[34] [35] 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 [36] [37] [38] A signature spatial pattern of soil erosion shown in many water erosion handbooks and pamphlets, the eroded ...
Sand and water on the side of the road, causing erosion on the environment Plastic bags dumped by the road side in Katete in mbarara district in western Uganda. The erosion caused by rains, rivers and winds as well as over-use of soils for agriculture and low use of manures have resulted in turning the soils infertile, as for example, in the plains of the Nile and the Orange River.
Local girls from Babile (Ethiopia) fill plastic water containers at the area's main water source.. Sub-Saharan Africa has the largest number of water-stressed countries of any other place on the planet and of an estimated 800 million people who live in Africa, 300 million live in a water stressed environment.

Potato field with soil erosion. In addition to the usual types of land degradation that have been known for centuries (water, wind and mechanical erosion, physical, chemical and biological degradation), four other types have emerged in the last 50 years: [11] pollution, often chemical, due to agricultural, industrial, mining or commercial ...
Erosion and changes in the form of river banks may be measured by inserting metal rods into the bank and marking the position of the bank surface along the rods at different times. [23] Thermal erosion is the result of melting and weakening permafrost due to moving water. [24] It can occur both along rivers and at the coast.
A decrease in freshwater entering the river due to irrigation and, thus, a decrease in sediment load has increased coastal erosion of the delta. Hydraulic structures and sea level rise also play a role in the loss of the delta. [22] The Volga Delta is formed when the Volga River enters into the Caspian Sea in Russia. It has gained land with the ...
The Arctic Ocean's ability to absorb carbon dioxide from the atmosphere appears to be waning due to melting permafrost and worsening coastal erosion. Arctic ocean may absorb less CO2 than ...
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.
