A Walk Along the Bièvre River
Carmen Bouyer,  Paris

Since 1912 in Paris, the river Bièvre, once the city’s second-largest river, has disappeared from our landscape. It used to cross the whole left bank from south to north, flowing through the 13th and 5th arrondissements before reaching the Seine between “Le Jardin des Plantes”, our historical botanical garden, and the Austerlitz train station. Today, this 36 km long river...


Nature in Cities in a Post-Covid-19 World: Don’t Blame Urban Density in a Pandemic
Will Allen,  Chapel Hill

As a city and regional planner by training, I have been alarmed at the tendency to blame urban density (defined as people per square mile) as a primary culprit for New York City’s relatively severe initial COVID-19 outbreak. An epidemiologist from Stanford, a professor of infectious diseases at the University of California, and a professor of computational medicine from UCLA...

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.

Family Tree
Andreas Weber, Berlin

Linden In early summer, after the crest of the first wave of the pandemics had broken and kids resumed to go to school and street cafés had opened again, I spent days alone writing on the balcony of a flat in a somewhat sketchy Berlin neighbourhood. Down in the street, two storeys below, groups of young guys drove their BMWs...

To Live in Companionship with Trees, Plants, Rivers, and Mountains
Martine Murray, Melbourne

We are gardening. Feeding our trees. We decide to cut the deadwood off the Fejoa tree. Afterwards it’s considerably squat and oddly shaped, but we agree it looks better. Or it feels better. Or it seems to us that it, the tree, feels better. It has just been liberated of its dead ends. Does it feel lighter and renewed like...

Gifting a White Elephant, In the Form of Green Infrastructure
Amanda Phillips de Lucas, Baltimore

White Elephant: 2. figurative. A burdensome or costly objective, enterprise, or possession, esp. one that appears magnificent; a financial liability. With reference to the story that the kings of Siam (now Thailand) would make a present of a white elephant to courtiers who had displeased them, in order to ruin the recipient by the cost of its maintenance.[i] I. Often when...

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...

Lakes as Urban Classrooms | Reflections on the case of Rachenahalli Lake, Bangalore (2015-2018)
Sumetee Gajjar,  Bangalore

Civic engagement by the Jaimitra trust, and various civic organisations involved in conserving Rachenahalli Lake, was to create a space expected to help alleviate the stresses of living in an urban jungle, and break away from the infamous legacy tied to the images of highly polluted, frothing and aflame lakes of Bangalore.This article argues that using lakes as classrooms can...
