Semi-circular bunds

Semi-circular bunds are used to rehabilitate degraded, denuded and hardened land for crop growing, grazing or forestry. The technology involves building low embankments with compacted earth or stones in the form of a semi-circle with the opening perpendicular to the flow of water and arranged in staggered rows.

They are constructed on gently to moderately sloping pediments and plateau areas in order to rehabilitate areas that are degraded, denuded and/or affected by soil crusting. The bunds reduce the loss of water and the fertile layers of the soil.
