How can soil erosion impact agriculture?

Soil erosion significantly affects agriculture by reducing the available arable land. This occurs when topsoil, which is rich in nutrients and essential for plant growth, is washed or blown away. As the fertile top layer diminishes, the land's productivity declines, making it less suitable for farming. This results in decreased crop yields and can lead to challenges in food production.

Over time, persistent soil erosion can lead to land degradation, reducing the total area that can be effectively farmed. The challenge is compounded by factors such as deforestation, overgrazing, and improper agricultural practices, which can exacerbate erosion issues, further limiting the land available for sustainable agricultural practices. The consequences are not only economic but also ecological, as it can contribute to habitat loss and biodiversity decline.
