Description: Students
will learn the effects of population growth on water availability, water
quality, conservation, and distribution. They will explore ways to improve
the water problem that results from population growth. Students will explore
the issues concerning urbanization, the future of agriculture, and conservation
methods in different geographic resions.

Science:
- Discuss what affects population growth has on the water cycle
- Learn how population growth of humans has an affect on all organisms
and discuss what needs are not met for all organisms because of lack
of water availability
- Discuss what nutrients and other needs are also not met due to poor water
quality and talk about what nutrients are needed for water to be considered
"quality."
Environmental Studies:
- Discuss the affects of poor human habits on water quality
- Discuss how industrialization, urbanization, and other results of
population growth are polluting our atmosphere
History:
- Discuss past issues that resulted from population growth
- Track trends in growth over time and see how the problem has progressed
to today
- Find information about past behaviors and see how people in history used
water and what methods if any were used to conserve the water
Geography:
- Explore different regions focusing on the history of the area, population
growth over the past 5 decades (dividing each decade into separate components
to see a trend)
- Focus on regions' water supply and use (where the water comes from,
what it is used for, who uses it)
- Water level
- Water quality
- Upstream/Downstream issues
Math:
- Create a chart relating to the tracking of trends over time
- Use percentages
- Totals
- Other statistics
- Number of people.Amount of water used/saved
- Average growth per decade
- Average rainfall.sufficient to meet population?
- Amount of water available at certain times.The average amount of water
available during certain decades, etc.
- Use similar statistics as above to prepare mathematical data with or without
a chart
Economics:
- Monitor the affects of water quality, water scarcity, conservation, and
distribution on the local, national, and world economy
- How do the water issues that affect food production affect the economy?
- Discuss how water becomes a monetarily consumed item and the lack of
availability can increase the price of water (bottled, tap, etc.) and
in turn can help or hurt the economy depending on consumption
- Companies taking advantage of the water crisis to market and gain
- Other countries with poor or low supplies relying on other countries
with more water available and better quality
Behavioral:
- Discuss how human actions are the cause of the water crisis
- Cover topics relating to ways to conserve and how to educate

Teaching
Preparation
Dr. Mark Rosegrant, senior researcher at the International Food Policy Research
Institute cautions us about our water useage stating, “Unless we change
our policies, in 20 years, there won’t be enough water for cities,
households, the environment, or growing food.” Water is not like oil.
There is no substitute. If we continue to take it for granted, much of the
earth is gong to run short of water or food-or both.”
A major issue that lies within our current water crisis is the constant
population growth in all areas (rural, urban, local, world-wide). According
to he “Global Water Outlook for 2025: Averting an Impending Crisis,”
“Due in part to rapid growth and urbanization in developing countries,
water use for households, industry, and agriculture will increase by at
least 50 percent in the next 20 years. With the increase in population comes
the increase in businesses, homes and neighborhoods, agricultural needs,
and recreational facilities.
According to the Food and Agriculture Organization of the United Nations
(FAO), by the year 2030, more than 8 billion people will inhabit the earth,
requiring 60 percent more food than today. Since agriculture is the primary
user of water, increasing crop production means withdrawing more water from
our finite and already strained supplies. This increase leads to a greater
demand for water with decreasing supply, more chemicals and pollutants in
the water supply decreasing the quality, and a greater need for educating
citizens in reference to environmental concerns and conservation.
Discuss how population growth can affect the water supply in a way that
also affects agriculture ("water use will increase by at least 50% in
next 20 years due to population growth and urbanization, household use,
industry, and agriculture; Increased competition
for water will limit the availability of water for irrigation which in
turn will constrain the world's food production)

Student Activity
- Students should (individually) research a particular region of the
world (from a list prepared by the teacher). The majority
of the information should come from the Internet.
- Suggested research topics:
i. Any endangered species and/or organisms resulting from that area's water
crisis
ii. Any urbanization projects or industries affecting the
environment, or with the potential to affect the environment
iii. History of population growth and water availability in that region
iv. The amount of bottled water consumed, imported,
or exported
v. Identify the conservation methods that the region currently supports
been any conservation efforts
vi. The quality rating of the water in that area
vii. Amount of water used on average, by individual, industries, agriculture, etc., in the region
- Upon completing the research students should prepare a PowerPoint
presentation or an essay to share with the class.
- Students should be responsible for researching outside of class. At least half of the class period should be devoted to research and discussion
of relevant findings
- As a class have students bring in local, state, national, and world
news papers, magazines, articles (Web or print) relevant to the global water crisis.
- Students should compare and contrast the problems in different areas
- See how much of the publications is devoted to the water crisis
- Use at least half the class to discuss findings and relate
them to the lesson
- Have students research relevant Web sites and
prepare a brief synopsis to present to the class.
- Have students go to Web sites of different organizations advocating
or opposing water crisis and see what is being done
to promote their cause. Have students contact the different organizations
via e-mail or written letter, either to express interest, give opinions,
or ask questions about that organization's position.
- Home State Water Issues:
- Divide students into groups and have each group choose one
of the regions into which your state can be divided (i.e. North Carolina can be divided into three regions: Mountains, Piedmont, and Coastal
Plains)
- Each group should utilize the Internet and other publications
to research the following information about each
region. Students will use this information to create a multimedia presentaton on their respective region.:
i. The history of the area
ii. The population growth and trends over the past five decades recording trends
in each decade and make predictions for the next five decades
1. What
areas or groups have increased
2. What
industries have developed and/or moved into that particular region
3. What
cities in that particular region have grown the most, and how has that growth
contributed to water supply and quality:
4. Where
do the cities, industries, recreational facilities, and farms get their
water and who else does it affect?
5. Who
are the biggest users of the water supply?
6.How
are permits for water usage obtained?
7. What
is the water level in that region and in the dominant areas in that region
(has there been a trend in the past)?
8. Where
is water discharged in that region?
9. What
upstream or downstream issues exist?
10. Is
water supply and distribution affected by politics.How?
11. Are
there any cities with strong conservation and education efforts in that
region (if so, what are they)?
12. Overall, what needs to be
improved in that particular region (how)?
iv. Upon completing the research and presentations the students (as
a class) are to compare their results and come up with a class solution
to the problems in each region
