In order to allow citizens to engage with, and work collaboratively toward, (more) sustainable urban futures, we need awareness of the infrastructures that co-shape our private and public lives, their interrelations, and one’s own participatory position within these networks. To enable this ‘infrastructural thinking’ and the co-creative processes around it, this project develops a transdisciplinary toolkit for creative urban methods. As a seed money project for the Tranforming Infrastructures for Sustainable Cities hub, we aim to create a robust methodology for research into (futures for) sustainable urban infrastructures through a productive exchange between the social sciences, geosciences and the humanities.
