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.

But the question remains: How exactly - in what ways and through which channels - does density make our cities more productive? That's where a recent study published in the Journal of Regional Science breaks new ground. Conducted by economists Jaison Abel of the Federal Reserve Bank of New York, Ishita Dey of the University of Georgia, and Todd Gabe of the University of Maine, the study provides new evidence of the relationships between density, human capital, and urban productivity. It uses detailed statistical models to gauge more precisely the effects of density and human capital, separately and together, on productivity of more than 350 metro areas.

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.

The City 2.0 website is a platform created to surface the myriad stories and collective actions being taken by citizens around the world. We draw on the best of what is already being discovered by urban advocates and add grassroots movers and shakers into the mix. What's emerging is a complex picture of the future city--a place more playful, more safe, more beautiful, and more healthy for everyone. http://www.ted.com/pages/tedx_tedxcity
