Full textAbstract:
Identifying the effects of urban sprawl on urban development is of strategic importance. This study takes 285 prefecture-level and above cities in China as research samples and empirically analyzes the heterogeneous impact of urban sprawl on economic development from 2009 to 2018. Results indicate the threshold effect of urban sprawl on economic development. That is, moderate urban sprawl has a significantly positive influence on economic development, whereas excessive urban sprawl has a significantly negative impact on economic development. The empirical analysis also identifies heterogeneities in the effects of urban sprawl on economic development. Compared with the sprawls of small- and medium-sized cities, those of large cities have a greater negative impact on economic development. Compared with the sprawls of cities dominated by the tertiary industry, those of cities dominated by the secondary industry have a greater negative impact on economic development. Findings of this study have important policy implications for scientific urban expansion, reasonable urban spatial layout, and sustainable urban economic development.

Full textAbstract:
The authors begin with an overview of the causes and consequences of urban sprawl in the twentieth century, focusing in particular on lower transportation costs and self-sorting of the population. By sprawl, we will mean the tendency toward lower city densities as city footprints expand. They next focus on four issues that raise clear efficiency and equity concerns: unproductive congestion on roads, high levels of metropolitan car pollution, the loss of open space amenities, and unequal provision of public goods and services across sprawling metropolitan suburbs that give rise to residential segregation and pockets of poverty. Finally, they consider the trade-offs inherent in some policies commonly proposed to address urban sprawl. Throughout, a main theme of the discussion is that a full analysis of sprawl is made difficult by the lack of a usefully integrated economic model of urban economies. Along these lines, the authors conclude with some thoughts on possible future research agendas.

In Jos metropolis, urban sprawl debate has closely paralleled on urban growth trends over the past few decades. These studies indicate that it is the pattern, types, density and rate of new urban growth that creates the appearance of sprawl. Population dynamics are often cited as a driving force behind urban sprawl. This paper uses Geographic Information Systems (GIS) mapping and land cover change analysis, neighbourhood statistics, cross change detection techniques, field work on Urban sprawl areas in Jos metropolis. The paper also highlights the characteristics, types, rates, pattern and density of sprawl to examine the spatial pattern of sprawl in Jos North and Jos South. Linear sprawl pattern can only be visually seen by the road, the roads in Jos play important role in linear pattern of urban sprawl formation through road data, it helped to visualize clearly the areas of linear sprawl in Jos metropolis. An example can be visually seen in Naraguta area, part of a large high residential development of Jos north. Cluster types of urban sprawl settlement development in Jos metropolis. From the map, it shows that cluster types of sprawls in study area are found in the core city of Jos metropolis like Jos city and Bukuru in the study area. Cluster type of urban sprawl also appeared to grow out of what was once a leapfrog pattern of development in some area in the study area. Leapfrog patterns of urban sprawl appeared to be somewhat disconnected from other areas of existing developed settlement land. Leapfrog types of urban sprawl in Jos metropolis can be seen in Kuru North, Dan Miangu, Barakin Kuru and Kuru Hills.After the map of the densities urban sprawl for new growth areas has been created. The study reveals that settlement area has increase from 125.45 to 208.16 sq.km between 2002-2022 in twenty years period. It also revealed that water bodies have also drastically reduced by 3.33 sq.km and open space land use contributed about 127.57 km2 land converted to settlement within the time under study. Further analysis reveals that the urban settlement land of the area increased approximately 82.71 km2 in the twenty years’ time period of the study (2002 to 2022). Next, the patterns of urban expansions were analyzed by using mapping capabilities within the GIS and neighborhood statistics in order to show the density and connectivity of patches of new growth. Based on the density and connectivity of new growth areas, the patterns of growth were classified as: linear along highways, cluster, and leapfrog. The threshold densities are; 0 to 2000 as 30-meter pixels per km2 for low density, 2000 to 25000 for medium density, and 25000 to 130000 for high density. The results indicate that Jos metropolis did experience an increase in urban growth from 2002 to 2022 and that urban growth in the study area can be classified as urban sprawl. The density of new development is more in Jos North, but the pattern and character with which development has occurred in Jos North is synonymous with sprawl in Jos South. the type, rate and patterns of urban expansions were analyzed by using mapping capabilities within the GIS and neighborhood statistics in order to show the density and connectivity of patches of new growth in the study area.

Full textAbstract:
Urban sprawl in China presents unique characteristics that differ from those commonly studied in Western contexts, an aspect not fully explored in previous studies. Therefore, taking Wuhan, Hubei as an example and integrating population data, remote sensing data, and POI data, this research offers a perspective on sprawl development in urban China. By incorporating population, urban land use, and urban amenities, this study measures their dynamics to classify urban spaces and employs spatial regression models to identify the characteristics of sprawl development with spatial effects controlled. It further applies geographically weighted regression to examine the underlying spatial heterogeneity. The findings indicate that population growth and urban land expansion do not align perfectly, and further exploration identifies the various trends of sprawl development in urban core and periphery areas. On the other hand, some suburban areas show compact development trends, but the growth of local amenities may be limited due to the historical sprawl development legacies. Regression results reveal specific characteristics of this sprawl development. Key findings include the following: (1) shaped by the triple process of sprawl development of urban renewal, suburbanization, and rural revitalization, Wuhan shows a significant core-periphery structure with the trend of polycentricity; (2) overcrowding in central urban districts is the primary driver of sprawl development; (3) most traditional suburbs in Wuhan have emerged as a consequence of rapid urbanization with a legacy of sprawl development; (4) spatial heterogeneity across urban spaces highlights the necessity for locally tailored approaches to regulating sprawl development.

Full textAbstract:
Against the background that urbanization has proceeded quickly in China over the last two decades, a limited number of empirical researches have been performed for analyzing the measurement and driving forces of urban sprawl at the national and regional level. The article aims at using remote sensing derived data and administrative data (for statistical purposes) to investigate the development status of urban sprawl together with its driving forces. Compared with existing studies, NPP/VIIRS data and LandScan data were used here to examine urban sprawl from two different perspectives: urban population sprawl and urban land sprawl. Furthermore, we used population density as a counter-indicator of urban sprawl, and the regression results also prove the superiority of the urban sprawl designed by us. The main results show that the intensity of urban population sprawl and urban land sprawl has been enhanced. However, the upside-down between the inflow of migrants and the supply of urban construction land among different regions aggravates the intensity of urban sprawl. According to the regression analyses, the driving mechanism of urban sprawl in the eastern region relying on land finance and financial development has lost momentum for the limitation of urban construction land supply. The continuous outflow of population and loosely land supply have accelerated the intensity of urban land sprawl in the central and western regions. The findings of the article may help people to realize that urban sprawl has become a staggering reality among Chinese cities; thereby urban planners as well as policymakers should make some actions to hinder the urban sprawl.

Full textAbstract:
Urban sprawl concerns the high-quality and sustainable development of large cities. Due to the ambiguous definition, diversity of measurement indices and complexity of the driving mechanism of urban sprawl, the research results are rich but controversial. How does one carry out multidimensional measurement of urban sprawl? How does one reveal the spatio-temporal evolution characteristics of urban sprawl dynamically? First, according to the three common characteristics of urban sprawl (discontinuity of land use, low population density and inefficiency of land use), we, respectively, measure the urban sprawl of Shanghai metropolitan area by single index and comprehensive indices based on multi-source geospatial data. Next, using geographic information system (GIS) method, the temporal and spatial characteristics of urban sprawl in Shanghai are quantitatively and dynamically analyzed. The results show that (1) land use continuity reveals that fringe expansion is the main mode of urban sprawl, population density exhibits an upwards trend, and land use benefit shows that the sprawl increased first, then decreased and increased again, i.e., “N” type trend. The results of the above three comprehensive superpositions indicate that the urban sprawl in Shanghai changed from severe in 1995 to mild in 2010 and in 2020. (2) From 1990 to 2020, urban sprawl in Shanghai showed a trend of decreasing first, then increasing and decreasing again, which is consistent with an evolutionary trend of newly increased construction land. The larger the sprawl area was, the lower the land use efficiency of the sprawl area was. (3) The main directions of urban sprawl were southeast and southwest, and Songjiang District and Pudong New Area were the main sprawl areas. The peak value of urban sprawl mainly occurred at 20–30 km and was located in the area between the outer ring and the suburban ring. (4) Through time series analysis, we found that the effective supply of housing significantly affected the intensity and scale of urban sprawl but not the speed of urban sprawl in Shanghai metropolitan area. These findings are helpful to reasonably evaluate the real picture of urban sprawl in Shanghai metropolitan areas and provide reference for the formulation of urban sprawl governance policies.

Urban sprawl has become the main pattern of spatial expansion in many large cities in China, and its ecological and environmental effects profoundly impact Chinese urban development. In this paper, nighttime light data and statistical yearbook data are adopted as basic data sources to simulate the evolution trend of the urban sprawl in the upper Yangtze River (UYR), China. First, the urban sprawl index (USI) is employed to assess the level of urban sprawl and to determine the characteristics of urban sprawl under different scales. Second, the spatial autocorrelation model is applied to reveal the spatial pattern change characteristics of urban sprawl from 1992 to 2015. Third, a scenario analysis model of urban sprawl is constructed to simulate the evolution trend of the urban sprawl under different scenarios. Finally, based on the Geodetector, the influence of factors and factor interactions influencing urban sprawl in different time periods is analyzed. The results yield the following main conclusions: (1) The urban sprawl in the UYR first intensifies and then stabilizes over time. The number of cities with high USI in Sichuan province, medium cities, and Chengdu-Chongqing urban agglomeration increases over time, indicating that urban sprawl is intensifying in these areas. (2) The urban sprawl hot spots experience a pattern transformation process of point-like expansion-point-ring expansion-point-axis expansion-axis radiation. (3) Under the scenarios with different scales, the urban land sprawl in large cities is the highest, accounting for more than 47% of the UYR. Urban land sprawl extent in the Chengdu-Chongqing urban agglomeration is the highest, accounting for more than 51% of the UYR. The cities exhibiting the highest sprawl are Chongqing, Lijiang, and Kunming, accounting for 25.84%, 7.37%, and 5.11%, respectively, of the UYR. (4) In the different time scenario simulations, the urban land in large cities exhibits the highest sprawl, accounting for approximately 48.16% of the UYR. The urban land in the Chengdu-Chongqing urban agglomeration demonstrates the highest sprawl, accounting for 50.92% of the UYR. (5) From 1996 to 2002, the driver with the highest influence on urban sprawl was secondary industry share of GDP, with a q-statistic of 0.616. From 2009 to 2015, the driver with the highest influence on urban sprawl was green space per capita with a q-statistic of 0.396.

Purpose Iran’s metropolitan areas are growing rapidly, and, among them, Shiraz has experienced a high rate of urban sprawl in recent decades. On the other hand, besides wasting the resources, urban sprawl does not follow the principles of sustainable urban development and its consideration would help to determine and employ the required type of sustainable urban development approach. The purpose of this paper is to assess urban sprawl in Shiraz. Design/methodology/approach First, the indicators and their weights for Shiraz’s sprawl assessment are identified through Delphi and analytical hierarchy process (AHP) methods. In addition, the degree of urban sprawl is assessed using the preference ranking organization method for enrichment evaluations (PROMETHEE). Findings The Delphi method produced the four criteria of “land use,” “urban fabric,” “social characteristics,” and “accessibility,” and “urban fabric” was the most important criterion per the AHP. Finally, the results of the PROMETHEE analysis indicated a high amount of urban sprawl in most of Shiraz’s municipal zones. Practical implications Therefore, due to the high degree of urban sprawl in Shiraz and its geographical limitations for horizontal development, a study on sustainable approaches to urban development in Shiraz, including Smart Growth and sustainable urban regeneration, seems mandatory for this city. However, this study indicates the requirement for more studies on urban sprawl in major cities of Iran, but by comparison of these findings with other relevant studies, it is inferred that using sustainable urban development approaches seems crucial for the majority of the cities in this country. Finally guidelines on how to impede urban sprawl and encourage sustainable urban development in Shiraz and Iranian cities as well as certain implications in this regard are discussed. Originality/value The findings of this study are expected to contribute valuable information for policy makers in terms of urban planning and the development of the cities in Iran.

In recent years, China’s urbanization rate has been increasing rapidly, reaching 59.58% in 2018. Urbanization drives rural-to-urban migration, and inevitably promotes urban sprawl. With the development of remote sensing and geographic information technologies, the monitoring technology for urban sprawl has been constantly innovated. In particular, the emergence of night light data has greatly promoted monitoring research of large-scale and long-time-series urban sprawl. In this paper, the urban sprawl in China in 1992, 1997, 2002, 2007, 2012, and 2017 was identified via night light data, and the Artificial Neural Network-Cellular Automata-Markov (ANN-CA-Markov) model was developed to simulate the future urban sprawl in China. The results show that the suitability of urban sprawl based on the ANN model is as high as 0.864, indicating that the ANN model is very suitable for the simulation of urban sprawl. The Kappa coefficient of simulation results was 0.78, indicating that the ANN-CA-Markov model has a high simulation accuracy on urban sprawl. In the future, the hotspot areas of urban sprawl in China will change over time. Although the urban sprawl in the Beijing-Tianjin-Hebei region, the Yangtze River delta, and the Pearl River delta will still be considerable, the urban sprawl in the Chengdu-Chongqing city cluster, the Guanzhong Plain city cluster, the central plains city cluster, and the middle reaches of the Yangtze River will be more prominent. Overall, China’s urban sprawl will be concentrated in the east of Hu’s line in the future.

Full textAbstract:
Urban sprawl is widely acknowledged as an environmental and socio-economic challenge worldwide. This study examines urban sprawl in Belgium over six decades from 1950 to 2010. We assume that sprawl is a self-reinforcing process, i.e., sprawl is fueling further sprawl over time. The main objective of this study is to examine this assumption. We measure urban sprawl at four different levels in this study: country, regions, municipalities, and 1-km2 cells. Three sprawl indices are employed: the degree of urban dispersion, degree of urban permeation of the landscape, and built-up land uptake per capita. These three indices consider both the growth of built-up areas and population density to measure the magnitude of sprawl. The drivers of urban sprawl have been analyzed at a 1-km2 level. The examined drivers are previous urban dispersion patterns, distance to urban cores, elevation, and slope degree by means of linear regression. Urban sprawl significantly increased between 1950 and 1980, whereas its increase was more moderate between 1980 and 2010. Urban dispersion and permeation strongly affect the Brussels and Flanders regions. The results show that the increase in the degree of dispersion is locally driven by previous values of dispersion; i.e., it provides an adequate milieu for further dispersion. Therefore, our conclusion is that urban sprawl in Belgium tends to be a self-reinforcing process.

Full textAbstract:
In the context of rapid urbanization, inefficient, disorderly, and low-density urban sprawl often leads to resource waste and ecological damage. Over the decades, many studies on the measurement, analysis, and governance of urban sprawl have emerged. However, existing approaches lack in-depth research on distinguishing effective expansion from inefficient sprawl. Given the limit of land use resources and the demand for urban development, an accurate and reasonable method for urban sprawl measurement is needed. This study proposes an urban sprawl identification method based on a mechanical equilibrium model to analyze the spatial distribution and spatiotemporal evolution characteristics of inefficient sprawl, using the Yangtze River Delta’s (YRD) urban agglomeration as an example. The study found the following: (1) The inefficient sprawl in the YRD was 5219, 1189, and 980 km2 in the three five-year periods between 2005 and 2020. (2) From 2005 to 2020, the inefficient sprawl in the YRD was, on the whole, a weakening trend, but Shanghai and Zhoushan showed an accelerating trend of inefficient sprawl. (3) The proposed method is applicable to most urban development patterns and provides implications for urban sprawl control in mega-urban agglomeration areas, such as the YRD.

Full textAbstract:
Under the urban development trend of sprawl, improving energy use efficiency is a proper way to promote green and low-carbon construction in cities. This paper uses panel data from 283 prefecture-level and above cities in China from 2008 to 2019 to measure the urban sprawl index, and analyze the spatial-temporal evolution law of urban sprawl and electricity consumption. The relationship between urban sprawl and electricity consumption is empirically examined, and the differential effect of urban sprawl on electricity consumption is analyzed. Finally, the impact of urban sprawl on electricity consumption based on a spatial perspective is explored in depth by establishing a spatial error model. We found the following: (1) The levels of urban sprawl and urban electricity consumption are on the rise. The spatial distribution of urban sprawl is more dispersed, and cities with high electricity consumption levels are mostly concentrated in the eastern coastal areas. (2) Urban sprawl exacerbates electricity consumption, and this conclusion is still robust after a series of robustness tests were conducted and endogeneity issues were taken into account. In terms of the influence mechanism, urban sprawl mainly affects electricity consumption by changing the allocation of land resources, increasing the dependence on private transportation, and inhibiting green technology innovation. (3) The incremental effect of urban sprawl on electricity consumption is more pronounced in cities with high sprawl levels, weak environmental regulations, and low green innovation levels, as well as in west cities. (4) Urban sprawl and electricity consumption both have a significant positive spatial correlation. Electricity consumption of cities is not only related to their own regions but also influenced by the adjacent regions, and the spatial correlation is mainly reflected in the random error term. This paper deepens the understanding of the basic laws of urban sprawl affecting urban low-carbon development, which also has implications for new urbanization strategies and green development.

Full textAbstract:
Recently a number of studies have focused on urban sprawl in the Iranian cities and the negative impacts of such development pattern. Although in a general view the phrase ?urban sprawl? is used for fast and sometimes uncontrolled urbanizations, but there are dissimilarities between the urban sprawl in the western societies with the so-called Iranian urban sprawl. This paper discusses these differences as part of five main aspects that are mentioned in the internationally recognized urban sprawl definitions. Suburban sprawl, single-use developments/zoning, disconnected street network, low accessibility of the new developments, and commercial strip development are the aspects that are descriptively discussed as the main differences between the two types of sprawl. The main point of the discussion is that due to the wide range of similarities, which are briefly introduced, the type of the fast outward urban growth that is observed in the periphery of the Iranian cities can be defined as a part of the universal urban sprawl trend. Finally a definition is suggested for explaining urban sprawl in Iran.

Full textAbstract:
With rapid urbanization in China, the phenomenon of urban sprawl has become prominent and has severely challenged sustainable urbanization and ecological civilization. Aiming to understand the impact of urban sprawl on the urban environment, this study calculates the eco-efficiency of 264 prefecture-level cities in China from 2003 to 2016 by using a super-efficiency data envelopment analysis model. Then, we establish a panel Tobit model and threshold regression model to empirically test the impact of urban sprawl on eco-efficiency and the threshold effect of the urban scale. The results show that urban sprawl hinders the improvement of urban eco-efficiency, especially in Eastern China, but relatively weak or even insignificant effects are observed in Central and Western China. Additionally, a threshold effect of urban sprawl on eco-efficiency can be found. When the city scale is small, urban sprawl seriously hinders the improvement of eco-efficiency. As the city scale gradually expands, the negative effect of urban sprawl on eco-efficiency first decreases, then the restraining effect is gradually strengthened. Our research findings can aid urban development in cities with different scales to reduce the negative effect of urban sprawl on the urban environment.

The increasing conversion of agricultural land to non-agricultural land is the central issue in Karawang Regency. It is caused by the increasing population, urbanization, industrialization, urban expansion, and its position in the Jakarta Bandung Mega Urban Region (JBMUR) corridor. The increasing need for space in urban areas encourages the development to the city’s outskirts (urban sprawl). Urban sprawl is the biggest challenge in Karawang Regency’s spatial planning. The purpose of this study is to identify the spatial pattern of urban sprawl conditions formed from 2009 until 2018 and projecting urban sprawl in 2018 until 2031 as a recommendation for controlling space use for agricultural land development. The method used is urban sprawl analysis with related research, Moran index autocorrelation analysis and Local Indicator of Spatial Association (LISA), analysis of land use alignment and spatial patterns of spatial plan, and overlays. The results of this study indicate that the spatial distribution of urban sprawl occurs along the Cikampek, Telukjambe Barat, Telukjambe Timur, Pangkalan, and Tegalwaru toll roads. The urban sprawl that occurred in 2009 until 2018 has the type of leapfrog development. There was a change to the kind of urban sprawl to kind of ribbon development and an increase in the urban sprawl of 67.14 km2 in the projected urban sprawl in 2018 until 2031. Land use with conformity is much broader than land use that is not aligned with spatial planning. Therefore, first priority recommendation for agricultural land development still dominates in Karawang Regency.

<p class="Abstract">Urban sprawl merupakan fenomena yang terjadi akibat perkembangan kota yang semakin pesat, tetapi memiliki keterbatasan lahan sehingga perkembangan kota semakin meluas ke wilayah pinggiran (sub-urban). Wilayah sub-urban yang masih tergantung kepada kota inti juga menjadi salah satu pemicu proses urbanisasi terjadi di wilayah pinggiran tersebut (Soetomo, 2009). Fenomena tersebut terjadi di Kota Semarang yang terus berkembang, tetapi memiliki keterbatasan lahan. Kondisi tersebut menyebabkan terjadinya perkembangan kota hingga melewati batas administrasi salah satunya ke arah Kabupaten Demak. Penelitian ini bertujuan untuk mengkaji bagaimana perkembangan sprawl Kota Semarang pada wilayah Kabupaten Demak selama tahun 2001-2012. Urban sprawl pada penelitian ini ditinjau dari dua dimensi yaitu dimensi fisikal dan non fisikal. Dimensi fisikal meliputi pemanfaatan lahan, kepadatan bangunan, fungsi bangunan dan tingkat aksesibilitas. Dimensi non fisikal meliputi kepadatan penduduk dan mata pencaharian agraris penduduk. Sprawl Kota Semarang pada wilayah Kabupaten Demak selama tahun 2001-2012 telah bertambah seluas 498,685 Ha (32,23%), yang terdiri dari perubahan dari urban sprawl menjadi non-urban sprawl sebesar 488,278 ha dan perubahan dari non-urban sprawl menjadi urban sprawl sebesar 986,963 ha. Perkembangan sprawl memiliki pola kombinasi ribbon development dan leap frog development. Wilayah Kabupaten Demak dengan jarak 7,5-10 km dari pusat Kota Semarang (ring 1) merupakan wilayah yang mengalami perkembangan urban sprawl terbesar. Hal ini menunjukan bahwa jarak terhadap pusat kota menjadi salah satu faktor yang berpengaruh terhadap terjadinya sprawl. Untuk mengatasi perkembangan sprawl agar tidak semakin meluas diperlukan kebijakan mengenai arahan pengembangan perumahan pada kawasan urban sprawl, penambahan fasilitas umum dan penyediaan sarana dan prasarana angkutan masal yang terintegrasi dengan terminal terdekat di Kota Semarang.</p><strong></strong>

Full textAbstract:
The Japanese City Planning Act aims to control urban sprawl and promote compact urban development. Despite Japan’s aging population, urban sprawl remains a concern in shrinking sprawl situations. This impacts ecosystem services owing to the loss of natural areas. Ecological quality is regarded as a basic parameter for preventing urban sprawl. This study examined urban sprawl, ecological quality, and their relationship in Chiba Prefecture within the spatial context of the metropolitan region. Utilizing Shannon entropy and landscape metrics for urban sprawling studies, the analysis revealed a gradual shift towards compact development at the center, while the urban periphery was unevenly distributed. The remote sensing ecological index (RSEI), supported by remote sensing, assesses ecological quality. Despite some limitations, the average RSEI indicated moderate quality, offering a suitable human environment. Pearson’s calculations were used to determine the inverse correlation between urban sprawl and ecological quality. Chiba’s slight increase in sprawl was attributed to the transition from non-compact to eco-city development. The proposed plans were formulated based on similar urban sprawl and RSEI patterns in other cities for further sustainable compact development.

Urban sprawl related to rapid urbanisation in developed and developing nations affects sustainable land use. In Sri Lanka, urban areas have mostly expanded in a rather spontaneous, unplanned manner (based on the current settlers’ subjective movement) rather than conforming to the local government’s development plan. This growth inevitably leads to uncontrolled urban sprawl in many Sri Lankan cities, including Batticaloa. So far, Sri Lanka’s planners or researchers have not yet tackled the sprawling developments in this city. Understanding the different forms and patterns of urban sprawl is the key to address sprawling growth. This study aims to identify the characteristics of urban sprawl in the Batticaloa municipal council using Geographic Information System (GIS) and remote sensing technology. Landsat satellite images for the years 2000, 2010, and 2020 as well as 2002, 2011, and 2019 population data were used and analysed using ArcGIS’ maximum likelihood classification tool and the density function, respectively, to delineate the characteristics of urban sprawl. The results revealed that low-density development, leapfrog development, commercial ribbon development, and scattered growth are the influencing characteristics of urban sprawl in the Batticaloa municipality. These characteristics were found mainly in the urban edge of the city and have led to urban sprawl. The finding provides knowledge into recognising the characteristics of urban sprawl with empirical evidence. It affords a clear direction for future studies of urban sprawl in rapidly growing cities that are numerous in Sri Lanka, and the identified characteristics of urban sprawl can be useful in minimising future sprawl. This result can be a tool for future urban planning and management in the Batticaloa municipality.

Daerah rentan banjir adalah daerah yang berpotensi tinggi untuk terlanda banjir. Tingkat kerentanan banjir dapat ditentukan berdasarkan curah hujan, kelerengan lahan, struktur tanah dan penggunaan atau tutupan lahan. Wilayah Gresik Selatan merupakan daerah periphery Kota Surabaya tertutama untuk bidang perumahan. Tujuan penelitian ini adalah menganalisis tingkat kerentanan banjir berdasarkan tingkat urban sprawl dengan menggunakan metode skoring, overlay dan crastabulation. Metode pengumpulan data dilakukan melalui survei instansi. Hasil penelitian menunjukkan bahwa wilayah Gresik Selatan 56,6% sangat rentan terhadap banjir yang terdiri atas 3,3% urban sprawl rendah, 36,1% urban sprawl sedang dan 17,2% urban sprawl tinggi. Urban sprawl di wilayah Gresik Selatan tidak bisa dicegah tetapi pemerintah perlu antisipasi dampaknya terhadap lingkungan, lalu lintas, sosial dan ekonomi.Abstract: Flood prone areas are areas with high potential for flooding. Flood susceptibility can be determined based on rainfall, slope, soil structure and land use or cover. South Gresik Region is the periphery of Surabaya City especially in the housing sector. The purpose of this study is to analyze the level of flood vulnerability based on the level of urban sprawl by using scoring, overlay and crastabulation methods. The method of data collection is done through agency surveys. The results showed that 56.6% of South Gresik area was very vulnerable to flooding which consisted of 3.3% low urban sprawl, 36.1% medium urban sprawl and 17.2% high urban sprawl. Urban sprawl in the South Gresik region cannot be prevented but the government needs to anticipate its impact on the environment, traffic, social and economy.

Abstract After the 2004 tsunami, Banda Aceh experienced rapid urbanization to the south and east of the city as the city grew further away from the coastline. As a result, the urban area grew beyond the city boundary into Aceh Besar Regency, especially in Darul Imarah and Ingin Jaya sub-districts. Hence, these sub-districts experienced rapid development, characterized by extensive conversion of agricultural land into built-up areas. Therefore, uncontrolled development in peri-urban areas will lead to urban sprawl causing negative environmental, economic, and social impacts. This study aims to study the level of urban sprawl and examine the urban growth pattern in peri-urban areas, focusing on Darul Imarah and Ingin Jaya sub-districts. This research used scoring analysis and spatial analysis. First, Maximum Likelihood Classification (MLC) was used to identify built-up areas in 2005 and 2020. Then, the urban growth pattern was analyzed using Landscape Expansion Index (LEI). The classification of urban sprawl was analyzed using five variables: population density, building density, distance to the city center, development within reach of road network, and leapfrog development patterns. The results showed that 33 villages (40%) in the study area were identified as sprawl. In addition, seven villages (21.2%) were classified as high-level urban sprawl, nine villages (27.3%) as medium level, and 17 villages (51.5%) as low level. Urban sprawl development was dominated by the ribbon development pattern (49.6%), concentric pattern 40.8%, and leapfrog pattern 9.6%. The ribbon development occurred along the main road, while the concentric pattern occurred around the current urban subcenter. The urban sprawl has caused negative implications such as higher car ownership and the loss of agricultural land. This research suggests Banda Aceh City and Aceh Besar Regency governments cooperate to control the urban sprawl and its negative impact by establishing a more sustainable urban policy and strengthening regional cooperation.

Urban sprawl and its economic, social, and environmental consequences are central issues for approaching more sustainable forms of life and production. This review provides a broad theoretical exploration of the main features of urban sprawl but also of sustainable urban policies in Western Europe and North America. Urban sprawl can be observed in both continents, as the search for higher standards of economic, social, and environmental sustainability is also an essential feature of urban governance in the last years. Urban sprawl has been slightly weaker in Western Europe, as its are cities generally more compact. Moreover, in Western Europe, urban sprawl has sometimes been confronted with ex-ante preventive policies. However, in North America, urban sprawl from the 1950s has been an essential element of the social ordering and, thus, of the American way of life. In both cases, urban sprawl has generated successive rounds of accumulation of built capital, which is currently managed in sustainable ways essentially through ex-post and palliative measures, that is, trying to “sustain what is unsustainable”. In other words, the idea is to make urban sprawl more sustainable but without altering its main morphological elements.

Full textAbstract:
Urban sprawl and income segregation are two undesired urban patterns that occur during urban development. Empirical studies show that income level and inequality are positively correlated with urban sprawl and income segregation, respectively. However, the relationship between urban sprawl and income segregation is not only rarely investigated but also shows ambiguous empirical results when it is. Therefore, in this study, we built a stylized agent-based model with individual behaviours based on Alonso’s bid rent theory and ran simulations with different combinations of income level and income inequality. We measured the overall emergent patterns with indicators for urban sprawl and income segregation. The model confirms the established positive correlations between income level and urban sprawl and between income inequality and segregation. Furthermore, the model shows a negative correlation between urban sprawl and income segregation under free market conditions. The model indicates that without any policy implementation, a city will either suffer from urban sprawl or income segregation. Thus, this study serves as a starting point to study the effects of different urban planning policies on these two urban problems.

Full textAbstract:
The article explores the relationship between urban sprawl and the urban system. Urban sprawl is not considered to be a static, unsustainable urban form, but rather a dynamic process of urban deconcentration through which the urban structure evolves. After identifying the main characteristics of urban sprawl, this article investigates the connection between urban sprawl and the urban system through the concept of polycentricity. Finally, the two-way relationship between urban sprawl and the urban system is highlighted. Based on the above, an integrated theoretical, conceptual and methodological framework is formulated. A key finding was the emergence of ?small-scale? polycentricity, which implies increasing monocentricity over a wider spatial area. This raises questions over the distinction between the negative phenomenon of urban sprawl and sustainable polycentric forms, and points out a need to review the explanatory devices and theories used in spatial analysis and planning. Empirical evidence was extracted from Thessaloniki?s Influence Area.

Abstract. This study was preceded by the emergence of urban problems, namely the urban sprawl phenomenon. Urban problems such as urban sprawl can have an impact on the environment so that it demands a concept that needs to be applied and prioritized in current development in order to realize sustainable development. Environmental problems are caused by the increasing population growth in urban areas. In addition, there is a need for a study related to the role of stakeholders in efforts to handle urban sprawl in order to determine the extent of the performance of the Bandung City Government in dealing with the impacts arising from this phenomenon. These things motivated the author to conduct a study related to the role of regional apparatus organizations (OPD) in dealing with the impact of urban sprawl in Cibiru District. This study also aims to identify the impact of the urban sprawl phenomenon in Cibiru District, Bandung City and the role of stakeholders in dealing with the impact of the urban sprawl phenomenon in Cibiru District. The analytical method used in this research is descriptive qualitative analysis and MACTOR method. With this method, the impact of the urban sprawl phenomenon in Cibiru District can be identified, namely the emergence of floods and landslides.

Perkembangan Kota Depok menyebabkan perubahan tata guna lahan, dengan munculnya pengembangan sprawl seperti pengembangan pita dan pengembangan leapfrog. Dampak negatif urban sprawl di Kota Depok antara lain kemacetan lalu lintas, banjir, pencemaran udara, dan pencemaran air. Tujuan dari penelitian ini adalah untuk mengetahui hubungan urban sprawl dengan kondisi daya dukung lingkungan pada sektor perairan di Kota Depok. Metode analisis yang digunakan dalam penelitian ini adalah analisis distribusi spasial, autokorelasi spasial, dan korelasi rank Spearman. Temuan penelitian menunjukkan bahwa perkembangan urban sprawl yang terjadi di Kota Depok selama 10 tahun terakhir menunjukkan indikasi tren penurunan urban sprawl, dengan ditemukannya indeks Low Sprawl mendominasi sebesar 84,43% pada periode kedua yaitu tahun 2018 hingga tahun 2023. Namun pada periode tahun 2013 hingga 2018, temuan menunjukkan bahwa kecenderungan Strong Sprawl lebih dominan, cenderung mengarah ke pinggiran kota Depok karena harga tanah yang relatif murah dan belum diterapkannya peraturan zonasi. Lebih lanjut, tipologi urban sprawl yang terjadi mengalami pergeseran dari kecenderungan pengembangan pita menjadi leapfrog sprawl yang berupaya mengisi ruang-ruang kosong akibat pengembangan pita selama periode 2013 hingga 2018. Di sisi lain, perkembangan urban sprawl selama periode tahun 2018 hingga tahun 2023 menunjukkan hubungan yang signifikan terhadap Status Daya Dukung Lingkungan Hidup/D3TLH - Bidang Air Minum, walaupun dengan arah negatif yang lemah. Indikasi tersebut juga menunjukkan bahwa baik non-sprawl, low sprawl, maupun strong sprawl bukanlah faktor penentu utama dan kuat melebihi 81% Status Daya Dukung Lingkungan Hidup/D3TLH - Sektor Air Minum di Kota Depok.

The rapid urbanization has been increasing in mega-cities. It causes many effects in social, economic, or environmental aspect depending on context. The impact on urban development becomes one of visible effects that city planners pay attention to. The planners in U.S. and European cities awakened to initially study urban sprawl phenomenon, as well as a critical situation of haphazard development. Therefore, the urban sprawl theory was originated from western countries’ concept and generally referred in western context. However, this phenomenon occurs not only in western cities but Asian cities also encounter a similar situation. Although sprawl situation is similar in many cities, methodology to measure the extent of sprawl is various based on data source and cause of sprawl in different context that created unique indicators in different study areas. The lacking of earnest sprawl study leads to determination difficulties in urban development of Asian countries. Hence, it is necessary to learn and apply the comprehensive reference study of urban sprawl from western concept.

Abstract Urban sprawl is the development of sparse suburban areas with low population density, limited land use diversity, and poor street connectivity. Numerous studies demonstrated that urban form settings influence indoor and outdoor environments and, consequently, public health in diverse ways. This review aims to assess the association between sprawl and each health outcome evaluated in the literature to better define urban sprawl and its effects on human health. Using the PRISMA statement, this narrative review evaluates the associations between urban sprawl and any health outcome analyzed by researchers seeking to assess a possible relationship. A total of 826 records were identified via PubMed/MEDLINE (227) and Scopus (599) and 36 studies were deemed suitable for inclusion: 21/36 studies (58%) focused on obesity as the primary health outcome, 4/36 (11%) on life expectancy and/or mortality, 7/36 (19%) on accidents or emergency medical service response, and 4/36 (11%) on the self-reported psychological distress and/or physical health conditions associated with urban sprawl. In most studies, there is a general lack of uniformity and urban sprawl is loosely defined, with urban sprawl definitions frequently corresponding to different combinations of items within sprawl indexes. Nonetheless, urban sprawl appeared to be a determinant of health in many of the examined outcomes; therefore, it is necessary to promote alternatives to sprawling patterns when developing urban settings.

Dispersed low-density development–“urban sprawl”–has many detrimental environmental, economic, and social consequences. Sprawl leads to higher greenhouse-gas emissions and poses an increasing threat to the long-term availability of many vital ecosystem services. Therefore, urban sprawl is in stark contradiction to the principles of sustainable land use and to the need for a sustainability transformation. This study presents the degree of urban sprawl on the planet at multiple spatial scales (continents, UN regions, countries, subnational units, and a regular grid) for the period 1990–2014. Urban sprawl increased by 95% in 24 years, almost 4% per year, with built-up areas growing by almost 28 km2 per day, or 1.16 km2 per hour. The results demonstrate that Europe has been the most sprawled and also the most rapidly sprawling continent, by 51% since 1990. At the scale of UN regions, the highest relative increases in urban sprawl were observed in East Asia, Western Africa, and Southeast Asia. Urban sprawl per capita has been highest in Oceania and North America, exhibiting a minor decline since 1990, while it has been increasing rapidly in Europe, by almost 47% since 1990. The study revealed a strong relationship between urban sprawl and the level of human development as measured by the Human Development Index (HDI). The results suggest that it will be important for a more sustainable future to find a better balance between a high quality of life and using land more sparingly. There is an urgent need to stop urban sprawl, since current regulations and measures in developed countries are apparently not effective at limiting it. Monitoring urban sprawl can serve to guide policy development such as the implementation of targets and limits and to evaluate the effectiveness of urban growth management strategies at mitigating urban sprawl.

Urban sprawl does not invariably impede factor agglomeration; rather, it can foster polycentric urban configurations, thereby enhancing productivity and encouraging enterprise innovation. This study investigates the effect of urban sprawl on enterprise innovation using data for A-share listed Chinese companies from 2010 to 2020. The results reveal a significant inverted U-shaped relationship between urban sprawl and enterprise innovation, particularly among large enterprises, well-established entities, non-state-owned enterprises, and those operating in non-manufacturing sectors. Additionally, the effects of urban sprawl on the inverted U-shaped relationship are more pronounced in the north-eastern regions and small cities. Regional integration significantly moderates the inverted U-shaped relationship between urban sprawl and enterprise innovation. This research contributes new insights to the field of enterprise innovation, offering theoretical and empirical support for analyzing the economic implications of urban sprawl.

The issues of urban sprawl are current in both global research as well as the sphere of activities by public authorities in developed and developing countries. Urban sprawl is a phenomenon that goes beyond the administrative boundaries of cities, which forces monitoring of the phenomenon on a wide territorial scale, i.e., regional and national. However, assessing the level of urban sprawl on such a scale still remains a research challenge in many countries. Poland is such an example, where there is a deficit in assessing the level of the phenomenon, its spatial specificity, as well as comparisons between other national urban areas. The presented research uses the urban morphology method to assess urban sprawl in Poland. The method assumes the use of square grids and building locations for the quantification of sprawl. Based on the 14 urban areas that aggregate 296 communes, it was pointed out that the level of urban sprawl in Poland is moderate. The results indicate that there is not a significant sprawl or compact structures.

Full textAbstract:
Based on the panel data of 227 prefecture-level and above cities in China from 2002 to 2018, a panel linkage equation model is constructed to explore the bidirectional influence relationship between haze pollution and urban sprawl, and the results of the study find that, firstly, there is a bidirectional promotion of causality between haze pollution and urban sprawl. That is, PM2.5 not only has a significant positive effect on urban sprawl, but also urban sprawl has a significant positive correlation with haze pollution, which is further strengthened by adding the air flow coefficient instrumental variable. Second, the heterogeneity analysis yields that haze pollution has different effects on urban sprawl in different regions. Under the sub-regional samples, haze pollution and urban sprawl have a bi-directional significant negative impact relationship in the eastern region, none of the haze pollution and urban sprawl have a bi-directional significant impact relationship in the western region, but both the central region and the northeastern region have a significant positive impact relationship. Under different city sizes, haze pollution and urban sprawl in large, medium and small cities have a bi-directional significant positive impact relationship, and from the numerical size, the degree of influence of haze pollution on urban sprawl in large cities is greater than that in small and medium cities; while the degree of influence of urban sprawl on haze pollution in medium cities is greater than that in large and small cities. Accordingly, it is proposed that urban governance should be adapted to local conditions, focus on innovative technologies to reduce energy consumption, and utilize big data to manage cities.

Urban sprawl has caused an impact on urban development, causing land use changes, loss of income and cultural values, environmental degradation, and high monetary costs. Urban sprawl needs to be carried out efficiently and inclusively to ensure sustainable land use and management including cities in Indonesia. Since 1980s, urban sprawl in Indonesia is high due to limited land which causes the expansion of development on the expanse of agricultural areas and coastal settlements. This paper presents a critical review of the parameters of urban sprawl in agricultural cities including Bandung, Batu, Pekanbaru and coastal cities including Surabaya, Gresik, and Madura using the Analytic Hierarchy Process (AHP). The parameters are gathered from a review of articles related to urban sprawl in agricultural and coastal cities in Indonesia. The result of this comparative studies showed two key important variables that caused urban sprawl in Indonesia: population growth, and land limitation to encompass agricultural and coastal cities. Furthermore, there are four priority parameters out of eight, namely immigrant population ratio-transnational, birth ratio, population growth rate, and land occupation ratio causing urban sprawl in agricultural and coastal cities. In sum, the findings of this study suggest the importance of applying urban sprawl parameters in analyzing urban development as it is useful for evaluating and monitoring the rapid urban development in Indonesia.

Full textAbstract:
There are important relationships between the urban sprawl process and economic growth. They are usually expressed through spatial relations and changes taking place in the local, regional and national economy. The temporal and spatial dimension, including dispersed location, are the determinants of development and economic growth. Therefore, the urban sprawl phenomenon and the related location, hypothetically conditioning economic growth, should be subject to macroeconomic research. The article examines how urban sprawl affects the national budget and national economic growth. Unlike many studies where urban sprawl is studied by scattering the population around cities, we undertake more complex examination using buildings’ location. Urban sprawl, as we understand it, is a spontaneous spread of buildings around cities. To assess the spontaneity, we use a grid of squares with a side of 500 m. The squares are used to calculate the morphological indicators of urban sprawl. Therefore, quantified urban sprawl is one side of the equation; on the other side are macroeconomic variables. In this way, we examine the relationship between urban sprawl and the national budget and economic growth of Poland. The conclusions obtained are, e.g., urban sprawl does not have a negative effect on the national economy and the budget. This is a different conclusion from those thus far. There are also different conclusions on the regional level. Based on the research results, we formulate recommendations for national economic policy and spatial policy.

Full textAbstract:
Based on the panel data of 224 prefecture-level and above cities in China from 2003 to 2016, this paper empirically studies the impact of urban sprawl on air pollution and introduces a mediating effect model to test the mediating role of vehicle ownership concerning the impact of urban sprawl on air pollution. The research in this paper arrives at three conclusions. First, urban sprawl has a significant positive effect on air pollution, and this conclusion is still valid after solving the endogeneity problem and conducting a robustness test. Second, the results of mediating effect test show that urban sprawl indirectly affects air pollution through the partial mediating effect of vehicle ownership. By removing the mediating effect, urban sprawl has a significant negative impact on air pollution, indicating that the mediating effect of vehicle ownership is higher concerning the impact of urban sprawl on air pollution. Third, further panel quantile regression results show that the higher the level of air pollution, the weaker the mediating effect of vehicle ownership and the stronger the direct effect of urban sprawl on air pollution. These conclusions can provide some empirical support for solving the air pollution problems caused by urban sprawl in China.
