Green and blue infrastructure (GBI) refers to the network of natural and semi-natural spaces and pathways within a city. Think of cities as living organisms, with GBI acting as their veins and nerves amidst the built environment.
These “veins” consist of interconnected greenery, soil, and waterways that make up the city's natural ecosystem, co-existing with urban development. This network supports people, biodiversity, and natural systems, with trees being a crucial component.
