“…A comparative analysis of the three cities suggests that place-specific development models reflect a divergent spatial organization that may alter significantly the (presumed) homogeneity of forms and functions in Mediterranean cities [19,49,54]. In line with this assumption, the empirical results of our study indicate that Barcelona's province is a moderately polycentric region.…”

“…Rome's province is now officially designed as the 'metropolitan area of Rome' (following the prescription of a national Italian law from 2009) and covers nearly 5355 km 2 of land. The region is partitioned in 121 local municipalities that administer a relatively heterogeneous territory, with fragmented semi-natural landscapes that contrast with the compactness of the historical city of Rome, where upper socioeconomic functions are concentrated [52][53][54]. The city provides traditional and advanced services and thrives on the retail trade and tourism.…”

The present study illustrates a simplified procedure identifying population sub-centers over 50 years in three Southern European cities (Barcelona, Rome, Athens) with the aim to define and characterize progressive shifts from mono-centric structures towards a polycentric spatial configuration of (growing) metropolitan regions. This procedure is based on a spatially-explicit, local-scale analysis of the standardized residuals from a log-linear model assessing the relationship between population concentration and the distance from a central place in each metropolitan region, under the hypotheses that (i) a mono-centric spatial structure is characterized by a linear relationship between the two variables and that (ii) population sub-centers—considered early signals of a more polycentric regional structure—are characterized by high and positive regression residuals. Results of this study indicate that the three cities have experienced distinctive urbanization waves influencing the overall metropolitan configuration, with variable impact on the original mono-centric structure. Population sub-centers include (i) peri-urban municipalities around the central city and more remote towns situated in rural districts (Barcelona); (ii) scattered towns at variable distances (20–30 km) from the central city (Rome); (iii) fringe municipalities and peri-urban locations in flat districts, 10–20 km away from the central city (Athens). These results may indicate a distinctive evolution path toward polycentric development in the three cities, more evident in Barcelona and Rome and less evident in Athens. The proposed methodology can be generalized and adapted to discriminate population from employment sub-centers in metropolitan regions all over Europe.

“…In these cases, sprawl patterns evoke a Mediterranean style of urban growth, represented by the coexistence of traditional, multiple arrays of rural, low-density settlements (Figure 3) with a new, discontinuous urban fabric, making the spatial interpretation of landscapes even more difficult and less linear [84]. The most evident transformation in Southern European cities involves peripheral districts ( Figure 4), spreading chaotically into rural and empty spaces as a result of both planned and spontaneous urban practices [3,[85][86][87][88]. Suburbs have invaded natural landscapes through spatially extensive and discontinuous settlements, often following road and railway infrastructures [89][90][91][92].…”

Urban sprawl is a complex phenomenon that requires a comprehensive reflection on the most significant patterns and underlying processes. While the “sprawl” notion parallels hegemonic concepts such as economic competitiveness, social cohesion, and polycentric development, an integrated analysis of sprawl patterns and processes in paradigmatic socioeconomic contexts is increasingly required to reconcile different disciplinary visions, contributing to a holistic interpretation of metropolitan change. At the same time, sprawl is an increasingly evident product of local socioeconomic contexts all over the world. A comprehensive investigation of multifaceted, form–function relationships underlying sprawl—based on a quali-quantitative analysis of representative cases—is a crucial pre-requisite of both monitoring and policy actions at multiple spatial scales, from urban/regional to national/continental levels. The present contribution proposes a contextualization of the sprawl notion in Southern Europe—a socioeconomic context characterized by compact and continuous urbanization for a long time. An integrated approach based on a visual analysis of urban and peri-urban landscapes—integrated with an extended literature survey—allows for a definition of a specific sprawl model in Southern Europe, sharing some features with the United States ideal type of sprawl and showing peculiarities with respect to common models of urban dispersion typical of Northern and Western Europe. Policies aimed at containing urban dispersion may definitely benefit from a local-based definition of sprawl, considering the specificity of form–function relationships and the underlying socioeconomic context.

Effects of this transition on urban population gave rise to a slow shift from compact cities to more polycentric and spatially balanced areas (Rontos, 2010;Kabisch & Haase, 2011;Salvati et al, 2015). Both internal and foreign migration influenced demographic changes Source: Own elaboration on Eurostat Urban Audit data (Inner Cities and Large Urban Zones).…”

A complex interplay among socioeconomic transformations and the underlying demographic trends has occurred along the long-term development of European countries. For instance, fertility plays a key role along the urban-rural gradient contributing to understand population patterns and processes and allowing identification of factors, drivers and consequences of demographic transitions. This contribution focuses on the relationship between urban growth and demographic transition, discussing whether discontinuous and dispersed urban expansion can be associated with a specific phase of demographic transition, especially a higher suburban fertility compared with urban and rural areas. A review of the 'suburban fertility hypothesis' based on earlier studies carried out in advanced economies, with a specific focus on Europe, indicates that urban sprawl is associated to younger and larger families whose childbearing behaviors determine positive feedbacks in terms of local fertility and demographic dynamics at large, with spatial heterogeneity across European regions and countries.Sažetak: Tokom dugoročnog razvoja evropskih zemalja došlo je do složene međuzavisnosti između socio-ekonomskih promena i osnovnih demografskih trendova. Na primer, plodnost ima ključnu ulogu u urbano-ruralnom gradijentu, doprinoseći razumevanju populacionih obrazaca i procesa tako što omogućava identifikaciju faktora, pokretača i posledica demografskih tranzicija. Ovaj rad se fokusira na odnos između urbanog rasta i demografske tranzicije, raspravljajući o tome može li se diskontinuirana i raspršena urbana ekspanzija povezati sa specifičnom fazom demografske tranzicije, naročito sa visokim vrednostima suburbanog fertiliteta u poređenju sa urbanim i ruralnim oblastima. Peispitivanje "hipoteze o suburbanoj (prigradskoj) plodnosti" zasnovane na ranijim studijama koje su sprovedene u naprednim ekonomijama, sa posebnim fokusom na Evropu, ukazuje da je urbano širenje povezano sa mlađim i većim porodicama čija dečja reproduktivna ponašanja determinišu pozitivne efekte lokalnog fertiliteta i demografske dinamike uopšte, s prostornom heterogenošću širom evropskih regiona i zemalja.
