  • 1. Global Population A2 Geography
  • 2. What are the Challenges?
  • 3. Reducing Disparity <ul><li>In 1900 approx. Two thirds of the 1.5 billion people on earth lived in LEDC’s today the figure is more like three quarters. 90% of babies born are born in LEDC’s. Of the 4.8 billion living there: </li></ul><ul><li>60% lack basic sanitation </li></ul><ul><li>30% without clean water </li></ul><ul><li>25% have little or no adequate housing </li></ul><ul><li>20% No access to health services </li></ul>
  • 4. Cutting Consumption <ul><li>More food needs to be produced – made worse by these people being born in LEDC’s </li></ul><ul><li>LEDC’s struggle to produce the quantity of food </li></ul><ul><li>Demand is increasing due to rise in number of households </li></ul><ul><li>People living longer </li></ul><ul><li>Family break up – Biggest in MEDC’s </li></ul><ul><li>MEDC’s require more resources than LEDC’s </li></ul>
  • 5. Saving the Planet <ul><li>Effects on environment from growing need for resources </li></ul><ul><li>Movement into marginal and wilderness areas </li></ul><ul><li>Use of Non-renewable resources in MEDC’s </li></ul>Figure 1. Species Threatened with Extinction as a Percent of Total Number of Known Species
  • 6. Easing the Flow <ul><li>Migration and its reasons have been around for millions of years often triggered by: </li></ul><ul><li>Hazards </li></ul><ul><li>Wars/ Conflict </li></ul><ul><li>Overuse and abuse of environment </li></ul><ul><li>Famine </li></ul><ul><li>Oppression </li></ul>
  • 7. <ul><li>One in every 200 people is now a refugee </li></ul><ul><li>Whilst migration could bring about more equality it is a hot political issue </li></ul>
  • 8. Shrinking The Family <ul><li>Though less to do with Geography than sociology it is important for the future of the planet </li></ul><ul><li>BR fell by a third during the 20 th century </li></ul><ul><li>DR fell by half </li></ul><ul><li>Therefore NI remains high </li></ul><ul><li>World needs lower fertility rates </li></ul><ul><li>Population needs to be stabilised </li></ul><ul><li>BR higher in LEDC’s </li></ul><ul><li>Need for education, birth control and gender inequality </li></ul>
  • 10. Activity 1 <ul><li>Discuss in groups which is the most important in your eyes? And then rank them in the order of importance. Justify your conclusions </li></ul><ul><li>What links are there between wealth and resource consumption </li></ul><ul><li>How do MEDC’s adversely affect LEDC’s </li></ul><ul><li>Suggest a recent event that has increased migration </li></ul>
  • 11. POPULATION <ul><li>Components of Population Change </li></ul>
  • 12. Inputs and Outputs
  • 14. Activity 2 <ul><li>What happens when Inputs exceed Outputs </li></ul><ul><li>When Outputs exceed inputs </li></ul><ul><li>Which is the most important element of population – Justify your view </li></ul><ul><li>Give examples of places that are experiencing the following: </li></ul><ul><li>Natural Population decrease </li></ul><ul><li>Net outward Migration </li></ul><ul><li>Stationary population </li></ul><ul><li>High rates of population growth </li></ul>
  • 15. Activity 3 <ul><li>Find the definitions for the following terms </li></ul>TERM MEANING Crude Birth Rate Standardised Birth Rate Crude Death Rate Standardised Death Rate Fertility Rate General Fertility Rate Infant Mortality Rate Life Expectancy Natural Increase
  • 16. Homework <ul><li>Give justified reasons for the population changes on the map provided. </li></ul>
