Study Notes
Desertification Causes and Effects
- Overgrazing is a major cause of desertification, leading to the degradation of land and soil quality.
- When overgrazing occurs, the soil is depleted of its vegetation cover, causing it to become vulnerable to erosion and loss of nutrients.
Soil Erosion and Desertification
- Soil erosion contributes to desertification by removing the topsoil layer, which is rich in nutrients, and reducing the soil's ability to support plant growth.
Drought and Desertification
- Increased drought and loss of topsoil can lead to reduced crop yields, decreased agricultural productivity, and increased poverty.
Prevention of Desertification
- Tree roots play a crucial role in preventing desertification by holding soil in place, maintaining soil quality, and reducing soil erosion.
