About the Festival

TNOC Festival pushes boundaries to radically imagine our cities for the future. A virtual festival that spans 5 days with programming across all regional time zones and provided in multiple languages. TNOC Festival offers us the ability to truly connect local place and ideas on a global scale for a much broader perspective and participation than any one physical meeting in any one city could ever have achieved. The TNOC festival will take place from 22-26 February 2021.

Registration is open! Session and plenary announcements will begin soon.

The TNOC Festival is a production of The Nature of Cities.

Why Attend the Festival?

Join a diverse international community of urban thinkers to reimagine our cities today, to build the cities of tomorrow. Listen to inspiring keynotes and participate in plenary dialogues. Share the stage and speak about your work in our microtalks. Take up a field trip and visit Mumbai in the morning and be back in Paris by nightfall. Join an international community at a time that works for you, and in a language, you are comfortable speaking.

Now is a critical moment to build transdisciplinary engagement across ways of knowing and modes of action. Join us for a week of focused small-group workshops, collaboration, and dialogue.

  • TNOC Festival keeps the barriers to participation low, with our “follow the sun” programming in all time zones, in multiple languages, and low registration prices.
  • A transdisciplinary event, mixing scientists, architects, planners, artists, activists, practitioners, landscape architects, policy makers, business and social entrepreneurs, indigenous leaders into joined conversations.
  • The festival theme “Better cities for nature and all people” explores and celebrates the environmental justice aspects of green city building.
  • Five days of virtual events and conversation about the nature of cities. How do we achieve cities that are better for nature and all people? Join us to build cities that are more resilient, sustainable, livable, and just for everyone.
  • It will be fun, innovative, interactive, and productive!

Many Voices
in Many Languages

Language is a common barrier to participation at international events. Most international events are hosted only in English. TNOC Festival strives to provide content in various major languages around the world. English is the common language of the festival—the “official” language—but TNOC Festival facilitates and encourages crowdsourced sessions in various major languages. Host a session in a language you and your participants are comfortable speaking.

Radically Imaginative Programming

TNOC Festival programming is transdisciplinary and innovative. With multiple session types, the program is designed to push the boundaries of collaborative engagement by mixing the arts, sciences, and urban practice fields, and performance to draw urban thought leaders and change makers together to build better cities.

Can you propose a session?
Yes! Many session types are proposed and led by participants, particularly seed session, field trips, and city working groups. The session proposal portal is open. We’ll start reviewing proposal on 10 January, but the portal will be open to 30 January. You can propose sessions in any language.

Session Types:


Small interactive workshops that explore an idea or project, or direction actions in cities.


Short talks and conversation among 3-4 thought-leaders in various disciplines. Keynotes from diverse points of view.


Gather to watch a live-narrated video of an actual walk. Watch the video with the trip leader and discuss what you see. The next best thing to being there.


Attend a performance, listen to a reading, participate in collaborative art to build creative human-nature connections.


Small groups work together over the festival week to take action in their city. Map your actions on our global map to be part of lasting change. This is a specific application of a seed session.

Working Groups

Create a meeting withing a meeting, with your organization building an idea hive, or cluster of seed sessions within TNOC Festival.


Contributed very short talks with Q&A, designed to engage and exchange.


Small groups meet for open conversation in various formats. The conversation goes where it will.

What is a Seed Session?
Seed Sessions are workshops on ideas of all kinds, conversations among diverse points of view united by a green perspective. All of these are planned as small(ish) group workshops: after brief scene-setting presentations, each moves to discussion in various formats to explore the ideas and potentials. City groups and Working Groups are types of seed sessions, organized by geography or focus. Seed Sessions are mostly proposed and led by Festival participants—the submission portal is open.

What is an Online Field Trip?
A field trip leader will walk the route of the trip, filming with no narration. At the appointed program time of the trip, the leader plays their video to the participants and narrates the trip live, pausing for questions or discussion. It’s just like a live trip, only the participants are not walking the route. But hey, you can take a trip in Mumbai in the morning, Cairo in the afternoon, Bogotá in the evening. Field Trips are entirely proposed and led by Festival participants—the submission portal is open.

What are Plenary Keynotes and Dialogues?
Plenaries will be large group sessions, typically with three elements: (1) a keynote speech; (2) a “dialogue” in which 3 diverse urban practitioners gather around an idea or challenge, give very short talks, then engage in a conversation; and (3) artistic interludes, such short readings or performance. There will be 4 plenaries every day of the festival , one every six hours: 3am EST, 9am EST, 3pm EST, and 9pm EST, so there will be plenaries convenient to all our global participants.

What are MICROTALKS? Microtalks are pre-recorded contributed papers, organized by themes, but mixing disciplines. Talks are fast! 2 minutes each, and posted as searchable mosaics so participants and browse and explore. The submission portal is open.

Exhibitor Booths? Sponsors of the Festival have “booths”, which include dedicated Zoom Rooms, to program their own events.
