  1. Starter What is the world’s most important food source?

  2. Cereals! 2.3 billion tonnes are currently produced annually • 1 billion tonnes for fooduse • 750 million tonnes is used as animal feed • 500 million tonnes is processed for industrial use Source: FAO 2013

  3. What is the correlation between global cereal production and global population?

  4. Learning objectives • To describe patterns in global food supply (production) • To explain why LEDCs have had the greatest increase in production • To evaluate the accuracy of Malthus’ theory using current evidence

  5. The big picture In the last 50 years global agricultural production has increased faster than global population.

  6. The global pattern of food production Production in LEDCs has been increasing faster than developed MEDCs. Why do you think this is? Discuss with your partner…

  7. The global pattern Reasons why production has increased more rapidly in LEDCs: • Higher population growth rates • Increasing GDP / economic growth • Demand has increased greatly as people have become more affluent

  8. Global food production Focus on green, blue and pink! xxx Use an atlas to describe the pattern of global food production. You will need to name specific areas and quote figures!

  9. Recent global trends Between 2003 and 2012 global food production experienced an annual growth of 2.1% (OECD-FAO, 2013). Look at the Figure 6.2 in your textbook (pg. 203). Which regions have had the highest growth in production? • Asia has increased the most, followed by South America. • Parts of Africa have not increased food production due to political instability, neglect of agriculture by governments, and extremely rapid population growth.

  10. What has driven these trends? • The growth in agricultural production is a result of: • Higher yields per unit of land • Crop intensification In the last 50 years global arable land has increased by 67 million ha.

  11. What are the most important crops? These are the world’s most important food commodities. However, sugar is used to produce ethanol fuel

  12. Is Malthus wrong? In 1798, Thomas Malthus predicted that population growth would outstrip the Earth’s ability to feed its population.

  13. Future global trends OECD-FAO predict that food production growth will slow in the next 10 years (to 1.5%), but it will continue to be faster than population growth. Why might this be the case? The main reason is that land available for agriculture is becoming more limited, due to competition for other uses. It is also a result of rising costs for agricultural inputs, such as oil and fertilizer, as well as the increasing scarcity of key resources like water. Much of the 1.5% increase will come from higher yields (more crops per unit of land).

  14. Future global trends: regions Label your world map with the predicted trends in food production growth to 2019: • Brazil – 40% • China – 26% • India – 21% • Russia – 26% BRIC countries will continue to invest in their agricultural sectors to encourage innovation and increase productivity.

  15. Prep Answer the exam question. Next lesson we will review your answers using the mark scheme.
