Medellín's green corridors, how a Colombian city is addressing urban heat by planting trees

In Medellín, the second largest city of Colombia, a green revolution is happening to combat rising urban temperatures. Through the creation of "Green Corridors," the city has witnessed a 2°C drop in temperatures in just three years.
The project, costing $16.3 million, has seen over 2.5 million plants and 880,000 trees strategically placed to maximize their impact. At the heart of this initiative are citizen-gardeners, whose tireless efforts, alongside specialised forest engineers, ensure the corridors thrive. Trained in horticulture and landscaping, these individuals, often from marginalised communities, are carrying Medellín's green revolution.

The benefits extend beyond temperature reduction. The corridors have led to a decline in air pollution, with PM2.5 levels dropping significantly. Cycling rates have surged, thanks to new bike paths, while biodiversity studies reveal the return of wildlife to urban spaces. Inspired by Medellín's success, other cities are adopting similar initiatives.
But challenges remain, including maintenance and funding issues. Despite this, Mayor Gutiérrez is committed to expanding the project and embracing innovative solutions. What an inspiring story for the Colombian city, showing that when there is intention and citizens engagement so much can be done!

          Wow! Less heat, less pollution, more biodiversity and more bikes. This sounds like an obvious gameplan for cities around the world.

              A 2°C drop in just 3 years, that's incredible. Love to see cycling on the rise too! This is exactly the kind of green infrastructure we need #CitiesForTheFuture

                The beauty of the city should be envied by other states and encourage them to do even better.This will reduce urban heat in a major way.

                    Wow, when I read about this first I was wondering, why are more cities not doing this? I realise now that the commitment required by both the leadership and the people to take care of these trees and to nurture them takes a lot of effort and not many people are willing to do so. This is lovable from Medellin

                      It's heartening to see marginalized communities actively participating and benefiting from this green revolution.

                        @princess_nel_268 This has to put a smile on the face of anyone who cares about the planet, to see the landscape of a city change for the better due to efforts of the masses is exceptional.

                          Medellín's initiative of creating green corridors to combat urban heat by planting trees showcases a proactive approach to urban sustainability. By integrating nature into the city landscape, Medellín not only addresses environmental challenges but also enhances the quality of life for its residents. Other countries should follow their footsteps.
