Implicações socioambientais causadas pelo processo de ocupação da região oeste do estado do Paraná entre as décadas de 1940 e 1980

Abstract

Whereas the socioenvironmental consequences vary according to occupational characteristics of the geographic space and historical time, this dissertation aims to analyze the socioenvironmental implications occurred in Western Paraná between the 1940s and 1980. The study was conducted based on a bibliographic review and analysis of data from the Brazilian Institute of Geography and Statistics (IBGE) that contributed for the preparation of charts and tables that are considered important to the analysis and discussion of the results. Grounded in literature was found that: a) the process of productive occupation of the West Region of Paraná with participation of Government, colonizers companies and migrants from several Brazilian states, especially South and Southeast contributed, directly and indirectly, to trigger socioenvironmental implications in different historical periods in the region; b) the period from 1940 to 1960 was marked by the activity of the colonizing companies that marketed the lands of the Mesoregion contributing to the problems of land conflicts and deforestation; c) the period from 1960 to 1980, marked by innovation in production techniques contributed to the practice of monoculture production, the expulsion of farmers and rural workers of the field, the intensification of deforestation and soil degradation, and further, the rivers pollution. The review of the literature and of the data from the IBGE enabled to consider that: a) even with the acting of colonizing companies in the process of the West Mesoregion occupation of the State of Paraná occurred the conflicts for land possession and the migration of people from the states not southerners, not reflecting the organization desired by the companies; b) there was intense changes in the natural characteristics of the West of Paraná, especially from 1960 with the acceleration of the production mechanization, the deployment of monoculture and the use of pesticides and chemical fertilization
