“Central Stockholm has around 12,000 planted trees in its street environment. During the second half of the 20th century, the circumstances for the city’s trees changed dramatically as competition for land increased. Concrete and asphalt were laid closer and closer to the tree trunks. This project aimed to improve conditions for trees in the city’s urban environment as they are very important to the cityscape and the air environment. They also bring residents joy and a sense of well-being. Moreover, this is a way of increasing biological diversity.” The intervention is part of the 'Environmental Billion project'. (Ref. 1, 2). No new data found for this project in 2020. Many similar initiatives have been taken up in the city in other parts, but it is unclear whether they are part of the same project or are separate projects.
Overview
Nature-based solution
- Grey infrastructure featuring greens
- Alley or street trees and other street vegetation
Key challenges
- Water management (SDG 6)
- Flood protection
- Green space, habitats and biodiversity (SDG 15)
- Green space creation and/or management
- Environmental quality
- Air quality improvement
Focus
Creation of new green areas, Maintenance and management of urban nature
Project objectives
- Create and strengthen the green 'wedge' through the city between Brunnsviken and Nybroviken bays.
- Link parks and street spaces and provide conditions for a green corridor through the city, and thereby increase biodiversity.
- Increase the amount of leaf and leaf volume of 416 of the inner city's street trees.
- Reduce air pollution in the inner city.
- Increase the ability of the trees to bind air pollutants.
- Reduce the load on recipients for rainwater.
- Increase the infiltration and purification of rainwater in the existing environment.
- Reduce the load on the water management system.
- Reduce damage to VA-lines and surface coatings caused by trees. (Ref. 1)
Implementation activities
416 trees around the city were given new growing beds. (Ref. 1, 2)
The green ‘wedge’ between Brunnsviken and Nybroviken bays was strengthened. (Ref. 1, 2)
