Drawing on a long history of cooperation between a french and a palestinian association, we would like to propose to a group of French and Palestinian youths an exchange in the two territories in order to solidify the dynamic of solidarity carried by the youth of Loire-Atlantique and West Bank. We decided to form a group of sixteen young people from 18 to 25 (eight Palestinian, eight French) having no previous international mobility experience. They will, in turn, welcome each other in Bethlehem and Nantes to discover the realities of the youth in each territory. Through the realization of collective activities, the discovery of the territory and formal and informal exchanges, the participants will experience a real intercultural encounter for twenty days. The production of various materials such as photos, texts and/or movies throughout the exchange, as well as the participation to public events related to international and intercultural awareness, will raise young audiences' awareness of international mobility and solidarity through. The group of youth will be involved at all stages of the project: from planning of each day to cooking, in order to enable them to gain self-confidence and autonomy in project implementation.
