The Global Mountain Biodiversity Assessment Network was initiated by the Swiss Academy of Sciences and inaugurated by DIVERSITAS in 2000 in fulfillment of Agenda 21. The network's activities were officially taken up by convening the First International Conference on Mountain Biodiversity in Rigi-Kaltbad LU, Switzerland in September 2000. The research network focuses on biological richness, its function and change at the high elevation end of the biosphere. The Global Mountain Biodiversity Assessment (GMBA) is a cross-cutting network of DIVERSITAS with the task to explore and explain the great biological richness of the mountains of the world. The Global Mountain Biodiversity Assessment (GMBA) is a global network on mountain biodiversity research of DIVERSITAS (Paris, F), an international global change research programme on biodiversity sciences.
