Attention! Travaux en cours: L'extension des réseaux de services essentiels dans les quartiers irréguliers de Delhi et Lima

Abstract : The extension of electricity, water and sanitation networks in developing cities seems to be a priori complicated by the lack or the deficiencies of urban planning. The modalities of infrastructure deployment into the irregular settlements of Delhi and Lima are here analysed as sociotechnical mechanisms, indicative of the dynamics of the urban fabric. Indeed, on a daily basis, utility firms do install pipes and poles in unplanned settlements. Some technical, social and institutional innovations make the extension of networks possible; the lack of urban planning is therefore not an obstacle to service extension. Nonetheless, this process is not optimal: the conduct of public works is disordered, unpredictability hampers the elaboration of strategies and political injunctions can be contradictory. Such coordination deficits generate uncertainties which are more difficult to overcome for utility firms. There are nevertheless some promising leads for intervention in unplanned settlements: alternative devices for servicing exist that can be promoted; some informal plans and data satisfy the needs for knowledge on the city and would be well worth valuing; and the design and the preservation of the road layout appear to be decisive to allow a coherent, progressive and sustainable urban consolidation process. The analysis of network extension helps to identify key instruments for public action in developing cities, and thus offers new perspectives for urban planning to develop the existing city as well as to strategically prepare for the urbanisation yet to come.
