The population of central Texas is increasing rapidly, and urbanization and suburban development continue amid projections of unprecedented growth to come. How is this affecting the expanses of rich agricultural land and remaining scraps of Blackland Prairie upon which the agricultural industry of east central Texas was built? State Highway 130 is partially complete – providing an urban-area bypass intended to alleviate traffic on I35 between San Marcos and Georgetown. In view of the building of this new transit and development corridor to the east of I35, on the eastern edge of Austin, what can be done to preserve agriculture and native prairie on Austin’s urban fringe? In this PR, I examine this question in terms of two essential components: growth management and land conservation. There are numerous studies on the structures and efficacies of growth management tools and of land conservation strategies, but there is little discussion of the role of growth management in relation specifically to urban and urban-fringe agriculture. I begin with a literature review, surveying the current state of study and practice with regard to growth management and open space & agricultural land conservation. This is followed by a case study of state-level open space conservation policy in Georgia, from which I draw lessons relevant to my case. The next step is to frame the potential management and conservation policies presented win the literature review and case study within the context of local practices, thus narrowing the focus of analysis to the confines of my study area: an approximately 20-mile wide, 58-mile long corridor along a portion of SH130. To gauge the possibilities for management and conservation within the study area, I have produced a matrix of jurisdictions and policy options, and an inventory of vacant land. Using the matrix I analyze, on the one hand, the relevant legal codes available to each jurisdiction, and on the other hand, local attitudes toward growth and agriculture. The land inventory is a graphic presentation – through GIS mapping – of factors critical to the potential preservation of open space. The final operation is to sketch a larger proposal within which this study would fit as a preliminary step. Here I suggest an implementation plan, based on the Envision Central Texas model, and recommend directions for future research. / text

Hong Kong’s extremely high density has mesmerised many outsiders for years. Through the devastations of the World War II to the influx of immigration from the Mainland China, Hong Kong has managed to build a remarkable city within the severely limited land mass and inhospitable topography. Hong Kong’s skyscrapers sores into the sky, leaving crevasses of spaces between towers for people and vehicles to flow through. In the Central Business District, elevated walkway connections hovers and criss-crosses every major roads, moving thousands of people on a daily bases. Some people descend into the CBD by hopping on hill-side escalator from nearby residential area of Mid-Levels. Seemingly chaotic yet orderly typical scene of Hong Kong’s CBD is enough to intimidate first timers to Hong Kong. Add flying cars and people in futuristic suits, it will be enough to resemble those images of future envisaged by film makers and architects from the early 20th century. The vertical city of Hong Kong has emerged as one of the first embryonic volumetric cities in the world. Hong Kong continues to defy the conventional Western beliefs in urban planning and development establishing itself as an efficient, vibrant and safe urban model with an extreme density. Yet, the city’s experience remains peripheral to the mainstream debates despite many lessons to be learned from Hong Kong as more cities aspire to intensify in an attempt to establish sustainable living. The reasons for this can be attributed to the general lack of evidence-based research on Hong Kong’s model, especially in vertical urbanism, as well as the reluctance to adapt higher density living in the West, shrouded by grossly misunderstood notions of density. This research begins by demystifying the (mis)understandings of density using Hong Kong as an example and attempts to decode the complexity of Hong Kong’s urban model. The research does this by developing and applying a quantifiable tool – the Volumetric Study - to assess and analyse the current practice of building in Hong Kong and to identify the emerging condition of multiple ground. The complexities of vertical and/or volumetric living are assessed using readily available data and simple field work. It is hoped that the Volumetric Study offers insight into the understanding of how existing buildings operate as well as providing potential guidance for future improvements and development. / published_or_final_version / Architecture / Doctoral / Doctor of Philosophy

The study explores the relationship between lineage, social capital and in situ urbanization of “villages within city” in the context of China’s rapid urban expansion. The literature reviewed shows that there have been studies on many aspects of “villages within city” since the middle 1990s. However, the role of lineages during the in situ urbanization of “villages within city” is largely under-examined and remains as a research gap. This study endeavors to fill this cross-disciplinary gap. Taking notice of the differences between single-lineage “villages within city” and multi-lineage ones, the study explores the following two research questions: (1) does the level of social capital vary among “villages within city” with different lineage structures? If yes, in what way? (2) does social capital in “villages within city” influence the outcomes of urbanization? If yes, what role does it play? In order to address the above research questions, the study firstly consults three areas of study, namely, lineage, social capital and in situ urbanization of “villages within city”. Through examining the relationships among the three key research variables, the thesis demonstrates the significance of theoretical integration of the three concepts and develops a tentative analytical framework. Given the different lineage structures, it is hypothesized that single-lineage “villages within city”, compared with multi-lineage ones, are more likely to possess higher levels of social capital at the administrative village level, and thus could achieve better outcomes of urbanization. To test the hypotheses, two representative “villages within city” with different lineage structures in Futian district of Shenzhen — the single-lineage Xiasha administrative village (including six natural villages which are lived by six Huang sub-lineages) and the multi-lineage Shawei administrative village (including three natural villages that are inhabited by different lineages of Wen, Mo and Liang) — are selected as the case study sites after examining the development trajectory of villages and lineages in Shenzhen. The empirical study measures the levels of social capital in Xiasha and Shawei at both the natural village level and administrative village level through the use of a questionnaire survey, and examines the outcomes of urbanization of Xiasha and Shawei through literature review, department interview, site study and observation. Three major findings are identified through analyzing the case study: (1) lineage structures in some Chinese “villages within city” are institutional legacies of rural collectivization in the late 1950s; (2) there exists a higher level of social capital at the administrative village level in single-lineage “village within city” than that in multi-lineage one; (3) social capital at the administrative village level, other than that at the natural village level, has a positive role in promoting in situ urbanization of “villages within city” in terms of collective economy development, physical environment construction and lineage culture reservation. / published_or_final_version / Urban Planning and Design / Doctoral / Doctor of Philosophy

This project examines the Baixada Fluminense (or simply the Baixada), in metropolitan Rio. It specifically analyzes how rapid urbanization affected political and social change during Brazil's reasonably democratic 1945-1964 period. More specifically, I analyze how local-level populist politics, the accelerated social transformation resulting from industrialization, urbanization, violence, the press, and changes in the countryside not only affected the areas residents, but reflected trends, transformations, and major shifts on the national level as well as in Latin America as a whole. In effect, I argue that national issues became local issues, and vice-versa. This project, through a close textual analysis of both archival and printed sources, analyzes the political career of Tenório Cavalcanti, the region's dominant politician and strongman (known as the "Man in the Black Cape") as a an entry point into various aspects political and social climates on both the local and national levels. The Baixada, previously an agricultural area, became a center of industry with a population of nearly one million by 1960. The new arrivals to the Baixada included impoverished migrants from the countryside as well many of the urban poor from nearby Rio de Janeiro who sought both employment and living accommodations within their financial means. Tenório, whose career as a populist politician spanned this entire period, reflected the demographic, social and political changes in his electorate. His gradual shift from right to left (as a result of an increasingly radical and organized lower class constituency in both the city and the countryside) exemplified this phenomenon. I also challenge the notion of the "Populist Republic"- the nickname commonly given to the 1945-1964 period. By fully acknowledging that populism existed on a large scale, and that it is generally viewed in a negative light from both the left and the right, I argue that many of the problems of the democratic period (and the populist politics that dominated the era) resulted as much from systemic limitations and an incomplete transition to democracy as it did from corruption and demagoguery (by-products of these very limitations).

Several factors influence the social participation of rural migrants in urban structures according to previous studies: (1) origins, (2) education, (3) occupation, (4) auspices of migration, (5) age at migration, (6) length of residence, (7) previous migrations, (8) social mobility, (9) income, (10) geographic mobility, (11) community activities. These variables will be included in the research design of this present study. Review of previous studies indicates that there have not been any studies conducted on the factors associated with urban church participation of former members of rural churches.

Due to the inappropriate planning and explosive population growth in urban areas, especially in developing countries, sustainable and disaster-safe urbanization has become the most important challenge for governments. Urbanization presents benefits in different ways but has led simultaneously to changes in land use/land cover (LULC), impacting soil quality, runoff, surface temperature, water quality, and promoting climate change. The environmental implications of LULC changes cannot be understood well enough to take precautions without the knowledge of LULC change. This reality is the driving force behind my research, which focuses on impacts of urbanization on flood and soil erosion hazards in Istanbul, Turkey. Istanbul is the biggest city in Turkey with its almost 15.000.000 population. In 1999 the Marmara earthquake destroyed the city especially the newly developed zones. Every year Istanbul suffers also from flood damages. Istanbul has been experiencing uncontrolled migration, chiefly from rural areas, since the economic reform policies took place in the second half of the 20th century. These policies forced the city to expand towards the agricultural land and to the coastal areas. Istanbul has been faced with illegal housing and uncontrolled development since then. This development has produced significant decreases inproductive agricultural lands and created more impervious areas. Infrastructure development has not matched the rate of the population increase and uncontrolled urbanization, making the city vulnerable increasingly to natural disasters. This dissertation aims to understand the impacts of urbanization on flood and erosion hazards in Istanbul by examining changes in the city using remote sensing (RS) and geographical information systems (GIS) methods. LULC was examined first: Two change detection methods were applied to choose the best performer for Istanbul. The post-classification comparison (PCC) method produced better results than the principal component analysis (PCA). PCC utilized 1984, 1997, 2001, 2007 and 2010 Landsat images of the study area. These Landsat images were corrected atmospherically and radiometrically using COST Model (Markham and Barker, 1986). After the corrections geometric rectification was performed with the help of 1987 topographic map, 1995 orthophotos, 2005 GPS data. Location and nature of the change were derived for the time periods. Results show that since 1984, agricultural land have been replaced increasingly by urbanization. Flooding and related soil erosion are both natural events. Yet these events can be hazardous; they can harm/destroy lives and property. In recent years these events have become disasters for Istanbul. We investigated the role of urban growth in such disasters. To understand the urbanization and flood relation better, flood events for each time period were examined using LULC change, runoff information and watershed analysis. Soil erosion events occur slowly and in Istanbul they do not happen frequently (yearly) as with flooding. But some of the locations of erosion that occurred in the past are now urbanized areas. It is thus important to understand how the built environment affects soil erosion. We applied the Revised Universal Soil Loss Equation (RUSLE) method for each year in the time series. Prior erosion locations digitized from General Directorate of Mineral Research and Exploration were compared to predicted locations. The resultant maps indicates that European side of Istanbul is more prone to erosion than Anatolian side.
