etude vise a determiner le stock de carbone organique dans les plantations de Acacia auriculiformis des forets classees (Ouedo et Pahou) afin d’apprehender leur contribution a l’attenuation des changements climatiques. La methodologie d'estimation du carbone est basee sur les recommandations faites par l'IPCC et celle de FAO ainsi que des equations allometriques. Les donnees climatiques ont ete collectees a la station meteorologique d’Agonkanme. Selon les differents compartiments, les resultats revelent que le stock de carbone est plus eleve dans le tronc : 78,17%; les branches : 19,50% et les feuilles: 2,33%. Le potentiel de sequestration du carbone du sol varie entre 31,46% et 70,99% en fonction des types de sol. Les stocks de carbone eleves sont obtenus dans la plantation de 2,5 ans sur sol hydromorphe a Pahou (106,23 ± 38,39 tC/ha) contre 77,77 ± 5,47 tC/ha pour celle de 2 ans sur sol ferralitique a Ouedo. Il y a une correlation fortement negative et significative (r = - 0,931, P < 0,001) entre la temperature et le stock de carbone. Les fortes temperatures observees sont le resultat de la faible sequestration de carbone et vice-versa. Mots cles : Sequestration de carbone, essences exotiques, attenuation des changements climatiques, English Title : Benin Estimation of the organic carbon’s stock in the plantations of Acacia auriculiformis A. Cunn. ex Benth. of the classified forests of Pahou and Ouedo in the South of Benin The reduction by trees of carbon dioxide is an important ecosystem activity. The present study aimed at assessing the organic carbon stock in the plantations of Acacia auriculiformis of the classified forests of Ouedo and Pahou in order to better understanding their contribution to mitigating climate changes. The method described by IPCC (2007), FAO (2002) associated with allometrics equations were used for the carbon stock estimation. The climate datas used, were collected at the Meteorological Station of Agonkanme. According to the different components of trees, results shown that the trunk has the highest rate of carbon stock: 78.17%; branches: 19.50% and leaves: 2.33%. The potential of soil carbon’s sequestration varies between 31.46% and 70.99% depending on soil types. The high-level stocks of carbon are obtained in 2.5 years old on a hydromorphic soil plantation in Pahou (106.23 ± 38.39 tC / ha) compared with 77.77 ± 5.47 tC / ha from the 2 years old plantation on a ferralitic soil in Ouedo. There is a high negative and significant correlation (r = - 0.931, P <0.001) between temperature and carbon’s stock. The high temperatures observed are the result of low carbon’s sequestration. Keywords : Carbon sequestration, exotic species, climate change mitigation, Benin.
