"BASICC develops skills for the organization of vacant spaces in Europe, in connection with the European ecosystem of ""social and proximity economy"". Our consortium includes 17 members (France, Italy, Belgium, Latvia, Turkey and Germany): 10 economic actors, 3 vocational training providers, 3 higher education institutions (HE) and EVTA. In detail, 8 social economy organizations managing local places vacant in 5 countries are involved, with also 1 audiovisual company and 1 educational company. The vocational training providers are socio-professional integration actors present in France (AFPA), Italy (ENAIP NET) and Latvia (Vidzeme University of Applied Sciences). Higher education institutions develop training and research on the University as a common space in Rennes and France (EHESP and Gustave Eiffel University), and in Istanbul (Yeditepe University).Our program lasts 2 years. It starts with the creation of a European seminar at ENAIP NET headquarters, to build the ecosystem. We also develop pedagogical innovations: university degree sessions on vacant places and their reuse in shared spaces (green skills, level 5), a work-based learning for access to a professional title of digital mediation space managers (digital skills, level 5), a university course on acquired reflexive skills (resilience skills, level 7) and a digital and narrative platform. Our dissemination strategy is addressed to the managers of our organizations, through a protocol for designing national training courses on the management of common spaces. BASICC also allows learners to participate in a building occupation skills camp at a 25-year-old abandoned university. We communicate to our members and the general public through the production of a documentary on the skills developed by the learners. Our evaluation is oriented towards policy makers, to whom we can provide comprehensive analyses of the learning associated with occupying vacant spaces and the economic impact of the ecosystem created."
