Centering equity, diversity and inclusion in environmental evidence synthesis: from awareness to action

Abstract Knowledge generated through evidence synthesis is an approach that decision-makers can take to inform policy and management decisions. Evidence syntheses, such as systematic reviews, provide quantitative and qualitative summaries of this evidence, using structured methods that make them comprehensive and repeatable. While such summaries can improve the applicability of scientific evidence and make it more accessible and useable for decision-makers, who engages in synthesizing evidence can be an important determinant of the results (e.g., legitimacy, validity and representativeness). Currently syntheses often focus on available, published literature, which can fail to represent the diversity of languages, experiences, and communities involved in producing high-quality evidence. Drawing on our diverse experiences in evidence synthesis we identified ways that principles of equity, diversity and inclusion (EDI) can be incorporated into the evidence synthesis process and outputs. We identify three core phases (pre-production, production, and post-production) that align with current synthesis processes, and where EDI concepts could be incorporated. We reflect on current synthesis structures and processes and highlight opportunities to incorporate new practices that will better reflect the true evidence base and minimize biases. We provide resources and examples of good practice to help guide authors. A growing awareness of the importance of EDI makes this an opportune time to rethink how review teams engage in evidence synthesis to ensure that the processes of evidence synthesis and their outputs are underpinned by practices of equity, diversity, and inclusion.
