In this paper I interrogate the relationship between environmental science and local governance in the United Kingdom. Effectively linking science and policy is critical to sustainable planning, and within the rhetoric of evidence-based policy it is often assumed that science conducted in a locality will feed linearly into the governance of that locality. This assumption is unpacked through the detailed study of an end-user-oriented environmental research project. I argue that the reproduction of separate scientific and political spheres prevented the research from being relevant to the governance of that locality. Theoretical and practical approaches to the spatialities of the research–policy interface are considered in order to politically reconstruct the local as a meaningful field of environmental governance.
