Indigenous Peoples have resiliently weathered continued assaults on their sovereignty and rights throughout colonialism and its continuing effects. Indigenous Peoples\' sovereignty has been strained by the increasing effects of global environmental change within their territories, including climate change and pollution, and by threats and impositions against their land and water rights. This continuing strain against sovereignty has prompted a call to action to conceptualise the determinants of planetary health from a perspective that embodied Indigenous-specific methods of knowledge gathering from around the globe. A group of Indigenous scholars, practitioners, land and water defenders, respected Elders, and knowledge-holders came together to define the determinants of planetary health from an Indigenous perspective. Three overarching levels of interconnected determinants, in addition to ten individual-level determinants, were identified as being integral to the health and sustainability of the planet, Mother Earth.
