Abstract
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.
