NATURETHON | Innovative Tools for Success Stories

The second 2025 Naturethon webinar, co-hosted by the NATURANCE and ARCADIA projects, took place on 28 October 2025. Nature-based Solutions expert Marcelo Gerlach from ICLEI Europe introduced the Youth Inclusion Toolkit for Local Authorities, developed through a co-creative process within the NBS EduWorld project. The toolkit offers 12 flexible tools to engage young people in local decision-making — from hackathons and role-playing games to youth councils, participatory mapping, innovative citizen science methods, and activities in “third spaces” such as parks and libraries.

Following this, Nicolas Keller, Sustainability Educator at Växtverket, and Ludwig Wahlund Sonesson, Project Manager at the City of Malmö, illustrated how the City of Malmö, Sweden—one of the ARCADIA project‘s Co-Innovation Labs—orchestrated a network of local associations to engage diverse citizen groups in the development of urban Nature-Based Solutions, with a focus on community and sustainability.

The event concluded with a lively Q&A session and an interactive workshop for groups participating in, or interested in, the Naturethon journey. Participants began co-developing NbS ideas tailored to their own local contexts, setting the stage for future collaboration and innovation.
