Towards Integrated Management of Regional Marine Protected Area Networks

Marine protected areas (MPA s) are an important tool for protecting marine ecosystems both within and beyond national jurisdiction, but the integrated management of MPA s is challenging due to the institutional fragmentation that exists in international ocean governance at global and regional levels. In the absence of fundamental reform of international ocean governance, integrated management of MPA s can at present only be achieved through cross-sectoral cooperation and coordination between relevant international institutions. Understanding regime interaction in this context requires an analysis of both the relevant legal framework and the manner in which coordination mechanisms operate in practice. This article carries out a case study of regime interaction between the Antarctic Treaty and the Convention on the Conservation of Antarctic Marine Living Resources, as well as other relevant institutions, in order to identify the key opportunities and challenges for promoting the integrated management of regional MPA networks in practice. It will also consider how the cooperative arrangements for the regional management of the Southern Ocean may provide lessons for the development of a new legally binding instrument for the conservation and management of biodiversity in areas beyond national jurisdiction.
