Vacant space model

The project aims at realizing a large urban park to link the city and the sea coast. It is a project of significant social value, as it takes place in a neighbourhood which has been in a state of decay for 50 years. The intervention includes new facilities for recreation and sport, but first of all new plantations and the creation of rooftop gardens. It would be the second-largest park of the city, by linking the city and the sea. (Ref.1.)

This pilot project to create social gardens in Gdynia was developed by a cooperative of the local government, NGO sector and businesses. The project involved creating 3 (and finally 6) social gardens in different locations of Gdynia (Oksywie, Grabówek and Redłowo). They serve ecologic (greenery planting), horticultural (jointly managed vegetable and herb gardens), social (community integration) and educational (workshops on topics such as healthy lifestyle or building bird boxes) purposes. The gardens are being co-managed on a voluntary basis by the local communities with the help of an appointed gardener and an animator [1,4]. The project is based on 4 pillars: 1) social participation; 2) innovation; 3) social sensitivity; 4) food anthropology [5].

Tondiraba is a green urban area located in Lasnamäe, it is a valuable area with a diverse landscape which at the start of the initiative was severely overgrown and randomly used. The city planned to build an eco-golf course where the diverse and species-rich landscape and protected species are preserved. The architecture of the golf course is based on the advantages of the natural location and an ‘eco-golf course' concept. These landscapes and their flora were generated with landscape maintenance methods, which results in ‘micro-communities’ in which the ecosystems characteristic of the given area would start developing (ref 1, 5).

The abandoned fishing harbour in Tallinn is a derelict, privately owned but publicly used open space approximately 5 hectares in size and known as the former fishing harbour (Kalasadam). It is part of the old industrial waterfront belt waiting to be regenerated in the future. It is a piece of ‘urban wilderness’ (Ref. 1). The site is a green open space with high recreational values. Inserting a few pieces of equipment and taming the urban wilderness very slightly seems to lead to a significantly increased number of users than before these developments (Ref 2).
A research study has been done to determine whether an urban derelict site could be regarded as only empty and meaningless (ref 1 and 2)

Based on a neighbourhood survey the results pointed to a lack of green recreational spaces, in 2015 the citizens initiated a project to develop a new green square at the Zielona Street 19 in Gdynia. The project was implemented in 2018 and it aimed at improving the aesthetics of the district and provide green leisure space for the community. The initiative involves the management of the existing lawn, planting shrubs and trees, creating flowerbeds, building alleys and installing street lamps, creating variously-shaped wooden benches and litter bins, as well as building a fenced sandpit and a playground [1].

The NBS is a socio-ecological initiative to create an urban garden that would serve as an outdoor space for creative endeavours in the Cracow's district Podgórze. The project was implemented by an association of cultural institutions, NGOs, artists' groups, landscape architects, social activists, cultural animators and artisans, who also activated a group of volunteers from among the residents. The initiative involves several activities including greenery planting, horticulture/vegetable garden, ecological education and art workshops. Space is rented from the municipality as an act of protection of naturalistic landscape from over investment and new residential buildings in the area. It is surrounded by modern developments [1,3,4].
The social garden was established in 2013 and it is still functioning with its original purpose [3].

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 park of Dondaines is an agro-urban park of the city. This contrast is guaranteed by the ecological management of space that aims to promote biodiversity in this highly urbanized area. The Park of Dondaines is located in a strategic position, between the old and the new Lille, and creates a link between these two entities. The park hosts a pedagogical farm. It is a framework where the urban, the animals and the plants meet. It preserves plants and small animals by providing them with food and habitat. The cover of the periphery, planted with pines, ensures the continuity of the park with the new districts of Euralille(Ref 3).The place is a garden of representation, park of proximity, urban agriculture and food production space, pedagogical farm and event platform, and a place for sports and games (Ref 2, 5).

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).

Opened in June 2006, the Jean-Baptiste Lebas Park, which occupies a space once used for illegal parking and marred by 11 lanes of traffic, is surrounded by the boulevard of the same name. This park plays an important role in creating an urban green space into a derelict grey area. The park helped to increase the biodiversity of the area. It has an area of 3-hectare (7-acre) and it contains a large lawn with flowerbeds, play areas for children and places for playing "boules" (Ref 1).
