Transformações econômicas e a mobilidade espacial da população na mesorregião norte de Mato Grosso de 1986 a 2010

Abstract

The migratory process is a social construction and represents a phenomenon that can be understood as the cause and effect of the transformations experienced by societies. Such transformations consist in the mechanisms which dive the social evolutionary process and they result from changes in the economic and social structures and the individual choices taken by each economic agent socially organized. Therefore, when considering that the populations move motivated by or in response to a given stimulus, it is admitted that their displacement promotes not only social changes, but they produce economic and environmental implications in a certain place with important reflexes on the regional development. In this perspective, the main objective of this study was to analyze the relationship between demographic dynamics and the economic transformations of the northern mesoregion of Mato Grosso State, considering its historical and institutional relationship with agricultural border occupation movements. Specifically, it was sought to identify the direction and volume of migratory flows which contributed to the demographic and economic formation of the mesoregion analyzed under the interstate, intrastate and intraregional spheres; to analyze the contribution of migratory movements on the spatial organization of population densities that form the north of the state, evaluating their effects on the mesoregion's attractiveness and identifying the main explanatory factors of spatial mobility and its relation with the productive transformations of the mesoregion. Using a descriptive methodological framework, based on demographic indicators and regional analysis, it was possible to identify the main elements that characterized the migratory dynamics of Mato Grosso state s northern mesoregion. The results showed a very heterogeneous scenario, with features of each Demographic Census analyzed, according to the level of aggregation adopted. At the interstate level, it was possible to evidence the relevance of the northern mesoregion in the state demographic context, marked by the alteration of the main destination areas, which were no longer represented by the extractive regions, giving place to the predominantly agricultural and agroindustrial areas, reflecting the changes in the state economic conjuncture. As for intrastate migration, it was shown that over the periods, the main migratory flow came from the mid-south mesoregion of the state, followed by the southwest, southeast and northeast regions of the state and indicated an alteration occurred since the 2000 Census when the north of Mato Grosso state, and in particular the micro region of Alto Teles Pires, presented the highest concentration of intrasessional flows, to the detriment of the central-south mesoregion, which until then comprised the most important region in terms of intra-state migration.Regarding the intraregional migration, the micro regions which concentrated the greater migratory flows were Colider, Sinop, and Alta Floresta, however, the 2000 Census demonstrated that Alto Teles Pires micro region emerged in the migratory scenario and, from that period on, it has become the intraregional immigrants main destination.
