A leading force for ocean diplomacy and science
Belgium’s leadership in ocean diplomacy reflects a deep commitment to international cooperation and marine protection. As the founding nation of the Blue Leaders alliance, we have united over 30 countries to advocate for protecting 30% of the ocean by 2030 and advancing the ambitious BBNJ agreement. Even during the COVID-19 pandemic, Belgium, alongside Monaco and Costa Rica, sustained global momentum through the High Seas Online Dialogues, ensuring continued progress in ocean governance.
Brussels remains a key diplomatic hub where nations collaborate on shared marine challenges, reinforcing our role in shaping international marine policy.
This diplomatic leadership is underpinned by Belgium’s excellence in marine science, which provides the data and innovation necessary for effective ocean management. Hosting critical global infrastructure such as the World Register of Marine Species and the Ocean Biodiversity Information System, Belgium supports the foundation of global marine biodiversity research.
With 144 marine research groups spanning 20 disciplines, our scientists publish between 700 and 900 peer-reviewed studies annually—over three-quarters in international collaboration. Investments like the Research Vessel Belgica and advancements in Marine Spatial Planning further cement our position as a global leader in sustainable ocean management. Through initiatives such as the Ocean Teacher Global Academy and the Capacity Development Hub in Ostend, we actively share knowledge, fostering a collaborative and globally inclusive approach to marine science.
