In recent years considerable progress has been made in the understanding of urban land-use change and its dynamic interrelationships with economic, social, environmental systems. From a quantitative perspective, advancements GIS technologies, increased availability high-resolution remote sensing data, new GIS-based spatial metrics form growth have helped to establish methods for comparative analysis. However, due lack homogeneous very few empirical studies systematically addressed...
During the 1990s, phenomenon of urban sprawl received growing attention in international planning debate. However, a survey literature yields no agreement terms defining and measuring sprawl. The absence common understanding constrains analysis sprawl's causes, costs non-monetary consequences as well formulation strategies towards economically, ecologically socially acceptable land use patterns. On this background, we present an indicator-based framework for measurement assessment...
In modern Western societies people often lead inactive and sedentary lifestyles, even though there is no doubt that physical activity health are related. From an urban planning point of view it would be highly desirable to develop built environments in a way supports leading more active healthy lifestyles. Within this context several methods, predominantly used the US, measure suitability for walking cycling. Empirical studies show living walkable areas physically (for example, walk or cycle...
Urban density must be considered a key concept in the description of city’s urban spatial structure. Countless studies have provided evidence close relationship between built and activity densities, on one hand, environmental conditions or social practices, other hand. However, despite concept’s common use research, is rather fuzzy highly complex that accompanied by confusing variety indicators measurement approaches. To date, an internationally-accepted standard for implementation permits...
This paper presents a land-use change analysis of five Central and Eastern European (CEE) countries. We utilize CORINE (Coordination Information on the Environment) Land-Cover Urban Audit data for two distinct time periods: 1990–2000 2000–2006 aggregated at urban, suburban non-metropolitan geographies. The literature post-socialist cities suggests that urbanization rates patterns in period are quite variable divergent, both "inter"nationally "intra"-nationally, we expect to find spatial...
This study aims to characterize urban spatial structure with respect its multidimensionality. Using an encompassing data set of socioeconomic variables, as well variables pertaining the built environment, accessibility and land use, we suggest a quantitatively based (sub-) center typology. The fine-grained scale 1 km2 grid cells permits higher resolution than that used in most previous studies. Our suggested typology is two-layered: "macro layer" on cluster analyses sheds light...
In this paper, we establish a novel multistep procedure for morphologic characterization of built environments in terms built-up height and density. We rely on elevation measurements from the TanDEM-X mission (TDM) multispectral Sentinel-2 imagery. These earth observation systems feature notable tradeoff between fairly high spatial resolution large-area coverage and, thus, allow spatially continuous analysis around globe. To purpose, follow an automated workflow that foresees distinction...
Following decades of urban decline in many European cities, there is now an abundant literature identifying a process reurbanisation, which has also reached secondary including those post-industrialised regions. Reurbanisation umbrella concept involving several related but distinct processes, though its roots spatial cycle models that consider reurbanisation to be specific stage the development Most emerging debate, however, primarily concerned with processes and impacts on core while...
This paper presents a cross-sectional analysis of the urban land use patterns 230 city regions in 34 European countries and an in-depth longitudinal 10 selected regions. The guiding question is whether post-socialist transformation spatial structure Eastern can be interpreted as adaption process to Western-style urbanisation how far ‘mimicry’ has reached. Our empirical approach based on model designed measure binary with respect dispersion. As cities vary pattern size, we calculate...
This paper provides a brief overview of recent developments and debates concerned with suburbanisation in continental Europe. While current discourses urban research practice still focus on processes reurbanisation the gentrification inner-city areas, suburbia continues to exist thrive. Depending definition applied, suburban areas attract large share in-migration employment growth cities developed countries. Given that popular meta-narratives are often spurred by, or refer to, North American...
The empirical research on urban spatial structure and its evolution still lacks comprehensive, longitudinal international comparative perspectives. At this background, paper addresses the change of intra-metropolitan employment patterns by scrutinizing two relatively large representative samples German US American city regions, covering years between 2003 2015. Our analysis reveals strong differences in distribution both countries. In general, metropolitan areas are far more decentralized...
Résumé Les recherches sur les coûts de l’étalement urbain sont menées manière prédominante dans une perspective croissance. La majorité ces visent à montrer que d’importantes économies en infrastructures peuvent être obtenues augmentant densités urbaines et localisant nouvelles activités développement proximité des zones déjà construites. Cependant, nombreuses régions métropolitaines Europe doivent faire face un déclin démographique quasi surplus urbanisées. De plus, le phénomène...
Since the 1980s and 1990s, many metropolitan areas in North America Europe have registered population growth within urban core, driven primarily by younger, better-educated higher-income people – a phenomenon often referred to as 'urban renaissance' or 're-urbanization'. To date, research on this topic has focused socio-spatial implications, especially with type intensity of displacement pressures affecting low-income households. Demographic manifestations rarely been explicitly targeted...
Abstract We examine the impact of foreign migration on regional disparities in population development Germany by analysing spatial patterns and determinants at county level for period 2007–2017. Counterfactual analyses show that international has been major component growth across German regions. However, immigration mainly directed towards large cities highly urbanised areas therefore reinforced existing development. Spatial econometric models nonetheless reveal migrants are not attracted...
Polycentric urban regions have been advocated for, and justified as enhancing both economic growth overall competitiveness while also creating more equitable balanced metropolitan regions. We examine the role of regional polycentricity in effectuating certain desirable outcomes, specifically productivity minimizing spatial disparities simultaneously German ( Großstadtregionen) a case study. Using econometric analysis functional morphological measures, our results indicate that polycentric...
In recent years, land prices in Germany have skyrocketed to levels that were hardly thought possible. This has particularly affected prospering cities, where price increases of more than 100 % often been recorded since the turn millennium. The underlying causes are highly controversial. While some scholars point scarcity developable due regulatory restrictions, others see “financialization” housing markets wake financial crisis and massive influx liquid capital into as decisive driver....
Measuring spatial patterns is a crucial task in sciences. Multiple indicators have been developed to measure quantitative manner. However, most comparative studies rely on relative comparisons, limiting their explanatory power specific case studies. Motivated by advancements earth observation providing unprecedented resolutions of settlement patterns, this paper suggests measurement technique for overcome the limits comparisons. We design model spanning feature space based two metrics –...
Despite a highly organized and institutionalized planning framework, regions in Germany are widely considered the most variable experimental layer of vary quite extensively terms their organizational composition, strategic purpose, administrative competencies. This research examines role German regional-level explaining urban spatial structure development patterns. Our unit analysis consists 114 Germany. We model change density over 2 time periods as product number demographic, geographic,...
The conversion of open space to built land is a key feature urban-rural transformations. In many countries, urban sprawl represents the dominant mode growth. Against this background, growth management plays crucial role in mediating between diverse spatial requirements and curbing sprawl-like land-use patterns, but its effectiveness not fully understood. Relatively few studies have systematically addressed goals growth-management approaches, their implementation pathways outcomes. Most...

The absence common understanding constrains analysis sprawl's causes, costs consequences, as well formulation strategies towards economically, ecologically socially acceptable land use patterns. Politicians planners aiming to contain must agree upon definition method for progress order track their...
Despite the long tradition of planning to manage urban growth in National Capital Region (NCR) Delhi, region is often criticized by scholars for facing severe problems caused not only an increasing population but also a lack infrastructure provision coupled with outward spatial expansion. Identification development stages provides policy makers tool devise reforms order effectively and efficiently growth. In this article, taking NCR-Delhi as case study using model conceptualized Klaassen–van...
