Técnicas Agrícolas, Preservação E Impactos Ambientais Na Região Oeste Do Paraná

The aim of this paper is to analyze the implications of technological change of Paraná agriculture and environmental impacts of these structural changes, choosing the backdrop of the western Paraná. The technological agricultural model introduced in Brazilian agriculture since the 1950, and (later 1970) in Paraná agricultural framework, has as one of its central features the exclusion of small producers, stimulating the production of high commercial price crops (commodities), which, by their nature, require extensive planting areas at the expense of food produced by most producers. It is noteworthy that the pressure of the industrial sector on the agricultural sector, strengthened after the process of industrialization and internationalization of capital, is significant. The methodology involved a literature review, listing the economic cycles that marked the occupation of the State of Paraná and the exploitation of natural resources, as well as the maintenance of environmental preservation areas, specifically the Iguaçu National Park, established in 1939 as a reserve Full Protection. The results allowed us to consider the character of dispersion of technological change in the state of Paraná agriculture, understanding that not all of its regions make technical and mechanized the same time.3630232
