Cheonggyecheon Stream Restoration Project
The Cheonggyecheon Stream Restoration Project saw the dismantling and removal of an elevated freeway and the uncovering of a 5.84km section of the Cheonggyecheon historic stream in the centre of Seoul, South Korea (Ref. 2). One of the world’s largest and most densely populated cities, the revitalisation of the Cheonggyecheon Stream has provided Seoul with an ecologically sensitive green pedestrian corridor in an area that was previously recognised as being congested, overpopulated and polluted (Ref. 4). The restoration has provided environmental, social and economic benefits within its immediate proximity (Ref. 2). In addition to becoming a "vehicle for revitalisation, urban renewal and economic development", it has "also signified a shift in Korean planning priorities", with both city authorities and residents now placing an emphasis "on health, sustainability and social responsibility" (Ref. 4). It has further "become a template for planning intention and action across South Korea" (Ref. 4).
Integrated Protective Coastal Zone
A combination of green and grey coastal infrastructure is being developed off the coast of Semarang, Indonesia in response to the increased risk of coastal flooding as a result of sea-level rise (Ref. 1). Due to its geography as a coastal city, "Semarang deals with various physical challenges...such as tidal flooding, erosion, land subsidence and rising sea levels" (Ref. 1). Tidal flooding is becoming increasingly worse as a result of climate-induced sea-level rise and increasingly extreme weather events (Ref. 1 and 3). Coastal protection which was historically afforded by naturally occurring mangrove systems has been reduced as a result of the mangroves being largely lost to urbanisation, fish farming and other forms of agriculture (Ref. 2). One proposed sub-project of the Integrated Protective Coastal Zone, Coastal Balance Project 01: Coastal Balance Pilot in Genuk/Sayung, will focus on the northeast of Semarang. Using the 'Building with Nature' approach, it will leverage nature-based solutions through the deployment of green infrastructure, primarily focusing on mangrove restoration (Ref. 3). Mangrove restoration is hoped to stabilise the coastline, therein reducing erosion, encouraging sedimentation and increasing resilience against sea-level rise (Ref. 3).
The Forks and the Winter Waterfront
Winnipeg lies at the confluence of the Assiniboine and the Red River, a location known as 'The Forks', which is the cultural centre and meeting place of the city. "The winter use of the river went through an unprecedented change over the last 10 years, organized by a private company (The Forks North Portage Partnership), that began to operate the 'Red River Mutual Trail', the longest Guinness World Record-holding natural skating trails on the Red and Assiniboine rivers, offering opportunities for skating, curling, cycling, walking, and cross-country skiing, along with cultural events and unique, community-designed warming huts, a restaurant on ice, art exhibitions and other activities. The river trails also links otherwise distant neighborhoods, and functions as a transportation and commuting route with a variety of access and exit points during the city’s typically 4-5 months of winter climate." (Ref.1 p60)
Traditional cultivation practices in Xochimilco borough
The Xochimilco borough of Mexico City is a World Heritage and Globally Important Agricultural Heritage System wetland site, with significant cultural and ecological importance in food cultivation and water ecosystem (1). Due to the deterioration of the area and lack of top-down initiatives for the restoration and conservation of the area, a number of grassroots initiatives trying to revive the traditional chinampa cultivation and restore the natural state of the ecosystem function and its native species such as the Xochimilco axolotl through reinvigorating sustainable practices that produce quality food and foster water supply. This NBS introduces 3 such grassroot intiatives: (a) Cooperativa Chinampayolo (b) Restauración Ecológica y Desarrollo A.C. (REDES) with its EcoQuilitl producer-consumer network and (c) Umbral Axochiatl A.C. (local community organisation). (1)
The City of Science
The proposed masterplan for the "Città della Scienza" or the City of Science by Vincent Callebaut Architectures and Studio d'Architettura Briguglio Morales focuses on sustainability with history to propose a self-sufficient urban ecosystem in Italy. More than a spatial work of art, it encourages the promotion of sustainable design, low carbon transportation, renewable energies, automation technologies, and green building materials. Because of these features, the project has many examples of nature-based solutions (e.g.vertical gardens, green roofs/walls, orchards). Operating on the principle of living facades, the Città della Scienza revitalizes Rome's forgotten military district into a vibrant, regenerating living city. [1][3]
Stavros Niarchos Foundation Cultural Center (SNFCC)
The Stavros Niarchos Foundation Cultural Center (SNFCC) is a project finalised in 2016 and “handed over” through a public/private partnership scheme, from the foundation/donor to the Greek state. The site hosts the National Library of Greece and the Greek National Opera in a 170,000 sq m landscaped park. The SNFCC's objective is to restore Greece's image and become a global role model of environmental sustainability. The project is committed to a range of educational and cultural activities, which have been provided for free. It also claims flood-regulating functions, air quality improvement impacts and shade provision, among others. [1]
Park Museum Vrana
Initially the park was created in 1903 as a summer residence for the royal family and had a no-visitor’s policy. For over 40 years the park collected 821 trees, shrub and, grass species from all over the world on less than 100 ha. After the estate was given back to the successors of Tsar Boris III, they partially donated the park to Sofia municipality and in 2013 the park-museum ‘Vrana’ was opened for visitors. Due to its rare species, well-preserved wilderness and historical significance, the park enjoys great interest from tourists as well as scientists as a biodiversity hotspot. (Ref 1)
Enlargement of the Dona Casilda Park
The enlargement of the Dona Casilda park started in 2006 when Bilbao Ria 2000, a public limited company created in 1992 with the collaboration of the Public Administrations in order to lead the recovery and transformation of degraded areas of the Metropolitan Area of Bilbao, decided to invest in the renovation of the park. (Ref 2,4) The park was considered the main lung of the city, thus its enlargement (which is the presented NBS) was seen as necessary. (Ref 3) As such, the main road that traversed the park was removed and 30.000 sqm of land has been added. (Ref 2,7) The green area was broadened, by removing the road and enlarging the park. (Ref 2)
Tully Park
The biggest park to date for the new town of Cherrywood in South Dublin is being developed. Tully Park will be part of a major strategic development in the area which will contribute to the economic growth of the county through the development of a vibrant residential and economic community anchored around a town centre. The park will act as a recreational space, and the plan is to create a high profile, high quality and distinctive flagship park with a range of visitor attractions and diverse active and passive recreational facilities. Schedule of provision to be informed by the current Dún Laoghaire Rathdown Open Space Strategy and local needs at the planning application stage but may include e.g. flagship playground, local pitches, courts, tea-rooms, toilets, public art, litter bins, street furniture, interpretation. The development of Tully Park shall be appropriate to the tranquil character and setting of the cluster of national monuments at its centre. The mature trees in the vicinity of the Tully Church complex shall be retained in so far as possible. (ref 1, 3, 5)
Abandoibarra's Green Oasis
Abandoibarra is an area of the town of Bilbao, next to the Bilbao estuary, sizing 348,500 square meters. Abandoibarra has been the industrial zone of Bilbao, where shipyards and other companies related to the industrial sector were located. Building upon the 1997 master plan completed by Balmori Associates, Pelli Clarke Pelli Architects and Aguinaga y Asociados, the area has been reinvented as an international cultural district and tourist destination. Two-thirds of the 30-hectare site is dedicated to parks and open spaces, creating a public oasis and grounds for a suite of buildings by master architects (Ref 1,2).
