Terracing prevents erosion, leaching and surface run-off, by trapping and slowing the water and soil that are being washed away.
That really all depends on where that farmer lives, what terrain he/she has to farm off, and the costs of contour plowing versus terracing. Some areas are not suitable for crop farming no matter what the options are, so the answer to that could be neither contour plowing nor terracing.
Terracing is carving small flat plots of land from hillsides used for farming. This is important so that farming is done on flat healthy plots of land, for good harvesting and growing.
