Abstract
The study, which covered "study the dynamics of the Minawao vegetation cover and its surroundings (Far North, Cameroon), took place in five villages: Minawao, Gawar, Sabongari, Windé and Zamay. The main objective was to help manage the impacts of populations on the Minawao vegetation cover and its surroundings in order to improve the living conditions of refugees and local populations. In each village, floristic surveys were carried out in 5 plants formations (shrub savannah, forest gallery, tree savannah, field and dwellings). For satellite images, the 14-year interval (2006 to 2020) was retained. Analysis of the data identified 23 species, 21 gender and 14 families over the 120 hectares of study area. The annual rate of regression indicates that the village of Minawao and the river side villages are experiencing more degradation after the settlement of refugees than before, with their respective regression rates of -10.81 ha/year and -8.93 ha/year. The maximum carbon is stored by Acacia albida (11.77 tC/ha) and Tamarindus indica (8.11 t/ha). The total amount of carbon in this area is 32.32 tC/ha.
Highlights
The dynamics of the vegetation cover occur in any plant space in a natural way [1]
The factors of degradation of the vegetation cover are more present in the village of Minawao (73.49±18.89%) and Gawar (65.14±23.56%)
Among the factors influencing the dynamics of the vegetation cover, logging (99.62±0.60%) is the main cause of the degradation of the vegetation cover in Minawao and the other surrounding villages
Summary
The dynamics of the vegetation cover occur in any plant space in a natural way [1] This dynamic phenomenon can become problematic when masses of people settle in a space and enhance the natural resources there [2]. The dry zones of Cameroon in general and the semi-arid region in particular have undergone significant socioeconomic and cultural changes over the past decades, accompanied by rapid transformations of rural landscapes. Despite these different changes, populations, for the most part poor, depend on natural resources for their well-being [5].
