The assessment of carbon storage capacity in forests is a key tool for combating climate change and contributing to the mechanism for reducing emissions from deforestation and forest degradation (REDD+). The objective of this study is to assess the carbon sequestration potential of the major land use types (LUT) of the Djoli-kera classified forest. Direct observations on 50 m x 50 m plots, and socio-economic surveys of 126 individuals, identified four major LUTs: agricultural areas, intensive grazing areas, areas frequently subjected to bushfires and savannah with trees. Carbon stocks of dead wood and live wood were calculated, and root carbon stocks were assessed using the root/stem ratio. The method used for estimating carbon stocks is the non-destructive one which uses mathematical equations called allometric equations which incorporate variables of diameters and/or heights. Estimated carbon stocks are 54.8 tC/ha in agricultural areas, 102.04 tC/ha in pasture areas, 108.5 tC/ha in tree savannah and 177.5 tC/ha in bushfire areas. These carbon stocks correspond respectively to the following quantities of atmospheric CO2 sequestered: 201,3 t CO2 eq/ha; 374,4 t CO2 eq/ha; 398,2 t CO2 eq/ha and 651,6 t CO2 eq/ha. The families with the highest values of these stocks are Fabaceae and Combretaceae. In the carbon market, sequestered CO2 is likely to produce an estimated average forest economic value of 862,570 Fcfa/ha. The total economic value of the Djoli-kera classified forest is estimated at FCFA 80,822,809,000. |
