Size, growth, developments and function of settlements:

Size, growth, developments and function of settlements Urban and rural settlements

Factors influencing the size, growth, development and function of settlements:

Factors influencing the size, growth, development and function of settlements Extreme environment Areas where food production if favoured Naturally favoured growth Trade and communications Good raw materials Function change overtime

Bid –rent theory:

Bid –rent theory Bid rent concept is the value of land for different purposes, such as commercial, manufacturing and residential . Land at the centre of the city is the most expensive because it is the most accessible land to public transport and there is only small amount available . Land prices decrease away from the central area. Change in levels of accessibility , due to private transport.

PowerPoint Presentation:

Urban settlements have a greater number and variety of services including both low order and high order services. Low order services – services that are often used for example Convenience goods. High order services – services are not needed so often for example Furniture or comparison goods.

Urban land use:

Urban land use LEDC’S (CBD) central business district has developed around the colonial core, and there is a commercial avenue extending from it. It has open areas and parks, and homes for the upper- and middle income classes. These areas have good quality streets, schools and public services. There are suburbs with more housing with fewer services . More squatter housing is found at the edge of the city. Conditions in the city centre are better than areas at the edge and those living near the city centre are closer to centre of employments and more likely to find work. Industrial areas are found scattered along major transport routes.

Land use zoning in LEDC’s:

Land use zoning in LEDC’s The rich generally live close to the city centre whereas the very poor are more likely to be found on the periphery Higher-quality land is occupied by the wealthy Segregation by wealth, race and ethnicity is evident Manufacturing is scattered throughout the city.

Urban land use for MEDC’s:

Urban land use for MEDC’s The Burgess model

Burgess ‘s concentric model:

Burgess ‘s concentric model The land values are highest in the centre of a town or city because the competition is high in the central parts of the settlement . It leads to high rise, high density buildings being found near the CBD, with low density, sparse developments on the edge of the town or city.

The Hoyt model ( sector model):

The Hoyt model ( sector model)

Hoyt’s sector model:

Hoyt’s sector model Emphasized the importance of transport routes and the incompatibility of certain land uses. Sectors develop along important route ways, while high – class residential and manufacturing industry deter each other and are separated by buffer zones or physical features .

Question 2 (exercise):

Question 2 (exercise) i ) Offices/shops/apartments ii ) Amenities such as : water supplies electricity/gas sanitation/drainage heating security cooking facilities air conditioning iii) Location such as: on rural-urban fringe/outskirts/edge of city near centre of city/CBD on steep valley sides/hillsides/steep slopes on marshland/land liable to flood/near rivers near industry/factories

PowerPoint Presentation:

* near low cost housing *near main roads *near rail ways *near waste tips *on direct land iv ) Ideas such as: *Many people migrate from the country side *People are unable to obtain jobs/work for low pay/work in formal sector *cannot afford housing/it is a cheap area to live *As they can build them themselves/ cheap to build *Not enough houses/inadequate government investment in housing * Rates of natural increase are high *easy access to/ close to work
