1. Urban Geography
Chapter 9

2. When and Why did People Start Living in Cities?
Key Question:
When and Why did People Start Living in Cities?

3. Cities
City – a conglomeration of people and buildings clustered together to serve as a center of politics, culture, and economics.

4. Urban:
The buildup of the central city and the suburban realm – the city and the surrounding environs connected to the city.

5. Shenzhen, China The Modern Process of Urbanization –
a rural area can become urbanized quite quickly in the modern world

6. Shenzhen, China
Shenzhen changed from a fishing village to a major metropolitan area in just 25 years. 25 years ago, all of this land was duck ponds and rice paddies.

7. The First Urban Revolution

8. Agricultural Villages
Before urbanization, people often clustered in agricultural villages –
a relatively small, egalitarian village, where most of the population was involved in agriculture. About 10,000 years ago, people began living in agricultural villages

9. The First Urban Revolution
Two components enable the
formation of cities:
1. an agricultural surplus
2. social stratification
(a leadership class)

10. Five Hearths of Urbanization
In each of these hearths, an agricultural surplus and social stratification created the conditions necessary for cities to form and be maintained.

11. Five Hearths of Urbanization
Mesopotamia, 3500 BCE
Nile River Valley, 3200 BCE
Indus River Valley, 2200 BCE
Huang He and Wei River Valleys, 1500 BCE
Mesoamerica, 200 BCE

12. Indus River Valley
Harappa and Mohenjo-Daro were two of the first cities of the Indus River Valley.
- intricately planned
- houses equal in size
- no palaces
- no monuments

13. Huang He and Wei River Valleys
The Chinese purposefully planned their cities.
- centered on a
vertical structure
- inner wall built
around center
- temples and
palaces for the
leadership class

14. Mesoamerica Mayan and Aztec Civilizations
Many ancient cities were theocratic centers where rulers were deemed to have divine authority and were god-kings.

15. Mesoamerica
Between 300 and 900 CE, Altun Ha, Belize served as a thriving trade and distribution center for the Caribbean merchant canoe traffic.

16. Diffusion of Urbanization
The Greek Cities
by 500 BCE, Greeks were highly urbanized.
Network of more than 500 cities and towns
On the mainland and on islands
Each city had an acropolis and an agora

17. Athens, Greece
the agora
the acropolis

18. Diffusion of Urbanization
The Roman Cities
a system of cities and small towns, linked together with hundreds of miles of roads and sea routes.
Sites of Roman cities were typically for trade
A Roman city’s Forum combined the acropolis and agora into one space.
Roman cities had extreme wealth and extreme poverty (between 1/3 and 2/3s of empire’s population was enslaved)

19. Roman Empire

20. The Roman Forum
Aqueducts in Nimes, France

21. During the mercantile era, the cities that thrived were embellished by wealthy merchant families, who built ornate mansions, patronized the arts, participated in city governments, and supported the reconstruction of city centers.
Genoa, Italy

22. The Second Urban Revolution

23. The Second Urban Revolution
A large scale movement of people to cities to work in manufacturing. Made possible by:
1. second agricultural revolution that improved food production and created a larger surplus
2. industrialization, which encouraged growth of cities near industrial resources

24. Industrialized regions of Europe, 1914

25. During the second half of the 20th century…
Nature of manufacturing changed and locations changed, too. Many factories have been abandoned, creating “rust belts” out of once-thriving industrial districts.
Duisburg, Germany

26. 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. Derive a theory as to why these conditions were present in these cities that had both a leadership class and a surplus of agricultural goods.

27. Where are Cities Located and Why?
Key Question:
Where are Cities Located and Why?

28. Site and Situation Site Situation * absolute location of a city
* a city’s static location, often chosen for trade, defense, or religion.
Situation
* relative location of a city
* a city’s place in the region and the world around it.

29. Trade area
Trade area – an adjacent region within which a city’s influence is dominant.
Green Country, Oklahoma

30. Rank-Size Rule:
in a model urban hierarchy, the population of the city or town will be inversely proportional to its rank in the hierarchy.
For example:
largest city = 12 million
2nd largest = 6 million
3rd largest = 4 million
4th largest = 3 million

31. Primate City
The leading city of a country. The city is disproportionately larger than the rest of the cities in the country.
For example: London, UK
Mexico City, Mexico
Paris, France
- the rank-size rule does not work for a
country with a primate city

32. Central Place Theory
Walter Christaller developed a model to predict how and where central places in the urban hierarchy (hamlets, villages, towns, and cities) would be functionally and spatially distributed.
Assumed: surface is flat with no physical barriers
soil fertility is the same everywhere
population and purchasing power are evenly distributed
region has uniform transportation network
from any given place, a good or service could be sold in all directions out to a certain distance

33. Hexagonal Hinterlands
C = city
T = town
V = village
H = hamlet

34. Sketch a map of your city or town and the cities or towns nearby
Sketch a map of your city or town and the cities or towns nearby. Make a list of goods and services available in each of these towns. Do the ideas about central places presented in this section of the chapter apply to your region?

35. How are Cities Organized, and How do they Function?
Key Question:
How are Cities Organized, and How do they Function?

36. Urban Morphology The layout of a city, its physical form an structure.
Berlin, Germany
With wall (above)
And without wall (right)
What does the urban morphology of the city tell us about the city?

37. Functional Zonation
The division of the city into certain regions (zones) for certain purposes (functions).
Cairo, Egypt
Central city (above)
Housing projects (right)
What does the functional zonation of the city tell us about the city?

38. Zones of the City Central business district (CBD)
Central City (the CBD + older housing zones)
Suburb (outlying, functionally uniform zone outside of the central city)

39. Modeling the North American City
Concentric zone model (Ernest Burgess)
Sector model (Homer Hoyt)
Multiple Nuclei Model
(Chauncy Harris and Edward Ullman)

40. Three Classical Models of Urban Structure

41. Edge Cities
Suburban downtowns, often located near key freeway intersections, often with:
- office complexes
- shopping centers
- hotels
- restaurants
- entertainment facilities
- sports complexes

42. Urban Realms Model
Each realm is a separate economic, social and political entity that is linked together to form a larger metro framework.

43. Modeling the Cities of the Global Periphery and Semiperiphery
Latin American City (Griffin-Ford model)
African City (de Blij model)
Southeast Asian City (McGee model)

44. Latin American City (Griffin-Ford model)

45. Disamenity sector – very poorest parts of the city eg
Disamenity sector – very poorest parts of the city eg. the favelas of Rio de Janeiro, Brazil

46. The African City (de Blij model)

47. Southeast Asian City (McGee model)

48. Employing the concepts defined in this section of the chapter, draw a model of the city with which you are most familiar. Label each section of the city accordingly. After reading through the models described in this section, determine which model best corresponds to the model you drew and hypothesize why it is so.

49. How do People Make Cities?
Key Question:
How do People Make Cities?

50. Powerful social and cultural forces shape the character of a city and create the cultural landscape of the city.

51. Making Cities in the Global Periphery and Semiperiphery
sharp contrast between rich and poor
- Often lack zoning laws or enforcement of zoning laws

52. Making Cities in the Global Core
Redlining – financial institutions refusing to lend money in certain neighborhoods.
Blockbusting – realtors purposefully sell a home at a low price to an African American and then solicit white residents to sell their homes and low prices, to generate “white flight.”

53. Making Cities in the Global Core
Gentrification – individuals buy up and rehabilitate houses, raising the housing value in the neighborhood and changing the neighborhood.
Commercialization – city governments transform a central city to attract residents and tourists. The newly commercialized downtowns often are a stark contrast to the rest of the central city.

54. Tear-downs – houses that new owners buy with the intention of tearing it down to build a much larger home. McMansions – large homes, often built to the outer limits of the lot. They are called McMansions because of their super size and their similar look.
Hinsdale, Illinois (25% of houses have been torn down in last 20 years).

55. Urban Sprawl
Unrestricted growth of housing, commercial developments, and roads over large expanses of land, with little concern for urban planning.
Henderson, Nevada

57. New Urbanism
Development, urban revitalization, and suburban reforms that create walkable neighborhoods with a diversity of housing and jobs.
some are concerned over privatization of public spaces
some are concerned that they do nothing to bread down the social conditions that create social ills of the cities
some believe they work against urban sprawl

58. Celebration, Florida

59. Celebration, Florida

60. Who are gated communities for?
How do the goals/purposes of gated communities differ across the world?

61. Ethnic Neighborhoods European City
eg. Muslim neighborhoods in Paris
Cities of the Periphery and Semiperiphery
eg. Mumbai, India

62. Mumbai, India

63. Using the city you sketched in the last “Thinking Geographically” question, consider the concepts and processes introduced in this section of the chapter and explain how people and institutions created this city and the model you sketched.

64. What Role do Cities Play in Globalization?
Key Question:
What Role do Cities Play in Globalization?

65. World Cities
Cities that function at the global scale, beyond the reach of the state borders, functioning as the service centers of the world economy.

66. Spaces of Consumption
The transformation of the city into an entertainment district, where major corporations encourage the consumption of their goods and services.
For example: Berlin, Germany
New York City

67. Times Square New York City

68. Thinking through the challenges to the state presented in Chapter 8, predict whether and under what circumstances world cities could replace states as the basic and most powerful form of political organization in the world.
