ACCOORD is a social and cultural association based in Nantes in the Pays de la Loire region. It is a non-profit organisation under the law of 1901 that manages 22 socio-cultural centres, neighbourhood centres and an open-air space. Under a public service delegation agreement, ACCOORD also manages 40 children's leisure centres, 17 teenage activity areas (11/15 year olds) and organises trips and mobility programmes in France and abroad. Its facilities offer residents a wide range of educational leisure activities for all ages. Every year, 12,000 Nantes families benefit from these activities. European and international issues are at the heart of our associative project. We know from experience that mobility and intercultural exchanges are factors in the development of young people. Mobility enables them to: - discovering other people and the world, and sometimes one's own history - The development of skills, curiosity and the ability to ask questions - The exercise of citizenship through a different relationship with the world and with time - Building a sense of belonging to the European community In addition, many young people from the Nantes area and members of our association have never had the opportunity to travel. Our members of the public and our staff have many needs that can be met by mobility (taking a step back from their daily lives, independence, self-confidence, cultural discovery, etc.). These observations have led us to carry out Erasmus+ mobility projects in the youth sector. Our objectives for this first project were as follows: 1) Contribute to the development of European citizenship and create a political and ecological awareness 2) To develop and enhance the cross-disciplinary skills of young people and staff 3) To act as an intermediary, enabling young people from different countries to meet each other, to act as a driving force in the Nantes metropolitan area
