This study uses satellite imagery and population data for the decade 2000 to 2010 in order to map urban areas and populations across the entire East Asia region, identifying 869 urban areas with populations over 100,000, allowing us for the first time to understand patterns in urbanization in East Asia.
The study of the evolution of an urban system raises a number of practical questions, as to the operational definition of the components of the system as well as to the incorporation of the factor time in the analysis. In this chapter the fo cuss is on the urban centres, the nodes of the urban system. One of the first pro blems to be solved now is the definition of such a node. It has been argued above that population size can be used as an approximation of the complexity of the spatial economic structure of a region. The acceptation of this notion makes it possible to study the urban system as a population system. The analysis of the population system over the study period will be pursued from this perspective. The study period, 1840-1970, covers completely the industrialization and urbanization phase which occurred during the industrial revolution. Over this period the spatial organizational structure of society evolved from a rural-commercial to wards a modern urban-industrial state. One of the major events in this period of change is the spatial redistribution of the population and the population growth. This process will be examined below at three levels of aggregation: (I) the popu lation distribution as one frequency distribution, (2) the population distribution dis aggregated into a n~ber of size classes, and (3) the individual cities which make up the population distribution.
Examines the trends, challenges, issues, and strategies developing countries evaluate when facing a population upsurge and expeditious development of urban environments. The volume explores the use of different governance techniques, trending patterns in urbanization and population growth, as well as tools and the appropriate allocation of resources used to address these issues.
World human population is expected to reach upwards of 9 billion by 2050 and then level off over the next half-century. How can the transition to a stabilizing population also be a transition to sustainability? How can science and technology help to ensure that human needs are met while the planet's environment is nurtured and restored? Our Common Journey examines these momentous questions to draw strategic connections between scientific research, technological development, and societies' efforts to achieve environmentally sustainable improvements in human well being. The book argues that societies should approach sustainable development not as a destination but as an ongoing, adaptive learning process. Speaking to the next two generations, it proposes a strategy for using scientific and technical knowledge to better inform future action in the areas of fertility reduction, urban systems, agricultural production, energy and materials use, ecosystem restoration and biodiversity conservation, and suggests an approach for building a new research agenda for sustainability science. Our Common Journey documents large-scale historical currents of social and environmental change and reviews methods for "what if" analysis of possible future development pathways and their implications for sustainability. The book also identifies the greatest threats to sustainabilityâ€"in areas such as human settlements, agriculture, industry, and energyâ€"and explores the most promising opportunities for circumventing or mitigating these threats. It goes on to discuss what indicators of change, from children's birth-weights to atmosphere chemistry, will be most useful in monitoring a transition to sustainability.
Cities are not only home to around half of the global population but also major centers of economic activity and innovation. Yet, so far there has been no consensus of what a city really is. Substantial differences in the way cities, metropolitan, urban, and rural areas are defined across countries hinder robust international comparisons and an accurate monitoring of SDGs. The report Cities in the World: A New Perspective on Urbanisation addresses this void and provides new insights on urbanisation by applying for the first time two new definitions of human settlements to the entire globe: the Degree of Urbanisation and the Functional Urban Area.
This book provides a unique synthesis of concepts and tools to examine natural resource, socio-economic, legal, policy and institutional issues that are important for managing urban growth into the future. The book will particularly help the reader to understand the current issues and challenges and develop strategies and practices to cope with future pressures of urbanisation and peri-urban land, water and energy use challenges. In particular, the book will help the reader to discover underlying principles for the planning of future cities and peri-urban regions in relation to: (i) Balanced urban development policies and institutions for future cities; (ii) Understanding the effects of land use change, population increase, and water demand on the liveability of cities; (iii) Long-term planning needs and transdisciplinary approaches to ensure the secured future for generations ahead; and (iv) Strategies to adapt the cities and land, water and energy uses for viable and liveable cities. There are growing concerns about water, food security and sustainability with increased urbanisation worldwide. For cities to be liveable and sustainable into the future there is a need to maintain the natural resource base and the ecosystem services in the peri-urban areas surrounding cities. This need is increasing under the looming spectre of global warming and climate change. This book will be of interest to policy makers, urban planners, researchers, post-graduate students in urban planning, environmental and water resources management, and managers in municipal councils.
This anthology of research is divided into five sections: definition of the urban system, structural characteristics, distribution of urban growth, transportation networks and interaction between cities, and the impact of growth on urban behaviour and the rural economy. Each section is preceded by the editors' comments. This is an excellent general reference on urbanization in Canada; it complements existing and largely American-based texts and should stimulate the student's interest in research on the unique Canadian urban milieu.

This book investigates how the state intervenes in the urban system in China in the post-reform period. To do so, it constructs a conceptual framework based on the perspective of political hierarchy, suggesting that the state power is hierarchically organized in China’s urban system, leading to variations in urban government capacities among cities. The book reveals that the state has largely achieved the goal of its national urban system policy to “strictly control the scale of large cities” resulting in the under-development of the large cities if they are mainly developing according to the market force. However, this has become less influential with the advances toward a market economy. Further, state regulation and policies have reduced the gaps between cities at the top and bottom of the urban hierarchy. The book argues that the Urban Administrative System (UAS) is an important tool for the state to regulate urban system development, and the administrative level has a significant effect on urban growth performance. It contends that China’s urban system is strongly shaped by the omnipresent state through the UAS, which hierarchically differentiates between the urban growth processes. By controlling the administrative-level upgrading process, the state can prevent the size and number of cities from increasing too rapidly. This theoretical and empirical enquiry highlights the fact that the hierarchical power relations among cities and the resulting variations in urban government capacities are the key to understanding the role of the state in China’s urban system development in the post-reform period.
The report presents findings from the 2018 revision of World Urbanization Prospects, which contains the latest estimates of the urban and rural populations or areas from 1950 to 2018 and projections to 2050, as well as estimates of population size from 1950 to 2018 and projections to 2030 for all urban agglomerations with 300,000 inhabitants or more in 2018. The world urban population is at an all-time high, and the share of urban dwellers, is projected to represent two thirds of the global population in 2050. Continued urbanization will bring new opportunities and challenges for sustainable development.
In this major new work of urban geography, Allan Pred interprets the process by which major cities grew and the entire city-system of the United States developed during the antebellum decades. The book focuses on the availability and distribution of crucial economic information. For as cities developed, this information helped determine the new urban areas in which business opportunities could be exploited and productive innovations implemented. Pred places this original approach to urbanization in the context of earlier, more conventional studies, and he supports his view by a wealth of evidence regarding the flow of commodities between major cities. He also draws on an analysis of newspaper circulation, postal services, business travel, and telegraph usage. Pred's book goes far beyond the usual "biographies" of individual cities or the specialized studies of urban life. It offers a large and fascinating view of the way an entire city-system was put together and made to function. Indeed, by providing the first full account of these two decades of American urbanization, Pred has supplied a vital and hitherto missing link in the history of the United States.
