Conversion of fertile land into desert is called desertification. Which of the following is not a consequence of desertification?

Options

A. Decrease in the water holding capacity of soil.
B. Increased chances of floods.
C. Increase in the temperature of earth.
D. Decrease in the concentration of carbon dioxide in atmosphere.

Explanation

**Step-by-Step Solution:**

1. **Understand the Definition of Desertification**:
Desertification is the process where fertile land becomes desert due to various factors such as drought, deforestation, or inappropriate agriculture.

2. **Identify Consequences of Desertification**:
The consequences of desertification include:
- Increase in soil erosion
- Decrease in water holding capacity of the soil
- Loss of soil fertility
- Increase in temperature
- Increase in concentration of carbon dioxide in the atmosphere

3. **Analyze the Given Options**:
The question asks which of the following is NOT a consequence of desertification. We need to evaluate each option against the identified consequences.

4. **Evaluate Each Option**:
- **Increase in soil erosion**: This is a consequence of desertification.
- **Decrease in water holding capacity**: This is also a consequence of desertification.
- **Loss of soil fertility**: This is a consequence of desertification.
- **Decrease in concentration of carbon dioxide**: This is NOT a consequence of desertification; in fact, the concentration of carbon dioxide tends to increase due to the loss of trees which absorb CO2 during photosynthesis.

5. **Select the Correct Answer**:
Based on the evaluation, the correct option that is NOT a consequence of desertification is the one that states a decrease in the concentration of carbon dioxide.

**Final Answer**: The option that states a decrease in the concentration of carbon dioxide is NOT a consequence of desertification.
