1.0 INTRODUCTION TO AGRO FORESTRY
Agroforestry is the addition of trees and shrubs to the farming system in the form of interspaced trees, borders or shelterbelts.
The deliberate growing of woody perennials on the same unit of land as agricultural crops and/or animals, either in some form of spatial mixture or sequence.
Agroforestry is the intentional combining of agriculture and working trees to create sustainable farming systems.
ICRAF defies: 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 economic interactions between the different components (Lundgren and Raintree, 1982).
Involves two or more species of plants (or animals), at least one is a woody perennial;
Always has two or more outputs;
The cycle of an AF system is always more than one year
More complex than a mono-cropping system (ecological and economically)
Agro forestry land use is the deliberate inter or sequential cropping of woody and non- woody plant components(sometimes with animals) inorder to generate multiple product or services
Agro forestry is a collective name for land use system and technologies where woody perennials (trees, shrubs, palm, bamboo etc.) are deliberately grown on the same land management unit as an agricultural crops and/or animals either in a spatial mixture or in temporal sequence. There must be significant ecological and economical interactions between the woody and non-woody components.
1.2 Characteristics of Agro forestry
Multiple plant components, at least one of which must be woody perennial components of the system, either ecological and/or economical.
A high level of interaction (economic and biophysical) between the woody and non-woody...
