The major effects of soil erosion include: Loss of fertile land: Due to Soil erosion, the top layer is the fertile layer (which contains all the organic compounds required for the growth of plants) which means there is fertility loss of soil, The soil which has no fertility or the top layer leads to non-productive fields. This is a global problem. (3). The livestock eat away the vegetation, thereby leaving the land bare for wind and water to act upon. The effects of soil erosion go beyond the loss of fertile land. It causes pollution and reduces the water quality. The amount of soil erosion from farmland can be directly attributed to the level of tillage undertaken on the land. That means the forests and rivers of the DRCthe second largest country in Africa and one of the fastest growing countries in the worldare now on the frontlines. And degraded lands are also often less able to hold onto water, which can worsen flooding. Larger soil animals (meso- and macrofauna) are also affected by soil compaction. Long Term Erosion. Pollutants in the soil, such as fertilizers and pest control agents used to protect crops, also settle in the streams and rivers. When land degrades, it destroys habitats and decreases the amount of land available for agricultural needs or the needs of wildlife. Meaning that they are only around for one year rather than a perennial plant that remains over many years. It has led to increased pollution and sedimentation in streams and rivers, clogging these waterways and causing declines in fish and other species. Soil erosion also reduces the ability of soil to store water and support plant growth, thereby reducing its ability to support biodiversity. Some of the greatest effects of soil erosion include: Loss of Topsoil. Perennial crops have much deeper, more complex root systems that do a much How does weathering and erosion affect humans? What is the role of animals in the process of erosion? In growing crops, humans invest money in purchasing inputs such as seeds, fertilizers, and pesticides among others.

This prevents erosion of soils further as winds are less powerful and so less likely to blow away any of the top soil layer. Each year around 75 billion tons of soil is eroded worldwide and soil is being lost at 13 to 40 times as fast as it is naturally being replaced. ; Rai, S.P. Erosion effects humans by adding additional toxic organic chemicals and heavy metals to the soil as well as eroding land so that there is less land to farm on. that rely on this. Erosion of earthworms down hillsides has also been observed (Atlavinyt~, 1965}. current annual system. Seeds and plants can be disturbed or completely removed by the erosion. amounts of deforested land. Better land management can help keep soils intact so they can grow more carbon-sucking vegetation. Reduction in crop yield. This is as a result of breaking the soil into very small pieces during the dry seasons, allowing wind action to carry the top soil layer. As you are probably aware, carbon in the atmosphere (in the form of carbon dioxide) is not something we need any more of.
