Michele Acuto, Pro-Vice Chancellor & Vice President and Professor of Urban Resilience at the University of Bristol, joins The Century of Cities to challenge us to rethink cities as more than just clusters of buildings and infrastructure. He reveals how urban centers wield diplomatic power, drive innovation, and tackle challenges from climate change to public health. From the rise of city diplomacy to unexpected partnerships between local governments and global institutions, Michele offers a fascinating look at why the future of international relations might just be urban. How do mayors, urban planners, and everyday citizens influence global agendas? Why should we pay more attention to the power of city networks? And what lessons can we learn from cities that have led the way in resilience and sustainability?
