Regulatory Systems

Governance dynamics and spatial planning regulations are significant factors in the occurrence (or containment) of urban sprawl. However, qualitative investigations of the planning regulatory systems and practices, and governance arrangements that cumulatively stimulate suburbanisation, typically remain detached from land-change analyses. Based on the concept of institutional frames of spatial planning systems, this article elucidates how governance dynamics and spatial planning practices, at different scales, can partially explain suburban land-use patterns. The territorial transformations of two Southern European metropolitan regions, Barcelona and Milan, are examined through land-use data (1990–2012) at different territorial scales. Demographic (1991–2011) and administrative (2011) data are also analysed. In-depth interviews about individual and collective land management practices have been carried out, as well as document analysis concerning spatial planning laws and regulations. This research shows that the metropolitan character of urban sprawl originates from local planning practices mainly performed by municipal authorities through land-use micro-transformations. Further, it highlights the decisive role that higher-level institutions can play in land containment. Urban sprawl is hence not necessarily an unplanned phenomenon, but rather a ‘differently planned’ local and regional land-use strategy.

The City

Metropolitan regions with emerging vast agglomerations constitute a seemingly insurmountable challenge to urban design and regional planning. We diagnose decentralization, suburbanization, and urban sprawl. New methods need to be developed. Digital information technologies are challenging established understandings of the city. New, fictitious realities as immaterial, dynamic communication systems supply and compete with the "direct" reality of built architecture. We are aiming at the connected, intelligent house, a machine or a cyborg in a global network. In this new mobility the interactive house could become the cover of worlds without places - to the place of all places. Cities will become to be centerless huge megacities, along with a loss of their old center functions. New virtual - not really functional justified - centers will be established.

The City

This study attempts to measure and characterize urban sprawl using its multiple dimensions in the Jamnagar city, India. The study utilized the multi-date satellite images acquired by CORONA, IRS 1D PAN & LISS-3, IRS P6 LISS-4 and Resourcesat-2 LISS-4 sensors. The extent of urban growth in the study area was mapped at 1 : 25,000 scale for the years 1965, 2000, 2005 and 2011. The growth of urban areas was further categorized into infill growth, expansion and leapfrog development. The city witnessed an annual growth of 1.60 % per annum during the period 2000–2011 whereas the population growth during the same period was observed at less than 1.0 % per annum. The new development in the city during 2000–2005 time period comprised of 22 % as infill development, 60 % as extension of the peripheral urbanized areas, and 18 % as leapfrogged development. However, during 2005–2011 timeframe the proportion of leapfrog development increased to 28 % whereas due to decrease in availability of developable area within the city, the infill developments declined to 9 %. The urban sprawl in Jamnagar city was further characterized on the basis of five dimensions of sprawl viz. population density, continuity, clustering, concentration and centrality by integrating the population data with sprawl for year 2001 and 2011. The study characterised the growth of Jamnagar as low density and low concentration outwardly expansion.

The Relationship

Dispersed urbanization during the last half century has transformed metropolitan regions into well-connected, low-density residential areas. However, this kind of urbanization has changed irreversibly the traditional rural landscape around cities, leading to a new definition of ‘rurality’. The present work discusses the intimate relationship between urban sprawl and new forms of rurality. Considering economic downturns and the possible impact on landscape transformations, our study focuses on a representative Mediterranean case of urban sprawl (the metropolitan region of Athens, Greece). In this area, urban settlements expanded rapidly into fringe land, producing relevant socio-demographic transformations that have determined uneven changes in rural landscapes. A spatially-explicit investigation of local-scale dynamics that characterize population residing in sparse settlements over a long time period (1961–2011)—encompassing distinct phases of urban growth and rural development—is relevant for analysis of local changes in the relationship between sprawl and new forms of rurality. A new concept of ‘rurality’—adapting to rapidly-evolving, mixed rural/peri-urban contexts—require reframing the relationship between rural landscapes, scattered settlements, economic cycles and socio-demographic aspects, in the light of a truly sustainable development of local territories.

Urban Cycle

Urban growth is a largely debated issue in social science. Specific forms of metropolitan expansion—including sprawl—involve multiple and fascinating research dimensions, making mixed (quali-quantitative) analysis of this phenomenon particularly complex and challenging at the same time. Urban sprawl has attracting the attention of multidisciplinary studies defining nature, dynamics, and consequences that dispersed low-density settlements are having on biophysical and socioeconomic contexts worldwide. The present commentary provides a brief overview on nature and implications of the latent relationship between sprawl, demographic dynamics, and background socio-environmental contexts with special focus on Europe. Empirical evidence supports the idea that spatial planning should cope more effectively with the increasing environmental and socioeconomic exposure of European regions to sprawl and demographic transitions, being progressively far away from a traditional urban cycle with sequential waves of urbanization, suburbanization, counter-urbanization, and re-urbanization. Growing socio-ecological vulnerability of metropolitan regions was evaluated based on a literature review demonstrating how a better comprehension of the intimate linkage between long-term demographic dynamics and urban cycles is necessary to inform fine-tuned policies controlling sprawl and promoting a sustainable management of peri-urban land.
