Green sites have flourished in big cities, whether they are planted on the roof of a tall building in New York, in a Milan building, or on the ground level in the Saudi desert, or in the streets of Medellin.
There is a consensus in the world today on the need to restore nature to cities, as urban areas constitute a source of about 70% of greenhouse gases, and regardless of the pace of reduction, it is expected that the devastating effects of global warming on nature and living organisms will accelerate, and become tangible before Long into 2050, according to a draft report prepared by United Nations climate experts.
Today, the world is witnessing a momentum in the field of urban greening, and thanks to green walls and roofs, the temperature can be reduced in nine cities around the world, by between 3.6 degrees and 11.3 degrees Celsius in the hottest times.
concrete trees
The site "The Gardens by the Bay", located near the new business district in Singapore, for example, includes 18 giant concrete "trees" covered with lush vegetation, ranging in height between 25 and 50 meters, and topped with solar panels that allow them to be illuminated at night, looking like flying saucers.
As for the “flower dome”, it is a huge agricultural tent made of steel and glass, embracing a colorful botanical garden that includes tens of thousands of rare plant species from five continents.
The Cloud Forest consists of an artificial mountain with a waterfall, and plants that usually grow at an altitude of 2,000 meters.
rooftop cultivation
Rooftop cultivation amid tall buildings, tall chimneys and four-lane roads. Below are fields planted with radishes, leeks and lettuce on a plot of more than 14,000 square metres. It is one of the largest rooftops in the world, located on the ninth floor of a building in Sunset Park. in New York.
This open farm for those wishing to take a walk and buy vegetables, contributes to reducing heat, improving air quality, and enriching biodiversity, as small birds are seen pecking seeds, and other predatory birds such as red-tailed hawks.
"Vertical Forest"
The vertical forest in Milan "Bosco Verticale", covers an area of two hectares, but vertically, and includes 20 thousand plants and trees distributed over two buildings in the center of the Porta Nuova neighborhood.
On each balcony of these two buildings grow dozens of plants or trees, such as larch, cherry, apple, olive and beech, distributed according to their ability to resist the wind and the most suitable conditions for it, in terms of light or moisture.
The Bosco building was completed in 2014, and in 2015 it received the award for the most beautiful building in the world from the Council on Tall Buildings and Urban Residential Areas in Chicago.
The 7,000-square-meter vertical farm is filled with shelves on 14 levels, 10 meters high, and lit by a total of 20,000 LED lights.
Annually, this farm produces an average of 15 crops of vegetables and herbs.
The seed-bearing and gardening farm is handled by robots in a barn farm in Copenhagen's Tastrup industrial district, which was opened in December by Danish start-up Nordic Harvest.
The green corridors of the Mediencante The Medellín roads in Colombia are deprived of nature, dominated by heat, and left to waste or drug addicts, but have been transformed into 30 “green corridors” planted with trees and flowers, “connected” to a network of already existing green spaces, from public parks or Lawns to private gardens.
This green network project has allowed Medellin, Colombia's second-largest city, to reduce the temperature by two degrees Celsius, to help purify the air, bring back bees and birds, engage residents and create jobs, according to a video of the municipality that has supported the project since 2016.
The project received a number of awards for its contribution to “improving biodiversity,” “reducing heat,” and promoting “the well-being of citizens,” according to the C40 Cities website.
Building Package
A bouquet of green buildings in Chengdu, China From above, the scene in Chengdu, the capital of Sichuan Province in southwest China, looks like a bouquet of green buildings amid stone and concrete.
They are eight green buildings, planted with lush vegetation on their balconies, as part of a pilot project launched in 2018, called "Kiei Forest Park", above a four-lane highway.
Some apartments look like tree huts, in the middle of the rainforest, with birds chirping.
“The air quality is good in the morning,” says Lin Dingjing, a resident, noting that seeing “these trees full of greenery” makes elderly people like him feel comfortable.
