Prof. Dr. Lars Ribbe

Lars Ribbe is a professor for integrated land and water resources management and director of the Institute for Technology and Resources Management in the Tropics and Subtropics (ITT), TH Köln (University of Applied Sciences) since 2009. His work areas include river basin assessment, modelling and management and he is specifically interested in developing knowledge systems which help decision makers to cope with prevailing water resources related challenges like water scarcity and drought, water use efficiency and water allocation. Recently he has been involved in bridging scientific and sectoral approaches in the context of the water, energy and food security Nexus by forming an interdisciplinary group on that matter at TH Köln. After obtaining degrees in Chemistry (University of Bremen) and Master of Engineering (Cologne University of Applied Sciences) he received his PhD (Dr.rer.nat) in the field of Hydro-informatics at Friedrich Schiller University Jena, Germany. At ITT he is coordinating international master programs with relation to water and environmental sciences together with Jordan University, Vietnam Academy of Applied Sciences and the Autonomous University San Luis Potosi, Mexico as part of an international university network involving over 15 universities from around the globe. Furthermore, his current research is related to a systematic analysis of river basins with the aim to provide water governance support in Vietnam, Jordan, Chile, Brazil and the Nile Basin.
