Which practice can lead to increased erosion if not properly managed?

Overgrazing can lead to increased erosion if not properly managed because it removes vegetation cover from the soil, exposing it to the elements. When livestock graze excessively, they can strip away grass and other plants that normally stabilize the soil with their root systems. As a result, the soil becomes more susceptible to erosion by wind and water, leading to sediment loss and degradation of the land. Without adequate plant cover, rainfall can create runoff that washes away the topsoil, which is vital for agricultural productivity and ecosystem health. Proper management, such as controlled grazing and rotational practices, is essential to maintain soil health and prevent erosion associated with overgrazing.

In contrast, practices like crop rotation, planting cover crops, and mulching are typically aimed at enhancing soil structure, increasing organic matter, and providing necessary cover to protect the soil from erosive forces. These practices, when implemented correctly, can help reduce erosion rather than increase it.
