City Garden
The city garden was a 2000 square meter large communal garden in Nuremberg Eberhardshof district that invites all citizens to take part in gardening and co-operating activities without any costs attached. The project was aimed at promoting sustainability for Nuremberg and the Bavarian region (1). The gardeners try to rely on a variety of different plants, even in their last season, they planted 35 tomatoes, 14 chili, ten potato, and twelve bean varieties alone. In 2013, a bee colony was also established. (7) The project had its last season in 2018, after which it had to be closed because of plans to create a district park in its area. (5) The city garden has established itself as an important leisure facility in Eberhardshof by offering, for example, cooking courses and training courses on tree pruning as well as numerous other topics.

Garden of Salitre
The Salitre Garden was a public park inaugurated in 1994 and built around the area of the former gunpowder factory. For this reason, it is also known as the Garden of Gunpowder (Ref 2). It is a green space planned in the urban centre, that has gone through different rehabilitation and remodelling stages. The first one was in 1987 when the land was bought by the municipality and made into the park (Ref 2 and 3). The second one was in 2012 by covering a green space around the powder factory (Ref 5). Another one was the inclusion of a new green labyrinth was installed in 2017 (Ref 4). The last one was in 2020 when a new botanical garden will be created on the island, with an open-air gym and a children's area (Ref 8).
Malecon Botanical Garden Recovery
There have been different activities throughout the time to recover and improve the Malecon Botanical Garden. In 2012, the main activity was to recover the Malecon Botanical Garden by introducing a collection of Mediterranean species and of other ethnobotanicals plants and delivering some other environmental services to the location (Ref 1). In 2019, there were different works to rehabilitate the Garden for the September Fair, and also some other plans to create a cultural and artistic space within the Garden (Ref 10 and 11).
The project has completed its first stage, but there is an ongoing number of initiatives to rehabilitate and improve the garden (Ref 9 and 10).
Regarding the status of the project, the first stage has been completed, but an ongoing initiative to rehabilitate and improve the garden is taking place (Ref 9 and 10).

Forest of Bere (Portsdown Hill) Green Infrastructure
Forest of Bere has been identified as one of the key project areas of the Partnership for Urban South Hampshire (PUSH) Green Infrastructure Strategy. The goal is to allow urban populations of south Hampshire to have better access to quality green space. (1) Part of the forest, called Portsdown Hill, is a Site of Special Scientific Interest (SSSI) is on the boundary of urban Portsmouth and supports extensive areas of calcareous grassland where a wide diversity of typical chalk grassland plants and insects can be found. The last twenty years have seen extensive areas of scrub being removed and restored to open grassland. The project aims to restore the once flourishing natural habitat of the forest while providing more recreational opportunities to the growing number of residents in the surrounding areas, was well as improving the ecological connectivity of separate woodlands (1,2,4,5).
Havant Thicket Reservoir
Portsmouth and its surrounding areas are under ‘serious water stress’ and water companies are being asked to take less water from some of their sources. This includes reductions to the amount of water that Southern Water can take from the rivers Test and Itchen in Hampshire. To address this, Portsmouth Water started the planning of a new Havant Thicket Reservoir.
The water to be stored in the reservoir will be supplied from surplus winter yield from the Havant & Bedhampton Springs. In winter, higher rainfall leads to a higher springs yield which flows into the sea, but a portion would now be pumped to the new reservoir. Long-term benefits of the proposed reservoir include enhancing the local environment and providing a new wetland habitat. (1,5)
In November 2020, the Havant Thicket Reservoir planning applications have been submitted to Havant Borough Council and East Hampshire District Council for validation. (7)

Constructed Wetland
Wetlands provide a varying degree of treatment of discharged water and are ideally suited for the containment and treatment of polluted water runoff, being a holistic example of Sustainable Drainage Systems (SuDS). The Dublin Local Authority installed an Integrated Constructed Wetland to treat polluted water discharged from the urban area, with the aim of cleaning urban runoff and drainage water. It was meant to purify water that discharges into a pond, and later on into the Tolka river. The project has been very successful in treating polluted water effectively, according to studies. (Ref. 1; Ref. 3)
Arrenberg climate district: Arrenbergfarm
Based on an urban regeneration project in the city district of Arrenberg, an association called “Awakening of the Arrenberg” formed in 2008, consisting of citizens, entrepreneurs and real estate owners seeking to transform their district. Under the umbrella of the project “climate quarter Arrenberg” initiated in 2014, whose goal is to make the district CO2 neutral by 2030, the development of a city farm covering 60,000 sqm on former railway premises - a Europe-wide unique project in urban farming – is one of their most important plans that make up their vision of becoming carbon neutral. (Ref. 1, 2 and 3). The goal of the farm is to produce healthy and locally produced food, while creating employment opportunities and remaining carbon-neutral, using power only from the sustainable power plant that will be installed for the project. (Ref. 2) In February 2020, the implementation has not yet started, but the “Awakening of the Arrenberg” association says the vision of the urban farm is stronger than ever before and that the project has received funding approval, with experts now working on feasibility studies. (Ref. 8).
Blue-Green Infrastructure in Neighborhood
The project aims to completely redevelop ‘Rozemaai’, a neighborhood in Antwerp, focusing on climate change adaptation, green spaces, and recreation. This includes a sustainable drainage system in which storm water flows via swales into a water stream with nature-friendly river banks, trees and bushes in the neighborhood, green parking lots, allotments and recreational facilities such as picnic tables (Ref. 1, 2, 3, 4, 5). Since 2019, the district has had a new, accessible park in which the Donkse brook plays a leading role (Ref. 7).
Nature conservation area Eskesberg on former landfill
From 1850 to 1956 the area Eskesberg was a limestone mine, after that up until 1972 it served as a landfill. When taken over by the city of Wuppertal, groundwater contamination and outgassing required a large remediation to remove toxic substances and recover the area according to nature conservation guidelines. (Ref. 8) Since 2005, it has been turned into a nature conservation area covering 8.5 ha where several rare plants and animals have resettled and thus the area also serves as an important recreational space for residents (Ref. 1, 2, and 3). The project was initiated by the local government, who also collaborate with different partners for maintaining the nature conservation area, such as the biological station, which organizes excursions, performs monitoring on the terrain and sets up bee hives. Also, residents apart from visiting the area can actively participate in its maintenance as volunteers, guided by the city of Wuppertal and the NGO Biologische Station Mittlere Wupper. Furthermore, the nature conservation association of Wuppertal and scientists from the university of Cologne are involved in the intervention by conducting research on the terrain (Ref. 1, 2, 3 and 6).
Green Roof on Theatre
On 'De Roma', an old cinema that has been renovated into a theatre, a green roof of 650m2 was created which improves biodiversity and contributes to Antwerp's climate change adaptation (Ref. 1, 4). A bee house was also later installed on the roof (Ref. 2). The green roof is created by volunteers of De Roma and Kopspel, which is an organization that provides learning-working places for student of 'Deeltijds beroepssecundair onderwijs (Part-time Secondary Professional Education) and temporary employment for people that want to turn back to the labour market (Ref. 1).
