Juliana Montoya and Juan Azcárate, Bogotá (To read this post in English, see here.) Asilvestrando ciudades: Una perspectiva desde la biodiversidad latinoamericana Analizando la idea de asilvestramiento de las ciudades (re-wilding cities) como espacios que permiten la vida de especies de forma natural y espontánea en lugares diferentes a su...

Regular readers of TNOC will be familiar with the biophilia hypothesis, which supposes an innate emotional link between humans and the natural world that positively impacts our psychological wellbeing. In other words, we feel most at home in naturalistic surroundings, as this is where we evolved and have spent the...

Some weeks ago I took part in a seminar in Recife, Brazil, where colleagues of Brazil, Colombia, Chile, and Mexico met. The main queries to be answered were: How each professional from their individual specialities could collaborate to address the New Urban Agenda established by the Habitat III Conference, held...

There is strong interest in the theme of re-naturing cities, since “naturalizing” cities can help address multiple global societal challenges and generate benefits, such as the enhancement of health and well-being, sustainable urbanisation, the provision of ecosystems and their services, and resilience to climate change. But, what are the theories,...

Humans have been living with wildlife since time immemorial. But with the growth of cities, people have become so distant from nature and wildlife that many think there is no native flora and fauna left in urban jungles. This alienation raised such concern in the global community that the United...

Warning: What follows is entirely personal and non-scientific. This is a good thing. I live and work in a global city. Here’s my justification for being here. I work on scaling up greening in cities across Europe. My global city—London—has been a leader in urban greening initiatives for many years....

In previous TNOC posts I wrote about two apparently different topics: urban agriculture and living underground. Let’s combine them now into a new urban object: Farming underground. You may very well think that I am playing smart-aleck here, and that this paper is just a piece of bravura, since farming...

If you took the city of Tokyo and turned it upside down and shook it you would be amazed at the animals that fall out: badgers, wolves, boa constrictors, crocodiles, ostriches, baboons, capybaras, wild boars, leopards, manatees, ruminants, in untold numbers. There is no doubt in my mind that that...

Increasingly, urban nature is viewed not only as a scientific, technological or design issue, but a moral one. The recent TNOC roundtable “Ecosystems for everyone” rested on the assumption that provision of and access to ecosystem services and urban nature is a “moral imperative”. Indeed, Steward Pickett began his contribution...

The impacts associated with city functions, economic, environmental, mobility, extend well beyond their administrative boundaries. But the contemporary and dominant frameworks and systems for managing cities have always determined what activity is allowable, where, and how the infrastructure and any developments pertaining to the function would be developed. Thus, functionality of...

Looking back over 50 years working as an ecologist some things stand out as real success stories. Camley Street Natural Park in London is one of these. On the day that I started work as Senior Ecologist at the Greater London Council (GLC) in 1982 I learnt that the Council...

We walk through Mashhad, Iran, and start giggling like children. “Look how clean everything is! There are trash bins, and parks with good exercise equipment, and wide sidewalks you can actually walk on without being sideswiped by motos, rickshaws, bicycles and cows! Oh, how nice… they painted the park benches!...

Worldwide, cities are grappling with aging infrastructure, shifting populations, and changing weather patterns, necessitating the use and expansion of green space in equitable and creative ways. Many are embracing a transition from the sanitary city—comprised of siloed functions and grey infrastructure—to the sustainable city—comprised of regenerative and distributed systems that...

Broken and disparate urban landscapes are common experience. The multitude of issues and concerns that are causing such conditions are not new; neither are responses of those who are committed to ideas of sustainability. Yet, discussions of the causes and responses have to be repeated many times over, in order...

Combating nature-deficit disorder—the new self-help fad, or something really useful? When I stumbled on Richard Louv’s book Vitamin N (2016 Algoquin Books) my initial reaction was one of shock. Have we really...

To plan resilient cities is a complex task. It involves making decisions that involve the built, social, economic, and environmental development of a territory, including unexpected changes, such as those caused by extreme natural events. The effects of earthquakes, tsunamis, volcanic eruptions and fires, among other disturbances, need to be...

This is a tale of an experience I had in Alachua County, Florida. The challenge? How can we encourage the construction of more natural stormwater ponds, which offer more wildlife habitat and more efficient ways to remove pollutants? We have all seen conventional stormwater ponds—deeply dug ponds, with mowed turfgrass...
