Correct option is C
The correct answer is: C) Low rainfall areas
Explanation:
Contour bunds are especially recommended for low rainfall areas to conserve soil moisture and reduce runoff.
Contour bunds are especially recommended for low rainfall areas to conserve soil moisture and reduce runoff.
These bunds are constructed along the contour lines of a slope, helping to slow down water flow, promote infiltration, and minimize soil erosion in dryland agriculture.
Information Key Points:
Contour bunds are earthen embankments built along the contour.
Used in dryland or semi-arid regions with rainfall below 750 mm/year.
Helps in moisture retention, erosion control, and improving crop yields.
Addition Information:
High rainfall areas: Graded bunding is preferred to allow safe drainage of excess water.
Medium rainfall areas: May use a combination of graded or contour bunds depending on soil and slope.
