Abstract:
In Benin, municipal solid waste poses a threat not only to the environment, but most importantly to public health and safety (EBA, 2002). The general objective of this research is to inventory the infectious foci and pre-collection structures of DSM in the city of Porto-Novo
In order to achieve the results, several software and data collection tools were used. These are questionnaires, the development of landfill census records and observation grids, Garmin 60 GPS for surveying the geographical coordinates of the dumps and seats of DSM pre-collection structures, cameras digital for taking photos of dumpsites and observations made on the ground of certain phenomena, Arc GIS 10.3: is used for the realization of the thematic maps and the spatial analyzes. The target population is composed of heads of households in the 31 districts selected for the study. The application of Schwartz's formula (1995) made it possible to choose 383 people as the size of the sampling. At the end of the processing of the different data, the following results were obtained. Thus, the inventory of dumps reveals 581 dumps of DSM distributed throughout the territory of the municipality of Porto-Novo. Analysis of landfills and their areas of influence show that 92% of the surface area of the study area is threatened by a hazard, of which 34% is considered to be at high risk.
