The COVID-19 pandemic revealed how important urban nature is for our physical and mental health. As urban strategists embark on ideas and think of pathways for recovery and “building back better” our societies and especially cities, it is paramount that the green recovery include nature in the mix of options...

Most of the inhabitable regions of the Earth were originally covered by forests, grasslands, and wetlands. These carbon-grabbing, biodiverse, spongy landscapes have been largely replaced by agriculture and urban development, which is drier, belches carbon, is erosive of soils, and which has lost most of its wildlife. Indeed, biodiversity declines...

“Science is meaningless because it gives no answer to our question, the only question important for us: ‘What shall we do and how shall we live?’ ” — Leo Tolstoy  We know that our cities need to look and function differently. There is a wealth of scientific evidence showing that urbanisation...

This contribution is the result of a thought-collecting Seed Session during the TNOC Summit in Paris, held on June 5, 2019. Pitches, group breakouts, and a facilitated discussion addressed the question: Including diverse voices in adaptation planning, how do we make it happen? Two illustrators, Frida Larios and Marion Lacourt,...

Edible urban gardens have gained increasing popularity in the Global North within the narrative of nature-based solutions for cities and as parts of urban green infrastructure, which reintroduce greenspaces and associated functions into built environments, with the aspiration of leading to a socially and ecologically more sustainable city.

This essay advocates for a unique “Youth Empowerment Based Green Recovery Programme” to be developed and adapted by governments to enhance long-term societal resilience. As we have collectively moved towards unlocking the lockdowns and quarantines that had been in effect since March 2020, the world’s attention has been gripped in...

Today’s post celebrates some of the highlights from TNOC writing in 2020. These contributions—originating around the world—were one or more of widely read, offering novel points of view, and/or somehow disruptive in a useful way. All 1000+ TNOC essays and roundtables are worthwhile reads, of course, but what follows will give you a...

As the COVID-19 pandemic accelerates and the prevalence escalates, global health care systems become overwhelmed with patients who are either confirmed or suspected to be suffering from the disease (Chen et al., 2020). Frontline health care workers (HCWs) are required to work for long and irregular hours, with heavy workloads...

Our graduate students are figuring out how to best “immerse” themselves in city spaces while staying safe during the pandemic. Students find creative ways to both learn and practice while masked and distanced from community members. A positive outcome of being online is the ability to invite environmental activists and...

Two incidents stand out particularly from my memories as a young child. In the first one, I was perhaps 5 or 6 years old—at that age when we ran out of the housing colony and into the streets to play a game of hopscotch or whatever else took our fancy....

Writing this during National Forest Week here in Canada, I’m reflecting (as I frequently do) on the urban forest. As a scientist, I often find myself collapsing the beautiful, multidimensional, urban forest into a few general measurements: stand density, canopy cover, biomass, etc. But as an urban resident, I cherish...
