Résumé :

The thesis explores how in incremental cities, built environments and related water and sanitation infrastructures are extensively co-produced and constantly re-configured by successive grafts on the system of pre-existing structures that compose them. This process of transformation is characterized by the interplay of permanence and change, by cycles of coming and going, growth and decay, in which its components are transformed into something different. In this process two forces, engines of transformation emerge. On the one hand, a comprehensive and top-down planning and design approach, which advocates for an urban and infrastructural planning, increasingly dictated by the paradigms of order and control. On the other, an incremental and bottom-up process in which individuals and communities approach the city pragmatically and contribute to its change with small acts of design. The two forces operate simultaneously on the processes of re-configuration of the built environment and water infrastructures at different scales, allowing for processes of hybridisation, accumulation and mutual adjustments. The purpose of this thesis is to surface the dialectics of these processes in the cities of Hanoi and Cochabamba: to show how incremental transformations generate systemic changes in the long term, and finally to show how this process is mediated by the continuous adjustment of existing socio-spatial boundaries that shape practices of wss co-production.
