Warm - Up

Physical Water Scarcity

Physical water scarcity is where there is physically not enough water to meet all demands, including that needed for ecosystems to function effectively.

Economic Water ScarcityEconomic water scarcity is a type of water

scarcity caused by a lack of money being spent/money available to spend on obtaining water. The water may be there, but the money or tools to access it is not. It may also have to do with insufficient infrastructure to keep up with the demand for water resulting in people often having to fetch water from rivers or lakes for domestic and agricultural uses.

Causes of Water Scarcity…

What could some causes of water scarcity be?• Population growth• Food production• Climatic change and variability• Land use• Water quality• Water demand• Poverty and economic policy• Legislation and water resource management• International water disputes

Think About It…

We have the luxury of turning on the faucet and water comes out. Does everyone?

This is what we call water availability…

Water Availability:

• Water Availability:

The access to, or availability of water for use

per person in a particular area

Tribal Challenge Water Relay• 6 Tribes – Each Tribe has 1 Dixie cup and 1

beaker. (except Tribe 5 – they have 2 beakers and 2 Dixie cups)

• The goal of each tribe is to get as much water in their beaker as possible in 5 minutes…however, your water sources are not equally available

Tribal Challenge Water Amounts

• Tribe 1 = • Tribe 2 = • Tribe 3 = • Tribe 4 = • Tribe 5 = • Tribe 6 = • It is clear that the tribes did not have equal access to

water, but now how will you figure out how to divide the water up amongst your tribe members?

Tribal Challenge Water Amounts

• Tribe 1 = • Tribe 2 = • Tribe 3 = • Tribe 4 = • Tribe 5 = • Tribe 6 = • How is this representative of different continents of the

world and their water availability? – PREDICT THE CONTINENT COMPARISON WITH YOUR TABLE PARNTER NOW…

Tribal Challenge Water Continent Comparisons

• Tribe 1 = North America • Tribe 2 = Europe• Tribe 3 = Asia• Tribe 4 = South America• Tribe 5 = Australia• Tribe 6 = Africa

Tribal Challenge Quick Write & Discussion

• What are some other factors that need to be considered that may be affecting the level of water availability?

• What aspects of your life would suffer because your time would be consumed with getting water?

Water Availability in the U.S.

•What water sources do we have available to us in the

United States?

The Great Lakes• The Great Lakes are the largest fresh

water system on Earth. They contain 84% of North America’s surface fresh water and 21% of the world’s surface fresh water supply. Only the polar ice caps contain more fresh water!

OGALLALA AQUIFER – UNDER U.S.

• Huge source of freshwater for drinking & irrigation in the U.S.

• Depleting at alarming rate… – “The average

annual depletion rate between 2000 and 2007 was more than twice that during the previous fifty years!”

Water Availability in the U.S.• What other water

resources do we have available in the U.S.?

• Would you consider the U.S. a good place to live in terms of water availability…Why?

Water SustainabilitySo, should we/do we have enough water for everybody???

That is what water sustainability means…

Water Sustainability:Water Sustainability• The use of water that

ensures that water will be a protected and available resource for future generations.

Will there be enough to sustain our growing population?

In Fact…• Right now, 1.1 billion people do

not have access to improved sources of drinking water, they must carry water for several miles, and even then it may not be safe.

Carrying Water in Kenya…Close your eyes and imagine you live in the village of

Kapsasian, Kenya…story time

Carrying Water in Kenya…• Calculate the reality of carrying water in Kenya…

• These are real-life problems faced by billions of people around the world.

• You and your family must live off of less than 10 gallons of water a day. How would life be different?

But You Do Have Access to Water…How Much Do You Use?

• Discussion Questions:– Were you surprised by your daily personal water

usage? How did your initial estimate compare to your actual usage?

– How much of your total water was actually used and how much was wasted down the drain?

– Do you think you actually use more water than was calculated in your audit? Why or why not?
