Global challenges require the most robust evidence for the best possible responses - which is also key to conserve, restore and sustainably use biodiversity. So, it is vital to include as many perspectives, from as many parts of the world as possible, to understand the full picture, and to ensure that the results are used in every part of the globe. In this episode, we explore why some regions are less engaged in the IPBES processes, and what is being done to address this challenge. Rob talks to Dr. Axel Paulsch, Geo-Ecologist from the University of Bayreuth in Germany and Chair of the Institute of Biodiversity Network about the work they are doing in Eastern Europe and Central Asia; as well as to Dr. Isimemen Osemwegie – Programme Coordinator at CABES, an organization working to research and protect biodiversity in West, Central and East Africa.
