The semicircular shaped Grand Circus Park in Detroit, Michigan is divided by several streets, making it look like the hub and spokes of a bicycle wheel from above. The grouping of buildings along Grand Circus Park (Fig 9.1) reflects the
rise, fall, and revitalization of the central business district (CBD) in Detroit. The central business district is a concentration of business and commerce in the citys downtownAbandoned high-rise buildings called the ghosts of Detroit are joined by empty single-family homes to account for 10,000 abandoned buildings in the city. 2012 John Wiley & Sons, Inc.

When and Why Did People Start Living in Cities? Greek Cities Greece is described as a secondary hearth of urbanization because the Greek city form and function diffused around the world centuries later
through European colonialism. Every city had its acropolis, on which the people built the most impressive structures. Agora (market) became the focus of commercial activity. Urbanization diffused from Greece to the Roman Empire. 2012 John Wiley & Sons, Inc. All rights reserved. 2012 John Wiley & Sons, Inc. All rights reserved. Roman Cities When the Romans succeeded the Greeks (and Etruscans) as rulers of the region, their empire
incorporated not only the Mediterranean shores but also a large part of interior Europe and North Africa. The site of a city is its absolute location, often chosen for its advantages in trade or defense, or as a center for religious practice. The situation of a city is based on its role in the larger, surrounding context: A citys situation changes with times. Ex.: Rome becoming the center of the Roman Catholic Church. 2012 John Wiley & Sons, Inc. All rights reserved. 2012 John Wiley & Sons, Inc. All rights reserved.
When and Why Did People Start Living in Cities? Roman Cities Urban morphology: a citys layout; its physical form and structure. Whenever possible, Romans adopted the way the Greeks planned their colonial cities; in a rectangular, grid pattern. Functional zonation reveals how different areas or segments of a city serve different purposes or functions within the city. Ex.: the Forum 2012 John Wiley & Sons, Inc. All rights reserved.
Field Note There can be few spaces of greater significance to the development of Western civilization than the Roman Forum. This was the nerve center of a vast empire that transformed the face of western Europe, Southwest Asia, and North Africa. It was also the place where the decisions were made that carried forward Greek ideas about governance, art, urban design, and technology. The very organization of space found in the
Roman Forum is still with us: rectilinear street patterns; distinct buildings for legislative, executive, and judicial functions; and public spaces adorned with statues and fountains. 2012 John Wiley & Sons, Inc. All rights reserved. Urban Growth After Greece and Rome During Europes Middle Ages, urbanization continued vigorously outside of Europe. In West Africa, trading cities developed along the
southern margin of the Sahara. The Americas also experienced significant urban growth, especially within Mayan and Aztec empires. 2012 John Wiley & Sons, Inc. All rights reserved. Site and Situation during European Exploration The relative importance of the interior trade
routes changed when European maritime exploration and overseas colonization ushered in an era of oceanic, worldwide trade. The situation of cities like Paris and Xian changed from being crucial in an interior trading route to being left out of an oceanic trade. After European exploration took off during the 1400s, the dominance of interior cities declined. 2012 John Wiley & Sons, Inc. All rights reserved. Site and Situation during European Exploration Coastal cities remained crucial after exploration
led to colonialism The trade networks European powers commanded (including the slave trade) brought unprecedented riches to Europes burgeoning medieval cities, such as Amsterdam (the Netherlands), London (England), Lisbon (Portugal), Liverpool (England), and Seville (Spain) As a result, cities that thrived during mercantilism took on similar properties 2012 John Wiley & Sons, Inc. All rights reserved. Field Note The contemporary landscape of Genoa stands as a reminder of the citys historic
importance. Long before Europe became divided up into states, a number of cities in northern Italy freed themselves from the strictures of feudalism and began to function autonomously. Genoa and Venice were two of these, and they became the foci of significant Mediterranean maritime trading empires. In the process, they also became magnificent, wealthy cities. Although most buildings in Genoas urban core date from a more recent era, the layout of streets and public squares harkens back to the citys imperial days. Is it a surprise that the city gave birth to one of the most famous explorers of all time: Christopher Columbus? 2012 John Wiley & Sons, Inc. All rights reserved. When and Why Did People Start Living in Cities? A Second Urban
Revolution Around 1800, Western Europe was still overwhelmingly rural. As thousands migrated to the cities with industrialization, cities had to adapt to the mushrooming population, the proliferation of factories and supply facilities, the expansion of transport systems, and the construction of tenements for the growing labor force. 2012 John Wiley & Sons, Inc. All rights reserved. When and Why Did People Start Living in Cities?
A Second Agricultural Revolution During the late seventeenth century and into the eighteenth century, Europeans invented a series of important improvements in agriculture. The second agricultural revolution also improved organization of production, market collaboration, and storage capacities. Many industrial cities grew from small villages or along canal and river routes. 2012 John Wiley & Sons, Inc. All rights reserved. When and Why Did People
Start Living in Cities? When industrialization diffused from Great Britain to the European mainland, the places most ready for industrialization had undergone their own second agricultural revolution, had surplus capital from mercantilism and colonialism, and were located near coal
fields. 2012 John Wiley & Sons, Inc. All rights reserved. When and Why Did People Start Living in Cities? The Chaotic Industrial City With industrialization, cities became unregulated jumbles of activity. Living conditions were dreadful for workers in cities, and working conditions were shocking.

The Chaotic Industrial City In mid-1800s, as Karl Marx and Frederick Engels encouraged workers of the world to unite, conditions in European manufacturing cities gradually improved. During the second half of the twentieth century, the nature of manufacturing changed, as did its
location. Concept Caching: Duisburg, Germany 2012 John Wiley & Sons, Inc. All rights reserved. Archaeologists have found that the houses in Indus River cities, such as Mohenjo-Daro and Harappa, were a uniform size: each house had access to a sewer system, and palaces were absent from the cultural landscape.

had both a leadership class and a surplus of agricultural goods. 2012 John Wiley & Sons, Inc. All rights reserved. Key Question Where are cities located, and why? 2012 John Wiley & Sons, Inc. All rights reserved. Where Are Cities Located, and Why? Urban geographers discovered that every
city and town has a trade area, an adjacent region within which its influence is dominant.

Rank and Size in the Urban Matrix The rank-size rule holds that in a model urban hierarchy, the population of a city or town will be inversely proportional to its rank in the hierarchy. German Felix Auerbach, linguist George Zipf. Random growth (chance) and economies of scale (efficiency) explain why the rank-size rule works where it does. The rank-size rule does not apply in all countries, especially countries with one dominant city. Mark Jefferson: A primate city is a countrys leading city, always disproportionately large and exceptionally expressive of national capacity and feeling.
2012 John Wiley & Sons, Inc. All rights reserved. Central Place Theory Central place theory: Walter Christaller, The Central Places in Southern Germany (1933), had five assumptions: 1. The surface of the ideal region would be flat and have no physical barriers. 2. Soil fertility would be the same everywhere 3. Population and purchasing power would be evenly distributed. 4. The region would have a uniform transportation network to permit direct travel from each settlement to the other.
5. From any given place, a good or service could be sold in all directions out to a certain distance. 2012 John Wiley & Sons, Inc. All rights reserved. Central Place Theory Each central place has a surrounding complementary region, an exclusive trade area within which the town has a monopoly on the sale of certain goods.

United States are named, and their names typically coincide with the vernacular region, the region people perceive themselves as living in. In promoting a trade area, companies often adopt, name, or shape the name of the vernacular region. In Oklahoma, the label Green Country refers to the northeastern quarter of the state, the trade area served by Tulsa.

How Are Cities Organized, and How Do They Function? Models of the City Functional zonation: the division of the city into certain regions (zones) for certain
purposes (functions). Globalization has created common cultural landscapes in the financial districts of many world cities. Regional models of cities help us understand the processes that forged cities in the first place and understand the impact of modern linkages and influences now changing cities. 2012 John Wiley & Sons, Inc. All rights reserved. Functional Zones Zone is typically preceded by a descriptor that conveys the purpose of that area of the city.
Most models define the key economic zone of the city as the central business district (CBD). Central city describes the urban area that is not suburban. In effect, central city refers to the older city as opposed to the newer suburbs. A suburb is an outlying, functionally uniform part of an urban area, and is often (but not always) adjacent to the central city. Suburbanization is the process by which lands that were previously outside of the urban environment become urbanized, as people and businesses from the city move to these spaces. 2012 John Wiley & Sons, Inc. All rights reserved.
Functional Zones P.O. Muller: Contemporary Suburban America (1981): Found suburban cities ready to compete with the central city for leading urban economic activities. In addition to expanding residential zones, the process of suburbanization rapidly creates distinct urban regions complete with industrial, commercial, and educational components. 2012 John Wiley & Sons, Inc. All rights reserved. Modeling the North American City
Concentric zone model: resulted from sociologist Ernest Burgesss study of Chicago in the 1920s. Burgesss model divides the city into five concentric zones, defined by their function: 1. CBD is itself subdivided into several subdistricts. 2. Zone of transition is characterized by residential deterioration and encroachment by business and light manufacturing. 3. Zone 3 is a ring of closely spaced but adequate homes occupied by the blue-collar labor force. 4. Zone 4 consists of middle-class residences. 5. Zone 5 is the suburban ring. 2012 John Wiley & Sons, Inc. All rights reserved.
Modeling the North American City Homer Hoyt: Sector model The city grows outward from the center, so a low-rent area could extend all the way from the CBD to the citys outer edge, creating zones that are shaped like a piece of pie. The pie-shaped pieces describe the highrent residential, intermediate rent residential, low-rent residential, education and recreation, transportation, and industrial sectors. 2012 John Wiley & Sons, Inc. All rights reserved.
Modeling the North American City Chauncy Harris and Edward Ullman: multiple nuclei model This model recognizes that the CBD was losing its dominant position as the single nucleus of the urban area. Edge cities: Suburban downtowns developed mainly around big regional shopping centers; they attracted industrial parks, office complexes, hotels, restaurants, enter-tainment facilities, and sports stadiums. 2012 John Wiley & Sons, Inc.

During colonialism, Europeans laid out prominent urban centers. The centers of South Africas major cities (Johannesburg, Cape Town, and Durban) remain essentially Western. Studies of African cities indicate that the central city often consists of not one but three CBDs: a remnant of the colonial CBD, an informal and sometimes periodic market zone, and a transitional business center where commerce is conducted. 2012 John Wiley & Sons, Inc.

Field Note Central Cairo is full of the multistory
buildings, transportation arteries, and commercial signs that characterize most contemporary big cities. Outside of a number of mosques, few remnants of the old medieval city remain. The first blow came in the nineteenth century, when a French educated ruler was determined to recast Cairo as a world-class city. Inspired by the planning ideas of Pariss Baron von Hausman, he transformed the urban core into a zone of broad, straight streets. In more recent years the forces of modern international capitalism have had the upper hand. There is little sense
of an overall vision for central Cairo. Instead, it seems to be a hodge-podge of buildings and streets devoted to commerce, administration, and a variety of producer and consumer services. 2012 John Wiley & Sons, Inc. All rights reserved. Field Note Moving out from central Cairo, evidence of the citys rapid growth is all around you. These hastily built housing units are part of the (often losing) effort to keep up with the citys exploding growth. From a
city of just one million people in 1930, Cairos population expanded to six million by 1986. And then high growth rates really kicked in. Although no one knows the exact size of the contemporary city, most estimates suggest that Cairos population has doubled in the last 20 years. This growth has placed a tremendous strain on city services. Housing has been a particularly critical problemleading to a landscape outside the urban core dominated by hastily built, minimally functional, and aesthetically non-descript housing projects.

Shaping Cities in the Global Periphery and Semiperiphery Particularly in the economic periphery, new arrivals (and long-term residents) crowd together in overpopulated apartments, dismal tenements, and teeming slums. Cities in poorer parts of the world generally lack enforceable zoning laws. Across the global periphery, the one trait all major cities display is the stark contrast between
the wealthy and poor. 2012 John Wiley & Sons, Inc. All rights reserved. How Do People Share Cities?

2012 John Wiley & Sons, Inc. All rights reserved. How Do People Share Cities? In order to counter the suburbanization trend, city governments are encouraging commercialization of the central business district and gentrification of neighborhoods in and around the central business district. Commercialization entails transforming the central business district into an area attractive to residents and tourists alike. Gentrification is the rehabilitation of houses in older neighborhoods. Teardowns: suburban homes meant for
demolition; the intention is to replace them with McMansions. 2012 John Wiley & Sons, Inc. All rights reserved. Field Note In 2008, downtown Fort Worth, Texas looked quite different than it did when I first visited in 1997. In that eleven year period, business leaders in the City of Fort Worth gentrified the downtown. The Bass family, who has a great deal of wealth from oil holdings and who now owns about 40 blocks of downtown Fort Worth, was instrumental in the citys gentrification. In the 1970s and 1980s, members of the Bass
family looked at the empty, stark, downtown Fort Worth, and sought a way to revitalize the downtown. They worked with the Tandy family to build and revitalize the spaces of the city, which took off in the late 1990s and into the present century. The crown jewel in the gentrified Fort Worth is the beautiful cultural center called the Bass Performance Hall, named for Nancy Lee and Perry R. Bass, which opened in 1998.

Urban Sprawl and New Urbanism To counter urban sprawl, a group of architects, urban planners, and developer outlined an urban design vision they call new urbanism: development, urban revitalization, and suburban reforms that create walkable neighborhoods with a diversity of housing and jobs Geographer David Harvey argues the new urbanism movement is a kind of spatial determinism that does not recognize that the fundamental difficulty with modernism was its persistent habit of privileging spatial forms over
social processes. Other critics say communities that new urbanists form through their projects are exclusionary and 2012 John Wiley & Sons, Inc. All rights of reserved. deepen the racial segregation cities. Field Note When I visited
Celebration, Florida, in 1997, I felt like I was walking onto a movie or television set. The architecture in the Walt Disney designed new urbanist development looked like the quintessential New England town. Each house has a porch, but on the day I was there, the porches sat emptywaiting to welcome the arrival of their owners at the end of
the work day. We walked through town, past the 50s-style movie marquee, and ate lunch at a 50sstyle diner. At that point, Celebration was still growing.

How Do People Share Cities? Gated Communities Fenced-in neighborhoods with controlled access gates for people and automobiles. Main objective is to create a space of safety within the uncertain urban world. Secondary objective is to maintain or increase housing values in the neighborhood through enforcement of the neighborhood associations bylaws.

How Do People Share Cities? Ethnic Neighborhoods in the European City Ethnic neighborhoods in European cities are typically affiliated with migrants from former colonies. Migration to Europe is constrained by government policies and laws. European cities are typically more compact, densely populated, and walkable than American cities. Housing in the European city is often combined with places of work. 2012 John Wiley & Sons, Inc. All rights reserved.
How Do People Share Cities? Government Policy and Immigrant Accommodation Whether a public housing zone is divided into ethnic neighborhoods in a European city depends in large part on government policy.

Ethnic Neighborhoods in the Global Periphery and Semiperiphery City In cities of the periphery and semiperiphery, a sea of slum development typically begins where the permanent buildings end, in some cases engulfing and dwarfing the central city. Millions of migrants travel to such environments every year. City governments do not have the resources to adequately educate, medicate, or police the burgeoning populations. The vast slums of cities in poorer parts of the
world are typically ethnically delineated, with new arrivals precariously accommodated. 2012 John Wiley & Sons, Inc. All rights reserved. How Do People Share Cities?

Felsenstein, Schamp, and Shachar: The world city is a node in globalization, reflecting processes that have redrawn the limits on spatial interaction. World cities do not exist merely to service players in the global economy. Some countries such as the United States and Germany have two or more world cities within their state borders.
