From the beginning of the SCORE project to the end of the current reporting period, significant progress has been made in several areas. One of the main and first tasks was to develop a high-level baseline risk assessment of extreme climate impacts and sea-level rise across Coastal City Living Labs (CCLLs). Activities included comprehensive literature reviews, mapping past climate impacts, and integrating hazard exposure and vulnerability data into GIS-based maps, published in various deliverables and journal articles. Detailed flood risk assessments were also conducted for the WP3/WP6/WP8 frontrunner CCLLs, laying the groundwork for cost-benefit analyses of Ecosystem-based Adaptation measures and strategies for financial resilience. During the last 3 years, the CCLLs were established, implemented pilot operation plans, and engaged in co-creation, solution design, and pilot testing of interventions. Knowledge exchange and learning between CCLLs were facilitated, integrating lessons learned into ongoing processes for better outcomes. Sensor networks (WP4) were deployed, supported by citizen science and data collection, enhancing local resilience and adaptation efforts. The framework for the Digital Twin and Early Warning Support (DT-EWS) system (WP8) was designed and developed for some of the CCLLs, to enable simulations and real-time monitoring of the impact of extreme weather events. The design and development activities focused also on system efficient back-end and front-end integration, to provide users with a simple interface for scenario simulation and data visualization. The system’s deployment and validation are ongoing, with feedback from initial users informing further refinement. Dissemination efforts were extensive, involving the production of video content, webinars, social media engagement, and the development of additional resources like MOOCs, Infographics and GeoStories to maximize outreach and impact.
