The principal advantage of terrace cultivation is that it can protect the terraced's area soil from rapid erosion. Erosion happens when moving water strips away soil from the area over which it is flowing. Terracing by reducing the length of the slope the water has to run over i.e. by creating a level terrace on an otherwise sloped face, slows the flow of water. This protects the soil in the area from being carried away in a deluge.  Level terraces, found in parts of Bali and China, can not only reduce the rate of soil erosion but can also trap and hold rainwater. This allows the cultivation of water - intensive crops such as rice in these areas. Water collected in the terraces can be absorbed into the soil and sustain crops.  Terracing requires huge labor to construct and maintain, and when not properly maintained, the effects can be catastrophic. Unmaintained terraces can lead to mudslides, the creation of deep gulleys and increased soil erosion, particularly in sandy soils or an
