Environmental quality

This NBS is part of a national campaign that was first implemented in 1936 and it deals with an entire month through which local authorities alongside public institutions proceed at plant a large number of trees. The action was resumed in 2008. The Forest Month, how it was named initially, has been over time an opportunity to raise public awareness of the importance of forests, and their essential role in maintaining ecological balance. The current name - Planting month Tree- is regulated by the Romanian Forest Code. (1)

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).

Four hackberry trees were planted in the courtyard of the social center "La Grande Bastide". Children were involved with the support of the association "Aux Actes Citoyens" (in english"Act Citizens"). The planting of the 4 trees by the children was done with the support of animators/leaders (who work at the Social Center and animate diverse activities at the center), Karine Lurcin, president of the association "Aux Acts Citizens" as well as several members of the association. (Ref. 1). The Social Center of the "Grande Bastide"(non-governmental organization) was behind the idea, stating that: "It is the idea of ​​the center to have the children do the planting. We will surely be inspired by it for future actions", and, "from today, [the children] will always associate the earth with a particular and positive emotion: pleasure" (Ref. 1).

In 2013, St Davids shopping centre, which has over 200 stores and restaurants (ref 5) completed the installation of a green roof, which included bird boxes and beehives and the centre is looking to expand its green roof further. The city shopping centre has become the home of a 60,000-strong colony of bees. A second green roof was developed in 2015 in the parking garage to expand educational programs (ref 4). School children from Cardiff were involved in the planting of seedlings to create pollinator habitats for bees, butterflies and other local wildlife around the ‘Hayes’ area (ref 3). The customers and local community, with the help of this project, have been taught about the value of adopting an eco-friendly approach to public space. (ref 1)

The project involves the BBC Drama Village - a combination of studios and stores with associated offices and technical suites. It was the requirement for all buildings to achieve a BREEAM Excellent standard (ref 1). GreenBlue Urban structural RootCell systems were used for this development to create adequate tree root volumes, to ensure optimum tree establishment and growth in a demanding coastal location (ref 2). A Living Wall has been made which has a number of functions including the provision of a new home for solitary bees, lacewings and other invertebrates. A rainwater harvesting system has been installed (ref 1). Speaking generally, the studio, stores and office amounted to over 18,000 square meters and 900 new meters of HV, gas water drainage and telecoms (ref 1). Areas of eco-design include transportation, energy efficiency, water efficiency, materials, indoor environmental quality, waste reduction and biodiversity (ref 1).

In the new district ‘Kop Zuidas’, water green strip is created along the sidewalk in which stormwater is temporarily stored by means of high-grade vegetation and a drainage system. The stormwater slowly infiltrates into the soil and only reaches the sewage system in case of extremely heavy rainfall. It is a pilot project for stormwater retention and will be upscaled throughout Amsterdam when successful. (1,2)

Belfast is located within the River Lagan Catchment and is at risk from flash floods caused by storm water unable to drain away into the combined storm and sewerage network. The Local Development Plan will facilitate the development of green infrastructure resource or ecosystem services such as the green wedges in Lagan Valley Regional Park (ref 2). Lagan Canal is one of the emerging partnership projects to produce plans to restore and revitalise the Lagan Canal corridor. The river Lagan and the canal is an asset for the city, and for the wider region (Ref 1).

As an open root space, climbing plants usually only need a small floor area. Such planting areas can be cut out in a semicircular shape
directly on the facade, for example in the eaves strip of the roof overhangs (irrigation may be necessary). The city department for urban development initiated a funding programme for green facades and walls on private property in the city district of Wolbeck. It formed part of the proposed measures of the urban redevelopment programme for the district to improve its attractiveness and enhance green spaces. It included the reimbursement of up to 70 per cent of the arising material costs provided that the owner commits to maintaining the green façade for ten years. Although only three parties participated in the programme, public awareness of the multiple benefits of green space were raised (ref. 1, 2, 3 and 4).

The Hetton Lyons Primary School's green roof is designed to evolve and flourish over the coming years, helping to combat a number of climate change issues facing the next generation. Aims were ecological benefits, providing a natural habitat for plants and wildlife while helping to reduce air and noise pollution, cutting carbon emissions and assisting with rainwater retention and attenuation (Ref 1).

The project aimed to improve the Owler Beck riverbody catchment in Wakefield. Data collected by the Environment Agency revealed that the Owler Beck catchment is struggling to achieve the 'good ecological status' needed in order to meet the European Water Framework Directive. This is likely due to years of alterations that have removed the diversity of the environments and left the watercourse silty. The project aimed to address these issues by working on the priority sites along the river. A multi-phased scheme had been designed to relieve these pressures and deliver benefits for both people and wildlife across the catchment. (Ref. 1) The project is completed as of 2019 with 200m of river reach length covered in the catchment area. (Ref 7)
