    Beyond academia: a case for reviews of gray literature for science-policy processes and applied research
    (Elsevier, 2024) Yoshida, Yuki; O'Farrell, Patrick; Sitas, Nadia
    Gray literature is increasingly considered to complement evidence and knowledge from peer-reviewed literature for science-policy processes and applied research. On the one hand, science-policy assessments need to consider a diversity of worldviews, knowledge types and values from a variety of sectors and actor groups, and synthesize policy-relevant findings that are salient, legitimate and credible. On the other hand, practitioners and scholars conducting applied research are affected by the time lag and biases of academic publication processes. Gray literature holds diverse perspectives informative for science-policy processes as well as practical evidence unfiltered by commercial publication processes. However, its heterogeneity has made it challenging to access through conventional means for a literature review. This paper details one endeavor within the Values Assessment of the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES) to review gray literature using Google’s Programmable Search Engine. In the absence of a standardized approach, we build on the limited experiential knowledge base for reviewing gray literature and report on the potential applicability of our strategy for future reviews. Gray literature review results contrast findings of our parallel review of academic literature, underlining the importance of mobilizing different knowledge bases in science-policy assessments, evidence-based practices, and applied research.

    Inclusion of ecosystem services in the management of municipal natural open space systems
    (John Wiley and Sons Inc, 2024) Wessels, Nadia; O'Farrell, Patrick; Sitas, Nadia
    Unprecedented urbanisation in the global south is transforming natural urban landscapes, impacting on the ability of nature to provide essential ecosystem services. Within the context of pressures facing many urban natural open spaces, particularly in Africa, we used a local municipality in South Africa as a case study to (i) identify local government priorities for a natural open space system; (ii) develop an understanding of whether, and how, ecosystem services are considered by local government, and the reasons thereof; and (iii) ascertain the extent of proactive planning regarding regulating and other ecosystem services, including the temporal and spatial scales, and implications. In-depth qualitative interviews (n = 12) were undertaken with senior municipal officials representing departments whose work impacts the environment. Municipal decision-support documents were also analysed for any direct and/or indirect references to ecosystem services. Planning for, and management of, ecosystem services provided by natural open spaces is influenced by interwoven infrastructure, municipal service delivery and equity challenges, complex institutional constraints and poverty, with little focus on the socio-economic opportunities and other benefits of natural open space systems. Values, perceptions and knowledge also influence the management of ecosystem services.
