Erosion control refers to the practices and materials used to prevent or reduce soil erosion caused by wind, water, or human activity. These techniques aim to stabilize soil, protect vegetation, and prevent sediment from being washed away, which can lead to land degradation and water pollution. Common erosion control methods include the use of mulch, retaining walls, erosion control blankets, and plantings that anchor the soil in place. Erosion control is critical in landscaping, construction, and agricultural settings to preserve soil health and prevent environmental damage.
