Rural people have been discovered to have a wealth of
indigenous knowledge and have incorporated trees in
production systems in areas where they lived for a very
long period of time (Evans and Alexander, 2004).
Agroforestry has both protective and social-economic
benefit. Kang (1993) reported that besides direct
agricultural benefit, trees exhibit social - economic
values. The benefit of the tree components derived by
farmers from agroforestry was evaluated from a socialeconomic
and ecological perspective (Anderson and
Sinclair, 1993). The social - economic benefits of
agroforestry can be evaluated in terms of productivity,
stability and sustainability.
