    Urban

    Defined as places of intense social interaction and exchange between strangers

    Generally have a dense agglomeration(concentration) of people and activities

    Key characteristics are density, proximity and diversity

    Urbanization

    Population shifting towards the urban areas

    De-urbanization is the opposite (rural areas have a population growth)

    Metropolitanization

    Metropolitan(larger urban areas) growing faster than the smaller urban areas

    Suburbanization

    Suburban area population increase

    Principle Methods used to measure urban places:

    1) Population

    2) Economic Base

    3) Administrative

    4) Functional

    Note: Basic goods = City forming (agriculture, manufacturing)

    Non-Basic goods = city serving (government services)

    Urban Geography

    Is about,

    Understanding the distribution of towns and cities

    Accounting for the similarities and differences between them

    Main themes :

    o System of citiesdistribution of cities & towns

    o City as a systeminternal structure of a system

    In Urban Geography we,

    Recognize and describe the following of the urban area

    o Pattern, processes

    o Internal structure

    Examine how people understand/react to these observed patterns/processes

    Seek for how these patterns/processes originated

    Approaches to Urban Geography:

    EnvironmentalismRelationship between people and their environment

    o Site and situational studies

    o Urban morphology

    o Focuses on production, form and design of urban areas

    PositivismHuman behavior is influenced by scientific/universal laws and therefore this

    produces observable patterns of urban activity

    o 2 main approaches

    EcologicalHuman behavior is based on ecological principles.

    The most powerful groups get the most advantageous place in a given

    space

    Example : Burgess Concentric Zone Model

    The idea behind this model is that the city grows outward from a central area in a

    series of rings. The size of the rings may vary, but the order always remains the same.

    This model suggests that the social structure extends outwards from the central

    business district, meaning that the lower classes live closer to the city center, while

    the upper classes live farther from the city center because they can afford the

    commute. Also, as you get further away from the city density decreases. The rent

    tends to increase as you get further away from the CBD and residents are more likely

    to rent near the center. As you get further away from the CBD it is more likely that

    you will find condominiums. However, this model has its weaknesses. It does not take

    into account any physical barriers and it does not take into account gentrification-

    which may occur in these cities.

    Neo-ClassicalDriving force is rationality (or rather, the economic rationality of

    humans). Cost-minimization or benefits maximization.

    Behavioral and Humanistic

    o The difference

    BehavioralFocused on decision making, on human behaviour, but seeks

    generalizations(for a model-like way)

    HumanisticDeeply subjective and complex relations exist between individuals

    and groups

    StructuralismImportance of social, economic and political structures in society.

    o Derived from the work of Karl Marx

    o Criticized due to the classes too limiting

    Postmodernism Emphasizes that multiple perspectives help understand the urban area better

    than having 1 perspective have the say.

    o Visible impact seen in Chicago, Toronto and Berlin

    o Criticized since there can be endless interpretations for a city

    The Origin and Growth of Cities

    Why did non-agricultural settlements arise?

    Why did they get so geographically concentrated?

    Why do some of the urban settlements grow to become larger than other urban settlements?

    REASON: Agglomeration Economies

    economic benefits due to the concentration of activities in the given space

    2 types of Agglomeration Economies

    Localization

    - Closer to similar firms

    - Advantages are : benefit of labor pooling, development of

    industries, relative ease of communication and exchange of

    supplies, laborers and innovative ideas

    Urbanization

    - Locating in an urban environment

    - (Infrastructure, Information, Economies of scale)

    NOTE : Agglomeration Diseconomies

    The term 'diseconomies of agglomeration' refers to the opposite case. Additional competition drives

    downpricingpower. For example, spatially concentrated growth in automobile-oriented fields may

    create problems of crowding and traffic congestion. It is this tension between economies and

    diseconomies that allows cities to grow while keeping them from becoming too large.

    2 concepts important to understand the development of cities

    1) Social SurplusProduction of more basic (city forming) goods than needed for subsistence

    2) AgglomerationConcentration of activities/people/networks of relationships in space

    A surplus trade and specialization B

    Reasons for a social surplus

    New technology

    Environmental change

    Changes in social organization

    Early Urban Development

    Largest city was Rome

    Urbanism spread from Greece

    Planned Greece cities had a gridlock pattern

    Roman cities had the pattern too, in addition to,

    Square/rectangular town perimeter

    2 main cross-streets

    E-W Decamanus

    N-S Cardo

    Middle period Urban Development

    Slowly growing European cities due to decrease in spatial interaction

    Commerce expanded function of cityMercantilism

    Cities became industrial centres

    Industrial and Post-Industrial Urbanization

    Cities became places of population concentration

    Cities became more specialized

    North American Urbanization

    4 phases to the urban development over time

    Stage 1: Frontier merchanitilism

    Stage 2: Early industrial capitalism (internal structures of cities changed)

    Stage 3: National Industrial Capitalism (Central business district in highest cost area)

    Stage 4: Mature Industrial Capitalism (Megalopolis emergence)

    Main megalopoliss: BosWash

    San San (San Diego to San Francisco) & ChiPitts (Chicago to Pittsburgh)

    National Urban Systems

    Allen Pred - Classified according to interdependence and closure

    Settlement patternsoften reflect urban function

    Linear Patterntends to follow roads, railroads (easy access to transport themselves, goods)

    Clustering Patternemerges from smaller settlements around a central focal point (a resource)

    IMPROVES EFFICIENCY!

    Uniform/Hierarchical patternmegalopolisa chain of metropolitan areas

    City-Size DistributionDistribution of urban regions by population

    Has association with: Density of population/activity

    Land value/house value

    Traffic

    Level of social diversity and diversity in services

    2 Types of City-Size Distribution

    1) ContinuousClear pattern between city size and rank within the urban system

    2) DiscontinuousLittle relationship between city size and rank. (maybe due to improper scaling)

    Rank-Size Distribution

    City Size and Rank are directly linked (in reality many cities dont conform to this, although they are

    close)

    Types of City-Size Distributions

    1) Perfect Rank-Size Distribution

    2) Primate City Distribution

    3) Intermediate or Smaller CityDominant Distribution

    Uses of Rank-Size Analysis

    1) Analysis of Temporal shifts in the urbanization process2) Comparison of different urban systems

    3) Forecasting or planning

    CITIES AS CENTRES OF PRODUCTION

    In trying to understand the role of cities as centres of production, three questions / issues can be

    highlighted:

    Why is there a functional specialization among cities (in terms of manufacturing activity)?

    Why are larger cities more economically diversified than smaller cities?

    Why do some cities have concentrations of corporate headquarters while others do not?

    ANSWER: comes from an understanding of how manufacturing (and services) growth is linked to the

    growth of cities and the functions performed by them

    1) Cities as centres of manufacturing and service delivery

    One of the most important components of urban growth

    Classifying Manufacturing places:

    Components or types of goods: durable, non-durable

    Value-added: High-value added (technology), low value added(textiles)

    Stage of the manufacturing process: processing raw material, fabrication, assembly

    Manufacturing Location

    Alfred Webers location Theory least-cost theory of manufacturing location

    Firms would locate closer to input market (market oriented)

    Firms dependent on specific materials would locate closer to it (materials oriented)

    Basically, least cost

    Model too simple, idealistic!

    Why does manufacturing locate in particular areas?

    Needs to be addressed with reference to a broader change in the global economic system

    Manufacturing location change after post-Fordism

    Production linkages underwent technological and organizational changes

    This affected the patterns of production linkages in and between urban systems

    Major changes:emergence of flexible production systems

    Specialized Industrial Networks

    Just-In-Time delivery systems

    R&D and HQ favour large, metropolitan areas (skilled labour, network development)

    Political changes also affected some changes

    Vertical Disintegration: After postFordism, a production process has been broken into several

    companies, each doing a limited subset of activities required to produce final product.

    Vertical DisintegrationInter-firm linkages

    Manual labour (Blue Collar) will be contracted out

    Labour Demand and Supply

    Labour demand arises due to: Globalization

    Industrial restructuring

    Technological Change

    Labour supply as given by: Population growth and dynamics

    Education and Training

    Hours of work

    Labour market Imbalances

    Labour shortage results in: delays in completing projects

    Reduced ability to attract investment

    Labour surplus results in: underemployment

    Underutilization of skills

    Involuntary contract/ part-time work

    Intra-Urban Employment

    Decentralization and clustering of activity/employment

    Decentralization:

    Major industrial concentrations only appear after major transportation infrastructure

    Lower-cost bordering (peripheral) sites are more appealing than central more expensive locations

    Home-work becoming more popular

    Low-density industrial parks are favoured

    ALL LEAD TO PEOPLE MOVING AWAY FROM CITY CORE

    Clustering:

    Occurs due to intensification of ties between firms

    Most seen in central city and older suburbs

    Appeals to ventures that can operate in sub-divided/multi storeyed premises

    For examplemedia and culture industries in Toronto are suited for this. Also close to the creative

    workers

    Informal Economy

    Underground/Black market

    Can distort true market functioning

    Many forms

    Global Cities

    Main sites for capital and investments. Immigrant location. Location of highest-order functions/markets

    Globalization = highest-order functions concentrate in only a few key cities. (Leads to international

    integration)

    Those are GLOBAL CITIES

    Command and control centres of the world!

    Additional notes :

    Gentrificationis a shift in an urban community toward wealthier residents and/or businesses and

    increasing property values,[1]

    sometimes to the detrimentof the poorer residents of the community.

    Gentrification is typically the result of investment in a community by local government, communityactivists, or business groups, and can often spur economic development, attract business, lower crime

    rates, and have other benefits to a community. Despite these potential benefits, urban gentrification is

    perceived to result inpopulation migration,with poorer residents displaced by wealthier newcomers.

    Often old industrial buildings are converted to residences and shops. New businesses, which can afford

    increased commercial rent, cater to a more affluent base of consumersfurther increasing the appeal to

    higher income migrants and decreasing the accessibility to the poor.
