Native title of the NBS intervention
PLA BUITS (Urban Vacant Lots with Territorial and Social Involvement)
Short description of the intervention
This is a co-management initiative fostered by the City Council of Barcelona that aims to involve civil society in defining, installing and managing unused spaces across all districts of the city. The city council provides temporary use for public entities or non-profit associations to develop temporary uses and activities (from one year to three renewable years) in order to promote social activism and cohesion in the neighborhood. Most part of activities are social urban gardens (Ref 1). The initiative had 2 editions, with 12 projects in the first one (2013) and 5 projects in the second one (2015) (Ref. 12). One of the most popular projects is the community gardens such as ConnectHort, in Poblenou, dedicated to permaculture, which has allowed the restoration of an abandoned area through sustainable urban agriculture practices (Ref. 12). Another project, the Illa dels Tres Horts project in the Font de la Guatlla neighborhood, is an orchard where work is done with vulnerable groups and allow the recovery of vulnerable species (Ref. 12)

Goals of the intervention
The Municipal Plan for Urban Emptiness with Territorial and Social Implications (BUITS Plan) aims to stimulate disused land in the city of Barcelona, ​​through activities of public interest of a provisional nature, driven by public or private entities without a spirit of profit, favoring the involvement of civil society in the regeneration and dynamization of the urban fabric (4).
- Fill out spaces in disuse;
- Promote the involvement of civil society in the reinvention of unused land;
- Regenerate the urban fabric and induce social dynamism in the environment;
- improve the quality of life of people (7).
- promote certain projects that favor the occupation and use of certain empty spaces in the city (Ref. 9)
Quantitative targets
45 895 m2 won as spaces for stay and citizen use; 147 implied entities of the city; 11 spaces to contest in the 2015 edition (7). Sizes of the lots are, by contrast, far from uniform, ranging from 100 m² (1,076 sq. ft) to 1,000 m² (10,760 sq. ft) (1). While this distribution aims to be as egalitarian as possible in terms of location, the sizes of the lots are, by contrast, far from uniform, ranging from 100 m² (1,076 sq. ft) to 1,000 m² (10,760 sq. ft) (1).
The project generally focuses on rehabilitation of derelict areas for social use, but the application of GI/NBS interventions is highly common (Ref 6). The vast majority of projects are focused on urban gardening and horticulture (Ref 6).
Monitoring indicators defined
m2 of spaces for stay and citizen use in the city (Ref 1)
number of different empty spaces across the city where emergent actions and tactical urbanism with Pla BUITS is happening (3).

Implementation activities
Compared with the stand-alone operations implemented previously, the Pla Buits adopts a very different approach: it invites outside organisations to find specific solutions for individual cases. At the centre of this plan, drawn up by Barcelona’s urban planning department (Hàbitat Urbà), is an open competition, launched between 1 November 2012 and 1 February 2013, for the opportunity to temporarily – for a period of between one and maximum three years – manage one of 19 vacant urban lots in the public domain that were originally earmarked for housing, public amenities, streets or green spaces in the local area master plan (the Pla General Metropolità of 1976). These vacant lots are distributed evenly among the city’s 10 districts, with the final result of 12 projects selected in this first edition. For the second edition of the contest, the available lots were 11, with the concession of 5 for civil management (Ref. 4), with the majority of the activities being urban agriculture (Ref. 1)

Pla BUITS transferred rights to local communities so they could develop emergent actions in tactical urbanism at fifty different empty spaces across the city (3). For the second edition of the contest, the available lots were 11, with the concesion of 6 for civil management (Ref. 4), with the majority of the activities being urban agriculture (Ref. 1)

(Ref. 12)
Impacts, benefits
Please specify other economic impact
- Pla BUITS invited neighborhood entities to co-manage abandoned parcels, and as such is a way to make citizens co-responsible for the public environment they are living in (Ref. 13).
- local authorities found low-cost development solutions by temporarily turning over public spaces, free of charge, to bodies willing to manage them for non-profit uses, often in the context of a patronage-like partnership (Ref. 1)
- Those organisations whose projects were selected obtained a temporary licence to occupy their allocated space, which allows for private usage and for development that is reversible and funded by the organisation in question (Ref. 1)
- - Urban allotments offer logistical advantages and seem to be well suited to the interests of the city council: they require little in the way of roadways and represent savings for municipal maintenance departments. Furthermore, allotments are spaces that are closed off with residents’ consent; as they remain available only to those users who contribute to their upkeep, the result is the regulated appropriation of a previously abandoned space, thus freeing up resources for the city (Ref 1)
Description of environmental benefits
