Living World Flashcards
What is a case study based on Living World?
The Sahel Desert Fringe, Africa
What are the characteristics of the Sahel Desert Fringe?
More predictable rainfall patterns
More vegetation
Known as semi-deserts and semi arid areas
What are the human causes of desertification?
Population Increase= high birth rates and migration
Over-cultivation= over cropping, land exhausted and soul erodes losing nutrients
Over-grazing=vegetation is eaten entirely, soil exposed,
How can we tackle desertification?
Better land management= ,flat roofs with surrounding lip to collect water and tree planing schemes
Afforestation= soil not exposed to sun, reduced soil erosion,
Appropriate Technology= people use wood for fuel, which leads to desertification therefore we should use toyola stoves because they retain heat for longer (they are made from clay)
