A new study published in the prestigious peer-reviewed scientific journal Nature <\/em>today offers a combined solution to several of humanity\u2019s most pressing challenges. It is the most comprehensive assessment to date of where strict ocean protection can contribute to a more abundant supply of healthy seafood and provide a cheap, natural solution to address climate change\u2014in addition to protecting embattled species and habitats.<\/p>\n

 <\/p>\n

An international team of 26 authors – including researchers from Ifremer and the University of Montpellier and with the CNRS – identified specific areas that, if protected, would safeguard over 80% of the habitats for endangered marine species, and increase fishing catches by more than eight million metric tons.<\/strong> The study is also the first to quantify the potential release of carbon dioxide into the ocean from trawling, a widespread fishing practice\u2014and finds that trawling is pumping hundreds of millions of tons of carbon dioxide into the ocean every year, a volume of emissions similar to those of aviation. This work was partly funded by the Foundation for Research on Biodiversity (FRB<\/a><\/strong>), EDF and the Total Foundation, through the FREE<\/strong><\/a> and PELAGIC<\/a> <\/strong>research projects of the FRB’s Center for Biodiversity Synthesis and Analysis (CESAB<\/strong><\/a>).<\/p>\n

\u201cOcean life has been declining worldwide because of overfishing, habitat destruction and climate change. Yet only 7% of the ocean is currently under some kind of protection,\u201d said Dr. Enric Sala, explorer in residence at the National Geographic Society and lead author of the study, Protecting the global ocean for biodiversity, food and climate<\/em>.<\/p>\n

 <\/p>\n

\u201cIn this study, we\u2019ve pioneered a new way to identify the places that\u2014if strongly protected\u2014will boost food production and safeguard marine life, all while reducing carbon emissions,\u201d Dr. Sala said. \u201cIt\u2019s clear that humanity and the economy will benefit from a healthier ocean. And we can realize those benefits quickly if countries work together to protect at least 30% of the ocean by 2030.<\/strong>\u201d\u00a0<\/p>\n

 <\/p>\n

To identify the priority areas, the authors\u2014leading marine biologists, climate experts, and economists\u2014analyzed the world\u2019s unprotected ocean waters based on the degree to which they are threatened by human activities that can be reduced by marine protected areas (for example, overfishing and habitat destruction). They then developed an algorithm to identify those areas where protections would deliver the greatest benefits across the three complementary goals of biodiversity protection, seafood production and climate mitigation. They mapped these locations to create a practical \u201cblueprint\u201d that governments can use as they implement their commitments to protect nature.<\/p>\n

 <\/p>\n

The study does not provide a single map for ocean conservation, but it offers a first-in-kind framework for countries to decide which areas to protect depending on their national priorities. However, the analysis shows that 30% is the minimum amount of ocean that the world must protect in order to provide multiple benefits to humanity.<\/strong><\/p>\n

 <\/p>\n

\u201cThere is no single best solution to save marine life and obtain these other benefits. The solution depends on what society\u2014or a given country\u2014cares about, and our study provides a new way to integrate these preferences and find effective conservation strategies,\u201d said Dr. Juan S. Mayorga, a report co-author and a marine data scientist with the Environmental Market Solutions Lab at UC Santa Barbara and Pristine Seas at National Geographic Society.<\/p>\n

 <\/p>\n

The study comes ahead of the 15th Conference of the Parties to the United Nations Convention on Biological Diversity, which will gather end of 2021 in Kunming, China. The meeting will bring together representatives of 190 countries to finalize an agreement to end the world\u2019s biodiversity crisis. The goal of protecting 30% of the planet\u2019s land and ocean by 2030 (the \u201c30×30\u201d target) is expected to be a pillar of the treaty. The study follows commitments by the United States, the United Kingdom, Canada, the European Commission and others to achieve this target on national and global scales.<\/strong><\/p>\n

 <\/p>\n

\u201cSolutions with multiple benefits are attractive to people and leaders alike. Our pioneering approach allows them to pinpoint the places that, if protected, will contribute significantly to three big problems at once\u2014food security, climate change, and biodiversity loss.\u00a0 Our breakthrough in methodology can bring multiple benefits to nature and people,\u201d said Dr. Sala.<\/p>\n
