Introduction Conservation tillage systems using sweep plows or field cultivators leave a high percentage of crop residues on the soil surface, which protects the soil from wind and water erosion (Johnson, 1950; Jones and Johnson, 1982; Allen and Fenster, 1986; Johnson et al., 1974). These systems have been successful in semiarid areas because meager rainfall after plowing does not allow weeds t...

land degradation due to soil erosion has been well pointed out as one of the most serious ecological and economic problems that some such south asian countries including iran are faced with. although high investment has been made, particularly in introduction of soil conservational mechanical practices, the level of acceptance of these practices has been low and while a high rate of erosion con...

As one of the key tools for regulating human-ecosystem relations, environmental conservation policies can promote ecological rehabilitation across a variety of spatiotemporal scales. However, quantifying the ecological effects of such policies at the regional level is difficult. A case study was conducted at the regional level in the ecologically vulnerable region of the Loess Plateau, China, t...
