This paper explores how informality in the urban Global South can be reframed as a mode of systemic emergence—an adaptive response to institutional neglect, economic necessity, and planning rigidity. Drawing on complexity theory and the concept of cities as dissipative structures, we argue that informal settlements are not urban failures but dynamic systems of improvisation, resilience, and distributed intelligence.
Using case studies from Cape Town, South Africa, we demonstrate how digital twin technologies—integrating high-frequency satellite imagery, LiDAR, and AI-enabled change detection—can support bottom-up governance and ethical urban transformation. These technologies enable the identification of unregulated development and infrastructure gaps, which are then addressed through participatory mechanisms such as citizen service loops. These loops facilitate two-way dialogue between citizens and public servants, initiating valuation, compliance, and support processes that are inclusive rather than punitive.
The paper introduces a triangulated framework combining:
Key findings include improved service delivery metrics, increased throughput, and enhanced citizen engagement. Informality is shown to be a site of civic innovation and ethical improvisation, where adaptive governance emerges not through control, but through relational responsiveness.
This work contributes to WSBE26 themes by offering a systems-based model for inclusive urban transformation, aligning with and extending the Sustainable Development Goals through a post-2030 lens of complexity, ethics, and co-produced sustainability.
