Angola is located on the western Atlantic Coast of Southern Africa between Namibia and the Republic of the Congo.It also is bordered by the Democratic Republic of the Congo and Zambia to the east. Wind Erosion is the natural process of transportation and deposition of soil by the wind. causes were natural or conse quences of unwise use (Tann er, 2012). the grass roots are very good binders of soil. Bare soil is easily swept away by wind and water, the two main causes of erosion. Soil degradation and erosion are global problems associated with climate change and global warming. Lets have a look at the most common causes of soil erosion. Due to soil erosion, the soil becomes less fertile. This is a never-ending human tragedy that is responsible for causing all types of environmental issues. Excessive erosion leads to loss of soil, ecosystem damage, and a buildup of sediments in water sources. Tillage is the agricultural preparation of soil by mechanical agitation of various types, such as digging, stirring, and overturning. Water is one of the strongest erosive agents that has a great potential to disturb the soil surface. Supplementary feeds are given when the grass is poor and dry or when an animal is pregnant, giving milk or is a working animal. It is important to learn more about the signs of erosion so that it can be prevented. The depletion of forests lead to loosening of soil particles due to lack of roots and moisture in soil. The agricultural plants that often replace the trees cannot hold onto the soil and many of these plants, such as coffee, cotton, palm oil, soybean and wheat, can actually worsen soil erosion. Erosion is a natural process, though it is often increased by humans' use of the land. Examples of human-powered tilling methods using hand tools include shoveling, picking, mattock work, hoeing, and raking.Examples of draft-animal-powered or mechanized work include ploughing (overturning with moldboards or chiseling with chisel Slightly inland and parallel to the A loss of soil fertility is another form of degradation. Soil erosion - this is made worse by overgrazing and the removal of wood. Excessive erosion leads to loss of soil, ecosystem damage, and a And as land loses its fertile soil, agricultural producers move on, clear more forest and continue the cycle of soil loss. Plant grass and shrubs. For agricultural land in particular, the main causes of erosion might be intensive cultivation, overgrazing by livestock, poor management of arable soils, and the clearing of land to convert it to land for farming (although it differs between developed and developing countries industrial agriculture vs pasture grazing for example). Overgrazing occurs when a piece of land is overused by livestock. Overgrazing makes the soil unusable since the land is unable to keep up with the needs of the livestock. Causes and effects of soil erosion: Soil erosion is a natural process which has increasingly been exacerbated by human activities such as agriculture and deforestation. Soil erosion occurs primarily when dirt is left exposed to strong winds, hard rains, and flowing water. Such wild rabbit populations are a serious mammalian pest and invasive species in Australia causing millions of dollars worth of damage to crops. Supplementary feeds. Massive amount of vegetation gets eaten and lost which accelerates the rate of soil erosion. The Good News. Generally, soil erosion is a two-step process consisting of the detachment of particles from the soil mass and transport by erosive factors such as runoff. These practices should be avoided as they play a part in expediting soil erosion. Causes of Soil Erosion. Hugh H. Bennett, point for silt loam soil erosion rates that increased by over one. The soil may also become compacted, which further limits the ability of vegetation emerging in that area. These loosened particles are more prone to soil erosion by winds. The country consists of a sparsely watered and somewhat sterile coastal plain extending inland for a distance varying from 50 to 160 km (31 to 99 mi). This is a large threat in the Central Asian rangelands, like Mongolia and Kazakhstan. Meat production is one of the leading causes of greenhouse gas emissions and other particulate matter pollution in the atmosphere. The problems caused by soil erosion include: Natural hazards are excluded as a cause; however human activities can indirectly affect phenomena such as floods and bush Overgrazing also causes loss of natural vegetation and compaction of the soil, disrupting the balance of natural microorganisms and often promoting the growth of harmful bacteria as well as contributing to the problems caused by erosion [17]. Soil Erosion. 1 Fluvial erosion and badlands are the results of many hydrogeomorphic processes. In addition to the loss of soil, erosion reduces soil nutrients and organic matter, thereby impacting lands productive capacity. For example, soil erosion by water causes global losses of as much as 42m tonnes of nitrogen and 26m tonnes of phosphorus every year. European rabbits (Oryctolagus cuniculus) were first introduced to Australia in the 18th century with the First Fleet, and later became widespread likely because of Thomas Austin. Erosion is the action of surface processes (such as water flow or wind) that removes soil, rock, or dissolved material from one location on the Earth's crust, and then transports it to another location where it is deposited.Erosion is distinct from weathering which involves no movement. Land degradation is a process in which the value of the biophysical environment is affected by a combination of human-induced processes acting upon the land. Climate change in a broader sense also includes previous long-term changes to Earth's climate. They are loosely divided into causes, effects and mitigation, noting that effects are interconnected and can cause new effects. Soil restoration begins with photosynthesis. This leaves the soil exposed to erosion. Their spread may have been enhanced through Plant roots hold the soil together, while their leaves block rain and stop it from breaking the soil apart. The soil becomes exposed and gets eroded by the action of strong wind, rainfall etc. Despite efforts taken by the government in terms When the soil has faced overgrazing or has a lack of vegetation cover, it can lead to a higher rate of erosion. 5. Prolonged Effects of Overgrazing 1. Although soil erosion is a natural process, it is often accelerated by human activities, for example by the clearing of vegetation, soil tillage or overgrazing. What is wind erosion? This type of It is a common phenomenon occurring mostly in dry, sandy soils or anywhere the soil is loose, dry, and finely granulated. Overpopulation. Deforestation, overgrazing, construction, and road building often expose soil and sediments and lead to increased erosion. According to some estimates in non This is because the animals will graze even on the slightest shoots of new growth. The trees stop soil erosion and improve the fertility of the soil. Imagine there was a process that could remove carbon dioxide (CO 2) from the atmosphere, replace it with life-giving oxygen, support a robust soil microbiome, regenerate topsoil, enhance the nutrient density of food, restore water balance to the landscape, and increase the profitability of agriculture. When the grasses are removed, the soil becomes loose and susceptible to the action of wind and water. Soil erosion associated with overgrazing is an important issue in many dry regions of the world. Sheep, cattle and goats are overgrazing the vegetation. Desertification is a type of land degradation in drylands in which biological productivity is lost due to natural processes or induced by human activities whereby fertile areas become increasingly arid. The process of soil formation and soil erosion occurs at a simultaneous rate and there is a balance between them. Various agents, like wind, water, deforestation, overgrazing by cattle, etc., cause soil erosion. The removal of topsoil by the natural forces is known as soil erosion. Poor farming practices as well as the trend toward agricultural intensification have been considered to be major causes of erosion. Tunnel erosion causes the loss of soil from the subsoil layer. What is less discussed is the impact of overcropping and overgrazing. According to Global Assessment of Soil Degradation (GLASOD), deforestation is the main cause of soil erosion by wind in about 98% of the area. Water pollution, resources crisis, gender imbalance, pollution, land pollution, urban sprawling, deforestation, over production are some common examples of dangerous effects cause by overpopulation.. To illustrate, soil erosion by water is estimated to result in the loss of 2342 Mt of nitrogen and 14.626.4 Mt of phosphorus from soils globally each year (Pierzynski et The current rise in global average temperature is more rapid than previous changes, and is primarily caused by humans But sometimes, this balance is disturbed due to factors which include human activities like deforestation, overgrazing, construction and mining etc., and natural forces like wind, glaciers and water. Soil Erosion of a Piece of Land. (ii) Water Erosion: Deforestation, overgrazing and mining, all are equally responsible for an increase in the rate of erosion by water. Causes of Soil Pollution the exposed soil is easily carried away during soil erosion. It is viewed as any change or disturbance to the land perceived to be deleterious or undesirable. Erosion is the process by which rock and soil are removed from the surface of the Earth as a result of water and wind action and thereafter deposited to other areas on the Earths surface. In common usage, climate change describes global warmingthe ongoing increase in global average temperatureand its impacts on Earth's climate system. (ii) Soil Erosion: Due to overgrazing by cattle, the cover of vegetation almost gets removed from the land. Erosion is a natural process, though it is often increased by humans use of the land. The continued trampling of numerous animals in an average forage land will act to accelerate the death of plants and vegetation cover. Few Causes of Soil Erosion: Unsustainable livestock management can lead to overgrazing and a decrease in ground cover. The Power of Photosynthesis. While erosion is a naturally occurring process, human activity can accelerate it. The top layer of soil is very light which is easily carried away by wind and water. Causes of soil erosion Wind and water are the main agents of soil erosion. Natural causes of soil erosion #1 Water runoff and rainfall. Wind erosion damages land and natural vegetation by removing soil from one place and depositing it in another. Overgrazing can be caused by a number of factors, including short-term climatic changes , changes in the With the soil taken away, the land is left unable to support vegetation. Ask your agriculture officer or veterinarian about using fodder trees. The best supplementary feed is cake. Turf, ornamental grass, and low, spreading shrubs work best since they cover the soil completely. Deforestation, overgrazing, construction, and road building often expose soil and sediments and lead to increased erosion. Overgrazing is one of the principal causes of soil erosion. order of magnitude at 11.6 m s. It is the spread of arid areas caused by a variety of factors, such as climate change and overexploitation of soil as a result of human activity. The amount of soil they can carry away is influenced by two related factors: speed - the faster either moves, the more soil it can erode; plant cover - plants protect the soil and in their absence wind and water can do much more damage. This can be through a loss of nutrients, such as nitrogen, phosphorus and potassium, or a decline in the amount of organic matter in the soil.
