Apport des systèmes d’information géographique (SIG) dans la pré-collecte des déchets ménagers solides dans la Commune d’Agoe-Nyivé 4 au Togo

The problems common to African cities such as galloping demography and uncontrolled urbanization are weakening the systems for managing the waste produced by the populations. Growing urbanization and the unprecedented increase in population present serious problems for sustainable waste management in Agoè-Nyvé, particularly in the commune of Agoè-Nyivé 4. This article analyzes the management of household waste in the commune of Agoè-Nyivé 4 and the contributions of Geographic Information Systems (GIS). This study allowed the application of geomatics to the management of solid household waste. It has made it possible to set up a database with spatial reference on the management of solid waste at the municipal level. These data bring together various information concerning waste pre-collection operators, subscribers to this service, waste collection points present in the sector. The results show that 56.4% of the households questioned throw their waste in nature against 43.6% households which subscribe to SMEs. The research method adopted is based on documentary research, direct observation and field surveys. Data processing was carried out using Arc Gis 10.8, SPSS, Microsoft Excel and Word software. A total of 119 people were interviewed.
