This deliverable presents the data collection and integration framework supporting the nine CARDIMED demonstration sites. The deliverable defines key Nature-based Solutions (NbS) indicators, maps the data requirements needed to assess their impacts, and establishes tailored data integration strategies to support monitoring and WEFE Nexus modelling. By combining Earth observation, citizen science, in-situ measurements and regional datasets, it provides a practical roadmap for harmonised, FAIR-compliant data management and evidence-based evaluation of climate resilience actions across the Mediterranean.
