Marc Leblanc is a professor of hydrogeology at the University of Avignon where he teaches groundwater modelling to Master and undergraduate students. He is a specialist of water resources in arid and semi-arid regions. His research interests focus on the evolution of aquifer systems under the increasing pressure of climate and global changes. He is also leading efforts to develop innovative tools based on remote sensing to support groundwater assessment and modelling studies. His research led him to work in regional groundwater basins of Niger, Chad, Cameroon, Senegal, Benin, Morocco as well as Australia and China. More recently, Marc has been supporting the UNESCO scientific network on groundwater and climate change (GRAPHIC). Marc has co-authored several UNESCO publications on these topics, as well as over 60 scientific papers in international journals and book chapters.
