This article relates to the concept of urban expansion reduction in limited areas, called "de-sprinkling districts", and methods of designation of their range, as well as modelling and management of their network. This concept was developed from research concluded in 2016, referring to 50 years of urban evolution in Italy, that investigated and diagnosed the forms of urban growth focusing on the Italian model. For this model, the authors of this paper proposed an alternative definition (urban sprinkling) with respect to the sprawl international standard. Certainly this urban model established in Italy during the mentioned years is due to an inefficient control of peripheral areas and new conurbations' development, both in forms and functions. The cause is to be searched for in the importance given to single towns' general plans and the minor role of strategic planning (province and region). The political and social assumption that urban development according to the extreme sprinkling model is no longer feasible is gaining ground. However, implementing de-sprinkling processes will not be easy. In this paper, criteria to create a decision support system (DSS) for administrators and municipalities is illustrated. These criteria aim at dealing, technically and politically, with sprinkling and planning medium-term containment.

Land Squandering in the Spanish Medium Sized Cities: The Case of Toledo

A process of land squandering began in Spain in the mid 1990s until the great crisis of 2008. The intensive production of urban land affected the Spanish medium-sized towns. They were characterized by their compact nature and then they underwent an intense diffuse urbanization. However, in some cases there had been previous examples of urban sprawl. In this article, we study one of them, the unique and historic city of Toledo, in the Centre of the Iberian Peninsula. We will show how the city has experienced the land squandering and has been extensively widespread throughout the hinterland, consisting of their peripheral municipalities. We will also check how Toledo has had a previous internal dispersion process in the last quarter of the 20th Century through the called Ensanche (widening). We will use the urban estate cadaster as a fundamental source for evolutionary and present analysis of the city and its hinterland. The field and bibliographic work complete the methodology. The final conclusion is that there have been remarkable urban increments in Spanish medium-sized cities such as Toledo, in external and peripheral districts, under the logic of speculation and profit, resulting in a disjointed space.2 of 17 cities are characterized by the role played in the territory not only regarding the capacity to articulate their environment but also regarding the influence that they generate and the relationships that they are able to establish with other spaces. In short, it must be highlighted their role as carriers of goods and services to those cities and/ or rural municipalities on which they exert influence. In addition, their ability to connect different levels of networks (at a local, national, and even international level) is remarkable [9].The definition of intermediate cities with their clear vocation of intermediation, left the quantitative criteria behind to conceptualize from the explanation of qualitative, economic, functional and territorial factors, where the capacity to organize more balanced urban systems with a higher quality of life is essential [10].The most recent studies on medium-sized cities have been approached from different perspectives (scattered and oversized growths-in most cases-which leave the traditional compact city model aside) that share one thing in common: the model of diffuse city. However, the term is not subject to a concise definition. On the contrary, and it is the same as with the concept of medium-sized cities, this reality associated with urban sprawl does not have a clear definition since their building density, the morphological typologies, the intensity of use and/or the possible territorial effects to which urban dispersion refers are unknown [11].This phenomenon has been characterized from different terms that come to represent a similar reality: city-region [12], urbanized field [13], diffuse city model [14], city sprawl [15], no city [16], inefficient city [17]. The explanatory processes that derive in this situation are also complex and are hidden under vague ter...

“…This is true, for example, in large regions of the Continental Portuguese territory, where urban diffusion largely consisted of a large land take with a partially spontaneous development, or subject to low controls, adding on to a historical structure. This artificialization pattern, characteristic of very low human population densities, was initially defined as sprinkling by Romano and Zullo (2016) in the Po Valley and later analyzed in the whole Italian territory (Romano et al, 2017a). These newly built-up areas account for a small fraction of the total territory.…”

A land-cover based urban dispersion indicator suitable for highly dispersed, discontinuously artificialized territories: The case of continental Portugal

et al. 2019

A B S T R A C TLand-cover based indicators assessing the effect of the magnitude and spatial patterns of the artificialization process, including urban sprawl, barely consider the impact of the discontinuous spatial distribution of the artificialized built-up areas. In this study, we propose a new urban dispersion indicator, which incorporates the characteristic dynamics of the discontinuous urban artificial land cover class, characteristic of scarcely populated and highly dispersed territories, such as is the case of Continental Portugal. The indicator is based on the premise that the more built-up area, the higher the uptake of constructed area in a discontinuous pattern and the more dispersed this built-up area, the lower urban sustainability of the territory. Given that the minimum cartographic unit in Corine Land Cover (25 ha) is typically higher than most of the discontinuous urban patches in these territories, in this research we used national land use data from Portugal with a minimum cartographic unit of 1 ha.The values calculated for this indicator show that the level of urban dispersion of continental Portugal increased by 14.2% in the 1990-2007 period. The artificialization process was geographically heterogeneous with notable differences being observed between regions and also along the urban to rural and coastal to hinterland gradients. The temporal changes in the indicator allowed the identification of distinct artificialization patterns: diffusion, sprinkling and coalescence, which were interpreted on the basis of the evolution of the artificialization process. The values derived from this indicator were related with two main environmental impacts associated with the artificialization process: the loss of arable land and the decrease in the carbon sequestration capacity of the territory. The proposed indicator can be a useful tool to monitor and evaluate the impacts of different public policies with a direct impact on land artificialization, as well as on the territorial and urban planning processes, whether at the national, regional or municipal level, allowing more detailed and consistent spatial analyses and diagnoses of urban sustainability to be undertaken. for about 38% of Earth's terrestrial surface, the largest use of land on the planet, whereas 30% was covered by forests (Foley et al., 2011).
