Modelização espacial de territorialidades no estado do Pará : entre a Amazônia dos rios e das estradas

Abstract : Considering the multidimensionality inherent to the concept of territoriality and, consequently, of the territory, different analyzes were conducted aiming to modeling their processes. Was chosed a thesis structure based in vertices composed by different axes. In the vertex «classification» was conduzed studies based on the last 25 year data of value chains in the Pará state, seeking to infer about the horizontal and vertical dimension of geographical clusters, as well the co-occurrence of arregements of these groups and their configuration. The vertex «expression and properties» sought to qualify informations of deforestation and land use land cover dynamics targeting plans of regional development. While the vertex «vulnerability» took as indicator the burning, searching establish the territorial expression and latents trajectories to this landscape marker, that way a analitical protocol was proposed. The six axes of all vertices have constituted by independent articles, but with high concatenation. In all the cases was taked as reference free and universally acess data bases. In general, its concluded that the use of value chains, since considered their diachrony, was efficient in the inference of territoriality processus, even in the moment we can talk about territorials ‘domaines’ or ‘linkages’. Configurations of value chains (forest frontier, post-pionner front, «várzeas», co-arrangements and isolated chains) indicate that the pioneer front theory, released by Pierre Monbeig, as still adequated to explain the territorialization process in the region. The graphical modeling by means of «chorémes» demonstrated to be a useful tool in studies of this nature. The application of classifications and their refinement was efficient to the emergence of properties tha can be applied in studies of territorial planning and regional development. In the case of Pará state the territorial markers, post-deforestation are the secundary vegetation and pasture, in the most contrasting form of qualification: clean pasture and demanding recovery pasture. Given the territorial expression of vulnerability to burning zones, we have a new approach to landscape ecology studies, as well to the definition of patterns of land use/cover associated to other metrics and different conditions of regional development, as was the case of the frontiers evaluated. The application of modeling in the regional Geography demonstrated the possibility of new front of action in this approach.
