Le congrès One Ocean Science, un éclairage scientifique pour la 3e conférence des Nations unies sur l'Océan

Abstract

A defining feature of the 3rd United Nations Ocean Conference was its precursor: an international scientific congress designed to base political commitments on the best available knowledge. The analysis carried out in this article of the link between scientific recommendations and the commitments made highlights the value of such an approach, with the launch of several actions aimed at improving the protection and preservation of the ocean. This is the case, for example, with the establishment of a coalition of countries seeking to place the ocean at the heart of national climate plans, echoing the recommendation to use oceanbased approaches to achieve the objectives of the Paris Agreement. It is also the case with the significant increase in the surface area of marine protected areas, in response to the recommendation to protect marine ecosystems while honoring international commitments. The analysis also points to shortcomings, such as the failure of negotiations on the international plastics treaty. It further shows that certain issues raised by scientists, such as ocean-based food, have not been discussed during the conference. Overall, the efficacy of this science-policy interface argues strongly for its continuation at the 4th edition in 2028.La 3e conférence des Nations-Unies sur l’océan s’est distinguée des précédentes éditions par l’organisation en amont d’un congrès scientifique international. Celui-ci avait pour objectif de fournir des recommandations afin que les engagements pris par les Etats et gouvernements soient basés sur les meilleures connaissances scientifiques disponibles. Cet article analyse le lien entre les recommandations scientifiques et les engagements pris et montre l’intérêt d’une telle démarche avec le lancement de plusieurs actions visant à améliorer la protection et la préservation de l’océan. Elle pointe également des lacunes : certains sujets portés par les scientifiques n’ont pas trouvé écho dans l’agenda international dédié à l’océan. Le succès de la charnière colloque scientifique – conférence onusienne plaide pour sa reconduction lors de la 4e édition prévue en 202
