Soil conservation means a way of keeping everything in place, literally as well as in a more abstract sense of maintaining the functions of the soil in sustaining plant growth. Soil conservation practices involve managing soil erosion and its counterpart process of sedimentation, reducing is negative impact and exploiting the new opportunities it creates. Young (1989) defined soil conservation as a combination of controlling erosion and maintaining soil fertility. In the past the focus has often been on trying to keep the soil at its place by plot-level activities only. Currently, the attention has switched to landscape level approaches where sedimentation is studied along with erosion, and the role of channels (footpaths, roads and streams) is included as well as the "filters" that restrict the overland flow of water and/or suspended sediment.
