Research fields: Spatial Environmental Quality

• Quaternary geology (analysing and modelling of landscape dynamics, fluvial systems)

• Geomorphology (modelling landscape processes, sediment geochemistry)

• Soil Science (soil-landscape system characterisation and impact of land use on soil dynamics)

• Land evaluation, Land use cover change modelling (spatially explicit modelling of land use/cover change)

• Coupled Human-Ecological systems (modelling of feedbacks and system analysis)
• Transition towards sustainable development and Competing Claims
