At the end of October, the United Nations has a designated World Cities Day in which they ask the international community to promote discussion and exploration on the topic of the urban environment. For 2019, the theme selected by the UN was Changing the world: innovations and better life for future generations. In this episode of If/When we discuss the future of cities with Professor Michael Keith, co-Director of the Oxford University Programme for the Future of Cities and Brian Burkhard, the Global Technology Leader - Advanced Mobility Systems at Jacobs.
