Environmental quality

With the relocation of the railways between the Hauptbahnhof and Pasing a large area became available for an infill development strategy. The redevelopment of central railway areas of Munich is in line with the city's guidelines for sustainable development (Perspective München) referred to as compact - urban - green. The initiative is aimed at implementing 7500 new flats and creating 15000 new workplaces in total, which are supported by green recreational areas. (Reference 1) The project consists of six separately planned parts, some are already partially finished. (Reference 2) This NBS discusses Birketweg, one of these parts, which is 60 hectares large.

Manchester’s Stevenson Square was given a green makeover. In addition to securing funds from Manchester City Council, the project underwent a substantial crowd fundraising campaign to transform the square into an ‘urban oasis’ and provide street trees, permeable pavements and planters.The pavement was extended on one side of Stevenson Square which enabled street trees to be planted. More tree planting undertook on the central reservation and a green roof was designed to collect and store rainwater. Self-irrigating hanging baskets were installed on lamp posts (ref 4).

Number One First Street is at the corner of Medlock Street and Whitworth Street behind the train arches near Oxford Road Station in the city center of Manchester (ref. 6). During the redevelopment of the former BT building now called Number One First Street a green roof was installed (ref 2). Whilst the vegetation slowly established, it provided a habitat for invertebrates and insects. A green wall, accommodating 37,000 plants was planned to be installed by 2020 which would replace glass, plastic and metal cladding with greenery (ref 1).

Wigan Flashes Project is encouraging natural re-colonisation to a site of very high conservation value and an enormous asset for recreation for the local community. The Wigan Flashes are a group of eight shallow wetlands, formed originally as a result of mining subsidence, which extend south from near Wigan's town centre. Over time, the industrial landscape has evolved in to a mixture of open water, reedbed, mossland, willow carr and fenland (ref 1).

Three London Plane trees were planted in a specially designed trench in Howard Street, Salford, Greater Manchester in 2015 with the aim of capturing the impact that trees had on both cleaning polluted water from road runoff and managing levels of surface water, which can lead to flooding when not properly managed (ref 1). This project in the City of Salford was created to study how trees can aid in the management of urban stormwater as a novel retrofitted street tree demonstration (ref 3). It was led by Manchester's City of Trees movement. (Ref 3)

Most of the open spaces around Munich are designated as green belt areas and are being used mostly for agricultural purposes. As a lead project of its green strategy, the city now aims to protect these areas and to upgrade their quality by cooperating with local farmers and promoting a shift to extensive and ecological farming, developing habitats, corridors as well as a network of cycle tracks and footpaths for recreation (Reference 3, 4). The city supports the farmers with advisory services, but also with the organization of the implementation of the ecological projects. The farmers are motivated to join by being able to use labels such as "Potatoes from the Greenbelt of Munich" on their products. (Reference 3) The initiative also includes herb gardens, provided by farmers and rented by citizens. (Reference 1) A further project included in the initiative is the "Münchner Ökokonto, a biodiversity offsetting principle by which the former low moor complex of the West of Munich is being renaturalized on 28 areas with a total area of 67 ha. (Reference 5)

The Connswater Community Greenway has created a 9km linear park project in East Belfast following the course of the Connswater, Knock and Loop Rivers, connecting the open and green spaces. As part of the project the Connswater River will be cleaned and brought back to life. The Greenway will create attractive, safe and accessible parkland for recreation and community activities. The project will improve the quality of life for the people of east Belfast as a whole new greener environment will emerge. (Ref1)

Connswater Community Greenway is a visionary urban regeneration project that is transforming East Belfast by combining improved flood protection with the creation of public spaces and pedestrian/ cycle routes that connect communities. (Ref 6)

City of Trees is an innovative movement set to re-invigorate Greater Manchester’s landscape by transforming underused woodland and planting a tree for every person who lives there (ref 1). Manchester City of Trees had undertaken work to improve water quality of a tributary of Worsley Brook through channel naturalisation and create wet woodland in the Cleavleys Nursery. The discharge from the tributary caused water quality failures in Worsley Brook under the Water Framework Directive (WFD) (Ref 3). This project allowed the stream to take a more natural course through the woodland and the waterlogged woods provide habitats to species and remedy these water quality issues (Ref 3).

The roof installation at the Re:center building comprises of a wildlife pond planted with native marginal plants, a native wildflower area, grasses and herbs, bird feeder tables, insect houses etc. Design features encourage the development of flora and fauna on the roofing area and a growing media (from ABG) provides a nutritionally rich base for vegetation. Beneath this surface, a free-draining void allows for storage of collected rainwater to irrigate the vegetation. This roof is part of the Bright Building at the University of Bradford. (ref2) The building was known throughout its building phase as The Sustainable Enterprise Centre, but it is recognised that thinking around sustainability has moved considerably since this project started back in 2007 and the new name will ‘re:flect’ new agendas in a way that is distinctive within Higher Education (ref 6).

In 2010 a new drainage system was installed in Traktoros Street that solved the disposal of surface-water so that bigger storms would not cause damages in the area and separates rainwater from the sewage. The rainwater is directed to the lake in Adyváros. The project was the third phase of the complex reconstruction of draining in the Szabadhegy neighbourhood. While the first two phases (the construction of the main pipelines and drainage of Pannónia Street; drainage of Vak Bottyán Street and paving streets) were financed by the municipality, the third phase was implemented with the help of the EU.
