In Colombia, Medellín has transformed its urban landscape through the Green Corridors project. This initiative, which began in 2016, has dramatically improved the city’s environmental and public health. By planting nearly 900 thousand trees and 2.5 million plants, the city has created an urban oasis that supports biodiversity and combats air pollution effectively. A standout feature is the selection of 72 species of plants and trees, specifically chosen for their ability to enhance biodiversity and withstand pollution.
The efforts have led to a noticeable decrease in the city’s temperature by 2 degrees Celsius in just three years, with further reductions expected. Involving community members, including disadvantaged individuals trained in gardening, the project provides new skills and jobs. More green spaces encouraged cycling and wildlife return, demonstrating urban greening’s diverse benefits. Medellín’s green approach can guide other cities towards a healthier, sustainable urban future.
