Contour bunding is a soil conservation practice applied on gently sloping land. It involves constructing narrow-based bunds (embankments) along the contour lines. The purpose is to intercept and slow down water runoff, reduce soil erosion, and promote infiltration of water into the soil. This method is particularly effective in semi-arid areas for moisture conservation. The conditions described in options A, B, and C do not match the primary application of contour bunding. Option A describes desert margins prone to wind erosion. Option B describes low flat plains prone to flooding, where different flood control measures are used. Option C describes scrublands and weed growth, not directly addressed by contour bunding.
