The United States has evolved into a nation of twenty densely populated megaregions. Yet despite the environmental advantages of urban density, urban sprawl and reliance on the private car still set the pattern for most new development. Cars guzzle not only gas but also space, as massive acreage is dedicated to roadways and parking. Even more pressing, the replication of this pattern throughout the fast-developing world makes it doubtful that we will achieve the reductions in carbon emissions needed to avoid climate catastrophe.
In The New Science of Cities, Michael Batty suggests that to understand cities we must view them not simply as places in space but as systems of networks and flows. To understand space, he argues, we must understand flows, and to understand flows, we must understand networks—the relations between objects that comprise the system of the city.
Buildings are the nation’s greatest energy consumers. Forty percent of all our energy is used for heating, cooling, lighting, and powering machines and devices in buildings. And despite decades of investment in green construction technologies, residential and commercial buildings remain stubbornly energy inefficient.
Urbanization and globalization have shaped the last hundred years. These two dominant trends are mutually reinforcing: globalization links countries through the networked communications of urban hubs. The urban population now generates more than eighty percent of global GDP. Cities account for enormous flows of energy and materials—inflows of goods and services and outflows of waste. Thus urban environmental management critically affects global sustainability.
In mid-twentieth century France, the term “social space” (l’espace social)—the idea that spatial form and social life are inextricably linked—emerged in a variety of social science disciplines. Taken up by the French New Left, it also came to inform the practice of urban planning. In The View from Above, Jeanne Haffner traces the evolution of the science of social space from the interwar period to the 1970s, illuminating in particular the role of aerial photography in this new way of conceptualizing socio-spatial relations.
The maps in this book are drawn with satellites, assembled with pixels radioed from outer space, and constructed from statistics; they record situations of intense conflict and express fundamental transformations in our ways of seeing and of experiencing space. These maps are built with Global Positioning Systems (GPS), remote sensing satellites, or Geographic Information Systems (GIS): digital spatial hardware and software designed for such military and governmental uses as reconnaissance, secrecy, monitoring, ballistics, the census, and national security.
“Where does the city without gates begin? Perhaps inside that fugitive anxiety, that shudder that seizes the minds of those who, just returning from a long vacation, contemplate the imminent encounter with mounds of unwanted mail or with a house that’s been broken into and emptied of its contents. It begins with the urge to flee and escape for a second from an oppressive technological environment, to regain one’s senses and one’s sense of self.”

There are an estimated 600,000,000 passenger cars in the world, and that number is increasing every day. So too is Earth’s supply of parking spaces. In some cities, parking lots cover more than one-third of the metropolitan footprint. It’s official: we have paved paradise and put up a parking lot. In ReThinking a Lot, Eran Ben-Joseph shares a different vision for parking’s future. Parking lots, he writes, are ripe for transformation. After all, their design and function has not been rethought since the 1950s.
By the end of the twentieth century, America’s suburbs contained more office space than its central cities. Many of these corporate workplaces were surrounded, somewhat incongruously, by verdant vistas of broad lawns and leafy trees. In Pastoral Capitalism, Louise Mozingo describes the evolution of these central (but often ignored) features of postwar urbanism in the context of the modern capitalist enterprise.
Cities speak, and this little book helps us understand their language. Considering the urban landscape not from the abstract perspective of an urban planner but from the viewpoint of an attentive observer, Urban Code offers 100 "lessons”--maxims, observations, and bite-size truths, followed by short essays--that teach us how to read the city. This is a user’s guide to the city, a primer of urban literacy, at the pedestrian level.
