The inventory of the carbon (C) pools in Africa's ecosystems is not well documented, although it is crucial to support climate mitigation policies. We quantified the C stocks in plant biomass, woody necromass, litter and soil (0-30 and 30-100 cm) for the five main land uses - forest, tree plantation, young and adult palm groves, croplands - of Ferralsols on the Allada plateau in southeast Benin. Forests have the highest total C stocks (389 +/- 54 Mg C ha(-1)) compared with other land uses (222 +/- 33, 154 +/- 6, 105 +/- 2, 77 +/- 3 Mg C ha(-1) in tree plantations, adult palm groves, young palm groves and croplands, respectively). The C stocks are higher in the biomass than in the soil (0-100 cm), e.g. in the forest, stocks were 279 +/- 54 Mg C ha(-1) in the biomass versus 83 +/- 2 Mg C ha(-1) in the soil. Differences of soil C stocks between land uses are low (approximate to 28 Mg C ha(-1)) and concentrated in topsoils. The structure and species diversity of the forest partly explained the variability and the high C biomass compared to tree plantations. Type of forest and plantations is important to consider in conserving C stocks in landscapes.
