Tree cover promoted in semi-arid Sahelian farms – new publication in Nature Geoscience

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

Recent woody vegetation trends in Sahel

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

What Four Decades of Earth Observation Tell us about Land Degradation in the Sahel

From: Mbow, C.; Brandt, M.; Ouedraogo, I.; de Leeuw, J.; Marshall, M. What Four Decades of Earth Observation Tell Us about Land Degradation in the Sahel? Remote Sens. 2015, 7, 4048-4067. Land degradation mechanisms are related to two main categories, one related to climate change and one associated with local human impact, mostly land use … Continue reading What Four Decades of Earth Observation Tell us about Land Degradation in the Sahel

New project started: BICSA – Biophysical Changes in the Sahel

To continue my research about the Sahel area, I received a Marie Curie Individual Fellowships (Call: H2020-MSCA-IF-2014) for the coming 2 years. The new project which started on May the 1st is named BICSA – Biophysical Changes in the Sahel: Ground and Satellite Based Evidence Across Scales and Disciplines. This is the abstract of the … Continue reading New project started: BICSA – Biophysical Changes in the Sahel

Ground- and satellite-based evidence of the biophysical mechanisms behind the greening Sahel

Making use of 27 years of ground measurements, we were able to find evidence of the role of trees and grass on the greening of the Senegalese Sahel. This was made possible by a close collaboration with our colleagues from the CSE, the Centre de Suivi Ecologique in Dakar. Moreover, woody species abundance data provided … Continue reading Ground- and satellite-based evidence of the biophysical mechanisms behind the greening Sahel
