Our article in Nature Ecology & Evolution got some media attention, both in the Danish and the international press. Africa has become greener in the last 20 years at Science Nordic Global greening may soak up less carbon dioxide than projected at New Scientist The forests won’t fix our CO2 problem — in fact, they’ll … Continue reading Our research in the media
Our fantastic team had some new publications within the past half year, they are all worth to have a look: Xiaoye Tong, Martin Brandt, Pierre Hiernaux, Stefanie Herrmann, Feng Tian, Alexander Prishchepov, Rasmus Fensholt. Revisiting the coupling between NDVI trends and cropland changes in the Sahel drylands: A case study in western Niger. Remote Sensing … Continue reading New publications!
With our last article published, we are closing the special issue on land degradation for the open access journal Remote Sensing and I want to share some experiences here. In total, 24 articles were submitted, 13 of them were published, 6 rejected without going to review, and 5 were rejected after review. So we have … Continue reading Publishing in the open access journal Remote Sensing (MDPI)

DIE ERDE – Journal of the Geographical Society of Berlin, 2016, 147, 2. This paper raises awareness of data scale issues in environment migration research, for example the declining station … Continue reading New publications
Here's a simple way of processing MODIS: downloading, extracting the bands from HDF as GEOTIFF, merging tiles and reprojecting. Area extraction, NDVI calculation, cloud filtering and more can be done in GRASS for example. It's Linux based, but can easily used in Windows. My way might not be the most elegant, but it's fast and … Continue reading Downloading and processing MODIS with fast and free tools
Our new paper looks at recent dynamics in woody vegetation in Sahel and finds some interesting patterns which are mainly controlled by human population density. Martin Brandt, Pierre Hiernaux, Kjeld Rasmussen, Cheikh Mbow, Laurent Kergoat, Torbern Tagesson, Yahaya Ibrahim, Abdoulaye Wele, Compton J. Tucker, Rasmus Fensholt. Assessing woody vegetation trends in Sahelian drylands using MODIS … Continue reading Recent woody vegetation trends in Sahel
