The failure of residual materiel management system on the outskirts of the Ebrie lagoon of Abidjan (Côte d’Ivoire)

Abstract

The management of residual materials in urban area, and particularly on the edge of lagoon bays is considered as one of the most serious environmental problems which are facing cities en developing countries. It is in this context that the present study whose objective is to understand the drivers of the dysfunction of the residual materials management sytem on the outskirts of the Ebrie lagoon in Abidjan. The literature searches, observations, surveys and field studies as well as socioeconomics urveysdrew out the results of the study. These made it possible to understand that the insufficient number of garbage containers (2,8 %) and garbage can (18,6 %), the high number of wild deposits in the districts (57,9 %), the uncontrolled deposits on the edge of lagoon bay (20,7 %) highlight the failures of the residual materials management system in the study areas. Despite the collection service of private actors which benefits 85,1 % of the population and 14,9 % for that benefiting from the services of the town halls, the study has shown that the inadequacy and unequal distribution of garbage containers, their acces conditions as well as the long distances make the service of collections of sporadicwastes and lead certain the wasteprecollectors and households to pour the wastes on the lagoon bay.
