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.

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.

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.

This book unifies housing policy by integrating industrialized and developing-country interventions in the housing sector into a comprehensive global framework. One hundred indicators are used to compare housing policies and conditions in 53 countries. Statistical analysis confirms that--after accounting for economic development--enabling housing policies result in improved housing conditions.

Nearly 4,000 cities on our planet today have populations of 100,000 people or more. We know their names, locations, and approximate populations from maps and other data sources, but there is little comparable knowledge about all these cities, and none that can be described as rigorously scientific. The Planet of Cities together with its companion volume, the Atlas of Urban Expansion, contributes to developing a science of cities based on studying all these cities together—not in the abstract, but with a view to preparing them for their coming expansion. The book puts into question the main tenets of the familiar Containment Paradigm, also known as smart growth, urban growth management, or compact city, that is designed to contain boundless urban expansion, typically decried as sprawl. It examines this paradigm in a broader global perspective and shows it to be deficient and practically useless in addressing the central questions now facing expanding cities outside the United States and Europe. In its place Shlomo Angel proposes to revive an alternative Making Room Paradigm that seeks to come to terms with the expected expansion of cities, particularly in the rapidly urbanizing countries in Asia and Africa, and to make the minimally necessary preparations for such expansion instead of seeking to contain it. This paradigm is predicated on four propositions:1. The expansion of cities that urban population growth entails cannot be contained. Instead we must make adequate room to accommodate it.2. City densities must remain within a sustainable range. If density is too low, it must be allowed to increase, and if it is too high, it must be allowed to decline.3. Strict containment of urban expansion destroys the homes of the poor and puts new housing out of reach for most people. Decent housing for all can be ensured only if urban land is in ample supply.4. As cities expand, the necessary land for public streets, public infrastructure networks, and public open spaces must be secured in advance of development.The first part of the book explores planetary urbanization in a historical and geographical perspective, to establish a global perspective for the study of cities. It confirms that we are in the midst of an urbanization project that started in earnest at the beginning of the nineteenth century, has now reached its peak with half the world population residing in urban areas, and will come to a close, possibly by the end of this century, when most people who want to live in cities will have moved there. This realization lends urgency to the call for preparing for urban expansion now, when the urbanization project is still in full swing, rather than later, when it would be too late to make a difference.The second part of the book seeks to deepen our understanding and thus lessen our fear of urban expansion by providing detailed quantitative answers to seven sets of questions regarding the dimensions and attributes of urban expansion:1. What are the extents of urban areas everywhere and how fast are they expanding over time?2. How dense are these urban areas and how are urban densities changing over time?3. How centralized are the residences and workplaces in cities and do they tend to disperse to the periphery over time? 4. How fragmented are the built-up areas of cities and how are levels of fragmentation changing over time?5. How compact are the shapes of urban footprints and how are their levels of compactness changing over time?6. How much land would urban areas require in future decades?7. How much cultivated land will be consumed by expanding urban areas?By answering these questions and exploring their implications for action, this book provides the conceptual framework, basic empirical data, and practical agenda necessary for the minimal yet meaningful management of the urban expansion process.The companion volume, Atlas of Urban Expansion, was also authored by Lincoln Institute visiting fellow Shlomo “

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.

This book carries out an initial assessment of Nepal s urban growth and spatial transformation, with a focus on spatial demographic and economic trends, economic growth drivers and infrastructure requirements of Nepal s urban regions.
