Title: Urbanization


1
Urbanization
2
Urbanization and Urban Geography
  • Cities and towns pivotal to economic and social
    organization
  • Mobilizing function
  • Efficient environments for organizing labor,
    capital and raw materials
  • Decision making
  • Concentrations of political and economic power

3
Urbanization and Urban Geography
  • Generative functions
  • Facilitate innovation, knowledge creation,
    information
  • Transformative capacity
  • Escape from the rigidities of traditional, rural
    society

4
Urban Systems
  • Urban system
  • Interdependent set of urban settlements
  • Share some common attributes
  • Differ in other ways
  • Urban form
  • Physical structure and organization of cities in
    their land use, layout and built environment

5
Urban Systems
  • Urban ecology
  • Social and demographic composition of city
    districts and neighborhoods
  • Urbanism
  • How life in the city is lived
  • Ie., distinct (?) way of life fostered by urban
    settings
  • Often results in distinctive attitudes, values
    and patterns of behavior

Central Places
  • Cities and towns are organized in a number of
    overlapping ways
  • As a hierarchy of central places
  • Central place
  • A settlement with certain types of products and
    services
  • Smaller (lower order) places
  • provide only those goods to meet every day needs
  • Located relatively close to each other
  • Spread across the countryside

8
Central Places
  • Larger Settlements
  • Offer greater varieties of more specialized goods
    and services
  • Fewer in number
  • Located further away from each other
  • Range
  • The distance which people will travel to purchase
    a good
  • Threshold
  • The volume of purchases needed to sustain a
    business

9
Functional Differentiation
10
Rank Size Rule
  • The population of a given city tends to be equal
    to the population of the largest city divided by
    the rank of the given city
  • ie., Pr Pi/R
  • Where
  • Pr Population of the Rth city
  • Pi population of the largest city in the set
  • Rrank of the Rth city in the set

11
Primate Cities
  • Primate Cities
  • A city which is at least greater than twice the
    size of the next largest city in that country
  • E.g., Paris, Bangkok, Thailand
  • Often times the Primate city far more than simply
    greater than twice the size of the next largest
    city
  • E. g. London 7,074,265
  • Birmingham 1,020,589

12
Primate Cities
  • Primate cities and development ?
  • No direct correlation
  • In poorer countries Primacy may be a problem
  • Concentrates both growth and poverty into one
    place
  • Makes it more difficult of other areas of the
    country to grow

13
World Cities
  • Command and Control centers in the World Economy
  • Centers controlling the flows of information,
    cultural products and finances that organize the
    global economy
  • Leading global markets for commodities, commodity
    futures, investment capital, foreign exchange

14
World Cities
  • Specialized business services
  • i.e., Quaternary sector
  • Concentrations of corporate headquarters
  • Decision making
  • HQs of trade and professional organizations
  • HQs of NGOs
  • Media Centers
  • Sites of terrorist attacks

15
World Cities
  • Some are specialized
  • E.g., Milan (fashion) Brussels (EU)
  • Some diversified
  • New York
  • Some regionally specialized
  • Miami (Middle and South America)

16
Urbanization
  • 1/2 of the population of the world live in
    cities
  • Depends somewhat on how cities are defined
  • Canada 1,000city
  • Japan 50,000city
  • Large regional differences in urbanized
  • See next slide

17
Urbanization trends
18
Urbanization trends
  • Differences between Core countries and periphery
    and semi-periphery countries
  • 1950 (top 30)
  • 21 of largest cities in the Core
  • 11 in Europe 6 in the U.S.
  • 1980
  • 19 of largest were in Semi-periphery and
    semi-periphery
  • 2010
  • 25 in semi-periphery and periphery

19
Urbanization trends
  • In Core
  • Rates of urbanization slow
  • In periphery and semi-periphery
  • Urbanization rates very high Driven by
  • Demographic gap
  • Rural to urban migration
  • Continued high levels of internal growth
  • Little matching economic growth
  • e.g., Rio de Janeiro

20
Urbanization trends
  • Semi-periphery and periphery
  • 25-75 of the population
  • Instant slums
  • Squatter settlements
