Question

The major activities of the command area development are:

(A) Modernisation and efficient operation of irrigation systems as well as development of main drainage systems.
(B) Construction of field channels.
(C) Land shaping and levelling job are not required.
(D) Construction of field drains.

Choose the correct answer from the options given below:

• A. (A), (B) and (C) only.
• B. (B), (C) and (D) only.
• C. (A), (B) and (D) only.
• D. (A), (C) and (D) only.

Hint:

Command Area Development covers the entire chain from the main canal down to the farmer's field, ask whether land levelling would really be skipped in that chain.

Answer 1

The Correct Option is C

Step 1: The Command Area Development (CAD) programme is meant to close the gap between the irrigation potential created by a project and what actually reaches the field, so its activities cover the full path from the main system down to the farmer's field.

Step 2: Statement (A) is a core CAD activity, modernising and running the irrigation system efficiently and developing main drainage so excess water can be removed. This is correct.

Step 3: Statement (B), construction of field channels that carry water from the outlet to individual fields, is one of the most basic on-farm development works under CAD. This is correct.

Step 4: Statement (D), construction of field drains to take away excess water and control waterlogging and salinity in the command area, is also a standard CAD activity. This is correct.

Step 5: Statement (C) claims land shaping and levelling are not required. This is false. Land shaping and levelling are in fact essential CAD activities because they let water move and spread evenly over the field, without them irrigation efficiency drops sharply. So (C) must be excluded.

Step 6: With (A), (B) and (D) true and (C) false, the correct combination is (A), (B) and (D) only.
