Book excerpt: Available Open Access under CC-BY-NC licence. Reporting on the innovative, transdisciplinary research on sustainable urbanisation undertaken by Mistra Urban Futures, a highly influential research centre based in Sweden (2010-19), this book builds on the Policy Press title Rethinking Sustainable Cities to make a significant contribution to evolving theory about comparative urban research. Highlighting important methodological experiences from across a variety of diverse contexts in Africa and Europe, this book surveys key experiences and summarises lessons learned from the Mistra Urban Futures' global research platforms. It demonstrates best practice for developing and deploying different forms of transdisciplinary co-production, covering topics including neighbourhood transformation and housing justice, sustainable urban and transport development, urban food security and cultural heritage.
