Des Fitzgerald tracks the relationship between the modern city and its green environs. Drawing together psychological research with urban history and literature it asks: what would change, psychologically, socially, emotionally, if we covered the concrete and brickwork of our towns and cities with vines, plants and vertical gardens? A city is not a park but should it be?
Des Fitzgerald is a sociologist at Cardiff University who is researching health, illness and city living. The Essay was recorded at the Free Thinking Festival with an audience at Sage Gateshead.
New Generation Thinkers is a scheme run by BBC Radio 3 and the Arts and Humanities Research Council to select 10 academics each year who can turn their research into radio.
