Where is the water

1
Where is the water in Southwest Asia?
2
As we learn about Southwest Asia and how they use
their water, students will complete a concept web.
Why is there a limited amount of water?

3
What can we conclude from this map?
4
Big Dry Problem

• There are few major fresh water sources, like the
  TIGRIS and EUPHRATES Rivers.
• Southwest Asia must find other ways to collect
  water for daily uses and survival.

5
Lets add to our concept map. Include both
written and visual information.

Water is so valuable that countries will fight
for its control and use!

• There is controversy over Turkey building a
  series of dams on the Euphrates River.
• TASK ? Explain the controversy.
• Turn to p. 495. Read the section titled Dams
  and Irrigation Systems.
• Add the REASON FOR THE CONTROVERSY to your chart.

Dam Controversy

• SYRIA and IRAQ think it will take away precious
  water supplies that THEY need for drinking,
  irrigation, and hydroelectric power plants.

11
How have people in Southwest Asia modified the
environment to provide valuable water?

• 1) Damming Rivers
• 2) Pivot Irrigation

• 4)

Q of Day
12
Pivot Irrigation is an above ground system of
watering crops that forms circles of arable land.

Pivot Irrigation

• Task ? Pivot Irrigation Explanation/Sketch
• Turn to someone near you.
• Explain Pivot Irrigation.
• Sketch an example of Pivot Irrigation on your
  concept map.

15
How have people in Southwest Asia modified the
environment to provide valuable water?

• 1) Damming Rivers
• 2) Pivot Irrigation
• 3) Desalination Plants
• 4)

Q of Day
16
Desalination Plants are water treatment plants
that remove salt from ocean water.

17
Desalination Plants - Clip

• Intro This clip is about a small community in
  California that built a desalination plant to
  address its water problems.
• Question How does a desalination plant work?

19
Problems with Desalination Plants

• 1. Water can be too salty for irrigating crops
• 2. Expensive to operate (costs a lot of money)
• 3. Cannot provide enough fresh water for all the
  needs of citizens

20
How have people in Southwest Asia modified the
environment to provide valuable water?

• 1) Damming Rivers
• 2) Pivot Irrigation
• 3) Desalination Plants
• 4) Drip Irrigation

Q of Day
21
Drip Irrigation is the use of small pipes to
slowly drip water just above the ground.
Keeps water from Evaporating in the arid climate

Drip Irrigation allows for date palm trees to
grow on a farm in the deserts of Southwest Asia
23
A Kibbutz in Israel is an agricultural community
relying on irrigation to produce crops for the
community and country.
Notice the climate surrounding the irrigated land

How have people in Southwest Asia adapted to the
arid climate?

• Agriculture Grow crops and raise animals that
  require less water.
• Recycle Treat waste water for use in
  agriculture.

Google Earth Tours

• Create a Google Earth tour that locates examples
  of the ways people in SW Asia have modified the
  environment to provide water.
• Include 5 cut-away boxes
• 1. Drip Irrigation
• 2. Pivot Irrigation
• 3. Damming Rivers
• 4. Desalination Plants
• 5. Kibbutz

28
Google Earth Tours

• Cut-away boxes
• - Each cut-away box must point to the location of
  a corresponding example. You may have to search.
  You this powerpoint or reputable online sources
  to locate examples.
• - Explanation Explain how each example provides
  water.
• Saving
• Save it on the wiki or in your student folder
• If saving on the wiki, Id save it in your
  student folder 1st

29
Google Earth Tours

• Resources for cut-away boxes
• 1. Drip Irrigation
• 2. Pivot Irrigation (look in Saudi Arabia)
• 3. Damming Rivers (type Ataturk Dam in the search
  window of Google Earth)
• 4. Desalination Plants (see next slide)
