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.

How does soil erosion affect animals?
Soil is loosened by the livestock hoof as well as grazing impacts on pastures and hence it becomes more prone to erosion by wind or rainfall. Also, livestock can overgraze vegetation, disrupting its role of trapping and stabilizing soil and aggravating erosion and pollution[3].
What are the effects of erosions?
Other effects of erosion include increased flooding, increased sedimentation in rivers and streams, loss of soil nutrients' and soil degradation, and, in extreme cases, desertification. It becomes harder to grow crops on eroded soils and local flora and fauna typically suffer.
How does erosion affect the ecosystem?
Soil erosion also reduces the ability of soil to store water and support plant growth, thereby reducing its ability to support biodiversity. Erosion promotes critical losses of water, nutrients, soil organic matter and soil biota, harming forests, rangeland and natural ecosystems.
How does water erosion affect wildlife?
Effects on Wildlife
The adverse effects of water erosion eventually lead to wildlife. Because the absence of the topsoil reduces water quality and increased pollutants, animals, fish and algae are negatively effected. ... Excessive topsoil could conceal fish breeding areas and pollute downstream waters.
How does livestock affect soil erosion?
Activity of livestock hooves in and around streams can degrade stream banks, destroy soil structure, and increase the likelihood of soil being suspended in water. Producers who use streams for watering livestock should consider fencing livestock away from surface water and using alternative water delivery systems.
How does soil erosion affect agriculture?
Soil erosion inhibits our ability to grow nutritious food.
By decreasing the nutrients available to plants as well as the space for them to put down roots, soil erosion can decrease crop yields by up to 50 percent. In addition, crops that do grow tend to be of a lower quality: misshapen, smaller and less nutritious.
What are the causes of erosion and the negative effects?
Soil compaction, low organic matter, loss of soil structure, poor internal drainage, salinisation and soil acidity problems are other serious soil degradation conditions that can accelerate the soil erosion process. This Factsheet looks at the causes and effects of water, wind and tillage erosion on agricultural land.
How does soil erosion affect the economy?
One study estimated global economic losses from soil erosion to be around $8 billion, due to reduced soil fertility, decreased crop yields and increased water usage. ... This value includes lost productivity, along with sedimentation and water pollution. Lost farm income is estimated at $100 million per year.
How are erosion and deforestation related to each other?
Deforestation. Deforestation is a major cause of soil erosion, perhaps the main cause. Trees and their roots provide the soil with an anchor, as well as shelter from the wind and rain. When forests are wiped out, the land becomes exposed, leaving it vulnerable to being washed or blown away by elements.
Does erosion affect wetlands?
Soil erosion and sedimentation also result in damaged and destroyed wetland habitat. Sedimentation of wetlands reduces wetland productivity, degrades wildlife habitat, and can eventually result in the loss of the wetland itself by infilling. ... This sedimentation is the end result of soil erosion.
How do erosions affect water systems?
Suspended sediment decreases the penetration of light into the water. This affects fish feeding and schooling practices, and can lead to reduced survival. Suspended sediment in high concentrations irritates the gills of fish, and can cause death.
How does wind erosion affect the environment?
Not only does wind erosion damage the land by drying out the soil and reducing the nutrients of the land, but it can also cause air pollution. Enveloping crops, covering highways, and invading homes, the sand, dust and dirt created from wind erosion can impact plant and human life in numerous ways.
How does erosion affect biodiversity?
In some cases, the eroded soil is so disturbed that the landscape becomes completely barren, and not much plant life will even grow there anymore. This barren landscape ultimately leads to a major decrease in ecosystem biodiversity for many organisms that can no longer live there.
How does animal grazing affect soil?
Through hoof action, pawing, and wallowing, grazing animals trample plants, break up soil surfaces, incorporate seed into the soil, and compact soils. Grazing animals contribute to nutrient cycling by depositing nitrogen-rich urine and dung, and their carcasses can provide an important contribution to the food web.
How does cattle grazing affect soil erosion?
The roughness could decrease SOC erosion when compared with un-grazed grassland. Many studies have emerged to suggest that grazing could increase soil surface roughness. For instance, Betteridge et al. (1999) found that grazing, particularly by cattle, increased soil displacement and roughness of soil surface.
