Dr. Joshua Ntajal is a Research Fellow and member of the Ecohydrology and Water Resources Management research group (AG-EVERS) at the Department of Geography, University of Bonn, Germany. Dr. Ntajal holds a Doctorate in Geography from the University of Bonn, Germany, where he explored the interactions among land use dynamics, surface water systems, and human health risk pathways. His research focus and teaching expertise covers a wide range of interdisciplinary domains, including climate change modeling, climate change and human security, land use, hydrological modeling, geospatial data analysis, water quality, integrated water resources management, complex system dynamics, health Geography, one-health, planetary health, and integrated flood risk management in the context of Sub-Saharan Africa. He also served as a cherished reviewer for many renowned scientific journals. Before joining MIASA as a research fellow and co- convenor of the Interdisciplinary Fellow Group (IFG 10), he worked extensively on hydrological modeling under climate change and land use scenarios in large transboundary river basins in West Africa, as part of building human and institutional capacities towards collaborative and sustainable flood risk management.
