More Ideas of Urban Development

Galactic (Peripheral) Model Created by Chauncey Harris (one of creators of multiple nuclei)

Galactic Model Goes with the development of sprawl So all of the traits of sprawl go with the outside of cities with this model – single-use zones – low density development of buildings (single story buildings more prevalent on the fringe) – edge cities would exist on the outside which are a more built up suburb – highways are used for travel and make the development of the periphery possible

Decentralization of the CBD – Shopping and businesses start to go out to the suburbs (edge cities) – Also indicates a movement of jobs to the periphery – City loses some of its middle class and has a prevalence of lower class giving it issues – Population grows on the outside of the city / Suburbs now a larger percentage of the population that people living in the cities.

Rank-Size Rule Defined: the country’s nth-largest settlement is 1/n the population of the largest settlement In other words – the second largest city is ½ the size of the largest

Primate City The leading city of a country. The city is disproportionately larger than the rest of the cities in the country. (Some books define as – The largest city…) For example: London, UK Mexico City, Mexico Paris, France - the rank-size rule does not work for a country with a primate city

Primate City These cities tend to represent the perceived culture of the country.

World Cities

Megacities Large cities characterized by both primacy and a high degree of centrality within their national economy – population of 10 million+ Fastest growing cities are not in core regions

Global Urban Models

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) In Situ accretion: where less expensive homes and businesses seem to be in a chronic state of ongoing construction and renovation

Buenos Aires, Argentina

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

The African City (de Blij model) North African cities Muslim influences. Sub-Saharan major cities developed by European colonizers

deBlij North African City Model Mosque in center Has open air markets Walled cities Courtyards with high walls for each family compound

Tripoli, Libya Somalia Biggest City: Swaziland Tunisia

Southeast Asian City (McGee model) Most major Asian cities developed by European colonizers on ports. Alien commercial – typically Chinese & Indian
