Agroforestry is the deliberate incorporation of trees and other woody species of plants into other types of agricultural activities. By definition the use of woody species must result in the enhancement of either the biological productivity or the economic return of the system, or both. There are many types of agroforestry, which are usually defined by what type of agricultural activity is involved, but this can be a very broad definition and includes what we normally think of as agriculture (agroforestry), but also other combinations such as livestock production (sylvo-pastoral agroforestry) and even aquaculture (sylvo-aqua agroforestry). Even more complicated versions are possible such as agricultural systems that incorporate livestock, trees and aquaculture (sylvo-pastoral-aqua agroforestry).
