Distribution and selection of experts in the intergovernmental science-policy platform on biodiversity and ecosystem services (IPBES): the case of the regional assessment for Africa

In 2013, the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES) agreed to carry out a regional assessment for Africa. Since then, roughly 100 authors have been working to deliver, in 2018, a document that not only synthesises existing knowledge on biodiversity and ecosystem services for the African region but to distil from it knowledge that is relevant, credible, and legitimate for both societal and scientific practise. This requires, firstly, to carefully constituting the group of authors and, secondly, to design an assessment process that allows for deriving at an integrated perspective amongst these experts. Such a joint process of knowledge production that encompasses both interdisciplinary and transdisciplinary collaboration can be framed as co-creation. In this contribution, we analyse whether the IPBES African assessment accounts for these two prerequisites for an effective assessment process. Our particular interest lays in the question whether scholars from social sciences and the humanities are sufficiently involved. Our analysis is based on the curriculum vitae of 97 members of the expert group, and reads quite straightforward: there is an overall lack of non-natural science perspectives and expertise that might lead to essential knowledge and data gaps when wishing to understand the effects of the diverse human concepts of and activities on biodiversity and ecosystem services. In order to address these gaps and to derive at an assessment report truly relevant for policy makers as well as other social and scientific actors, IPBES needs to widen its outreach to networks of scholars from the social sciences and the humanities and to inform them appropriately about the specific roles they could play within IPBES processes, particularly assessments.
