This report summarizes the key challenges faced by the UACEG team during the implementation of activities in the URBiNAT co-creation process of the Healthy Corridor in Nadezhda district in Sofia. Important links between the healthy corridor plan and the changing planning system in-between two planning and programming periods have been discussed. Possibilities for integration and delimitation between the Plan and higher level planning instruments and between the territorial management instruments at local level are studied. A critical assessment of the possibility to coordinate phases and time frames, aims and thematic focuses, processes and results of URBiNAT project and the existing practices and administrative procedures of Sofia Municipality is made. Recommendations are suggested for improvement of interactions and communication between scientific research and introduction of innovations in spatial planning, as well as capacity building through action research and incremental incorporation of innovations.
