This document discusses land degradation and its forms and causes. It aims to teach students to identify activities that impact landscapes and the ways they can degrade land. Key forms of land degradation mentioned are erosion, salinity, and desertification. Major causes discussed include overgrazing, deforestation, crop growing, collection of firewood, and industrialization. Students are tasked with defining terms and creating a mind map showing the causes of land degradation with descriptions and examples for each.

9. As a class look at page 76 of the textbook.
• You will be creating your own mind map on inspiration maps
(or in your book)
• Your mind map will show the causes of land degradation
Activity

10. • The mind map must show the 5 main causes of land
degradation. One branch for each. Each cause must include:
o A simple definition/description of the cause
o A picture or an example of where this is happening
with a reference to the location
