==Costs==
* Where stones are in short supply, there are increased costs associated with their acquisition and transport. * Labour for construction: 6-16 days per hectare. Annual maintenance: 3-18 days per hectare.* If bunds are formed in a terrace-like design, the labour required for construction is estimated at 150 to 350 person days/ha for terraces and cut off drains. The cost of these structures is approximately $60-460/ha.
