2019–2022 Water Level Drop in the Paraná River : Causes and Effects

The Paraná River basin has approximately 2,700,000 km², while its main affluent, the Paraguay River, involves areas of Bolivia, Paraguay, Brazil and Argentina. Simply put, the flow of Paraná River originates mainly from rain falling on the tributary basins of the Alto Paraná (Brazil), the Iguazú Riv...

description The Paraná River basin has approximately 2,700,000 km², while its main affluent, the Paraguay River, involves areas of Bolivia, Paraguay, Brazil and Argentina. Simply put, the flow of Paraná River originates mainly from rain falling on the tributary basins of the Alto Paraná (Brazil), the Iguazú River (Brazil and Argentina) and the Paraguay River (Paraguay, Argentina and Bolivia). River regime has always been characterized by cycles, alternating water level rises and drops (or low flows), with different degrees of severity and duration.As for the extraordinary drop occurred in the 2019–2022 period, among its causes one may mentioned variability and climate change; alterations in runoff conditions due to changes in land use (deforestation, intensive agricultural practices involving monocultures, elimination of natural floodplains, fires, unplanned and illegal channeling); etc.This kind of extraordinary event has an impact on numerous aspects related to the river environment, for example, alterations in wetland ecosystem services (flora, fauna, water quality, soil alterations). The drop also affects infrastructure works, such as water supply intakes, and inland waterway transport, among others.This special issue of the Journal presents and disseminates works focused on the causes and effects of the extraordinary drop of the Paraná River water level during the 2019–2022 period, with contributions from different disciplines concerned with this issue.The content of this section may be of interest to researchers, professors, experts, students and professionals connected to the topic.The editorial board of the Journal wishes to thank the professionals involved for their contributions to this issue.

La cuenca del río Paraná tiene una extensión de aproximadamente 2700000 km² con su principal afluente el río Paraguay, involucrando zonas de aporte de Bolivia, Paraguay, Brasil y Argentina. Sintéticamente puede afirmarse que los caudales del río Paraná se originan mayormente a partir de las lluvias que se producen en las cuencas tributarias del Alto Paraná (Brasil), río Iguazú (Brasil y Argentina) y río Paraguay (Paraguay, Argentina y Bolivia). El régimen del río siempre se caracteriza por ciclos y alternancias de crecidas y bajantes (o estiajes), presentándose ambos extremos con diversos grados de severidad y extensión temporal. Respecto a la bajante extraordinaria ocurrida en el período de los años 2019 y 2022, entre las causas pueden mencionarse la variabilidad y cambio climático; las alteraciones en las condiciones de escurrimiento debido a modificaciones en los usos del suelo (deforestación, prácticas agrícolas intensivas con monocultivos, eliminación de bajos naturales, incendios, canalizaciones no planificadas y clandestinas); entre otras. Este tipo de evento extraordinario produce impactos en numerosos aspectos relacionados con el ambiente fluvial tales como alteraciones en los servicios ecosistémicos de los humedales (flora, fauna, calidad del agua, alteraciones en los suelos). También impacta en las obras de infraestructura como por ejemplo las tomas de agua para abastecimiento y en el transporte fluvial de cargas entre algunos de los efectos de dicha bajante. En este número especial de la revista se presentan y difunden algunos trabajos referidos a las causas y los impactos de la bajante extraordinaria del río Paraná del período 2019-2022 mediante el aporte de las diferentes disciplinas involucradas en esta temática. El contenido de esta sección puede resultar de interés para investigadorxs, docentes, técnicxs, estudiantes y profesionales vinculados con la temática. El consejo editorial de la Revista agradece a lxs profesionales por la contribución realizada para la difusión. A bacia do rio Paraná tem uma extensão de aproximadamente 2.700.000 km com seu principal afluente, o rio Paraguai, envolvendo áreas de contribuição da Bolívia, Paraguai, Brasil e Argentina. De forma sintetica, pode-se afirmar que os caudais do rio Paraná têm origem principalmente nas chuvas que ocorrem nas bacias tributárias do Alto Paraná (Brasil), do rio Iguaçu (Brasil e Argentina) e do rio Paraguai (Paraguai, Argentina e Bolívia). O regime do rio é sempre caracterizado por ciclos e alternâncias de cheias e vazantes (ou estiagem), estando ambos os extremos presentes com diferentes graus de severidade e extensão temporal.A respeito da vazante extraordinária ocorrida no período dos anos 2019 e 2022, entre as causas pode-se citar a variabilidade e mudança climática; as alterações nas condições de escoamento devido a mudanças no uso do solo (desmatamento, práticas agrícolas intensivas com monoculturas, eliminação de várzeas naturais, incêndios, canalizações não planejadas e clandestinas); entre outras. Este tipo de evento extraordinário produz impactos em inúmeros aspectos relacionados com o ambiente fluvial, tais como alterações nos serviços ecossistémicos das zonas húmidas (flora, fauna, qualidade da água, alterações do solo). Também tem impacto nas obras de infraestrutura como tomadas de água para abastecimento e no transporte fluvial de carga entre alguns dos efeitos da referida vazante.Este número especial da revista apresenta e divulga alguns trabalhos sobre as causas e impactos da vazante extraordinária do rio Paraná no período 2019-2022 através da contribuição das diferentes disciplinas envolvidas nesta edição.O conteúdo desta secção pode ser de interesse para pesquisadorxs, docentes, técnicxs, estudantes e profissionais ligados ao tema.O conselho editorial da Revista agradece a contribuição dos profissionais para a sua divulgação.
