ABSTRACT
This chapter presents a case study of Spanish Project Pla Buits Urbans amb Implicacio Territorial i Social (BUITS). Pla BUITS aimed at re-using empty spaces throughout the city, in order to improve citizens' quality of life. Pla BUITS invited neighborhood entities to co-manage abandoned parcels, and as such is a way to make citizens co-responsible for the public environment they are living in. The local organizations and individual citizens (the co-producers in this case) are totally responsible for the empty spaces they are managing and, therefore, are in charge of implementing the proposed project, be it an urban garden or a bikes garage. Non-promoting organizations are mainly supporters of the initiative and play specific roles at different times. Regardless of the specific role as (non-)promoting organizations, all co-producers developed important feelings of ownership. They expressed a willingness to take responsibility for the empty space.
