REHUBS addresses the issues of climate vulnerability in rural areas and small to medium-sized communities, which are particularly susceptible to climate risks such as droughts, heatwaves, wildfires, floods, and biodiversity loss. REHUBS’ goal is to enhance climate resiliency of these areas by developing an integrated framework of adaptation solutions, advanced digital tools, and participatory approaches, tailored to the specific needs of the rural communities. The project will design, implement and validate a Climate Risk Assessment model, an Advanced Early Warning System, Flood and Drought Modelling tools, Smart Irrigation Systems, a Circular Water Recovery Treatment, a Rapid Wildfire Detection System, as well as a Risk Assessment and Adaptation Platform that will recommend a list of cost-effective nature based solutions (NBS). REHUBS will promote knowledge transfer, enhance the adaptation capacity of local authorities, and upskill local actors through an online academy, an AI support chatbot and through fostering stakeholder collaboration through the project’s established Rural Micro Hubs (RMHs). The solutions developed in REHUBS will be implemented and validated across four Demonstration Cases, with replication in three additional Replication Cases, ensuring that they, not only address immediate climate risks, but also build long-term resilience by integrating climate adaptation strategies into local governance frameworks. Additionally, the project will introduce innovative financial instruments to support the sustainable implementation of these solutions, ensuring both their cost-effectiveness and replicability across different European regions. The project's outcomes will contribute significantly to enhancing the adaptive capacity of rural communities, supporting EU climate goals, and ensuring socio-economic and environmental sustainability in regions facing critical climate challenges.
