Abstract
Several studies on the disappearance and monitoring of natural resource dynamics on a global scale show a general trend towards the disappearance of natural areas. Protected areas are not immune to this scourge. Thus, this study attempts to analyze the management of protected areas in Côte d’ Ivoire through the Kani-red Bandama classified forest. Overall, the study aims to assess the impact of human practices on the resources of this classified forest. As activities, the aim is to characterize the dynamics of land use in the classified forest and to determine the factors of these dynamics. The study is based on satellite images (Landsat 5 TM, Landsat 7 ETM+ and Landsat 8 OLI/TIRS) from 1986, 2001 and 2016, cartographic and socio-demographic data, and field observations. The preferred tools for data processing and analysis are remote sensing and GIS. The results show that natural areas under the effect of human actions are undergoing very advanced degradation. In 15 years, natural areas have given way to agricultural areas which have increased from 1% to more than 30% with an intensification of cashew nut cultivation resulting in the multiplication of cashew nut orchards. The classified forest of Kani red Bandama is under the influence of human activities reflected by the infiltration of agricultural settlers and breeders whose opposing uses of natural resources lead to conflicts.
Highlights
The question of the disappearance and degradation of the plant cover of protected areas occupies a central place in the field of research in Côte d'Ivoire
A spatial dynamic of land use marked by the gradual disappearance of natural spaces from 1986 to 2016 The land use maps (Figure 2) and the various statistics (Table 1) make it possible to highlight the spatio-temporal dynamics of socio-ecological surfaces
With regard to the analysis of land use maps of the classified forest of Kani Bandama rouge (East) from 1986 to 2001, it appears that the distribution of land cover types was marked in 1986 by a dominance of wooded / fallow savannah and dense dry forests which respectively represented 51.7% and 30.3% of the area with a slight presence everywhere in the eastern part of the Red Kani Bandama Classified Forest
Summary
The question of the disappearance and degradation of the plant cover of protected areas occupies a central place in the field of research in Côte d'Ivoire. The rare forests still persisting in Côte d'Ivoire are found in classified forests, nature reserves and protected areas. These protected areas are influenced by the actions of the riparian populations which each year lead to the disappearance of several thousand hectares of natural areas. In the current perspective of sustainable development and climate change adaptation policies, it is essential to identify and assess the parameters underlying the disappearance of plant cover in order to understand and control future changes, in particular for societal issues on a regional (heritage and economic value) or global scale (carbon stock and emission, biodiversity)
