Geodesign to advance boundary work in urban planning: A study in Stockholm focused on nature-based solutions

Geodesign supports collaborative urban planning by managing ‘boundaries’ between diverse knowledge holders. However, there is a paucity of empirical evidence of its contribution to ‘boundary work’. This paper aims to evaluate how a geodesign process facilitates knowledge co-production through boundary work and to assess the scientific credibility, political saliency, and procedural legitimacy of its outputs in urban planning. We propose a replicable geodesign framework to assess boundary work, and test it in a case study on urban transformations with nature-based solutions in the Skarpnäck district of Stockholm, Sweden. Findings indicate that all geodesign steps facilitated communication by promoting collective reasoning. Participants acknowledged contributions to knowledge co-production and decision-making by mediating between different perspectives. However, data quality and modeling simplicity were identified as critical factors affecting the outputs’ perceived credibility. Future applications should include co-designing the geodesign process, improving capacity and skills, and facilitating more integrated planning.
