YCC will alternate meanwhile of studios(workshops), reflection, meeting between associative actors and researchers leading researchs on this subject. We wish to raise)the questions and to allow the young people to put a look critical and built on the climate food problems both the scale local and European. It will also be a question of working on the European citizenship and of showing that the cultural differences are a benefice to build a better world, fighting against the disparities and the discriminations. The young people will be for 7 days in a life in collective so allowing them to work on a mutual knowledge of their cultures. This project involves the young people in all the stages of the project, creating a real space not only of exchanges but also of construction. A accompaniment will be brought by our structure to develop the acquisition of skills so much in the knowledge to be, know how to make and know how to act.
