To respond to the interest shown by individuals without local groups during the first edition, the 2025 Naturethon open call, titled “Citizens Growing Nature-Based Futures“, 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.

19 groups successfully completed the interactive process and submitted their projects for final evaluation, with 103 people actively participating. The proposals covered a wide variety of topics, ranging from flood risk to wildfires, biodiversity loss, and habitat degradation, and came from 14 countries across Africa (Ethiopia, Ghana, Malawi, Mauritania, Nigeria, and South Africa), Asia (Jordan, India, Pakistan, and the Philippines), and Europe (Italy, Georgia, Portugal, and Romania). The preliminary results were presented at the Italian National Conference on Science Communication in Trieste on 2 December 2025.

The Naturethon team reviewed all the ideas, providing operative feedback to shape feasible and meaningful actions. Representatives of the three proposals that stood out for innovation, feasibility, and social and environmental impact were hosted by the project at the Finance Innovation Festival in Brussels (February 3-5, 2026).
