All on erosion, a full guide? What is soil erosion and soil degradation? Although soil erosion is a natural process, human activities over the past decades have greatly accelerated it. In fact, according to the UNESCO, land degradation is undermining the well-being of two-fifths of humanity, driving species extinct and intensifying climate change. According to a senior UN official, all of the world’s topsoil could be gone within 60 years.

Every year, rivers deposit millions of tons of sediment into the oceans. Without the erosive forces of water, wind, and ice, rock debris would simply pile up where it forms and obscure from view nature’s weathered sculptures. Although erosion is a natural process, abusive land-use practices such as deforestation and overgrazing can expedite erosion and strip the land of soils needed for food to grow.

Continued deflation of loose particles from landforms leaves behind larger particles that are more resistant to deflation. Wind action transports eroded material above or along the surface of Earth either by turbulent flow (in which particles move in all directions) or by laminar flow (in which adjacent sheets of air slip past one another). The transportation of wind-eroded material continues until the velocity of the wind can no longer sustain the size particle being transported or until the windblown particles collide with or cling to a surface feature.

Climate change may strongly influence soil erosion risk, namely through variations in the precipitation pattern. Forests may contribute to mitigate the impacts of climate change on soil erosion and forest managers are thus challenged by the need to define strategies that may protect the soil while addressing the demand for other ecosystem services. Our emphasis is on the development of an approach to assess the impact of silvicultural practices and forest management models on soil erosion risks under climate change.

Soil erosion removes the topsoil that is necessary for organic matter, nutrients, micro-organisms that are required for plants to grow and shine. Soil conservation is one such step that protects the soil from being washed away. The soil then ends up in aquatic resources bringing in pesticides and fertilizers used on agricultural land. Healthy soil is important for plants to grow and flourish. Taking the necessary steps to conserve the soil as part of an environmentally friendly lifestyle. There are several ways to conserve soil that can be done through agricultural practices or measures you take at home.
