Colombian city managed to reduce the heat with green corridors

The Colombian city that managed to reduce the heat with a network of green corridors is Medellín. In 2016, the city began a project to plant millions of plants and trees along streets and avenues. The goal was to reduce temperatures, improve air quality and create a more pleasant environment for citizens.

The project has been a success. Temperatures in Medellín have decreased between 2 and 5 degrees Celsius in the areas where the green corridors have been planted. In addition, air quality has improved and an increase in biodiversity has been observed in the city.

It is a system of more than 30 green corridors that connect green routes, vertical gardens, streams, parks and hills.

These corridors have bike lanes lining the streets and pedestrians can rest on shaded benches.

"City of the eternal spring"

Given Medellín's temperate climate, the city is recognized worldwide as the "city of eternal spring" and has long helped attract tourists year-round. But growing urbanization faces challenges from the "heat island" effect in which buildings and roads absorb and retain heat, raising temperatures.

However, new green corridors have been shown to be effective in changing these impacts.
According to local government data published by BBC Future Planet, have helped reduce temperatures throughout the city between 2°C and 5°C.

The Medellín green corridors project is an example of how cities can use vegetation to mitigate the effects of climate change. The project has been internationally recognized and has been used as a model by other cities around the world.

Data on the Medellín green corridors project

  • More than 120.000 plants and 12.500 trees have been planted.
  • The green corridors occupy an area of ​​more than 100 square kilometers.
  • The project has created more than 1.000 jobs.

The project offers a popular, low-cost solution that more and more cities are seeking to replicate, as it has proven that vegetation is an effective tool for reducing temperatures, improving air quality and creating a more livable environment.
