Soil erosion refers to the removal of the top layer of soil, which is crucial for plant growth and agricultural productivity. The topsoil contains essential nutrients, organic matter, and microorganisms that support healthy plant development. When topsoil is eroded, the land becomes less fertile, making it more challenging to grow crops and leading to lower agricultural yields. This loss can substantially impact food production, water quality, and the overall health of ecosystems.

Soil erosion can occur through various processes, such as water runoff, wind, and human activities like deforestation and poor land management practices. This makes it a significant environmental concern, as it can lead to desertification in some areas, increased sedimentation in water bodies, and disruption of the natural balance in ecosystems. Understanding soil erosion's impact is vital for sustainable agriculture and land use planning.
