📺 Welcome to the 29th episode of the Circular Metabolism podcast: "The Role of Urban Infrastructures" with Prof. Sybil Derrible 📺. On today’s episode I wanted to focus on a piece of our cities which I always found a bit boring. It is topic dominated by engineers and which I thought there is nothing new happened since the beginning of the 50s or 70s. However, I later came to realise that if we want to reduce the environmental impact of existing and especially new cities then they are a key component. If you haven’t figured it out already I’m talking about infrastructures. Indeed, urban infrastructures are dictating the way flows circulate with our cities and have immense political and urbanistic implications.
