Where is the water in Southwest Asia?

Water in Southwest Asia 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? Water in Southwest Asia

What can we conclude from this map?

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.

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

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

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

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

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. Keban Dam on the Euphrates River in Turkey

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

How have people in Southwest Asia modified the environment to provide valuable water? 1) Damming Rivers 2) Pivot Irrigation 3) 4) Q of Day

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

Pivot Irrigation systems at work!

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.

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

Desalination Plants are water treatment plants that remove salt from ocean water. - =

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?

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

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

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

Drip Irrigation is the use of small pipes to slowly drip water just above the ground. Keeps water from Evaporating in the arid climate http://www.omarproperties.co.uk/irrigation.html

Drip Irrigation allows for date palm trees to grow on a farm in the deserts of Southwest Asia

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 http://www.ruf.rice.edu/~parish/geraldlink1.html

Water in Southwest Asia 1) Damming Rivers – Provides water for drinking, irrigation, and hydroelectricity. How have people modified the environment? Drip Irrigation - Desalination Plants - Pivot Irrigation -

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

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

Google Earth Tours Cut-away boxes Saving: - 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

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 - http://www.net-travel.org/kibbutz/sites_list.htm
