How do information flows affect impact from environmental research?-An analysis of a science-policy network

Evidence of the impact arising from environmental research is increasingly demanded. Exchanges between science providers and actors that use scientific knowledge to address environmental problems are recognized as a key component of the mechanisms through which impact occurs. Yet, the role of interactions between science and policy actors in delivering and shaping research impact is not well established. We aim to better understand how transfer of science in a science-policy network generates impact. Our approach relies on an exploratory social network analysis (SNA), applied to a network of organisations working on land and water management in a catchment in the UK. We analyse flows of scientific information across these organisations and how those contribute to impact, which we conceptualized as change in organisations at three levels: increased awareness, operational change and strategic change. We find that organisations occupying central positions in the network facilitate the transfer of science and influence the level of change achieved. We also find that the effectiveness of the flows of information and impact delivery depends on boundary organisations, in particular public regulatory bodies, that connect agents with others. Moreover, intended change reported by science providers does not often transform directly into change as reported by the receivers of the information. We conclude that both exchanges between researchers and research users and the role of boundary organisations are key to impact delivery and making change possible. This is valuable for understanding where improvements to information flows between organisations might enhance impact.
