Human activities and soil erosion

Mar 12,  · Aside from desertification, there is no doubt that human activities are a major cause of soil erosion in general.

How do human activities cause soil erosion? - Amit Sengupta

Soil erosion is defined as the wearing away of topsoil. Soil is naturally created when small pieces of weathered rocks and minerals mix with organic materials from decaying plants and animals. It takes many years to create soil. However, the soil that is created faces constant pressure of natural and human activities. Human activities are one of the major reason behind soil erosion. When we say human activities, the following activities fall under this category When a farmer plows a field to sow a crop.

They leave the soil bare and exposed to some natural elements like rain, wind, sun rays. These are called exogenic forces, because they have the power to cause enough damage to the soil.

Wind can carry the loose soil from one place to another with force. Rain can sweep into the open bare soil and wash away the soil quickly. Deforestation:- Wood is an essential natural resource for human beings. It is human activities and soil erosion to produce paper, paper products, fabrics and many consumer goods.

These products comes from tree harvesting. But tree harvesting is an underestimated word, instead complete annihilation of forest ecosystem takes place. Deforestation causes some of the worst soil erosion. The root structure of trees hold the soil in one place. The leaves and canopy of big, tall trees protects the soil from wind and rain. In the absence of trees, it can lead human activities and soil erosion heavy erosion of topsoil. Construction activities:- Construction of roads and buildings, human activities and soil erosion, excavation, mining has resulted in huge amount of soil erosion.

This makes the soil expose to natural forces of wind and rain. Construction is also synonymous to urbanization. On one hand, development of cities and mega-cities is seeing as a progressive sign of a nation, and on the other hand rapid urbanization results human activities and soil erosion soil erosion and loss of natural habitat. Overgrazing:- There is direct connection between overgrazing and increase in soil erosion.

Dairy farmers allow animals like cattle, goat, sheep to graze in open area for a longer duration. Because of which, overgrazing is a common phenomena.

When animals graze and area for a longer duration without giving the grasses enough time to grow back.

It makes the topsoil expose to the forces of wind and rain and that leads to increase in soil erosion. Overgrazing can cause damage to the quality of land.

Over-cropping:- Over-cropping leads to depletion of nutrient from the topsoil. It makes the land prone to desertification. In other words, a land can look like a desert which will further accelerate soil erosion.

Over-cropping leads to soil exhaustion and makes the soil vulnerable to erosion. Your email address will not be published. Save my name, human activities and soil erosion, email, and website in this browser for the next time I comment.
