This year has seen our cities coming under pressure as they struggled to withstand the impact of the coronavirus. City centres were deserted as shops shut and people stayed away. But in some city streets there was a new community spirit as people faced the pandemic together and supported neighbours they'd never met before. In this programme, Tamasin Ford investigates what the future could be for our cities, and asks how they need to change if they are to survive, and even flourish. We hear from architect Siri Zanelli; the mayor of Bristol in the south-west of England, Marvin Rees; transport planner Susan Claris; Singapore-based Lauren Sorkin, the head of the Resilient Cities network; Liu Qian of Greenpeace in Beijing, and Rosamund Kissi-Debrah who has been a campaigner for better air quality since the death of her daughter from asthma in 2013.
