Article

"Cassiano is the founder of Teto Verde Favela, a nonprofit that teaches favela residents how to build their own green roofs as a way to beat the heat without overloading electrical grids or spending money on fans and air conditioners. He came across the concept over a decade ago while researching how to make his own home bearable during a particularly scorching summer in Rio.

A method that's been around for thousands of years and that was perfected in Germany in the 1960s and 1970s, green roofs weren't uncommon in more affluent neighborhoods when Cassiano first heard about them. But in Rio's more than 1,000 low-income favelas, their high cost and heavy weight meant they weren't even considered a possibility.

That is, until Cassiano decided to team up with a civil engineer who was looking at green roofs as part of his doctoral thesis to figure out a way to make them both safe and affordable for favela residents. Over the next 10 years, his nonprofit was born and green roofs started popping up around the Parque Arar�� community, on everything from homes and day care centers, to bus stops and food trucks.

When Gomes da Silva heard the story of Teto Verde Favela, he decided then and there that he wanted his home to be the group's next project, not just to cool his own home, but to spread the word to his neighbors about how green roofs could benefit their community and others like it.

Relief for a heat island

Like many low-income urban communities, Parque Arará is considered a heat island, an area without greenery that is more likely to suffer from extreme heat. A 2015 study from the Federal Rural University of Rio de Janeiro showed a 36-degree difference in land surface temperatures between the city's warmest neighborhoods and nearby vegetated areas. It also found that land surface temperatures in Rio's heat islands had increased by 3 degrees over the previous decade.

That kind of extreme heat can weigh heavily on human health, causing increased rates of dehydration and heat stroke; exacerbating chronic health conditions, like respiratory disorders; impacting brain function; and, ultimately, leading to death.

But with green roofs, less heat is absorbed than with other low-cost roofing materials common in favelas, such as asbestos tiles and corrugated steel sheets, which conduct extreme heat. The sustainable infrastructure also allows for evapotranspiration, a process in which plant roots absorb water and release it as vapor through their leaves, cooling the air in a similar way as sweating does for humans.

The plant-covered roofs can also dampen noise pollution, improve building energy efficiency, prevent flooding by reducing storm water runoff and ease anxiety.

"Just being able to see the greenery is good for mental health," says Marcelo Kozmhinsky, an agronomic engineer in Recife who specializes in sustainable landscaping. "Green roofs have so many positive effects on overall well-being and can be built to so many different specifications. There really are endless possibilities.""

Pictured: Summer heat has been known to melt water tanks during the summer in Rio, which runs from December to March. Pictured is the water tank at Luis Cassiano's house. He covered the tank with bidim, a lightweight material conducive for plantings that will keep things cool.

A lightweight solution

But the several layers required for traditional green roofs — each with its own purpose, like insulation or drainage — can make them quite heavy.

For favelas like Parque Arará, that can be a problem.

"When the elite build, they plan," says Cassiano. "They already consider putting green roofs on new buildings, and old buildings are built to code. But not in the favela. Everything here is low-cost and goes up any way it can."

Without the oversight of engineers or architects, and made with everything from wood scraps and daub, to bricks and cinder blocks, construction in favelas can't necessarily bear the weight of all the layers of a conventional green roof.

That's where the bidim comes in. Lightweight and conducive to plant growth — the roofs are hydroponic, so no soil is needed — it was the perfect material to make green roofs possible in Parque Arará. (Cassiano reiterates that safety comes first with any green roof he helps build. An engineer or architect is always consulted before Teto Verde Favela starts a project.)

And it was cheap. Because of the bidim and the vinyl sheets used as waterproof screening (as opposed to the traditional asphalt blanket), Cassiano's green roofs cost just 5 Brazilian reais, or $1, per square foot. A conventional green roof can cost as much as 53 Brazilian reais, or $11, for the same amount of space.

"It's about making something that has such important health and social benefits possible for everyone," says Ananda Stroke, an environmental engineering student at the Federal University of Rio de Janeiro who volunteers with Teto Verde Favela. "Everyone deserves to have access to green roofs, especially people who live in heat islands. They're the ones who need them the most." ...

It hasn't been long since Cassiano and the volunteers helped put the green roof on his house, but he can already feel the difference. It's similar, says Gomes da Silva, to the green roof-covered moto-taxi stand where he sometimes waits for a ride.

"It used to be unbearable when it was really hot out," he says. "But now it's cool enough that I can relax. Now I can breathe again."

The human body's response to HRT is actually admirable in the sheer indifference. Just pure I Don't Give A Shit, I Just Fucking Work Here compliance to the new instructions. You can get testosterone injected straight into your body and it doesn't even question where that shit came from, coming back from a coffee break and just going

"Okay, everything seems to be in ord- oh fuck now what? Oh huh. Alright fine. New orders came in, cancel the menstrual cycle. Dig up the genetic balding patterns from somewhere, I don't fucking know they're buried somewhere in the dna. I'm greenlighting the growing-hair-on-your-toes thing. Yeah just cancel the ongoing maintenance processes, new orders came in so this is apparently what we're doing now."

I think one of the best things I've learned since getting into fiber arts is that something can be absolutely not my taste and I can still be impressed and delighted for the person who made it and people who love it. Almost every time I look through patterns or projects, I have a thought like, "I hate that and it's magnificent" or, "I wouldn't wear that, but HOLY CRAP it's amazing that you made it."

We need more of that.

flower language has always been an intense source of disappointment for me

like, they all mean really generic things like “love” or “forever” or “i’m sorry” 

i thought you could combine flowers

like you could just send someone a bouquet and from the combination of hibiscus and posies and tulips they’d understand “the rebel leader is dead, rendezvous at the docks at 8, bring the dog, you will need lighter fluid and  a large tomato”

i do think that one of the worst things “activist” spaces on the internet ever did was convince young marginalized people that individual people, complete strangers, were their oppressors. no, matt from chemistry class isn’t personally oppressing you because he’s a guy, that old lady at the bank isn’t personally oppressing you because she’s cis, your waiter isn’t personally oppressing you because they’re white. individuals can and do contribute to systems of oppression. but seeing random individuals you encounter in your daily life as your oppressors will do nothing but trick you into punching laterally or punching down because you think it’s “empowering.” you might get a momentary rush of endorphins from snapping at the male cashier bc #menaretrashuwu but all you’re doing is being shitty to a random guy making poverty wages.

i saw a tik tok the other day that like perfectly described this phenomenon, how gen z (and some young millennials too tbh) pushes for systemic justice and equality, but refuses to give that on an interpersonal level, and like. y’all. you simply cannot achieve systemic change if you’re not also working toward interpersonal change. you will do more for your own liberation by treating others with sensible patience and kindness than you will pushing this toxic individualist narrative of “i don’t owe anyone anything and i get to act however i want to people i view as my oppressor.” we need class solidarity now more than ever.
