Which one of the following cannot be an effect of soil erosion ?

Options

A. desertification
B. desalinisation
C. flooding
D. famine

Answer

**Step-by-Step Solution:**

1. **Understand Soil Erosion**: Soil erosion is the process where the top layer of soil is removed, which can lead to various environmental impacts.

2. **Identify Effects of Soil Erosion**: Common effects of soil erosion include:
- Loss of fertile topsoil
- Decreased plant growth
- Desertification (conversion of land into desert)
- Deforestation (loss of trees and plants)
- Increased flooding due to loss of vegetation that holds soil in place
- Scarcity of food due to reduced agricultural productivity

3. **Analyze the Options**: The question asks which of the following cannot be an effect of soil erosion. The options provided are:
- Desertification
- De-salination
- Flooding
- Scarcity of food

4. **Evaluate Each Option**:
- **Desertification**: This can occur as a result of soil erosion, as the fertile land becomes barren.
- **De-salination**: This process involves removing salt from water and is not directly related to soil erosion.
- **Flooding**: Soil erosion can lead to increased flooding as the land loses its ability to absorb water.
- **Scarcity of food**: This can result from soil erosion due to decreased agricultural productivity.

5. **Conclusion**: The option that cannot be an effect of soil erosion is **De-salination**.

**Final Answer**: De-salination
