Using systematic reviews to inform environmental policy-making

Abstract

There is a demand for scientific knowledge to make informed decisions in environmental policy. This study examines expectations of knowledge use, and how knowledge stemming from systematic reviews (SR) is being used through an analytical framework that distinguishes between instrumental, conceptual and legitimising evaluation use, as well as between process and product use. Empirically, we investigate knowledge generated from six SRs conducted through the Mistra Council for Evidence-based Environmental Management from the perspectives of those carrying out the SR and their targeted stakeholders. Our study reveals ways in which SRs are used and some characteristics that improve and some that hamper their usefulness. While the systematic method and the comprehensiveness of the SRs contribute positively to the usefulness, we found that the SRs produced were simultaneously too focused (lacking multiple perspectives), and too general (providing evidence on the effects of an intervention only at the general level) thereby restricting their usefulness. The time and resources it takes to produce an SR can also affect its usefulness compared to a traditional review.
