Changes in the Westward Transport of Saharan Dust From West Africa With Anthropogenic Forcing in the WRF Model

Geophysical Research Letters, Volume 53, Issue 9, 16 May 2026.
Abstract Large uncertainties exist for future westward Saharan dust transport with increasing Greenhouse Gas emissions. We evaluate future changes in westward dust transport at the longitude of 18.6°W and a latitude range of 4°N–30°N using the Weather Research and Forecasting Model (WRF) with the GOCART dust module for the present‐day, with ERA‐Interim

Phenological responses of irrigated rice in the Sahel [PDF]

, 2011
Worldwide rising temperatures are already being observed and are expected to increase within the next decades. In the Sahel cool periods cause yield losses due to spikelet sterility in late sown rice and thus Sahelian rice production systems might ...

Schumpeter au Sahel

, 1993
La formulation "Schumpeter au Sahel" peut à première vue paraître surprenante. Les réflexions et analyses de Schumpeter ont porté sur des phénomènes d'innovations et de développement qui se sont produits dans le contexte de formations sociales (le développement du capitalisme industriel en Europe) sensiblement différentes des situations rurales ...

Toward Closing the Hydroxyl Radical (OH) Budget: Assessing the Feasibility and Uncertainties in Constraining primary OH Production From Space

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 9, 16 May 2026.
Abstract Recent progress in constraining the atmosphere's primary oxidant, the hydroxyl radical (OH), with machine learning (ML) and satellite data raises the intriguing possibility of also constraining individual OH chemical production and loss terms.

Multi‐Model Impacts of Dust on African Air Quality and Mortality Under Regional and Global Anthropogenic Aerosol Changes

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 9, 16 May 2026.
Abstract Decreases in anthropogenic aerosols will reduce fine particulate matter (PM2.5); however, meteorological feedbacks alter dust emissions, modifying air quality gains. We use eight Earth System Models from the Regional Aerosol Model Intercomparison Project (RAMIP) simulations to assess African climate and air quality responses to anthropogenic ...

Labour organisation, commercial income and distribution in arid areas : A study case at Tatki (in the Senegalese Sahel) [PDF]

, 2008
The specificities of the Senegalese pastoral context (mobility, non-equilibrium environment, informal exchanges and scarcity of the resources) required a device of data collecting adapted. The investigations allowed identifying the labour inside pastoral

Desertification Risk: Bibliometric Analysis and Future Research Directions

Land Degradation &Development, Volume 37, Issue 8, Page 3331-3348, 15 May 2026.
ABSTRACT Desertification, driven by climatic and anthropogenic factors, is one of the most pressing global environmental challenges, causing significant economic, ecological, and social consequences. A bibliometric analysis was performed to identify research trends and gaps in the desertification risk topic.

Seasonality and Grazing Exclusions Shape Bird Community Dynamics in West African Drylands

Ecology and Evolution, Volume 16, Issue 5, May 2026.
Seasonal changes, more than grazing exclusions, shape bird community composition in the Sahel region of Burkina Faso. However, grazing exclusions enhanced habitat heterogeneity, supporting regional bird biodiversity and providing seasonal refuges that mitigate the effects of overgrazing.
