Melanesian Nations Agree to Create World's Largest Transboundary Marine Protected Area
Papua New Guinea, Fiji, and Vanuatu have formed the Melanesian Ocean Corridor of Reserves (MOCOR) to connect and expand their marine protected areas. The initiative covers at least six million square kilometers, aiming to become the world’s largest transboundary marine protected area. Key Contributions and Commitments Announced at the inaugural Melanesian Ocean Summit in May 2026 in Port Moresby. Papua New Guinea: Commits the Western Manus Marine Protected Area in the Bismarck Sea, covering over 214,000 square kilometers (9% of its exclusive economic zone). Vanuatu: Pledges 70,000 square kilometers within the Torba National Marine Protected Area (10% of its exclusive economic zone). Fiji: Pledges 15% of its waters this year, with plans to expand further over the next five years. Objectives and Rationale Serves as a unified Pacific response to climate change, rising sea levels, and coral reef destruction. Acts as a platform for regional Melanesian integration, emphasizing stewardship that transcends national borders. Vanuatu Prime Minister Jotham Napat framed the move as choosing "protection over extraction." Caveats and Future Outlook The Pacific Network on Globalization has urged leaders to translate these regional commitments into binding domestic legislation, specifically calling for a moratorium on deep-sea mining. Enric Sala of National Geographic praised the commitment to protect 30% of critical marine biodiversity. Nations are scheduled to meet again in two years to review and broaden their protection commitments.
