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)

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).

A project for the creation of a new central park was launched in 2018, where a harbor consisting of three docks used to be and is now used as primarily as a car park. The park was planned to consist of three large green spaces that are the exact same size as the original docks. As the green areas are planned to be surrounded by rows of trees, the park will look like New York’s Central Park. The park is set to contribute to Antwerp’s climate change resiliency as the central green area will contain a water basin in which stormwater can be stored temporarily and slowly infiltrate, which is enhanced by the riverbank vegetation (Ref. 1, 2, 6).

A green roof of the total area of 362 m2 was established in a modernized historic neighbourhood in the centre of Bydgoszcz. The rooftop serves aesthetic and recreational purposes for the residents and visitors. Selected plants retain as much as 40-99% of rainwater and absorb air pollution [1].

The NBS is a large green roof on top of "ATRIUM PARK", which is a modern neighbourhood of 4 buildings in Bydgoszcz. The spacious green park of 5,000 m2 is located on the roof of a multi-storey garage that extends under all buildings. It is divided into zones: a playground, an area for active recreation, and the relaxation area. The description of the project stresses its beneficial effects on the health and well-being of the residents [1].

Focus Park is a large shopping mall with green terraces (900 m2) and green walls in the city of Bydgoszcz. The project serves marketing purposes – the green areas outside the mall are visible from various vantage points. Due to the selection of pollution resistant plants and installation of an automatic irrigation system the project also involves water retention and supports local biodiversity and good air quality [1].

On an office building, one of the largest green walls of Belgium was created (50.000 plants) that improves air quality, reduces heat stress, and improves biodiversity. The green wall also isolates the building, resulting in less energy use (Ref. 1-3). The wall consists of a variety of native plants and is irrigated with water collected on the roof of the building (Ref. 1, 2).

A roof garden of about 370 square meters was built on the new building of the Diakonissenklinik in the course of the general renovation. The new intensive greening of the roof can be seen from many hospital wards and serves as an additional recreation facility for its patients (Ref. 1).

The ‘Mountain Forest Initiative’ was launched in 2009 by the Bavarian Ministry of Food, Agriculture and Forestry to restore the protective function of the vulnerable alpine forest in light of climate change, and was ongoing until 2014. To create a general sense of ownership in the process, the Mountain Forest Initiative sought the involvement of different stakeholders at the local level (e.g., private forest owners, land-use related authorities, hunters, nature conservationists, and tourism associations) (Ref. 1).

The acronym VERDIR stands for Sustainable Rehabilitation and Responsible Innovation (Valorisation de l’Environnement par la Réhabilitation Durable et l’Innovation Responsable) and is a project of the University of Liège, about the development of local economic activities based on urban and peri-urban agriculture. It aims to convert existing brownfield sites according to the needs of the population. This involves the large-scale production of vegetables and plants which can be used for food but also for the pharmaceutical industry and the production of biomass, which is increasingly needed (Ref. 1).
