Soil erosion is the process where the top layer of soil is worn away by natural forces like wind, water, or human activity. This layer, rich in organic material and essential nutrients, supports plant growth and sustains ecosystems. When erosion occurs, it reduces soil fertility, harms agricultural productivity, and can lead to barren landscapes. Water erosion, caused by rainfall or runoff, can create gullies and wash away large quantities of soil. Wind erosion is prevalent in dry regions, where loose soil particles are easily blown away. Human activities such as deforestation, overgrazing, and improper farming practices accelerate erosion, stripping the land of its protective vegetation. Over time, soil erosion can lead to desertification and loss of arable land, posing a threat to food security and the environment. Preventive measures like reforestation, terracing, and conservation tillage are vital in reducing soil erosion and preserving soil health.
