Many voices. Greener cities. Better cities.



The Value of Green Urban Assets and the True Costs of Development
Martin Westerman,  Seattle

The building boom that’s driving up real estate prices and jamming Seattle with housing and high-rises is also squeezing out and devaluing the city’s green and open spaces. That “progress” presents paradoxes: “Hard assets” provide value temporarily, as they are amortized over their “useful lives”; green, or “soft,” assets are never amortized, and provide value forever. And “progress” has now...


The Shape of Water, the Sight of Air, and Our Emergence from Covid
Lucie Lederhendler,  Montreal

“Absences should not cause us to look elsewhere, but to look closer.” i I have been working on a mind map of emptiness, inspired by an old Wiccan meditation practice of gazing into a bowl of water and trying to see the middle of the water.ii In the middle of a large sheet of newsprint, I encircled the word “emptiness” and...

My Past, Present, and Future: A Review of Ecological Mediations
Malerie Lovejoy, Oxford

The sciences meet the arts in the poetic renderings of Dr. Karan Aggarwala’s 2010 collection, Ecological Mediations(Xlibris). An optometrist by training, Dr. Aggarwala’s poetic view of the world reflects years of science met with a holistic ecological view of the mechanisms of our world. His inspiration draws clearly from personal experiences and stories of his family. He writes his heart...


The Place of Nature in Cities: Taking Inspiration from Singapore
Perrine Hamel, Singapore

What is the place of nature in cities? As the COVID-19 pandemic challenged societal norms, this question took a new turn for professionals and the public alike. Having recently moved to Singapore I’m sharing here a few thoughts as I’m learning how the city-state designs our relationship with nature. Singapore is often praised for its forward-looking approach to greenery planning....

Crisis Reveals the Fault Lines of Gender in Environmentalism—How Do We Value Everyday Environments?
Nathalie Blanc, Paris
Sandra Laugier, Paris
Pascale Molinier, Paris
Anne Querrien, Paris

These are times of crisis. One might even think that the COVID-19 crisis looks like a an alternative expression of crises that are already building, especially ecological ones. Harald Welzer in The Climate Wars shows that the feeling of crisis as well as fear is born in the face of the unpredictability of the times to come. However, it is...

Getting to Know You: The Under-Appreciated Art (Science) of Slow Research and Arts-Led Community Engagement
Paula Vandergert, London
Susie Miller Oduniyi, London

Know the feeling when every project seems to require a huge amount of work in a short amount of time, for very little reward?? This seems to be the way of the world, whether you’re a practitioner, a researcher, or a community activist (or all three). I was prompted to reflect on this when I (guiltily) turned down a request...

Four Recommendations for Greener, Healthier Cities in the Post-Pandemic
Takemi Sugiyama, Melbourne

Manoj Chandrabose, Melbourne
Jonathan Kingsley, Melbourne
Niki Frantzeskaki, Melbourne
Neville Owen, Melbourne

The extensive societal changes brought about by COVID-19 restrictions have given pause for thought on how we can create healthier and more equitable cities as we transition to a new normal. Public health measures to reduce the spread of COVID-19 have meant that opportunities to go out and interact with others have been limited, with many of us spending large...

lowlands—Small-Scale and Nimble Projects that Create Resilient and Just Cities

A research and design framework, lowlands looks at public housing projects in environmentally vulnerable locations—specifically, low-lying lands, often on former marshes. A quick survey of New York City public housing projects demonstrates that this is a...


Defining the Just City Beyond Black and White
Toni Griffin,  New York City

When I think about the just city, it’s always black and white I was born in Chicago the evening before President Lyndon Johnson signed the Civil Rights Act of 1964 into law. Growing up on the south side of Chicago meant that on an average day, I rarely saw or interacted with a person who didn’t look like me. All...


Urban China’s Appetite for Land
Judy Li,  Beijing
Pengfei XIE,  Beijing

Efficient land use for urban development is crucial for limiting urban sprawl, conserving nature around a city, and improving the livability of the city itself. In China, the unprecedented speed of urbanization over the past three decades has unfortunately resulted in widespread inefficient land use, creating problems that only some cities are trying to solve today. China is already home...


Time of the Poppies
Andreas Weber,  Berlin

“Do you seek the highest, the greatest? The plant can teach you to do so. What it is without will of its own, that you should be with intent – that’s the point!” —Friedrich Schiller Some days ago, after giving a lecture in a west German city, I arrived back at my Berlin neighbourhood subway station and walked home. I...
