Agribusiness
The Green Revolution
1. Watch Dr Norman clip
2. Read “green Revolution: curse or blessing?”

4. Answer the questions
Link back to all the reasons for sufficiency
So. Green Revolution..
• Where has it led to excess food?
• Where hasn’t taken advantage of it?
• Negatives of the Green Revolution?
Negatives… short termist?
Areas of food sufficiency
• Explain how changes in agricultural
systems, scientific and technological
innovations, the expansion of the area
under agriculture and the growth of
agribusiness have increased the
availability of food in some areas,
starting with the Green Revolution and
continuing since.

Debate - Are economic factors
responsible for food shortages?
Two opposing viewpoints:
• Yes, economic factors are the main cause of food
shortages (although we acknowledge that some
other factors do have a part to play)
VS
• Economic factors have some bearing but there are
other factors that are more responsible for food
shortages
Use your notes on food sufficiency/deficiency as
well as the graphs (fig 10.6, p.263) to help you.
