Previous derelict area

Weaver Square Community Garden started in May 2011 on a derelict site owned by Dublin City Council. The site contains the Community Garden and 28 individual allotments let out by the council. The main focus of the Community Garden is to create a safe and relaxing green space for all to use and enjoy. The organizers hope in the future to have more emphasis on the garden as a learning experience, with open days & workshops and other related talks.

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.

The company running the Zabalgarbi waste disposal site manages a solid waste–to-energy plant and also houses a mechanical biological treatment (MBT) plant, a composting plant, a landfill and a leachate treatment plant. During construction of the first plant, Zabalgarbi regenerated and recovered the entire Artigas-Arraiz area covering 108 hectares. The area was degraded by shaft mining activity and an opencast quarry. The project aimed at the reforestation and landslide mitigation of this degraded area. Today the area has been reforested, trails were built and space provided for people to enjoy themselves in gardens, picnic areas and along forest tracks. (Ref 1)

Zorrotzaurre is an artificial peninsula located within the Deusto district of Bilbao, Spain.

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 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.

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).

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 aims to manage vacant space and increase access to the green space in this city district [1].

Southsea Green community garden was developed from a derelict strip of land, to encourage more local growing and spread the message about gardening and volunteering. With time, the garden has transformed into a community green-space (1). Southsea Greenhouse is a collective of gardeners and crafters. The Greenhouse Community Co-operative is transforming wasteland into a community garden and re-investing profits from sales of produce and crafts, back into the local community. Community events and workshops are offered to encourage sharing of local skills and resources, foster a love of the city’s greenspace, and care for wildlife. (3)

The first one was in 1987 when the land was bought by the municipality and made into the park (Ref 2 and 3). The second one was in 2012 by covering a green space around the powder factory (Ref 5).
