Researchers from IRD, the CNRS and Memorial University of Newfoundland (Canada) have assessed the capacity of the principal ocean management tools to achieve the "Conserve and sustainably use the oceans' sustainable development goal (SDG). They have shown that certain multi-sectoral mechanisms, such as marine protected areas, are the most effective in reconciling the ecological, economic and social dimensions of this SDG. These results were published in the journal Nature Sustainability on 14 December 2020, and will make it possible to improve operational guidelines for the preservation of the oceans.
