Gestion des déchets solides ménagers et ségrégation socio-spatiale dans la ville de Conakry

Abstract : Household wastes have become a crucial problem which worries more and more municipality and population in Conakry. Because the current way of managing of waste is marked by important dysfunctions. The rate of collection which of 70% was in 1997 reached hardly today the 20% whereas the quantity of waste produced keeps on increasing, (600 T in 1997 to more 1500 T in 2015). The inoperative character of the structures of collection and evacuation of household wastes promote the establishment of the uncontrolled wild dumps everywhere in the city. The rubbish not collected, the sewage not channelled, the degraded roadway systems have become the nightmare of the inhabitants. Following this increasing insalubrity, Conakry displays the image of a city taken hostage by “mountains of rubbish”. The latter has become the reflection of a dual socio-spatial configuration with the existence of a kind of “segregation” in the service of pre-collection and waste disposal. At the time when the main axes, the administrative centres, shopping precinct and the rich districts profit from a minimum service of collection, the popular quarters and the poor where however the high densities of populations lead to the production of important quantities of waste are completely ignored. One attends thus through waste management two cities in the same city: a modern city with more or less of collection and the other, forsaken with unhealthy districts. In front of these disparities, the authorities developed and tried out tools and try to find strategies of optimal management. Unfortunately, the tools implemented showed their limits, because they appeared ineffective. Our thesis tries to analyse the reasons of these failures of management in a context of socio-space segregation and to build a prospect for management which takes into account the treatment and valorisation for the improvement of the environmental and medical situation of the country. The data which made it possible to lead to these results come from a document retrieval undertaken in France and Guinea, of a work of geolocation of the sites of household wastes, talks near the institutional and no institutional actors, and investigations near the households of the city.
