“…At a regional/territorial scale, most scholars [24][25][26] use supervised or unsupervised semiautomatic classification of satellite imagery, often developing multitemporal analyses to detect change in land use/land cover (LULC) and soil sealing due to urbanization. Some researchers enhance their workflow by applying a model builder in a GIS environment to calculate landscape ecology metrics [27]. Others [28,29] analyze land cover changes by performing spatial linear regressions on LULC classes.…”

Soil sealing is a worldwide phenomenon of covering of natural or seminatural soil with impervious surfaces, such as built-up or paved surfaces. It is widely recognized as a major environmental issue which drives landscape fragmentation and ecosystem services degradation and loss. Italy is one of European countries with the highest extent of soil sealing. The most affected area is northern Italy, especially the Po Valley with more than 12% of sealed surfaces. According to official data, Veneto Region and the city of Padua are seriously affected by this phenomenon. The Biotope Area Factor is a consolidated ecological urban index for mapping soil sealing, adopted in different European cities to support urban planning; it expresses the ratio of the ecologically effective surface area in relation to the total land area according to land cover classes. The general aim of this study is to map and to assess soil sealing in the whole municipal territory of Padua using the Biotope Area Factor (BAF) index. We tested and adopted a digital land cover map together with aerial images to perform a BAF analysis on the whole municipal territory of Padua. By using sample areas previously analyzed, we validated our source data by a double spatial validation process; therefore, soil sealing analysis was scaled-up to the municipality territory. Results show that in the city of Padua, the average BAF index value is 0.6; totally permeable surfaces (BAF = 1) cover 59.5%, whereas totally “sealed” surfaces (BAF = 0) are 40.3% of the municipal territory (93 km2). Most of the sealed soil is located in the east sector and in the historical core of the city, with BAF values ranging from 0 to 0.2. A particularly critical area is identified within the new industrial area of the city, which is strongly affected by soil sealing. BAF maps are useful tools to identify critical areas by geovisualizing surface permeability at a very detailed scale and by enabling further analyses for hydrogeological risk assessment and urban climate regulation. Moreover, the use of BAF maps at urban scale today represent an important tool for urban management, especially for policy makers who are planning mitigation and compensation measures to control soil sealing.

“…Additionally, understanding on urban sprawl, especially in Asian countries, still heavily relies on qualitative discussion instead of quantitative analysis (Feng, 2008). Some scholars propose that urban sprawl needs to be quantitatively measured in order to determine whether it is on the rise or decline, and whether it is a recent occurrence or has been evident for a long time (Gerundo & Grimaldi, 2011;Bruegmann, 2015).…”

After more than half century has passed, urban sprawl remains as one of the most important and unresolved matters in the urban development process. This paper adopts "Bibliometrics Analysis" technique, which is a statistical analysis of scientific publications to review the studies on urban sprawl from the year 1996 till 2015 in order to identify the fundamental issues and problem of urban sprawl. This method allows the researcher to review the literature of topic of interest critically, not only based on national and international networks but includes the multi-disciplinary fields of science and technology relating to urban planning. The publications on urban sprawl were retrieved from the two largest scientific databases namely Scopus and ScienceDirect. The sampling of publications was based on the "Most Cited Articles" indicator. The findings on urban sprawl issues and problems are presented in four categories, which are the lack of consensus in defining urban sprawl, unavailability of method to quantify urban sprawl, access to data and tools, and varying urban sprawl patterns based on area. The findings of this study provide the gap for future research on urban sprawl.Keyword: Urban sprawl, sprawl issues and problem, urban sprawl planning, bibliometric analysis.

“…These include Shannon’s entropy (Jat, Garg, and Khare 2008), a shape and path index (Esch et al 2010) and the degree of goodness of fit (Bhatta, Saraswati, and Bandyopadhyay 2010) which was used to determine the direction, extent, pattern, rate, and concentration of urban sprawl. It is clear from the literature (Anselin et al 2000; Tsai 2005; Gerundo and Grimaldi 2011; Le Néchet 2012; Anselin 2012) that more spatial metrics and statistics (such as Moran statistics) that capture various aspects and relationships of urban growth are needed for urban planning.…”

Cities are constantly changing and authorities face immense challenges in obtaining accurate and timely data to effectively manage urban areas. This is particularly problematic in the developing world where municipal records are often unavailable or not updated. Spaceborne earth observation (EO) has great potential for providing up-to-date spatial information about urban areas. This article reviews the application of EO for supporting urban planning. In particular, the article overviews case studies where EO was used to derive products and indicators required by urban planners. The review concludes that EO has sufficiently matured in recent years but that a shift from the current focus on purely science-driven EO applications to the provision of useful information for day-to-day decision-making and urban sustainability monitoring is clearly needed.
