Explanation:
Contour bunding is a method of soil conservation that is not specifically limited to any particular ecological or geographical region. It is a technique used in various landscapes and terrains to prevent soil erosion and conserve water. Contour bunds, which are earthen or stone ridges constructed along the contour lines of the land, help in slowing down the flow of water and preventing soil erosion by retaining sediment and water on the slopes.
