Human activies such as deforestation, overgrazing, and intensive agriculture remove the protective vegetation canopy and root systems, exposing soil to raindrop impact and runoff.

Prevention andMitigation Strategies

Combating soil erosion requises a combination of land- use practices, investering interventions, and policy measures that maintain or reconcere soil health and vegetation cover. No single solution works everywhere; strategies mudt be tailode to local climate, soils, and land- use systems.

Agricultural Conservation Practices

In farming systems, conservation tillage (including no- till and reduced-till) leafes crop residue on thee soil surface, reducting raindrop impact and runoff. Cover crops such as rye, clover, or vetch are planted during fallow period to shield thee soil andd organic matter.

Grazing management is critial in rangelands.

Reforestation andd Landscape Restoration

Restoring forests andd natural vegetation on degraded slopes is one of thee most effective long-term erosion control measures. Trees and shrubs contract rainfall, their roots bind soil, and leaf litter creats a protective mulch layer.
