In recent decades, some cities have seen their urban centers lose population density, as residents spread farther out to suburbs and exurbs. Others have kept populous downtowns even as their environs have grown. Population density in general has economic advantages, so one might wonder whether a loss of density, which may be a symptom of negative economic shocks, could amplify those shocks. We look at four decades of census data and show that growing cities have maintained dense urban centers, while shrinking cities have not. There are reasons to think that loss of population density at the core of the city could be particularly damaging to productivity. If this is the case, there could be productivity gains from policies aimed at reversing that trend.

Theories of the urban growth machine have long been a central analytical tool for contemporary research on urban governance. But in what sense are growth machines, in fact, “urban”? To what degree must “the city” serve as the spatial locus for growth machine strategies? To address such questions, this chapter critically evaluates the influential work of urban sociologists John Logan and Harvey Molotch on US growth machine dynamics. In contrast to an influential line of critique that reproaches these authors for their putative methodological localism, it is argued that their framework is, in fact, explicitly attuned to the role of interscalar politico-institutional relays in the construction of urban growth machines. These considerations lead to a dynamically multiscalar reading of the national institutional frameworks that have facilitated the formation of growth machines at the urban scale during the course of US territorial development. This analysis has broad methodological implications for the comparative-historical investigation of urban governance.

Urban metropolitan city-centers offer the most complex, socially connective environments in the built world. The social structures fundamentally embedded in city life are, however increasingly being overshadowed by an isolating system of city densification. The City of Toronto, as a territory of exploration, is one of many cities that are evolving a dense array of restrictive boundaries that increasingly challenge human connectivity, and the deep-rooted ability of these environments to establish vibrant city life. It is the role of architecture to mediate the relationships between the public and private territories and to understand how these environments are utilized and engaged by the surrounding context. This thesis has extracted critical environmental components exemplified in city, community, and building territories, and has re-integrated these defining characteristics into an alternative design strategy that establishes a balanced symbiotic relationship between the private and public realms of Toronto’s future City Core.

This work deals with the development of urban growth scenarios and the prevision of the spatial distribution of built-up area and population for the urban area of the city of Guangzhou in China. Using freely-available data, including remotely sensed data as well as census data from the ground, expenditure of time and costs shall remain low. Guangzhou, one of the biggest cities within the Pearl River Delta, has faced an enormous economic and urban growth during the last three decades. Due to its economical and spatial characteristics it is a promising candidate for urban growth scenarios. The monitoring and prediction of urban growth comprises data of population and give them a spatial representation. The model, originally applied for the Indian city Ahmedabad, is used for urban growth scenarios. Therefore, transferability and confirmability of the model are evaluated. Challenges that may occur by transferring a model for urban growth from one region to another are discussed. With proposing the use of urban remote sensing and freely available data, urban planners shall be fitted with a comprehensible and simple tool to be able to contribute to the future challenge <i>Smart Growth</i>.

Using the City of Corvallis, Oregon, a small to medium sized American city, as a test-bed, this paper examines the City’s urban growth in relation to urban accessibility. This relationship is explored in an anatomic spatial-temporal fashion, taking account of: the number and size of developed land use parcels over time; urban accessibility from residential to non-residential land use areas; and the statistical relationships between urban form and urban accessibility. This investigation of land use is structured around use-classification and examined within a range of dimensional and demographic measurements over 5-year time periods from 1853 to 2014; concurrently, urban accessibility is measured by the least-cost path distance as calculated through the OD cost matrix analysis in GIS. The results indicate that the city grew spatially at different rates and its urban accessibility experienced both ups and downs over time. The city’s population growth corresponded closely with urban growth and its decreasing population density negatively impacted on the city’s urban accessibility to commerce, industry, and office for most time periods. Significantly, while the urban density increased steadily after 1950s concurrent with an increase in urban sprawl, in contrast to previous studies on the metropolitan condition, the urban density had no evident impact on urban accessibility in Corvallis. Instead, increasing the land-use mix was a more effective and feasible approach to reduce urban travel path distance and enhance accessibility than increasing population density or urban development density. Accordingly, this research provides evidence-based policy recommendations for planning sustainable urban mobility and urban form in small to medium-sized cities.

Robert Venturi has repeatedly noted in several interviews and conversations that his upbringing was as a Quaker. The Quakers (or the Society of Friends) have deep historic ties with the state of Pennsylvania and the city of Philadelphia and have had a significant presence in Venturi’s life. I propose to examine the inconspicuous and largely overlooked intersections between the Quaker aesthetics and beliefs and Venturi’s 1950 thesis project, a Chapel for the Episcopal Academy in Merion, Pennsylvania. «In the world, but not of it», Quakers have situated paradox at the core of their material culture: while the physical world was stripped of metaphysical content, craftsmanship was highly valued; while meetinghouses were never sacred spaces, they have always acted as depositories of historical and cultural genealogies. Through the lens of Quaker doctrine and aesthetics, I will examine the role of paradox in Venturi’s design for the Chapel for the Episcopal Academy.

In a global context, few studies have investigated the effects of urbanization on apifauna, as well as the importance of green areas in urban centers for the conservation of local bee fauna. In Brazil, this line of research is still quite recent, with most studies carried out in regions with a predominance of the Atlantic Rainforest phytogeographic domain. For the Brazilian state of Bahia, such research is still scarce and, especially, if we consider the large territorial dimension that this state denotes. In the area that covers the Cerrado, few studies have been carried out that inventory the urban apifauna. In this paper we present a list of bee species recorded in urban areas of the city of Barreiras, Bahia, Brazil, which represent the first apifauna inventory in the Western region of Bahia. Specimens were collected fortnightly from November 2019 to April 2020, using two sampling methods: colored water traps (ARCAs/pantraps) and entomological net, in two remnants of vegetation used as sampling points. A total of 749 specimens were sampled, distributed in four families, 18 tribes, 29 genera, and 45 species. A total of 369 (49.3%) specimens were collected using the entomological net and 380 specimens (50.7%) by using the ARCAs. Our results showed that the area with the highest level of urbanization had bioindicator species of degraded environments, which benefit from urbanization, and despite the urban growth, the fragments found in the matrix can serve as a refuge for bee fauna, as long as they are well planned.

AbstractNumerous scholars have emphasized the “centrality” of Inner Asia to furthering our understanding of global, or cross-cultural phenomena, and the role of such phenomena in the preservation, modification, and transmission of historical experience. Yet the research has almost exclusively been carried out by specialists in Chinese civilization, and as one moves further away from the Chinese sphere of influence the notion of Eurasia as an integrated socio-political unit of historical analysis becomes more problematic. Here I attempt to bridge the western and eastern edges of the great steppe by focusing on a specific aspect of Inner Asian political culture—the phenomenon of shared sovereignty between military-based ruling dynasties and their urban constituencies—in the principalities of Rus' and the oases of Transoxiana, between the ninth and twelfth centuries. I propose that the dual administrative structure that developed in the two regions was an autochthonic, Eurasian state-formation, distinct from the city-state and imperial models, which emerged as a result of what Joseph Fletcher identified as “horizontal continuities.”

Dar es Salaam is one of the most diverse cities in Tanzania in terms of its physical, social, economic, environmental and spatial features. This diversity has contributed to differences in built-up area, population density, as well as the pace of spatial development across different parts of the city. This study aims to examine the relationship between physical built-up area changes in Dar es Salaam, population density change and spatial development using remote sensing images and census data. The study finds that the city population has grown tremendously, with peri-urban wards in particular having experienced positive growth. Dar es Salam’s built-up area change and urban sprawl emerging at the city’s edges distinctly follows the pattern of demographic change. This is accompanied by substantial compact growth in the inner parts of the city. A number of factors such as transport, residential development, migration, high natural growth rates, public policies and land speculation are found to have contributed to these changes. Overall, the study aims to aid planning authorities in effectively responding to the rapid spatial development taking place in the city, for which a holistic approach that combines an understanding of physical and demographic changes is needed. By investigating the changing patterns in land use within this highly urbanizing city, it aims to generate insights into urban development control machineries and identify their underlying dynamics.
