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.
In a rapidly urbanizing and globalized world, cities have been the epicentres of COVID-19 (coronavirus). The virus has spread to virtually all parts of the world; first, among globally connected cities, then through community transmission and from the city to the countryside. This report shows that the intrinsic value of sustainable urbanization can and should be harnessed for the wellbeing of all. It provides evidence and policy analysis of the value of urbanization from an economic, social and environmental perspective. It also explores the role of innovation and technology, local governments, targeted investments and the effective implementation of the New Urban Agenda in fostering the value of sustainable urbanization.
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.
For the first time in history, the majority of the world's population lives in urban areas. Much of this urbanization has been fueled by the rapidly growing cities of the developing world, exemplified most dramatically by booming megacities such as Lagos, Karachi, and Mumbai. In the coming years, as both the number and scale of cities continue to increase, the most important matters of social policy and economic development will necessarily be urban issues. Urbanization, across the world but especially in Asia and Africa, is perhaps the critical issue of the twenty-first century. Global Urbanization surveys essential dimensions of this growth and begins to formulate a global urban agenda for the next half century. Drawing from many disciplines, the contributors tackle issues ranging from how cities can keep up with fast-growing housing needs to the possibilities for public-private partnerships in urban governance. Several essays address the role that cutting-edge technologies such as GIS software, remote sensing, and predictive growth models can play in tracking and forecasting urban growth. Reflecting the central importance of the Global South to twenty-first-century urbanism, the volume includes case studies and examples from China, India, Uganda, Kenya, and Brazil. While the challenges posed by large-scale urbanization are immense, the future of human development requires that we find ways to promote socially inclusive growth, environmental sustainability, and resilient infrastructure. The timely and relevant scholarship assembled in Global Urbanization will be of great interest to scholars and policymakers in demography, geography, urban studies, and international development.
New towns—large, comprehensively planned developments on newly urbanized land—boast a mix of spaces that, in their ideal form, provide opportunities for all of the activities of daily life. From garden cities to science cities, new capitals to large military facilities, hundreds were built in the twentieth century and their approaches to planning and development were influential far beyond the new towns themselves. Although new towns are notoriously difficult to execute and their popularity has waxed and waned, major new town initiatives are increasing around the globe, notably in East Asia, South Asia, and Africa. New Towns for the Twenty-First Century considers the ideals behind new-town development, the practice of building them, and their outcomes. A roster of international and interdisciplinary contributors examines their design, planning, finances, management, governance, quality of life, and sustainability. Case studies provide histories of new towns in the United States, Asia, Africa, and Europe and impart lessons learned from practitioners. The volume identifies opportunities afforded by new towns for confronting future challenges related to climate change, urban population growth, affordable housing, economic development, and quality of life. Featuring inventories of classic new towns, twentieth-century new towns with populations over 30,000, and twenty-first-century new towns, the volume is a valuable resource for governments, policy makers, and real estate developers as well as planners, designers, and educators.

Urbanization is one of the most powerful forces influencing global sustainability. It is dominated by three factors: population growth, rural-urban migration and subsequent urban expansion. Perhaps nowhere are these factors more dominant than in developing countries. This volume brings together leading experts including Alan Gilbert, John Friedmann, Saskia Sassen and Janice Perlman to explore the conflicting challenges of rapid urbanization in developing countries. While all have to contend with key issues such as social segregation, poverty, and loss of governability, the ongoing forces of urban growth vary from country to country. By comparing the challenges of urbanization in Africa, Latin America, Asia and the Pacific, this book puts forward a new way of thinking about mega- and million-cities in developing countries - one that promotes their vital function in society as engines of ideas, technologies, societal change, democratic transformation and loci of political will to build a new regime of global sustainability.
There is increasing appreciation in the social sciences that context is an important element in understanding social, economic, cultural, political and demographic processes. An important element in context is the type of settlement in which people live and work and so, it is vital to be able to categorise people into particular settlements types. This book brings together a leading team of social scientists to present the latest information on urbanization around the world, highlighting examples of development patterns that are not adequately captured by the UN's type of reporting systems and drawing attention to other ways of representing current trends.
The city in the twenty-first century faces major challenges, including social and economic stratification, wasteful consumption of resources, transportation congestion, and environmental degradation. More than half of the world’s population lives in cities and major metropolitan areas, and in the next two decades the number of city dwellers is estimated to reach five billion. This puts enormous pressures on transportation systems, housing stock, and infrastructure such as energy, waste, and water, which directly influences the emissions of greenhouse gases. As the long emergency awaits us, urgent questions remain: How will our cities survive? How can we combat and reconcile urban growth with sustainable use of resources for future generations to thrive? Where and how urbanism comes into the picture and what “sustainable” urban forms can do in light of these events are some of the issues Sustainable Urbanism and Beyond explores. With more than sixty essays, including contributions by Andrés Duany, Saskia Sassen, Peter Newman, Douglas Farr, Henry Cisneros, Peter Hall, Sharon Zukin, Peter Eisenman, and others, this book is a unique perspective on architecture, urban planning, environmental and urban design, exploring ways for raising quality of life and the standard of living in a new modern era by creating better and more viable places to live.
