“Land Degradation: Creation and Destruction,” by Douglas L. Johnson and Laurence A. Lewis, states that the main naturally induced causes of land degradation are wind and water erosion. Wind erosion occurs in areas with little or no vegetation and sandy soil, so strong winds carrying soil particles deteriorate the land. Land Use/Land cover change and soil erosion in Ethiopia. Land use/land cover changes and land degradation are highly interrelated [67,68] because usually the changes are associated with deforestation, biodiversity loss and land degradation [69]. Land cover is one of the factors that determine the rate of soil loss due to erosion. 2020-04-15 · Land Use Land Cover Change (LUCC) was reported to be one of the dominant factors affecting soil erosion in a landscape [ 16 ]. LUCC, combined with several atmospheric and topographical conditions, has an accelerating impact on soil and land degradation [ 17 ], including acidification, alkalization, soil erosion and nutrient leaching.

2020-11-17 · Grazing land cannot remain healthy and erosion-resistant if cattle are allowed to graze year-round. For best results, close off a paddock for the entire wet season to allow grasses to reestablish themselves. This may not be effective if the other paddocks cannot support the spelled cattle.

In earth science, erosion is the action of surface processes that removes soil, rock, or dissolved material from one location on the Earth's crust, and then transports it to another location. Erosion is distinct from weathering which involves no movement. Removal of rock or soil as clastic sediment is referred to as physical or mechanical erosion; this contrasts with chemical erosion, where soil or rock material is removed from an area by dissolution.

Soil erosion is the detachment and movement of soil particles from the point of origination through the action of water or wind. Thus, minimizing the impact of water or wind forces is the main objective for erosion control. Water erosion is the most pertinent erosion problem in Iowa. Soil erosion by water occurs when bare-sloped soil surface is exposed to rainfall, and the rainfall intensity exceeds the rate of soil intake, or infiltration rate, leading to soil-surface runoff.
