INTRODUCTION—
PURPOSE/ RATIONALE
Economic
thought indicates that people take care of things that they own (and will take
less care of that which they do not own) because a cost which the individual
incurs by wasting something he/she specifically owns is far greater than if
he/she wastes something not owned. This
is true whether of Hershey Kisses, of a favorite item of a student, or even
of large and valuable resources that people use daily. This simple economic concept is often overlooked— the ‘dismal
science’ being seen as merely textbook ideas and not real world.
Yet, decision-making is something that everyone does daily, and it rests
upon ideas of choice and value— strong economic concepts.
Moreover,
as environmental issues are becoming more and more prevalent in the news, in
schools, and in individuals’ concerns, understanding basic components of property
rights and ‘common pool’ concerns will make many environmental questions more
clear. The destruction of the Aral
Sea is a clear example of this “tragedy of the commons.”
By understanding the events that affected the destruction of the Aral
Sea, students will have a striking example from which to begin viewing other
environmental issues closer to their own homes.
RECOMMENDED
GRADE LEVEL/ COURSE PLACEMENT
For
middle and high school students; higher level students will benefit from some
extension of the unit
(see “Extension & Enrichment. The
lessons could be adapted for upper level elementary grades.
OBJECTIVES
Students
will:
·
Know
what a common pool resource is, and be able to identify at least two.
·
As
a group, decide upon a proposal for funding, noting costs and benefits.
·
Discuss
role of government in deciding environmental concerns.
TIME
ALLOTMENT
The
unit can be completed in three class periods.
Parts
A & B -- Day 1. Part C -- Day
2; and Part D/ wrap-up -- Day 3.
Extension
of activities, such as writing practice (part B), student posters (after part
D), etc, will demand more time, as per teacher’s determination.
PROCEDURE
A.
Opening the lesson
1.
Have a bowl/ bag filled with Hershey’s Kisses (or other small, wrapped
treat). Tell the class that each
person may take out as many as he/ she wants, and then should pass it on to
the next student to do the same. There
should not be a limitless supply—perhaps
an average of one or two pieces per student, knowing it will run out.
(Some predictable order of progression would be a good idea—the lesson
will work the same without it, but the class may riot otherwise!)
2.
When the bowl/ bag is empty, examine who got the treats.
Generally the last students in line will be without any, and the first
students will have the most. Why
is this so? Did the last students have any choice? Did the first students?
What choices did the first students have to make?
Would the outcome have been different if students had to pay for their
Kisses? Since no one 'owned' the
Kisses as they were passed around, did that have an effect on students taking
the candies? (The teacher may want
to ‘redistribute the wealth’… or have extras saved away elsewhere so that no
one feels left out.)
B.
Connecting the activity to the individual
1.
Each student should think of one favorite thing that he/ she has.
Since property rights are a key issue in economic decision-making, these
should be objects/ nouns. Ask the
students to write a paragraph or two about this object.
Younger students might focus on description; older students may write
on ideas of how someone else can tell that it is important, how does the student
care for it, etc. If particular
skills of writing/ English are being stressed at the time, this can be dovetailed
into an appropriate style of writing.
2.
Discuss as a class what objects were chosen/ described in writing.
·
If
a classmate asked to borrow this item, would students be willing to lend it
out?
·
What
kind of warnings might the owner give to the borrower?
Why?
·
What
if a stranger asked to borrow the item?
(These
answers can be written on the board as an example of a ‘contract for care’ for
the item in question.)
·
Why
do people make stipulations for borrowing?
·
What
if you found a sweater in the lounge (as opposed to borrow it)—would you treat
it differently?
·
Why
wouldn’t the finder/ borrower naturally be as careful with the item as the owner?
·
To
what other things might this happen?
·
What
are examples of things that no one owns?
·
How/
who takes care of these things?
Teacher
should make explicit connection to the term common
pool resources for the students. Much
of the environment is seen as “collectively owned.”
C.
Real world example: The
Aral Sea
1.
Students should be broken into groups of 4-6 students.
Each group represents a planning committee that will examine and comment
upon a project for economic growth in a specific area (Inner Asia).
If desired, each student can be designated a specific role, such as group
facilitator, recorder, class reporter, etc.
Each
student should get a copy of the case/ project (Appendix I).
Before the groups meet, each individual needs to read the information
sheet, and then individually answer questions about each project.
Groups should then meet, discuss possibilities of the project, and come
to a solution whether each are worthwhile, and why/ why not.
Finally, someone from each group should report the group’s conclusions
to the class.
2. As each group reports to class, was there a consensus as to funding/ not funding? What were the concerns raised? Specifically, the groups’ points should be listed on the board under the headings of “project benefits” and “project costs.”
Looking
at the class’ list of project benefits & costs, discuss:
·
How
did the groups (or individuals) put a cost to the diversion of water?
Who benefits/ pays?
·
What
unintentional secondary effects might come about due to this proposed project?
·
Who
will benefit/ pay from the secondary effects?
·
If,
in the long-run, it turns out to be unprofitable—even disastrous—how could policy
groups have missed predicting such outcomes in their discussions?
·
What
alternatives might there be? Are
there consequences from those choices?
·
How
does this relate to the earlier ideas seen in the Hershey’s Kisses example or
the discussion about people’s favorite items?
D. The Aral Sea & property rights
1.
Distribute
copies of “The Aral Sea Disaster”
(Appendix II) to each of the students.
Let each read over the
real-world effects of the Soviet plan.
Since this is a real case, the class can quite clearly see the outcomes of their
economic plan. Concepts of ownership
and economic value can be used to understand this phenomenon.
Since the environment is seemingly ‘free’ for all to use, often decisions
are made that have many negative consequences for others.
If only two or three people had owned the Aral Sea (the fish & water
supply), perhaps they would have been more watchful of these real costs that they would be incurring.
This
same economic concept can be seen in most environmental issues. For example,
companies may dispose of toxins in a nearby river because it is cheap to do
so: the company gets the benefit of the production, and only pays merely a portion
of the cost (some of the cost is borne by people who used to swim or fish in
the river). Unless the full cost
is paid by the producer (often by government requiring clean-up costs… although
there are other, probably better, courses of action), the pollution will no
doubt continue.
2.
Wrap- up and reconnection
·
How
do students respond to the questions from Appendix II?
·
How
can a person/ committee know the ‘real’ costs of activities?
How should we judge?
(local
participation, evaluation of environment and health as well as money, etc.)
·
How
do property rights affect our decisions?
·
What
are examples of other does “common pool” resources?
·
What
are other examples from the students’ own city or state where this phenomenon
can be seen?
(smog,
noise, graffiti, wasting paper at school, rough use of textbooks not owned,
etc.)
ASSESSMENT
The
lesson is not meant to be lengthy and involve specific assessment itself.
Evaluation should be according to instructor’s choice, but certainly
the definition and example of common pool resources (and solutions to the problem)
are of prime importance. The final
questions (from Appendix II) may be answered in written form by students and
also used for evaluation purposes.
Any
extension to the lesson (see below) would serve as a continuation as well as
possible higher-level assessment for the lesson.
EXTENSION
& ENRICHMENT
An
alternative approach to the final section (examining the specific outcomes of
this project) is to have the class groups find out information on their own
and make posters/ presentations to the class at a later date.
This may work well in higher grades.
Students
can create their own maps, using geography and cartography skills, showing the
location of the Aral Sea, countries affected, ‘before’ & ‘after’ shorelines,
location of water diversion, etc.
This
can also be an entry lesson into a unit on biological/ environmental effects,
sustainable development and other environmental issues, or a study on the Central
Asian region.

APPENDIX
I
You
are a committee member on an important economic development council from an
inner Asian country. You are examining a newly proposed strategy to increase hard
currency (foreign money, such as US dollars) so that your area and country can
start importing goods from other nations.
Before
you start discussing with your committee, you should read the background information
on your region; your entire committee will have this same information. Then, you should read the proposed project, and answer the
prepared questions. This will
allow you to start forming some ideas to discuss in your committee meeting.
You
are an advisor from a large nation (1,050,000 square miles:
the size of AK, TX, and CA together!).
It is a poor area of the world, but with many untapped resources—including
oil reserves, gas, coal, and iron. However,
the country is not yet energy self-sufficient, due to poor infrastructure.
The geography is varied, but generally of continental climate.
There are two large inland seas on its borders (no access to oceans),
and two major rivers which feed these seas (see map).
Population is small (17.5 million people—about the population of TX).
PROPOSAL:
Water for cotton production
A
proposal has arisen which would allow for new farmland to be created. A large dam and irrigation canal system can be built, which
will allow water to be diverted from one of the main rivers to desert land area.
This will cost approximately *** to build.
The new irrigation system, if built, will allow for millions of hectares
to be irrigated and used for crop production.
However, the sea itself will be affected by the reduction of river water
that currently feeds it. There
are fishermen who live along the coast of the sea, and their local economy depends
on them. Yet, by growing cotton,
and perhaps other desired products, the country would then be able to sell the
output on the world market for hard currency.
Moreover, pesticides can be used to increase crop yields to ensure harvests
and profitability. It is estimated
that in the first *** years, $
*** will be produced and sold.
Questions
to consider and discuss:
How
would this proposal allow the country to make money?
What
are the costs involved?
Who
(individuals, groups, others…) might be affected in a positive way by the proposal?
Who
(individuals, groups, others…) might be affected in a negative way by the proposal?
Are
their other issues/ questions that need to be considered?
Does
this proposal sound like something you would recommend to the council/ nation?
(why, why not?)
Now,
meet with you colleagues to discuss the merits of this proposal and if it should
be implemented.
APPENDIX
II
Bodies
of water, whether rivers, lakes, or oceans, are often not seen as “owned” since
we all have some interest in each of them.
Not only water, but the world’s environment as a whole can be seen as
owned in common—people can use (or abuse) it, but there is a price paid for
such use. The cost to these “common
pool resources” is borne by every owner however, not just the person who initiates
the action.
The
Aral Sea is a good example of this phenomenon.
The Soviet government, anxious to find products for export as well as
develop its southern republics, set out on a program of accelerated agricultural
production. The Kara Kum Canal
opened in 1956, which diverted water from the Amu Darya River into the desert
for crop land irrigation. After
1960, the water level of the Aral Sea began to drop.
What
actually happened to the Aral Sea?
The Aral Sea was once a fertile region and the fourth largest lake on Earth. In 1965, the sea was receiving approx. 50 cubic kilometers of water per year from the river inflow. By the early 1980s, this had dropped to zero. The sea has shrunk by more than 70% since 1960; some estimates now show that the entire sea could disappear by 2015.
As
the Aral Sea shrank, its salinity increased, destroying much biological life.
The formerly large catches of fish had declined by over 75% by 1977.
A fishing industry that had supported 60,000 people is ruined.
The
regional climate has also changed. The
growing season shortened as the climate became more continental— and some farmers
switched their crops from cotton to rice (which demands even more water).
Moreover, regional climate changes may have greater effects outside the
area.
The
heavy use of fertilizer and pesticides for the intensive agriculture have quickly
found their way into water and irrigation channels—poisoning the water and food
supplies. Salt, sand, and dust
from the exposed beds of the sea now blow across the region.
With
lack of safe water, the area’s inhabitants face decreasing basic sanitation
and health standards. Less than
60% of inhabitants have access to piped water systems.
Tuberculosis, viral hepatitis, and throat cancer are common.
The majority of children in the area are weak or anemic, and vulnerable
to infections. In Kazakhstan’s
Kyzyl-Orda region, 80% of the population (660,000) are said to be ill.
Uzbekistan has been trying to reverse some of the consequences from the Aral Sea’s degradation. In the late 1990s, a multi-targeted project began, costing $117 million. This money came not only from the Uzbek government but also from loans by the US, Germany, Kuwait, and the World Bank.
