The 'smart city' is often promoted as a technology-driven solution to complex urban issues. While commentators are increasingly critical of techno-optimistic narratives, the political imagination is dominated by claims that technical solutions can be uniformly applied to intractable problems. This book provides a much-needed alternative view, exploring how 'home-grown' digital disruption, driven and initiated by local actors, upends the mainstream corporate narrative. Drawing on original research conducted in a range of urban African settings, Odendaal shows how these initiatives can lead to meaningful change. This is a valuable resource for scholars working in the intersection of science and technology studies, urban and economic geography and sociology.
