Grazing. ... If too many animals graze the same land area, the animals' hooves pull plants out by their roots. A land is overgrazed if too many animals are living there. Grazing animals can cause erosion if they are allowed to overgraze and remove too much or all of the vegetation in a pasture.
Agriculture. Agriculture is the main way humans cause soil erosion. When vegetation is planted in the ground, the topsoil is shifted, which causes erosion. The loose topsoil is then transported by wind to nearby streams and waterways and become sediment or runoff, lowering the overall quality of the water.
Explanation:
Soil erosion occurs naturally by wind or harsh climatic conditions but human activities include overgrazing, overcropping and deforestation. Overgrazing occurs when farmers stock too many animals such as sheep, cattle or goats on their land
What is soil erosion and soil degradation? Although soil erosion is a natural process, human activities over the past decades have greatly accelerated it. In fact, according to the UNESCO, land degradation is undermining the well-being of two-fifths of humanity, driving species extinct and intensifying climate change. According to a senior UN official, all of the world’s topsoil could be gone within 60 years.
Soil Erosion Simple Definition
Soil erosion is a gradual process of movement and transport of the upper layer of soil (topsoil) by different agents – particularly water, wind, and mass movement – causing its deterioration in the long term.
In other words, soil erosion is the removal of the most fertile top layer of soil through water, wind and tillage.
What Is Soil Erosion? A Soil Erosion Scientific Definition
According to a Pereira and Muñoz-Rojas (2017) synthesis, soil erosion is one of the major causes, evidence of, and key variables used to assess and understand land degradation. Soil erosion is a consequence of unsustainable land use and other disturbances, such as fire, mining, or intensive agricultural uses. The loss of soil may have serious impacts on the quantity and quality of soil ecosystem services, with serious economic, social, and political implications.

Different Soil Erosion Causes
Soil erosion is a complex process that depends on soil properties, ground slope, vegetation, and rainfall amount and intensity. According to Montgomery, modifications in land use are one of the most impactful ways of accelerating soil erosion. These changes then have a cascade effect as the loss of fertile topsoil cover sends millions of tons of sediments into lakes and reservoirs, changing ecosystems and impacting agricultural production and water quality. This has been the case with the Bo River in Vietnam.
According to Al-Kaisi from Iowa State University, there are 5 main types of natural soil erosion:
1) Sheet erosion by water;
2) Wind erosion;
3) Rill erosion – happens with heavy rains and usually creates smalls rills over hillsides;
4) Gully erosion – when water runoff removes soil along drainage lines
5) Ephemeral erosion that occurs in natural depressions.
