RESEARCH PRODUCT

Comprehending city and its production in Africa through a systemic approach : example of the city of Diamniadio, Dakar

subject

description

For a long time, the analysis of the production of the city in Africa was based on an exogenous perception according to urban models theorized and experimented with in the Occidental countries, then diffused and applied through different mechanisms in the South, bearing witness to historical relations - through the making of the colonial city - and present relations - in the context of the making of new towns. After independence, researchers looked at the redefinition of the city in Africa with its complexity and plurality according to geographical and historical trajectories, proposing new urban theories that were more nuanced and linked to local and contextual realities. Therefore, following a monograph in Diamniadio– the field of study – the main challenge of this thesis is to revisit the fundamentals of the systemic approach, focusing on the sub-system of actors, representations, places at issue and at work, in the urban space with specific temporalities, to demonstrate that there is a rather organic, spontaneous concrete city in a short time, which comes from experiences, from the hybrid articulation of formal and informal practices, from the knowledge and know-how of adiversity of actors - mainly the populations - at the same time as the new city planned and programmed in the long term.
