SIGNIFICANCE OF SOIL EROSION
2.2 LITERATURE REVIEW- SIGNIFICANCE OF SOIL EROSION
SIGNIFICANCE OF SOIL EROSION;
Because of the negative consequences it has on people, soil erosion is a global phenomenon. As a result, there is a ton of literature on these topics. The ones that apply to this study will be reviewed and debated.
EFFECTS OF SOIL EROSION/ CAUSES- SIGNIFICANCE OF SOIL EROSION
With numerous social and economic repercussions, soil erosion has been recognized as a severe environmental issue. Its repercussions are multi-faceted, and soil erosion is a terrible kind of environmental deterioration. According to Michael Pidiwirmy (2010), there are a variety of reasons why historical erosion affects a soil’s ability to erode. For example, many exposed subsurface soils on eroded sites tend to be more erodible than the original soil due to their inferior structure and lower organic content. Lower crop yields and typically worse crop cover as a result of the subsoil’s frequently low nutrient levels result in less crop protection for the soil through reduced crop output. He goes on to add that the effects of soil erosion go beyond the depletion of vital topsoil, crop emergence, and growth.Water’s erosivity

The physical characteristics of water’s erosivity forces are unrelated to the local climate. In actuality, various climatic conditions show various erosive powers of rainfall. In order to build a broadly predictive exponential equation, Van Dijk et al. (2002) critically analyze previously published research of rainfall intensities and kinetic energy. In addition to erosivity caused by rainfall droplets (splash effects), surface runoff (overland flow) forces also contribute to erosion. Landscapes in tropical regions that are semi-humid and semi-arid both experience saturated overland flow and surface runoff.According to Bryan et al. (1989), the erodibility of soil has not been precisely characterized. Bryan (2000) emphasizes the significance of soil’s natural resistance to erosion. The findings of his study indicate that several components.
