We designed the SustArt - Sustainable Art for Mental Health project as a youth exchange that addresses two pressing challenges in the lives of young people today: the growing need for mental health support and the urgent call for sustainability. From the perspective of youth work practice, the project aims to provide young people with meaningful, creative, and empowering experiences that strengthen their resilience, foster intercultural dialogue, and encourage environmental responsibility. Youth work practice emphasises creating safe, inclusive, and engaging spaces where young people can explore their identities, build skills, and grow through non-formal learning. This project applies these principles by using art and nature as vehicles for personal development and collective learning. Through carefully designed workshops, intercultural dialogue, and collaborative art-making, youth will have the chance to express themselves, reflect on their lives, and connect their personal well-being with wider ecological challenges. The main objectives of the project are as follows: - To introduce young people to diverse art forms that support mental health and self-expression, using creative practices as tools for stress relief, resilience-building, and enhanced self-awareness. - To raise awareness about the interconnection between environmental and personal well-being, highlighting how sustainable living and connection to nature can positively influence mental health. - To foster intercultural dialogue and teamwork through joint creative projects, ensuring that participants experience the value of collaboration across cultural boundaries while appreciating diversity. - To equip participants with practical skills for creating sustainable art using natural or recycled materials, encouraging environmentally responsible artistic practices that can be transferred to their local communities. - To exhibit and celebrate youth-created artworks as a collective achievement, showcasing both the individual and group efforts of participants, while raising visibility of Erasmus+ opportunities in the wider public. From a youth work perspective, these objectives reflect the values of empowerment, participation, and inclusivity. The project creates a learning environment where young people are encouraged to step outside of their comfort zones, challenge stereotypes, and build confidence in their ability to shape both their own lives and the world around them. It also ensures that young people with fewer opportunities are included, giving them equal access to international mobility and intercultural learning. Ultimately, the project aims to leave lasting impacts at both the individual and community level. Participants will gain skills and attitudes that are valuable for their personal growth and employability, while the artistic outcomes and dissemination activities will inspire their peers and communities to adopt sustainable practices and recognize art as a tool for well-being and dialogue. In this way, the project strengthens youth work practice by combining creativity, sustainability, and mental health support in an innovative and inclusive way.
