Assessing Nature? The Genesis of the Intergovernmental Platform on Biodiversity and Ecosystem Services (IPBES)

Based on an anlysis of the creation of an IPBES, our contribution addresses the progressive stabilization of an institutional design for assessing Nature. As regards the implementation of new forms of environmental governance, social science literature has zidely promoted norms of transparency, openness and participation. But so far, few researchers have focused on the way this disclosure model now concretely weighs down on real institutions and institutionalization processes. Little attention has been paid to the way this requirement can combine with other requirements or older models of action. In the case of IPBES, our goal is to question how the requirements of participation and transparency are put into practice. We will highlight the role of UNEP (United Nations Environment Program) in the institutionalization process of IPBES and see how the disclosure model is combined with other requirements which simultaneously involve the re-creation of "enclosure" (i.e. the need for academic sound science, or the usual way in which things are done at UNEP, i.e. bureaucratic practices). OUr work is based on an empirical study including documentation analysis and interviews
