Through this project we want to introduce into youth work field a new concept called Ecocentric Development, a revolutionary and interdisciplinary concept of Psychology inspired by Nature. It focuses on deeply connecting Youth with Earth, on creating and nurturing intimacy and belonging with Nature & empowering youth through developmental stages to develop their competences and take action. The Ecocentric Development invites youth to view again Earth as sacred, as a holy place of belonging and being in reciprocity with. The result is mature, empowered Youth who value Earth, deeply care for nature, act with responsibility and respect, take initiatives and lead the green transition with vision and with their uniqueness. The aim of the project is to support the professional development of youth workers and thus to contribute to the sustainable growth. Its objectives are: By the end of the project: 1. 90% of the youth workers involved will report an increase in competences (knowledge, skills, attitudes) related to Ecocentric Development, as measured by pre- and post-training questionnaires 2. 90% of the youth workers will report that they feel professionally competent to support youth to take an active role in the green transition, as measured by pre- and post-training questionnaires 3. 90% of the youth workers will incorporate at least 8 sustainability practices in their youth work practice, as evidenced by a follow-up survey conducted 3 months post training 4.
