Impact of Vegetation Over Exploitation in Relation to Carbon Stock of Savannah Trees in Minawao, Mayo-Tsanaga Division (Far-North Cameroon)

Research Article

Abstract

In order to resolve the various environmental problems such as global warming that the world is faced with today, international organizations have been deployed for decades to provide valuable solutions. In the same vein, this study could highlight its contribution in this context. Since refugees and displaced people have occupied Minawao, the loss of biodiversity has increased, many species are threatened with extinction, yet each of the plant species is a carbon stock. In order to promote phytodiversity, the evaluation of the amount of carbon stored by savannah trees in the Minawao area would be a development issue. Located in Mayo-Tsanaga Division, Far-North Cameroon precisely in the canton of Gawar, Minawao occupies the granite-gneissic base of Mount-Mandara. A floristic inventory in four (3.75 ha/CU) Collecting Units (CU) was made according to the cardinal points in relation to the Minawao camp. To analyze the data, Excel was used to input data and calculate, Stat graphics plus 5.0 was used to compare variable and ENVI 4.5 to realize the map of the study area. On an area of 15 ha, we inventoried 7143 individuals belonging to 59 species, distributed under 42 genera and 30 families. The most represented species are Anogeissus leiocarpus (22.33%), Acacia polyacantha (12.29%) and Balanites aegyptiaca (6.22%). The amount of carbon stored by all CU is on average 166.01 tC/ha, equivalent to 1660.08 $, corresponding to 457328.71 CFAF. CU4 has the highest carbon content (346.07 tC/ha) than other CUs that do not differ significantly (P> 0.05) between them (15.43-175.20 tC/ha). Given the heterogeneity of the various CU, certified by their different values, a dignified development plan would be welcomed.
