Native environmental sovereignty is a concept and interdisciplinary research field examining the inherent right and capacity of Indigenous peoples to govern, manage, and protect their traditional lands, territories, and natural resources according to their own laws, customs, and worldviews. It investigates the historical, legal, political, and ecological dimensions of Indigenous jurisdiction, emphasizing self-determination, the integration of traditional ecological knowledge, and the assertion of control over environments often impacted by colonial legacies and external exploitation. This concept is significant for understanding Indigenous rights, environmental justice, and alternative models of sustainable governance grounded in long-term relationships with place.
