This presentation examines the scientific background and practical possibilities of a spatial planning tool, which provides an adaptive urban framework for the fast growth of sub- Saharan cities. It builds upon an indicator-based sustainability assessment of the area to provide a numeric basis for the generated planning suggestions. The proposed tool acts as a framework, in which the city can develop and grow, while it can be used by planning facilities and developers to determine particular challenges, counteract by suggesting various patterns, and continuously improve itself by extending the data-basis as well as adopting new planning regulations.
