Transcript

  • 1. What are the problems of rapid urbanisation in poorer parts of the world?
  • 2. Syllabus
    • Key idea:
    • Rapid urbanisation in a poorer part of the world requires the management of the environmental problems caused.
    • Specification content:
    • Difficulties of disposal of waste, much of which is toxic.
    • Effects and management of air and water pollution.
  • 3. Learning outcomes…
    • All will understand that rapidly expanding cities produce large amounts of waste, of varying sorts.
    • Most will understand that there are a variety of ways to try to deal with this waste.
    • Some will understand that some ways of dealing with waste are more sustainable than others.
  • 4. References
    • AQA A pg 210 – 212
    • CGP pg 91
  • 5. Jakarta, Indonesia What problem (linked to rapid urbanisation) is shown?
  • 6. Problems of rapid urbanisation
    • Expanding cities and industrialisation can lead to problems of air and water pollution and disposal of waste.
    • Waste disposal – people in cities create a lot of waste. This can damage people’s health and the environment, especially if toxic and not disposed of properly.
    • Air pollution – burning fossil fuels, exhausts and factories
    • Water pollution – sewage and toxic chemicals from industry can get into rivers and streams.
    • Non-existent or poor regulations and a lack of planning for an environmental emergency make problems worse
  • 7. Waste disposal (1)
    • In richer countries, waste is disposed of by:
    • burying it in landfill sites
    • burning it
    • recycling schemes
    • Poorer countries struggle to dispose of the large amount of waste created by rapid urbanisation because of:
    • Money – simply cant afford to dispose of waste safely – money is needed for more urgent problems e.g. health care
    • Infrastructure – poorer countries don’t have the infrastructure needed e.g. poor road sin squatter settlements mean waste disposal lorries can’t get in to remove rubbish.
    • Scale – the problem is HUGE
  • 8. Waste disposal (2)
    • Waste provides a resource and a means of making a living for many shanty dwellers in poor countries
    • Children and adults scavenge and extract materials and then reuse or resell them.
    • Car tyres may be made into sandals
    • Food waste is fed to animals or used as a fertiliser on vegetable plots
    • Toxic waste and its safe disposal is a key issue in areas where the manufacturing industry is increasing.
  • 9. Electronic waste …
    • Creation of electronic waste is another major problem in a rapidly industrialising country like India
    • In the cities, India’s poor scrape a living by breaking down PCs and monitors.
    • They boil, crush or burn parts in order to extract valuable materials like gold or platinum.
    • What they don’t realise is that the toxic chemicals inside like cadmium and lead can pose serious health risks.
    • India’s hospitals are starting to see patients with 10 x the expected level of lead in their blood.
    • Dumping and unsupervised recycling of e-waste is literally leading to a brain drain
  • 10. What happens to some recycled waste? (3)

    • Britain gives China a toxic shock Sky news 25.11.06 http://news.sky.com/skynews/video
    • Blood sweat and luxuries
  • 11. Your task…
    • Use AQA A book p210 (2nd paragraph) and p211 to make a poster or leaflet to show the issues of waste disposal in LEDC cities.
    • Include:
    • Why waste is a problem
    • What kinds of waste
    • Give some facts and figures about amount of waste
    • What are the dangers for people who try to make a living from waste in LEDC cities
    • What is being done about the problem
    • How successful are these measures?
