Land degradation negatively impacts the supply of fresh water by reducing the soil's ability to retain moisture and filter water. Deforestation, erosion, and urbanization can lead to increased runoff and sedimentation in waterways, diminishing water quality and availability. Additionally, degraded landscapes often disrupt natural hydrological cycles, resulting in altered precipitation patterns and reduced groundwater recharge. Consequently, these changes can exacerbate water scarcity and threaten ecosystems and human populations reliant on clean water sources.
