Abstract

This study examines support for climate adaptation planning and the role of perceived risk, uncertainty, and trust on adaptation of U.S. coastal communities. This assessment is based on the analysis of web-based questionnaires ( n = 137) among state, local, and non-government organization (NGO) planners in Alaska, Florida, and Maryland. Ordinal regression and correlation analysis were used to assess which factors are related to support for adaptation during two planning stages. Findings from this study suggest the influence of perceived risk, uncertainty, and trust on support for climate change adaptation (CCA) varies across two stages of adaptation planning (support for the development of plans and willingness to allocate human and financial resources to implement plans). The disaggregation of planning entities into different study areas and levels of management revealed significant differences in the relationship between perceived risk, uncertainty, and trust and support for CCA planning. These findings have implications for the design of communication and engagement strategies.
