infer for the future?

The estimated world population in 2005 was 6.551 billion
people. Using the regions above, estimate how many people
lived in each region in 2005 to nearest million people.
(that's 6,551 million people in the world!)

Looking at the population growth figures, make predictions about which areas
of the world are going to face pressure on their resources in the future...

Look at the overall cereal production in 2005, and
how much production of cereals has increased in
each region since 1961.....
Four Factors to Compare....
a)
b)
c)
d)
Population as of 2005
Population increase patterns over the last half century
Cereal (food) production as of 2005
Cereal production increase patterns over the last half century
Considering the above statistics and patterns, what issues
may arise over the next 50 years when it comes to food and
food distribution in various regions around the world???
Fill in your "Food Production and Speculation Matrix" as we go

America
Ability to Trade
Surplus Food
- has enough food
for population, will
have enough over
long term based on
population growth
- no pressure to

Need to Trade to
Get More Food
- food production
patterns show that
they will likely have
surplus food to trade
for other goods

Is there enough food???
It has been argued that there is enough food produced in the
world for its current population. Yet, chronic malnutrition is
epidemic in many parts of the world.
On the next slide, redistribute the food production (cereal) in
the world to the global population so that everyone has an
equal amount of food AND it is enough to meet basic needs.
**The numbers used in this exercise are approximate values based on 2005 statistics**
According to the Canada's Food Guide to Healthy Eating, the
average adult would need 75kg of cereals and grains per year
to meet a healthy, minimal diet.
Using the population figures from earlier, how much cereal would be
needed annually to meet the needs stated in Canada's Food Guide
(based on 2005):
1,000kg = 1 metric tonne

Based on your work redistributing the cereal food
production of the world...
A) What conclusions can be drawn from the exercise
about food production and distribution in the world?
B) What factors may influence the lower production of
food in areas of high population (i.e., South-Central
Asia, Sub-Saharan Africa)?
C) What role may agricultural technologies and
access to those technologies have on the food
production and distribution issue?

Active Citizenship:
INVESTIGATE some organizations and charitable
groups that work to improve farming technology and
greater equality in food distribution around the world.
PARTICIPATE in an awareness campaign or lobbying
your political leaders to address the issue of unequal
food distribution and supporting the improvement of
farming technologies in poorer nations.
DEBATE the issue of food distribution and trade in the
world by discussing the solutions and greater
challenges to these issues.
