Which one of the following changes may occur due to desertification?

Options

A. Decrease in atmospheric temperature
B. Increase in water holding capacity of soil.
C. Increased chances of floods.
D. Conversion of fertile land into a desert

Answer

**Step-by-Step Solution:**

1. **Understanding Desertification**: Desertification is the process where fertile land becomes increasingly arid and unproductive, often leading to the formation of deserts. This can occur due to various factors such as climate change, deforestation, and poor agricultural practices.

2. **Analyzing the Options**: The question provides several options regarding the changes that may occur due to desertification. We need to evaluate each option to determine which one accurately describes a consequence of desertification.

3. **Evaluating the First Option**: The first option states "decrease in atmospheric [something]." A decrease in atmospheric elements would not lead to desertification; instead, it would likely indicate a more stable or fertile environment.

4. **Evaluating the Second Option**: The second option mentions "an increase in the water holding capacity of soil." If the soil's water holding capacity increases, it means the land is becoming more fertile, which is the opposite of desertification.

5. **Evaluating the Third Option**: The third option refers to "an increase in the chances of floods." Increased flooding typically occurs in fertile areas with good vegetation cover. This does not correlate with desertification, where the land becomes dry and barren.

6. **Evaluating the Fourth Option**: The final option states "the conversion of fertile land into desert." This accurately describes desertification, as it highlights the transformation of productive land into barren desert.

7. **Conclusion**: Based on the analysis, the correct answer is the fourth option, which indicates that desertification leads to the conversion of fertile land into desert.

**Final Answer**: The conversion of fertile land into desert.
