26
What is the Central Business District (CBD)?
The area usually in the middle of a city with most amenities and services ## Footnote The CBD is often surrounded by a ring road.
27
What characterizes the inner city area of most UK cities?
A mix of residential land use with some businesses and recreational parks ## Footnote Short, parallel roads often indicate areas of terraced housing.
28
What are suburbs?
Mainly residential areas towards the edge of the city ## Footnote Often characterized by semi-detached houses and short, curved streets.
29
What is the rural-urban fringe?
The area on the edge of the city with farmland, open spaces, and new housing developments ## Footnote It also includes large retail and business parks.
30
How can you identify different zones in UK cities on a map?
By looking for a mixture of white space and built-up areas ## Footnote Each zone has distinct characteristics that can be visually identified.
31
What does sustainable living mean?
Living in a way that lets people meet their needs now, without reducing the ability of people to meet their needs in the future. ## Footnote Sustainable living also implies not irreversibly damaging the environment or depleting resources faster than they can be replenished.
32
Why is it unlikely that big cities will ever be truly sustainable?
Big cities require so many resources that achieving true sustainability is improbable. ## Footnote However, measures can be taken to enhance sustainability in urban living.
33
What are vital resources in cities that are often not managed sustainably?
Water and energy. ## Footnote Conservation schemes can help in managing these resources more sustainably.
34
What is a key principle of water conservation schemes?
Only as much water should be taken from the environment as can be naturally replaced. ## Footnote This principle helps ensure the sustainability of water resources.
35
List three examples of water conservation methods.
* Collecting rainwater for use on gardens or for flushing toilets * Installing toilets that flush less water * Installing water meters so that people pay for the water they use ## Footnote Encouraging less water use, such as turning off taps, is also important.
36
What is unsustainable about burning fossil fuels for energy?
Fossil fuels will eventually run out and contribute to climate change by producing greenhouse gases. ## Footnote This emphasizes the need for alternative energy sources.
37
What are examples of energy conservation schemes?
* Promoting renewable energy (e.g. wind or solar) * Encouraging energy-efficient homes * Ensuring new homes meet minimum energy efficiency requirements * Reducing car use by promoting public transport ## Footnote These actions help decrease reliance on fossil fuels.
38
What initiative has the city of Curitiba, Brazil, implemented for water conservation?
The installation of water meters in homes and hosepipe bans. ## Footnote Curitiba also has separate systems for non-drinking water.
39
What percentage of Curitiba's water consumption is compared to other Latin American cities?
It is around half that of other Latin American cities. ## Footnote This demonstrates the effectiveness of their water conservation policies.
40
What transportation improvement did Curitiba undertake in 2009?
Renovated its 'Green Line' transport system with dedicated bus lanes for biofuel buses. ## Footnote This initiative aims to enhance public transport efficiency.
41
What energy source does Curitiba primarily use for electricity?
84% of its energy comes from renewable hydroelectric power. ## Footnote This significantly reduces CO2 emissions compared to other cities.
42
What is the reduction percentage of CO2 emissions from electricity in Curitiba compared to other Latin American cities?
About 65% less. ## Footnote This reflects the city's successful energy conservation efforts.
43
What are some reasons that cities can be considered unsustainable?
Cities can be noisy, dirty, busy, and hot, making them unpleasant and stressful for residents.
44
How do green spaces contribute to urban sustainability?
They provide cooler areas, encourage exercise, and improve happiness by offering a break from city noise.
45
What environmental benefits do green spaces provide?
* Reduce air pollution * Decrease the risk of flooding
46
What government scheme did Curitiba launch in 2007 regarding green spaces?
The scheme encouraged landowners to preserve green areas and limited urban sprawl by providing tax exemptions for park creators.
47
What is Barigui Park designed to do?
It is designed to absorb flood waters, eliminating the need for unsightly flood defenses.
48
What is the predicted amount of plastic in landfill by 2050 if current trends continue?
12 billion tonnes
49
What are some consequences of landfill waste?
* Wastes resources that could be recycled * Releases greenhouse gases as it decomposes
50
What are some waste recycling schemes mentioned?
* Kerbside collections of recyclable materials * Building recycling facilities for larger items * Websites like Freecycle™ and Freegle

52
What are some problems caused by traffic congestion in urban areas?
* Environmental problems from increased air pollution * Economic issues from delays * Social problems including higher accident rates
53
What public transport strategies have been implemented in London?
* Docklands Light Railway * London's Underground system * Self-service bicycle hire * Electronic 'Oyster Cards'

What is the purpose of the Docklands Light Railway?
It connects east London to the city centre and is used by around 120 million people each year.
55
How does London's Underground system impact road usage?
