UNDERPIN is a project funded by HORIZON Europe Research and Innovation actions in support of the implementation of the Adaptation to Climate Change Mission (HORIZON-MISS-2022-CLIMA-01). UNDERPIN addresses critical gaps in monitoring, evaluation and learning (MEL) for climate adaptation across Europe. UNDERPIN is going to review existing climate adaptation and disaster risk reduction (DRR) indicators and integrate novel data sources, including Earth observation and citizen science. As well as, involving stakeholders in three pilot regions to cocreate and refine the framework, ensuring practical relevance and adaptability. A user-friendly dashboard with AI and machine learning tools will provide real-time analysis at the EU and regional level, helping decision-makers track progress, identify gaps, and make data-driven decisions. A citizen science and just climate resilience lens is used throughout the different activities of UNDERPIN. By aligning with EU and global reporting standards, such as the EU Adaptation Strategy and the UNFCCC, UNDERPIN is going to harmonize climate adaptation monitoring across governance levels, fostering a coordinated approach to resilience-building in Europe.
