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.

Chapter 1. World Urbanization: The Critical Issue of the Twenty-First Century

In 2010, a majority of the world’s population lived in cities, an important milestone actually reached in 2008; by 2050, this proportion will approach 70 percent. These simple facts point in two directions: looking back, they confirm the intensity with which the world has urbanized over the past fifty years and, moving forward, they mark the world’s cities as...

The decade ending in 2010 spanned three unique, important transitions in the history of humankind. Before 2000, young people always outnumbered old people. From 2000 forward, old people will outnumber young people. Until approximately 2007, rural people always outnumbered urban people. From approximately 2007 forward, urban...

It took the development community two decades, if not more, to come to terms with the unprecedented urban growth rates that occurred in the developing world between 1950 and 2005 (figure 3.1). The dramatic increase in the proportion of urban population—from 17 percent to 26 percent—that took place between 1950 and 1975 was the first sign that...
Chapter 4. Urban Growth and Development at Six Scales: An Economist’s View

The world’s population, roughly 6.7 billion people, spreads over about 13 billion hectares of land. (Of course, much of this land is arid or otherwise inhospitable to settlement, but more on that later.) Variously considered, people live in nations, regions, cities, and neighborhoods. The study of their urbanization is, more or less, the study of density as...

China has experienced rapid urban growth since the adoption of Economic Reform and Open Policy in 1978. Not only is more than one-third of the country’s population now living in cities, but the remaining population is becoming increasingly dependent on cities and towns for its economic survival and livelihood. At the National People’s Congress...

From the perspective of global urbanization, the first decade of the twenty-first century will be seen not as the time when the problems associated with urbanization first became apparent (these have been widely understood since the nineteenth century and perhaps earlier), nor as the time when the basic outlines of policy solutions first attained wide-...
Chapter 8. Urban Growth Models: State of the Art and Prospects
Download PDF (161.7 KB)
Once known as urban activity models, urban growth models (UGMs) emerged in the mid-1960s out of advances in regional science, huge improvements in computing speed and storage capacity (or so they seemed at the time), a newfound surplus of detailed activity data, and federal mandates coupled with funding for metropolitan planning...

Bertrand Renaud (1987) said that cities are built the way they are financed. The financing of housing and of urban infrastructure and services is crucial to the functioning of cities.
