The “Transforming Systems and Leading Bioregional Regeneration” (TRANSFORM) Erasmus+ mobility project for youth workers was designed in full alignment with the objectives of the Erasmus+ Programme, and specifically Key Action 1 in the youth field. Through this project, we aimed to empower participants by strengthening their personal, professional, social, and linguistic competences, increasing their motivation and sense of purpose in their current and future roles. We also sought to improve the quality of services offered by participants and their organisations, particularly for youth and leaders of socio-ecological initiatives, by promoting active, participatory methods and reinforcing civic and environmental awareness. Furthermore, the project aimed to provide experiential learning in essential skills for collaborative regenerative work, including complex systems thinking, mapping, and bioregional regeneration, thereby contributing to the development of meaningful employment opportunities in the regenerative sector and supporting full and fulfilling labour market inclusion. Another key objective was to foster active citizenship and strengthen sustainable, inclusive cooperation among European actors. To achieve these goals, the project brought together six partner organisations and 30 youth workers from Greece, Spain, Italy, Belgium, France, and Portugal for a 14-day experiential training activity (excluding travel days), hosted at The Southern Lights agroforestry research, learning, and demonstration site. The mobility created a space for deep exchange, collaboration, and non-formal learning in a living laboratory setting rooted in regenerative practice. The training was conceived as an integrated theoretical and practical learning journey focused on systems science, systems change, and bioregional weaving. It prepared participants, their organisations, and the youth and youth workers they engage with to lead multi-stakeholder collaborations capable of regenerating their territories. At its core, the project sought to engage, connect, and empower youth workers, and through them the young people they support, in line with the EU Youth Strategy 2019–2027. Building on our previous projects, especially “TIME TO ACT–TOGETHER,” this training represented a continuation and deepening of our work on ecosystem services and regenerative practices. We responded to a shared need among our organisations to equip youth workers and the upcoming generation of professionals with the tools, mindsets, and collaborative capacities required to address global climate change and its local manifestations. The project strengthened our collective ability to understand, map, and intervene in complex systems, while contributing to the broader mobilisation of regenerative cultures and systems across Europe. Inspired by the positive impact of initiatives such as the Bioregional Weaving Lab in Europe, whose representatives contributed as trainers, we aimed to strengthen both our internal organisational capacities and the capacities of youth workers to cultivate resilience within their bioregions. The intention was to support the creation of locally embedded yet far-reaching impact networks capable of driving regenerative transitions across multiple sectors. Guided by three experienced trainers representing leading global changemaker organisations, participants were supported in translating learning into practical application. Particular emphasis was placed on ensuring that participants could effectively transfer the knowledge and multidisciplinary skills gained to the communities they serve, especially young people facing geographical, economic, or educational obstacles, including NEETs. The training focused on four main areas of competence development: complex systems science and thinking; the inner work of changemaking; systems change; and bioregional weaving and regeneration. Through this holistic approach, we aimed to cultivate youth workers who are capable not only of understanding complexity, but of leading collaborative, inclusive, and regenerative transformation processes within their territories and networks.
