The West African Sahel is a transitional region located between the dry Sahara Desert in the north and the wetter savannah subregion in the south. It has a unique climate that has received a lot of research attention due to its variability and susceptibility to droughts. The average annual rai...
N in the modern-day African Sahel are testament to equatorward expansions of the Sahara desert during the Late Pleistocene. However, the discontinuous nature of dune records means that abrupt millennial-timescale climate events are not always resolved. High-resolution marine core studies have ...
The Sahel region is in sub-Saharan Africa and is a transition zone between the arid Sahara desert to the north and the tropical green forest to the south, covering a surface area of 5.7 million Km2 with a population of about 60 million inhabitants. The vegetation In the Sahel region is co...

Here we map the crown size of each tree more than 3 m2 in size over a land area that spans 1.3 million km2 in the West African Sahara, Sahel and sub-humid zone, using submetre-resolution satellite imagery and deep learning4. We detected over 1.8 billion individual trees (13.4 trees per...
The rainfall in Sahel is highly dependent on the strength and duration of the West African Monsoon whose arrival is caused by development of the Saharan Heat Low in the boreal spring/summer season, and the resulting pressure gradients between the Sahara Desert and the Tropical Atlantic31,32. A...
On PC2, individuals from the Fulani population in Linguère (Senegal) separated out from other Fulani, while on PC3, Fulani populations in Burkina Faso differentiated from the Fulani in Niger, Chad, and Cameroon (Figures 1D and 1E). Heatmaps visualizing matrices of pairwise genetic and ...
The combination of DNA barcoding with spatial modelling can be easily applied to any desert system to address pressing needs for research on biodiversity distribution.doi:10.1007/s10592-021-01331-8Marta SampaioGuillermo Velo-AntónFernando Martínez-Freiría...
