Water management (SDG 6)

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).

The city of Salford has experienced several floods and is at risk of flooding once every 100 years (Ref1). The majority of properties in the city that lie in a high-risk flood zone are in the floodplain of the Irwell. The UK's Environment Agency and the council, designed a flood prevention scheme which included temporary water storage areas which will store floodwater on the existing Castle Irwell playing fields and public open space, and double as sports area otherwise (Ref 5). It aimed to have its own wetland and wildlife habitat, and will help protect hundreds of homes and businesses (Ref 4).

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)

The Environment Agency, Manchester City Council and the Irwell Rivers Trust had undertaken works to renaturalise a section of the River Medlock running through Manchester. The project had sought to return the river to its natural state by widening the channel and replacing the Victorian brick lining with gravel that provides a more natural-looking and fish-friendly section of the river and reduces flood risk at the same time (ref. 3). The project was also being seen as an EU exemplar of how to go about restoring an urban river (ref. 1, ref. 7).

The Revealing the Roch project uncovered two sections of the River Roch to expose a historic bridge which had been hidden for over 100 years (ref 1). Re-opening and deculverting the River Roch and bridge has a tangible benefit by reducing flood risk for the town (ref 4). The scheme, which is a key part of Rochdale town centre’s ongoing regeneration programme will help reduce flood risk in the town center and create educational opportunities. The project also includes enhancing the natural heritage of the river by introducing features that encourage river vegetation and creatures to re-establish themselves (ref 5). The project has since led to a wildlife boost, with brown trout, bullhead fish, heron and kingfishers all being seen since construction work to open the river began. (Ref 3). As the River Roch connects to River Mersey which empties into the North Atlantic ocean, this intervention addresses marine ecosystem restoration as well.

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)

New Bolton Woods Ltd is a development partnership between the regeneration company Urbo and Bradford Council (ref5). This project aims to create a new sustainable urban neighbourhood, linked to the existing Bolton Woods. As the majority of the proposed development is situated on land which falls within Flood Zone, a range of measures including the raising of ground floor levels, and incorporation of sustainable drainage techniques will be used to manage runoff.
The project intends to provide a series of well landscaped, high-quality open areas and parks for the community. There is potential for a long term phased canal restoration (ref. 1). The second stage,145 houses are currently under construction on the slopes off Poplars Park Avenue, overlooking Canal Road, and are due to be completed by 2021 (ref 6). West Yorkshire Ecological Service raised concerns that the development would lead to a loss of woodland (ref 6).

Coal mining in the Dearne Valley damaged the Dearne Valley landscape. To address these problems the Dearne Valley Green Heart partnership was formed in 2006, but the intervention discussed here is specifically related to the developments between 2012 and 2015, when it was founded as a Nature Improvement Area. It is part of the South Yorkshire Delivery Programme and part of the Doncaster Council as also being part of the Doncaster Green Infrastructure Strategy (Ref 1, 2).

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)
