This paper uses a typology of local metropolitan development to exam ine population redistribution trends in the US over the past three decades. Theories of system ic maturation and urban life-cyc les are discussed and evaluated. Analysis of population and inter-county migration data reveals that localise d deconcentration has become an increasin gly common sub-process of metropolitan isation ,...

INTRODUCTION Most US studies on asthma prevalence have been conducted in urban areas, and few have assessed the prevalence of asthma among residents of rural areas versus urban areas. The objective of this study was to compare the prevalence of asthma among adults living in metropolitan versus nonmetropolitan counties in Montana. METHODS We analyzed data from 6,846 adult Montanans who complet...

Chinese cities are experiencing rapid urban expansion and being transformed into more dispersed urban form which necessitate the quantification of fine-scale intra-urban characteristics for sustainable urban development. We propose an integrated multi-level and multi-dimensional method to characterize urban sprawl and apply it to Wuhan, a typical metropolitan area in central China from 1996 to ...

Moving beyond a rhythmanalysis approach to banal mobilities and diurnal journey making – commuting, visiting, shopping, leisure this paper explores how place-dependent forms of transport shape the feel flow city. Theorizing city as polyrhythmic reveals multiple traces local/global past/present in socio-historically situatedness urban mobilities. Based on 20 months ethnographic fieldwork Ho Chi ...

Roads provide humans with a means of mobility between destinations, be it for transportation of goods and services or as a means of connecting with others. However, roads are also known to contribute toward a number of deleterious landscape processes, such as habitat destruction and fragmentation, pollution (e.g., chemical, noise and light) and animal mortality. Few studies however have investi...

Peri-urban areas are typically associated with high growth regions that have witnessed rapid landscape changes on the peripheries of metropolitan and urban areas with a particular focus on high amenity areas. These former rural lands adjacent to the edges of urban areas into which they would typically expands or influences have been described as peri-urban areas (‘peri’: around, about or beyond...

Roads are significant objects of an infrastructure and the extraction of roads from aerial and satellite images are important for different applications such as automated map generation and change detection. Roads are also important to detect other structures such as buildings and urban areas. In this paper, the road extraction approach is based on Active Contour Models for 1-meter resolution g...

Identifying the factors that influence the spread of exotic species is essential for evaluating the present and future extent of plant invasions and for the development of eradication programs. We randomly established a network of 250 plots on an exotic Pinus radiata D. Don plantation on Tenerife Island in order to determine if roads and urban centers are favouring the spread of exotic plant sp...
