At last year’s conference, the team from Tecnológico de Monterrey’s Center for the Future of Cities presented a yearlong effort to pioneer scenario planning in the metropolitan region of Monterrey, Mexico. The initiative combined integrated quantitative modeling and a broad participatory process to identify strategies addressing sprawl, inequality, and fragmented governance. With guidance from the Consortium for Scenario Planning, the project has since adapted scenario planning for this context of high uncertainty, political fragmentation, and weak planning culture. This year, we return to share results, impacts, and lessons from applying this methodology in Mexico’s industrial hub to reshape metropolitan planning.
