Soil Erosion and Soil Conservation

• Soil erosion is the removal of the top fertile layer of soil by water, wind, and human activities.
• Soil erosion by water includes sheet erosion, rill erosion, gully erosion, leaching, sea erosion, and stream-bank erosion.
• Wind erosion occurs in dry and semi-arid regions where loose soil is carried away by strong winds, reducing soil fertility.
• Human activities such as deforestation, overgrazing, improper farming, and shifting cultivation greatly increase soil erosion.
• Soil erosion reduces agricultural productivity, leads to land degradation, and creates a cycle of poverty.

• Soil conservation means protecting soil from erosion and maintaining its fertility.
• Soil erosion causes loss of fertile topsoil, leading to reduced agricultural productivity.
• Soil conservation helps maintain soil moisture and raise the groundwater level.
• It prevents silting of rivers, floods, droughts, and landslides, especially in hilly areas.
• Soil conservation is essential because soil forms very slowly but can be destroyed quickly, and it supports plants, animals, and human life.

The loss of soil or disturbance of the soil structure is called soil erosion.
