3 Desertification …Against the wind Sandstorm in Mauritania.

4 Desertification WHAT? Desertification = SPREAD, or GROWTH of the desert. WHERE? SAHEL region Directions: Copy what is in the box

5 Sahel – a narrow band of grassland along the southern edge of the Sahara Desert

6 Sahel Region in Southern Sudan

7 Clip - Desertification
How does desertification affect the environment? How does it affect the people?

8 Directions: Create a T-chart
Causes of Desertification Effects of Desertification

9 Causes of Desertification
OVERGRAZING – when land is exposed to continuous grazing for too long

10 Causes of Desertification
OVERGRAZING – when land is exposed to continuous grazing for too long Land needs time to recover

11 Directions: Create a T-chart
Causes of Desertification Effects of Desertification OVERGRAZING – when land is exposed to continuous grazing for too long - Land needs time to recover

12 Causes of Desertification
2. Deforestation – the cutting down and clearing away of forests. Trees and their roots hold the soil in place

13 Causes of Desertification
3. Drought – long periods of little or no rain. - Creates huge dust storms and harms crops Desert ghost-town in Mauritania.

14 Causes of Desertification
4. Poor Farming Techniques Overuse of land and groundwater Bad irrigation techniques Utilizing any available water source in Somalia.

15 SWBAT identify the effects of desertification.
1. Objective (READ) SWBAT identify the effects of desertification. 2. Question of the Day. (TURN OBJECTIVE INTO A QUESTION) 3. Warm-up (ANSWER) A. Sketch a picture that demonstrates desertification. B. Which cause of desertification is the most difficult to solve?

19 Effects of Desertification - Migration
Environmental Refugees – People are forced to move to other regions or countries - Migration causes conflict with people in their new homeland

21 5. What effect does drought have on African economies?
Directions: Answer the question in a complete sentence on your t-chart

22 Effects of Desertification
2. Decrease in arable land 3. Increases food prices and food shortages 4. Increases sandstorms that cause illnesses and economic loss Solar ovens are being given to African communities. They use the sunlight as an energy source. How do these help desertification?

23 Effects of Desertification
Directions: Answer the question underneath the picture in one of the boxes on your worksheet. Solar ovens are being given to African communities. They use the sunlight as an energy source. How do these help desertification?

24 ACTION PLANS ASSIGNMENT
You have been elected the new President of Mauritania, a country in West Africa. Create an action plan to solve four of the problems (causes or effects) related to desertification in the Sahel region of your country. Your plan must include the following An explanation of at least FIVE strategies or solutions for Desertification. Predict what will be the biggest hurdle to making your strategy work. Think about potential problems that could hurt your ability to fight desertification. (Who will get mad? What else do you need? What could make this hard?) Rank your strategies in terms of priority. #1 being the highest priority, #4 being the lowest priority. Explain your rankings for each strategy.

25 Action Plan You have been elected the new President of Mauritania, a country in West Africa. Directions: 1. Take a piece of official Mauritanian government paper and divide it into four sections. 2. Create an action plan to solve each of the four desertification causes OR EFFECTS in the Sahel region.

27 Drought - Provide drip irrigation so that the crops can be watered
In each square, include the following: 1. A picture of each step of your plan (4 total) 2. Explanation of how each strategy will work. Drought - Provide drip irrigation so that the crops can be watered

28 In each square, include the following:
DIRECTIONS: In each square, include the following: A picture of each step of your plan (4 total) Explanation of how each strategy will work. Answer the question below on the back of your paper. Conclusion question – Which part of your plan is the best? Explain why. Remember: When making solutions to big problems you can either: A. Fix the causes or, B. Make the effects better

29 Help: How would you fix each of these problems?
Drought? Deforestation? Overgrazing? Poor Farming Techniques Overuse of water and land Bad irrigation techniques

30 How would you make these effects better?
1. Environmental Refugees 2. Decrease in arable land 3. Increase in food prices 4. Increase sandstorms  illnesses, economic loss

31 Clip – China’s Plan 1. How is China fighting desertification?
2. Could this plan work in Africa too? Explain why or why not.

32 Exit Ticket Directions: Complete the exit ticket in the remaining box at the bottom of your paper. Answer the question of the day that you wrote in one of the other boxes. 2. Describe one economic, political, and social problem associated with desertification that you will be forced to deal with as President of Mauritania. - Label each problem, economic, political, or social.

33 Exit Ticket Directions: Complete the exit ticket in the remaining box at the bottom of your paper. Answer the question of the day that you wrote in your notebok like normal. Turn any desk that you see so that is facing, like we did on Monday.

34 Directions: - Go to - Click on the + sign in the upper left to zoom in on the placemarks that are circled below. - Title each placemark and write a short description about it in your notebook.

35 Water Video Analysis Create a list of the problems with water that you see on the video. PUT YOUR LIST ON THE BACK OF YOUR DESERTIFICATION PLANS
