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 differ-
