Meaning of soil erosion, agents and the cause and effects.

1. Soil Erosion

2. Displacement of the upper layer of soil; it is a form of soil degradation. This natural process is caused by the dynamic activity of erosive agents, that is; - water - water - air -humans - ice - plants - snow - animals

4. What Causes Erosion?

5.  occurs primarily when dirt is left exposed to strong winds, hard rains, and flowing water. In some cases, human activities, especially farming and land clea ring leave soil vulnerable to erosion . Soil erosion

6. Human Activities Land clearing and illegal logging may caused the soil unfertile. No roots can hold the soil so that it may easily erode. Illegal logging Land clearing

7. Dry land During rainy days, soil may easily get eroded because of this cause. The cracks will serve as the passages of water. While water flows, it may excavate the soils.

8. Illegal Mining

9. No discipline community may also cause erosion. For instance, improper disposal of garbage. “What we sow, we will reap.”

10. Community Vanishes Improper waste disposal may cause flash flood that leads to erosion.

11. Road destruction

12. Farm destruction

13. The effects of soil erosion go beyond the loss of fertile land . It has led to increased pollution and sedimentation in streams and rivers. Clogging these waterways and causing declines in fish and other species . And degraded lands are also less able to hold onto water, which can worsen flooding.

14. Can Soil Erosion be Prevented?

15. Methods to Prevent Soil Erosion Plantation of trees and plants . Placing crushed stone, woodchips and other similar materials in heavily used areas where vegetation is hard to establish and maintain. Stop illegal logging.

16. Methods to Prevent Soil Erosion Stop illegal mining and quarrying. Do less in clearing lands without purpose. Know the effects of doing improper things to discourage one’s self. Minimize cutting of trees. If done, plant another tree as replacement .
