Nature-based solution

Constructed Wetland
Dublin (FUA), Ireland
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)
Constructed wetland for Balili River
La Trinidad, Philippines
Balili River, situated in the province of Benguet, is among the many urban rivers in the Philippines that suffer from severe pollution due to various human activities. Indiscriminate dumping of waste in almost all of its 23 tributaries is a significant contributor to the pollution. Despite this, the river remains a critical source of irrigation for farmers in La Trinidad who primarily grow strawberry and salad crops in the valley. However, the use of contaminated water from the river poses a direct threat to the food safety of consumers of these crops. Moreover, during the summer, the black water of the Balili River is a constant eyesore in the community. To address these environmental concerns, a pilot study was conducted aimed at exploring treatment options for the polluted water in Balili River. The study focused on assessing the use of local plants to restore biodiversity, conserve wildlife habitats, and test the phytoremediation potential of local macrophytes. The pilot area was established within the Organic Farm of Benguet State University near the main stream of the Balili river. The study set up two types of constructed wetlands (CW), a surface flow CW for floating plants and a horizontal subsurface flow CW for emergent plants. The results of the pilot study suggest that constructed wetlands could be an effective solution for cleaning up the Balili River. The implementation of constructed wetlands in Balili River can not only improve the water quality but also benefit the local community and ecosystem. [1,2]
Conversion of the former military base into a garden town
Münster, Germany
After its abandonment by the British military in 2012, the development of a new utilization concept and plan for the former military base in Gremmendorf was encouraged by the city’s planning department. Intensive citizen participation efforts were identified and ideas conceptualized, followed by an architectural competition based on which the spatial development plan was elaborated. The plan, which is currently being developed further by the winning architecture bureaus in coordination with the spatial development authority, intends the development of an attractive living quarter as a "garden town" with several green and sustainable drainage elements (Ref. 1 and 5).
Coronmeuse Eco-district
Liège, Belgium
The Liège Expo 2017 Masterplan was developed for the city of Liège, as part of their bid to organize the International Expo of 2017. In this plan, the Expo was not just an exciting stand-alone event, but rather the start of a sustainable transformation and an ecofriendly future of the city. The proposed development on both banks of the River Maaswill aimed to create new access to the river and improve the quality of life and the sustainability of the city, all at the same time (Ref. 1). While Liege was not awarded the 2017 Expo, the decision was made by the City to continue the competitive dialogue procedure initiated with a view to developing the Coronmeuse site into an eco-district (Ref. 12). Construction was launched in 2020 (Ref. 14).
Covering the A7 highway
Hamburg, Germany
The aim of the project was to extend and cover one of Germany’s busiest highways, the south-north highway (A7). The highway had divided neighborhoods from each other and had had negative environmental effects like noise and air pollution. The new green roof will have three parts that connect the existing green surfaces to each other, these parts constitute the three phases of the construction. The urban areas in the vicinity of the noise-reduced motorway will be developed for residential construction. The project also includes the reconstruction of the Langenfelder Brücke in a way which makes the bridge wider, and also provides better noise protection for locals. (Reference 10) In September 2020, only the first phase has been completed, and the final completion is planned for 2028. (Reference 1, 3, 12).
Craigmillar Town Centre temporary greening
Edinburgh, United Kingdom
Craigmillar Town Centre Temporary Greening project transformed a vacant development site in Craigmillar which is reserved for a new high school, not scheduled to be built until late 2020, into a temporary green space. The site is at the centre of the wider Craigmillar regeneration area, adjacent to the newly-built Community Hub and neighbouring plots at varying stages of development. EDI's PARC Craigmillar Ltd is responsible for the regeneration in Craigmilar, working in partnership with Edinburgh & Lothians Greenspace Trust (ELGT) and the City of Edinburgh Council. The initiative will create a meanwhile space for community use, while works begin on the town centre development. The greening will allow the area to become an active space for the local community to enjoy and ease the construction process. Craigmillar Town Centre Temporary Greening forms part of a wider plan for the redevelopment of Craigmillar Town Centre. The masterplan, which was approved in December 2014, includes 330 homes, a retail centre, restaurant, community play area and high school – where the temporary greenspace will be situated until building commences.

Crayfish Action Sheffield Project
Sheffield, United Kingdom
Two of Sheffield's rivers, the Limb Brook and the Porter Brook, have been identified as having strong populations of native white-clawed crayfish. The native crayfish is under pressure from the alien, invasive American signal crayfish and the crayfish plague. If no action is taken, the white-clawed crayfish populations in Sheffield could become extinct in a few years. Crayfish Action Sheffield aims to maintain and increase Sheffield’s native crayfish populations through habitat enhancement, public education and creation of bio-secure 'Ark' sites. It is a collaborative research project and Sheffield Crayfish Working Group’s members are from a range of conservation organizations. (ref3) The First time Crayfish Action plan was implemented in 2008-14 and after it ended in 2014, again the issue was looked in 2017. (ref 5)
Creation of the Park of Asprela
Porto, Portugal
Parque Central da Asprela is being designed by a team of specialists who see the great challenge of hydrographic control of Ribeira da Asprela and all other surrounding streams as an opportunity to create a unique landscape space in Porto, pleasant not only for the enjoyment of population but also as a crossing solution (pedestrian or cycling) for the academic community that daily studies and works in this area of the city. The park is part of the green lung of the city. This NBS is a continuation of an action implemented in 2015 by the Municipality of Porto that had in mind the creation of a park which eventually had to be renovated and integrated and this is how this new NBS came to be implemented.

Creation of the Zabalburu Square
Bilbao, Spain
The Zabalburu square is a square located in the city of Bilbao at the confluence between the streets Autonomía and Hurtado de Amézaga . In 2008, the creation of the square, situated on one of the main roads leading into the city, enabled the recovery of almost 3,000 m2 for leisure and recreation space. It was designed as a forest that protects citizens from road traffic, and has 77 different sized trees that act as a plant barrier. This NBS was necessary since it is located in a quite crowded area (Ref 1)
