We address this deficit by reporting on the development and application of an interactive group-based methodology to enhance GI ‘thinking’ and interdisciplinary collaboration, drawing on the literature on the sociology of interactions. Our findings suggest that a game-based approach to GI problem-solving was successful in breaking down professional barriers by creating an informal learning arena, providing an enabling opportunity for participants to solve problems in an iterative, non-linear style to develop principles for action with transferability to ongoing plan formation. This style of problem-solving was characterised by shifting norms and routines of interaction, leading to problem re-framing and a search for alternative solutions.enThis is an Accepted Manuscript of an article published by Taylor & Francis in Journal of Environmental Planning and Management on 24 June 2015, available online: http://www.tandfonline.com/10.1080/09640568.2015.1042152Green infrastructureDeliberative methodsProblem-solvingJournal Article59584386510.1080/09640568.2015.10421522018-10-302012-W-MS-12 21https://creativecommons.org/licenses/by-nc-nd/3.0/ie/
