Côte d’Ivoire, like most African countries, is suffering the full force of the phenomenon of urban sprawl, which in its manifestation causes many environmental problems. In Bingerville, the gradual disappearance of plant resources in favor of ever-increasing urbanization and the problems posed by the cohabitation of man and nature raise questions.
The objective of this work is to analyze the environmental changes linked to urban dynamics in the commune of Bingerville using remote sensing and GIS and to model changes in land use in order to assess the impact of urban sprawl on the plant resources of Bingerville by 2040.
The methodological approach focused first on the processing of multispectral and multidate Landsat images: 1989 ETM, 1999 ETM, 2008 ETM+, 2016 and 2020 OLI TIRS for the analysis of the spatio-temporal dynamics of land cover and a modeling of land cover in 2040 using the CA_Markov model.
From 1989 to 2020, the area of urban stain has increased from 8% to 39%, the vegetation registers during the same period a regression of its area by -3.06%.
The results of the modeling of land use changes by 2040 confirm the trends illustrated by the classification results, the «built-up» class will be the most important land use unit with 49.49%, while vegetation will represent only 10.69% of the total area of the city.
The agglomeration of the urban municipality of Bingerville is a perfect illustration of the constraint that urban dynamics exerts on the vegetation cover.
