OBJECTIVES The main objective of the project is to build the capacity of youth workers to promote mental wellbeing of marginalised young people through the valorisation of local natural resources and the evolution of youth work systems. This objective can be broken down into specific objectives: 1) Develop the competencies and methodological capacity of youth workers to use the environment to support mental health and wellbeing, 2) Reinforce European connections among youth workers in different areas (youth employability, environmental education, citizenship education, etc.) aimed at sharing good practices to support mental health and wellbeing 3) Build the capacity of organisations (both in the youth sector and beyond) to valorise local natural resources, understand the benefits and promote more nature-based activities for young people
