72
Q

What is the rural-urban fringe?

A

The area of green space that borders the edge of the city

73
Q

SOCIAL: Strong sense of community (local people are involved in local decisions)​

78
Q

Explain two reasons why a city can be seen to be unsustainable

A
  • They ‘suck in’ and consume enormous quantities of resources e.g. water, energy, food and raw materials.
  • They produce enormous amounts of waste. This is usually got rid of in the surrounding land, rivers, sea and air.
79
Q

How might you conserve the environment in a city?

(HINT: historic environment and natural environment)

A
  • Historic: old industrial buildings turned into apartments, rundown housing redeveloped, canals in cities can be rebranded and regenerated as leisure facilities.
  • Natural: more renewable electricity, collect and recycle water (instead of piping it in from reservoirs), run fuel-efficient public transport systems.
80
Q

List ways to improve a city’s sustainability

  1. Provide green space
  2. Recycling water
  3. Reducing reliance on fossil fuels and rethinking transport options

Vital to make cities more sustainable. They act like ‘green lungs’ reducing its impact on the environment by absorbing carbon dioxide and releasing oxygen.

82
Q

Explain how urban living can be made more sustainable?

A
  • Involve local people in decisions for example from where new houses should be built to how local health and social care services are planned and run.
  • Encouragement and availability of recycling waste facilities.
  • Encourage people to generate their own electricity (e.g. solar panels or wind turbines)
  • Provide adequate greenspace
  • Encourage people to use less water / recycle
83
Q

Name an example of a sustainable urban area

A

BedZed - Beddington Zero Energy Development ​

84
Q

  • Low-energy appliances and lighting
  • Energy tracking meters
  • Roof gardens
  • Rainwater harvesting
  • Green transport plan/ car sharing scheme.
85
Q

Describe the ways that water and energy can be made more sustainable in urban areas

A
  • Recycling water so it can be used again e.g. grey water is water that has been collected in households i.e rainwater can be filtered and used to flush toilets
  • using renewable sources to generate energy i.e. solar panels on homes
  • Dual flush on toilets can reduce water used
  • Water and Smart metres make people aware of their energy useable.
86
Q

Describe the ways that waste management can be made more sustainable

87
Q

Describe how creating green spaces is a feature of sustainable urban living

  • Green spaces protect soil which prevents flooding during heavy rainfall
  • Green spaces provide an area for recreation
88
Q

Give some examples of urban transport strategies that have been used to reduce traffic congestion

A
  1. Encouraging people to car share
  2. Oyster cards in London charge people for the cheapest travel

  4. Scratch bikes make it easier for people to hire a bike and use it in no car zones.
  5. London’s ‘congestion charge’ which charges anyone who drives into the centre of London
89
Q

Describe four ways to reduce the impact of traffic in cities

A
  1. Park and ride: drivers leave cars in a car park on the outskirts of the city and bus into the centre so fewer cars in city centre
  2. Bus lanes: Lanes for buses and sometimes taxis only so buses aren’t held up, fewer cars on the roads
  3. Trams: Urban tramways powered by electricity lines so less air pollution.
  4. Congestion charge: People pay to enter certain zones in the city so people avoid this route by car
90
