This conference, that will take place on 11-12 December 2009, is organized by the BioTEK project with the support of the Muséum National d’Histoire Naturelle (which hosts the event), IDDRI, the Centre A. Koyré de recherche en histoire des sciences et des techniques and the RUCHE (réseau universitaire de chercheurs en histoire environnementale).

It will address the transformation and the plurality of scientific framings of biological diversity since the late 19th century and analyse the changing ways of measuring, representing, modelling and managing biodiversity. A focus will be given to the plurality of scientific cultures that framed and reframed the conservation motto in national and international contexts (North and South), and on dynamics of co-production of scientific knowledge and conservation policies.

Lucien Chabason (IDDRI's Deputy Director) will contribute on the subject "Mobilizing science for decision: the IPBES (Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Functioning)".
