Solomon Islands, Vanuatu, Papua New Guinea, and New Caledonia are establishing the world’s first multinational Indigenous marine reserve across six million square kilometers of ocean grounded in ancestral stewardship.
For thousands of years, the ocean has been a highway, a pantry, a classroom, and a sacred space for Melanesia’s Indigenous peoples. It carries the stories of ancestors and the dreams of children. It is where identities are anchored, and sovereignty begins. Now, the governments of these ocean nations are transforming that ancestral relationship into the largest interconnected marine protection framework on Earth.
Announced at the 2025 UN Ocean Conference in Nice, France, the Melanesian Ocean Reserve will operate across the Exclusive Economic Zones of the Solomon Islands, Vanuatu, Papua New Guinea, and New Caledonia. The multinational Indigenous marine reserve permits only sustainable economic activities consistent with Indigenous values in these waters, protecting one of the world’s richest marine biodiversity regions, which hosts an estimated 75% of known coral species and more than 3,000 reef-associated fish species.
The vision emerged during the 2024 Convention on Biological Diversity in Cali, Colombia, when two respected Indigenous leaders met for the first time. Solomon Islands’ Minister for Environment, Trevor Mahaga, and Vanuatu’s Minister for Environment, Ralph Regenvanu, began sketching the blueprint and later refined it with Papua New Guinea’s Minister of Fisheries, Jelta Wong. New Caledonia’s environment minister, Jeremie Katidjo Monnier, subsequently announced support at the UN Ocean Conference.
Solomon Islands Prime Minister Jeremiah Manele framed the multinational Indigenous marine reserve as part of millennia of ocean stewardship, explaining that Melanesian governments are joining forces to create an unprecedented reserve honoring identities, livelihoods, and spiritual connections that have sustained these communities since humans first navigated these waters over 30,000 years ago.
The reserve is premised on a fundamental concept: these waters are the home of Indigenous peoples who have occupied them for hundreds of centuries, and their continued harmonious presence offers the best long-term security. This isn’t symbolic inclusion. The only Cabinet-endorsed ocean governance framework currently being advanced by the Solomon Islands government, the multinational Indigenous marine reserve, is already being actively implemented and is delivering outcomes across ocean governance, conservation, and sustainable development.
The Islands Knowledge Institute, an Indigenous-led organization in the Solomon Islands led by ecologist Dr. Edgar Pollard, has been the primary incubator of the initiative. Pollard described the reserve as connecting to an unmistakable truth in Melanesian leaders’ lives: that treating the ocean as home in the deepest sense offers the best protection. The excitement stems from making this relationship real at every level, from the tribe to the village to the state.
Implementation operates through four programs. ARA establishes ocean knowledge partnerships integrating cultural knowledge with scientific approaches. VATA (Voyaging, Alliance, Trade, and Autonomy) addresses voyaging, alliance, trade, and autonomy. SOLWATA (Seascape Oversight and Local Watch) provides seascape oversight and local watch through community-led surveillance. MANA creates an Indigenous investment platform channeling resources toward sustainable development.
The multinational Indigenous marine reserve builds on a no-loss principle protecting key revenue sources while creating new pathways for investment. Implementation spans eco-tourism, small-scale Indigenous fisheries, sustainable aquaculture, and renewable ocean energy. Marine governance flows from ancestral wisdom through these practical programs, ensuring livelihoods and ecosystems grow together rather than compete.

Ministerial-level leadership from all participating countries has strengthened regional momentum. At the Pacific Islands Forum in Honiara in September 2025, Solomon Islands’ ministers for fisheries and environment provided updates on the establishment of the reserve, confirming the government’s continued commitment beyond the initial announcement.
The Melanesian region faces serious threats despite its ecological richness. Illegal fishing vessels steal from territorial seas daily. Climate change threatens coral systems and coastal communities. Papua New Guinea’s controversial deep-sea mining plans raise questions about how to reconcile extractive industries with the conservation goals of the multinational Indigenous marine reserve, though proponents argue the framework provides precisely the governance structure needed to address such conflicts.
The reserve’s governance model distinguishes it from conventional marine protected areas imposed through external authority. Traditional customary law and Indigenous knowledge actively shape the implementation of ocean management. Communities that have navigated and cared for these waters for generations lead decision-making rather than receiving token consultation on plans designed elsewhere.
The multinational Indigenous marine reserve represents more than environmental protection. It is a living cultural seascape where children paddle through waters to reach schools, creating connections with the sea. Each wave carries lessons and values defining Melanesian life. By formalizing ancestral governance within modern legal frameworks, the reserve ensures these cultural relationships receive the same protection as ecological systems.
Vanuatu’s Minister Regenvanu emphasized the reserve’s global significance, hoping Indigenous stewardship of this vast area will create momentum for similar initiatives worldwide. The model demonstrates that ocean governance led by countries, grounded in national authority, and focused on implementation rather than declaration can achieve protection at scales that match the ocean’s interconnected systems.
The multinational Indigenous marine reserve stands as both a bold conservation effort and a powerful affirmation of Indigenous leadership in global ocean governance. As environmental challenges intensify across the Pacific, Melanesia’s approach, rooted in 30,000 years of ocean stewardship, endorsed by national cabinets, and implemented through Indigenous-led programs, offers a model that may reshape how humanity protects the waters sustaining life on Earth.
