Being thus inside of this approach, the use of the agroflorestais systems also assigned in the half academics as SAF? s frequently is pointed as one of the viable options, when it questions strategies of sustainable use of the land in tropical regions of Brazil, especially in if treating to areas of the Amaznia. Although the increasing popularity that the agroflorestais systems come trying, in many regions, particularly in tropical areas, still exists innumerable questionings not answered, many of them, also with respect the basic questions on the functions that these systems can exert and the advantages and disadvantages in comparison to other systems of exploration of the land. Among others concepts, the agroflorestais systems can be understood as a corporate name for all the practical systems and of the land use, where the lenhosas perennial species deliberately are planted in the same unit of land handling with agricultural and/or animal cultivos, as much in space mixture or sequential weather, with significant ecological and economic interactions between the lenhosos and not lenhosos components (Lungren, 1987). This definition indicates the multifaceted nature of the agroflorestais systems, beyond what, it shows the diverse functions that are important in the handling of the land. For implementation of a system, the diagnosis of the reality becomes imperative where the same he will be inserted. In such a way, it must be analyzed the social characteristics of the local community (the educational level, nutricional state, age of the residents, division of work, etc.), the ecological characteristics (the ground, climate, biodiversity, topography, etc.), as well as the economic characteristics (market, flow of box, etc.).
The proper generation of technology must be based on the current production. Some interrogations must be raised: How it is the social structure? Which the potential of the ground? How behaves the market? Which the practical ones of culture? . It can be that at some times of the year it has man power availability or then that the periods of entresafra bring until hunger.
