  abstract = {{T}he impact of livestock grazing on soil organic carbon ({SOC}) stocks in the {S}ahel has been poorly documented due to a lack of data from different grazing intensities. {T}his study evaluated {SOC} stocks under four grazing intensities within 0-30 cm soil depth in dry savanna ecosystems of {S}enegal. {I}t also examined possible indirect relationships between grazing and {SOC} through herbaceous species diversity, herbaceous biomass, and carbon-nitrogen ratio. {F}our sites representing high, moderate, light, and no grazing intensity levels were selected. {T}ransect survey methods were used for sampling soil and vegetation data within each of the sites. {D}ata were analyzed using mixed-effects models and piecewise structural equation modeling (p{SEM}). {SOC} stocks were significantly different among the four grazing intensities, and higher stocks were observed with increased intensity. {F}urthermore, high-intensity grazing was shown to reduce the carbon-nitrogen ratio by negatively affecting the diversity of herbaceous species, which indirectly promoted {SOC} stocks. {I}n conclusion, this study found that increased grazing intensity promoted {SOC} stocks both directly and indirectly through herbaceous species diversity.},
