Current Project(s)

I am conducting research within the projects WeiTiMo and SAGE, focusing on sustainable land use, vegetation dynamics, and ecosystem services in changing rural landscapes. My research explores virtual fencing as a tool for flexible land and grazing management and investigates solar grazing as an innovative strategy for combining renewable energy production with grazing livestock systems. Through this research, I aim to contribute to the development of sustainable, pasture-based land-use concepts.

 

 

Research Interests 

• Virtual fencing technologies for grazing livestock
• Sustainable grazing systems
• Use of GPS-based movement data from grazing animals
• Analysis of animal behavioural patterns
• Water management
• Research on peatlands and peatland management
• Climate change adaptation strategies
• Biodiversity in grassland ecosystems
• Interactions between grazing animals and vegetation
• Environmentally friendly grassland management and sustainable land use practices
