"With “green corridors” that mimic the natural forest, the Colombian city is driving down temperatures — and could become five degrees cooler over the next few decades.

In the face of a rapidly heating planet, the City of Eternal Spring — nicknamed so thanks to its year-round temperate climate — has found a way to keep its cool.

Previously, Medellín had undergone years of rapid urban expansion, which led to a severe urban heat island effect — raising temperatures in the city to significantly higher than in the surrounding suburban and rural areas. Roads and other concrete infrastructure absorb and maintain the sun’s heat for much longer than green infrastructure.

“Medellín grew at the expense of green spaces and vegetation,” says Pilar Vargas, a forest engineer working for City Hall. “We built and built and built. There wasn’t a lot of thought about the impact on the climate. It became obvious that had to change.”

Efforts began in 2016 under Medellín’s then mayor, Federico Gutiérrez (who, after completing one term in 2019, was re-elected at the end of 2023). The city launched a new approach to its urban development — one that focused on people and plants.

The $16.3 million initiative led to the creation of 30 Green Corridors along the city’s roads and waterways, improving or producing more than 70 hectares of green space, which includes 20 kilometers of shaded routes with cycle lanes and pedestrian paths.

These plant and tree-filled spaces — which connect all sorts of green areas such as the curb strips, squares, parks, vertical gardens, sidewalks, and even some of the seven hills that surround the city — produce fresh, cooling air in the face of urban heat. The corridors are also designed to mimic a natural forest with levels of low, medium and high plants, including native and tropical plants, bamboo grasses and palm trees.

Heat-trapping infrastructure like metro stations and bridges has also been greened as part of the project and government buildings have been adorned with green roofs and vertical gardens to beat the heat. The first of those was installed at Medellín’s City Hall, where nearly 100,000 plants and 12 species span the 1,810 square meter surface.

“It’s like urban acupuncture,” says Paula Zapata, advisor for Medellín at C40 Cities, a global network of about 100 of the world’s leading mayors. “The city is making these small interventions that together act to make a big impact.”

At the launch of the project, 120,000 individual plants and 12,500 trees were added to roads and parks across the city. By 2021, the figure had reached 2.5 million plants and 880,000 trees. Each has been carefully chosen to maximize their impact.

“The technical team thought a lot about the species used. They selected endemic ones that have a functional use,” explains Zapata.

The 72 species of plants and trees selected provide food for wildlife, help biodiversity to spread and fight air pollution. A study, for example, identified Mangifera indica as the best among six plant species found in Medellín at absorbing PM2.5 pollution — particulate matter that can cause asthma, bronchitis and heart disease — and surviving in polluted areas due to its “biochemical and biological mechanisms.”

And the urban planting continues to this day.

The groundwork is carried out by 150 citizen-gardeners like Pineda, who come from disadvantaged and minority backgrounds, with the support of 15 specialized forest engineers. Pineda is now the leader of a team of seven other gardeners who attend to corridors all across the city, shifting depending on the current priorities...

“I’m completely in favor of the corridors,” says [Victoria Perez, another citizen-gardener], who grew up in a poor suburb in the city of 2.5 million people. “It really improves the quality of life here.”

Wilmar Jesus, a 48-year-old Afro-Colombian farmer on his first day of the job, is pleased about the project’s possibilities for his own future. “I want to learn more and become better,” he says. “This gives me the opportunity to advance myself.”

The project’s wider impacts are like a breath of fresh air. Medellín’s temperatures fell by 2°C in the first three years of the program, and officials expect a further decrease of 4 to 5C over the next few decades, even taking into account climate change. In turn, City Hall says this will minimize the need for energy-intensive air conditioning...

In addition, the project has had a significant impact on air pollution. Between 2016 and 2019, the level of PM2.5 fell significantly, and in turn the city’s morbidity rate from acute respiratory infections decreased from 159.8 to 95.3 per 1,000 people [Note: That means the city's rate of people getting sick with lung/throat/respiratory infections.]

There’s also been a 34.6 percent rise in cycling in the city, likely due to the new bike paths built for the project, and biodiversity studies show that wildlife is coming back — one sample of five Green Corridors identified 30 different species of butterﬂy.

Other cities are already taking note. Bogotá and Barranquilla have adopted similar plans, among other Colombian cities, and last year São Paulo, Brazil, the largest city in South America, began expanding its corridors after launching them in 2022.

“For sure, Green Corridors could work in many other places,” says Zapata."

Haso: Skateboards and other means of transport

Ek'Gaar couldn't help but stare at young humans enjoying the warm weather. He sat on a bench dressed in his clever dusguise consisting of a trenchcoat and a piece of paper with information on it, and holes for his six eyes. (A disguise like this would make him inconspicuous according to various sources such as enchanted forest of Holly Wood, or the net of inter, whatever that may be)

The kids were moving at high velocities by attaching wheels to their legs in many different ways.

For example the bicycle. A weird metal contraption with moving bits and pieces equipped with a tiniest but at the same time most annoyingly sounding trinket. Some of the kids had ribbons or baskets attached to their bikes as well. Who even came up with it... Had he attempted to ride that monstrocity his tentacles would definitely get stuck between some of the gears.

Another uncanny invention were rolkerskates. Those were even crazier. Who in their right mind would even think of adding wheels to the sole of their shoes... How in the galaxy did it pass any safety tests? And apparently you can have different variations? Wheels in a line, in two lines, with hidden wheel or with a knife... No thank you...

But the most impressive contraption and the one that reigned over the skatepark was The Skateboard. That was something else.. .

Ek'Gaar only ever needed to see one human do the tricks on that damned thing to completely abandon any hope of using that project to create some kind of anti-human weaponry/wehicle. Throckmorton the Skateboarder they called him. That man was what finally broke the alien as he seemingly defied gravity attempting flashy and risky stunts. No thank you, He'd rather keep all his appendages...

Earth is off limits for anybody with even an ounce of common sense, those things should not be tampered with and are clearly unstable...

what do you headcanon the gunnhildr sibs preferences to be? personally i see jean as a cis pansexual and poly (because of you fics thanks for that btw) and barbara to be trans mtf and bisexual

I don't really have a solid headcanon for Jean's preferences beyond that she's into women--I can range anywhere from 'exclusively lesbian' to 'Kinsey-scale-3 bisexual' depending on the story I'm telling myself about her at the time? Like, I have headcanons that I'll flex for fic purposes, but this is more that the only headcanon I have in the first place is that she likes women, and the rest is a nice muddy shape around it. (A muddiness I often like to roll in!) Similarly, I like to write her as poly, but it's not really a 'headcanon' per se, it's just how I like to write her. XD As for gender, though, while this post starts about Kaeya I basically cover it here: technically she's cis in that she's not seeking not to be a woman, but I don't think the axis upon which Jean identifies has anything to do with gender. She'd describe herself as a Gunnhildr and as a knight, as opposed to a civilian, but she wouldn't put 'woman' in a self-description because it's very minimally relevant to how she thinks about herself.

I don't really have strong headcanons about Barbara, because I haven't thought about her from those angles so much; my defaults for her are cis woman and wlw, but I haven't really focused in on either aspect when writing or thinking about her. I definitely can see where an MtF reading would be fun, though, especially in light of a headcanon I do have, wherein the Gunnhildrs are matrilineal. (I mean, the fact that the only four we know the names/identities of are all women could just be coincidence, there's only four we know at all, but 'that's because the men are all married out to other families' is more fun to me. XD) The tensions that would add to her existing family situation--trying to prove herself when she was still a Gunnhildr, being thrust out of the family when her parents divorced (and her father being allowed to take her)--in tragic but interesting ways!

#i feel like i quibble over the meaning of 'headcanon' a lot answering this kind of thing XD;;#but basically a headcanon to me is a structure i use to fill an empty space in the lore/narrative #with such consistency that when telling myself stories it's an underlying part of the framework just as canon is #and i'm making a conscious decision for narrative purposes when i depart from it in a given story #but i like to tell myself lots of different stories and things that change easily as part of that variety aren't headcanons to me #e.g: since jean is my bicycle for this fandom her sexuality isn't because it depends on what story i want to tell with her that day #asked and answered #someone please give jean a nap #sing me a song barbara

Taking in the golden hours on two wheels (of course.) The bikes get some aster flower crowns because ‘tis the season! (The flowers come from my garden of course.)

It won’t be long til these summer bikes are retired for the year, and then hopefully there will be plenty of snow to romp in on the winter bike.

#bicycle commuting #bike stuff #cycling has become part of my personality oops #which means yeah there’s yet another bike here she is #thought the name Gyrfalcon would be appropriate #slap gears on the single speed we want to go fast #Cirrus the space horse still remains the most stupidly comfy bike I’ve ever ridden #yeah I have a problem but there are worse ones to have?#autumn foliage #fall colors #nature #the Mississippi is so low we need rain so damn badly

truly one of the most fun aspects of my job is totally shaking up people’s expectations of what a councillor looks like. and some of them will not respect you for refusing to assimilate but sometimes you meet some ppl your age at a relaunch party for a small charity and they are so excited to have a rep who looks and acts like them and you’re like ah. you’re the guys i do this for <3

#it was one of those spaces specifically designed for me. everybody’s young queer & really into urbanism and zero waste #someone had scrawled dykes on bikes on a pole and for a moment i wished i was a lesbian #you could make a putting the bi in bicycle joke i guess. but that’s not as fun #fieldwork

New hobby, Mars? 👀 what are you up to...

Hehe I'm in the research phase at the moment buuuut I think I'm gonna get into skateboarding. The inner child in me has been dying for it for ages but I never indulged in the thought

#I'm leaning towards a cruiser but still doing my research before I hit the shops since we don't really have a lot of specialized shops here #I really need to partake in more physical activities #and I can't buy a bicycle unless I get a separate apartment first because there's no space for it #which is tragic #I was ready to get one #a bike I mean

for my birthday corey got me this absolutely batshit vintage 90s italian cycling jacket (bomber-jacket style) that had to be shipped from the czech republic. it looks like a 100 gecs song and/or an original-flavour mobile suit gundam fight and i love it so much.

#it is to go with my vintage 80s italian racing bicycle the love of my life my bianchi nuovo alloro #but also my space heist book and my desire to be an anime prettyboy #my face #important placeholder tag #the diary #birthdaying #bicycleblogging

miss the way rose and nine and ten were forever yanking weird bobbles and like, twisting bopit things and slapping a klaxon or whatever when they were trying to drive the tardis and the light inside was always way too orange or way too green and it looked very homemade and cobbled-together . loved that rusty old bucket miss her :’)

#yes yes all iterations are nice #but one thing i really enjoyed about thirteen was that they went back to Weirdly Bright Backing Color Scheme #everyone's faces are lit strangely :)#i really liked it when she was a junky old Contraption just being flung through space on bicycle components and kitchen gadgets #eye spy book looking tardis. that was great #dr who #q
