The Summit is finished, but check back here in the coming weeks and months to find various outputs and next steps.

The Vision

How do we create green cities that are better for both people and nature? Cities that use green spaces and biodiversity to become more resilient, sustainable, healthy, livable, and just? It is a core challenge of our time, around the world.

It is through collaboration that we can make an impact that is greater than any one of us could achieve alone. In this spirit, the TNOC Summit is altogether a new creation. The TNOC Summit is where thought leaders, from communities of practice, policy, and academia come together in a truly transdisciplinary and collaborative event to think, learn, create, and build in interactive sessions.

The principal aim of The Nature of Cities Summit is to spark conversations across ways of knowing and modes of action to build a movement—a new collaborative and transdisciplinary movement for green cities that are just, livable, resilient, healthy, and sustainable.
