[35] [36] There is growing evidence that tillage erosion is a major soil erosion process in agricultural lands, surpassing water and wind erosion in many fields all around the world, especially on sloping and hilly lands [37] [38] [39] A signature spatial pattern of soil erosion shown in many water erosion handbooks and pamphlets, the eroded ...
Overgrazing typically increases soil erosion. [7]With continued overutilization of land for grazing, there is an increase in degradation. This leads to poor soil conditions that only xeric and early successional species can tolerate. [8]
Soil erosion in a wheat field near Pullman, US. High population density is not always related to land degradation. Rather, it is the practices of the human population that can cause a landscape to become degraded. Severe land degradation affects a significant portion of the Earth's arable lands, decreasing the wealth and economic development of ...

Desertification is a gradual process of increased soil aridity.Desertification has been defined in the text of the United Nations Convention to Combat Desertification (UNCCD) as "land degradation in arid, semi-arid and dry sub-humid regions resulting from various factors, including climatic variations and human activities."
If the erosion rate exceeds soil formation, erosion destroys the soil. [76] Lower rates of erosion can prevent the formation of soil features that take time to develop. Inceptisols develop on eroded landscapes that, if stable, would have supported the formation of more developed Alfisols. [77] While erosion of soils is a natural process, human ...
Soil erosion is the main factor for soil degradation and is due to several mechanisms: water erosion, wind erosion, chemical degradation and physical degradation. Erosion can be influenced by human activity. For example, roads which increase impermeable surfaces lead to streaming and ground loss.
These limitations to the growth of plants can have a very negative effect on plant health, leading to a decrease in the overall plant population. These effects occur regardless of the biome. A study in the Netherlands examined the correlation between soil pH and soil biodiversity in soils with pH below 5. [8]
