The agents of soil erosion are the same as the agents of all types of erosion: water, wind, ice, or gravity. Running water is the leading cause of soil erosion, because water is abundant and has a lot of power. Wind is also a leading cause of soil erosion because wind can pick up soil and blow it far away. Activities that remove vegetation, disturb the ground, or allow the ground to dry are activities that increase erosion.

Major Causes and Effects of Soil Erosion on People and the Environment

Soil erosion is one of the main factors causing land degradation. Furthermore, loss of soil nutrients ultimately causes worldwide reduction of agricultural productivity and water quality deterioration. Therefore, soil erosion control measures are required as an aspect of catchment management. The general purpose of this paper review is to make an overview of soil erosion throughout the world in order to highlight required studies on which to be based when proposing appropriate erosion control measures for agricultural fields. Different scientific documents including journal articles, internet materials, conference papers and books were used as research materials to achieve the objectives of the present work.

Soil erosion is a gradual process that occurs when the impact of water or wind detaches and removes soil particles, causing the soil to deteriorate. Soil deterioration and low water quality due to erosion and surface runoff have become severe problems worldwide. The problem may become so severe that the land can no longer be cultivated and must be abandoned. Many agricultural civilizations have declined due to land and natural resource mismanagement, and the history of such civilizations is a good reminder to protect our natural resources. Erosion is a serious problem for productive agricultural land and for water quality concerns.

Soil erosion is a naturally occurring process that affects all landforms. In agriculture, soil erosion refers to the wearing away of a field's topsoil by the natural physical forces of water Figure 1 and wind Figure 2 or through forces associated with farming activities such as tillage. Erosion, whether it is by water, wind or tillage, involves three distinct actions — soil detachment, movement and deposition.

Soil erosion is the most serious precursor of soil degradation that comes with global implications. Nearly 10 million hectares of arable land are lost to erosion and other forms of soil degradation every year [1]. Countries all over the world are battling with worrisome sight of deepening gullies crisscrossing the landscape and barren fields stripped of the fertile topsoil. Even the costs of losing such an important resource are incredibly high. If we will not take necessary steps to prevent the accelerating loss of our precious soils, there might come a time when we will not be able to produce enough food to feed growing population or harvest natural resources that require soils as a medium for growth.

Soil Erosion and Degradation: Simple Definition, Causes, Consequences

Soil erosion is a process that involves the wearing away of the topsoil. The process involves the loosening of the soil particles, blowing or washing away of the soil particles, and either ends up in the valley and faraway lands or washed away to the oceans by rivers and streams. Soil erosion is a natural process which has increasingly been exacerbated by human activities such as agriculture and deforestation. The wearing away of the topsoil is driven by erosion agents including the natural physical forces of wind and water, each contributing a substantial quantity of soil loss annually.

This is particularly true for places with the highest risk of erosion , such as watersheds in Indonesia, India, the Philippines and more. In these areas, protecting against soil erosion through sustainable land management can solve a multitude of problems. Soil is a natural resource that may look robust and endless, but is in fact the fragile product of thousands of years of formation.

Soil erosion: An agricultural production challenge

Simply put, it is when topsoil, which is the upper-most layer of the ground, is moved from one spot to another. Why this matters is because topsoil is the part of the land that is highest in organic matter and best suited for farming and other fertile activities, which is why soil erosion can have the greatest impact on farmers and agricultural land. Essentially, all life depends upon the soil … There can be no life without soil and no soil without life; they have evolved together. When farming activities are carried out, the topsoil is exposed and is often blown away by wind or washed away by rain. According to Wikipedia ,. Soil erosion is a naturally occurring process on all land. The agents of soil erosion are water and wind, each contributing a significant amount of soil loss each year.

Сьюзан на минуту задумалась. - Склонность к ребячеству, фанат сквоша с подавляемой сексуальностью. Беккер пожал плечами: - Не исключено, что ты попала в точку. Так продолжалось несколько недель. За десертом в ночных ресторанах он задавал ей бесконечные вопросы. Где она изучала математику. Как она попала в АНБ.

 Понятия не имею. Я уже говорила, что мы ушли до их прибытия. - Вы хотите сказать - после того как стащили кольцо. - Мы его не украли, - искренне удивилась Росио.  - Человек умирал, и у него было одно желание. Мы просто исполнили его последнюю волю. Беккер смягчился.

Лицо коммандера выражало торжественную серьезность. Видимо, в его действиях было нечто такое, что ей знать не полагалось. Сьюзан опустилась на стул. Повисла пауза. Стратмор поднял глаза вверх, собираясь с мыслями. - Сьюзан, - наконец произнес он еле слышно.  - У меня нет семьи.

Охранник залюбовался Сьюзан, шедшей по бетонной дорожке. Он обратил внимание, что сегодня взгляд ее карих глаз казался отсутствующим, но на щеках играл свежий румянец, а рыжеватые до плеч волосы были только что высушены. От нее исходил легкий аромат присыпки Джонсонс беби. Его взгляд скользнул по стройной фигурке, задержался на белой блузке с едва различимым под ней бюстгальтером, на юбке до колен цвета хаки и, наконец, на ее ногах… ногах Сьюзан Флетчер. Трудно поверить, что такие ножки носят 170 баллов IQ. Охранник покачал головой.
