VOID URBANISM: Unbuilt New Cities and State Formation in the Democratic Republic of Congo

International Journal of Urban and Regional Research, EarlyView.
Abstract Based on an analysis of the planning process behind Kitoko City in the Democratic Republic of Congo—a new city project officially launched in 2019 but never implemented—this article examines the political, social, and spatial effects generated by urban initiatives that remain at the stage of intention. It investigates how such unbuilt projects
