Wolfgang Cramer is an environmental geographer and global ecologist and scientific director at the Mediterranean Institute for Biodiversity and Ecology (IMBE), in Aix-en-Provence, Marseille and Avignon (France), since the establishment of the institute in 2012. The scientific contributions by Cramer’s research group (140+ papers) were initially in the area of modelling forest dynamics under climate change. He then began to seek a broader understanding of biosphere dynamics at the global and continental scale, including aspects of natural and human disturbance as well as biodiversity. He has been directing a large European ecosystem modelling project, ATEAM (EU FP5), as well as its companion outreach activity, AVEC. Together, these projects have resulted in the first ever region-specific and comprehensive ecosystem service assessment across Europe, communicated through the scientific literature as well as through an intensive stakeholder dialogue. He is a contributor to the IPCC and the Millennium Ecosystem Assessment. He is Chair of the Science Committee of ecoSERVICES and serves regularly as advisor of the German government and the EU Research Directorate.
