1 Introduction Soil erosion is a critical environmental problem in many countries and affects an area of 3.6 9 106 km2 in China; about 37% of its land area (Ni et al.2008).
The effects of soil erosion can be felt on-site, meaning at the site of soil disruption, because soil quality is reduced. The effects can also be felt off-site, meaning the location where the
Goals / Objectives 1. Quantify rain- and irrigation-induced soil erosion and nutrient movements in the selected experimental sites of the Apalachicola Basin (North Florida and South Georgia) that represent variations in soil, crop and managements.
a bad effect on economic development of this region.Soil erosion only occurrs in given environment backgrounds involving vegetation index,soil utility,slope,etc.But different environmental factor has
This paper reviews several recent studies conducted by the authors that address the potential effects of climate change on soil erosion rates. The results show cause for concern. Rainfall erosivity levels may be on the rise across much of the United States. Where rainfall amounts increase, erosion and runoff will increase at an even greater rate: the ratio of erosion increase to annual
1 Soil Erosion Causes and Effects: Introduction Soil erosion is one form of soil degradation along with soil compaction, low organic matter, loss
ABSTRACT Soil erosion is affecting global food security. Though it is a natural process, its rate has increased significantly during the last century mainly by human activity.
Soil erosion is one of the biggest global environmental problems resulting in both on-site and off-site effects. The economic implication of soil erosion is more serious in developing countries because of lack of capacity to cope with it and also to replace lost nutrients.
Erosion is dependent on the amount, duration, intensity and frequency of rainfall. By the action of dashing rain drops on soil, soil granules are loosened, detached and separated into fine particles.
Soil erosion effects on soil productivity: A By the National Soil Erosion-Soil Productivity Research Planning Committee, Science and Education
Soil erosion and the effects of soil erosion on crop productivity have become emotional issues and have attracted the attention of agriculturists, environmentalists, and the public in general. In spite of heavy investments in research and development, the global rates of accelerated erosion are now presumbly higher than ever before. However

Slope Shape Effects on Erosion: A Laboratory Study D. H. Rieke-Zapp and M. A. Nearing* ABSTRACT the form of DEMs is more explicit and detailed than Data on soil erosion at the slope scale is essentially limited to information often used in the past. However, to fully experiments on uniform slopes. The objective of this research was to take advantage of information provided by the DEMs, …
Soil erosion and the effects of soil erosion on crop productivity have become emotional issues and have attracted the attention of agriculturists, environmentalists, and the public in general.
The effects of erosion impact two places: on-site (where the soil has become detached), and off-site (where the eroded soil goes). Subsequent harm results in damage to plants, animals,
Past soil erosion for the African continent as a whole has caused an average annual crop yield decline of 8.2% and 6.2% for sub-Saharan Africa and that if higher soil erosion rates continue unabated, average annual crop yield declines of 16.5% and 14.5% for sub-Saharan Africa may be possible.

A.N. Desai, Ravi Kant, in Geotextiles, 2016. Mechanism of soil erosion. Soil erosion is the process of detachment and transportation of soil by wind or surface water, because of insufficient or improper vegetative cover.

Water erosion on watershed slopes is a complex process that brings together the impact of raindrops, removal of slope deposits, and transportation of loose material by overland flow.

under the effect of water, air and living organisms requires time. The soil formation rate usually does not exceed 0.1 mm of soil per year and to form fertile soil suitable for agriculture often requires several hundred or even thousands of years. In contrast the loss of soil can be a quick process, especially if barren soil is exposed to erosion by water or wind. Combating soil erosion
EFFECTS OF SOIL EROSION ON AGRICULTURAL PRODUCTIVITY IN SEMI-ARID REGIONS : THE CASE OF LOWER CHAMBAL VALLEY Introduction Soil erosion is a world-wide challenge for sustainability of agriculture especially in tropical region. It is the process of detachment and transport of soil particles. Erosion can decrease rooting depth, soil fertility, organic matter in the soil and plant …
The erosion coefficient, which indicates the erosion intensity in the catchment and the total annual volume of the detached soil, which indicates the overall erosion sediment production on an annual basis, were derived in a form of maps for the Dubračina catchment.
Possible effects of wind erosion soil productivity LEON LYLES ABSTRACT-I propose a procedure for evaluating the efects of wind erosion on soil loss and subsequent crop yields.
This study is a review of the effects of soil erosion on the water sources in the Northeastern Enugu State, Nigeria. Since, water is viewed as an indispensable natural resource for all facets of human development and well being. Its utilities are gradually being destroyed by soil erosion, induced siltation, eutrophication, pollution, water related diseases transmission and channel abrasion
