Enhancing Community Resilience Through the Uptake of Innovative Solutions: The C2IMPRESS Approach Galanopoulou M. I.; Bakogianni, E.; TZEMPELIKOS, D.; Ribas M. M.; Moragues, A.; Estrany, J.; Jiménez, J. D.; Tombul, E.; Cicekci, M.; Temiz, N.; Zózimo, A. C.; Craveiro, J.; Oliveira, M. M.; CRUZ, M.M.; Sfetsos, A. Dibyendu Sarkar This study bridges the existing gaps in quantifying risk and enhancing community defences by applying a cohesive five-pillar risk and resilience framework developed within the C2IMPRESS project. We assessed the anticipated impacts of various C2IMPRESS tools on community resilience across four European case study areas (CSAs): Egaleo (Greece), Mallorca (Spain), Ordu (Turkey), and the Centro Region (Portugal). Methodologically, a targeted survey asked CSA representatives to estimate the expected changes across 42 resilience indicators—encompassing social, institutional, economic, infrastructural, and environmental dimensions—following tool implementation. A public–private-civil partnership (PPCP) framework was also assessed across all sites to enable a comparative analysis. The results indicate that individual vulnerability and emergency preparedness are the most responsive dimensions, exhibiting significant projected improvements alongside institutional capacities and community trust. Conversely, the community economy emerged as the least flexible dimension, exhibiting minimal anticipated change. In conclusion, the C2IMPRESS framework effectively bridges disaster risk reduction and climate adaptation by integrating local knowledge into actionable interventions. However, while social and institutional resilience can be actively enhanced, improving economic resilience requires long-term structural adjustments beyond the scope of these localised tools.

Integration of clustering and principal component analyses in MCDA to identify feasible regions for managed aquifer recharge Panagiotou, C.F.; Martins, T.; Stefan, C. Dongmei Han Managed aquifer recharge (MAR) provides a nature-based solution to water scarcity issues, contributing to the design of effective water management policies. The novelty of this study lies in the integration of multivariate statistical methods within the framework of multicriteria decision analysis to provide nonsubjective, semi-automatic estimations of MAR feasibility based on three thematic layers, particularly intrinsic (hydro-geological, topographical, meteorological) features, water availability and demand for MAR. The concept of MAR typology is used to define the MAR problem and select a set of criteria for each thematic layer that are relevant for the Sado River Basin (southern Portugal). The hierarchical clustering algorithm (HCA) is used to partition the study area into distinct subregions based on selected criteria. For each subregion and thematic layer, a set of weight coefficients for the criteria is generated via products of the cumulative variance of the principal scores with the corresponding eigenvector matrix, which are then used to generate multiple realizations of the thematic maps. The results reveal that the majority of the study area (60%) has mean feasibility scores less than 0.54, whereas the remaining 40% (highest values) vary within a smaller interval (0.54–0.67). The present results are consistent with the previous study, with both identifying the same high-suitability regions. Additionally, it allows exploration of the variability in criteria weights across multiple realizations, providing a preliminary indication of how this variability can influence the results. This approach can easily be implemented in software and ultimately automated, supporting the unsupervised streamlining of the decision-making process.

The Importance of Assessing Air Quality in Nature -Based Solutions with a Focus on Health and Well-Being Barbosa, A. E.; Muehlan, H.; Schmidt, S. Ana Estela Barbosa; Margarida Rebelo Understanding the full potential of Nature-Based Solutions (NBS) is crucial in facing many societal and environmental challenges. The NATURELAB project promotes NBS for health and well-being and acknowledges the relevance of air quality within this context, which aligns with existing evidenceand EC directions. Air quality is key for enhancing urban population health and protecting vulnerable participants in Nature-Based Interventions (NBI), such as those with respiratory or cardiovascular conditions. NATURELAB selected, from the proposal stage, NO 2; PM10 and PM2.5 as the air quality parameters to be assessed at some of the experimental sites where NBI will take place. Compared to the Directive 2008/50/EC, the WHO’s air quality standards for the three selected air quality parameters are more aligned with the motivation and purposes of the project.
