The Nature of Cities was launched 10 years ago, in June 2012. I believe it has been a success, with over four million reads and around 1,000 contributors. I believe it has been valuable in framing and propelling dialogue in its promotion of collaboration and transdisciplinarity that are essential to...

Read in English. Retrouver le sens perdu et affirmer l’identité du parc Les parcs sont aujourd’hui une collection éclectique de strates de paysages aménagés et construits issus de multiples époques[1]. Autant pour ceux qui réalisent des parcs que ceux qui les conçoivent, il est à propos de se questionner sur...

What is it? City authorities around the world are looking for policies and tools to facilitate urban greening ― in particular, the process of bringing more soil, vegetation, and water into the built environment through the development planning system. In the UK, authorities are looking at the Urban Greening Factor...

I recently had the great pleasure and privilege of a holiday on a boat in the Maldives. I had never sailed before, and am by no means an ocean-going character (indeed I took a year of swimming lessons in anticipation of this holiday), so the whole experience of being at...

Project study within the framework of the Swiss Biodiversity Strategy Action Plan Increasing building density is putting pressure on green spaces and thus on the living conditions for flora, fauna, and humans. However, the sixth IPPC report and the COVID-19 pandemic clearly show green spaces that enable recreation and the...

Russia’s invasion of Ukraine has exacerbated existing problems in global supply chains of two fundamental commodities, namely energy and food, which in turn are leading to soaring inflation. In response, several countries are abandoning their commitments made at the COP26 conference to reduce carbon emissions and instead going back to...

The Year 2007 marked the arrival of the Urban Millennium when most of the world’s population became urban for the first time in human history (UNDESA, 2009). The proportion is now at least 55% and the global urban population is predicted to increase by 2.5 billion over the next 30...

Spiders are among my favorite urban neighbors. They’re flashy, charismatic, and they’re everywhere. Spiders also evoke a range of emotions and thoughts from their human cohabitants. If you see one in your house do you squish it? Do you capture it gently and relocate it? Do you run away screaming?...

Last year in spring, we came up with an idea of creating a flower garden that would only feature native plant species. Why is that both difficult and important? And what conclusions can we draw after a full year of watching the flower garden grow and seeing how both community...

It’s July. With the windows down, drive to the corner of Hudson Street and Netherwood Avenue. Pull into the driveway lined with Marigolds and with Morning Glories climbing the mailbox. You might miss the street sign, which is regularly hidden behind Sunflowers 10 feet high, but you can’t miss the...

While the award-winning movie Parasite (2019) by Bong Joon-ho was iconic in many ways, a terrifying scene haunts me more often than others. The scene is one where the one of the central families of the movie, the Kims, rush back to their semi-basement apartment only to discover it is...

How big is your house and property? Is it smaller or larger than you want it to be? Or is it just the right size? Do your house and property give you all that you need? Do you live in a neighborhood with many neighbors or not enough? Are your...

In April of 2022, the New York Times ran a viral piece on its front page entitled Trying Everything, Including Lettuce, to Save Florida’s Beloved Manatees. It details a sordid tale of Floridian Manatees — sea cows — struggling for survival amid a riverine habitat polluted by industrial effluents and...

Informal organizational structures are commonly involved with greening efforts in cities, such as waste recycling and urban agriculture efforts. They are particularly relevant in cities of the Global South, where large percentages of the economy and labour are in the informal sector. Collaboration between the formal and informal sectors poses...

Many cities around the world are planning to enhance urban nature. For example, many global cities have promised to plant a million trees, such as Shanghai, New York, Singapore, and Miami, and there are large tree planting initiatives in Uttar Pradesh, Ethiopia, and China, among many others. But most of...

The portion of the Great Lakes basin ecosystem stretching from southern Lake Huron through western Lake Erie is a unique urban refugium where the tapestry of life has been woven with elegance, where the music of life has been rehearsed to perfection for thousands of years, where nature’s colors are...

  Biodiversity faces increasing challenges with the development of cities. Land-use change, intensive agricultural management and pesticide use, invasive alien species, diseases, climate change, and environmental pollution are threatening bees and other pollinators. Helping them to survive means ensuring food security and maintaining healthy ecosystems. Nature conservation and the improvement...
