Implication of institutional informality in the historical urban evolution of Morocco: Case studies of Fes and Oujda

This paper is concerned with the role of informality in the spatial and institutional development of post-colonial cities. The study uses a historical institutionalist approach to trace the historical evolution of Morocco's Fes and Oujda as two former French colonies. It analyzes the historical urban growth of both cities through archival research, policy analysis, and complements its findings with semi-structured interviews. This study explores the different interactions between formal policies and the informal spatial and institutional urban practices, and discusses the processes of incremental institutional change that informal institutions introduce and sustain without disrupting the status-quo. This paper argues that in post-colonial contexts, informality prevails over formality as a stronger feedback mechanism to path dependence. Finally, the paper makes the case for the importance of mapping informal practices within and in relation to formal planning institutional structures for more comprehensive understandings of the role and the impact of spatial planning as a practice. •Urban informality guides urban development in Morocco.•Institutional informality is very visible as a mode of planning governance in Morocco.•Formalized institutional actors often engage in informal planning practices.•Conceptualizing the link between formality and informality can inform post-colonial spatial planning.
