Sustainability Transition in urban rivers: analysis of the drainage regime in the Tamanduateí river basin
The research aims to analyze urban interventions that address drainage and flood mitigation plans, programs, and projects in the Tamanduateí River basin. The focus will be on the municipalities of Santo André and Mauá, selected for their territorial and institutional differences. The history of river and stream management in the region heavily using gray infrastructure, including channelization, valley-bottom road systems, and large reservoirs, suggests the existence of an intervention paradigm. Unfortunately, even the field of urban drainage has shown insufficient results under the current socio-technical regime. The planning process involves social, technical, urban, and ecological factors. Therefore, the methodology includes identifying and analyzing interventions in watercourses in depth. The study examines the stability of the socio-technical regime through the rules, practices and values of actors and institutions, and the institutional transformative capacity to change the reproduction of the status quo of interventions in the rivers and streams of the Tamanduateí basin, towards a desirable transition to sustainability.
