Climate change adaptation is challenging in community planning because of the conflict between planners’ scientific knowledge and residents’ local knowledge. Focusing on the Bansong Pilbongoreum community in South Korea, we suggest a community-based adaption plan that uses local knowledge and builds consensus between local residents and planners by identifying problems and planning objectives. We applied this plan to our case study, using in-depth interviews, a community workshop, local knowledge, and scientific climate adaptation measures to identify the community’s problems and develop a plan. Planners and residents must communicate so that planners can incorporate local knowledge into effective planning objectives for community adaptation.
