How does your (rain) garden grow? A mosaic about really green infrastructure

You might recall that climate change is going to mess with precipitation trends (I made a mosaic about it a while back) and, as a result, some areas of the world will experience more intense downpours. In cities, which tend to be covered with a high percentage of impermeable surfaces (think roads, rooftops, parking lots, etc.), this water can’t soak in, so we have to direct it somewhere using man-made solutions, like storm sewers. When our storm sewers get overwhelmed by a big rainfall event, we can end up with flooding in our streets and our basements.

As these downpours become more intense and cities continue to expand (thereby increasing the surface area covered by concrete, asphalt, and the like), local officials are finding that they’re having to deal with increasing stormwater runoff. One option is to build bigger and bigger storm sewers, but that sort of hard infrastructure can get pretty expensive and you’ll always be playing catch-up as the climate continues to change. A better (and complementary) option is to manage the rain where it falls. Slow it down. Let it soak in. And what’s naturally built to do that? Plants are! Leaves slow down the falling rain, while roots and the soil let it soak in. Not only does this help redirect water away from our storm sewers and avoid overburdening them, but it also helps recharge our groundwater.

Back when I worked on adaptation (which seems like ages ago but in reality was less than a year ago), I had a huge crush on green infrastructure. It just makes sense: it’s cheaper, it comes with a whole bundle of co-benefits, and it actually gets stronger / appreciates with age. Now, when I say “green infrastructure” I’m talking about really green infrastructure (natural infrastructure), like trees and plants and things, not “green infrastructure” the way the current federal government is using the term (to mean environmentally beneficial infrastructure, like public transit or energy efficient housing). Not that there’s anything wrong with the latter definition, I just find coopting an already-established term a bit…confusing. Anyway, we’re talking plants here and using them to solve a problem we’ve created by letting them just do what they do.

There are lots of ways to team up with nature to deal with climate change impacts, like extreme precipitation, heatwaves, and drought, as well as reaping other benefits, like expanding wildlife habitat, creating recreation opportunities, improving air quality, etc. But the specific focus of this mosaic was how rain gardens (and bioswales, which are kind of just big rain gardens but with a much cooler sounding name) can help deal with extreme precipitation.

Rain gardens are pretty much what you think they are: gardens designed to soak up rain. They’re typically located in lower-lying spots / depressions in your yard where the rain would tend to pool naturally and/or in line with your downspout so they can catch the water coming off your roof (rain barrels are also good for this). You can dig the area out and add soil or other filler that will allow it to better soak up the rainwater like a sponge, and then you add plants that are water-loving. It’s as easy as that! (The City of Guelph has a good little primer / guide here.)

Water swirling around and around…

In this mosaic, these low-lying areas—prime candidates for rain gardens—are represented through an undulating surface full of swells and valleys. The lines swirl away from the asphalt sections at the tops of the undulations (where the water can’t soak in), running downhill and getting greener and wetter as you move toward the pools at the bottoms of the depressions.

A better look at the asphalt (which was NOT fun to work with)

In the KW area, if you’re looking for help with this sort of undertaking, check out REEP Green Solutions. They offer information and workshops on building your own rain garden and on other green living solutions. They’re a fantastic local resource and you can actually see many sustainable solutions in action at the REEP House for Sustainable Living. And, if you live in Kitchener or Waterloo (and a growing number of other municipalities), you can even reduce the stormwater charge you pay to the city if you install a rain garden (or other stormwater management features).

In short: rain gardens look pretty, help your community deal with stormwater (including keeping your basement dry), and save you money. Not a bad deal!

These boots: A personal mosaic geography of life on foot in Ottawa

I have gone the vast majority—we’re talking 98% majority—of my life without owning a car. I loved our car-free lifestyle, and it was a bit of a source of pride. But when we moved from Ottawa to Kitchener, we finally had to cave and buy our first car, since Kitchener, as a whole, is far more car-centric than Ottawa.

Year 1 of car ownership has been a bit of a difficult transition for me. Walking used to be my primary mode of transportation, with public transit, biking, and car sharing also thrown in for good measure. On any given weekday, my feet would carry me a minimum of 6 kilometres from home to the office and back. That’s at least 30 km per week, 120 km per month, and well over 1,000 km per year.

I walked in the glaring sun, the pouring rain, and the bitter cold. Walking the same path day after day, I got to know my landscape, my Place, intimately. I also got time to think. Walking for me is meditative and, as an introvert, is one of my favourite ways to recharge. It also doesn’t hurt that I stumble upon some pretty neat mosaic materials when walking.

I now telework and my commute is much shorter. Just the 14 stairs from the bedroom down to the office. I still get to walk the dog, but he’s gotten older and isn’t as spry, so the walks are slower and we don’t range as far afield anymore. And then there’s this confession: it is SO easy to fall into the trap of driving everywhere.

I’ve noticed a difference in myself, in both my fitness (no more exercise built into my daily routine by default) and in my mental state (no more automatic recharge and quietening of the mind while walking). So I’ve decided to work on rectifying the situation. Since I’m asking Kitchener residents to commit to taking one action to address climate change and then make a mosaic about it for my project, I figured I should lead by example. So one of my personal commitments is to walk/bike more (really, to drive less).

This will, of course, help reduce my carbon footprint significantly, especially given that nearly one quarter (24%) of Canada’s GHG emissions come from transportation. The transportation sector is second only to the oil and gas sector (*cough* tar sands *cough*) in terms of total emissions nationally. And here in Waterloo Region, it’s actually Number One. So there’s a lot of room for improvement. I can certainly do my part.

This mosaic is actually a map of my walking routes from my last few years in Ottawa, with some of the most important places marked: home, work (x2), the grocery store, the gym, the bus station (for those weekend trips to Montreal to visit R), the graffiti wall (one of my favourite foraging places in Ottawa), and, of course, Parliament Hill.

“The paths most travelled” (2017), 26.5″ x 24.25″ — Redback boot (right), Bogs boot (left), cement, shale, limestone

To build the map, I used urban-sourced materials, like cement, my favourite black limestone from Ottawa, and bits of stone that had flaked off a landscaping rock around the corner from our apartment. I also used my own boots, which I had worn out completely walking these and other paths.

The boots before they went under the knife…

The Bogs kept my feet toasty warm on those frigid winter walks, even when the temperature dipped below -40oC. They began and ended their life on the paths in this mosaic map. I wore them until they had a hole in the sole and water started seeping in (and even then, I put a bag on my foot to get a few more kilometres out of them!). Yes, they were good boots.

The Redbacks never actually set foot on these paths, having been retired years before but kept for sentimental reasons (I had bought them when on exchange in Australia in my undergrad and they had a special place in my heart). They saw me through lots of adventures, including my weekend at Touchstone, which is actually probably one of the very last times I wore them. I get a kick out of knowing that these boots, which had travelled so many paths, were there when I took my first tentative steps toward “walking the line” (as Rachel Sager would say) in the Pennsylvania countryside. I could think of no better send-off for both of these boots than to be immortalized in mosaic.

Here’s home base (the place marker on the upper right)

Rubber, stone, and even leather!

I’ve written before about the connection that I see between walking and mosaic, about the “parallels between what I experience when I’m moving through my landscape on foot and what I experience when I’m simultaneously creating and discovering the pathways of my own mosaics.” But this piece, where walking and mosaic came together completely, was one of the purest forms of line-building I’ve ever experienced in my years of working in mosaic. I don’t think that’s a coincidence.

The pure joy of line-building

Making this mosaic was a reminder: of all the places these boots have been, of my time in Ottawa, of the joys of walking, and of the fact that I can (and need to) do better to fight the pull of the car.

Right-size your life, reduce your climate footprint: A mosaic about how size matters

Once upon a time, I made a mosaic about the idea of having “enough” as part of my Fiddling While Rome Burns climate change series. I decided I was going to use one rock and only one rock (and every last scrap of it) to prove that it could be enough. Well, we all know how that turned out: I had too much.

Since that piece—(More than) Enoughis being shown in this year’s Mosaic Arts International exhibition in Detroit, I thought it would be appropriate to make my piece for the Mosaic Art Salon (a silent auction during the annual conference) in the same vein.

Swoon-worthy mookaite, pre-chopping

I chose a beautiful piece of mookaite courtesy of Marian Shapiro that had been sitting on my shelf since last year’s conference, knowing that this would be the right way to do justice to this gorgeous material. One of the reasons I love this “enough” approach to making a mosaic is that it really allows you to celebrate the material and its unique personality. For instance, the mookaite cut very differently compared to the limestone that I used for (More than) Enough—it was so much more irregular, which definitely forced me out of my comfort zone.

“Enough (Size matters)” (2017), 12″ x 12″ — one single piece of mookaite

The substrate was too big for the size of the mookaite. I knew this from the start. By the title, Enough (Size matters), you might think that this is a commentary on the rock being too small. You would be wrong. This is about the substrate being too large. It is about resisting the urge to fill the space with stuff for stuff’s sake. It’s about looking at your lifestyle and evaluating what’s really necessary to meet your needs. Do you have three extra bedrooms because the kids have left home and now you’re empty-nesters? Does each adult in the house really need his or her own SUV just to go to the office and back? Do you really need to buy another pair of shoes just because there’s still room in your closet? This about making sure your stuff, broadly speaking, is the right size for your life. Those offering advice on weight loss often tell us to use smaller plates and bowls to help control portion size. It’s a nifty mind trick, and it also works with consumption in general.

So, this mosaic’s message in a nutshell: use quality things, use them to their best and fullest, embrace minimalism and the space to breathe, relish what you have rather than fixate on what you lack, and, if you can, downsize where it makes sense.  It’s as simple as that and the climate will thank you for it.

Quite possibly my favourite pair of tesserae in the whole piece. Look at those triangles!

Cropped to the ‘right size’… ;-)

You emit what you eat: A mosaic about food choices and climate change

This is not a mosaic about cow farts. I mean, sure, that’s part of it, but the greenhouse gas (GHG) emissions that result from our food choices are far more complex than just some passed gas. There are all sorts of ways to reduce the climate impact of our eating habits, but this mosaic focuses on meat consumption. Please rest assured: I am not trying to pry your steaks out of your cold dead hands. I am not saying it’s vegan or bust. I am simply advocating for moderation. For a wee bit of restraint.

There are GHG emissions associated with everything we eat, from lentils to sirloin to apple pie. More than one quarter of the world’s emissions come from our food system—growing and harvesting the food, transporting and storing it, processing it, and then disposing of it—and about 80% of these emissions come from raising livestock. Among the biggest culprits is red meat: on a serving-to-serving basis, beef has a carbon footprint 6 times larger than poultry (though cheese is also pretty emissions-intensive). Essentially, the higher up on the food chain you eat, the more you emit. Of course, there are all sorts of qualifiers, like how your meat is raised (e.g., factory farm vs. small-scale pastured), how far it travels, how much of it you eat, and yes, how much it farts, but the simple fact remains: when it comes to meat, it takes calories to make calories. And as those calories move up the food chain, there is always waste. There is never a perfect transfer of energy from grain to animal to our plates—animals “waste” energy by doing animal things like frolicking in the pasture (if they’re lucky enough to live in one and not in a feedlot).

Emissions from food are projected to increase as consumption rises and as more people adopt a more meat-based diet. But opportunities abound to reduce food-related emissions. A 2016 study estimated the emission reductions possible under four different scenarios: (1) business as usual, (2) most people abstain from red meat and poultry, (3) most go vegan, and (4) people follow food guidelines set out by the World Health Organization and eat only the calories they require, focusing on fruits and vegetables and small portions of meat. If everyone just followed those sensible food guidelines, emissions in 2050 would be 29% lower. If they skipped the red meat and poultry, the decrease would be 55%, and it would be a whopping 70% if we all went vegan.

But like I said at the beginning, I’m not going to take a hardcore stance and insist that we all become vegans. Heck, I’m not even a vegan. I’m not even 100% vegetarian! I guess I’d call myself a flexitarian, but I “flex” only very occasionally, and generally only for “happy meat” (meat that’s been raised sustainably). To me, Michael Pollan said it best when he said: “Eat food. Not too much. Mostly plants.”

Julie Sperling mosaic about climate change and meat consumption

“Pollan’s Rule (Mostly Plants)” (2017), 20.25″ x 15.25″ — bones, shale, dishes, gold smalti

This mosaic is about the third part of that quote. The bones were sourced from meat-eating friends. Before they made their way to me, they were used to make beef and turkey stock, a rack of lamb, pork chops, and even chicken wings. Here you’ll see them surrounded by shale as a nod to the emissions associated with them. And it’s important to note that on the central “plate” there are still bones, just not all that many. Like I (well, Pollan) said, mostly plants.

There is something fascinating and beautiful but oddly unsettling and a bit macabre about the bones. In this context, they are thoughtfully used and treated with respect, which is basically how we should treat the meat in our diet: with care and reverence.

Oooooh! Eeewww!

The dishes that make up the rest of the mosaic were ours. Two plates from our university days, a favourite mug that took an unfortunate tumble in the dishwasher, and a chipped creamer that we finally replaced. It was important to me to use our dishes. They represent various points in our lives, dietarily speaking. They represent the progress we’ve made. They were with us when we phased out most of the meat in our diet. They were with us as we gradually became more and more committed to buying local and organic and cooking our food from scratch (as Pollan would say, “Eat food.”). They were there when I quit taking milk in my coffee, cold turkey. Over the years, our diets have become much more climate friendly, which we feel pretty darn good about.

Cherished dishes that have seen our eating habits change, now being used in a mosaic that will hopefully inspire others to make a change

I’m not asking you to become a vegan overnight. Just to cut back a bit. Try Meatless Mondays. Commit to buying “happy meat”. Treat meat as a side dish, not the star attraction. And gosh darn it, eat some lentils.

Powering change: Energy production and consumption as seen through mosaic

Energy is, in large part, what got us into this climate change mess in the first place. The burning of fossil fuels like coal, natural gas, and oil has not been kind to the climate. So naturally, changing how we produce and consume energy—shifting to sustainable energy sources and reducing our consumption—will be an important part of taking action to reduce our climate footprint.

Let me be clear: when I’m talking about green or sustainable energy, I am not talking about things like “clean coal” (which is total greenwashing) or fracked natural gas (as much as some would like to tout this as a ‘transition fuel’ and celebrate its contribution to energy independence). No, when I talk about green energy, I am talking about truly renewable forms, like solar, wind, tidal, hydro (but more in the realm of micro-hydro and run-of-river than large-scale hydro), geothermal, and, in some cases, biomass. Yes, these all have an environmental footprint, as (fossil fuel industry–funded) opponents are fond of pointing out. There are impacts associated with the sourcing materials (e.g., mining) and production, with its transportation and construction, operation (e.g., impacts on wildlife like birds and bats), maintenance, and decommissioning. But anything we do—any form of energy we produce—has an environmental footprint, and the environmental footprint of renewable forms of energy is substantially smaller than that of fossil fuel energy. Of course, the greenest form of energy is the energy we don’t use at all and therefore don’t have to produce in the first place, also known as negawatts (‘negative megawatts’—a term coined by Amory Lovins in the 1980s).

“Power dynamic (Renewable production, mindful consumption)” (2017), 22″ x 11″ — marble, litovi, smalti, knob and tube, solar panel, shell, shale, limestone, sandstone, ceramic, miscellaneous stone

This mosaic tackles both renewable energy and sustainable consumption. Starting at the top, there is wind power, complete with clouds made of broken tubes from old knob and tube wiring (which were found in my dad’s garage, of course). Next up is solar power in the form of shiny rays of gold smalti. After that is all water-related forms of energy, but note that there’s lots of motion in the water (thanks to some waves made out of some really amazing shells)—no large problematic dams and reservoirs here!

Knob and tube clouds and golden sunny rays! (Plus negawatts. They’re everywhere!)

Sitting on the ground, there are solar panels ready to catch the sun’s rays above. These were originally part of solar-powered plastic flowers that decorated my grandma’s planter box, but when they broke I scooped them up rather than send them to the landfill. Around the solar panels is a layer of biomass, which, if done properly, is another source of green power (‘properly’ meaning not displacing food production or leading to deforestation, among other factors).

Water, solar, and biomass. Check, check, and check!

And finally, down into the earth for geothermal energy, with hints of the heated groundwater that will be tapped into to produce energy. And we can’t forget the negawatts! You’ll see small sections throughout the mosaic where there are just the impressions left by missing pieces. If we consider each individual piece in this mosaic as a megawatt (a unit of power), then those missing pieces are the negawatts: integrated throughout and an essential part of a comprehensive energy strategy.

The geothermal portion — the heat from the earth’s core and the hot water that will be tapped into

Energy is a really easy area to take action on. You can buy green energy, you can install solar panels on your home, and you can also make your home more energy efficient through renovations (e.g., putting in extra insulation, sealing cracks, planting shade trees, etc.), technology upgrades (e.g., installing a smart thermostat, getting rid of that inefficient beer fridge), and behavioural changes (e.g., hanging your clothes to dry, turning off lights when they’re not in use, putting on a sweater and keeping your house a little cooler in the winter). There are usually incentive programs around to encourage you to implement these actions, so check with your local utility company or various levels of government. The nice thing about reducing your energy consumption is that it usually saves you money in addition to helping you feel very virtuous. Bonus!

And with that, I’m off to my renewable energy–powered studio to create my next climate change mosaic…
