When did marine protection begin?

The tradition of managing fish stocks with temporary no-take zones isn’t new: temporary bans on fishing have traditionally been imposed by indigenous communities to maintain sustainable levels of harvest. Although such bans were driven by the need to protect food resources rather than protect marine biodiversity, the same method can be applied with great effect for ocean conservation.

Only in the late 19th century did the idea of protection enter government policy. Since 1872, when the first national park was created in the United States, recognition of the benefit of protecting areas has led to national governments assigning some degree of protection to around 130,000 areas around the world. Extending the concept of national parks from the terrestrial to the oceanic has however been a slow development and only recognized as a conservation tool in recent years.

The goal to protect at least 30% of the ocean by 2030 was adopted in 2022 in the Kunming-Montreal Global Biodiversity Framework, agreed at the 15th meeting of the Conference of Parties to the UN Convention on Biological Diversity. In an ideal world, at least 50% of the ocean would form one enormous and connected MPA. free from any form of exploitation. Just imagine how much good that would do the ocean!

High Seas MPAs

The protection of waters within the jurisdiction of coastal States is one thing. The idea of creating MPAs in areas lying beyond national jurisdiction was first highlighted at the Johannesburg Summit on Sustainable Development in 2002, when the need to maintain the productivity and biodiversity of important and vulnerable marine areas beyond national jurisdiction was recognised and a target date of 2012 set for the completion of an effectively managed, ecologically representative network of Marine and Coastal Protected Areas. Over twenty years later, the newly-drafted High Seas Treaty establishes a procedure for the establishment of Area Based Management Tools, including Marine Protected Areas, as one means of ensuring the conservation and sustainable use of marine biological diversity of areas beyond national jurisdiction, for the present and in the long term.

By establishing a “comprehensive system of area-based management tools, with ecologically representative and well-connected networks of marine protected areas” the treaty aims to “[p]rotect, preserve, restore and maintain biodiversity and ecosystems, including with a view to enhancing their productivity and health, and strengthen resilience to stressors, including those related to climate change, ocean acidification and marine pollution”. Proposals to establish ABMTs “formulated on the basis of the best available science and scientific information and, where available, relevant traditional knowledge of Indigenous Peoples and local communities, taking into account the precautionary approach and an ecosystem approach” are to be submitted to the secretariat. The Conference of Parties will decide on the establishment of ABMTs, reports on their establishment and development shall be submitted to the secretariat, and will be monitored and reviewed by the Scientific and Technical Body.
