Licenciamento ambiental e outorga do uso da água para instalação de um sistema de irrigação por aspersão tipo pivô central: um estudo de caso

Abstract

The practice of irrigation through the central pivot system has been increasing in the western border of Rio Grande do Sul due to the operational ease, the high adaptability to different soil conditions and topography, and climatic variability. The controlled presence of water in agricultural production, through the use of irrigation, allows the farmer to increase the number of crops, passing the cultivar in different seasons or seasons and having the possibility of harvests between the harvest. Research carried out in educational institutions may assist the rural producer in the decision making regarding the implantation and management of irrigation systems. In order to start irrigation equipment, such as the central pivot, environmental licensing is required for the irrigation activity, the reserve for water availability and the granting of water use. The implementation of an irrigation system at the Farroupilha Federal Institute Campus Alegrete is of extreme importance for the development of research in both the agricultural and zootechnical fields, since in this area grains and pastures will be planted. In this sense, this work has as main objective to carry out the documentary survey for the environmental licensing and granting of the use of the water for the installation of a system of irrigation Central Pivot, and as secondary objectives to realize the mapping of the area through the topographic survey and reconstitution of the existing dam project.
