How Does Soil Erosion Affect Us?

Erosion is a process due to which the soil, rock debris, etc. of the earth’s surface loosens and is moved away which is described as the “wearing away” of the land. When there is rainfall on soft ground, streams and rivers can be seen carrying thick mud with them. The wind carries sand and dust from one place to another. Flowing water of rivers can take away the clay from its banks. Currents of river water are very powerful, they can grind stones, reduce rocks to sand and sand to finer sand. They carry these with them to give them away to the sea.

Rivers and streams give rise to beautiful waterfalls, valleys, and can produce wonders like the Grand Canyon of Arizona. But erosion is of great concern to human beings because it also removes the fertile topsoil, changes the course of river waters, and can cause damage to farms, forests and also to man-made structures.

In ancient times, much erosion was done by glaciers.

Regions having low rainfall and dry seasons suffer because their soil become dry and dusty which is easily blown away by the wind if the land has no vegetation. One of the worst cases of this kind of wind erosion took place in mid-western states of the U.S.A. in 1930s. It left the area devastated which is called the “Dust Bowl”.

Soil scientists and agricultural experts study these problems and their studies tell us that by cutting down forests, especially on the higher slopes or mountains, can result in soil erosion which can damage the lowland or farmland seriously. They also guide farmers to help reduce soil erosion and improve soil conservation.
