African City Model
Model that suggests that African cities have more than one CBD, which is a remanence of colonialism
Bid-rent theory

Abandoned polluted industrial sites in central cities, many of which are today being cleaned and redeveloped.
Burgess Concentric-Zone model
This model was devised in the 1920s by Ernest Burgess to predict and explain the growth patterns of North American urban spaces. Its main principle is that cities can be viewed from above as a series of concentric rings; as the city grows and expands, new rings are added and old ones change character. Key elements of the model are the central business district and the peak land value intersection.
Central Place Theory (Christaller)
A theory that explains the distribution of services, based on the fact that settlements serve as centers of market areas for services; larger settlements are fewer and farther apart than smaller settlements and provide services for a larger number of people who are willing to travel farther.

Greenbelts
A ring of land maintained as parks, agriculture, or other types of open space to limit the sprawl of an urban area.
Griffin-Ford Latin America city model
-CBD and the market is based on trade -Market is built through the spine and connects to the mall -Rich people live directly next to the spine (can afford to shop there) -Older buildings around the CBD (ring around it; contains the upper middle) -Slums surround the entire model -Wanna be's live in between the periphery/slums and the rich people (can afford a house, but it's definitely not a mansion) -Surrounded by mountains and rainforests, so slums can't move outwards (they have to move inwards), which creates the disamenity sector -Gentrification is buying older houses and fixing them to be resold -Industrial park surrounded by periphery (the exact opposite direction of rich people)

Slow-growth cities
Urban communities where the planners have put into place smart growth initiatives to decrease the rate at which the city grows horizontally to avoid the adverse affects of sprawl.
Smart-growth policies
An urban planning theory that concentrates walkable city areas to prevent urban sprawl.
Southeast Asian City Model
McGee model. Developed by T.G McGee. The focal point of the city is the colonial port zone combined with the large commercial district that surrounds it. McGee found no formal CBD but found separate clusters of elements of the CBD surrounding the port zone: the government zone, the Western commercial zone, the alien commercial zone, and the mixed land-use zone with misc. economic activities.
