Estudo comparativo do uso da terra em unidades de produção familiar no Nordeste Paraense

Abstract

The historical context of territorial formation of the Paraense Northeast, is related with the several occupation periods that the Amazonian area suffered, from the origins of the colonization, going by the migratory flows, starting from the decade of 1950, until his/her current configuration. The Paraense Northeast is composed by Salgado's microrregiões, Bragantina, Cametá, Guamá and Tomé-Açu, occupying about 135 thousand squared kilometers, in other words, 10,6% of the state surface, including 49 municipal districts, possessing 1,8 million inhabitants, 27% of the state population. After almost a century of use the virgin forest areas are part of the past. The pattern of use of the earth bases on the handling of portions of secondary forest, in rotation with annual cultures and the implantation of perennial cultures and of pastures. In this context this work aimed at to understand the dynamics of the use of the earth in units of family production, for like this to subsidize alternatives for the planning of the properties. The research was accomplished in thirty three units, disposed in the municipal districts of Bragança (it presents an older occupation, with different occupation reports and use of the earth, approximately 300 years), Capitão Poço (it represents an occupation and use middlemen, 60 years) and Garrafão do Norte (with a process of more recent occupation about 20 years). the methodology based on the direct observation, in the application of questionnaires, semi-structured interviews, photographic registrations, elaboration of mental maps and use of the System of Geographical Information, for construction of thematic maps and analysis of the satellite images. It can be observed that the use pattern if it doesn't differentiate in the three areas, because it is not the atmosphere only that it will influence in the established practices, but each farmer's culture, in other words, his/her cultural load that it is printed on the territory. It was verified that the landscape of a property will be more or less fragmented in function of the number of people that you/they make use of her. The secondary vegetation is an important element in this dynamics, because his/her presence or absence will contribute more or less to a property to be resilient the pressures of markets, in other words, the existence of this forest resource, together with other productive systems, they allow that property to have a variety of products to be made available in the sphere of the family and to the market. It is like this necessary that strategies of planning of the property are elaborated, to guarantee the social and environmental sustainability.
