Who and what exactly qualifies as a planner was difficult, the discipline reinvents itself constantly. This difference was also observed in their definitions of climate change adaptation. There was a clear divide between a group that believed in incremental change and a group that believed that climate change adaptation requires transformative change. The role of planners in climate change adaptation was more clear, which is to break through sectoral walls and bring together stakeholders. This enables institutions to overcome barriers and realize opportunities. Interestingly, this role overlaps with the category in which most barriers and opportunities were observed, which is the social interactions attributes of institutions. Particularly social connectivity among and within the institutions was the most important cause of barriers and opportunities. %L theses_frw1515 %A P.
