Resumo: | In the state of Minas Gerais, water abstraction below 1.0 L/s does not need to be authorized, but requires a registration of insignificant use. The hypothesis of this work is that these registrations for water abstraction issued in series along small stretches of a watercourse can substantially alter its water availability, and consequently cause environmental impacts, as well as lead to conflicts over water use. In this sense, the objective was to analyze the Water Resources State Policy of Minas Gerais, regarding the insignificant uses, contributing to the knowledge of the interference of these uses in the surface water availability of the hydrographic basin of the Suaçuí river - MG. For this, the list of surface water users in the study area was obtained from the Instituto Mineiro de Gestão das Águas. The water availability of the basin was calculated by stretches of watercourses, analyzing the interference of insignificant uses. Analyzing all the stretches in which insignificant uses are present, 555 were found to be unavailable, most of these stretches being of small extension, located in headwater regions of the study area, and also stretches where there are two or more catchments considered insignificant, or in consecutive stretches. This result suggests that the way that insignificant use registrations are granted should be revised, taking as a basis the water availability of the stretch to be demanded, and not only limited by a maximum flow. |

La hipótesis de este trabajo es que estos registros de extracción de agua emitidos en serie a lo largo de pequeños tramos de un curso de agua pueden alterar sustancialmente su disponibilidad de agua y, en consecuencia, causar impactos ambientales. En este sentido, el objetivo fue analizar la Política Estatal de Recursos Hídricos de MG, en lo que respecta a los usos no significativos, contribuyendo al conocimiento de la interferencia de estos usos sobre la disponibilidad de agua superficial de la cuenca hidrográfica del río Suaçuí - MG. Para ello, se obtuvo del Instituto Mineiro de Gestão das Águas la lista de usuarios de aguas superficiales en el área de estudio. La disponibilidad hídrica de la cuenca se calculó por tramos de cursos de agua, analizando la interferencia de los usos no significativos. Analizando todos los tramos en los que están presentes los aprovechamientos insignificantes, se ha comprobado que 555 se encuentran en situación de indisponibilidad, siendo la mayoría de estos tramos de pequeña extensión, situados en regiones de cabecera de la zona de estudio, y también tramos en los que hay dos o más captaciones consideradas insignificantes, o en tramos consecutivos. Este resultado sugiere que se revise la forma de otorgar las inscripciones de uso insignificante, tomando como base la disponibilidad de agua del tramo a demandar, y no sólo limitada por un caudal máximo.No estado de Minas Gerais, captações inferiores a 1,0 L/s não precisam ser outorgadas, mas necessitam de um cadastro de uso insignificante. A hipótese deste trabalho é de que esses cadastros para captação de água emitidos em série ao longo de pequenos trechos de um curso de água podem alterar de forma substancial a disponibilidade hídrica do mesmo, e consequentemente, provocar impactos ambientais, bem como propiciar conflitos pelo uso da água. Nesse sentido, o objetivo foi analisar a Política Estadual de Recursos Hídricos de Minas Gerais, no que se refere aos usos insignificantes, contribuindo para o conhecimento das interferências destes usos na disponibilidade hídrica superficial da bacia hidrográfica do rio Suaçuí - MG. Para isso, foi obtida junto ao Instituto Mineiro de Gestão das Águas a relação dos usuários de captação de água superficial do local de estudo. Calculou-se a disponibilidade hídrica da bacia por trechos de cursos d’água, analisando as interferências dos usos insignificantes. Analisando todos os trechos nos quais os usos insignificantes estão presentes, foram constatados que 555 usuários se encontram em situação de indisponibilidade, sendo a maioria destes trechos de pequena extensão, localizados em regiões de cabeceira da área de estudo, e também trechos onde existem duas ou mais captações consideradas insignificantes, ou em trechos consecutivos. Este resultado sugere que a forma como são concedidos os cadastros de usos insignificantes deve ser revista, tomando como base a disponibilidade hídrica do trecho a ser demandado, e não apenas limitado por uma vazão máxima.Research, Society and Development2022-02-07info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/2598810.33448/rsd-v11i3.25988Research, Society and Development; Vol. 11 No. 3; e0311325988Research, Society and Development; Vol. 11 Núm. 3; e0311325988Research, Society and Development; v. 11 n. 3; e03113259882525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/25988/22932Copyright (c) 2022 Guilherme de Barros Moreira; James Lacerda Maia; João Paulo Oliveira Silva; Eliane Maria Vieirahttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessMoreira, Guilherme de Barros Maia, James Lacerda Silva, João Paulo Oliveira Vieira, Eliane Maria 2022-03-09T13:44:38Zoai:ojs.pkp.sfu.ca:article/25988Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:44:08.238183Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false |
