Promoting agroforestry is one option many perceive
as a major opportunity to deal with problems related
to land-use and CO2-induced global warming. In this
paper agroforestry is defined as any land-use system
that involves the deliberate retention, introduction or
mixture of trees or other woody perennials with agricultural
crops, pastures and/or livestock to exploit the
ecological and economic interactions of the different components (Lundgren, 1982; Nair, 1993; Young,
1997). Historical evidence showed that agroforestry
has been widely practised through the ages as a means
of achieving agricultural sustainability and slowing the
negative effects of agriculture such as soil degradation
and desertification.
