Ecology of Soil Erosion in Ecosystems

  title={Ecology of Soil Erosion in Ecosystems},
  author={David Pimentel and Nadia Kounang},
ABSTRACT Each year, about 75 billion tons of soil are eroded from the world's terrestrial ecosystems. Most agricultural land in the world is losing soil at rates ranging from 13 tons/ha/year to 40 tons/ha/year. Because soil is formed very slowly, this means that soil is being lost 13–40 times faster than the rate of renewal and sustainability. Rain and wind energy are the two prime causes of erosion from tilled or bare land. Erosion occurs when the soil lacks protective vegetative cover. Soil… 
Soil-erosion and runoff prevention by plant covers. A review
– Soil erosion is a critical environmental problem throughout the world’s terrestrial ecosystems. Erosion inflicts multiple, serious damages in managed ecosystems such as crops, pastures, or forests
Soil-erosion and runoff prevention by plant covers. A review
This review article highlights three majors topics: the impact of erosion of soil productivity with particular focus on climate and soil erosion; soil seal and crust development; and C losses from soils.
Soil Erosion: A Food and Environmental Threat
Soil erosion is one of the most serious environmental and public health problems facing human society. Humans obtain more than 99.7% of their food (calories) from the land and less than 0.3% from the
Soil Erosion Threatens Food Production
Since humans worldwide obtain more than 99.7% of their food (calories) from the land and less than 0.3% from the oceans and aquatic ecosystems, preserving cropland and maintaining soil fertility

Water erosion is a process that has a strong negative impact on soil and soil fertility. In addition to the large losses of fertile soil, as a result of the effects of water erosion, significant
Controlling Soil Erosion Using No-Till Farming Systems
Soil erosion is a natural phenomenon that has been thrown off balance by human activity and particularly by agriculture. It is associated with severe environmental impacts, high economic costs,
A review on soil erosion conservation measures in Nepal
Soil erosion is one of the most serious environmental problems in Nepal. It has resulted to the loss of agricultural crops and top soil every year. Different soil conservation techniques are being
Global vulnerability of soil ecosystems to erosion
A global and temporally explicit assessment of soil erosion risk according to recent dynamics of rainfall and vegetation cover change is presented to identify vulnerable areas for soils and soil biodiversity.


World Soil Erosion and Conservation
Land degradation from soil erosion has been considered by many to be a problem of significant proportion, affecting some 30 50% of the earth's land surface. At the time of the first publication of
Environmental and Economic Costs of Soil Erosion and Conservation Benefits
With the addition of a quarter of a million people each day, the world population's food demand is increasing at a time when per capita food productivity is beginning to decline.
Soil Erosion
Soil erosion is the process by which soil is moved by wind, water, or other natural actions. Vegetation and other coverings help prevent soil erosion. When the soil is exposed, it is vulnerable to
Soil Erosion and Conservation
Soil erosion is one of the most serious environmental concerns worldwide. Continued soil erosion can result in degraded soil quality and ultimately reduced crop yields and profitability. In addition,
Soil erosion and crop productivity
Soil is a natural resource of great importance in agriculture, especially because it provides crops with water, nutrients and rooting space. Nevertheless, soil degradation is accelerating, with
Erosion and soil productivity in Africa
ASIA probably has suffered more from human-induced soil erosion than any other continent. As one of the first to describe the impacts of erosion on early civilizations, Walter Lowermilk noted the
The influence of management on soil loss and yield of wheat in Chernozemic and Luvisolic soils
The effects of management practices on erosion and crop productivity for different agro-ecosystems in Canada are largely unknown. A study was conducted to examine the effects of management on soil
Desert Ecosystems: Their Resources in Space and Time
The dynamics of desert ecosystems control levels of resources that are essential to the survival of desert biotas. Because precipitation is both low and relatively unpredictable in arid regions, the
