[amp_mcq option1=”increases the waterlogging area” option2=”decreases the waterlogging area” option3=”does not change the water logging area” option4=”none of the above” correct=”option2″]
The correct answer is: B. decreases the waterlogging area.
Lining of irrigation channels helps to reduce waterlogging by preventing water from seeping into the ground. This can be done by using a variety of materials, such as concrete, clay, or plastic. When water is prevented from seeping into the ground, it can be used more efficiently for irrigation, and the risk of waterlogging is reduced.
Waterlogging is a serious problem in many parts of the world. It can cause a number of problems, including crop damage, soil erosion, and the contamination of groundwater. Lining of irrigation channels is one of the most effective ways to prevent waterlogging.
Here are some additional details about each option:
- Option A: Lining of irrigation channels does not increase the waterlogging area. In fact, it can actually help to reduce waterlogging by preventing water from seeping into the ground.
- Option B: Lining of irrigation channels does decrease the waterlogging area. This is because it prevents water from seeping into the ground, which can be used more efficiently for irrigation.
- Option C: Lining of irrigation channels does not change the waterlogging area. This is not true, as lining of irrigation channels can actually help to reduce waterlogging.
- Option D: None of the above. This is not true, as lining of irrigation channels can actually help to reduce waterlogging.
