Starter-think of 3 questions you would like to ask about this picture! What happened? When will it rain? Why me? Monday May 21 st  2007!
Lesson title: What is desertification? Aim:  to understand the causes and effects of Desertification To be aware that humans can help stop/slow down the process
Process via which land turns into desert. Desertification  is when a desert  gradually spreads  to the surrounding areas of semi-desert  = Desertification
Where is it happening? Parts of  Africa  have been the worst affected areas, especially a region called  The Sahel.
The Sahel stretches for   500km  from   Senegal and Mauritania   on the west coast to   Sudan and Ethiopia   on the east. The region covers   1/5 th  of Africa .  The Sahel Sahara Desert Task-  Draw a quick sketch of Africa in the space on your sheet- label and colour the Sahel and the Sahara desert to the North. Try to label some countries too! Parts of  Africa  have been the worst affected areas, especially a region called  The Sahel. Ethiopia Niger Sudan
What is the Sahel like? ,[object Object],[object Object],[object Object],[object Object]
[object Object],[object Object]
[object Object],DESERTIFICATION Increase in population Increase in cattle Deforestation for fire wood Grassland grazed more intensively Roots no longer hold soil together Roots may be eaten as well as grass Leaves no longer protect soil from weather Less vegetation means less protection from weather Loose top soil blown away by wind (Soil Erosion) = Loose top soil blown away by wind (Soil Erosion) = DESERTIFICATION
1) below average rainfall leading to extreme drought,. meaning the people have little rain to make the soil full of moisture so little can be grown in it Natural causes 2) Climate is naturally getting warmer which is increasing temperatures and decreasing rainfall in the Sahel region
Humans are generally considered to be the main cause of  Desertification, because of the way they abuse the land-  Over farming Overgrazing  Deforesting areas Increasing global Warming Human Reasons for Desertification in the Sahel.

[object Object],[object Object],[object Object],[object Object],Human Reasons for Desertification in the Sahel.
How does this lead to desert? Vegetation roots bind the soil. Vegetation dies. Soil is left exposed. Sun bakes the soil and it cracks. Wind will blow away the soil. Leaves are no longer present to intercept rain. The soil is washed away. The soil is degraded, over time losing fertility and structure.

  • 15. How does this lead to desert? Vegetation roots bind the soil. Vegetation dies. Soil is left exposed. Sun bakes the soil and it cracks. Wind will blow away the soil. Leaves are no longer present to intercept rain. The soil is washed away. The soil is degraded, over time losing fertility and structure.
