SOIL CONSERVATION
WHAT IS SOIL CONSERVATION?
Soil conservation focuses on keeping soils healthy
through a combination of practices and techniques.
Individuals committed to soil conservation help ensure
that soil is fertile and productive, and protect it from
erosion and deterioration.

THREATS TO SOIL CONSERVATION
The primary threats to soil conservation are climate
change and traditional farming practices, according to
the United Nations. Traditional farming practices
include the overuse of harmful pesticides that
contaminate soils, slash-and-burn methods, and land
overuse.

CHEMICAL CONTAMINATION
The use of pesticides can contaminate the soil, as well
as nearby vegetation and water sources, with harmful
chemicals. In addition to contamination, chemicals
used on crops can be toxic to important beneficial
insects, such as bees, as well as fish and bird
populations.

SLASH AND BURN
Slash-and-burn farming is the practice of burning and
clearing forests to make way for farmland. This
method kills plant species and displaces wildlife from
their natural habitats.

LAND OVERUSE
Overuse of land can limit soil’s ability to play its part
in the global climate cycle. For example, overcutting
forests and woodlands for timber and overgrazing
pastures can far outpace the natural regrowth of
vegetation, subjecting soil to increased exposure to
erosion.

SOIL CONSERVATION IS IMPORTANT FOR SUSTAINABILITY
For those working in sustainability, an understanding
of soil’s role can create opportunities to develop new
solutions and promote stewardship of our
environment.

PROVIDES FOOD AND SHELTER
Soil-producing vegetation provides nourishment to all
types of animals and offers protection from the
elements.
