Climate change mitigation

The 2,044 square meters green roof on Sharrow School in Sheffield is designed to reflect the different habitats surrounding the city and includes a wildflower meadow and grassland plants as well as a wetland area with a small pond. The aim of the green roof was to provide added value by assisting the control of stormwater, humidity, noise, heat and pollution. It has been declared as a Local Nature Reserve by Sheffield City Council with the support of Natural England, in recognition of the importance of the roof to wildlife and educating the school's pupils about nature and the environment.[1][2]

The creation of pocket parks is an urban initiative that has steadily grown throughout Budapest since 2010 (Reference 1). Most of these projects are citizen-led, but there is often support provided in the form of education and consultancy by initiatives such as the Contemporary Architecture Center (KÉK), or sometimes the local government (Reference 8). These spaces, typically covering an area of 1400 square meters only, are multi-functional and provide a space for small-scale food production, recreation, community sharing, and can be a fundamental element of neighbourhood rehabilitation. Moreover, it provides positive environmental effects such as water retention and the improvement of the area's micro-climate. Pocket-parks are critical in increasing the number of green areas in neighbourhoods that have limited space. (Reference 9)

The Porto Biospots Network is a partnership of the Municipality with "Infraestruturas de Portugal", and is a network of urban forest areas (predominantly autochthonous) that aims to allow the reforestation of adjacent transit routes, major highway nodes, and routes of circulation within the city, transforming environmentally poor lands into green areas that provide multiple ecological services. This initiative foresees the reforestation of 14 areas and the planting of 10,000 trees by 2021, having already completed 2 roads, with a total of 1305 native trees planted. The biospot is the materialization of a part of the Municipal Ecological Structure of Porto. [1][4]

The Gran Recorrido de Bilbao (GR), known as the Green Ring or Great Route of Bilbao, is a part of Bilbao’s Green Belt, a municipal initiative that encompasses forest and urban parks surrounding the city. The Green Route aims to skirt the City passing through the forest parks of Artxanda, the mountain of Avril, Arnotegi, Pagasarri, and Arraiz. It completes a route of 99.3 kilometers in a closed belt of trails, paths, roads and streets signposted with references to routes, interesting places, and general information. The Green Route is reachable from the center of Bilbao through eleven additional routes that all lead to a central point. [3][4]

After 2011, in the face of crisis and austerity hardship and the collapse of the central public welfare system, many municipalities assumed the role of enhancing food production through urban allotment gardens. In Ag. Dimitrios (AD), the idea emerged from a couple of newly elected representatives one of whom was part of an agriculture cooperative outside of Athens. A mixture of social and environmental goals were set (to change the microclimate, to change people's habits, to reintroduce contact with nature in the city, to be environment-friendly through good practices, and to create an educational ground for children).

A private investment project that aimed to create a new building complex in the Findorff district of Bremen and build two large residential buildings "Münchner Bogen" and "Findorffer Tor" with green roofs on top. The green roofing of the buildings was influenced by the local actors - the alliance "Green Bremen" and the advisory board of the Findorff Council. The initiative aimed to contribute to sustainable urban development by the positive impact on biodiversity, rainwater retention, improved local air quality and provision of natural thermoregulation for the buildings (Ref. 1, 2, 3).

Green roofs were created on vehicles in the Spanish cities of Barcelona, Girona, Córdoba, Valencia. This initiative is based on the project of Marc Grañén, who developed PhytoKinetic a project for the development of moving gardens. (ref 1) The city of Palma de Mallorca was also considering its introduction as a measure of sustainability. (ref 1) The intervention, however, remained in the pilot stage (ref 1 and 4).

The Sea's Corridor is a project that created green spaces with good quality that act as green belts of the city while serving as a support for the sustainable and not motorized means of transport. It was part of a project Plan called "Plan E" of the Municipality of Palma (Ref 1). The project was completed and in 2020 there are plans to do some renovations. They want to join the Sea's Corridor to Platja de Palma, as well as create new green spaces with a wider link with the ocean (Ref 5).

As part of World Tree day celebrated on March 21, 2017 the Sintra Service for Protection of the Nature and the Environment (SEPNA) as well as the Sintra Branch Segura School carried out several education workshops for school children to inform about the importance of tress for our natural environment and carried out afforestation and reforestation actions inside the green spaces of Sintra.

As part of a larger project, this project aimed at creating a vertical garden in the Levante Square, in the Deustro neighborhood, the city of Bilbao. The intervention was initiated by the Bilbao's municipality in 2016 and aimed at creating a green area that was a bit unconventional and artistic at the same time. The landscape design incorporates local elements such as the trawlers, the cliffs of the Cantabrian coast and the local architecture, integrating nature and tradition (Ref 1).
