Why are we doing this?

• .will examine the reasons behind unequal food
  distribution and its connection to health,
  education and the economy
• Examine patterns of global food production and
  consumption.
• Examine soil profiles.
• Examine how desertification, salinization, and
  irrigation have affected food supply.
• Examine the evolution and success of the Green
  Revolution.
• Identify areas of the world where hunger is a
  problem.
• This is a culmination of everything weve been
  doing over the last week.

3
What Does the Information Tell Us?

• Start at square one
• Imagine the world as a blank slate as just
  soil, water and sun.
• Now add in some variables
• What else plays a role in agriculture

4
Chapter 10 Told us What?

• Human Factors Affecting Food Resources
• War
• Debt
• Technology
• Government Policy
• Human Factors Affecting Sea-Based Resources
• Technology
• Government Policy
• Aquaculture

5
Human Factors Affecting Food Resources

• War (p. 245)
• Displaces Farmers
• Prevents cultivation (growing of crops)
• Damages land
• Allocates resources away from agriculture and
  towards military
• Prevents importation of food

6
Human Factors Affecting Food Resources

• Debt (p.246)
• Must spend money to pay down debt instead of
  investing that money into food resources
• Must export resources that could otherwise be
  used to feed population
• Must use land for cash crops instead of setting
  land aside for food crops to feed people of the
  country

7
Human Factors Affecting Food Resources

• Technology
• The Green Revolution
• Increase the supply of food
• Many countries became self sufficient
• But it came at a cost(p. 249)
• Genetically Modified Products
• Goal was to create bigger more resistant foods
• There may be a risk to human and environmental
  health (p. 251)

8
Human Factors Affecting Food Resources

• Government Policy
• Subsidies
• Willingness to trade

Human Factors Affecting Sea-Based Resources

• Technology (p. 253)
• Were able to catch more but the stock of fish
  isnt be replaced any faster.
• Government Policy (p.256)
• Subsidies
• Exclusive Economic
• Aquaculture (p. 258)
• Fish farming
• Increased water pollution, wetland loss and
  mangrove destruction

11
The Green Revolution

• The Green Revolution had an enormous impact on
  the consumption of food resources.
• To an extent, our map illustrates that impact.
• Most of South America and Asia became
  self-sufficient, yet Africa didnt, why?

12
The Good

• Farmers could produce more grain.
• Many nations became self-sufficient in the
  production of grain and could therefore look
  towards producing other, more expensive goods.
• Over the short term famine and malnutrition
  decreased.

13
The Bad

• The increased production of grain had a profound
  impact on the environment.
• Over time fertilizer made the soil less fertile.
• Irrigation techniques caused salinization (salt
  deposits) in soils.
• Pesticides contaminated waters and foods.
• Many farmers couldnt afford all the inputs.
• Loss of biodiversity.
• Increased economic inequality.
• Increased the price of grain products making it
  even harder for the have-nots to produce and
  survive.

14
What else happened?

• There was a massive increase in world population
  because the carrying capacity of the planet
  increased.
• The increased population has also had an effect
  on the environment.

15
Health and Economic Forces

• So what ended up happening to Africa?
• Health
• Plays a big role in production of food resources
• What health issues affect Africa? Could this have
  an impact on the production of food resources?
• Education
• Its hard to get an education when there is no
  one to teach you or when the education system
  doesnt have any resources to draw on
• Economic Forces
• The Green Revolution helped spark a population
  boom which increased the demand for food.
• What happens to the price of goods when there is
  a greater demand for those goods?
• Imagine an auction.

16
What happens as demand increases?
17

• As demand increases so does the price. Imagine
  what happened to the price of grain when the
  population of our planet essentially doubled
  between 1960 and 2008.

18
So

• The map we created is a basic overview of global
  food production.
• Furthermore, the map gives insight into factors
  affecting food production war, politics, health
  and economics.
• To an extent it shows how the green revolution
  has impacted global food production. Some nations
  became productive, others got left behind.
