“…This is explained by the fact that the closure of older plots negatively influences the carbon reservoir of the herbaceous layer. Our results obtained are similar to that found by Kooke et al [21] in 12year-old, 4-year-old Acacia auriculiformis plantations; 2.5 years; 6 years and 2 years with 3.08 ± 0.04 tC/ha respectively; 3.13 ± 0.02 tC /ha; 3.16 ± 0.03 tC/ha; 3.07 ± 0.03 tC /ha and 3.16 ± 0.01 tC/ha and in Terminalia superba plantations (3.13 ± 0.03 tC/ha) in southern Benin. However, they remain above the range 0.25 ± 0.002 to 1.25 ± 0.002 tC/ha reported by Awe et al [8] in Tectona grandis Agroforestry parkland (Northern Region of Cameroon).…”

The present study aims to quantify carbon storage in different biomass pools of Psidium guajava agroecosystems in the northern region of Cameroon in order to understand their contribution to climate change mitigation. The destructive and non-destructive methods were used according to a random complete Fisher block device with 4 repetitions. The results obtained show that the average total carbon stock of Psidium guajava agroecosystems in the northern zone of Cameroon is 44.44 ± 4.96 tC/ha. The total carbon stock varies by region; in the Adamawa region (46.30 ± 4.91 tC/ha); North (46.34 ± 4.93 tC/ha) and Far North (40.69 ± 4.98 tC/ha). These results show the considerable contribution of Psidium guajava agroecosystems in the fight against the mitigation of climate change in the Septentrion zone of Cameroon.

“…According to Schlesinger and Palmer (2000), Amundson (2001), soil organic carbon or organic matter stocks result from a balance between inputs (mostly plant residues) and losses (mostly through microbial decomposition and transfer by erosion). According to the work of Kooke et al (2019), the carbon stock also varies according to soil type and climatic conditions. Montagnini Albrecht and Kandji (2003) which are 95 t/ha for the average value and 228 t/ha for the maximum value in Acacia auriculiformus agroforests.…”

This study aims to assess the organic carbon stock and the amount of organic carbon sequestered in the soils of Foumban, in order to facilitate climate change mitigation policies. To achieve this objective, ninety soil samples were collected from a depth of 0-30cm from the reference soil groups identified in the study area and transported to the laboratory where bulk density and organic carbon analyses were carried out to estimate the SOC stock. The SOC stock and carbon quantity calculations showed that the carbon stock in the soils of the study area varies from 64.10 t/ha in FRAGISOLS (plaggic) cambic to 116.52 t/ha in UMBRISOLS pretic, with an overall average of 88.95 ± 18.61 t/ha. The total amount of organic carbon stored in the soils is estimated to be about 85.79×10− 4 GT. It varies from 1.30×10− 4 GT in cambic hortic FERRALSOLS (plaggic) on trachytes to 17.13×10− 4 GT in chernic arenic UMBRISOLS. The variation in carbon stock in the study area would be due to the variation in the density of the vegetation cover. The input of organic amendments would contribute to the increase of organic carbon stocks in these soils.

La forêt classée de l’Ouémé supérieur au Centre-Bénin est un potentiel puits de carbone en dépit des pressions d’origines anthropiques qui menacent la plupart des écosystèmes forestiers. Cette recherche visait à cartographier la biomasse forestière et le stock de carbone séquestré par les formations végétales de la forêt classée de l’Ouémé supérieur au Bénin. A cet effet, un inventaire forestier a été réalisé dans 73 placeaux circulaires de 18 m de rayon suivant le protocole de l’Inventaire Forestier National (IFN). Les principales données collectées étaient le diamètre et la hauteur des arbres. Les images landsat OLI-TIRS de 2018 à travers le NDVI ont été utilisées en combinaison avec les données de l’inventaire forestier in situ pour la spatialisation de la biomasse et du carbone séquestré. Les résultats obtenus ont révélé que la biomasse totale produite par les arbres dans la forêt classée de l’Ouémé supérieur, avoisine 13 035 694 tonnes avec une quantité totale de carbone séquestrée évaluée à 6 348 383 tonnes. La distribution spatiale de la biomasse et du carbone ont montré de plus fortes quantités de biomasse et de carbone séquestré à l’intérieur de la forêt classée comparativement aux périphéries surtout les zones qui sont situées le long des routes aménagées. Il est alors important d’entreprendre les actions de conservation des formations forestières en vue d’accroître leur potentiel de séquestration de carbone dans l’atténuation des effets des changements climatiques au Bénin. English title: Mapping of forest biomass and assessment of sequestered carbon in the forest reserve of upper Ouémé in Central Benin The Upper Ouémé gazetted forest in Central Benin is a potential carbon sink despite the anthropogenic pressures that threaten most forest ecosystems. This research aims to map the forest biomass and carbon stock sequestered by plant communities in the Upper Ouémé classified forest in Benin. To this end, a forest inventory was carried out in 73 circular plots of 18 m radius following the protocol of the National Forest Inventory (IFN). The main data collected were tree diameter and height. The 2018 OLI-TIRS landsat images through NDVI were used in combination with the in situ forest inventory data for the spatialization of biomass and sequestered carbon. The results obtained show that the total biomass produced by trees in the Upper Ouémé classified forest is around 13 035 694 tonnes with a total amount of sequestered carbon estimated at 6 348 383 tonnes. The spatial distribution of biomass and carbon shows higher amounts of biomass and carbon sequestered inside the gazetted forest compared to the periphery, especially in areas that are located along developed roads. It is therefore important to undertake conservation actions in forest in order to increase their carbon sequestration potential in mitigating the effects of climate change in Benin.
