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

3 What can we conclude from this map?

4 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. Big Dry Problem

5 Let’s add to our concept map. Include both written and visual information. Water in Southwest Asia Why is there a limited amount of water? How have people modified the environment? Desert and Semi-arid Climate. Few major freshwater sources

6 How have people in Southwest Asia modified the environment to provide valuable water? 1) Damming Rivers 2) 3) 4)

7 The Hemren Dam on the Tigris River provides water for drinking, irrigation and hydroelectricity. Note the arid climate and lack of vegetation

8 Let’s add to our concept map. Include both written and visual information. Water in Southwest Asia Why is there a limited amount of water? How have people modified the environment? 1) Damming Rivers – Provides water for drinking, irrigation, and hydroelectricity. Desert and Semi-arid Climate.

9 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 Read the section titled “Dams and Irrigation Systems.” –Add the REASON FOR THE CONTROVERSY to your chart. Keban Dam on the Euphrates River in Turkey

10 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 3) 4)

12 Pivot Irrigation is an above ground system of watering crops that forms circles of arable land. Circles of green irrigated vegetation in Saudi Arabia, April 1997 Arable Land Desert Land

13 Pivot Irrigation systems at work!

14 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)

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 it’s water problems. Question – How does a desalination plant work?

18 Water comes in on this side Water comes out on this side Desalination Plant in Tampa, FL

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

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

22 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

24 Complete your concept map. Add a picture for Drip Irrigation Water in Southwest Asia Why is there a limited amount of water? How have people modified the environment? 1) Damming Rivers – Provides water for drinking, irrigation, and hydroelectricity. Desalination Plants - Pivot Irrigation - Drip Irrigation - Desert and Semi-arid Climate.

25 Complete your concept map. Water in Southwest Asia Why is there a limited amount of water? How have people modified the environment? How have people adapted to the environment? 1) Damming Rivers – Provides water for drinking, irrigation, and hydroelectricity. Drip Irrigation - Pivot Irrigation - Desalination Plants - Desert and Semi-arid Climate.

26 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.

27 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, I’d 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) 5. Kibbutz - travel.org/kibbutz/sites_list.htmhttp://www.net- travel.org/kibbutz/sites_list.htm
