According to Ojebor (1996), land erosion is the
removal of uppermost layer of the earth surface. This process is carried out by
agent of denudation e.g. water, wind, wave etc.

Erosion refers to the breaking up and wearing away of
exposed rock by moving water (rivers and waves) the wind moving ice (Bunnet and
Okunrotifa, 2004)

Thomas (2004), pointed out that the destructive
process of desertification, deforestation and soil erosion are continuing and
the situation is getting increasingly critical.

Carla (2008), states that soil erosion is a part of
the process of weathering and transport of solid (sediments, soil, rock and
other particles) in the natural environmental or other sources and deposits
them elsewhere. It usually occur due to transportation by wind water or ice, by
down-slope creep of soil and other materials under the force of gravity, or by
living organism such as burrowing animals in case of bioerosion. Erosion is a
natural process but has been increases by human land use especially
agriculture, deforestation and urban sprawl. Excessive erosion causes serious
problem such as receiving water sedimentation, ecosystem damage and outright
loss of soil.

Man due to his activities such as industrialization,
urbanization, deforestation/causing desertification and land erosion and other
activities on the land have polluted and degraded the environment.
