Question

The soil erosion problem in India is related to : 
(a) Excessive Mechanization of Agriculture 
(b) Winter rainfall (Mawath) 
(c) Excessive deforestation 
(d) Overgrazing 
Select the correct answer from codes given below :

Accepted Answer

The correct answer is Option 4: c and d. Here's why:

*   **Excessive deforestation (c):** Deforestation removes the tree cover that protects the soil from the impact of rainfall and wind. Tree roots bind the soil together, preventing it from being easily washed or blown away. When forests are cleared, the exposed soil becomes highly vulnerable to erosion. This is a significant contributor to soil erosion in India.

*   **Overgrazing (d):** Overgrazing occurs when livestock graze excessively in a particular area, removing the vegetation cover. This leaves the soil bare and unprotected, making it susceptible to erosion by wind and water. The hooves of animals also compact the soil, reducing its ability to absorb water and increasing runoff, which further exacerbates erosion.

Now, let's explain why the other options are incorrect:

*   **Excessive Mechanization of Agriculture (a):** While excessive mechanization *can* contribute to soil degradation in some cases (e.g., through soil compaction), it is not as direct or widespread a cause of soil erosion in India as deforestation and overgrazing. The impact of mechanization is more nuanced and depends on the specific practices used. It's not a primary driver of the widespread soil erosion problem.

*   **Winter rainfall (Mawath) (b):** Winter rainfall, while sometimes intense, is not the primary cause of soil erosion across India. While heavy rainfall events can contribute to erosion, the *lack* of protective vegetation cover (due to deforestation and overgrazing) is a more fundamental and widespread problem. Mawath is also geographically limited and doesn't affect all regions of India equally.

Therefore, the combination of excessive deforestation and overgrazing (Option 4) represents the most significant and direct causes of soil erosion in India, making it the correct answer.
