Résumé : Curing the last years in West Africa, the effects of climate change have manifested through an increase in air temperatures and a delay/irregularity of the first rains, which contribute to keeping agricultural land without vegetation cover during several months of the year.Using a modeling approach we explored the impacts of this climatic change on soil C dynamics and on CO2 release to the atmosphere.
