Transcript

  • 1. Changing Urban Environments
  • 2. What are the Characteristics of Urbanisation?
    • Lesson 1
  • 3. Lesson Objectives
    • All will understand what we mean by an urban area and the process of urbanisation.
    • Most will understand how urbanisation has varied throughout the world and over time.
    • Some will be able to identify, describe and compare trends from maps and graphs.
  • 4. What is an urban area?
    • As you watch the video, write down words to describe an urban area
    • http://www.youtube.com/watch?v=uyaj2P-dSi8
  • 5. What is urbanisation?
    • A process where an increasing proportion of the population lives in towns and cities (and consequently there is a reduction in the number of living in rural areas)
  • 6. Rate of urbanisation
    • In 1950 fewer than one person in three lived in a town or city
    • Today half the world’s population live in an urban area … by 2015 the proportion will be 60%
    • In 1950 New York was the only global megacity …. By 2015 there will be 27 megacities …. 21 of them will be in Asia
  • 7.
    • Urbanisation is generally linked with economic development.
    • As a country moves from a mainly rural agricultural economy to a more industrial, commercial economy, the population becomes increasingly concentrated in towns and cities.
    • Countries that have reached high levels of economic development usually have an urban population of over 75% of the total population and rates of urban growth are low.
  • 8. Global Trends in Urbanisation
    • Urbanisation is a global process, but it is occurring at very different rates in different parts of the world
    • Stick the graph into your book, label it “Urban Population 1950 – 2030”
    • Describe the trends shown by each of the lines. Support your answer with evidence from the graph. The best answers will give evidence to support the trends you identify
    • e.g. In 1950, The level of urbanisation in the least developed countries was only 8%. By 2050…
  • 9. In which countries do you think most people live in urban areas?
    • Try to predict 5 countries in the world where most of the population live in urban areas, and 5 countries where a low percentage of the population do.
  • 10.
    • Shape in your map to show differing levels of urban population in different countries. Try to label at least 3 countries with a high percentage of population in urban areas and three with a low level.
  • 11.
    • Describe the patterns shown by the map. Try to select areas where rates are very high, average and very low.
    • The best answers will give general trends – is the population more urbanised in the north or the south? In Africa or Europe? Note any exceptions to the trends you identify.
  • 12. Lesson Objectives
    • All will understand what we mean by an urban area and the process of urbanisation.
    • Most will understand how urbanisation has varied throughout the world and over time.
    • Some will be able to identify, describe and compare trends from maps and graphs.
  • 13. Plenary
    • True or false?
    • Urbanisation is the growth in the proportion of a country’s population living in urban areas
    • More than 50% of the world’s population currently live in urban areas
    • The rate of urbanisation differs between richer and poorer countries
    • More than 80% of the UK’s population live in urban areas
    • Most urbanisation is occurring in poorer countries.
