Résumé
This paper analyses knowledge in social sciences about the conditions for and the process of institutional change in the urban sanitation sector in the Global South. We conducted a literature review of 148 papers. This review is organised around the six steps of institutional change proposed by Greenwood et al. (2002). Most studies focus on conditions and barriers to change, on the “legitimacy” of social or technological innovations, and the actors promoting change. The change process is rarely analysed from a long-term perspective, nor at the city scale, calling for further research.
