The largest rain gardens in Sweden (thus far) has been created in Göteborg (Kviberg park). Kviberg's multisport arena was completed in the summer of 2015 in the northeastern part of Göteborg. Around the facility, there are parking spaces with a capacity for 500 cars. In order to handle the rainwater flowing from the parking area, approximately five per cent of the total area has been used for rain gardens, which both clean and store the rainwater. (Ref. 1, 2)

The project LIFE SeResto (LIFE12 NAT/IT/000331) aimed to trigger a process of aquatic recolonisation in “Northern Lagoon of Venice”, mainly through the transplantation of "Zostera marina" and "Zostera noltei" to small sites distributed throughout the area. The proposed intervention technique involved transplanting a small number of plants, with advantages in terms of lower costs and impact on the donor sites (1).

Bjerkedalen is a recently constructed park around the Hovin creek in Bjerke District. It is situated in the middle of a settlement block, which used to have few public spaces. The park now acts as a recreational area with lots of green space, a river and several facilities for outdoor activities. The construction of Bjerkedalen park incorporated the installment of several important blue-green structures and features such as planting native trees and plants along the river, providing open grassy areas as well as reopening the Hovin river from underground pipes, with the aim of improved water quality and flood prevention.(Ref. 2)

Rehabilitation project of the Ranillas stream and its surrounding area, as part of the larger city project to rehabilitate the waterways connected to the Guadalquivir River. The project included transforming the covered canal into a green corridor connecting the Tamarguillo Park with the Infanta Elena Park. It sought to build pedestrian walkways, leisure spaces, lengthen the bike lanes, increase tree cover, and restructure the covering of the canal. (Ref 1-6)

In 2010, about 300 people participated in the planting program for the “350” project and under the “Verde por el Clima” program (Green for the climate) organized by the Department of Environment, Cordoba city council (Concejalía de Medio Ambiente). (Ref. 3)

The ReLambro project is based on a metropolitan view where nature becomes an occasion for regeneration of the city: the river is no longer an empty and abandoned space but draws a great ecological and environmental system. The interventions, during the design phase, provide for the restoration of the naturalness of large sprawling areas, the reinforcement of the hedges and rows and channels system, the reorganisation of public and fruiting functions in areas at risk of flooding. The project strengthens ecological function by integrating it with urban functions (2).

Fornebu used to be Norway’s main airport, but was abandoned in 1998. The Fornebu project aimed to restore the 340 ha site in order to provide a sustainable, multi-use built environment with sustainable drainage systems and other green infrastructure in focus. The site now consists of residential and industrial buildings with a focus on green space and natural storm water management, involving the use of open and natural water retention methods, including swales, filter strips, permeable surfaces, detention basins and retention ponds (Ref. 1).

The Sotos de la Albolafia Natural Reserve is situated on a section along the Guadalquivir River, that runs from the Roman Bridge to the San Rafael Bridge (Ref. 3,14). It was declared Natural Monument in 2001 and is part of the Network of Protected Natural Areas of Andalusia (RENPA) due to its wide variety of birds (Ref. 5,15). "The declaration recognized the environmental value of the Sotos de la Albolafia, a singular natural enclave located in the urban center of a large city, in a monumental and historical environment also unique and with an unparalleled concentration in protected species, especially water birds and wetlands." (Ref. 3)

“The Royal National City Park, the world’s first national city park, was created in 1995 by the decision of the Swedish Parliament. The Park was established to safeguard and enhance the unique qualities of this area, containing outstanding natural qualities and heritage sites, ecologically important for the metropolitan area, and situated near and easily accessible from the central parts of Stockholm.” (Ref. 1)
One can experience a truly unique historical landscape, intertwined with parks, beautiful buildings, forests, open fields and beaches. In 2020, the park celebrates its 25 the year. (Ref. 12)

Pilestredet Park project was one of the largest urban ecology projects in Scandinavia and included redevelopment of a neglected inner-city quarter of Oslo while meeting high standards of sustainable construction. The project included energy efficient buildings with high quality indoor environments, plenty of green areas, as well as an extensive stormwater runoff management system for the whole site. Pilestredet Park also contributed toward the development of more sustainable construction techniques and products, much thanks to the strict requirements from the Environmental follow-up program developed by Statsbygg and Oslo Municipality's (Ref. 1)
