Increase green urban nature for carbon storage (wetlands, tree cover)

The planting of trees and shrubs in Dolnozemská Street is part of the Bratislava zelenaj project and Bratislava’s gradual implementation of NBS to mitigate the negative impacts of climate change on its inhabitants. (1, 3, 9)

The intervention was planned to revitalize and clean a derelict area close to the university hospital in Blato. Before the project was implemented, the area was an informal waste disposal site for the locals. The area was neglected for more than 30 years. Initially, Mayor Milan Bandić planned a large urban park with a thermal spa in the spot. The area was cleaned and some of the constructions had begun, but later it stopped due to some political hurdles (Ref 1, 2).
The first phase, cleaning the shrubs and waste from the area has been completed in 2015, but the use of the area has not been determined yet, therefore the project has not been completed (Ref 1).

The curtain forest at the end of the city is a project that was initiated by the Timisoara's Municipality in 2001 by planting different tree species and creating a barrier for high-temperature summers. It's 60 m high and it was designed to stand in front of very strong winds especially since Timisoara is a city located in a very plain area. Now, it comprises 23 hectares and the municipality aims at 50. (2)

Sofielund invests in a sustainable area. Carpool/joint recycling centre were some of the proposals discussed when property owners, Malmö city and some experts discussed how Sofielund could become more sustainable in the future. The idea is that the environmental days in Malmö (e.g. a workshop) will lead to an action plan to make Sofielund greener. Property owners Sofielund has been at the forefront of a local sustainability work that can be a model for the rest of the country. In February 2017, a memorandum of understanding was signed about concrete efforts to strengthen the Sofielund area (Ref. 1, 2). There is a strong political support for the work that is being done in Sofielund and the BID concept is now upscaled to a sixth project area called Case Sofielund. (Ref. 6).

The city of Malmö works for a sustainable urban environment, e.g. through planning the city's new construction, working on existing buildings and at the same time striving to reduce the environmental impact. Västra Hamnen (Western harbour) is a new and ultra-modern district in Malmö. It is located on a former shipyard area right beside the sea, only less than a kilometer north-west of the medieval old town of Malmö (ref. 10). In the Western Harbour where land was available after the shipyard’s closure, high sustainability has been sought from the beginning. In dialogue with builders and other actors, Malmö City has developed guidelines for energy use, green structure, waste solutions and a healthy indoor environment. (Ref. 1)

The Urban Ecology Agency of Oslo (Bymiljøetaten) installed two CityTrees in the city of Oslo to act as green lungs in the city and reduce air pollution. The two CityTrees were placed at the Solli plass by Sommerrogata and on Nordraaks plass, close to Slottsparken. The CityTree is an environmentally-friendly plant wall with benches. (Ref. 2) It is an invention of a German company, Green City Solutions, and acts both as an aesthetically attractive furniture for resting, while simultaneously combating air pollution in city centres. (Ref. 1)

Revitalization of Rakova Jelša includes cleaning of the informal waste area and renovating it in a park which connects the city with the Marsh Landscape Park. In two phases, the park area was arranged together with the children's playground and the footbridge over Lahov graben. The possibility of regulated urban self-sufficient agriculture or gardens in the immediate vicinity of the city center means the added value of this area. (1)

FutureBuilt is a program running between 2010-2020, with expectations to continue from 2021-2030 (Ref. 9). One of its projects consists of the construction of a large greenhouse in between a housing complex in an old industrial building. The greenhouse will be the centre of the building and provide a Mediterranean climate with a lot of green facades, green roofs and indoor vertical greeneries (Ref. 1). The nave of the complex will become a greenhouse and the natural gathering point for the residents. (Ref. 1, 3)

This underground garage in Alicante, Spain, received a green roof makeover according to Alicante's climatological conditions (Ref. 2). Urbanarbolismo, a Spanish firm with a strong focus on vegetation, designed and installed this succulent garden in the courtyard of the garage. The garden is very low-maintenance and doesn't require any irrigation whatsoever. Further, with every passing year, it will grow more and more beautiful as the plants grow larger and take root. The Urbanarbolismo Benisaudet IVVSA parking garage was created by this Spanish design firm with the purpose of "keep[ing] the underground lot cooler, as well as improv[ing] its air quality." (Ref. 1)

With the "Green River" for Milan, the design team coordinated by Stefano Boeri has proposed an urban reforestation project that aims to realise on 90% of the seven abandoned railways a continuous system of parks, woods, oases, orchards and gardens for public use, linked between them by green corridors and bicycles made on the railroad tracks.
