Where are Cities Located and Why? Site and Situation Site * 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. Trade area Trade area – an adjacent region within which a city’s influence is dominant. 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 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. Hexagonal Hinterlands How are Cities Organized, and How do they 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 purposes (functions). 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) Modeling the North American City Concentric zone model (Ernest Burgess) Sector model (Homer Hoyt) Multiple Nuclei Model (Chauncy Harris and Edward Ullman) Three Classical Models of Urban Structure Concentric Zone Model Sector Model Multiple Nuclei Model Edge Cities Suburban downtowns, often located near key freeway intersections, often with: - office complexes - shopping centers - hotels - restaurants - entertainment facilities - sports complexes Urban Realms Model Each realm is a separate economic, social and political entity that is linked together to form a larger metro framework. 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) Latin American City (Griffin-Ford model) Disamenity sector – very poorest parts of the city eg. the favelas of Rio de Janeiro, Brazil The African City (de Blij model) African cities Colonial cities set up for political and economic reasons Administration Set up strategically for exploitation of resources Transportation Near resources African cities Colonial cities segregated by race and religion Divide and rule Some cities designed for European colonialists only South Africa implemented strict segregation laws limiting African access to cities African cities Cities grew rapidly after independence Lagos760,000 in 1960 Over 12,000,000 today Kinshasa 450,000 in 1960 4,500,000 today This rapid growth has created growth of slums and informal settlements Southeast Asian City (McGee model) How do People Make Cities? Powerful social and cultural forces shape the character of a city and create the cultural landscape of the city. Making Cities in the Global Periphery and Semiperiphery - sharp contrast between rich and poor - Often lack zoning laws or enforcement of zoning laws 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.” 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. Gentrification Raises prices of houses in the neighborhood What problems could this cause? 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. Urban Sprawl 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 Celebration, Florida Celebration, Florida Gated Communities Who are gated communities for? How do the goals/purposes of gated communities differ across the world? Ethnic Neighborhoods European City eg. Muslim neighborhoods in Paris Cities of the Periphery and Semiperiphery eg. Mumbai, India Mumbai, India What Role do Cities Play in Globalization? 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. 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
