When you think of a bromeliad, you probably don't think of something that looks like this. Bromeliads of the genus Sincoraea are among some of the strangest that I've ever seen. Almost all are endemic to Bahia, Brazil, where this one was found (one lives in Minas Gerais), mostly from the campo rupestre habitat. They remind me of sea anemones or starfish on the rocks!

"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."

Scientists have discovered cannabidiol, a compound in cannabis known as CBD, in a common Brazilian plant, opening potential new avenues to produce the increasingly popular substance. The team found CBD in the fruits and flowers of a plant known as Trema micrantha blume, a shrub which grows across much of the South American country and is often considered a weed, molecular biologist Rodrigo Moura Neto of the Federal University of Rio de Janeiro told AFP in June 2023. CBD, increasingly used by some to treat conditions including epilepsy, chronic pain and anxiety, is one of the main active compounds in cannabis, along with tetrahydrocannabinol, or THC – the substance that makes users feel high. The compound's effectiveness as a medical treatment is still under research.

Plant of the Day

Tuesday 13 February 2024

A tender, evergreen perennial usually grown as an annual, Acmella oleracea (Pará cress, Brazil cress, eye ball plant, novacaine plant, salad cress, spot plant, toothache plant) has culinary and medicinal uses. The leaves are dark bronzy green and the petal-less yellow flowers are produced from mid-summer to early autumn.

AWESOME SNAKE MAN FACT!

Since he hibernates during winter, he's never been awake to experience New Years Eve...

This means that he's never seen Top man being useful.

"Helio da Silva, a retired business executive from Brazil, single-handedly planted over 41,000 trees in his hometown of Sao Paulo over the last two decades.

Flying over the Brazilian metropolis of Sao Paulo, it’s tough to miss the 3.2-kilometers-long and 100-meter-wide green strip of trees wedged between two of the city’s busiest roads. It is known as Tiquatira Linear Park, and it is the work of a single man who worked tirelessly for over 20 years in order to transform a previously dilapidated area into an actual jungle within the urban jungle that is Sao Paulo. Originally from the town of Promissao, about 500km from Sao Paulo, Helio da Silva was a successful business executive for many years, but after retiring, he took it upon himself to transform the degraded banks of the Tiquatira River into a green oasis for his community. He started planting trees there in 2003 and hasn’t stopped since.

73-year-old da Silva recently told AFP that he wanted to leave a legacy to the city that adopted him decades ago. Within the first four years of his epic project, he single-handedly planted 5,000 trees in an area that had long been abandoned and known to be frequented by drug dealers and users. His impressive feat prompted the municipality of Sao Paulo to recognize his efforts and acknowledge the area as the first linear park in Sao Paulo. This only emboldened da Silva, who continued planting native trees.

By 2020, Helio had planted more than 25,047 trees over a 3.2-km-long area, achieving a survival rate of 88 percent. For every 12 trees, he planted a fruit-bearing species in the hopes of attracting birds and animals to his green oasis. His bet paid off, as according to the municipality, 45 types of birds have been identified in the park. Today, the Tiquatira Linear Park numbers over 41,000 individual trees, and Helio da Silva doesn’t plan on stopping planting until he reaches at least 50,000 of them.

“My motivation comes from the trees themselves because trees give us flowers and fruits, absorb rainwater, attract birds and provide us with wonderful shade and fresh air,” da Silva told Common Earth.

The retired executive estimates that he spent about $7,000 per year on his tree-planting efforts since 2022, but the way he sees it, it was a worthwhile investment for himself, his family and the whole of Sao Paulo. Plus, he saved a lot of money by planting the trees himself.

Once labeled as crazy for spending most of his time planting trees in an area most people avoided, Helio da Silva is now hailed as a local hero. He sometimes receives help from like-minded nature lovers, but he is still the driving force behind this amazing project. Every Sunday, he comes to Tiquatira Park to plant more trees.

Over the years, the city gym and playground equipment, tables, benches, toilets, and Tiquatira Linear Park eventually became one of Sao Paulo’s most popular areas."
