The present report analyses the current state of integration in Nature-Based Solutions (NBS) governance and planning processes within and across scales and dimensions of all CONEXUS cities: Barcelona, Buenos, Aires, Bogotá, Lisbon, Santiago, São Paulo, and Turin. Different levels of cooperation and conflicts may arise within and between governance structures, making integration a key issue in urban governance, in particular in the development of NBS. Integration is crucial for co-production and co-designing NBS, while the NBS establishment can also play a central role in encouraging integrating approaches.
