A satirical video circulated this past summer announcing Mexico City as the country’s newest and most exciting water park, featuring waterfalls in the metro and an airport runway turned waterway.[1]  I thought they might have included the geyser spouting out of a drain that I saw next to the sign...

Almost exactly two years ago, South America was swept up in a public health crisis that affected hundreds of thousands of women across the continent. In Brazil, more than 2,600 children were born with the microcephaly and other health complications resulting from the viral infection Zika. Brazilians quickly became accustomed...

In the weeks prior to the writing of this article, the city of Bengaluru was reeling under the onslaught of torrential rainfall, the likes of which it had not witnessed in decades. Effects of this downpour were felt in many ways—flash floods in several parts of the city, trees uprooted,...

In most arid regions of the world cities are growing and rivers are running dry. While rapid urbanisation has left little room for creating new public open spaces, could urban riverbeds that remain dry for an extended period of time provide potentials for new types of public parks? Dryland settlements...

Whenever I listen to the song Some Kind of Nature by the Gorillaz & Lou Reed, it makes me think about what kind of nature we are going to end up with in our cities, even though the song isn’t actually about urban nature at all. From my perspective here...

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...

Streets are often the biggest share of publicly-owned land in a city. All too often, they’re conceived and managed only as thoroughfares for motor vehicles. A whole set of standards has...

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!...
