Gestion Des Matières Résiduelles Et Pollution Lagunaire A Abidjan : Responsabilités, Stratégies Et Perspectives

Abstract

The poor management of household waste is responsible for the deterioration of the living conditions and the natural environment in Abidjan. Focusing on the case example of the pollution process of the Marcory- Treichville lagoon bay, this article identifies those responsible for the problem of insalubrity in Abidjan city and proposes palliative strategies. The probabilistic and judgemental methods were used to determine three sampling sites where GIS and other field investigations were conducted. The results of the field investigations show that paper/cardboard (20%), plastics (40%), wastewater and excreta (80%) and household waste (75%) pollute the Ebrié lagoon despite the good eco-citizen’s conscience of 83.1% of households who pay for the services of private pre-collectors; 9.4% prefering the municipal waste collection services. It follows from this that sustainable management based on the Quebec model of integrated waste management (3RV-E) or the creation of landfill sites will contribute to clean Abidjan city.
