Lena Katharina Öttl is a PhD student assessing the impact of tillage erosion on crop biomass production in the Uckermark region in North-East Germany. The research is in cooperation with the Leibniz Centre for Agricultural Landscape Research ZALF e.V. in Müncheberg. She did her MSc. in Climate and Environmental Sciences at the University of Augsburg and spent one semester at ZALF (working group „Landscape Pedology“; former „Institute of Soil Landscape Research“). There, she started working on her research topic which was continued in her master thesis. The thesis deals with erosion feedbacks on the Enhanced Vegetation Index (EVI) of arable crops in a climate-sensitive catchment in the hummocky young moraine landscape of North-East Germany.
