Description

    Programme Overview and Purpose

     

  • Medellin's Green Corridors programme aims to reintroduce greenspace in urban areas and reduce the urban heat island effect.
  • The programme involves the creation of 30 green corridors across the city, developed along major roads and waterways, and connecting natural features such as the surrounding hills.
  •  

    Green Infrastructure and Design

     

  • The corridors link various green infrastructures like squares, parks, and green curbs.
  • These corridors are designed to resemble forest-like ecosystems, with over 72 native plant species chosen for their ability to remove pollutants, provide shade, and offer fruits.
  • Major concrete structures like metro stations and bridges are being fitted with green roofs and vertical gardens to reduce heat absorption.
  •  

    Cycling and Mobility

     

  • The programme includes 20km of cycling networks within the green corridors.
  • Areas under metro lines have been converted into serene cycling trails with lush gardens beneath the structures.
  •  

    Environmental and Health Impacts

     

  • Medellin has experienced a 2°C temperature reduction after the implementation of the green corridors, along with a decrease in respiratory diseases caused by air pollution.
  • Urban trees and vegetation are recognized as an important Nature-based solution for mitigating the effects of climate change and enhancing the city's resilience.
  •  

    Community Participation and Social Impact

     

  • The corridors are maintained by citizens trained in gardening, including individuals from minority and disadvantaged communities, which promotes public participation and creates livelihood opportunities.
  • The programme emphasises equitable access, ensuring that the green corridors are developed in poorer sections of the city and that local residents play a key role in their upkeep.
  •  

    Pollution Control and Biodiversity

     

  • The strategy begins by targeting areas with high pollution levels, such as main roads, resulting in more immediate improvements.
  • The network of greenery creates a continuous wildlife habitat, helping to conserve biodiversity and promote ecological balance.
