Our collaborative research focuses on the concept of “corridor.” Corridors are conceptualized as socio-technical systems that integrate territorial transformation and economic growth with efforts to produce sustainable social and ecological environments. A corridor is a unit of analysis organized around linear public transit and its adjacent urban fabric, fostering access and connectivity. The corridor concept is increasingly applied to regional and sustainable development planning in the global south as a government-led top-down planning approach. However, it remains unclear whether and how the corridor can emerge as a critical approach that integrates planned infrastructure with local environmental and social concerns, focused on transformative development through community participation at a metropolitan scale. Our project aims to explore the relationship between infrastructure planning and its transformative effects for sustainability emerging from local communities in cities in the Global South. Using methods of policy document analyses, participatory mapping, geospatial analysis, and key informant interviews, the project aims to situate corridor planning in the wider literature on transformative and sustainable urban development.
