摘要:Expert organizations are often described as facilitators of the interactions between science andpolicy. In managing this boundary, they must also manage other boundaries, such as thosebetween different knowledge systems and between different categories of actors. However, howthis intersectional boundary work is performed, and what it implies, is still unexplored territory.Focusing on the Intergovernmental Science-Policy Platform for Biodiversity and EcosystemServices (IPBES), this study contributes knowledge on the intersectionality of boundary workand how it influences the production of global policy-relevant knowledge. This is done byexamining how IPBES socializes junior experts to become senior experts. This socializationprocess makes a number of norms and ideals visible and enables an analysis of how the knowhow of boundary work is passed forward from one generation of experts to the next. The studyanalyzes three boundaries: between senior and junior experts, between science and policy, andbetween scientific knowledge and indigenous and local knowledge. The findings show howintersectional boundary work is crucial in the creation of expert organizations and policy-relevantknowledge. In the case of IPBES, this study shows how the institutionalization of the organizationunintentionally has created restrictions for the boundary work between different knowledgesystems.
