Working Group Water Research
Working Group on Geographical Water Research and Education for Sustainable Land Use
Our Water research is based on river basins or watersheds. River basins or watersheds are natural units that allow us to analyze water cycle and water use in a quantitative way. It is an ideal scope to determine mass-balances inside the water cycle and monitor changes over time and to study changes from the headwaters all the way downstream. Based on a Watershed and people living inside the watershed, human activity can be linked with natural responses and enables the analysis of the interactions between human activities and the natural environment.
The watershed as an integration tool allows us to determine the cumulative effect from all activities and natural processes. Moreover the watershed based analysis facilitates the assessment of a variety of ecosystem functions.
In general our work group follows the idea of integrated watershed resources management (IWRM) in education and research which addresses ecological factors, societal needs and environmental topics in a more holistic manner. As scientists we take part in a dialogue with multiple stakeholders and integrate them into our modeling, assessment and decision-making processes (e.g. integrating local stakeholders and their knowledge inside our regional projects in Vietnam, Iran or Mongolia). Although the multi-stakeholder involvement and process is a major critique of IWRM because of its time consuming part we try to follow this approach in our work as far as possible (knowing that including all actors in managing water resources is unrealistic). We try to train the students to use the best current knowledge and initiate management strategies that we think are most suitable (within the meaning of "adaptive management"). Therefore we integrate our students into running research projects and teach them in watershed modelling using a variety of models, GIS systems and integration of Remote Sensing data.
Knowledge about models help us to understand processes and the amount of change. Further they help to determine which of the processes are most important to change. Using a variety of models and GIS-based data we try to link our modelling more and more to ecosystem modelling and sustainable land use.
Finally we try to solve a little bit the problem of the disconnect between land use, water and the complex human-environmental interface.
