Abstract
This study examines young people's involvement in regional sustainability transformation processes based on a real-world experiment in a community of 5700 inhabitants on the southern outskirts of city of Vienna, Austria. The eight-month experiment aimed to explore methods and tools for transdisciplinary co-creation with youth, the impact of structural conditions on their participation and the effects of their integration. Findings highlight the crucial roles of topics relevant to youth, a trusted intermediary like a youth worker, and structural conditions such as political support and resource allocation in enhancing youth engagement success. Collaborative decision making with policymakers and direct communication were also key to effective participation. The real-world experiment laid the groundwork for future participatory methods and had an impact on youth-community relations. It affirmed the role of youth in regional development, with effects that extended beyond the immediate scope of the experiment in terms of time, space, and topic.
