Soil erosion affects soil health and productivity by removing the highly fertile topsoil and exposing the remaining soil. It decreases agricultural productivity, degrades ecosystem functions and amplifies hydrogeological risk, such as landslides or floods
These impacts include compaction, loss of soil structure, nutrient degradation, and soil salinity. ... The effects of soil erosion go beyond the loss of fertile land. It has led to increased pollution and sedimentation in streams and rivers, clogging these waterways and causing declines in fish and other species.
