Sistemas de usos da terra situados no Estado do Pará.

Abstract

Thxs research identified 39 land use systems established in the Pará State, Brazil. Soon after, using the methodology òf the indicators, was described, classifíed and compared the land use systems. The results showed that for obtainmg of profits by the traditional timber exploitation, it is necessary extensive forest areas. However, the traditional timber exploitation presents negative social and ecological impacts. The logging with reduced impact method is a promising solution for the use of forest resources, even so it is still being tested in some areas of the State. The creation of oxen presents economic, social and ecological hmitations because the difficulty ofmaintenance of extensive gram areas. The cassava plantation is an immediate solution to supply the needs of small rural producers where the surplus is marketed for purchases of medicines, clothes, etc. The dendê plantation is a system addressed for great producers due, that requests an orgamzed structure. It is necessary to test the results ofthat study assuring, for example, that cassava plantation be only to supply the needs of the producer or that the traditional timber exploitation be the solution for ali the actors that want to do use ofthe forest products. In particular, to look for the sustainable, the systems can be selected, defíned in agreement with the objectives and established in small areas of a lot in the intensive form. Finally, the continuity of new studies is stood out with other system forms, using groups of indicators, that facilitate to gather several information to restmcture the land use system established in the area.
