Retrieving the Baby from the Bathwater: Slum Upgrading in Sub-Saharan Africa

Drawing on project experiences over a thirty-year period and academic literature, this paper focuses on the question: what has worked in slum upgrading in Africa? We find that efforts to regularize land titles to confer de jure security of tenure have not been encouraging. By contrast, infrastructure investment efforts have performed better—they have conferred de facto security of tenure and also ameliorated living conditions. Over time project-based learning and microlevel innovations have helped improve upgrading performance. To create broader and sustainable benefits, however, upgrading needs to go to scale. We propose an upgrading strategy with the following elements—a programmatic approach that links slums to citywide systems, is channelled through government, and combines a community-demand and participation approach with supply-side constraints and rules of access.
