Green Virus, Medellin, Colombia

Medellín has been facing high levels of pollution and constant replacement of green areas by gray infrastructure. The Green Virus seeks to increase green areas in the city of Medellín by building a series of “green parks” made up of vegetation, furniture with recycled materials and art. This project aims to improve the environmental conditions of the city and the quality of life of its inhabitants, guarantying spaces for recreation and to strengthen community ties.

The information on this project was compiled by students from the University of Geneva as part of the Urban Futures Workshop (full report).

Target audience

The project's green parks are for everyone, but some projects have a more specific target audience, such as the children’s playground in Niquitao.

Type of actions

  • Temporary reversible interventions
  • Participative process
  • Experimental and innovative strategy
  • Transforming the way citizens perceive their city

Citizen participation

This project was initiated by citizen’s collective creativity. When a street/space lacks green areas, Ciudad Creativa reaches out to find a community willing to work collaboratively to improve their neighborhood (“co-creation project”). Then, green parks are co-produced with the help of many neighbors and volunteers.

Type of intervention

  • Urban design / street intervention: Urban furniture (recycled materials), Art and Painting
  • New activities: social gatherings, children’s playground, painting workshops (flowerpots, walls, streets)
  • Environment: Vegetation


This project is a “green lung” for the city. Parks are based upon environmental research in such a way that it increases its environmental effectiveness.

As of 2016, it had already planted more than 15 trees and 230 species of plants.


The initial idea of increasing green areas throughout the city was achieved. People hope it will continue to transform other parts of the city for a greener and more humane city.
Green Virus is described as a highly successful project due to its appropriation by citizens. Both private and public entities regard it as an economical and intelligent way to revitalize Medellin’s spaces.
