Flashcards in Changing Urban Environments Deck (84):
1

What are the traffic issues in the city?

-High car ownership
-Narrow roads which lead to serious congestion and high risk of road accidents.

2

What are the pollution problems in the city?

-High pedestrian flow
-High concentration of traffic and restaurants which leads to a poor quality of life and disease may result such as asthma and bronchitis.

3

What are the traffic solutions?

-Improve public transport
-Congestion and toll charge
-Cycling and park and ride scheme, which wll discourage car use and less likely accidents and congestion.
-Multi-storey car parks as well.

4

What are the solutions to pollution?

1.Pedestrianisation (removes car traffic and so pollution level).
2. Plant trees (noise barrier).
3. Preventing (heavy lorries to rescue air and noise pollution).
4. Penalties (for littering and sewage).

5

Why is there ethnic segregation?

1.People feel more comfortable around there own people who speak the same language, religion and same background.
2. Live near important services for their culture (e.g. Place of worship) causes ethnic segregation.
3. Similarly restricted e.g. Lack of money so they all end up in the same place.

6

What are the disadvantages of Ethnic Segregation?

-Xenophobia
-stereotypes
-isolation from experiencing other cultures.

7

What are the strategies to support the Multicultural Mix?

1. Everyone has access (print leaflets in a variety of languages)
2. Improve communication between all parts of the community e.g by involving leaders of different ethnic communities when making decisions.
3. Provide interpreters e.g. Having them in police stations and hospitals.
4. Suitable services to be able to provide the alternatives to support their culture.

8

What is Multiculturalism?

The act of celebrating cultural, ethnic and racial diversity and teaching tolerance.

9

What is segregation?

This occurs when people of a particular ethnic group choose to live with others from the same ethnic group, separate from other groups.

10

What are the urban issues in MEDC's?

CBD, inner city, housing, pollution and congestion and the multicultural mix.

11

What are the push factors in LEDC's?

1. Overpopulation.
2. Natural disasters.
3. Land ownership (small).
4. Overgrazing/over cultivation.

12

What are the pull factors in LEDC's?

1. Expect more comfortable living.
2. Improved employment opportunities.
3. Availability of schools/doctors/hospitals and entertainment.
4. Bright lights.
5. More reliable sources of food.

13

Why does urbanisation in LEDC's lead to squatter settlements and an informal economy?

1.Cities struggle to support population increase.
2. Rural migrants arrive with few skills and items. Therefore they construct temporary shelters out of materials they can find.
3. Temporary settlements grow large and into large squatter settlements on marginal land.
4. New residents may be unable to find work and so seek in the informal economy (e.g. Selling matches).

14

What are the characteristics of squatter settlements?

Overcrowded, lack of amenities, unplanned and poor living condition.

15

Rabid urban growth

Is sustained by a combination of rural urban migrants and natural increase within urban populations.

16

Invasion stage of Squatter settlements?

2. Illegal electricity (dangerous), sanitation still a problem (disease).
3. Community increases, income still low.
4. semi-permanent.

18

Upgrading stage of squatter settlements?

1. Permanent.
2. Handmade tiles and concrete blocks.
3. Some buy electricity, simple sewage system and piped water.
4. Slope managed and regular employment.

19

What are the solutions to squatter settlements?

1.Self help scheme: government provide material and local people build (money saved from labour spent on basic services).
2. Site and service scheme: small rent (spent to provide basic services for areas) and borrow money to buy materials to build or improve a house on their plot.
3. Local authority scheme: funded by the government the temporary accommodation built by residents are improved.
4. Transport improvements and new towns.

20

What is urban decline?

Is the process whereby previously functioning cities or parts of a city falls into disrepair. The area begins to loose business, local economy shrinks, increase in unemployment, buildings and public areas become run down, badly maintained and abandoned. Crime, fragmented families and an inhospitable city landscape often results.

21

What are the MEDC's push factors?

26

What is a city?

A settlement with a built up areas, with a large number of people living there, often with a high population density.

27

2. 80% has no electricity: shorter days, lower income, no heating=disease.
3. 50% unemployment: unable to pay for shelter or bills.
4. PD of 2000 residents per hectare: closeness spreads disease easily.

71

Kibera: Problems 2.

1. Heavily polluted: disease is rife and bacteria spreads easily.
2. High crime rates: victims even more struggle.
3. No toilet facilities: children employed to clean - vulnerable to diseases and loose education.

72

Kibera: Solutions - INDIVIDUAL.

1. Use kerosene lamps.
2. Adults and families teach each other skills to earn money.
3. Since rubbish trucks cannot access they take their rubbish in piles on edge of town or in bags in the river.

73

Kibera: Solutions - GOVERNMENT.

1. Kenya power and lighting company can provide some power.
2. Kibera intergrated water sanitation and management project (WATSAN) built 2.5km low volume upgraded road and 1.8km storm water drains so inhabitant can access the hospitals and clinics in the city.

74

81

Why is Curitiba Sustainable?

1. Reduce car use means less pollution and use of fossil fuels, so environment is not damaged for people in the future.
2. Green space means future generations will still be able to use the open space.

82

Why is Curitiba Sustainable? 2.

3. Recycling fewer resources used and less waste goes to landfill so more resources are available for future generations.
4. Nice place to live as 99% of it's residents said in a recent survey that they were happy with their town.

83

What are the Problems in the CBD?

1. Lack of space and competition as there is a high cost of land forcing smaller retailers out of the city centre.
2. The environmental quality declined, shops and offices moved away due to competition with out-of-town shopping centres, creating derelict buildings vulnerable to vandalism.

84

What are the solutions to the problems in the CBD?

1. High rise buildings to increase floor area.
2. Redevelop zones of decline in CBD.
3. Expansion into old inner city.
