Questions

- What is this state’s major industry?

- How dependent is the new state on its former colonizer (France)

- Does Kaclandia have natural resources. If so, where are they located?

- What is Kaclandia’s population? What are its demographics (especially its labor force)?

- Does the new state plan on building new religious structures?

Today

Unit 8 (Urban Geography)

Some basic terms

City: A conglomeration of people and buildings clustered together to serve as a center of politics, culture, and economics

Urban: The buildup of the city and surrounding environs connected to the city (central city and suburbs)

Urbanization: Movement of people from rural to urban areas—can happen very quickly in the modern world

Global Urban Population

Australia

Where are cities located and why?

Site• Absolute location• Static location, often

chosen for trade, defense, or religion

Situation• Relative location• A city’s place in the

region and the world around it

• Trade area: An adjacent region within which a city’s influence is dominant

Trade Areas

Rank-size rule• Characteristic of a model urban hierarchy • The population of the city or town is 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

Primate cityThe leading city of a country, disproportionately larger than the rest of the cities

Factors affecting primate cities:

- spread of colonialism

- strong centralized government

- economic factors

- rural-urban migration

- efficiency of modern transport

Advantages of primate cities

- Economies of large scale can be achieved because these cities attract overseas investment and benefits that can benefit the entire country/state.

- Attractive places of migration.

- Resources, services, and infrastructure available on a large scale.

Problems faced by primate cities

- housing shortages

- traffic congestion

- crime

- pollution

- increase in land value (unaffordable housing)

- imbalance in development

Primate cities - examples

- France: Paris (popn. 9.6 million)

Marseilles, France’s next largest city (popn. 1.3 million)

- U.K.: London (popn. 7 million)

Next largest city (Birmingham) popn. 1 million.

- South Korea: Seoul (popn. 10 million)

20% of the country’s population.

Countries without primate cities

- India: Most populous city = Mumbai (16 million)

second most populous: Kolkata (13 million)

- China, Canada, Australia, Brazil, U.S.

Central Place Theory (Christaller)

- Predicts how and where central places in the urban hierarchy (hamlets, villages, towns, and cities) are functionally and spatially distributed

- Assumes that–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

C = city

T = town

V = village

H = hamlet

Organization of Cities and how Cities Function

Urban morphology: The layout of a city, its physical form and structure

Functional zonation: The division of the city into certain regions (zones) for certain functions (purposes)

Zones of a city

Zones

- Central business district (CBD)

- Central City (the CBD + older housing zones)

- Suburb (outlying, functionally uniform zone outside of

the central city)

Modeling the North American city

- Concentric zone model (Ernest Burgess)

- Sector model (Homer Hoyt)

- Multiple-nuclei model (Chauncy Harris and Edward

Ullman)

Classical models of urban structure

Edge citiesSuburban downtowns, often located near key freeway intersections, including

- Office complexes- Shopping centers- Hotels- Restaurants - Entertainment facilities- Sports complexes

Urban Realms model

Each realm a separate economic, social, and political entity that is linked together to form a larger metropolitan framework

Satellite cities

Seoul Capital Area

Satellite cities

Example: Seoul Capital Area (Sudogwon)

- Central city is Seoul (“Seoul Special City”)

Satellite cities include:

- Incheon - Suwon - Ansan - Anyang - Goyang - Seongnam - Bucheon - Yongin

The Seoul Capital Area is the world’s second largest metropolitan area

popn. 25,000,000

Cities of periphery and semi-periphery

Latin America

Cities of periphery and semi-periphery• Griffin-Ford model

• Blend of Latin American traditions with globalization

• Disamenity sectors• Not connected to city services

• May be controlled by gangs and drug lords

• Industrial park• Gentrification area

Example: Rio De Janeiro (Brazil)

Industrial park

Cities of periphery and semi-periphery

Subsaharan Africa

De Blij model

- Low levels of urbanization but rapid growth rates

- European colonial imprint

Nairobi, Kenya

Accra, Ghana

Abidjan, Ivory Coast

Cape Town, South Africa

Satellite township: Cape Town

Cities of periphery and semi-periphery

McGee model

- Colonial port and surrounding commercial zone as focal point

Functional zonation – real-life example

Xiamen

How people make cities

Role of powerful social and cultural forces

Periphery and semi-periphery:

- Sharp contrast between rich and poor

- Often lack zoning laws or enforcement of

zoning laws

Making cities in the core (U.S.)

Redlining: Financial institutions refusing to lend money in certain neighborhoods

Blockbusting : Realtors purposefully selling a home at a low price to an African American and then soliciting white residents to sell their homes at low prices, to generate “white flight”

Making cities in the core (U.S.)

Gentrification: Individuals buying and rehabilitating houses, raising the housing value in the neighborhood

Gentrification (Harlem, New York)

Gentrification (Harlem, New York)

Making cities in the core (U.S.)Commercialization: City government transforminga central city to attract residents and tourists, often in stark contrast to the rest of the central city

Making cities in the core (U.S.)

Tear-downs: Houses that new owners buy with the intention of tearing them down to build much larger homes

McMansions: Large homes, often built to the outer limits of the lot

Making cities in the core (U.S.)

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

Making cities in the core (U.S.)

Urban Sprawl:

New Urbanism

Development, urban revitalization, and suburban reforms that create walkable neighborhoods with a diversity of housing and jobs

Concerns:

- Privatization of public spaces

- Failure to address conditions that create social ills of

cities

- Countering urban sprawl

New Urbanism

Next Class

- Wrap up Unit 8

- Introduce Unit 9 (Industries and Services)
