This Atlas contains detailed descriptions of 13 European examples of soft territorial cooperation areas. The selection of cases presented makes no claim to comprehensiveness nor (statistical) representativeness. Cases were selected out of a multitude of identified examples with a view on fitting the project's definition of soft territorial cooperation. Soft territorial cooperation areas were defined as initiatives that define the sectoral scope and geographical boundaries in an ‘open' or ‘fuzzy' way, based on a notion of ‘community of intent' as a voluntary collaboration open to public and private actors who decide to jointly address territory-specific opportunities and challenges. Their other main characteristics are: • a medium to long term integrative perspective (i.e. not limited to the implementation of a single project); • seeking to enhance the capacities of involved players, making them actors of their own development; • renewing relations between institutional levels, sectors of activity and types of actors (e.g. NGOs, private companies, local and regional authorities, agencies…). The soft territorial cooperation areas presented in this Atlas show variations of these characteristics and “openness” in how they define their cooperation area, partnership, thematic scope, type of interventions and governance structure. The way in which case study descriptions are structured shall allow the reader to quickly capture case study characteristics, make cross-connections between the different cases and draw his/ her own conclusions from the presented material. The project team's findings and conclusions can be found in the main project report.
