Join us for a discussion with Setha Low on her new book, "Why Public Space Matters," in conversation with Ya-Ting Liu, Matthew Clarke, and Quilian Riano.

This program presents powerful, recent findings about the importance of public space in the creation of a more just city. The discussion will focus on the contributions of public space to democratic practices, health and well-being, sustainability, work in the informal economy, and social justice. The panelists will explore—from the perspectives of a researcher, city leader, non-profit organization, and educator—what these lessons mean for a dramatically changing New York City. With participation from the audience, the conversation will explore why public space matters to New York City.
