The City of Montreal today announced its ambitious commitment to protecting biodiversity and improving living environments by implementing the principle of zero net artificialization by 2030. The aim of this measure is to compensate for the impact of developments that reduce areas that are home to biodiversity. Two levers will help to combat the loss of biodiversity: density and an increase in green spaces.
Protecting biodiversity
An analysis of plant and mineral surfaces carried out in 2016 revealed that the Greater Montreal area comprised 38% plant and permeable surfaces and 62% mineral and impermeable surfaces. Impermeability of soils strongly alters soil micro-organisms and fauna, contributing to the destruction of the species that live on these territories. By adopting this principle, the city aims to maintain and preserve the existing biodiversity of its territory. The preservation of vegetated areas will take the form of enhancing, restoring and restoring natural or agricultural areas, as well as creating green or ecological corridors. By densifying the city and combating urban sprawl, Montréal intends to protect the soil in order to protect biodiversity.
To increase the role of nature in the city, Montreal's Master Plan for Urban Planning and Mobility includes provisions for the greening and protection of natural environments. Land acquisition by the city is the preferred means of protecting natural environments and extending large parks. Significant efforts are also being made to restore access to the island's riverbanks.
Consequences of soil artificialisation
Soil artificialisation amplifies the risk of flooding, loss of biodiversity, global warming, pollution and the reduction in the capacity of agricultural land to feed us. In cities, vegetation is the best way to cool the air. Replacing planted surfaces with paved ones reinforces heat islands in urban areas.
"Biodiversity plays an essential role in the quality of life and health of our communities, and must always be taken into consideration in any development. With the target of zero net loss of biodiversity on the island of Montreal by 2030, we are equipping ourselves with concrete means of protecting existing biodiversity over the long term. This target will enable us to build Montreal's future effectively and sustainably," declared Montreal Mayor Valérie Plante.
