Soil erosion is the denudation or wearing away of the upper layer of soil. ... comprising approximately ten percent of that country's land area, ...
Splash erosion is generally seen as the first and least severe stage in the soil erosion process, which is followed by sheet erosion, then rill erosion and finally gully erosion (the most severe of the four). [10]: 60–61 [13] In splash erosion, the impact of a falling raindrop creates a small crater in the soil, [14] ejecting soil particles. [4]
Soil erosion is the main factor for soil degradation and is due to several mechanisms: water erosion, wind erosion, chemical degradation and physical degradation. Erosion can be influenced by human activity. For example, roads which increase impermeable surfaces lead to streaming and ground loss.
Potato field with soil erosion. In addition to the usual types of land degradation that have been known for centuries (water, wind and mechanical erosion, physical, chemical and biological degradation), four other types have emerged in the last 50 years: [11] pollution, often chemical, due to agricultural, industrial, mining or commercial ...
where R is the rainfall erosivity factor, K is the soil erodibility, [3] [4] L and S are topographic factors representing length and slope, and C and P are cropping management factors. Other factors such as the stone content (referred as stoniness), which acts as protection against soil erosion, are very significant in Mediterranean countries.
Deforestation in the country has also been associated with floods, soil erosion, deaths, and damage to property. [ 65 ] To combat deforestation, the Philippine government has made efforts to preserve and restore forests through reforestation projects such as the National Greening Program.
Members of the CCC, for example, developed state parks throughout the country and planted billions of trees in the plains to protect farms from wind erosion and another Dust Bowl.
Impact of gully erosion. The Nigerian gully erosion crisis has been underway since before 1980. It is an ecological, environmental, economic, and humanitarian disaster resulting in land degradation, as well as the loss of lives and properties worth millions of dollars. The estimated number of gullies in the country is at 3,000. [1]
