Social inclusion in Public Spaces and Active Citizenship through non formal Education (SPACE) was a project aimed at bringing together youth workers and representants of local bodies from Italy, Spain, Portugal, Greece, Norway, Sweden, Denmark and Romania in order to discuss about urban issues, mostly those affecting young people. Through this project we promoted the creation of a network of international associations to reflect about urban challenges and the related problems of social exclusion, and to explore new ways to encourage active citizenship among young people in their urban environments. The 16 participants, whose sending organisations had proved interest in the topics, gathered 6 days (from 12 to 18 January 2015) in Sassari, the capital of North Sardinia. The city of Sassari was the ideal setting to cope with the topics analysed during the project, since it has met a range of social problems linked to its unbalanced urban development in these last decades. The participants worked on four main thematic areas: risk of social marginalisation and exclusion in urban environments; opportunities for the cultural and economic revitalisation of the old town through art, sport, food and culture; sustainability and public transports; active citizenship and cooperation of young people with the decision makers in order to propose solutions to the urban challenges. The activities had been coordinated through non formal education methods (works in group, video productions, role play games, brainstorming). Some members of local cultural associations that works in the city center and some local administrators had been invited to discuss about local reality and problems. There had been also meetings with University students of the sociology course.Some activities took place outdoor, to promote Erasmus Plus and non-formal education and raise awareness on urban problems among the local community. During the last days of the project, participants had the chance to create working groups, to present ideas for future projects on urban issues, sustainability, promotion of young people participation in their local community. Through this project participants gained awareness on the value of active citizenship, they developed ideas on how to empower young people through initiative of social inclusion that might have an impact on their cultural, professional and personal development. In addition to that, the visibility of the event gave an example of how active citizenship and multicultural projects can help revitalize economic disadvantaged areas such as North Sardinia.
