Characteristics of Urban Environments: Chicago

Assumptions: - Assumes a relationship between the socio-economic status of households                         and the distance from the CBD.

                       - Further from CBD, better quality housing.

Central Business District - Tertiary employment and transport infrastructure.

Inner City - Industrial activities to take advantage of nearby labour markets.

Inner Suburbs - Residential zone dominated by working class as low cost location.

Outer Suburbs - High class and expensive, commuting costs are the highest.

Negatives - Too simple and limited in historical and cultural urban context.

               - Model was developed for American cities and has little relevance elsewhere. In                            most pre-industrial European cities, the centre was much more important than the                        periphery.

Characteristics of Urban Environments: Latin

Assumptions: - The larger poor areas reflect the influx of intraregional migrants. 

                    - Gentrification and middle class areas as well as the elite reflect an                                 economy that is improving or allowing some to rise up.

Central Business District - Focus of employment, entertainment and economic activity.

Elite Residential Secor - Forms on either side of a narrow spine that contains amenities attractive to the wealthy.

Zone in Situ Accretion - A mix of middle and low income housing, generally thought of as a transitional area. 

Disamenity - Contains relatively unchanging slums that may not be connected to regular services.

Negatives: Poorer people live on the outside of the city meaning they become stuck in poverty                   cycle. 

Positives: Industry is on opposite side to elite so they don't have to deal with pollution.

Urban Change: Birmingham and Dhaka

Birmingham:

Reasons for Decline - Inadequate services, lack of compulsory education, high housing demand so suburban council estates were built and relocation of poor resulting in sink estates.

Problems with Growth - High levels of air pollution from overcrowded public transport, many high skillled jobs have gone to commuters from the West Midlands and high polarisation in inner ring.

Reasons for Growth - Regeneration in core and inner ring to provide modern services.

Dhaka:

Reasons for Growth - TNCs have been drawn due to cheap labour, growth of informal economy and bostis - illegal shanty towns on land that is unsuitable for development due to high flood risk.

Problems with Growth - 500,000 children work in the informal economy and are exposed to hazards, provisions of services have lagged behind the rise in demand, high death rate due to one third of houses not linked to water supply system and too high rate of urbanisation.

Environmental Impact: London and Mumbai

London:                                                          Mumbai:

Water Supply:

Demand is hard to meet as so high.                   60% of people live in slums and have no access.

Waste Management:

Rising consumption of packaging - disposal.        5000 tonnes produced a day, disposed on roads.

Atmospheric Pollution:

Clean Air Acts to lower emissions furthermore.    Industries cause chronic respiratory problems.

Traffic and Transport:

Congestion charge helps manage traffic.             60,000 road accident deaths a year.

Sustainable Urban Areas: London and China

London: BedZED has nearly 100 houses and apartments as well as offices.

What it does? - Uses 81% less energy for heating, 45% less energy and recycle 60% of waste.

More Sustainable - Cavity walls to store and release heat - South facing homes to maximise solar gain - Using heat from cooking for space heating - ZEDcars for car sharing and free electric charging points - Using low energy appliances - Offices facing north so less need for air-con.

China: Dongtan will be built in 2020, close to Shanghai's CBD and near to the airport.

What it does? - Accomodate new Shanghai Airport, a leisure facility, an education complex and space for high tech industry and housing.

More Sustainable - Powered mainly by HEP - Bus stop at a maximum of 500 metres away from every home - Port to accomodate ferries to and from the mainland.

Problems - Built on agricultural land and will disturb the huge wetland and wildlife refuge.

Nuclear: Europe - 10% of consumption

Oil: Middle East - 50% of consumption

Coal: Asia Pacific - 5% of consumption

6 of 14

Energy Mix: Sweden and Mali

Sweden: Energy use mainly renewable sources

HEP: - 48% of energy generation from HEP  - Power Plants have been built near rivers                          - Harspranget is Sweden's largest Power Station with a capacity of 939 Megawatts

Nuclear Energy - Limited indigenous fossil fuels - 10 Nuclear Reactors that generate 50% of power

Issues: - Local people disagree with power plants near rivers due to pollution

Mali: Relies heavily on imports and less than 12% have access to formal electricity.

Energy Resources: - 80% of energy comes from firewood and charcoal  - 50 million tonnes of forest reserves are cut down every year  - Rechargeable car batteries are used for lighting

Issues: - Lack of electricity hinders the development of income-generating activities.

Renewable Possibilities: - Solar panels on schools from 5-6 hours of sun a day and jatropha seeds for biofuel.

Exploitation Opportunities and Challenges: Norway

Norway: Less than a third of reserves have been exploited.

Social Opportunities: - 80,000 people are employed directly or indirectly  - High incomes means one of the best welfare systems in the world.

Economic Opportunities: - Oil and Gas industry has boosted innovation and technological development in industrial sectors  - Cheap HEP has created jobs and greated a cumulative causation (where one region becomes increasingly the centre of economic activity).

Issues: - Industry is concentrated offshore creating a danger of a major maritime incident.

Nigeria: 6th largest oil exporter.

Oil Related Problems: - Refineries are old and poorly run  - Live on less than $1 a day  - 2003, 70% of oil revenues were stolen or wasted.

Environmental Disasters: - 50,000 acres of mangroves have disappeared from the coast due to land clearing  - Gas flares cause air pollution  - Construction has changed wave patterns.

Social Challenges: - Jobs go to majority ethnic groups  - Violence has increased volatility.

Sustainable Energy: Germany and China

Germany - 30% of energy mix comes from renewable sources.

Sustainable Methods

- 21,500 wind turbines in Germany.

- Excellent weather conditions countrywide made up for 50% of nations electricity through photovoltaic solar panels.

- 9,400 people were employed in HEP

China - Renewables as a source of energy security, not jut to reduce carbon emissions.

Sustainable Methods 

- 3/4 of its wind farms are offshore, accounted for 12.2 GW of generation in 2008.

- In 2007, 820 MW of solar photovoltaics were produced.

- 181 geothermal systems are set up near hot springs with temperatures exceeding 250 degrees.

Attractions = Dunn's River Falls, Dolphin Cave and Blue Mountains.

Benefits: - 20% of its GDP from tourism. Can be spent on essential services boosting overall level of development.

- 220,000 jobs created with tourism. 1 in every 4 Jamaicans employed in industry.

Problems:

Ec - TNCs make most of the money profits (7% of income stays in country)
