Différence, dispersion et fragmentation sociospatiale : explorations métropolitaines à Brasilia et Curitiba

Abstract : The passage from the 20th to the 21st centuries has accompanied intense socio-spatial transformations, which have questioned the future of city. On one side,processes of individualisation and social segmentation grow and combine or reiterate inequalities. On the other side and in dialectical way, the production of increasingly dispersed urban tissues is confirmed, i.e., they are characterised by territorial discontinuity and alternating densities from centre to periphery. In this context, urbanisation becomes globally diffused, affects all spaces and articulates different scales in order to produce the urban beyond the cities. In Brazil, especially from the 1970s, the mentioned socio-spatial transformations have occurred and connected to national processes of modernisation. The metropolises of Curitiba and Brasilia developed in this period by different ways. Both of them havebeen marked by inequalities and urban dispersion, but Brasilia experienced itoverwhelmingly. Two aims guided then the discussion proposed in this Ph.D. dissertation: to examine connection between urban dispersion and socio-spatialfragmentation; and to explain how these processes take place in Brasilia and Curitiba. The comparative research has concerned studies and researches about bothcities, but also has counted on a direct way, i.e., through observations, visits togated communities and to cities in the metropolitan agglomerations’ peripheries;some inhabitants were also interviewed. Therefore, the analytical framework of thedissertation helps to understand that there is, in Curitiba and especially in Brasilia, a fragmentary logics that promotes the dissolution of morphologic unit. That happens through the dispersion of urban tissues, social segmentation and reproduction of inequalities, and this is a limit to the right to city as being a right to difference. A necessary reflection about the notion of spatial justice appears then as an appropriate means to seek for overcoming inequalities.
