Urban Exchange: Cities on the Frontlines is the podcast series from SmartCitiesWorld and the Resilient Cities Network (R-Cities), delivering frank and open conversations between international city leaders and industry practitioners that share ideas to solve urban challenges. With the world’s cities under pressure to deliver a sustainable future for more than half of the global population – a figure that is consistently trending upwards – the Urban Exchange provides a platform for the people driving urban innovation and change to share their ideas and insights with those that need them most. As cities seek a future that is environmentally, economically, and socially resilient and sustainable, each episode of the podcast plays host to an in-depth conversation between a city leader and a smart city specialist to uncover the initiatives that cities are working on to deliver on these goals.
