Agroforestry is a collective name for land-use systems and technologies where woody perennials (trees, shrubs, palms, bamboos, etc.) are deliberately used on the same land-management units as agricultural crops and/or animals, in some form of spatial arrangement or temporal sequence. In agroforestry systems there are both ecological and economical interactions between the different components (Lundgren and Raintree, 1982). Agroforestry acts against erosion, provides mulch to cover the soil, feed to the animals and fuel wood, enhance soil fertility and can increase crops productivity.
