Step off the street in Suzhou through a small door and you leave behind the bustling cacophony of a modern Chinese city to enter a different world of tranquility and calm, where natural features create a sense of being surrounded by nature in a tiny oasis that is a scholar’s...

Long-term sustainability necessitates an inherent and essential capacity for resilience—the ability to recover from disturbance, to accommodate change, and to function in a state of health. In this sense, sustainability typically means the dynamic balance between social-cultural, economic, and ecological domains of human behavior necessary for humankind’s long-term surviving and...

Cities pledge to reduce emissions and fight climate change—but do these commitments measure up? The transport sector makes up nearly one-third of urban emissions, a factor influenced by distances traveled and modes of travel. Most cities focus on policies to reduce emissions from modes of travel, such as encouraging residents...

“Thailand is what you make it.” That’s what an ex-pat Westerner who relocated here a few years ago told us when we were strolling through Nakhon Sawan, a busy city in the country’s central/lower north region. This seems true in many regards, or at least from the on-the-ground impressions we...

Inequality is on the rise! Recent statistics published by Oxfam on the economy of the 1 percent show that the richest 62 billionaires own as much wealth as the poorer half of the world’s population. The report goes on to show that the wealth of the poorest half of the...

For many developers and city planners, it takes time and money to plan around trees and small forest fragments. Often, the message from conservationists is that we want to avoid fragmentation and to conserve large forested areas. While this goal is important, the message tends to negate any thoughts by...

According to the United Nations, the second biggest problem for humanity after global warming is disorganized urbanization—urbanization without planning and integration of natural environments. Since 2008, for the first time in history, the majority of people live in urban areas, and this pattern is expected to keep increasing in the...

I have written in previous articles (here and here) that Kampala’s urban landscape has been largely fragmented, just like the landscapes of many other cities. In fact, this is the common character of urban development. But it isn’t the only way. In this article, I illustrate the urban risks that...

Also available at iTunes. Story notes: Federal regulations make clean drinking something close to a guaranteed right for residents of cities in the United States, but not all urban water systems are created equal. Last year, independent scientists and grassroots activists discovered a widespread problem with lead levels in the water pouring...

Increasingly, cities are becoming risky and vulnerable places to live in because of climate change; it is vital to integrate natural defences with gray, or built, infrastructure for sustaining cities. The past decade, from 2005–2015, has shown us what happens when we ignore the vital signs of urban ecosystems, which...

Also available at iTunes. Story notes: I am Jenn Baljko, and my partner Lluís and I started walking from Bangkok, Thailand, back home to Barcelona, Catalonia. Along the 12,000km journey, we’ll explore the idea of just and green cities, occasionally posting our perspectives here on The Nature of Cities—photos, podcasts, and essays on what we...

Rachenahalli is one of the few living lakes of Bangalore, in the north of the city. It is connected to water bodies upstream and downstream, particularly Jakkur Lake in the northeast. Both of these lakes have been rejuvenated, at substantial cost, by the Bangalore Development Authority over the last decade....

I have just returned from an exhilarating week spent in a workshop with a collection of UrBioNet members. UrBioNet is a network of researchers, practitioners, and students with an interest in urban ecology and biodiversity. It is broad in its remit: while it offers opportunities for discussion and sharing, it...

We’ve seen a surge in new open space design initiatives here in New York City in the past decade, with projects as big and bureaucratically complex as the 2,200-acre Fresh Kills Park on Staten Island and as small and locally focused as the Bedford-Stuyvensant Community Garden in Brooklyn. Many of...

Edward Lorenz’s application of chaos theory to weather forecasting is better known to the general public as “the butterfly effect”, thanks to his conference presentation, “Does the flap of a butterfly’s wings in Brazil set off a tornado in Texas?” Lorenz’s law explains to us that there are unknown and...

A frequent refrain in conservation is that we must prioritize. A cottage industry of conservation biologists, among whom I count myself, has risen to plan conservation and set priorities. And in nearly all of the hundreds or thousands of pages of conservation prioritizations that have already been published, nearly always...
