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).

Zorrotzaurre is an artificial peninsula located within the Deusto district of Bilbao, Spain. It was formed during the 1950s and the 1960s, when a canal was built to facilitate navigation in the estuary of Bilbao. The Zorrotzaurre project is the latest major urban renewal project to commence in Bilbao. It is an integral and sustainable plan that recuperates a currently derelict site to convert it into a new quarter, and which also includes a flood protection system with water tanks to retain water and a flood protection barrier (Ref 1)

The re-urbanization of the Poligono de Levante neighbourhood included the creation of two large urban parks to form a green area of 47 722 m2 and several environmental considerations such as a bridge for fauna (Ref 1), as it is a strategical zone of Palma . It is a combination of different initiatives, some of which include green elements (Ref 1 and Ref 3).

The government of Mallorca promotes orchards, as part of an ecological movement in Spain. As a result, five orchards were constructed, reclaiming abandoned urban spaces by the Mallorca city government in 2010.
The project has three pillars: strengthening social cohesion and inclusion, creating opportunities for education and for recreation. They were also constructed with pensioners in mind (Ref 2).
There would be an annual draw to give to distribute the orchards. However, this got delayed since 2013. In 2019, the municipality took back the property from the previous owners, and one of the orchards was taken from the list of orchards due to its bad conditions (Ref 5). In 2020, there was going to be a new draw for the distribution of orchards with new focus groups requirements but due to Covid19, this project has been paused (Ref 5).

The Urban Forest project represents an increase of urban trees in the city. There will be two phases of this project. In the first, it consists of a transformation of an eye-sore and abandoned space, around previous Canodrome, into a large urban forest (Ref 1, 9). The second one will be located in the land of the velodrome of Es Tirador. This projec has been delaid due to unforeseen costs (Ref 10).

GIFT-T (Green Infrastructure For Tomorrow - Together!) is a four-year European project of which Medway was one of five case studies. In this project communities, businesses and governments were brought together to facilitate bottom up planning and implementation of green infrastructure (Ref 1). The product of this is a general business plan, and the planned intervention of focus here is the "Thames Terrace Invertebrates - corridors for wildlife" (Ref 2). Hoo Island already has areas that serve well to sustain invertebra species, but as of yet also has underutilised potential in this respect. This intervention addresses the latter.

Following an extreme flood event on August 9th 2008 in Glendhu Park, eight houses experienced flooding and many more came within inches of being flooded. Two swales were constructed by Dublin City Council to provide surface water storage to ensure that no flooding will recur in a similar 100-year pluvial event. The swales are designed to self-drain back into the existing surface water sewer system following a severe storm event (Ref. 1).

Lodge Hill is a nature area allocated to become a settlement capable of delivering approximately 5000 dwellings by 2028 (original plans). Green infrastructure is a key component of the current plans and specific GI implementation will be based on the existing GI assets. Specifically, the plans include green corridors, sustainable urban drainage systems (SUDs), various parks and street greenery, community allotments, buffer zones around sites of special scientific importance (SSSIs) and woodland (Ref 1).
The plans for Lodge Hill have been controversial, as Chattenden Woods and Lodge Hill Site of Special Scientific Interest (SSSI) is a nationally important area of ancient woodland and rare grassland that supports one of the largest populations of nightingales in the UK (Ref. 7, 8, 9).
In 2018 Kent Wildlife Trust started a campaign (#SaveLodgeHill) to ask Medway Council to not to allocate Lodge Hill development, which has resulted in a scaled-back version of the original plans for Lodge Hill from the construction of 2,000 to 500 houses, avoiding any direct loss of the Site of Special Scientific Interest - which will still have an impact on the nightingale's population (Reg. 7).

The former Paulsgrove landfill is being developed into the Horsea Island Country Park to address the deficit of public open space for Portsmouth’s residents (3). The council plans to put in place a number of initiatives to make sure the country park is a recreational facility and attracts a diverse range of wildlife. This is being progressed through the PUSH Green Infrastructure Implementation Plan. (1). Veolia, the company that operated the landfill site on Horsea Island has the responsibility for implementing the landscape proposals which include tree planting, grass areas, wildflower meadows, footpaths and cycle routes.

Owing to the city’s participatory budget, the residents created a well-equipped green recreational square in a vacant area of one of Bydgoszcz's neighbourhoods. The initiative involved the creation of an outdoor gym with several exercise equipment stations, as well as planting pollution-resistant trees and bushes - including oaks, maples, pine and spruce. The initiative aims to manage vacant space and increase access to the green space in this city district [1].
