Abstract

During the work, localities such as: Calbacier, Maton, Font-Tortue, Vincent-dron and Boino were identified by their reputation in cacao culture to collect data that were collected through the five (5) localities, of which 30 cacaoyers per locality were randomly selected within a radius of two-thirds of a hectare (10000m2), making a total of two hundred and forty (240) cacaoyers measured by the method described by Purata [1]. To estimate biomass, dendrometry parameters such as (H and D) were selected and then the allometric equation of Chave et al. [2] was used. Therefore, sequestered airborne carbon was projected by biomass, the result of which is multiplied by the IPCC constant [3]. After calculation, the results found for the space-sequestered carbon were respectively: Calbacier 4,665tC/ha, Maton 2,463tC/ ha and Font-Tortue 4,101tC/ha for the class of 1-year; for the class of 2-years: Calbacier 8,796tC/ha and Maton 6,823tC/ha and for the class of 3-years: a Font-Tortue 7,073tC/ha, Vincent-dron 81,137tC/ha and Boino 2,463tC/ha. In addition to space, the air carbon sequestered over time was estimated and the following results were obtained: Calbacier 1 and 2 years 4,665tC/ha, 8,796tC/ha; Maton 1 and 2 years 2,463tC/ha, 6,823tC/ha and Font-Tortue 1 and 3 years 4,101tC/ha, 7,073tC/ha. Following the different results found in the different localities of different ages, it has been shown that carbons can vary from one locality to another in time and space. In space the equation found is y=-1.013x3 + 14.01x2 - 50.95x + 50.75. R²=0.273 and y=0.254x3 - 2.516x2 + 7.047x + 0.454, R²=0.192 in time.
