We recognise and support the United Nations Declaration on the Rights of Indigenous Peoples (UNDRIP), the most comprehensive international instrument on the rights of Indigenous Peoples. The Declaration is a positive document that maps out a path for Indigenous Peoples to be free from discrimination and secure in their identities and life choices.
