BBNJ Treaty
"The first legally binding international agreement for conservation and sustainable use of marine biodiversity in areas beyond national jurisdiction (the high seas)"
The BBNJ Treaty (Biodiversity Beyond National Jurisdiction Treaty), formally known as the Agreement under UNCLOS on the Conservation and Sustainable Use of Marine Biological Diversity of Areas Beyond National Jurisdiction, is a historic multilateral agreement adopted in June 2023 after nearly two decades of negotiations. It provides the first comprehensive legal framework for governing the high seas — the two-thirds of the ocean that lies beyond any country's 200-nautical-mile Exclusive Economic Zone. The treaty rests on four pillars: (1) Marine Genetic Resources (MGRs) including benefit-sharing from genetic material found in deep-sea ecosystems; (2) Area-Based Management Tools including Marine Protected Areas (MPAs) on the high seas; (3) Environmental Impact Assessments (EIAs) for activities in international waters; and (4) Capacity Building and Transfer of Marine Technology to developing countries. The treaty operates under the umbrella of UNCLOS (1982) and requires 60 ratifications to enter into force.
Essential for UPSC GS-3 (Environment — marine biodiversity, international environmental law) and GS-2 (International Relations — multilateral agreements). The BBNJ Treaty fills a critical governance gap — until its adoption, the high seas had no binding conservation framework despite hosting unique deep-sea ecosystems. Questions may test the four pillars, the relationship with UNCLOS, the significance of MGR benefit-sharing (equity between developed and developing nations), and India's position on high seas governance.
