Land degradation is one of the severe environmental problems in China. In order to combat land degradation, a soil conservation program has been introduced since 2000 to reduce soil erosion by converting slope farmland into forest and pasture. This paper represents the first systematic attempt to investigate the impact of the soil conservation program on land degradation in the Loess Plateau. The results indicate that the soil conservation program to convert slope land into forest or pasture is an effective way to combat soil erosion. However, a subsidy that is higher than profit from slope land use activity before conversion is needed to encourage farmers to join the conservation program. Relevant policies to encourage and assist farmers to raise livestock in folds with crops produced from fields as well as fodder and forage grass from the converted slope land might contribute to combat soil erosion. Increase in off-farm job opportunities may encourage farmers' households to reduce farming practices on slope land. This implies that policies to encourage ruralurbanization might contribute to combat soil erosion.
