Soil erosion is the result of natural physical forces, such as water and wind, gradually wearing away the topsoil in a field. [5] This process can be slow and inconspicuous or occur rapidly, leading to significant topsoil loss. [5] Apart from soil erosion, there are other severe soil degradation issues, including soil compaction, reduced ...
Since erosion plays a large role in soil depletion in this area, it is important to consider fertilization and irrigation when attempting to grow crops. [6] Poorly terminated drain, a major cause of gully erosion. Climate in Nigeria has an extreme impact on the gully formations. For an area that is predominantly dry, the intensity of the rain ...
In northern Nigeria, this has been associated with an average temperature increase of at least 1 °C. [61] Increased Erosion: Loss of soil's natural vegetation cover due to desertification is a major driver of soil erosion, with wind and water erosion causing widespread degradation (Katsina State survey).
Forests maintain soil fertility and prevent erosion. Deforestation causes soil erosion, reducing agricultural productivity and causing soil loss and gullies. Aquatic trees’ roots, critical for fish and other species, diminish due to deforestation. Logging of a healthy ancient tree leading to gutter destruction, pavement destruction and road ...
Soil erosion is the main factor for soil degradation and is due to several mechanisms: water erosion, wind erosion, chemical degradation and physical degradation. Erosion can be influenced by human activity. For example, roads which increase impermeable surfaces lead to streaming and ground loss.
Soil degradation: Bush burning destroys the organic matter and nutrients in the soil, making it less fertile and productive. It also reduces the soil moisture and increases the soil temperature, making it more susceptible to erosion and compaction. It also alters the soil pH and microbial activity, affecting the soil quality and health. [3] [4] [6]
In Nigeria, natural forests have reduced drastically and its impacts on climate change are increasing. Erosion and excessive wind reduces the amount of forestry produce, such as wood and cane. [76] Forests are under significant pressure not only from climate change but also from increasing populations and greater demand for forest resources. [56]
Agricultural productivity, ecosystem stability, and sustainable development are all impacted by soil erosion and land degradation. [49] [50] Natural forces like wind, water, or human activities can cause soil particles to be detached, transported, and deposited elsewhere.
