By implementing Nature as a Mentor: Shinrin-yoku in Youth Work Practices, we aim to strengthen the ability of youth workers across Europe to support young people’s mental health, resilience, and ecological awareness through innovative, evidence-based non-formal education. Our objectives are: Build professional competences of youth workers in nature-based and inclusive methods Equip 24 youth workers with the skills to design, facilitate, and adapt shinrin-yoku sessions. Link directly to the ETS Competence Model for Youth Workers (facilitation, designing learning, inclusion). Target: ≥80% of participants report confidence to use shinrin-yoku with youth after training. Integrate mental health and well-being as core elements of daily youth work Enable youth workers to embed short well-being practices (10–20 min) into weekly youth centre activities and longer sessions in camps or school cooperation. Target: ≥8 pilot activities within 3 months, reaching 160 young people; ≥400 reached within 12 months. Youth Goal 5: Mental Health and Well-being. Enhance inclusion and accessibility in youth work practices Develop adaptations of shinrin-yoku for young people facing economic, cultural, social, and geographical barriers (NEET, migrant, rural youth, early school leavers). Target: ≥40% of pilot activity participants from fewer opportunity backgrounds. Erasmus+ priority: Inclusion & Diversity. Strengthen organisational capacity and innovation in youth work Ensure each of the 8 partner organisations integrates shinrin-yoku into at least one regular programme. Train at least 120 additional youth workers internally through peer-to-peer transfer. Erasmus+ priority: Quality, innovation, and recognition of youth work. Foster green practices and digital transformation in youth work Promote forests as learning environments to connect well-being with sustainability (Youth Goal 10: Sustainable Green Europe). Co-create and disseminate a multilingual digital “Forest Toolkit” (5 languages, 200+ downloads within 1 year). Erasmus+ priorities: Green transition & Digital transformation. Promote civic participation and European cooperation Empower youth workers to engage young people in local consultations and outdoor civic events linked to green spaces and well-being. Target: at least 8 municipalities and 12 NGOs engaged within project lifetime. Erasmus+ priority: Participation in democratic life.
