Use of Multi-Criteria Analysis (MCA) as a means of determining the location of waste management infrastructure and urban cleanliness facilities in Touba Mosque

Abstract

Marked by a very strong demographic growth, rampant urbanization, and a dynamic economy, the city of Touba is also experiencing new consumption patterns (retail sale, fast food, popular use of disposable textiles, etc.), once prevalent in the world's largest cities. These elements are among other decisive and essentially responsible factors for the significant amount of waste produced in this city. This proliferation of waste, which is accompanied by the multiplication of illegal and recurrent dumping sites, justifies on one hand, the need to disseminate waste management infrastructure in this city so as to maximize waste collection activity, on the other hand to bring the population closer to this public service, which is waste collection. Thus, the usage of solutions offered by GIS seems essential to model a justified distribution of these infrastructures.

The aim of this research is to provide an overview of the current spatial distribution of urban cleanliness equipment in Touba and to concretely explore GIS solutions that will enable optimal distribution of these waste management infrastructures through Multi-Criteria Analysis (MCA).

The methodological approach used in this research is quantitative, with the development of a questionnaire using Kobotoolbox to collect information on the urban equipment deployed in the city of Touba Mosque, but also technical, with the explanation of the various processes used to carry out the MCA.

The results of this study have shown that the city of Touba is facing a high production of waste, hence the presence in several locations of waste management infrastructure (IGD). The audit of the dissemination of urban cleanliness equipment shows that it does not rely on justified selection criteria regarding the locations of the sites where the IGDs should be located. This is why the idea of using the MCA method has been proposed, which makes it possible to identify favorable or suitable sites for the implementation of IGDs and urban cleanliness furniture.
