2021-04-13 · 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. And degraded lands are also often less able to hold onto water, which can worsen flooding.

Soil erosion is one of the most serious environmental and public health problems facing human society. Humans obtain more than 99.7% of their food (calories) from the land and less than 0.3% from the oceans and other aquatic ecosystems. Each year about 10 million ha of cropland are lost due to soil

Soil erosion

The term soil erosion covers a wide range of physical and chemical actions, such as removal of soluble matters, chemical changes, disintegration by frost or by rapid changes of temperature, attrition by dust charged wind, scouring by silt laden currents, alternate impact and succession by storm waves, landslides and so on – Fox (1950). Soil Erosion: Definition And The Truth Behind Its Main Causes As mentioned above, water, wind, and field works such as tillage are the primary agents of soil erosion. The term soil erosion covers a wide range of physical and chemical actions, such as the removal of soluble matters, chemical changes, disintegration by frost or by rapid changes of temperature, attrition by dust charged wind… Resistance to erosion The ability of soils to resist water and wind erosion depends on their texture and topographic characteristics. Clay-rich soils resist erosion well because of strong cohesive forces between particles and the gluelike characteristics of humus. Due to soil erosion, the soil becomes less fertile.

An Assessment of the global impact of 21st century land use change on soil erosionHuman activity and related land use change are the primary cause of accelerated soil erosion, which has substantial implications for nutrient and carbon cycling, land productivity and in turn, worldwide socio-economic conditions. Here we present an unprecedentedly high resolution (250 × 250 m) global potential

Surface Runoff and Rainfall Erosion. Surface runoff from rainfall and rainfall itself can result in large … Soil erosion is the widespread concern as it leads to loss of the top fertile layer of the soil. Soil erosion is termed as the detachment, transportation and deposition of soil particles by the Soil erosion is the washing away of the top layer of the soil by water, plants, animals, air, snow, or humans. It involves the displacement and deposition of the soil in other areas. The top layer is the most fertile and nutrient filled layer of the soils.

Erosion removes the best, most fertile part of the soil, the topsoil where most of the plant nutrients and soil carbon are found. Soil Erosion is the process that erodes, breaks or gradually diminishes things down. The process of erosion usually takes place on the surface of soil, rock, or dissolved material from one location on the Earth’s crust and with the help of the wind or water flow, it gets to settle down at another location.
