Data on wind erosion
Our natural environment includes a number of elements that are affected in amount by the presence of external forces such as wind, water and ice. The soil, rocks and sediment from the beds of rivers and mountainous terrain are displaced by these forces regularly, so it has been forever. While the force of gravity is the main factor influencing the burrowing animals, as well as atmospheric chemical and physical effects, which are also responsible for the erosion.
Erosion is a natural process that occurs with the slightest change in speed or movement of the force responsible. Wind erosion is a process naturalpero can also be induced or augmented through the abuse of land, deforestation, uncontrolled construction, overgrazing, and urbanization.
The wind speed plays an important role in the movement of the soil surface. Soil erosion not only disturbs the balance between soil structure and plant roots, but also alters the terrace cultivation in a big way. Conservation practices in agriculture for plowing and sowing significantly affected by wind erosion.
An ecosystem allows a certain amount of erosion, however, lost ground in large quantities it takes a long time to be replaced and also damages the delicate balance of nature.
The wind erosion rate depends on rainfall, temperature, wind speed and soil and rock type it is. These geological factors affecting the welfare of the natural vegetation, living organisms and human life.
Ecosystems, with high intensity winds are likely to be subjected to more erosion. The content of sediment and silt on slopes are lost in the presence of strong winds. The resulting removal of a deposit area and the other affects the porosity and permeability of the surface.
Land cover, both litter and organic layers, remains firm roots embedded and compacted rocks are stable due to precipitation and pressure. However, the construction of roads and buildings and indiscriminate deforestation increases the rate of wind erosion.
The wind can easily blow up sediment and soil cover has come loose due to human action. This happens because the patterns of effects of drainage, retaining walls and soil compaction, leading to exposure of mineral soil. Intensive grazing and drastic changes in vegetation also widen the rate of wind erosion.
Logging, burning and shifting cultivation coverage not only expose the soil to wind erosion, but also affect the habitat of endemic organisms. Such treatments also make an unproductive region. The soil in a region gradually degenerates and becomes less fertile.
Sad but true, nearly 40% of agricultural land available on earth have been degraded. The increase in human and animal activities make it easier to wind erosion, which is very harmful to any ecosystem.
Overcrowding has influenced the removal of vegetation for construction and roads for vehicles, which in turn this leads to large losses of soil by wind speed. The process of erosion involves the movement of sediment from higher to lower altitude, with early results and very disastrous.
The mechanisms of displacement are the manifestation of the changes in topography. The depressions formed magnify the impact of engineering along the soil surface. Wind erosion gives effect to the deflation of surface sediments of the succession. Global air temperature and precipitation intensity leads to a higher rate of wind erosion.
