Institutional Blendscapes: The Suburban Governance Role of the Diputación de Barcelona

The analysis of suburbanization patterns and processes necessarily implies looking beyond towns and cities. Suburbanization is a blendscape because it occurs within the transition zone between urban and rural areas surrounding urban centres. Therefore, a tension emerges between the growth expectations of small- and medium-sized municipalities and the supra-local authorities (e.g. metropolitan, provincial or regional public bodies) that provide essential (mostly financial) support to those municipalities. Supra-local authorities hence perform the governance role of institutional blendscapes because they can mediate between those growth expectations and more efficient, area-wide land management. By using the Barcelona Province as a case study, this paper examines three inter-related issues in suburbanization processes: (i) the question of land transformation; (ii) the relation between municipal size and suburban pa erns; and (iii) the role of supra-local authorities in the management of suburban areas in the city outskirts. Findings show that, overall, while municipalities up to 9,999 inhabitants have a housing stock that is predominantly suburban in character (i.e. 76.5 per cent single-family dwellings), it is small-/mid-sized municipalities between 10,000 and 49,999 inhabitants that have the highest proportion (31.2 per cent) of suburban residential areas within the Barcelona province. These small- and mid-sized, often rural, municipalities tend to rely on financial and technical support from the supra-local authority of the Barcelona Diputación – a key governance actor in suburbanization processes. As an institutional blendscape, on the one hand, the Barcelona Diputación can steer a more efficient land allocation and management through environmental protection and assistance in developing (supra-)local spatial plans. On the other hand, by distributing essential financial help to provide basic public services in small- and mid-size suburban municipalities, it also partially mitigates the planning, construction, and maintenance of suburbanity in (very) small- and medium-size municipalities 'far from the city' and rural areas.
