West African nations have launched a coordinated effort to establish one of the world's first high-seas marine protected areas in the Eastern Atlantic, according to an initiative unveiled at the 11th Our Ocean Conference.

The proposal targets waters beyond national jurisdiction off the coasts of West Africa, a region rich in biodiversity but facing mounting pressure from industrial fishing, shipping, and resource extraction. High-seas areas remain largely unregulated because they fall outside any single nation's territorial control. The new push seeks to change that status by designating the Eastern Atlantic zone as a protected area with enforceable conservation rules.

This initiative follows the 2023 Agreement on Biodiversity Beyond National Jurisdiction, a landmark United Nations treaty that created legal mechanisms for establishing marine protected areas on the high seas. The agreement entered force in June 2024, opening pathways for governments to propose and govern ocean conservation zones in international waters.

West African governments see the Eastern Atlantic designation as a model for protecting fish stocks that support regional economies and food security for millions. Overfishing depletes these populations at unsustainable rates. Industrial vessels from distant-water fishing nations extract significant biomass from the region annually, often with limited monitoring or accountability.

Marine protected areas on the high seas function by restricting extractive activities, including fishing, mining, and oil drilling, across defined zones. They can remain open to scientific research and some sustainable use while preserving ecosystem functions. Scientists argue that protecting 30 percent of ocean area by 2030 provides critical buffers against warming-driven species loss and helps maintain ocean carbon cycling.

The Eastern Atlantic's designation would represent an early test of international ocean governance frameworks. Success depends on participation from fishing nations and enforcement mechanisms. Previous high-seas conservation efforts have struggled with compliance and funding gaps.

The West African coalition positions this move as both a conservation priority and a climate adaptation strategy. Healthy marine ecosystems generate resil
