2.  One of the major
advantages of agroforestry
in terms of improving or
sustaining soil productivity
is through its effect on soil
conservation.
(Young, 1989).

3.  Soil erosion has, in all likelihood,
been a problem since time
immemorial.
Changing concepts and trends
(Nair and Young, 1989).

4.  A large number of scientific
publications that address soil
erosion and conservation were
published during the 1980s.
 Erosion is one of a number of
forms of soil degradation.
 The adverse effects of erosion
used to be expressed in terms of
reduction of crop yields and/or
loss of soil.
 The traditional "barrier approach"
to soil conservation
Soil productivity and protectión

5. A major feature of these
predictive models is that
they indicate very high
potential for reducing soil
erosion through
management, most
importantly by
providing effective land
cover.

6. Erosion control through
agroforestry in practice
Farmers throughout the
world have a long tradition
of using trees and shrubs
on their farmlands for soil
erosion control in a number
of ways. These include
both direct use of these
species for reducing erosion,
and their supplementary
use for stabilizing physical
structures that are created
specifically for erosion
control.
