“…The study area covers the entire territory of the Basilicata region (Southern Italy-see Figure 1), which is characterized by a traditional agricultural vocation and where the process of abandonment, rewilding, and fragmentation of rural areas is extremely topical [35,36]. Two main territorial compartments have been identified, corresponding with the administrative division of the two provinces: the province of Potenza, the regional capital, has mountainous and hilly terrain, including the Apennine Ridge and some of the most significant mountain ranges in southern Italy; the province of Matera is orographically constituted by the clay terraces of the Fossa Bradanica, which slope with hilly undulations towards the Apulian Region to the east and towards the coastal plain that hosts the mouths of the main Basilicata rivers to the south-east.…”

Vernacular Farm Buildings and Rural Landscape: A Geospatial Approach for Their Integrated Management

Over the centuries, farm buildings, which accompany the development of agriculture, have played an important role in defining spatial and environmental planning. In some European countries in particular, these rural structures have been built based on traditional agricultural needs and typical land characteristics. Considering the land abandonment that has occurred over the last five decades, with farmers moving to more comfortable residences in neighboring urban settlements, historical farm buildings have often been abandoned, thus causing a leakage of the historical-cultural heritage of the rural landscape. Nowadays, open data and geographic technologies together with advanced technological tools allow us to gather multidisciplinary information about the specific characteristics of each farm building, thus improving our knowledge. This information can greatly support the protection of those buildings and landscapes that have high cultural and naturalistic value. In this paper, the potential of Geographic Information Systems to catalogue the farm buildings of the Basilicata region (Southern Italy) is explored. The analysis of these buildings, traditionally known as masserie, integrates some typical aspects of landscape studies, paving the way for sustainable management of the important cultural heritage represented by vernacular farm buildings and the rural landscape.

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...

“…Urban sprawl and sprinkling have been characterized based on the densities of human population and residential buildings (Saganeiti et al, 2018). Urban sprawl is characterized by low values of both variables, with values of 6 and 12 residential buildings per hectare and 20-150 inhabitants per hectare.…”

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).
