Integrated Modelling and Optimization
The work of our group is focussed on a) the description of the impact of land use and management changes on water and matter balance and ecosystem services as well as b) the identification and mitigation of trade-offs among land use, ecosystem services and biodiversity. In addition, we also tackle methodological questions in modelling and simulation such as quantification and specification of scale dependencies in process description, uncertainty in data and models as well as developing optimization tools to support landscape and environmental management strategies. Our toolset of models ranges from process-based to statistical and optimization algorithms.
- Data-based modelling approaches to identify parsimonious modelling approaches and to derive optimised monitoring strategies.
- Modelling and simulation of complex interactions and trade-offs based on problem-specific and process-oriented, but also on empirical and statistical approaches. Thus we aim at a range of different model approaches that serve as a landscape modelling toolset.
- Validation, further development and test of models. For this we use information from monitoring and mapping, remote sensing and existing databases.
- Techniques of optimization and uncertainty analysis are used to test models, and derive and test management strategies.
