Who is responsible for soil erosion

These productivity losses reduce the quantity and quality of the food we eat. A study based on the results of 40 soil associations reported that the effects of soil erosion on soil productivity were mostly the result of subsoil properties such as soil water availability, root growth or plow layer fertility — which impact yield results.

In the end, with an unfavorable subsoil, erosion is easier and yields and productivity are more greatly affected. Despite the fact human activities have accelerated soil erosion, there are ways of repairing the damage we have created.

From reforestation and windbreaks to stone walls or more sustainable agriculture techniques. Regenerative agriculture techniques have the potential to preserve and restore ecosystems and habitats and improve the quality and health of the soil. Windbreaks are linear plantings of shrubs and trees with the goal of improving crop production, protect the soil, people, and livestock.

According to FAO , windbreaks can reduce wind velocities for a distance approximately 15 times the height of the tallest trees. As a result, there is a lower rate of soil loss across large crop areas. According to Camera et.

According to FAO , reforestation helps reduce sedimentation rates in downstream valleys. According to this UN agency, reforestation on unstable land and around water regions such as rivers increases the water-retention capacity of land and improve water quality, both of which benefit food production. Moreover, according to a recent study published in Nature , reforestation also has a tremendous potential to help fight climate change as trees capture huge amounts of CO2.

Conservation tillage stands for as any form of tillage that minimizes the number of tillage passes. Conservation tillage techniques have the potential to reduce the vertical movements of soil. In this way, more crop residues are left on the soil surface reducing the exposure to water or wind erosion.

FAO, bringing attention to the fact that a lthough soils are essential for human well-being and the sustainability of life on the planet, they are threatened on all continents by natural erosion. The dirt beneath our feet is getting poorer and on many farms worldwide, there is less and less of it. Quote by Franklin D. Soil is lost rapidly but replaced over millennia and this represents one of the greatest global threats for agriculture.

Last Name. Soil Erosion Simple Definition Soil erosion is a gradual process of movement and transport of the upper layer of soil topsoil by different agents — particularly water, wind, and mass movement — causing its deterioration in the long term.

What Is Soil Erosion? Different Soil Erosion Causes Soil erosion is a complex process that depends on soil properties, ground slope, vegetation, and rainfall amount and intensity. According to Al-Kaisi from Iowa State University , there are 5 main types of natural soil erosion: 1 Sheet erosion by water; 2 Wind erosion; 3 Rill erosion — happens with heavy rains and usually creates smalls rills over hillsides; 4 Gully erosion — when water runoff removes soil along drainage lines 5 Ephemeral erosion that occurs in natural depressions.

The Main Causes And Impacts Of Soil Erosion The most effective way of minimizing erosion is to guarantee a permanent surface cover on the soil surface, such as trees, pasture, or meadow.

Deforestation for Agriculture Is One of the Top Causes of Soil Erosion The increasingly high demand of a growing population for commodities such as coffee , soybean, palm oil or wheat is clearing land for agriculture. Agrochemicals Cause Soil Erosion and Degradation The use of chemicals under the form of pesticides and fertilizers on often monocultural crops is a very usual way of helping farmers improve their yields.

The Importance of Soil, Especially Topsoil Soil is a very important resource that allows the production of food, fiber, or forages. If we are aware of the fact it takes about years to form 2. Among other problems is the wide use of ammonia fertilizers, massified by the Haber-Bosch method , with the primary goal of helping increase crop yields but with devastating consequences in marine ecosystems.

The academics from the Grantham Centre proposed a couple of solutions to fight soil loss and degradation. Among them are: 1 using biotechnology to wean plants off their dependence upon fertilizers; 2 including recycling nutrients from sewerage or 3 rotating crops with livestock areas to relieve pressure on arable land.

There are, nonetheless, other ways of protecting the soil. How to Prevent Soil Erosion Despite the fact human activities have accelerated soil erosion, there are ways of repairing the damage we have created. Deforestation 2. Overgrazing 3. Faulty Methods of Agriculture. Comments Dislike Bookmark. Human is responsible for soil erosion as follows : 1 due to cutting down trees the roots of trees that hold the soil together are destroyed hence the soil becomes loose and is easily eroded.

As we know that tress play a very important role in holding the soil and prevent in getting it erroded by wind, flood,etc. And men are constantly cutting down trees, thus leaving the land barren and open for soil erosion. Soil erosion is a natural phenomenon which is caused by excessive use of water flood and by wind. Farmer do use large quantities of pesticides this reduces the fertility and the human is responsible for this.

Man cuts down trees leaving the land barren. Wind, rain flowing over the area leads to soil to blow and causes soil erosion. Humans are responsible because for their own benefit they are cutting tress and building plants and buildings,. The roots of trees holds the soil and prevent it in getting eroded in rainy season.

If there would be no trees then how the soil will be held? Deforestation, overcropping,over grazing. Over grazing, over cropping, deforestation. Humans are constantly cutting down tress for their own benefits and comfort. Tree roots hold the soil together and prevents in getting it eroded due to natural causes like wind or flood. But if tress are cut then there would be no roots to hold the soil.

This is already happening in China, where the Grain-for-Green project in the Yellow River basin conserved soil and water and reduced carbon emissions. On the flip side, unchecked climate change can worsen erosion.

The risk of erosion will become even higher in the future due to emissions-driven temperature changes, with resulting decreases in agricultural production, land value and human health. Similar erosion-related floods have occurred in many other countries, such as Colombia , India , the Philippines and Democratic Republic of the Congo. Soil erosion is not only an environmental issue; it also causes huge losses to the economy. The U. This value includes lost productivity, along with sedimentation and water pollution.

Terraced farming needs to be implemented to make hillside agriculture manageable. Terraces prevent erosion and allow more water to flow to crops.

In addition, hillside farm fields need full crop cover to help keep the soil in place. This can be accomplished by intercropping, which means growing two crops together in the same field, such as planting rows of maize or soybean between rows of oil palm trees.

For smallholders, agroforestry systems where a diverse set of crops, including trees, are grown together can be effective. Access to manure improves the organic matter of the soil, which inhibits erosion. Finally, alternating deep-rooted and shallow-rooted crops improves soil structure and reduces erosion at the same time. Although the science of sustainable land management has been gaining support, the socio-economic context often makes implementation difficult.

Sustainable land practices need to be financially viable for farmers. Governments and banks must help farmers get access to credit and support in implementing erosion prevention. This is not only a good deal for the farmer, but for the whole community. The key to managing and reducing soil erosion is to rehabilitate already-damaged land , stop further degradation and put erosion-preventative measures at the core of land management policy.
