Agroforestry is one of the sustainable approaches to land-use management where both agriculture and forestry combine into an integrated production system to get maximum benefits (Kidd and Pimentel, 1992; Nair, 1998). As per ICRAF (International Centre for Research in Agroforestry, now World Agroforestry Centre), ‘‘agroforestry is a deliberate integration of woody components with agricultural and pastoral operations on the same piece of land either in a spatial or temporal sequence in such a way that both ecological and economic interactions occur between them.’’.
