ABSTRACT

Introduction: The issue of waste, in the context of environmental preservation, is a real problem in sub-Saharan Africa. Poor waste

management leads to soil, water and air pollution and is harmful to human and animal health. Background: Solid waste

management is one of the main challenges faced by Ivorian cities, including Grand-Bassam. Objectives: Thus, the objective of this

study is to use GIS to analyze the spatial distribution of solid waste deposits in Grand-Bassam. Methods: The data collection

operations took place between August 2021 and April 2022 and consisted of criss-crossing the town of Grand-Bassam in order to

identify and locate formal and informal dumpsites. The mathematical dimensions including length, width and height or radius of the

dumpsites were determined using a ten (10) meter tape measures. The data was imported into QGIS version 2.18 for the production

of thematic maps. The characterization of landfill sites is assessed in terms of elevation, hydrography, pedology, geology, fracturing

and land use. Results: The geographical survey identified 105 waste disposal sites, of which 87 were informal and 18 were formal

disposal sites, representing 82.86% and 17.14% respectively. The results of the mapping indicate that 56.32% of the illegal

dumpsites are located in the altitudes between 0 m and 7 m. 31.03% and 33.33% of the illegal dumpsites are located on the

hydrographic and fracturing networks of the city respectively. The analysis of waste sites in relation to land use shows that these

sites are mainly (81.90%) located between the agglomerations. In addition, the town of Grand-Bassam is based on a ferralic aerosol

type soil with a coastal sediment type geology. Conclusions: In view of these characteristics and their distribution, these dumpsites

cause nuisances both to the environment and to humans. The cartographic information resulting from the present study serves as a

reference for the elimination of all illegal dumps in the town of Grand-Bassam.
