A Critical Theory of Urban Planning and Social Reproduction in Post-Colonial Nigerian Cities

Nigerian urban planning practice and its theoretical foundations retain significant colonial-era characteristics that shape the relationship between formal planning systems and the social reproduction needs of the urban majority. This study develops a critical theory of urban planning and social reproduction in post-colonial Nigerian cities, making an original theoretical contribution to planning theory by articulating how planning systems interact with, enable, or frustrate the material conditions through which urban households sustain themselves across generations. Grounded in critical social theory drawing on Harvey, Lefebvre, and post-colonial urban theory, the study employs a multi-year critical ethnography in three Nigerian cities: Ibadan, Kaduna, and Owerri. Data collection includes 150 life-history interviews with urban residents, 45 planning institution interviews, and analysis of planning legislation, spatial plans, and development control records from the colonial era to the present. The dialectical analysis traces how planning instruments including zoning, building standards, and land administration have interacted with housing provision, informal employment regulation, and public space governance in ways that structurally disadvantage lower-class urban residents. Original theoretical contributions include a post-colonial urban planning critique framework and a social reproduction-oriented planning normative theory adapted to Nigerian urban conditions. The study challenges predominant modernist planning theory's applicability to West African contexts and proposes alternative theoretical grounding for a distinctly Nigerian planning theory.
