“…Ecological processes of nutrient cycling and flood pulse that cause anoxia in the aquatic system, a phenomenon known as diquada or decoada, have been studied as traditional ecological knowledge (Da Silva 1984), its ecological causes and effects (Calheiros et al 2018, Andrade et al 2015. The impacts of this ecological process may have its dimensions expanded due to large nutrient intake caused by inadequate activities in the flooded areas of the Pantanal and the Paraguay River Basin as a whole (Hamilton et al 1997).…”

The aim of this work was to evaluate the gaps, trends and advances in the uses of the concepts of flood pulse and climate change through the analysis of scientometrics in Limnology in the Pantanal, between the years 1990 to 2021. The most studied ecological groups and rivers were: aquatic macrophytes and phytoplankton, and Cuiabá and Paraguai, respectively, with the highest number of article publications between 2016-2020. The temporal dynamics of social networks showed the presence of new local institutions, from other Brazilian and international states in the last 20 years. Studies on climate change are still incipient, while those related to the flood pulse are more frequent in the Pantanal. Trends and advances were found in the ecosystem approach of the flood pulse, related to the height of the water level. Few studies address the flood pulse in terms of duration and frequency. The flood pulse is shown as a consolidated concept, emerging as a highly sensitive tool in the face of short, medium and long-term environmental changes, such as climate change, making it possible to identify and deal with socio-environmental challenges and point out participatory governance mechanisms.

“…As intervenções no fluxo hídrico fragmentam habitats, alteram a biodiversidade e impedem a migração reprodutiva de peixes, além de, em alguns casos, reter água, nutrientes e sedimentos, alterando o curso natural desses elementos que são necessários para o funcionamento dinâmico de uma planície de inundação.

A elaboração do Plano de Recursos Hídricos caracteriza-se em um processo de estudo, diálogo e consenso contínuo, fornecendo um contexto da situação real dos Recursos Hídricos em diferentes realidades e cenários. Neste sentido o objetivo deste trabalho foi analisar o processo de participação social na elaboração do Plano de Recursos Hídricos da Região Hidrográfica do Alto rio Paraguai, entre os estados de MT e MS. Foram realizadas oficinas onde os participantes eram agrupados em categorias de stakeholders, para discutir os desafios e as potencialidades identificados na bacia. Os resultados demostraram que os temas mais recorrentes estavam relacionados com: saneamento básico, excesso de pequenas centrais hidrelétricas (PCH’S), uso indiscriminado de agrotóxicos, pesca predatória, queimadas, proteção dos recursos naturais, recuperação e conservação das nascentes, implementação de modelo de turismo ecológico e conservação da biodiversidade. Embora o estudo tenha identificado diferenças na representação dos grupos sociais, todos demonstraram interesse na elaboração do Plano de Recursos Hídricos da Região Hidrográfica do Alto Paraguai.

“…The advancement of unsustainable agroecosystems in the UPB’s plateau region has resulted in higher sediment and nutrients inputs to the Pantanal lowlands, and subsequently reduced the provision of ecosystem services, such as nutrient retention and recycling, water purification, and fish stocks, among others (Bergier, 2013). Additionally, the Pantanal has been becoming continuously and gradually contaminated by pollutants, such as nitrogen, phosphorus and agrochemicals, from agricultural activities (Calheiros et al., 2006). Therefore, there is an urgent need to understand the drivers of changes to nutrient cycling in the plateau region, where the VRW is located, and to adopt good practices that minimize the impacts of the land use change on ecosystem service provision.…”

The exponential growth of anthropogenic activities over the last century has altered the biogeochemical cycles on a global level (Sutton et al., 2013). The scale of these changes has increased the need to develop joint approaches that both optimize nutrient flows and produce food, fiber, and energy for the growing societal demand. This has to be done while reducing threats to social and economic well-being, such as climate change, ecosystem services and human health threats (UNEP, 2019). Nitrous oxide (N 2 O), nitrogen oxide (NO x) and ammonia (NH 3) emissions, and losses of nitrogen (N) and phosphorus (P) compounds to water systems, are some of the direct consequences of changes in the biogeochemical cycles. These emissions and other losses affect the sustainable use of natural resources, human health, resource management, livelihoods, and economies (Abrol et al., 2017; Sutton et al., 2013; van Grinsven et al., 2013). The production of enough food to meet human demand could threaten the environment and human health if nutrients are not adequately used and managed in the process. Disruptions to aquatic systems, such as eutrophication, or impact on the climate, are examples of the result of unbalanced nutrient use (Oenema et al., 2009). In contrast, when nutrients are insufficiently used in agricultural production, it can increase the risk of land-use changes from associated agricultural incursions into pristine ecosystems and depletion of nutrients and organic matter in agricultural soils, thus leading to soil degradation and increasing the risk of erosion (
