My research work is based on process and trait-based modelling of savanna landscapes (using the ecohydrological process model EcoHyD). Moreover, we analyse key plant and ecosystem traits and processes with respect to their importance for ecohydrological feedbacks and ecosystem functioning. Besides the modelling approach methods used to analyse ecosystem dynamics include the analysis of remote sensing imagery and field data (plant traits).

The geographic focus of this research is on Namibian savanna rangelands. Key research questions are:

• How can semi-arid and arid savannas be managed (w.r.t. grazing of cattle and game) sustainably under climate change?
• Are there key ecohydrological feedback loops and plant/ecosystem traits that can help identifying sustainable management strategies?
