Joint implementation (e.g. tree planting)

Due to the challenges caused by climate change, Hamburg decided to become greener and developed a comprehensive, pioneering green roof strategy. The strategy aims at creating 100 hectares of new green walls by 2019 by providing grants for building owners for greening roofs and offering them rain water fee reduction owing to the rain water retention of the green roofs. (Reference 1) The financial support offered until the end of 2019 is 3 million EUR. (Reference 2) The services offered by the city in this plan consist of four pillars: promotion (financial incentive), dialogue, regulation, and scientific support. (Reference 7)

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).

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).

An environmental improvement programme has helped to clean up a previously derelict plot of land on one of Belfast’s main thoroughfares, by transforming it into a community garden. A vegetable garden was officially launched in July 2009 at Walkway Community Association, on Finvoy Street in east Belfast. The scheme is part of Belfast City Council’s ongoing £150 million Investment Programme of work across the city. (Ref 1, Ref 5)

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)

Arcosur is a new residential neighbourhood project approved for construction in 2008 after the hosting of the Zaragoza Expo 2008. In its structure, it seeks to develop a space of 4 500 000 m2 into around 21 000 new homes, and out of which around 1 500 000 m2 will be squares, parks, and other green spaces. These green spaces would connect the neighbourhood and ensure all residents have access to green areas. (Ref. 1)

The Carbon Landscape is a pioneering project in landscape restoration in Wigan, Warrington and Salford. Led by the Lancashire Wildlife Trust, it will revitalize a landscape left devastated by decades of coal-mining and peat extraction (Ref 5). It works to restore key habitats and reconnect local people with their unique natural heritage, preserving it for future generations. The restoration of the peat base to lowland raised bog provided an opportunity for carbon sequestration and storage (Ref 1). There is a strong vision to reconnect local people with their rich natural heritage, creating opportunities and a sense of pride in the local area (Ref 4).

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).

Within the national park of Alta Murgia, a project was implemented since 2006 from a company which produces ecological products ("Fattoria della Mandorla"). They aimed at creating an ecovillage with allotment gardens by practising biological agriculture and promoting biodiversity for cultivated plants. In addition, the project aims at improving the contact of visitors with nature and give further value to the natural park. Moreover, the project wants to stimulate sustainable production and consumption of cultivated products. (Ref.1.)

The Garden Factory ('Tuinfabriek') is an exceptional urban agriculture project on a roof of the central station that aims at becoming the largest food-producing roof of the Netherlands. The project is a self-sustaining vegetable garden located on the roof of a busy mall in the centre of Utrecht (ref. 5). On the roof, citizens, students, company employees and schools work together to grow vegetables and keep bees and chicken. The Garden Factory reflects an ecological 'self-sustaining factory' as the chickens, worms and bees 'work' in the garden as being part of the decomposing system and pollination and a system is built for rainwater retention that allows for irrigation (ref. 1). Eating, composting, sowing, growing, harvesting, cooking form the production process of this Garden Factory (ref. 4).
The main elements of the roof garden are in place, such as the crop bins, the chicken coop and the decomposing machine are completed. However, it is an ongoing developing project as some elements are still in development stage such as some elements of the Soup Kitchen and the aim is to integrate the Garden Factory more with the central station shopping mall in multiple ways (ref. 1).
