The ‘Ocean Rise & Coastal Resilience Coalition’ led by the Ocean & Climate Platform, the Government of France, and the City of Nice will be launched a the UNOC3. It aims (1) to provide a platform for achieving better collaboration at every stage of the adaptation process for coastal cities and regions, by uniting coastal cities and regions representatives, international, regional and national networks of local authorities, financial intermediaries, scientific institutions and experts, civil society organizations, and land-use planners; (2) to advocate for the interests of coastal cities and regions, strengthening their representation and leadership in international political forums, conferences and summits.Among the three thematical priorities of the Coalition, one is to strengthen scientific cooperation and data access and sharing, to help cities and regions gain a better understanding of the challenges and scenarios for the future. In a context of great climate uncertainty, it is vital for coastal cities and regions to improve and extend local data collection, observation and climate projections, while drawing on multiple knowledge systems, including local and indigenous, to feed systemic models and inform decision.At the Ocean Ocean Science Congress, the Ocean & Climate Platform (OCP) would like to present the conclusion of the work realized under a working group, let by the IOC-UNESCO and the OCP, aiming to define how the Ocean Rise & Coastal Resilience Coalition can best support coastal cities and regions in the production and use of knowledge.The main deliverable will allow: Continuous assessment of scientific literature: Conduct rolling reviews to update coastal resilience needs from a multidisciplinary perspective, in collaboration with non-academic knowledge holders. Enhancing space infrastructure capabilities: Strengthen capabilities that support advanced services using space-based tools to address coastal resilience challenges. Leveraging AI, cloud systems, and advanced sensor technologies: Harness emerging technologies to allow communities to access expert support equitably, for example, assistance in drafting grant proposals. Encouraging civic engagement: Recognize the importance of citizen science and ocean literacy in fostering active civic participation in coastal resilience efforts. Building on existing initiatives: Coordinate local, national, and regional initiatives to overcome collaboration and data-sharing challenges. To achieve this, synthesize existing data-sharing tools
