Effects of soil erosion
Wind and water can scrap away the entire soil cover of an area creating bare ground. There is physical loss of the most fertile soil constituents.
The resultant poor soils are unable to effectively support plant growth and this results in low crop yields which may be followed by famine.
Severe loss of soil causes the degeneration of vegetation. Trees and grasses become poor and poorer and this makes the soils susceptible to further erosion.
Erosion by Runoff. Runoff has eroded small channels through this bare field.
Leads to creation of gullies and badlands which hinder transport.
Destruction of transport lines such as roads,
Persistent runoffs lead to the lowering of the water table. This comes about following death of plants and therefore reduction in infiltration.
Lowering of the water table leads to degeneration of vegetation and therefore emergence of drought. With reduction in the amount of vegetation cover, the humidity level in the atmosphere is lowered due to low evapo-transpiration leading to low absence of rainfall.
Eroded soil can lead to silting of lakes, canals and blocking of dams
Wind erosion produces dust particles which may move as dust storms over villages, towns and cities. Inhalation of too much dust can cause sickness. Other problems are to do with poor visibility.
