This paper uses discourse theory to obtain a broader understanding of how research impact of sustainable tourism research develops in the environmental policy domain. Discourse theory shifts emphasis from the substance of science versus policy to the use of science in policy processes and explains the political dimensions of policymaking. We first review a well-documented science-policy gap in sustainable tourism research on climate change to develop an alternative conceptualisation of research impact. Then, using a case study approach, we investigate this framework by evaluating the impact of a PhD thesis about aviation's global CO 2 emissions on the Dutch aviation policy process. The case study shows research impact is entwined with various other elements, and embedded in a specific governance context. Research influenced contrasting science-policy interactions and contributed to conflicting policy actions and reactions. The impact of research in this case was manifested through the formation and interplay of multiple knowledge objects that were both embraced and marginalised. In settings like this, research is used to legitimise pre-existing policy positions rather than to develop new policies. We discuss the implications of narrow conceptions of research impact. The paper highlights the need for advanced policy analysis in sustainable tourism research.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
