Paper on Forest Ecology and Management
Christian Levers developed, together with several collaborators in VOLANTE, a forest harvesting intensity metric and analyzed the factors that explain the spatial pattern of forest harvesting across Europe.

New paper in Global Environmental Change by postdoctoral researcher Daniel Müller et.al.
This paper is a product from the I-REDD+ project. In essence, it challenges the widely held view that land-system changes can be reliably predicted in dynamic tropical landscapes. We demonstrate how sudden events and gradual changes in underlying drivers caused rapid, surprising and widespread land-system changes in a range of case studies in Southeast Asia...
Paper accepted by IEEE J-STARS: Mapping annual land use and land cover changes using MODIS time series. Doctoral researcher He Yin et.al., geomatics Lab.
This manuscript aims to characterize changes between land cover/use types based on annual time series of machine learning derived land cover probabilities. We used the temporal segmentation algorithm MODTrendr to identify trends and changes in the probability time series that were associated with land cover/use conversions. Four land conversion types were mapped and tested: conversions between forest and grassland, conversions between cropland and grassland. The results reveal good performance of our approach - though the mapping accuracy varies among different change classes. We presented for the first time an approach that combines probabilities derived from machine learning with time series based analysis for land cover/use change analysis at MODIS scale...
