Addap13 addresses to young people, boys and girls from 11 to 21 years old, from precarious social categories to favor their social and professional integration and reduce the risks of marginalization and exclusion. The sports practice, the construction sites of international solidarity are a part of tools which allow us to value and to encourage the public-spirited behavior by the meeting with " the other one ". From part their origins bound to the immigration, these young people are sensitive concerning problems of racism and discriminations. The domain of the sport and the competition do not make an exception sometimes by giving the "bad example" where we should wait for educational values of cohesion and sharing. 24 young people, boys and girls from 18 to 21 years old, were mobilized on the project have for common line to practise a sport and to arise from unprivileged backgrounds in their country of origin. Through this week we shall propose three types of teaching aids: - Workshops of exchange and debate about the questions of racism and discrimination, livened up by jurists and clubs of supporters which will allow to draw up a current situation in every country. This are times which will be dedicated to the expression of the young people through their testimonies, through their reflections as well as through their proposal to develop positively these situations. This work will give rise to the conception and the realization of a banner or a " tifo" carrier of a symbolic message who will be spread at the stadium Vélodrome of Marseille (or other) on the occasion of a match of big influx. - Friendly and cultural times dedicated to the knowledge of the heritage of Marseille and his region with a raising awareness of eco citizenship regarding environmental protection and regarding reprocessing of waste. - Times dedicated to the sports practice (hike, nautical activities, challenge multisports) through which will be proposed the activities favoring the cooperation rather than the competition. The communication concerning the outside part will lean on a documentary "clip" realized by the City of Marseille from the diverse strong moments of the project. Concerning the intern part, the young people will hold a "travel journal" telling the stay through verbal, photographic, video testimonies... This material will give rise to the creation of a "page facebook" to insure a distribution with a wider public.
