water erosion
The breakdown of solid rock into smaller particles and its removal by water. As weathering, erosion is a natural geological process, but more rapid soil erosion results from poor land-use practices, leading to the loss of fertile topsoil and to the silting of dams, lakes, rivers and harbours. There are three classes of erosion by water. a) Splash erosion occurs when raindrops strike bare soil, causing it to splash, as mud, to flow into spaces in the soil and to turn the upper layer of soil into a structureless, compacted mass that dries with a hard, largely impermeable crust. b) Surface flow occurs when soil is removed with surface run-off during heavy rain. c) Channelized flow occurs when a flowing mixture of water and soil cuts a channel, which is then deepened by further scouring. A minor erosion channel is called a rill, a larger channel a gully. (Source: ALL)

agricultural machinery
Machines utilized for tillage, planting, cultivation and harvesting of crops. Despite its benefits in increasing yields, mechanisation has clearly had some adverse environmental effects: deep ploughing exposes more soil to wind and water erosion; crop residues can be removed as opposed to ploughing back into the soil; removal of residues can lead to a serious loss of organic content in the soil, which may increase the risk of soil erosion.

revegetation
Planting of new trees and, particularly, of native plants in disturbed sites where the vegetation cover has been destroyed, to stabilize the land surface from wind and water erosion and to reclame the land for other uses. Revegetation practices are employed in mined lands, roadsides, parks, wetlands, utility corridors, riparian areas, etc. (Source: REVEGa / CORBIT)

erosion control
Practices used during construction or other land disturbing activities to reduce or prevent soil erosion. Typical practices include planting of trees and quick growing grass on disturbed areas and other means to slow the movement of water across a disturbed site and trap the soil that does get transported by runoff.

environmental impact of agriculture
Agricultural activities have significant impacts on water quality, including increases in stream sedimentation from erosion, and increases in nutrients, pesticides, and salt concentrations in runoff. In certain regions, the misuse of pesticides has led to the development of pesticide-resistant strains of pests, destroyed natural predators, killed local wildlife, and contaminated human water supplies. Improper application of fertilizers has changed the types of vegetation and fish types inhabiting nearby waterways and rivers. (Source: RAU / WPR)

woodland clearance
The permanent clear-felling of an area of forest or woodland. On steep slopes this can lead to severe soil erosion, especially where heavy seasonal rains or the melting of snow at higher levels cause sudden heavy flows of water. In the humid tropics it may also lead to a release of carbon dioxide from the soil. (Source: ALL2)
