Ecosystem Carbon Storage and Partitioning in Chato Afromontane Forest: Its Climate Change Mitigation and Economic Potential

DOI: 10.22161/ijeab/2.4.41

Abstract:
Forests trap carbon dioxide (CO2) from the atmosphere, store in the form of carbon (C) and regulate climate change. In this study, C storage and climate change mitigation potential of Chato Afromontane forest was assessed from measurement of the major pools including the aboveground biomass, belowground biomass, dead tree biomass, plant litter and soil organic carbon (SOC). The result showed that biomass accumulation was comparatively larger for natural forest than plantations due to maturity, intactness and species diversity. The total C storage capacity of the forest ranged from 107.12 Mg ha-1 for acacia plantation to 453.21 Mg ha-1 for the intact natural forest. The mean C storage capacity by major pools ranged from 1.36 Mg ha-1 for the dead tree C to 157.95 Mg ha-1 for the aboveground C pool. The forest ecosystem accumulated a total of nearly 6371.30 Gg C in the vegetation plus soil to a depth of 60 cm. Conservation of the sacred forest will have an imperative implication to net positive C addition and regulation of climate change.
