The project Aeiphoria, was conceptualised after several projects we worked in Hopeland as well as our own observations as trainers and participants that sustainability for youth workers is a great idea but it is difficult to put it in practice. There are several projects about the theme, but we observed that what is need not only for youth workers but also to trainers or everyone that they lack the ability to put theory into practice. They don’t know how to increase the sustainability features in their projects or they know the idea of sustainability but they lack of skills to create a project out of it for youth. Take this into consideration along with the multiple challenges we face as universe with air pollution, climate change, deforestation and other, it is high time that we try to collaborate and create projects that can help everyone to be more sustainable. Our main aim is to give youth workers the skills and information and support them to raise awareness about sustainability, to help others to become more sustainable, to give them the space to make their projects more sustainable and create initiatives in and outside the programme to promote sustainability. Objectives The objectives of this project are: 32 youth workers to understand the multiple aspects of sustainability to support youth workers to make their projects more sustainable (including social,economic, environmental aspects) to understand that sustainability challenges such as climate change are global, interdisciplinary and systemic and need collaboration worldwide to be tackled to create 6 video tutorials about how to promote sustainable lifestyle to people and how to build mini initiatives about sustainability help youth workers to create sustainable projects (an initiative that will tackle an issue like rubbish, air pollution, climate change) big or small in order to help others to become more sustainable, make changes in their life and create sustainable projects on their own to live in a simulative sustainable community for 9 days to design follow up 9 (one of each partner) activities in their local community or follow the project they designed during the TC to disseminate the knowledge acting as multipliers and share the skills acquired during the TC by youth workers promoting the video tutorials and continuing their designed project to strengthen cooperation between partner organisations and to provide them with the idea to develop new projects for sustainability or with sustainability principles.
