Re-appropriating the Neighbourhood and Re-positioning of Urban Actors in Post-2011 Egypt One of the many social and political consequences of the Egyptian revolution seems to be the reinforcement of the role of neighbourhoods in the collective imaginary and urban action. Under Mubarak, the neighbourhoods, though important in the structuring of urbanisation (in Egypt 60% of housing is informal) were not used as a measure for urban policies: local administration was managed by the central state, while the delimitation of districts and quarters in the governorates was done without reference to the actual use of space, and in the ‘new towns’ at the periphery of cities the design of neighbourhoods was left to private developers. It was only after the January

In the last two decades, sustainable urban development considered as one of the prevalent theories and policies has devoted a major portion of urban-planning literature to itself. However, the subject of sustainable development in the scale of residential environments and neighborhoods requires further consideration. This research is an effort towards inspecting sustainable neighborhood development aspects, in the form of a comparison between two neighborhoods in Tehran: Narmak and Rah-Ahan neighborhoods. Regarding the pre-planned design of Narmak, it is anticipated that the principles and criteria of a sustainable neighborhood would be observed in this neighborhood. In contrast, Rah-Ahan neighborhood was mainly constructed to satisfy the problem of housing production. In the comparative approach, the principles and criteria of identity, liveliness, reliance,

« quartiers de gecekondu : espaces imbriqués, usages entrelacés » Requestionnant le dedans et le dehors, s’attachant aux espaces et systèmes de relation, la contribution dessinera et/ou re-dessinera les gradations, les infiltrations, les imbrications, les entrelacements d’espaces et d’usages qui font quartiers des gecekondu à Istanbul. Un double référence à Michel de Certeau (de Certeau, Giard, Mayol, l’invention du quotidien, tome 2, habiter-cuisiner, Paris : Gallimard, 1994), le quartier [privatisation progressive de l’espace public, p. 20] et la culture ordinaire [science pratique du singulier, p. 360], participera à asseoir théoriquement les fondements scientifiques de cette connaissance pratique.

 » Gecekondu neighborhoods: imbricated spaces, interlaced uses » From a research on four districts of the historical peninsula of Istanbul and a work in progress on gecekondu’s areas, I question relationships and spatial transitions, beyond the legal status of public-private. Re-questioning the inside and the outside, focusing on devices and systems of relationship, the presentation will draw and/or re-draw gradations, infiltrations, nestings, the intertwining spaces and uses that make gecekondu neighborhoods. A double reference to Michel de Certeau (de Certeau, Giard, Mayol, l’invention du quotidien, tome 2, habiter-cuisiner, Paris : Gallimard, 1994), the district [gradual privatization of public space, p. 20] and the ordinary culture [practical science of singular, p. 360] participate to found the scientific basis of this knowledge.
