Associate Professor

About Me

Maarten Krol is an associate professor in integrated water modelling. He holds a MSc and PhD in mathematical physics from Utrecht University, and has worked as a researcher at the National Institute of Public Health and the Environment (RIVM, Bilthoven, Netherlands), the Potsdam Institute for Climate Impact Research (PIK, Potsdam, Germany) and the Universidade Federal do Ceará (UFC, Fortaleza, Brazil). He joined the University of Twente in 2003 and since contributed to research and education of Civil Engineering and Management.

Water management is about matching natural physical processes and societal aspiration that go along with claims on water systems. From his background in integrated assessment modelling and mathematical physics, Krol is interested in using simulation approaches and scenario analysis to gain insights in this match. At RIVM, he was main modeller in the IMAGE project on global and climate change, resulting in much-cited publications, contributions to IPCC reports and policy reports supporting Dutch representatives in climate negotiations. At PIK and UFC, he was principal investigator in a large bilateral German-Brazilian programme on drought in Northeastern Brazil in the context of climate change, editor of a book on the programme and contributing to policy advice to the State Government of Ceará on drought management. At UT he was principal investigator in a European project on water savings in irrigation and currently contributes to a European project on the water-land-energy-food nexus in EU policies.

    Research

    Main research interests lie in

    • understanding the mutual relations between water availability and water use,
    • assessing the role of interventions on this relation, specifically the role of reservoirs and their management and spatial allocation and characteristics of irrigation,
    • climate change impacts,
    • model-technical aspects of uncertainty assessment and the role of uncertainty in policy analysis
