This work reports the evaluation of calorific energy content, the agro-biological morphology of gliricida sepium in a derived forest in Ado Ekiti South-western Nigeria and its CO2 absorption capacity. The wood biomass density was found to be 620.15 kg/m3, the calorific energy content 16.67 MJ.kg which was similar to that of green oak wood. A One Tonne Gliricidia Tree has the capacity to sequestrate 3.0 Tonnes of CO2 and by extension, one Ha of gliricidia can sequestrate 146.8 Tonnes of CO2. 20 trees having average of 25 branches can sustain yam staking in a one hectare farmland. The report concluded that gliricidia has the potential to resolve the perennial cooking energy and environmental protection management conflict in the rural Sub-tropical Africa. It is capable of alleviating the stress associated with fuel wood sourcing and the poverty level among the rural dwellers of Africa particularly women and children.
