URBANISATION
- 1. Very slow growth with most people employed in agriculture (
Rural Society phase)
- 2. Increase in the rate of urbanisation alongsideeconomic
development (Take-off phase)
- 3. Rapid rise in urbanisation - rural-urban migration +
suburbanisation
- 4. Urbanisation slows considerable -the majority live in
towns/cities+ are employed in industry& services
- 5. Counterurbanistion + commuting
- 6. Re-urbanisation + urban renewal
10. URBANISATION
- Rural urban migration is greater than urban to rural
- Life expectancy & natural increase are greater in urban
areas
- Problems create by rapid urbanisation:
- Insufficient housing homelessness squatter settlement
overcrowding lack of tenure
- Strain on health, education & welfare services
- Traffic congestion & pollution
- Unemployment rise inthe informal sector
11. SUBURBANISATION
- = the process by which people, factories, offices and shops
moveout of the central area and into the suburbs
- Factors leading to Suburbanisation:
- Development of transport networks
- Improvements in technology
- Filtering & life stage changes
12. DIFFERENCES BETWEEN GROWTH & SPRAWL
- URBAN GROWTH = an increase in the absolutenumberof peopleliving
in an urban area
- URBAN SPRAWL = An increase in theareacovered by urban
activities
13. PUSH & PULL FACTORS
14. COUNTER-URBANISATION
- =The movement of people away from towns
- and citiesto live in villages & small towns in the
countryside
- Development of dormitory settlements
- Increasing property prices (executive homes)
- Conflict -newcomers & traditional residents
- Change in village population structure
15. RE-URBANISATION
- =The process whereby towns & cities
- which have been experiencing a loss of population are able to
reverse the decline
- Some form of city centre redevelopment is often the catalyst
that starts
- Planned initiatives such as UDCs
- Other development/renewal schemes

- Lacks range or depth to the answer. May wander off focus
- Level 14 - 1One or two basic ideas. General with virtually no
examples
28. IN THE EXAM:
- Read the question carefully
- Brainstorm possible ideas & examples to include
- Try to sequence them so you can write efficiently
- Try a simple one line plan to get you started:
- Examine the consequences of rapid growth in a named LEDC city
Bangkok
- River & air pollution- Traffic congestion Subsidence
Unsustainability Temp. housing under road bridges social problems
reliance on NGOs attempts at management
29. Example 1 - Examine the consequences of rapid growth in a
named LEDC city.
- There are too many people for the amount of land available
& not enough housing for the people, so Mexico City people
lived on the roofs of other houses. Squatter settlements form where
people will build houses out of materials they can find. These are
so numerous that they become out of control. The authorities cannot
cope with the amount of people living there, and subsequently the
amount of waste they produce. Whereas in some areas of Mexico City,
the squatter settlements are built on hilly areas, the land becomes
unstable and collapses, taking homes and people with it.
30. Example 2 - With reference to specific examples, examine how
the quality of life has been improved for residents in LEDC
cities
- Mexico City has tackled its traffic problem by the introduction
of a scheme where cars with certain registration numbers cannot
drive on certain days of the week, which reduces pollution and
congestion. They are also spending 1m to extend the Metro line to
carry 4 million/hr during rush hour, and improving the bus service
to be more efficient, cheaper, cover a wider area, and hopefully
reduce pollution from cars.
- In Cairo, they are managing the problem of housing provision
for the expanding population, (2000 per week), by building
satellite cities such as 10th Ramadan and Sadar City, (which will
house up to 30 000 people). They are also legitimising the illegal
occupation of land, (in shanty towns and tombs in the City of the
Dead),providing electricity to the area and increasing the number
of green spaces in the city
31. Example 2 -With reference to specific examples, examine how
the quality of life has been improved for residents in LEDC
cities
- Providing clean water also decreases the spread of diseases
such as cholera. They have also improved the sewage system via the
Greater Cairo Waste Water Project. This is a drainage system to
collect water and take it out to the desert to irrigate farmland.
Cairos authorities manage the rubbish collection by licensing the
Zabbalean people to collect, clean and recycle rubbish.
- In Curitiba, Brazil, they pay individuals to collect rubbish in
carts and sell them torecycling companies. Public transport is
comfortable and drivers are paid by the amount of km. they drive
not by the amount of passengers, so they are encouraged to visit
all parts of the city.
32. Example 3 -With reference to a named city, examine why large
urban areas are unsustainable
- Cities are usually unsustainable because of their growing
population and everyones demands for resources and for the dumping
of waste. Mexico City is surrounded by hills and pollution, largely
from car emissions, becomes trapped above the city and is a serious
danger to health, especially lung disease, (just like smoking
around 40 cigarettes per day). Solid waste is a big problem: 11 000
tonnes of waste is produced but only 9000 tonnes collected. This
waste ends up in waterways and streets, (2000 tonnes of waste is
dumped in the Penuco River each day). Mexico City is growing
uncontrollably, (60% through natural increase and 40% through
rural-urban migration), and it now has a population of 26m.
33. Example 3 -With reference to a named city, examine why large
urban areas are unsustainable
- .This causes huge problems for the quality of life of migrants
on the outskirts of the city: a third have no sanitation and live
in one room. Mexicos Federal District produces 28% of the countrys
industrial output and contains 40 000 factories. This adds up to
the transport pollution, producing 12 000 tonnes of noxious gases
released into the atmosphere each day. As areas expand it becomes
difficult to co-ordinate a sustainable infrastructure, waste
disposal, etc. By damaging their environment through pollution,
etc, the area is made unsustainable because future generations will
not be able to meet their resource needs.
34. Example 4 -With reference to a named large urban area,
examine the factors that influence the spatial pattern of land
use
- Middlesborough grew into a large town with the Industrial
Revolution and the discovery of iron ore on Eston Moor which, in
turn, led to the development of the iron works. People moved to the
town for jobs. In 1851 the population was 8100; in 1921 it had
risen to 120 000. After that it was well known for its chemical
industry and the main industrial area was situated close to the
river for transport. Both of these industrial developments promoted
the growth and expansion of the city. However, growth has been
restricted by the River Tees running through the heart of the area.
The town can be compared to the Hoyt model with different sectors.
The CBD contains the most expensive land and the Bid Rent theory
suggests that high profile businesses and retail will be able to
afford to locate there..
35. Example 4 -With reference to a named large urban area,
examine the factors that influence the spatial pattern of land
use
- ..They will out-bid other land uses in order to obtain
accessible and busy sites. Adjacent to this area is the Iron
Masters District developed in the 1830s. Originally linked to the
iron industry it has recently experienced gentrification as younger
couples see the potential of the location with original features
combined with a proximity to the CBD services. There is a general
decrease in the age of the areas from the River Tees towards the
regions of Drysome and Kirby. This is where the more wealthy people
lived and this fits with the model that higher quality houses are
located away from the city centre, where the oldest houses are. In
the 1960s council estates in the Pallister region were built and
the slums of the old iron masters district were knocked down and
redeveloped. The industrial sectors are bisected by the River Tees
which fits the model that industry sets up on roads and
railways
