Question

Define soil erosion.

Answer 1

Hint:A big factor in desertification is soil erosion. It transforms inhabitable areas into deserts. The situation is exacerbated by deforestation and disruptive land use. This also results in the depletion of biodiversity, soil erosion, and habitat change.
For farmers and the population who rely on agriculture for food and jobs, the health of the soil is of the utmost importance. In order to resist soil erosion, there are many problems, but there are also solutions to avoid it.

Complete answer:
Soil erosion -
In this method soil particles in valleys, seas, rivers, streams or far-flung lands are loosened or washed away. The impact of human activities such as farming and deforestation has been declining.
Soil erosion is an ongoing, slow or worrying, phenomenon of soil. This leads to a constant depletion of topsoil, environmental deterioration, soil collapse and so on.
Causes of Erosion of Soils –
Precipitation and Flooding
The Agriculture
From Grazing
Logging and Extraction
Rivers and Flows
The Winds Strong
Features of soil erosion -
It is the normal process of wearing away the topsoil, but the process has been intensified by human operations. It is generally caused by vegetation removal or other action that makes the field dry.
Some of the causes of soil erosion are farming, grazing, mining, construction and recreational activities.
Soil erosion's consequences are not just land loss. It has contributed to a dramatic rise in river contamination and sedimentation, which obstructs the water sources, resulting in a reduction in the aquatic organism population.
Degraded land loses the ability to carry water, resulting in floods.
To curb this question, steps should be taken. Some of the soil erosion mitigation strategies are below-
- Plant trees to restrict soil erosion on barren land.
- To stop soil erosion, apply mulch and rocks to prevent the plants and grass beneath.
- In order to minimize erosion on the slopes, mulch matting may be used.
- To prevent any water or soil from washing away, put a collection of fibre logs.
- A wall at the base of the slope can help avoid the eroding of the soil.
- In order for water to flow through sufficient water collection systems, every household should have a proper drainage system.

Note:The upper fertile layer of the soil is removed by soil erosion. This layer is rich in the vital nutrients the plants and the soil require. Degraded soil does not support the production of crops and contributes to low productivity of crops.
Soil erosion is a phenomenon that happens naturally that affects all landforms. Soil erosion in agriculture refers to the stripping away of the topsoil of a field by the natural physical forces of water and wind or by forces linked to agricultural practices such as tillage.
