"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."

Before you say no duh, remember that we need studies like this to quantify things for planning, government policy, and court cases, and also to help convince people who's minds aren't already made up.

I know I struggle to breath in heat like this, and hypoxia kills, especially when cars are involved.

Ancient redwoods recover from fire by sprouting 1000-year-old buds

Article | Paywall free

When lightning ignited fires around California’s Big Basin Redwoods State Park north of Santa Cruz in August 2020, the blaze spread quickly. Redwoods naturally resist burning, but this time flames shot through the canopies of 100-meter-tall trees, incinerating the needles. “It was shocking,” says Drew Peltier, a tree ecophysiologist at Northern Arizona University. “It really seemed like most of the trees were going to die.”

Yet many of them lived. In a paper published yesterday in Nature Plants, Peltier and his colleagues help explain why: The charred survivors, despite being defoliated [aka losing all their needles], mobilized long-held energy reserves—sugars that had been made from sunlight decades earlier—and poured them into buds that had been lying dormant under the bark for centuries.

“This is one of those papers that challenges our previous knowledge on tree growth,” says Adrian Rocha, an ecosystem ecologist at the University of Notre Dame. “It is amazing to learn that carbon taken up decades ago can be used to sustain its growth into the future.” The findings suggest redwoods have the tools to cope with catastrophic fires driven by climate change, Rocha says. Still, it’s unclear whether the trees could withstand the regular infernos that might occur under a warmer climate regime.

Mild fires strike coastal redwood forests about every decade. The giant trees resist burning thanks to the bark, up to about 30 centimeters thick at the base, which contains tannic acids that retard flames. Their branches and needles are normally beyond the reach of flames that consume vegetation on the ground. But the fire in 2020 was so intense that even the uppermost branches of many trees burned and their ability to photosynthesize went up in smoke along with their pine needles.

Trees photosynthesize to create sugars and other carbohydrates, which provide the energy they need to grow and repair tissue. Trees do store some of this energy, which they can call on during a drought or after a fire. Still, scientists weren’t sure these reserves would prove enough for the burned trees of Big Basin.

Visiting the forest a few months after the fire, Peltier and his colleagues found fresh growth emerging from blackened trunks. They knew that shorter lived trees can store sugars for several years. Because redwoods can live for more than 2000 years, the researchers wondered whether the trees were drawing on much older energy reserves to grow the sprouts.

Average age is only part of the story. The mix of carbohydrates also contained some carbon that was much older. The way trees store their sugar is like refueling a car, Peltier says. Most of the gasoline was added recently, but the tank never runs completely dry and so a few molecules from the very first fill-up remain. Based on the age and mass of the trees and their normal rate of photosynthesis, Peltier calculated that the redwoods were calling on carbohydrates photosynthesized nearly 6 decades ago—several hundred kilograms’ worth—to help the sprouts grow. “They allow these trees to be really fire-resilient because they have this big pool of old reserves to draw on,” Peltier says.

It's not just the energy reserves that are old. The sprouts were emerging from buds that began forming centuries ago. Redwoods and other tree species create budlike tissue that remains under the bark. Scientists can trace the paths of these buds, like a worm burrowing outward. In samples taken from a large redwood that had fallen after the fire, Peltier and colleagues found that many of the buds, some of which had sprouted, extended back as much as 1000 years. “That was really surprising for me,” Peltier says. “As far as I know, these are the oldest ones that have been documented.”

... “The fact that the reserves used are so old indicates that they took a long time to build up,” says Susan Trumbore, a radiocarbon expert at the Max Planck Institute for Biogeochemistry. “Redwoods are majestic organisms. One cannot help rooting for those resprouts to keep them alive in decades to come.”
