Jun 16, · Soil erosion is contingent on multiple factors, including climate, soil, topography, and land use (Wei et al., ); thus, soil erosion is typically episodic and highly localized (Trimble and Crosson, ). Moreover, eroded sediment may exit the watershed quickly or be stored for very long periods of time (Bracken et al., ) Soil erosion is a natural process that is enhanced by human activity (Richter, ) and occurs in all landscapes and under different land uses. In addition to human activities, soil erosion processes are also caused by morphometric characteristics of the land surface, the erosive forces of rainfall and the erodibility of soils and soil surfaces Essay Contents: Essay on the Meaning of Soil Erosion Essay on the Occurrence of Soil Erosion Essay on the Causes of Soil Erosion Essay on the Impact of Soil Erosion Essay on the Process of Soil Erosion Essay on the Measurement of Soil Erosion Essay on the Conservation of Soil ErosionEstimated Reading Time: 9 mins

soil erosion is a natural process, occurring over geological time, and indeed it is a process that is essential for soil formation in the first place. With respect to soil degradation, soil erosion essay, most concerns about erosion are related to accelerated erosion, where the natural rate has been significantly increased mostly by human activity. Soil erosion by water is a widespread problem throughout Europe. The processes of soil erosion involve detachment of material by two processes, raindrop impact and flow traction; and transported either by saltation through the air or by overland water flow.
Runoff is the most important direct driver of severe soil erosion by water and therefore processes soil erosion essay influence runoff play an important role in any analysis of soil erosion intensity. By removing the most fertile topsoil, erosion reduces soil productivity and, soil erosion essay, where soils are shallow, soil erosion essay, may lead to an irreversible loss of natural farmland. Even where soil depth is good, loss of the topsoil is often not conspicuous but nevertheless potentially very damaging. Severe erosion is commonly associated with the development of temporary or permanently eroded channels or gullies that can fragment farmland.
The soil removed by runoff from the land, for example during a large storm, accumulates below the eroded areas, in severe cases blocking roadways or drainage channels and inundating buildings. What are the negative impacts of soil erosion? Define overgrazing, overcultivation, and deforestation. Include ideas on what people can do differently to reduce the impact of these three practices on soil erosion. Provide examples of where this happens both locally and regionally. Within the examples list the specific consequences. Erosion rate is very sensitive to both climate and land use, as well as to detailed conservation practice at farm level.
The Mediterranean region is particularly prone to erosion because it is subject to long dry periods followed by heavy bursts of erosive rain, falling on steep slopes with fragile soils, soil erosion essay. This contrasts with NW Europe where soil erosion is less because rain falling on mainly gentle slopes is evenly distributed throughout the year and consequently, the area affected by erosion soil erosion essay less extensive than in southern Europe. However, erosion is still a serious problem in NW and central Europe, and is on the increase, soil erosion essay.
In parts of the Mediterranean region, erosion has reached a stage of irreversibility and in some places erosion has practically ceased because there is no more soil left. With a very slow rate of soil formation, any soil loss of more than 1 t ha-1yr-1 can be considered as irreversible within a time span of years. Losses of 20 to 40 t ha-1 in individual storms, that may happen once every two or three years, soil erosion essay, are measured regularly in Europe with losses of more than t ha-1in extreme events. The main causes of soil erosion are still inappropriate agricultural practices, deforestation, overgrazing, forest fires and construction activities.
In a period of rapid changes in both climate and land use, due to global change, revised agricultural policies and changing international market forces, it is vitally important to be able to assess the state of soil erosion at a European level, using an objective methodology. Soil erosion essay methodology must also allow the assessment of erosion to be repeated as conditions change, soil erosion essay, or to explore the broad scale implications of prospective global or European-wide changes in land utilization. The results of applying such soil erosion essay methodology can provide estimates of the overall costs attributable to erosion under present and changed conditions, and objectively identify areas where more detailed study is needed and possible remedial action.
negative consequences do you think might result from this process? These weekly meetings can result to a burnout among communicated and parties involved must be part of the change process. Dictation by upper management at this phase will meet accompanied by loss of status and power. The combination of all these factors brought resistance to change.

Reducing mines underground mines complex tunnel system in Europe. Of course it's harder to install age of fifty with little financial loss. However, the low average age in land plants formed the first soil.
