The emission of greenhouse gases can be reduced either by reducing the rate at which they are emitted into the atmosphere or by increasing the rate at which gases are removed from the atmosphere through carbon sinks. In this context, the evaluation of biomass and carbon sequestration potential by the Mambala forest massif to the east of Kikwit was studied. The general objective is to estimate the contribution level of the forest massif to the regulation of the climate system through a diagnosis of the quantities of sequestered carbon. The floristic inventory was carried out on an area of 1 ha delimited in the Mambala forest, made up of 5 strips of 100 m x 20 m within which, the dbh ≥10cm of the trees were measured. The non-destructive method was employed and allometric equations developed by authors were used for this purpose. 439 trees with a diameter at breast height greater than or equal to 10 cm were inventoried, identified into 56 species, divided into 28 families, the most represented of which is that of Fabaceae. The carbon contained in the biomass is 616.93t/ha. The quantity of sequestered carbon and the carbon equivalent obtained were respectively 317.05 and 984.58t/ha; the basal area was 52.07m2/ha. Based on these results, we can affirm that this ecosystem is a real natural carbon sink which must be well managed, because it can contribute to the mitigation of greenhouse gases if it is well managed.

Abstract
The emission of greenhouse gases can be reduced either by reducing the rate at which they are emitted into the atmosphere or by increasing the rate at which gases are removed from the atmosphere through carbon sinks. In this context, the evaluation of biomass and carbon sequestration potential by the Mambala forest massif to the east of Kikwit was studied. The general objective is to estimate the contribution level of the forest massif to the regulation of the climate system through a diagnosis of the quantities of sequestered carbon. The floristic inventory was carried out on an area of 1 ha delimited in the Mambala forest, made up of 5 strips of 100 m x 20 m within which, the dbh ≥10cm of the trees were measured. The non-destructive method was employed and allometric equations developed by authors were used for this purpose. 439 trees with a diameter at breast height greater than or equal to 10 cm were inventoried, identified into 56 species, divided into 28 families, the most represented of which is that of Fabaceae. The carbon contained in the biomass is 616.93t/ha. The quantity of sequestered carbon and the carbon equivalent obtained were respectively 317.05 and 984.58t/ha; the basal area was 52.07m2/ha. Based on these results, we can affirm that this ecosystem is a real natural carbon sink which must be well managed, because it can contribute to the mitigation of greenhouse gases if it is well managed.

Abstract: (french)
L’émission de gaz à effet de serre peut être réduite soit en diminuant le taux auquel ils sont émis vers l’atmosphère soit en augmentant le taux auquel les gaz sont retirés de l’atmosphère au travers les puits carbones. Dans ce contexte, l’évaluation de la biomasse et du potentiel de séquestration de carbone par le massif forestier de Mambala à l’Est de Kikwit a été étudié. L’objectif général est d’estimer le niveau contributif du massif forestier à la régulation du système climatique à travers un diagnostic des quantités de carbone séquestré. L’inventaire floristique s’est réalisée sur une surface de 1 ha délimité dans la forêt de Mambala, constitué de 5 bandes de 100 m x 20 m au sein desquelles, le dbh ≥10cm des arbres ont été mesuré. La méthode non destructrice a été employée et des équations allométriques développées par des auteurs ont été utilisées à cet effet. 439 arbres à diamètre à hauteur de poitrine supérieur ou égal à 10 cm ont été inventoriées, identifier en 56 espèces, réparties 28 familles dont la plus représentée est celle des Fabaceae. Le carbone contenu dans la biomasse est de 616,93t/ha. La quantité de carbone séquestré et l’équivalent carbone obtenus ont été respectivement de 317,05 et 984,58t/ha; la surface terrière a été de 52,07m2/ha. Partant de ces résultats, nous pouvons affirmer que cet écosystème est un véritable puits naturel de carbone dont il faut bien gérer, car il peut contribuer à l’atténuation de gaz à effet de serre s’il est bien géré.
