The effects of soil erosion go beyond the loss of fertile land. It has led to increased pollution and sedimentation in streams and rivers, clogging these waterways and causing declines in fish and other species. And degraded lands are also often less able to hold onto water, which can worsen flooding.
7 Φεβ 2020 · Soil erosion decreases soil fertility, which can negatively affect crop yields. It also sends soil-laden water downstream, which can create heavy layers of sediment that prevent streams and rivers from flowing smoothly and can eventually lead to flooding.
24 Αυγ 2018 · Soil erosion is an ongoing process that affects each site in a slightly different way. Its effects can be seen directly in the location where erosion takes place, known as on-site effects, and at the site where the eroded soil deposits – off-site. Let’s first have a look at the problems on-site erosion brings.
The cause of the erosion is over grazing due to goats and other livestock. The exposed bare earth is washed away forming the gully system. Deforestation in the Lake Bogoria area is a serious threat as it leads to a drop in the water table and therefore streams and swamps drying out.
Erosion from the wind causes particles of soil to become suspended in the air. Although this occurs naturally, degraded, drier soils are more susceptible to wind erosion causing an increase in overall air pollution in certain areas.
All soils undergo soil erosion, but some are more vulnerable than others due to human activities and other natural causal factors. The severity of soil erosion is also dependent on the soil type and the presence of vegetation cover. Here are few of the major causes of soil erosion. Rainfall and Flooding.
26 Φεβ 2016 · Soil erosion can lead to the soil running off into waterways, which increases the sedimentation of the water, and makes aquatic ecosystems inhospitable for those organisms that require clearer waters for their habitat.
