Urban Arena is a podcast about creating just and sustainable cities. This month Kate talks with Florian Strenge - an urbanist fascinated by spaces, people and processes.Our urban arena podcast correspondent this month is Sophia Silverton. Would you like to follow in her footsteps? If so, please answer the question ‘What is a sustainable and just city?’ in a maximum of 3 minutes. Record it on your phone or recording device and send it over. It’s up to you what you put in your message, but we encourage you to think about urban sustainability and justice together.
