Sequester and store carbon

The municipality of Catania has promoted an initiative that involves schools and non-profit associations, for which available space for urban gardens and horticulture has been provided. The main aim was to regenerate areas which were used abusively as landfills and for criminal activities. What will be produced must strictly conform to the principles of sustainable production, by using biological products and 0 environmental impact techniques. (Ref.1.)

Birkenhead Park is one of the most important public parks in Britain. It is registered Grade I in English Heritage’s Register of Parks and Gardens of Special Historic Interest. In 2002 to 2007, funding was made available to restore the park, and now in 2017 a master plan aims to further “enhance and secure” the park. (Ref. 1, 2, 3). Birkenhead park is considered the first publicly funded park in the world, and not only holds the Grade I in English Heritage’s Register of Parks and Gardens of Special Historic Interest award but also the Green Flag award. (Ref 6, 7, 8)

The Natural Park of Collserola (about 8,000 ha) is a forested area in the hilly Northern fringes of Barcelona. Since 1987, Collserola has been managed under a special protection plan and forms part of the European FEDENATUR network that aims at protected fragile peri-urban ecosystem for both their social and ecological functions. The park is jointly managed by a consortium including the Catalan government (Generalitat de Catalunya), the Barcelona Provincial Council (Diputació de Barcelona), the Metropolitan Area of Barcelona (AMB) as well as all adjacent municipalities (Ref 1).

The FUTURE - a project of 100,000 trees in the Porto Metropolitan Area - is a planned and coordinated effort of various organizations and citizens to create and maintain native urban forests in this region, which needs to enrich its biodiversity, sequester carbon, improve quality of air, protect their soil and contribute to a better quality of life for regional people. The 100,000 Trees Project for the Porto Metropolitan Area” intends to restore 100 hectares of urban forest with native trees. (1, 2)

This NBS consists of a vertical green all installed inside one of Energias de Portugal's (ranks among Europe's major electricity operators, as well as being one of Portugal's largest business groups) centres in Porto. It was installed in 2011. The garden is located next to workplaces and customer service desks. The company wished for a garden with a natural and fresh appearance. Common plants used here were Peperomia rotundifolia, Peperomia obtusifolia, Rhipsalis cassuta, Philodendron scandens and different varieties of Chlorophytum comosum. (1)

The Oriental Park of the City of Porto is an urban natural park designed by the landscape architect Sidónio Pardal. It will be one of the largest urban parks in the country and the second-largest in the city of Porto. This NBS focused on the transformation of a derelict, depressed urban area into a green space. The first part of the park was inaugurated in July 2010 and the municipality has plans to build it through several phases over the next decade until it reaches its project area. (1)

The Deûle park is a periurban park in northern France, which was created to protect the irreplaceable capture fields of the south of the Lille conurbation. It is an important element of the Regional Green Trail and an important recreation area in a region that is particularly densely urbanized and poor in green spaces. The park is the winner of the " Landscape Award 2006" and the European Landscape Award from the Council of Europe in 2009 (Ref 2).

The Garden of (Re) Finds, was born in Lille in 1997. It is the first "community garden", directly inspired by the model of the gardens New York, which was created in France (Ref 1). There is an organic vegetable garden, a scented hill, a rainwater harvesting system, a regional hedge of regional species, a compost corner and a convivial shelter in corded wood and vegetal roof (Ref 2).

While Hamburg has already had an impressive green infrastructure, it is now (since 2013) implementing an interconnected green network that will cover the 40 % of its area and support commuting by bicycle, recreation and climate change resilience. The project is planned to be completed by 2034. (Reference 9) The project aims to connect the two green belts, parks, recreational areas, cemeteries and animal habitats to each other with green paths and with the already existing “green axes” leading from the agglomeration to the urban core. The green network could not only absorb more CO2 but also prevent flooding by soaking up an increased amount of rain- and seawater caused by storms. (Reference 1, 2). An extensive network of cycle paths is also being built as part of the project. (Reference 2)

The Newton and Arkwright roof, buildings of the Nottingham Trent University campus, holds one of the region’s largest sedum roofs, which spans its way 2,500m² across the building, creating a home for 13 varieties of sedum, insects, songbirds and a new colony of honey bees, creating a trio of hives over all campuses (ref. 1). A 150m2 bank surrounding the building is unmown in order to promote biodiversity and attract pollinating insects in the summer months. Green-walled gates was also part of the implementation activities of this project. (ref. 5).
