Abstract
- 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<superscript>−1</superscript>) compared with other land uses (222 ± 33, 154 ± 6, 105 ± 2, 77 ± 3 Mg C ha<superscript>−1</superscript> 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<superscript>−1</superscript> in the biomass versus 83 ± 2 Mg C ha<superscript>−1</superscript> in the soil. Differences of soil C stocks between land uses are low (≈ 28 Mg C ha<superscript>−1</superscript>) 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. [ABSTRACT FROM AUTHOR]
