Historic High Seas Treaty enters into force with Türkiye as a party

The United Nations' High Seas Treaty, a groundbreaking global agreement aimed at protecting marine biodiversity in international waters, formally entered into force on Saturday, January 17. The treaty, officially known as the Biodiversity Beyond National Jurisdiction (BBNJ) agreement, achieved the required 60 ratifications to become international law, marking a new chapter for ocean governance.

A New Era for Ocean Protection

The treaty establishes the first comprehensive legal framework for creating protected areas in the high seas, which constitute about two-thirds of the world's oceans and were previously subject to fragmented and weak governance. It mandates environmental impact assessments for activities that could harm these vast, shared marine ecosystems. Turkish marine scientist Bayram Ozturk described the agreement as inaugurating a "new era for global ocean protection," clarifying that it creates a legal basis for regulating activities like fishing rather than imposing a blanket ban across all international waters.

Türkiye's Strategic Engagement

Türkiye's participation as a party to the treaty is seen as strategically significant. Experts note that this engagement bolsters the nation's environmental diplomacy profile on the world stage. Levent Bilgili, a maritime studies academic, highlighted that the treaty will require vessels from participating states to adhere to higher standards of environmental responsibility. Türkiye's active role strengthens its position as the host of the upcoming UN Climate Change Conference (COP31), scheduled for November in Antalya and Istanbul, where ocean-climate linkages are expected to be a key agenda item.

Addressing a Critical Governance Gap

The treaty's implementation seeks to close a major gap in global environmental law. Until now, conservation measures were largely confined to waters under national jurisdiction, leaving the majority of the ocean vulnerable. The agreement provides a mechanism for international cooperation to safeguard marine life, ensure sustainable use of marine resources, and enhance scientific collaboration. This multilateral effort reflects a growing consensus on the need for collective action to preserve vital global commons for future generations.
