The report presents the outcomes of the second online citizen engagement forum, held by the NATURANCE consortium as part of the project’s Plan for the Exploitation and Dissemination of Results, under the initiative called Naturethon. The initiative aimed to organize citizen group meetings throughout Europe and beyond, focused on identifying innovative fi nancial strategies for Nature-based Solutions (NbS) in the context of climate action and disaster risk mitigation. Naturethon targets a diverse range of participants, including students from various backgrounds, young professionals, local administrators, and representatives of environmental NGOs. The second edition, titled “Citizens Growing Nature-Based Futures”, ran from 5 September to 8 December 2025. To respond to the interest shown by individuals without local groups during the fi rst edition, the 2025 open call allowed individual registration through a statement of interest to form new groups. Online collaborative boards were introduced to guide participants more effectively as they developed their projects during each hands-on webinar. Once completed, the boards were compiled into a logbook, which served as the foundation for the final submission. In terms of outcomes, 19 groups successfully completed the interactive process and submitted their projects for final evaluation. Altogether, 103 people actively participated in this edition by submitting a fi nal project. The proposals covered a wide variety of topics, ranging from fl ood risk to wildfi res, biodiversity loss, and habitat degradation, and came from 14 countries.
