This is the report of the "Public Infrastructure and Social Services" Community of Practice (CoP) within the project "ROBUST - Unlocking Rural-Urban Synergies". A total of seven Living Labs (LL) participated in the CoP and shared their experiences and expectations, exchanged views on a variety of topics and governance systems and developed common knowledge. The report was informed by the seven LL reports and the results of the numerous joint working sessions in the context of the ROBUST Consortium Meetings. Furthermore, the findings from the good practice examples and short reports (see appendices), which were developed in the CoP, were used to inform this report.
