Beneath the surface
Ideas about the invisible world beneath the soil have pervaded my thoughts for as long as I can remember. As a child, I read books about the underground homes of animals in books like Mrs Frisby and the Rats of NIMH by Robert C. OâBrien and Fantastic Mr. Fox by Roald Dahl.
Fast forward to 2014, when I made the above drawing attempting to visualise an interconnected web of plant roots. This drawing contains a web of India ink and acrylic gesso sprawling across a 2 meter square of thick paper, whose size and depth fail to translate to this tiny digitised version.
But the real physical version of the drawing too felt like it failed to translate my mental picture into physical formâ failed to inspire the sense of interconnectedness of my vision, and thus never felt finished. Alas, after a few months of work on my web of roots, I gave up, pulled the pins out of the wall and rolled it up. It found its home in a storage closet with the rest of my rejected artefacts, deemed unworthy of display in my home, and yet somehow still too precious to discard. It has remained rolled up collecting dust ever since.
The unrealised vision for this drawing had begun to inhabit my mind after learning about mycelium and mychorrizae for the first time from mycologists in Eugene, Oregon, where I was living and studying landscape architecture at the time. The video below by ecologist Suzanne Simard summarises the knowledge that gave rise to this vision, explaining the astonishing interconnectedness of communities of trees in forests.
Fast forward again to 2020 when one of my Creativity in Design module leaders put a task to the class to fill out sheets of paper with a series of prompts:
âwhen the city was: ___,
what if: ___,
and the city then became: ___.â
Before thinking, I found my hand scrawling a scenario:
âwhen the city was: bombed in World War II,
what if: everyone moved underground,
and the city became: a labyrinth of tunnels.â
My classmates found this idea quite dismal; after all, life underground would not involve much light or fresh air, they aptly pointed out. And yet, I remained inexplicably enchanted by the idea of a subterranean metropolis.
Later in the term, when my design team pivoted away from the idea of a âgame of plant lifeâ and returned to questions about plant agency and plant communication (explored in my last couple of posts), this underground web resurfaced in my thinking.
We found a book called The Hidden Life of Trees: What They Feel, How They Communicate- Discoveries from a Secret World by Peter Wohlleben and learned more about what he called the Wood Wide Web: networks of tree roots and fungi which serve as an infrastructure for the sharing of information and resources.
As the team brainstormed different ideas, we shifted from the design of a game to the design of a site-specific art installation and honed in on the idea of âtiny forestsâ or liminal patches of green space dotted throughout the city. The goal, carried through from our work all term but clarified now, involved engendering human empathy for plants, or in other words fostering the connections between humans and plants. Only now, we were in lockdown as a result of COVID-19.
The COVID-19 crisis has had varying impacts on our lives so far, but the most pertinent felt impact for our team at the time was a pervading feeling of isolation. Fortunately, we were able to keep working together thanks to the internet. We reflected on the notions of isolation and interconnection, and the infrastructures of the city (e.g. the world wide web) that foster our connections in absentia.
Meanwhile, we had to choose a site for our intervention that we knew from memory. We chose to explore hubs of connection where roads, train lines, and people come together in physical proximity but are often disconnected, passing by quickly, unaware of their surroundings. Two sites we knew well were Highbury & Islington and Kings Cross. Since we couldnât visit sites in person, we visited them digitally via Google Earth and Google Images.
We discussed ways that plants communicate and ways that people connect. We brainstormed ideas and sketched them out. We shared concepts in Google spreadsheets. We considered pheromones as one potential concept. Tons of seemingly random ideas and resources were compiled. Among them, I posted a link to a touch-sensitive LED floor while Rosie posted resources about the Wood Wide Webâ what if the sidewalk were a giant screen where people could peer into the underground world of plants? Interesting, but perhaps just a passing pretty picture. We moved on.
Gemma was exploring a vision of a concept of a digital âmother treeâ and posted an exhibit from Japan with relevant resources to that idea, which happened to use stillness (as opposed to movement) as a triggering interaction. And then, in a blurry flurry of ideation, some dots were connected-- what if, on the digital floor of tree roots & Wood Wide Web, humans standing still triggered an interaction⌠what if the people grew roots too⌠that connected to the plantsâ roots?!
We continued to explore other ideas, and I sketched various concepts for mini sites within the greater Kings Cross redevelopment. Among them, a tiny forest at Granary Square, where the roots floor vision unfolded in my sketchbook, and then the realisation: âWait. These treesâ roots wouldnât be connected.â
I knew from my days as a landscape architect that urban trees living amongst pavement are planted in âwells,â which are essentially boxes underground. This made me feel sad. I had a newfound empathy for these isolated plants because of my current isolation during the Coronavirus lockdown.
This reality of tree wells also threatened the vision of an uninterrupted, interconnected web underneath the sidewalks. It would be a lie in most urban spaces.
At the next meeting, we discussed including two sites instead of one and highlighting the juxtaposition of these underground systems. Weâve presented this proposal in a slideshow and produced a document containing a project summary and visual narrative of the design journey.
In the final stages of detailing this design proposal, we connected two more resources, which serendipitously catapulted our concept into a truly radical smart city future.
First, Paul Stamets Mycelium Running: How Mushrooms Can Save The World posits that mychorrizal networks are the âneural networks of nature,â meaning that forests are their own âsmart cities.â Stamets also posits that the networks relay vast amounts of information which can be tapped into by humans, and therefore have potential to serve as âinterspecies interfaces.â
Additionally, the work of Neri Oxman at MIT media lab shows how organic, living matter can be used for building materials among many other innovative uses. Could our internet infrastructures be made of mycelium?
These datapoints led us to expand our vision beyond a world where humans build urban infrastructures in ways that are merely harmonious with plantsâ networks. Instead of harmonious but disparate plant and human infrastructures, it is wholly possible that we could share our infrastructural networks with those of plants and fungi.
With this in mind, Iâll leave you with one last thought:
When: humans and plants lived isolated in disconnected boxes,
What if: we came together to merge the world wide web and wood wide web to form one interconnected network,
And then the city became: a living, growing, shared smart city.
