What is ‘green’ infrastructure? What can it do for my city? Why am I definitely way more excited to learn about it than I am more traditional forms of infrastructure? Stephen Elser and Jason Sauer answer all of these questions in this episode, and focus on green infrastructure in the form of wetlands in the city of Valdivia, Chile. They talk to local sustainability consortium leader Cristóbal Lamarca of Activa Valdivia and local wetlands researcher Ignacio Rodríguez of the Centro de Humedales Río Cruces (translated: the Río Cruces Center of Wetlands) about how the wetlands imbue Valdivia with a unique urban character, increase the city’s biodiversity, provide recreational space, and are a form of infrastructure that people rally around.
