Proteção ambiental : uma análise da prática agropecuária das queimadas

Abstract

This study has as main objective to analyze the behavior of fires, agricultural practice still widely used in Brazil. The use of fire, though very contested within the scientific community by environmental groups and society in general, is a common reality in several Brazilian states. In the South, specifically in Santa Catarina and Rio Grande do Sul, this activity has been widespread, mainly due to the steep topography and the existence of many rocks, which make the management of the pasture accumulated during the late winter very difficult. The reasons for the use of burning as a management strategy would be related to eliminate the excess of "dry" material created by the cold of winter, according to the producers, it would damage the regrowth in the spring, because the animals do not consume the old dry grass. Other issues raised were related to the degree of infestation of undesirable species in burned and unburned areas, as well as speed and quality of forage regrowth after burning. Therefore, faced with this situation, the purpose of this study is discuss and analyze the main effects of the burnings, considering the advantages, disadvantages, and especially the damage caused by frequent and continuous use of fire as a management tool and cleaning. At the same time, it aims to address the issue of environmental protection according to this practice, examining the damage caused to the environment and human health, under the legal approach, especially the provisions of the Constitution and constitutional legislation, which are the prime objectives for the full protection environment, such as legal and common use of all, against any and all damages which may be caused.
