This paper combined multi-temporal remotely sensed data with landscape indices to investigate urban growth patterns of the Hanoi capital city of Vietnam from 1993 to 2010. Furthermore, the quantitative composition and distribution of the growth types were analyzed during the different periods. Afterwards, the distance effect on urban growth pattern from the center and fringe of urban patches was studied using buffering analysis. Our objectives were to quantify the speed, growth modes, and resultant changes in landscape pattern of urbanization and to examine the diffusion-coalescence and the landscape structural homogenization processes in Hanoi capital city. Cities in Vietnam have been experiencing major urban transition since the country adopted the economic reform in 1986 which introduce liberal market mechanisms, encouraging private-sector initiatives, while retaining the government's role as the nation's strategic planner and enforcer. Hanoi, one of the two largest economic centers, has been experiencing a progressive urbanization during the 17 years between 1993 and 2010. Using gradient approach, our study has shown that the rate of urban growth was higher in between 10 to 35 km buffer zones. The growth modes and landscape structure changes of urbanization were also comprehensively captured and described using the landscape expansion index and selected landscape metrics. The process of urbanization was characterized by relative dominance of infilling, edge expansion, and spontaneous growth modes across the landscape. Our observation of the Hanoi urbanization in 17 year period could support the diffusion and coalescence phase dynamics. In addition, periodicity in the growing process, and the regularities of the shift of growth hot-zone revealed in this paper could be important implications for urban modeling and prediction. Through our landscape pattern analysis and comparison with other cities, it revealed that the urbanization of Hanoi is limited by its infrastructure systems which make the urban growth not evenly distributed, limiting their competitive advantage, disproportionately high transport costs, growing congestion and land market distortions. Therefore, strategic urbanization plan for future should consider improving urban transport and infrastructure systems, as well as strengthening its competitiveness in the region.

This book examines the urban growth trends and patterns of various rapidly growing metropolitan regions in developing Asian and African nations from the perspective of geography. State-of-the-art geospatial tools and techniques, including geographic information system/science and remote sensing, were used to facilitate the analysis. In addition to the empirical results, the methodological approaches employed and discussed in this book showcase the potential of geospatial analysis, e.g. land-change modeling for improving our understanding of the trends and patterns of urban growth in Asia and Africa. Furthermore, given the complexity of the urban growth process across the world, issues raised in this book will contribute to the improvement of future geospatial analysis of urban growth in the developing regions. This book is written for researchers, academicians, practitioners, and graduate students. The inclusion of the origin and brief history of each of the selected metropolitan regions, including the analysis of their urban primacy, spatiotemporal patterns of urban land-use changes, driving forces of urban development, and implications for future sustainable development, makes the book an important reference for various related studies.

Most studies on urbanisation focus on the move of rural people to cities and the impact this has, both on the cities to which the people have moved, and on the rural communities they have left. This book, on the other hand, considers the impact on rural communities of the physical expansion of cities. Based on extensive original research over a long period in one settlement, a rural commune which over the course of the last two decades has become engulfed by Hanoi’s urban spread, the book explores what happens when village people become urbanites or city dwellers – when agriculture is abandoned, population density rises, the value of land increases, people have to make a living in the city, and the dynamics of family life, including gender relations, are profoundly altered. This book charts these developments over time, and sets urbanisation in Vietnam in the wider context of urbanisation in Southeast Asia and Asia more generally.

This book describes a comprehensive framework of novel simulation approaches, conventional urban models, and related data mining techniques that will help develop planning support systems in Beijing as well as other mega-metropolitan areas. It investigates the relationships between human behaviors and spatial patterns in order to simulate activities in an urban space, visualize planning alternatives, and support decision making. The book first explains urban space using geometric patterns, such as points, networks, and polygons, that help identify patterns of household and individual human behavior. Next, it details how novel simulation methodologies, such as cellular automaton and multi-agent systems, and conventional urban modeling, such as spatial interaction models, can be used to identify an optimal or a simulated solution for a better urban form. The book develops a comprehensive land use and transportation integrated model used to explore the spatial patterns of mutual interaction between human mobility and urban space. This model can help forecast the distribution of different types of households, rent prices, and land prices, as well as the distribution of routes and traffic volume based on an appraisal of labor demand and supply. This book shows how geospatial analysis can be a useful tool for planners and decision makers to help in ascertaining patterns of activities and support urban planning. Offering both novel and conventional approaches to urban modeling, it will appeal to researchers, students, and policy makers looking for the optimal way to plan the d evelopment of a mega-metropolitan area.

Vietnam is experiencing one of the greatest urban transitions over the last two decades after the embankment of "Doi Moi" policy in 1986. The urban transition is vividly manifested in social, economic and physical aspects. While the urbanization can boost the industrialization and modernization goals of the country, it can cause adverse impact on natural environment as well as society and economy. To support a sound urban development plan, it is important that data and analysis on urban built-up areas are accurate and timely available. In this study, the Support Vector Machine Classification Algorithm (SVM) was applied to the multi-temporal image stacks of Landsat Thematic Mapper (TM) and Enhanced Thematic Mapper (ETM) from 1993 to 2010 to quantify the changes of built-up areas over three time periods, 1993-2001, 2001-2006, and 2006-2010 and across twelve buffer zones. Our SVM classification algorithm has produced a highly accurate map of land use/land cover change with the overall accuracy of 95%. The study showed that most of the urban expansion occurred in the periods 2001-2006 and 2006-2010. The analysis was strengthened by the analysis of population census and other socio-economic figures. Through out this study, an implicit correlation between the urban growth, the trend of spatial expansion and other relevant geographic and socio-economic factors can be proposed. Result of this study would allow urban planners and decision makers to timely evaluate and adjust accordingly the urban growth and be aware of the sustainable usage of the invaluable natural lands and other environmental, social and economical problems.

Built on 'the bend in the Red River', Hà Nội is among Southeast Asia's most ancient capitals. Over the centuries, it took shape in part from a dense substratum of villages. With the economic liberalisation of the 1980s, it encountered several obstacles to its expansion: absence of a real land market, high population densities, the government's food self-suffciency policy that limits expropriations of land and the water management constraints of this very vulnerable delta. Since the beginning of the new millennium, the change in speed brought about by the state and by property developers in the construction and urban planning of the province-capital poses the problem of integration of in situ urbanised villages, the importance of preserving a green belt around Hà Nội and the necessity of protection from flooding. The harmonious fusion of city and countryside, which has always constituted the Red River Delta's defining feature, appears to be in jeopardy. Working from a rich body of maps and field studies, this collective work reveals how this grass-roots urbanisation encounters 'top-down' urbanisation, or metropolisation. By combining a variety of disciplinary approaches on several different scales, through a study of spatial issues and social dynamics, this atlas not only enables the reader to gauge the impact of major projects on the lives of villages integrated into the city's fabric but also to re-establish the peri-urban village stratum as a fully-fledged actor in the diversity of this emerging metropolis.
