She will contribute to the activities of the association by facilitating writing workshops, street libraries, creating educational material for school teachers to raise awareness on the Gypsy culture.This project will be led following a methodology acquired by experience, as Pistes Solidaires has been working on learning mobility for years. This methodology is based on: a good knowledge of administrative tools of the Erasmus + program, a good communication and “transparency policy” with our partners, an in-depth tutoring with the volunteers.A mobility experience for young people not in education, employment or training will lead to their empowerment and the development of transversal skills. This personal and professional development will allow a better integration once back in their own countries, but will also have a considerable impact during the volunteer period. Indeed, they will raise the awareness of local youngsters about the issue of environment and of social challenges of youth. They will enable youngsters to live an intercultural experience and learn about opportunities for international mobility. In a nutshell, the European volunteers will become “multipliers” in order to share the values that they believe in and knowledge that they carry.To sum up, this project wishes to answer to society and environmental issues on the scale of the PACA region, but also in Europe and the whole world. Hosting European volunteers in organizations partners of this project represents a solution to some needs in local and socio-cultural development. Thus, while being involved in active organizations, the young volunteers will get to know to keys for a sustainable and responsible behavior towards the planet, and towards others. Then, they will the able to promote this behavior towards their peers, in order to create a civil and responsible Europe.
