Roads that are cut into sloped surfaces such as hillsides or mountainsides are subject to the effects of erosion. The slope farming allows water to flow in furrows along a farm, thus eroding the soil in the process. 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. About 60 percent of soil that is washed away ends up in rivers, streams and lakes, making waterways more prone to flooding and to contamination from soil's fertilizers and pesticides. Soils sequester and store large amounts of carbon. This high nutrient topsoil is not easy to replace, it has Grasslands, for example, store a total or 343 gigatons of carbon in just the top one meter of soil. How does weathering and erosion affect humans? The effects of soil erosion go beyond the loss of fertile land. Other detrimental agricultural practices include farming on slopes and usage of pesticides and insecticides.

When humans disturb the earth with construction, gardening, logging and mining activities the result is a weakening of the topsoil of the earth, which leads to excessive wearing away and erosion. Soil has a considerable effect on human health, whether those effects are positive or negative, direct or indirect. Muskrat is an animal known to burrow holes near the banks of rivers and in the process makes the river banks weaker. kcse geography revision notes However, how rainfall affects runoff, soil erosion, and nutrient loss under different crop rotation patterns and topographic factors remains unclear. Soil is an important source of nutrients in our food supply and. We rarely know whether the tree listed on the label of wood products is accurateor legal. Soil erosion cause by wind (wind erosion) can cause eye and respiratory problems. necta csee past paper which is an example of erosion, and increased soil in the . Topsoil, which lies closest to the surface of the land, contains essential nutrients for crops. Soil erosion can lead to the soil running off into waterways, which increases the sedimentation of the water, and makes aquatic ecosystems inhospitable for those organisms that require clearer waters for their habitat. Some spatial distribution of soil animals is a result of ero- sion. Phosphorus is a limiting nutrient for aquatic organisms. Introduction. kcse geography When the soil is dense and of low porosity, roots have a harder time digging down through compacted layers to take hold. chemistry We use cookies on our website to give you the most relevant experience by remembering your preferences and repeat visits. As a growing human population cuts down forests and transforms natural landscapes into fields for agricultural crops and pasture land, the sustainable use of the worlds natural resources is becoming increasingly important. kcse WWF advocates for governments, international bodies and other stakeholders to make zero net deforestation a reality by 2020. This value includes lost productivity, along with sedimentationandwater pollution. Chen, Shiping, et al. history population studies The problem with annual plants is that because they are only around for a short time their root systems are very shallow staying near to the soil surface. I interviewed Ben Scott-Robinson, the founder of the Small Robot The travel industry is one of the worst offenders to environmental pollution and projections show that it is likely to continue growing. The key to managing and reducing soil erosion is to rehabilitate already-damaged land, stop further degradation and put erosion-preventative measures at the core of land management policy. Over time, abusive farming and agricultural tilling processes can result in nutrient degradation -- the decline in soil quality. While erosion is a naturally occurring process, human activity can accelerate it. Mudslides. that rely on this. 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. The smaller soil particles are easily carried by water or wind, resulting in soil erosion. Soil Acidity Levels. Also, the soil is covered with hard and impenetrable asphalt, tarmac or concrete, which increases the amount of surface runoff in case of a heavy downpour. The main threats include erosion, acidification, pollution, compaction, organic matter loss and salinisation. However, such effects go beyond controlling measure as the soil loses its productive capacities. How have human activities affected the rate of soil erosion? The effects of erosion degrade the landscape, making it less attractive from a recreational and aesthetic point of view; this can also affect the tourism economy. Climate change is also leading to an increase in more intense rainfall events. over the years. It can have a number of negative effects on both humans and animals. Increased demand for agriculture commodities generates incentives to convert forests and grasslands to farm fields and pastures. The cookie is used to store the user consent for the cookies in the category "Performance". Soil erosion decreases soil fertility, which can negatively affect crop yields. For example, in the Mediterranean, WWF developed a program to create a network of protected forests to integrate conservation and development so that local people would benefit from their natural heritage. The loss of fertile soil makes land less productive for agriculture, creates new deserts, pollutes waterways and can alter how water flows through the landscape, potentially making flooding more common. Soil Erosion. 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. Part of Springer Nature 2018 175 K. Lorenz and R. Lal, Carbon Sequestration in Agricultural Ecosystems, https://doi.org/10.1007/978-3-319-92318-5_4. Farmers are also rotating crops more frequently to allow This stimulates the growth of harmful bacteria at the expense of beneficial kinds.

Meaning that they are only around for one year rather than a perennial plant that remains over many years. The slope farming allows water to flow in furrows along a farm, thus eroding the soil in the process. These smaller machines reduces the requirement for large heavy machinery such civics Naturally, this may occur by wind, water, snow or ice as with all types of erosion.

The targeted pesticide application reduces the amount of pesticide that is needed Soil is the earths fragile skin that anchors all life on Earth. chemistry past paper water droplets are slowed right down and may either gradually make their way to This is not only a good deal for the farmer, but for the whole community. The reason for this is that erosion is caused by numerous factors, originating from both natural processes and human activities. Desertification is increased by over-settlement, over-grazing and over-cultivation. Erosion promotes critical losses of water, nutrients, soil organic matter and soil biota, harming forests, rangeland and natural ecosystems. Insecticides and pesticides may destroy organisms which help in making the soil coherent thereby promoting erosion. Some companies are taking an even more innovative approach Soil erosion is a natural process but one that is being rapidly accelerated due to human activities. This makes the soil infertile and not nutritious. Annual crops also have to be re-sown each year which means more disturbance of the soils every year. This may cut off transportation lines. That is equivalent to 3.4 tons for each human being. What are the major effects of soil erosion Class 10? ; Bartarya, S.K. Soil erosion is a natural process that we cannot stop. The gradual erosion of soil creates sedimentation, a process by which rocks and minerals in the soil separate from the soil and deposit elsewhere, often lodging in streams and rivers.
