Espace boise de l’ecoferme de lokoli (sinematiali, nord de la Cote d’Ivoire) : un Cas de compensation ecologique

Abstract

When ecosystems are well managed, they are carbon sinks. The objective of this study is to know the state of the plant biodiversity of the wooded area of the Lokoli Ecofarm and its contribution to the regulation of the climatic regime, with a view to better conservation decision-making.A floristic inventory made it possible to determine the diversity and the floristic composition of the ligneous plants in the different Ecofarm habitats. Dendrometric measurements were carried out to determine the structural profile and the sequestered carbon stock of each habitat. The floristic study made it possible to identify 63 woody species divided into 251 classified into 22 families. The open forest has proven to be the richest in species and the most diverse. The structure in diameter classes reveals that the different biotopes are dominated by young tree stems, with a strong tendency to regenerate. The amount of carbon contained in the total biomass was found to be greater in the fallow (8.87 t / ha) than in the open forest (6.53 t / ha) and savannah (6.88 t / ha). The sequestered atmospheric carbon is estimated at 108.98 t / ha in total, for an economic value varying from 27,799.34 to 124,279.41 euros depending on the different carbon markets. In addition, this study showed that fallow significantly contributes to increasing the carbon sequestration potential of the Ecofarm.
