9
Q
What factors affect settlement?
A
- flat land - easier building & space to expand
- dry point - higher, dry land above wet ground
- in a gap between hills - convenient routeway
- road junction - direct routes to other settlements
- in a valley - natural routeway, fertile land for farming
- near to a spring - provide reliable water supply
- river confluence - (joining of 2 rivers) - doubles chance to use natural transport routes
- river bridging point - where river is narrow enough to build bridge
- near woods - source of timber for cooking, heating, building, tools, furniture
- by a river - water for drinking, washing, power, transport, fishing
- sheltered coast - protected harbour can be built (for trade/fishing)
- river meander - bend in river provides natural defence
- higher ground - easier to defend & drier land
10
Q
settlement site
A
piece of land where a settlement is built
11
Q
Why have functions of settlements diminished?
A
technological advances allow us to overcome difficulties
12
Q
situation
A
position in relation to surrounding human & physical features
13
Q
What are the opportunities in Rio?
A
- economy/port - many large companies e.g. Petrobas, have headquarters in Rio & use port for in/exports, provides jobs & improves economy through multiplier effect

- lack of services - lack access to healthcare, education, refuse collection & space for recreation due to lack of investment
- transport congestion - lots traffic is on poor quality roads causing severe congestion, accidents, noise, air pollution
- rural-urban migration - experienced rapid growth & urban sprawl due to rural-urban migration, in search of jobs, pressure on services & amenities
- infant mortality rates - 50 per 1000 in favelas, 12 per 1000 national rate
- lack of education - high unemployment rates & low education rates due to school only being free until 13
15

A
- poverty - more than 1.2million live in favelas (20% population) on less than £1 per day
16
Q
What are the environmental challenges in Rio?
A
- transport congestion - lots traffic is on poor quality roads causing severe congestion, accidents, noise, air pollution
- rural-urban migration - experienced rapid growth & urban sprawl due to rural-urban migration, in search of jobs, pressure on services & amenities
17
Q
What are the solutions to traffic congestion in Rio?
A
- Maestro system - cameras, speed checks, radio links, steet light control & control centre, cameras get live images of road & traffic junctions allowing for real time adjustment of traffic signals, improving traffic flow

- public transport - main form is bus, run more frequently during rush hour, almost 440 municipal bus lines, serving over 4million passengers each day, plus intercity lines
18
Q
What are the solutions to urban sprawl in favelas in Rio?

23
Q
What is urban strcuture?
A
distribution of different types of land uses in a town or city
24
Q
What is the burgess model?
A
series of concentric rings
starting in the middle the rings are:
CBD
inner city
inner suburbs
outer suburbs
rural urban fringe
25
What assumptions are the Burgess Model based on?
- cities grow outwards - become newer as you move away from original site in the city centre
- land costs are higher in the city centre
26
What is bid rent theory?
most expensive land is found in the CBD & land prices become cheaper as you move away from the city centre, land prices are therefore cheapest in the rural urban fringe
27
What are the characteristics of the CBD?
- indoor shopping centres
- department stores
- blocks of flats due to expensive land prices so developers build up rather than out
- theatres & entertainment
- administrative buildings (e.g. town hall, local council)
- business & office blocks
- any open space may be used for parks/sports centres
- multistory car park
- pedestrianised roads
28
Why does the CBD have a large sphere of influence?
- they have high order services & sell high order goods
- they have specialist shops & sell comparison goods
- people travel a long way to use them
- they have larger stores
- they are easily accessible/ centrally located
- other high order services/ tourist sites nearby
29
What are the characteristics of the inner city?
- terraced housing - no driveways/garages/gardens (sometimes yard)
- old warehouses that are no longer in use
- brownfield sites - areas that have been previously developed
- football stadiums
- some inner city areas have been redeveloped
30
What are the characteristics of the suburbs?
- semi detached/detached housing with gardens (front & back), driveways & garages, houses are larger than land is cheaper
- local shops an services
- parks
- schools
- supermarkets
31
What are the characteristics of the rural urban fringe??
- airports
- business parks
- allotments
- golf courses
- new housing estates
- shopping centres
- greenfield sites - sites not previously developed on
- cheaper land
32
Why should you build on the rural urban fringe?
- cost of land is significantly cheaper
- space for expansion
- infrastructure is improving & less traffic congestion than the inner city
- greenfield sites have not been previously built on, so don't need to pay for demolish of what previously was there
33
What is the Hoyt Model?
Circle with different sections coming out
34
Why does the Burgess Model and the Hoyt Model not work for LEDCs?
in LEDCs, high class residential area is close to the city centre & low class is on the periphery (opposite of MEDCs)
35
What are the similarities & differences between the LEDC & the MEDC urban land use models?
similar: both have CBD
difference:
- in CBD competition for space & traffic is worse in LEDCs
- in MEDCs wealthy live in area after CBD, in LEDCs this is where the poorest quality housing is
- shanty town found in area furthest away from city in LEDCs
- industry was originally found in the inner city zone in MEDCs but now it has moved
36
What is a settlement?

isolated dwelling
hamlet
village
small town

46
What is a sphere of influence?
area surrounding a settlement that is affected by the settlements activities, larger settlements will most likely have a greater sphere of influence
47
What are low order services?

50
What are high order services?
services that people don't need regularly e.g. leisure centres
51
What are high order goods?
more expensive items people don't need regularly, often comparison goods, where people often research lots of options to find best deal for them
52
Why do people travel further to access high order services & goods?
- less available
- so they have better choice
- for better quality product
- if shop/service is used that often
- for more expensive things
- trying to find a specialised service
53
Threshold population
number of people needed to support business or service
54
What factors may affect the size of a threshold population?
- wealth of community, wealthier can afford to buy more goods & services so fewer people needed to make the service viable
- not all people share same interests/needs - e.g. retired have different needs to young
- communities have different preferences & traditions - e.g. baker in france may thrive with only 600 people but in england may struggle
55
What characteristics do high order settlements have?
- large population
- high order services
- sell comparison goods
- have high density population
- good communications
- government buildings
- headquarters of large companies
- large sphere influence
- fewer in number & more spread out
56
urban sprawl
rapid expansion of an urban area into surrounding area, often without planning
57
urbanisation
increasing proportion of people living in towns & cities
58
favelas
