More people equal more trees in semi-arid West Africa - Our new study published in Nature Geoscience questions ‘received wisdom’ as concerns the relationship between human agency and woody vegetation of West Africa. We demonstrate that in low-rainfall areas woody cover is denser in cultivated areas than in savannas, and close to settlements rather that … Continue reading Tree cover promoted in semi-arid Sahelian farms – new publication in Nature Geoscience
Our new study uses unprecedented data sources to measure vegetation carbon stock dynamics at continental scale. The study demonstrates that over the African continent, the net carbon balance is negative for 2010-2016, and that most of the carbon losses occurred in dryland savannahs. The results were published in the journal Nature Ecology and Evolution. The … Continue reading A new tool to monitor aboveground vegetation carbon stocks: first application to the African continent
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!

Do Agrometeorological Data Improve Optical Satellite-Based Estimations of the Herbaceous Yield in Sahelian Semi-Arid Ecosystems? Remote Sens. 2016, 8, 668. Quantitative estimates of forage availability at the end of the growing season in rangelands are helpful for pastoral livestock … Continue reading Integrating meteorological data in biomass prediction models
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
Our latest article is not located in the Sahel, however, the method to assess the future persistence of vegetation trends is highly interesting in the context of ecosystem stability and resistance. The article is open access and freely available. Tong, Xiaowei; Wang, Kelin; Brandt, Martin; Yue, Yuemin; Liao, Chujie; Fensholt, Rasmus. 2016. "Assessing Future Vegetation … Continue reading Assessing Future Vegetation Trends and Restoration Prospects in the Karst Regions of Southwest China
