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.
For as long has humans have lived in communities, storytelling has bound people to each other and to their environments. In recent times, scholars have noted how social networks arise around issues of resource and ecological management.
Conventional wisdom about the environmental impact of cities holds that urbanization and environmental quality are necessarily at odds. Cities are seen to be sites of ecological disruption, consuming a disproportionate share of natural resources, producing high levels of pollution, and concentrating harmful emissions precisely where the population is most concentrated. Cities appear to be particularly vulnerable to natural disasters, to be inherently at risk from outbreaks of infectious diseases, and even to offer dysfunctional and unnatural settings for human life.
Boston’s metropolitan landscape has been two hundred years in the making. From its proto-suburban village centers of 1800 to its far-flung, automobile-centric exurbs of today, Boston has been a national pacesetter for suburbanization. In The Hub’s Metropolis, James O’Connell charts the evolution of Boston’s suburban development.
Today most major cities have undertaken some form of sustainability initiative. Yet there have been few systematic comparisons across cities, or theoretically grounded considerations of what works and what does not, and why. In Taking Sustainable CitiesSeriously, Kent Portney addresses this gap, offering a comprehensive overview and analysis of sustainability programs and policies in American cities.
Although nature conservation has traditionally focused on the countryside, issues of biodiversity protection also appear on the political agendas of many cities. One of the emblematic examples of this now worldwide trend has been the German city of Berlin, where, since the 1970s, urban planning has been complemented by a systematic policy of “biotope protection”—at first only in the walled city island of West Berlin, but subsequently across the whole of the reunified capital.
Urban freeways often cut through the heart of a city, destroying neighborhoods, displacing residents, and reconfiguring street maps. These massive infrastructure projects, costing billions of dollars in transportation funds, have been shaped for the last half century by the ideas of highway engineers, urban planners, landscape architects, and architects—with highway engineers playing the leading role.
Bicycling in cities is booming, for many reasons: health and environmental benefits, time and cost savings, more and better bike lanes and paths, innovative bike sharing programs, and the sheer fun of riding. City Cycling offers a guide to this urban cycling renaissance, with the goal of promoting cycling as sustainable urban transportation available to everyone.
Can a celebrity chef find common ground with an urban community organizer? Can a maker of organic cheese and a farm worker share an agenda for improving America’s food? In the San Francisco Bay area, unexpected alliances signal the widening concerns of diverse alternative food proponents. What began as niche preoccupations with parks, the environment, food aesthetics, and taste has become a broader and more integrated effort to achieve food democracy: agricultural sustainability, access for all to good food, fairness for workers and producers, and public health.
Over the past hundred years of urbanization and suburbanization, four key themes have shaped urban and regional planning in both theory and practice: livability, territoriality, governance, and reflective professional practice. Planning Ideas That Matter charts the trajectories of these powerful planning ideas in an increasingly interconnected world.
