Today’s post celebrates some of the highlights from TNOC writing in 2018.

When I started my career in land and water conservation almost 25 years ago, cities and nature were usually seen as two separate things. Many strategic conservation planning efforts focused on finding the best places to protect nature from people. But as we have learned from The Nature of Cities and...

(This is a recasting of an essay of the same title recently published in the limited circulation Ecocity World newsletter) “You say you want a revolution Well, you know We all want to change the world You tell me that it’s evolution Well, you know We all want to change...

From early on as a family, we considered ourselves to be fairly knowledgeable about environmental issues, such as plastic pollution, deforestation, and global warming from all we’d learnt through the media.

When we consider planning for green infrastructure, we typically think forward to what kind of city we might imagine for the future. Far less frequently do we consider the history of the city and how past generations have shaped the green spaces and the activities and meanings related to them....

Cities that plan for biodiversity recognize the potential of healthy ecosystems to mitigate urban problems and enhance quality of life but, due to limited capacity, can struggle with developing and managing their biodiversity strategies.

Consequently, many cities have developed climate change adaptation plans that outline projected climate change impacts...

As readers of the Nature of Cities are no doubt aware, we are living in what could rightly be called the urban century, with 2.4 billion more people forecast to live in cities by 2050. In a recent essay in Sustainable Earth, my coauthors, Tim Beatley, Thomas Elmqvist and I...

The image of a child triumphantly brandishing a dead rat on national TV news in New Zealand, trapped in her backyard as part of a community’s bid to try to bring native birds and lizards back into her neighbourhood, reminded me of the extent to which local people in New...

 Jerusalem has been described as “golden” by many poets and writers, inspired not only by the golden domes of holy buildings in the city, but also by the special quality of illumination created when the evening sun is reflected from the famous Jerusalem stone which characterizes most buildings in the...
