The Soil Erosion Site brings together reliable information on soil erosion from a wide range of disciplines and sources. It aims to be the definitive internet source for those wishing to find out more about soil loss and soil conservation. Dr David Favis-Mortlock, April 2017 Although there are many reasons for soil erosion, we’ll be only focussing on the erosion caused due to livestock farming and deforestation, equivalent to 55% of total erosion [3]. Since 80% of the agricultural land on the planet is used to produce crops for animal feed or for grazing animals, meat and dairy production contribute significantly to soil erosion and associated problems Soil Erosion - About the Data. Estimates presented here are based upon the latest information from the National Resources Inventory (NRI). The NRI is a longitudinal sample survey based upon scientific statistical principles and procedures. Soil erosion by water occurs when bare-sloped soil surface is exposed to rainfall, and the rainfall intensity exceeds the rate of soil intake, or infiltration rate, leading to soil-surface runoff.

How Soil Conservation | Soil Erosion | Methods Of Soil Conservation | Afforestation | Conserve Soil | What Is Soil Conservation | Steps For Soil Conservation 1 dag sedan · Additional soil conservation measures are needed, Fulajtar said, suggesting three promising approaches: no-tillage land management to reduce soil erosion caused by rainfall, while increasing the amount of water that infiltrates into the soil; switching to crops with higher soil conserving efficiency, for example from cassava, sorghum, peas and beans to wheat or other densely seeded crops; and Soil erosion occurs when soil is removed through the action of wind and water at a greater rate than it is formed SOIL The soil covering the surface of the earth has taken millions of years to form and we must learn to respect it. Soil is formed at a rate of only 1 cm every 100 2018-08-04 · Degraded soil diminishes food production and leads to soil erosion, which in turn contributes to desertification. This is particularly worrisome since, according to the UN's Food and Agriculture Organization, some 83% of sub-Saharan African people depend on the land for their livelihood, and food production in Africa will have to increase almost 100% by 2050 to keep up with population demands. Soil erosion is the process of removal or detachment of soil particles from the parent body and transportation of such particles by wind and/or water. Soil erosion is caused by several erosive agents like water, air, snow, plants, animal and humans.
