La ville hors de portée ? Marche à pied, accès aux services et ségrégation spatiale en Afrique subsaharienne

Is the City beyond Reach? Walking, Access to Services and Spatial Segregation in Sub-Saharan Africa. - The aim of this article is to illustrate the links between daily travel and spatial segregation in sub-Saharan Africa cities. In a context of rapid demographic growth, unplanned urban sprawl and increasing poverty of the public sector and the population, in Dar Es Salaam and Dakar, like in other large African cities, trips between distant districts are problematic. The case studies highlight differential access to the urban space between the "confirmed pedestrians" and the users of motorised means of transport, and between the residents from the well-off planned and accessible districts and those from the poor unplanned and inaccessible ones. Deficiencies in the supply of basic facilities and in the accessibility to the neighbourhoods reinforce the negative impact of low incomes on daily travel, and encourage the confinement of populations in their neighbourhood with the risk of increasing urban poverty and segregation.
