It's a mid-rise building that encompasses nearly an entire city block, usually developed over a surfacing parking lot or under-utilized former industrial site. There are countless more examples, even at the townhouse level (two examples from Minneapolis' downtown: here and here). Certainly, the loss of a parking lot is nothing to shed a tear over, but this building typology, which currently represents our American view of 'urban', presents itself as somewhat problematic.

In a piece called The Beauty of Urban Planning from Space, the Sustainable Cities Collective highlights views from space of uniquely designed street pattern designs in various cities around the world. There are ten examples that illustrate the zenith of urban planning. As attractive as the street patterns are, they highlight the inevitable inability of designers, or anyone else for that matter, to influence much more than small changes in the overall urban form.

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.

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.

n 2011, the World Bank initiated the Partnership for Sustainable Cities, a group of leading urban actors with a mission to collaborate on city development around the world and foster city-led sustainable development. This synthesis paper, Building Sustainability in an Urbanizing World, is a product of the partnership's early discussions. In this paper, members of the partnership have collaborated to identify and analyze the issues that guide their work together. The report summarizes the sustainability issues faced by cities and points toward the road ahead. It reviews successes in policy as well as investment and discusses what is needed to reach out to the rapidly growing cities of the developing world and make them effective users of existing knowledge. Examples of programs established by the partners are described in both the text and the Annexes. This report aims to be useful to the partners who contributed with knowledge and experiences, to cities who may benefit from an honest discussion of what works and what needs improvement, and to businesses and development practitioners entering the wide world of sustainable cities.
