A growing movement is reshaping the future of ocean governance by centering Indigenous knowledge systems, laws, and leadership in how the world cares for marine environments. As climate change accelerates and ocean ecosystems face increasing threats from pollution, overfishing, and deep-sea mining, Indigenous communities are working to assert their sovereign rights and responsibilities over the waters they have stewarded for thousands of years.

This movement envisions the creation of an “Indigenous Law of the Sea” — a framework rooted in ancestral teachings, relationships with marine life, and intergenerational stewardship. Unlike international maritime law, such as the United Nations Convention on the Law of the Sea (UNCLOS), which governs ocean use through the lens of state sovereignty and national borders, Indigenous law offers a fundamentally different approach. It prioritizes reciprocity, balance, and respect for the ocean as a living relative rather than a resource to be extracted.

Historically, international treaties have excluded Indigenous peoples, recognizing only nation-states as legitimate participants. This structure has left Indigenous communities without a formal voice in decisions that directly impact their ocean territories and ways of life. Yet despite being sidelined in global negotiations, Indigenous peoples have continued to uphold their legal and cultural responsibilities to protect the sea — responsibilities embedded in their stories, ceremonies, and everyday practices.

Indigenous law is not a theoretical concept but a lived reality. In many coastal and Arctic communities, protocols for engaging with the ocean are deeply ingrained. From seasonal harvesting rules to spiritual taboos, these laws have sustained marine ecosystems and Indigenous lifeways for millennia. Recent archaeological evidence confirms these long-standing relationships, demonstrating that Indigenous diets and practices have remained connected to ocean species for over 10,000 years.

But those relationships are under growing pressure. Climate change is rapidly transforming Arctic and sub-Arctic ecosystems. Glaciers are retreating at an alarming rate, destabilizing river systems that rely on seasonal meltwater. Warmer ocean temperatures are bringing new species into traditional waters, while vital ones — such as wild salmon and seaweed — are disappearing. Many Indigenous communities have been unable to harvest salmon for several years, not because of tradition but because of collapse. These changes threaten not just food security but the continuity of cultural knowledge and governance.

In response, Indigenous leaders and communities are coming together to define and assert their own legal frameworks for the ocean — not as a replacement for international law, but as a powerful complement. The goal is not to mimic existing treaties with different language, but to share a distinct set of principles: how to live in balance with the ocean, how to treat marine life with dignity, and how to sustain these relationships across generations.

These conversations are gaining momentum. Indigenous gatherings across the Pacific, Arctic, and Atlantic regions have begun creating spaces where communities can share stories, protocols, and legal principles. Some nations, such as those in Aotearoa New Zealand, have already developed their own Indigenous Law of the Sea, serving as catalysts for others. An informal alliance is forming among Indigenous peoples globally to discuss how these teachings can be compiled, shared, and presented to the world as a unified vision of ocean stewardship.

This movement is also about reclaiming space — creating tables where Indigenous peoples lead the conversation, rather than being added as an afterthought. It’s a declaration of inherent sovereignty: that Indigenous peoples have always had laws, governments, and responsibilities in place to protect the ocean, long before the arrival of colonial states or international treaties.

Crucially, participation in this movement does not require formal titles, fluency in traditional language, or academic credentials. Those who live close to the water, fish with care, and pass down ocean knowledge through generations are already practicing this law. The vision for an Indigenous Law of the Sea is inclusive — drawing strength from lived experience, community memory, and cultural resilience.

As the world grapples with environmental crises and increasingly unstable oceans, Indigenous law offers not only a path to sustainability but a model of relationship. It is a reminder that governance can be about responsibility, not control — and that the future of the ocean may depend on listening to those who have always known how to care for it.
