Green Infrastructure

What is Green Infrastructure?

Green Infrastructure is an approach that incorporates both the natural environment and engineered systems to create ecological corridors, preserve the natural water cycle and provide a wide array of benefits to people and wildlife. 

Green infrastructure relates to solutions that can be applied on different scales from a building level to a broader landscape level. These practices include green roofs, green walls, infiltration planters, trees and rainwater harvesting systems in urban areas. 

Green Infrastructure Projects 

Green Lamp Post 
  • A new Green Infrastructure concept was introduced in Marsa-Ħamrun Bypass. This concept was composed of the supply, installation and maintenance of green lamp posts.
  • Using existing lamppost columns is seen as a more efficient way of increasing the coverage of plants and greenary in highly urbanized areas. 
  • Can be consired as a ‘Pollution relief’ pillar that is full of plants to mitigate pollution (trapping particulate matter (PM) and Carbon).
  • In this project the smart pillar is being watered using an automatic irrigation system. 

Green Walls
  • Green walls financed and planned by AM were  installed in Industrial Areas (Mosta, Kordin & Marsa), Marsa- Ħamrun Bypass and in Raħal Gdid. 
  • These projects were carried out in collaboration with INDIS Malta, Infrastructure Malta and Paola Local Council.
  • Over 460 metres were covered with a variety of ornamental plants in five different  locatities. 
  • Over twelve variety of plants are used in every green wall including the indigneous: Rosmarinus officinalis, Teucrium fruticans & Santolina spp.

 Projects Benefits 
  • Enhancement of the site’s aesthetic value; 
  • Can also serve to create privacy (a sense of enclosure) while limiting the negative psychological effects associated with property demarcation (especially in Industrial Areas);
  • The vegetated surface provided by strategic urban greenery such as green walls and roofs is able to block high frequency sounds, and when constructed with a substrate or growing medium support can also block low frequency noises;
  • Green walls can help mitigate loss of biodiversity due to the effects of urbanization, help sustain a variety of plants, pollinators and provide habitats for various species, especially in ecological fragmentated urban zones;
  • Green roofs and green walls are usually kept moist to keep vegetation alive, therefore they are likely to be fire-resistant;
  • Dense urban areas are normally affected by the Urban Heat Island Effect, as a result of a temperature difference between a certain urban area and its nearby rural areas. Certain studies indicate that the overall, the average reduction of the surrounding temperature, vary between a minimum and a maximum average of 1 °C to 2,3 °C; and
  • Improving urban spaces with the integration of green infrastructure projects can be used as a tool to promote citizens health and well-being.
