The SYMBIOTIC CITIES NETWORK website is no longer being updated.

The team that created this site is now producing the


Website and Podcast



The Twenty First-Century Imperative Podcast series will explore the approaches and insights of scientists, planners, designers, engineers,politicians, business entrepreneurs, and other successful change-makers, who are finding smart, effective ways to meet the three critical challenges of the Twenty-First Century Imperative:

How will we continue to live on our planet without destroying our biosphere?

How will we repair and regenerate the environmental damage we have already caused?

How will we adapt to the escalating impacts of climate change?

Each episode will feature an interview with an individual who we think you will find not only inspiring, but also very relevant to helping you answer the question: “what can I do to address the Twenty-First Century Imperative?"

If we are to shift from a parasitic to a symbiotic city paradigm, then we will have to find economic strategies that recognize the real value of ecosystem services, as well as the econoimc costs of carbon. We have therefore invited Justin Ritchie , a founder and blogger at the Extraenviromentalist...
