Soil erosion is the displacement of the upper soil layer caused by natural agents such as water, air, and human activities, particularly through farming and land clearing. It leads to decreased fertility, increased pollution, and can cause flooding due to degraded lands. Preventative methods include replanting trees, using protective materials in vulnerable areas, and stopping illegal logging and mining.

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 -human
- 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 clearing leave soil
vulnerable to 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.

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

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

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

12. Road destruction

13. Farm destruction

14. 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.

15. Can Soil Erosion be
Prevented?

16. 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.

17. 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.
