| Summary: | This paper is concerned with the impact and implications of gated communities on urban sustainability. This is investigated making use of an overarching methodological framework based on the internationally accepted Driver-Pressure-State-Impact-Response (DPSIR) model, developed by the OECD. Additional to the simple causal flow from drivers to responses are the dynamic relationships between these five aspects. The paper discusses each of these issues and the relationships between them as they pertain to gated communities in South Africa. Gated communities, as complex systems, necessitate the consideration of a multiplicity of feedback loops with internal rates of flow that are determined by non-linear relationships. Only in this way can the full extent of their impact and implications on urban sustainability be assessed.
