The vegetation and the afforestation of agricultural land non-forest represent a potential increase in carbon stocks which could, under certain conditions and within certain limits, compensate part of the emissions resulting from the use of fossil fuels and deforestations. Quantification of stocks of biomass and carbon dioxide contained in agroforestry systems has become an international priority within the framework of the implementation of REDD+ mechanism. Estimates of stocks of carbon in woody biomass, dead organic matter, belowground biomass, litter, herbaceous and lianas plant biomass were incorporated in allometric equation based on non-destructive method. The total carbon stock evaluated in the parkland of Tectona grandis was 207.34 ton/3ha out of which woody biomass accounted for 130.19 ton/3ha belowground biomass (40.4 ton/3ha), dead organic matter (22.85 ton/3ha), litter (9.09 ton/3ha), herbaceous plant biomass (2.28 ton/3ha) and lianas (2.53 ton/3ha). The aboveground biomass therefore contributed approximately 62.80 % of the total stock of carbon assessed. This show the considerable contribution of Tectona grandis parkland to climate change mitigation in Cameroon.

La cartographie du stock de carbone permet d’enrichir les connaissances mais aussi la comparaison des diverses transformations du couvert végétal sur l’évolution du stock. La présente recherche vise à cartographier la variabilité spatiale du stock de carbone forestier dans la Réserve de Biosphère Transfrontalière du W au Nord-Bénin. Le modèle de régression non linéaire a permis de prédire la distribution spatiale de la biomasse et du carbone à partir des valeurs de NDVI. Il résulte de cette méthode que la biomasse totale produite dans les unités de végétation de la RBTW a été estimée à 39 988 935,73 tonnes. La quantité totale de carbone correspondante est de 19 474 611,70 tonnes. Concernant la quantité de dioxyde de carbone accumulée, elle a été évaluée à 71 471 824,94 tonnes. Par ailleurs, la quantité de biomasse estimée par placeau oscille entre 2,71 et 172,82 t/ha. Le potentiel de séquestration de carbone dans les savanes boisées et arborées fait respectivement 1,81 et 1,24 fois celui enregistré en moyenne dans la RBTW. Les savanes arbustives et les friches sont les unités qui piègent le moins de dioxyde de carbone soit 18 % et 2 % du total de CO2. Sur l’ensemble du secteur d’étude, la quantité de carbone enregistrée varie de 35,80 à 54,32 t/ha avec une moyenne de 41,24 ± 4,08 t/ha. La quantité moyenne dans le Parc est de 40,42 ± 2,85 t/ha alors qu’elle est de 41,95 ± 4,78 t/ha pour la périphérie. La distribution spatiale de la biomasse et du carbone montre que les fortes quantités de biomasse et de carbone sont enregistrées particulièrement au sud-ouest de la RBTW. Mapping of carbon stock allows for a better understanding but also for the comparison of various vegetation cover transformations on the evolution of the stock. The present research aims to map the spatial variability of forest carbon stock in the W Transboundary Biosphere Reserve in northern Benin. The non-linear regression model was used to predict the spatial distribution of biomass and carbon from NDVI. As a result of this method, the total biomass produced in the RBTW vegetation units was estimated to be 39,988,935.73 tons. The corresponding total amount of carbon is 19,474,611.70 tons. Regarding the amount of carbon dioxide accumulated, it was estimated at 71,471,824.94 tons. Furthermore, the estimated amount of biomass per plot varies between 2.71 and 172.82 t/ha. The carbon sequestration potential of these two units in woodlands and shrub savannahs is respectively 1.81 and 1.24 times that recorded on average in the RBTW. Shrub savannahs and wastelands are the units that sequestrate the least carbon dioxide at 18% and 2% of total CO2. Over the entire study area, the amount of carbon recorded ranges from 35.80 to 54.32 t/ha with an average of 41.24 ± 4.08 t/ha. The average amount in the Park is 40.42 ± 2.85 t/ha while it is 41.95 ± 4.78 t/ha for the periphery. The spatial distribution of biomass and carbon shows that high amounts of biomass and carbon are recorded in the south and particularly in the southwest of the RBTW.

“…Otros factores, tal como eventos naturales extremos (e.g. tormentas, huracanes), también podrían tener un impacto en el flujo de carbono almacenado en la necromasa (Ifo, Koubouana, Jourdain, & Nganga, 2015). En el caso de los bosques del sur del Huila, la baja tasa de descomposición y la abundancia de árboles grandes que al morir aportan gran cantidad de detritos gruesos, puede ser un factor que determina el patrón observado.…”

Biomass and total carbon in oak forests of Southern Colombian Andes: contributions to the REDD+ project-wide approach. Carbon estimations in tropical forests are very important to understand the role of these ecosystems in the carbon cycle, and to support decisions and the formulation of mitigation and adaptive strategies to reduce the greenhouse emission gases (GHG). Nevertheless, detailed ground-based quantifications of total carbon stocks in tropical montane forests are limited, despite their high value in science and ecosystem management (e.g. REDD+). The objective was to identify the role of these ecosystems as carbon stocks, to evaluate the contribution of the pools analyzed (aboveground biomass, belowground biomass and necromass), and to make contributions to the REDD+ approach from the project scale. For this study, we established 44 plots in a heterogeneous landscape composed by old-grown forests located in the Southern Colombian Andes. In each plot, all trees, palms and ferns with diameter (D) ≥ 15 cm were measured. In the case of palms, the height was measured for 40 % of the individuals, following the Colombia National Protocol to estimate biomass and carbon in natural forests. National allometric equations were used to estimate aboveground biomass, and a global equation proposed by IPCC was used for belowground biomass estimation; besides, palms' aboveground biomass was estimated using a local model. The necromass was estimated for dead standing trees and the gross debris. In the latter case, the length and diameters of the extremes in the pieces were measured. Samples for wood density estimations were collected in the field and analyzed in the laboratory. The mean total carbon stock was estimated as 545.9 ± 84.1 Mg/ha (± S.E.). The aboveground biomass contributed with 72.5 %, the belowground biomass with 13.6 %, and the necromass with 13.9 %. The main conclusion is that montane tropical forests store a huge amount of carbon, similar to low land tropical forests. In addition, the study found that the inclusion of other pools could contribute with more than 20 % to total carbon storage, indicating that estimates that only include the aboveground biomass, largely underestimate carbon stocks in tropical forest ecosystems. These results support the importance of including other carbon pools in REDD+ initiatives' estimations. Rev. Biol. Trop. 64 (1): 399-412. Epub 2016 March 01.
