Abstract
Environmental conditions change in the Southwest of Cote d’Ivoire has been a major issue in development debates over the last decades. Using remote sensing based on land cover change analysis, climatic data, national statistical data, we analyzed the drivers of environmental change in Southwestern of Cote d’Ivoire. Being part of the perennial crops basin, Southwestern of Cote d’Ivoire has witnessed rapid degradation of environmental conditions caused by the conversion of forest areas to agricultural land during the last 20 - 30 years and by a combination of decline in precipitation, soil degradation, a diversity of policies with little concern for the environment and population pressure. We concluded that while climate variability has influenced environmental change in the area of Sassandra, various types of anthropogenic and State interventions in agriculture appear to have been the main underlying causes of environmental degradation.
Highlights
Côte d’Ivoire is located in the intertropical zone, with about 60% of the population living in rural areas and the largest share of GDP (Gross Domestic Product) coming from natural resources extraction
To understand the impact of environmental degradation on local climate variability we study by Kriging, changing Isohyets by decade with data from thirteen stations (Figure 6)

Summary
Côte d’Ivoire is located in the intertropical zone, with about 60% of the population living in rural areas and the largest share of GDP (Gross Domestic Product) coming from natural resources extraction. The natural vegetation is constituted by important forest cover in south and savanna in the north. The performance of the Ivorian economy is largely based on agriculture which contributes about one third of GDP and employs more than 60% of the population [1]. A significant change in crops production could thereby have a direct impact on the economy. The importance of agriculture in the national socio-economic development is recognized, forests and soils of Côte d’Ivoire remain very assaulted mainly because of cultural practices. Land cover change due to human activities is currently proceeding more quickly in developing countries than in the developed World, and affected strongly the surface temperature [2]
