Municipalities are key agents in the transition to sustainability, and yet we have poorly developed theories and practices for how to facilitate the use of climate information by local governments in adapting to climate change. Existing research suggests that climate information is more likely to lead to adaptation actions when it is coproduced by researchers and policy makers because doing so increases the likelihood that the content of information is credible, salient, and legitimate. In this study, we explored how the coproduction process facilitated or hindered use of information from two climate adaptation projects in coastal New Hampshire. Based on 17 interviews and document review, we found that, contrary to expectations, highly engaged coproduction of knowledge may not be necessary due, in part, to preexisting trust among New Hampshire coastal municipalities, technical service providers, and researchers. However, we found in small towns with limited capacity, even the best climate knowledge is unlikely to be used without ongoing context-specific implementation assistance. Our research provides both practical recommendations for those actively advancing climate adaptation, as well as contributions to the undertheorized third phase of transdisciplinary research in which knowledge is translated to action.
