Origins & Early Life

Soil erosion is the denudation or wearing away of the upper layer of soil. It is a form of soil degradation. This natural process is caused by the dynamic activity of erosive agents, that is, water (e.g. landslide, flooding), ice (e.g. glaciers), snow (e.g. avalanches, snow gliding), air (e.g. wind), plants (e.g. tree uprooting), and animals (including humans).

Career & Major Achievements

In accordance with these agents, erosion is sometimes divided into water erosion, glacial erosion, snow erosion, wind (aeolian) erosion, zoogenic erosion and anthropogenic erosion such as tillage erosion. Soil erosion may be a slow process that continues relatively unnoticed, or it may occur at an alarming rate causing a serious loss of topsoil. The loss of soil from farmland may be reflected in reduced cropland area and production potential, lower surface water quality and damaged drainage networks.

Enduring Legacy & Impact

Soil erosion could also cause sinkholes and soil pipes that can further develop into rills and gullies. Human activities have increased by ca. 28 times the rate at which erosion is naturally occurring world-wide. Excessive (or accelerated) erosion causes both "on-site" and "off-site" problems.

Historical Fact-Check Quiz: Soil erosion

True or False: “The primary cause of soil erosion is always the natural cycle of water and wind.”

Answer (FALSE ❌): While natural forces are primary agents, human activities have accelerated the rate of soil erosion by an estimated 28 times the natural rate, making human impact a critical factor.
