WWF advocates for governments, international bodies and other stakeholders to make zero net deforestation a reality by 2020. Soil compaction has far-reaching implications as it affects all stages of soil life. 4 How does soil erosion affect the topsoil? High levels of algae remove too much oxygen from the water, resulting in the death of aquatic animals and reduced fish populations, according to the World Wildlife Fund. All this interception prevents rain from directly hitting the soil which causes erosion as the droplets dislodge soil particles and wash them away, 3) Groups of trees in a woodland prevent wind erosion. The agents of soil erosion are the same as of other types of erosion: water, ice, wind, and gravity. Soil Erosion is the situation in which the particles of soil are loosened or are washed away or eroded in the rivers, streams, oceans, valleys, or distant lands. Washington DC 20002 Pesticides and other chemicals can get trapped in soil, polluting streams and rivers as the soil breaks apart. Knowing that soils are being lost at a dramatic rate, and also knowing that it is very difficult to grow food with poor soils, farmers are trying to move towards a low or no-till system of farming. kcse Erosion increases the amount of dust carried by wind, which not only acts as an abrasive and air pollutant but also carries about 20 human infectious disease organisms, including anthrax and tuberculosis. As you are probably aware, carbon in the atmosphere (in the form of carbon dioxide) is not something we need any more of. Trees, and other vegetation play a key role in holding soils together.

We mentioned that deforestation is one of the leading causes of soil erosion and therefore an easy way to counter this is by reforestation. It is estimated that around half the worlds topsoil (the nutrient rich upper layer of soil) has been lost to in the past 150 years, 20% of the worlds croplands are decreasing in productivity. When topsoil is eroded, yield suffers due to nutrient loss and damage to soil physical properties. This leads to plants dying which means that all of the roots disappear and their is nothing to hold the soil in place. The transition to agriculture from natural vegetation often cannot hold onto the soil and many of these plants, such as coffee, cotton, palm oil, soybean and wheat, can actually increase soil erosion beyond the soils ability to maintain itself. The leaves intercept and slow down raindrops meaning they have less momentum when the reach the soil, and secondly the trees absorb water from the soils making them less waterlogged and less prone to landslides. Planting new trees will gradually improve soil health as the roots bind the topsoil back together and the leaf litter which slowly rots on the ground will add to the layer of soil every year. Most of these activities are related to agriculture and so to slow them down we must look for more sustainable innovative solutions that can help restore and maintain the health of our precious soils.
