Identification of illegal dumping and community views in informal settlements, Cape Town: South Africa

Abstract

Municipalities face the greatest difficulty in implementing an efficient and effective waste collection system, especially in informal settlements with limited spatial planning. Illegal dumping is exacerbated by the proliferation of informal settlements and the lack of adequate waste management services provided by municipalities. A geographic information system (GIS) provides decision makers with a framework for analyzing and simulating a wide variety of spatial problems, including waste management issues. The purpose of this study is to map areas susceptible to illegal dumping and to determine why the community dumps there. The data were collected qualitatively via a questionnaire using a purposeful sampling technique, and SPSS 28.0 was used to analyze the data. The accessibility of streets and the availability of vacant land affected the location and concentration of illegal dumping in the test area. The lands within a buffer zone of 250 to 500 m of populated areas are the most vulnerable. The majority of residents have individual garbage receptacles, while a minority of 43.18% do not. A total of 52 dumpsites were identified inside the red zone of the model, suggesting a strong likelihood of illegal dumping activities. Hence, the community continues to have difficulties in effectively managing garbage disposal, compelling them to resort to alternative methods of waste disposal.
