Abstract:Urban expansion causes socioeconomic and environmental changes with unpredictable impacts on peri-urban land, especially in ecologically-fragile areas. The present study assesses the impact of dense and, respectively, discontinuous urban expansion on high-quality land consumption in 76 metropolitan regions of Mediterranean Europe. Land quality indicators and land-use maps were considered together with the aim to analyze urban growth and land take processes in Portugal, Spain, southern France, Italy and Greece.… Show more
“…Therefore, this paper assumes that population growth significantly contributes to stimulating NCL, and with the development of the advanced stage, this role gradually strengthens but then weakens. Notably, there is a decoupling between urban expansion and population growth in western developed countries (Arribas-Bel et al, 2011;Salvati et al, 2018). In other words, far from the core cities, land consumption increases while population size stabilizes or even declines.…”
This paper explores the factors affecting newly increased construction land (NCL) in China at different development stages based on supply figures for the land market in 2010–2015. The results reveal that with the progress of regional development, NCL gradually increases, whereas the dependence of regional development on NCL decreases. Moreover, the structure of NCL at different development stages differs significantly. Nonagricultural industry development, land resource scarcity, population growth, economic extroversion, and domestic capital have different effects on NCL at different stages of development. These differences are closely related to the socioeconomic characteristics of each development stage. These findings may enrich the study of urban expansion in China's economic transition. This paper suggests that the government should be aware of regional differences in NCL regulation.

“…Around the same time, touristic development fuelled construction on many coastal municipalities. During the first decade of the 21st century, even municipalities on the second line or in some cases further inland saw low-density residential development increase (Salvati et al, 2018).…”

“…Around the same time, touristic development fuelled construction on many coastal municipalities. During the first decade of the 21st century, even municipalities on the second line or in some cases further inland saw low-density residential development increase (Salvati et al., 2018). Figure 1.Location of Catalonia in the Western Mediterranean (top left), the 18 considered counties on the Catalan coast (top right) and the three local study cases: (a) Corbera de Llobregat, (b) Tiana, Alella and Teià (TAT) and (c) Calonge.…”
Studies addressing outdoor water use in residential areas rely on surveying methods, the manual digitization of aerial imagery and remote sensing-based approaches to estimate water consumption by different land uses. Publicly available cadastral data potentially offer a more efficient avenue for researchers to obtain information on land use parameters, but few assessments of their quality and applicability have been conducted. A sample of three local areas, encompassing more than 12,000 plots in low-density residential areas and representative of different socioeconomic profiles, were selected in the metropolitan area of Barcelona and along the Mediterranean coast of Catalonia. The reliability and sufficiency of the Spanish cadastre were assessed for the identification of swimming pools against the ground truth evidence provided by high-resolution aerial imagery and the support of object-based image analysis. Omission and commission errors of the cadastre were measured, the delimitation of digitized pool areas was statistically tested for accuracy, and the condition of the facilities was compared in the three study sites. The results do not support the use of the Spanish cadastre as a source of data for uses requiring a high level of detail and completeness. Plot size, socioeconomic and cultural factors affect pool size, the frequency of empty pools and the installation of pool covers in different communities. The study demonstrates that researchers need to complement cadastral data with qualitative information about the condition of the swimming pools to successfully estimate their cumulative water consumption at larger scales. Implications for water use research and spatial planning are discussed.
“…Whereas the multifaceted impacts of land consumption on soil resources, ecosystem services, landscapes and biodiversity are rather well-understood (Gerecke et al, 2019;Kroll, Müller, Haase, & Fohrer, 2012;Haase & Lathrop 2003;Salvati et al, 2018), the various driving factors behind urban growth are still a matter of controversial scientific debate (Colsaet, Laurans, & Lapuente, 2018). Classical models of urban spatial structure consider the growth of urbanized areas as a demand-driven phenomenon (e.g., van Vliet et al, 2016, Oueslati, Alvanides, & Garrod, 2015.…”
The conversion of open space to built land is a key feature of urbanrural transformations. In many countries, urban sprawl represents the dominant mode of urban growth. Against this background, urban growth management plays a crucial role in mediating between diverse spatial requirements and curbing sprawl-like land-use patterns, but its effectiveness is not fully understood. Relatively few studies have systematically addressed the goals of growth-management approaches, their implementation pathways and spatial outcomes. Most available work has been carried out as single case studies which hampers solid understanding. In this paper, we first outline the challenge in understanding the role of growth management approaches in land conversions. Then we propose research to focus on: a) comprehending the intended outcomes of growth management, and b) the effectiveness of growth management. We argue that future research in this regard will enable researchers to establish causal links between growth management and land conversions.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
