Researcher
Dr. Markus Venohr is a Senior Scientist and Research Group Leader at the Leibniz-Institute of Freshwater Ecology and Inland Fisheries (IGB) in Berlin, Germany, where he leads the River System Modelling research group within Department 1 (Ecohydrology and Biogeochemistry). He holds a PhD from Humboldt-University Berlin and has been with IGB since completing his doctorate, first as a Post-doc (2006-2008) and then as a Senior Scientist since 2009. Dr. Venohr received his PhD from Humboldt-University Berlin (2001-2005), following studies in Geography, Meteorology and Oceanography at Christian-Albrechts University Kiel (1996-2000), and initial Geography studies at Ruhr-University Bochum (1994-1996). His research focuses on nutrient fluxes from land to sea , nutrient transport and transformation , biotic-abiotic coupling , river system modelling , climate change and management adaptation , and recreation ecology . Dr. Venohr specializes in understanding how human activities impact freshwater systems, particularly through nutrient pollution from agricultural and urban sources, and develops models to assess and predict these impacts. His work bridges the gap between scientific research and practical water management solutions. Dr. Venohr's recent publications demonstrate a strong focus on nutrient modeling (particularly the AGRUM-DE framework), water quality assessment across scales from Berlin waterways to the Danube basin, and the impacts of human activities on freshwater ecosystems. His research increasingly addresses urban pollution sources, recreation ecology impacts, and climate adaptation strategies, with significant international collaborations evident in his work on topics ranging from the Kakhovka Dam destruction to nicotine contamination in surface waters.

The group works closely with water management authorities across Germany and Europe to translate scientific findings into practical management solutions, particularly regarding nutrient pollution reduction and climate adaptation strategies.
