High seas

Accounting for almost two-thirds of the global ocean, the high seas and seabed areas beyond the limits of national jurisdiction (ABNJ) play a critical role in maintaining life on Earth. But, the current framework of governance related to conservation of marine biodiversity in ABNJ is weak and is characterized by large gaps. Gaps include the absence of rules to establish cross-sectorial marine protected area (MPAs) and other effective conservation tools.

About high seas governance

At the 2012 UN Conference on Sustainable Development (Rio +20), States committed themselves "to address, on an urgent basis [...] the issue of the conservation and sustainable use of marine biological diversity of areas beyond national jurisdiction, including by taking a decision on the development of an international instrument under the United Nations Convention on the Law of the Sea (UNCLOS)."

(UNCLOS) is an international treaty which was adopted and signed in 1982.Ìý

The Convention has created three new institutions on the international scene :

– theÌý,

– theÌý,

– theÌý.

Following a two year Preparatory Committee process, the United Nations General Assembly adoptedÌýÌý(24 December 2017) to convene an intergovernmental conference (IGC) to develop an international legally binding instrument on marine biodiversity in areas beyond national jurisdiction (BBNJ).

The process for the development of an international legally-binding instrument under the United Nations Convention on the Law of Sea on the conservation and sustainable use of marine biological diversity of Areas Beyond National Jurisdiction (BBNJ) has been running for over ten years.ÌýÌý

The negotiations are focused on four main components:ÌýÌý
