ABSTRACT
For populous countries where arable land is limited, terracing is a useful conservation measure applied on steep slopes for increasing crop production and minimizing soil erosion. Terracing is not new. In many parts of the world, this technique has been used for more than a thousand years. Today, however, there are two challenges. The first challenge is to design terracing systems that are compatible with modem farming practices such as machine cultivation, transportation, spraying, drainage, and irrigation. The second challenge is to design terrace systems that are scientifically sound yet simple enough so that people at the local level can understand and construct them with only a little training.
