Diepsloot, a township in Johannesburg, South Africa, was used as a case study to explore the perceptions of people in informal settlements towards their role in limiting pollution in their environment. The method followed was qualitative, and primary data were collected through the use of key informants (Ward Councillor and Environmental Health Officer), and three focus groups. Diepsloot is a marginalised residential area located in the Northern perimeter of the City of Johannesburg. The settlement is spatially fragmented, reflects a high residential density and is plagued with high levels of unemployment and poverty. Compounded by poor municipal service delivery, these challenges lead to a range of environmental problems such as overflowing solid waste on the streets, water pollution, and high levels of indoor air pollution. The study found that there were varying levels of commitment to limiting pollution by people in the informal settlement. This (commitment to limiting pollution) was largely dependent on community action through the formation of street committees. In streets where there was community cohesion, street committees were stronger and environmental conditions were better. In contrast, environmental problems were worse where street committees were weak or not operating. Regarding the role of government, the major constraints leading to unresponsive interventions were the limited scale of municipal operation and their poor communication with residents. Suggested corrective measures include recycling, education on pollution and the need for institutional strengthening. Further research aimed at identifying a set of appropriate partnerships and institutions needed for responsive interventions in informal settlements is required.
