What are the causes and consequences of desertification?
Overgrazing is the major cause of desertification worldwide. Other factors that cause desertification include urbanization, climate change, overuse of groundwater, deforestation, natural disasters, and tillage practices in agriculture that make soils more vulnerable to wind.
What are 3 causes of desertification?
Causes of desertification
- Population growth – the population in some desert areas is increasing.
- Removal of wood – in developing countries, people use wood for cooking.
- Overgrazing – an increasing population results in larger desert areas being farmed.
- Soil erosion – this is made worse by overgrazing and the removal of wood.
