Question

Given below are two statements:
Statement (I): Areas under rainfed agriculture are particularly affected by water erosion.
Statement (II): Areas under rainfed agriculture are particularly affected by wind erosion.
In light of the above statements, choose the most appropriate answer from the options given below.

• A. Both Statement (I) and Statement (II) are correct.
• B. Both Statement (I) and Statement (II) are incorrect.
• C. Statement (I) is correct but Statement (II) is incorrect.
• D. Statement (I) is incorrect but Statement (II) is correct.

Hint:

Rainfed fields alternate between wet and dry cycles.
Wet cycles lead to water erosion, while dry cycles lead to wind erosion, making them vulnerable to both.

Answer 1

The Correct Option is A

Step 1: Understanding the Concept:
Rainfed agriculture relies on natural precipitation rather than artificial irrigation.
These fields are highly vulnerable to environmental forces because they often lack continuous vegetative cover and stable soil structures.

Step 3: Detailed Explanation:
-

Statement I evaluation: During heavy rainfall events, rainfed agricultural soils face severe water impact. Without plant cover, soil particles loosen easily, causing sheet, rill, and gully water erosion. Hence, Statement I is correct.
-

Statement II evaluation: Rainfed areas often undergo dry seasons where the soil surface becomes dry and loose. High winds easily pick up and transport these unprotected soil particles, leading to significant wind erosion. Hence, Statement II is also correct.

Step 4: Final Answer:
Both Statement (I) and Statement (II) are correct.
