Greenhouse gas emission from prescribed fires is influenced by vegetation types in West African Savannas.

ABSTRACT: Greenhouse gas (GHG) emissions from prescribed fires are poorly investigated, resulting in a high uncertainty in GHG budgets. Using, a carbon mass balance approach and experimental prescribed fires in 80 plots, this study assessed carbon emissions and established emission factors (EFs) for carbon dioxides (CO₂), carbon monoxide (CO), and methane (CH₄) across climate zones and vegetation types. In grass and shrub savannas, fires could burn intensely due to the lower moisture content and continuous spatial distribution of biomass fuel, causing greater carbon emissions with 1.61 ± 0.13 t C ha^-1 and 1.01 ± 0.13 t C ha^-1, respectively. Despite their low carbon emissions, tree savannas (1658.17 ± 11.13 g kg^-1) and woodlands (1629.94 ± 12.23
