Water management (SDG 6)

Liko-Noe is a business office building that meets all of its energy demands on its own and has a sophisticated system of water reuse and management. The building features a green roof, a green facade, and water storage ponds on the outside (Ref. 1). The building has a constructed treatment wetland for the wastewater treatment, uses solar energy for photovoltaic panels as well as thermal wall (Ref. 4). The aim of the project is to demonstrate that nature-based building techniques can significantly help address the challenges of soil and water degradation, and climate change (Ref. 1).

The Seven Lochs Wetland Park is an urban park that is due to be created in Scotland. It will comprise nearly 20 km² of land and water between Glasgow and Coatbridge. The park will combine many existing features, including four local nature reserves; Bishop Loch, Cardowan Moss, Commonhead Moss (a raised bog) and Hogganfield Park; Drumpellier Country Park which includes Woodend Loch SSSI and Lochend Loch; Frankfield Loch; Johnston Loch; Garnqueen Loch; Provan Hall a 15th-century category A listed building. It will be Scotland's largest urban heritage and nature park. The vision for the Seven Lochs Wetland Park is of a new park of national significance, sustaining and enhancing a high quality, innovative wetland environment that will (a) protect and enhance biodiversity and heritage (b) promote health and well-being (c) contribute to environmental, economic and social regeneration (Ref 1).

The municipality initiated to realize a healthy and climate-proof 'city island' which includes a large variety of projects, including the City Island Park Tour, which is a cycling/walking tour around the island that includes multiple green-blue infrastructure elements along two canals. Together it can be recognized as a large city park (ref. 2, 6). The tour contains the sights of green banks, recreation possibilities, bridges and boulevard-ways, thereby promoting environmental quality, mobility and attractiveness of the area (ref. 6). A food park at Leeuwensteyn is envisioned for 2050 (ref. 7).

The University of Portsmouth Library extension project includes a green roof with sustainability features signed up to a Building Research Establishment Environmental Assessment Method (BREEAM) assessment. (3) The award-winning features include the rainwater collection system for flushing toilets and a sedum roof. (2)

Skainos is a community regeneration project developed by the Methodist Church in Ireland’s East Belfast Mission. The Skainos Project has created the Vertical Gardens where around 6,500 plants make up the vertical panels, with a height of 12.5 m. The panels are designed to change colour with the seasons and will attract wildlife. The plants condition the air, remove pollutants, and provide seasonal colour and vegetation. A variety of roof gardens harbour natural flora and fauna. Green Roof technology is used to help with water retention. (Ref 2, Ref 6, Ref 7)

The project started in 2013, when a group of private companies started a collaboration with the municipality of Bari to build a series of gardens on the top of households roofs in the city. With a total extension of 2000 sqm for the experiment, the main goal is to create a small micro-climate. The main advantages of this experiment is an improvement in the process of absorption of rain and to reduce energetic costs for heating. The green roofs are expected to play a role in facing the challenges posed by climate change. (Ref.1.)

The Humberhead Peatlands are the UK's largest lowland raised bog complex and are part of the Natura 2000 network. They are located East of Doncaster and include the Thorne Moors and the Hatfield Moors (both towns are part of the Doncaster Borough). Commercial peat extraction has changed the hydraulic balance of the area, which impacts the condition of the peatland. This project aims to restore the water balance and thereby the peatland that can help prevent flooding, which is a breeding ground for the European nightjar, while also creating local jobs. The Humberhead Peatlands LIFE+ project completed its delivery phase in June 2019. (Ref 2, 3)

In light of the LIFE P.A.R.C. project, the NBS here presented consisted in the restoration of the fluvial and ecological continuity of the Magra and Vara rivers in the Montemarcello-Magra Regional Natural Park. The intervention implemented the removal of artificial barriers blocking the water continuity currently affecting biodiversity conservation. In the meantime, several activities implemented focused on restoring the area along the stream with the creation of walking paths and the use of signs to spread environmental awareness about the key habitat provision services of the area (1).

The oasis is one of the favourite destinations especially by naturalist photographers of the region, thanks to the presence of numerous animal and plant species. The oasis covers an area of about 20 hectares, is part of a SIC and ZPS area of 40 hectares and its management has been entrusted to the Noale WWF Cave Oasis Committee. It used to be a clay extraction area that got abandoned for several years. It was restored to create a new wild habitat that the local government declared a protected area (1, 2 and 4).

The project was part of a series of development projects which addressed the water management issues of the city. (Reference 1) The rehabilitation of a lake in the Adyváros neighbourhood included the renewal of the water reservoir, surrounding green areas, footpaths, and vegetation, as well as the installation of a new street light system, benches, trash cans, and unique street installations such as an interactive message board. (Reference 2) The interventions transformed the lake and its surroundings into a popular recreational area, frequented by locals. Since the completion of the project in 2014, there have been minor developments to the lake and its area, such as the renovation of the playground. (Reference 4) Apart from Adyváros, several other lakes were rehabilitated in several neighbourhoods (Adyváros, Győr-Szabadhegy, Marcalváros). (Reference 6)
