Macro forces continue to have an impact on the global influence of cities. Political power is rotating back from West to East, and with economic drivers having shifted from agrarian to industrial to information-based, more people live in cities than in rural areas. While New York, London, Paris, and Tokyo still rank among today's top cities, it appears that Beijing and Shanghai may become significant rivals in the next 10 to 20 years. These are among the highlights of the 2012 Global Cities Index (GCI), a joint study performed by A.T. Kearney and The Chicago Council on Global Affairs. In addition, a panel of academic and corporate executive advisors informed and challenged the study results. We've expanded this year's study; in addition to classifying the current global influence of 66 cities, we have also developed an Emerging Cities Outlook (ECO) to project which emerging-market cities may eventually rival the established global leaders for dominance. Figure 1 summarizes the 2012 results, along with the rankings from our 2008 and 2010 findings of major world metropolitan areas. (The censorship metric added in 2010 affected the positions of several emerging-market cities.) In the first section of this report, we explore the results and implications of the 2012 GCI rankings. The second section summarizes the results of our Emerging Cities Outlook, which analyzes the strengths and weaknesses of cities in developing markets by examining the rates of change and key factors that will affect their ability to capitalize on future globalization trends (see Appendix: About the Study).

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.

Hot spots is an Economist Intelligence Unit research programme, commissioned by Citigroup, which ranks the competitiveness of 120 of the world's major cities. The Economist Intelligence Unit bears sole responsibility for the content of this report. The Economist Intelligence Unit's editorial team built the Index, conducted the analysis and wrote the report. The findings and views expressed in this report do not necessarily reflect the views of the sponsor. Our research drew on two main initiatives: A unique Index that compares 120 of the world's major urban agglomerations across eight distinct categories of competitiveness and 31 individual indicators. These cities collectively represent about 29% of the global economy, with a combined GDP of US$20.24tr. A detailed note on definitions and methodology is provided in the appendix. We conducted in-depth interviews with ten city experts, mayors and corporate executives, to get their insights on city competitiveness.

The Global City Indicators Facility provides an established set of city indicators with a globally standardized methodology that allows for global comparability of city performance and knowledge sharing. This website serves all cities that become members to measure and report on a core set of indicators through this web-based relational database.

Urbanization usually leads to higher GDP because of higher levels of productivity, the report says, which is illustrated in the graph to the left. All five of the East Asia and Pacific countries in the graph show a steady increase in GDP per capita as people move to cities. But that did not happen for Sub-Saharan Africa; the graph on the right shows a sporadic relationship between urbanization and GDP.

In his just-released Planet of Cities, Shlomo Angel argues that urban policy-makers and planners must do more to meet the challenge of urbanization. Angel, who is a member of the Urbanization Project at New York University and who conducted his research as a visiting fellow at the Lincoln Institute of Land Policy, provides a detailed, data-driven analysis filled with maps of world urbanization patterns, as well as charts and tables documenting the challenges facing global cities. He took time out from his busy schedule to talk to Atlantic Cities about the key challenges facing our increasingly urban world.

Spain may be facing significant economic and political challenges these days, but Barcelona's city-building remains one of the best models in the world. Few cities inspire my thinking more. Thus it was a fitting location for the second Global Smart City Expo/Congress, and my invitation to speak was a good excuse to return, and share some of the best "steal-able" lessons. The Congress may have talked a lot about urban technologies, but Barcelona reminds us how smart the fundamentals are when it comes to making great cities.

LSE Cities is an international centre at the London School of Economics and Political Science that carries out research, education and outreach activities in London and abroad. Its mission is to study how people and cities interact in a rapidly urbanising world, focussing on how the design of cities impacts on society, culture and the environment. Through research, conferences, teaching and projects, the centre aims to shape new thinking and practice on how to make cities fairer and more sustainable for the next generation of urban dwellers, who will make up some 70 per cent of the global population by 2050.

Last year, I spent considerable time researching best practices for climate resilient cities--an endeavor that culminated in what I believe was the first ever global ranking of resilient cities. Now, after extensive research on smart cities initiatives around the globe, I have developed what may be the first ever global rankings of smart cities.

The report "Innovation and the City" [PDF] is an important addition to our knowledge of urban policy innovation. It summarizes the results of a six-month research effort by policy researchers at New York University's Wagner School of Public Service and the New York-based Center for an Urban Future. The research team interviewed over 200 experts (including our own Emily Badger) and surveyed more than 120 policy innovations. (I should disclose here that I am Global Research Professor for the NYU School of Continuing and Professional Studies).

The complexity of participation: learning from slum dweller mobilisation in Dar es Salaam Putting the practice of resident participation in displacement planning under the microscope, Michael Hooper provides six practical lessons for implementing a participation programme that recognises the differences between residents and makes all their voices count, based on research in Dar es Salaam.

On population growth and family planning: Bill Ryerson: Well, you brought up Population Media Center. One of the things that we do - and that is the primary thing we do - is to use a strategy of communications that has turned out, from everything we have been able to measure, to be the most cost-effective strategy for changing behavior with regard to family size and contraceptive use on a per-behavior change basis of any strategy we have found on the planet. And this is the use of long-running serialized dramas, melodramas like soap operas, in which characters gradually evolve from the middle of the road in that society into positive role models for daughter education, delaying marriage and childbearing until adulthood, spacing of children, limiting of family size, and various other health and social goals of each country. And we have now done such programs in forty-five countries. And I can give you a couple of statistics. For example, in northern Nigeria, a program we ran from 2007 to 2009 was listened to by 70% of the population at least weekly. It was a twice a week program. It was clearly a smash hit. And it was a smash hit because it was highly suspenseful and highly entertaining. But it had a storyline dealing with a couple deciding to use family planning, which is almost taboo in northern Nigeria because less than 10% of the people in that region use any modern method of contraception. We had eleven clinics have healthcare workers ask clients what had motivated them to come in for family planning, and 67% percent of them named the program as the motivation.
