Water. As a result, the lack of land cover causes increased rates of soil erosion. Runoff washes away the soil particles from sloping and bare lands while wind blows … Water Runoff. Causes of Soil Erosion: Various agents, like wind, water, deforestation, overgrazing by cattle, and etc., cause soil erosion. Water runs off the parking lot onto nearby lands and speeds up erosion in those areas. The consequences of soil erosion are primarily centered on reduced agricultural productivity as well as soil quality. It results in the progressive down-slope movement of soil, causing severe soil loss on upper-slope positions and accumulation in lower-slope positions. When forests are wiped out, the land becomes exposed, leaving it vulnerable to being washed or blown away by elements. The causes of soil erosion are directly related to improper landuse, and are, therefore, entirely man-made. Soil erosion eats away the top soil which is the fertile layer of the land and also the component that supports the soil’s essential microorganisms and organic matter. The leaves and canopy of big, tall trees protects the soil from wind and rain. Erosion definition. Soil erosion is a gradual process that occurs when the impact of water or wind detaches and removes soil particles, causing the soil to deteriorate. If the texture is loose that is the soil contains more of small grains and of open structure erodes faster. Logging removes trees that protect the ground from soil erosion. Starting with the minor soil disruption caused by the impact of falling raindrops, splash erosion moves around small particles in the upper soil layer. Causes of Soil Erosion: Soil erosion is also referred to as the creeping death. Soil erosion is, thus, more common in desert or Barren land. The carrying away of dry soil and loose sand particles is known as deflation. Some Other Causes of Soil Erosion: 1. The accumulation of soil sediments in dams/drainages and along embankments can reduce their operational lifetime and efficiency. Sheet erosion affects a whole area, when water or the wind act like a broom to clear out the topsoil. This is because mass movements aids in the breakdown of the soil particles that makes them venerable to water and wind erosion. Apart from polluting the water systems, high soil sedimentation can be catastrophic to the survival of aquatic life forms. When the rivers and streams are full of soil deposits due to sedimentation and the valley levels up with the surface, the water ways begin to wash away the soils at the banks. Near construction sites, dirt, picked up by the wind, is often in the air. 2. Greater duration and intensity of rainstorm means greater potential for soil erosion. Depending on the type of force, erosion can happen quickly or take thousands of years. Water ways may also be blocked, and it may affect water quality. Off-road vehicles disturb the landscape and the area eventually develops bare spots where no plants can grow. Here are few of the major causes of soil erosion. Soil structure and composition is another factor that determines erosivity of wind or rainfall. Also, the silt up can support plant life that can, in turn, cause cracks and weaken the structures. Put simply, the causes of soil erosion are somewhat inevitable. What Is Soil Erosion? Luxury Landscape Supply explains the four common causes of soil erosion below. Why are National Parks Important and How Do They Help the Environment? Soil erosion is the washing away of the topsoil from one place to another by erosional agents like wind, water, animals, and glaciers. Causes of Soil Erosion. Trees and their roots provide the soil with an anchor, as well as shelter from the wind and rain. Deforested swatches in Brazil show up as gray amid the bright red tropical rainforest. Uneven distribution of rainfall. Factors like heavy rainfall, flooding, high winds, and even mass movements are part and parcel of the cyclical nature of soil. (a) ATVs churn up the soil, accelerating erosion. The transformation of natural ecosystems to pasture lands has largely contributed to increased rates of soil erosion and the loss of soil nutrients and the top soil. But, before we go into how to prevent soil erosion, you first need to understand what causes it. Soil erosion is a natural process which has increasingly been exacerbated by human activities such as agriculture and deforestation. The outcomes of soil erosion are reduced agricultural productivity, ecological collapse, soil degradation, and the possibility of desertification. Also Read: What is Soil? Weathered rock will be removed from its original site and transported away by a … Although soil erosion is a natural process, human activities have greatly accelerated it. Figure 6. The severity of soil erosion is also dependent on the soil type and the presence of vegetation cover. Soil erosion can affect infrastructural projects such as dams, drainages, and embankments. The effects of soil erosion include: Lands used for crop production have been substantially affected by soil erosion. Many of the tropical forests that remain are currently the site of logging because North America and Europe have already harvested many of their trees (Figure 4). Wind erosion happens when wind gusts blow away unsecured soil. (And Which Foods Do They Actually Like), How Do Birds Mate?
