Erosion is the wearing down of the surface of the earth due to the action of wind, water and gravity. It is a natural process and shapes the landscape around us. Use of land by man for agriculture, forestry, and transportation has accelerated these processes. Accelerated erosion has occurred in all the agricultural regions of Canada.
Erosion and runoff from agricultural land affects surface and groundwater quality as well as agricultural productivity. For an overview of these issues and their solutions, go to:
Impacts of Water Erosion
Risk of water erosion is greatest in humid areas of Canada but extreme storm events can produce serious soil losses even in dry regions. To read more on the processes of water erosion, effect on soil productivity and methods of erosion control, go to Water Erosion.
Impacts of Wind Erosion
Although risk of wind erosion is most severe in drier regions of Canada, sandy and organic soils in humid regions can also be prone to wind erosion during periods of very dry weather.
