The article addresses the challenges faced by regions under water stress, such as conflicts over water use, environmental degradation, and water resource scarcity, intensified by climate change. In areas dependent on hydropower generation, these problems are exacerbated, highlighting the need to transition to more sustainable and resilient energy sources. The study emphasizes the importance of multifaceted criteria for an effective transition of the electricity matrix in semi-arid regions, taking into account economic, technical, environmental, and social aspects. Focusing on the São Francisco River basin in Northeastern Brazil, where the energy matrix is predominantly hydroelectric, the study uses the Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS) to evaluate alternative scenarios, analyzing options for wind, solar, and thermoelectric energy. The methodology adopted included the close collaboration of experts in defining and weighting essential criteria, covering economic, technical, environmental, and social aspects. The results show that, within the same group, options that involve greater reductions in hydroelectric generation are more advantageous. Analyzing the ranking among all alternatives, the group that includes higher expansion of wind energy presents the most viable options, followed by the reference strategy (based on average annual generation) and the group with greater expansion of solar capacity. Increasing the share of gas-fired thermoelectric power is considered a less favorable solution according to the criteria used in the model.

The expansion of urbanization has led to significant adverse environmental effects, including the disposal of domestic sewage without treatment in water bodies. This impact contributes to the deterioration of water quality and poses serious risks to human health and the environment. In this context, effective and sustainable methods to mitigate the impacts should be explored, such as the use of plants capable of removing or degrading contaminants from water. The present study aimed to assess the phytoremediation potential of two free-floating aquatic macrophytes (Eichhornia crassipes and Pistia stratiotes) systems for enhancing the water quality collected from two polluted urban streams. The trials were performed in 25-L experimental units for seven days under ambient conditions. The water quality variables after the exposure period were compared to those at the beginning of the experiment to assess the potential improvements due to the presence of macrophytes. The systems with E. crassipes exhibited good performance in water samples from both streams, with reductions reaching 29.2% in dissolved solids, 36.8% in electrical conductivity, 44% in biochemical oxygen demand, 57% in nitrogen, and 45% in phosphorus. The systems with P. stratiotes also exhibited satisfactory outcomes, including 90 and 76.2% reductions in phosphorus levels of Santa Rita Stream and Galinha Stream, respectively, and 54% turbidity, and 38% biochemical oxygen demand in both streams. These findings highlight the potential of the two plant species for phytoremediation of polluted waters, considering their performance on short-term exposure. Therefore, this approach consists of a sustainable alternative by utilizing natural elements for environmental restoration, and the outcomes can contribute to future applications of phytoremediation techniques in developing countries.

Potential of two floating aquatic macrophytes in improving water quality: A case study in two tropical streams

两种浮水水生植物改善水质潜力：两热带溪流案例研究

Do crescimento urbanístico resultam diversas alterações relacionadas, principalmente, com aspectos demográficos, sociais, econômicos e ambientais, decorrendo em uma nova conotação no uso e ocupação do solo. Esse novo cenário impacta o balanço energético local, gerando, como é conhecida, uma “ilha de calor urbana”. Esta pesquisa objetiva investigar a ocorrência de ilhas de calor urbana na cidade do Recife, capital de Pernambuco, Brasil, a partir do processamento de parâmetros biofísicos, da classificação do uso e ocupação do solo e da temperatura da superfície. As imagens orbitais da região de estudo foram obtidas e processadas utilizando-se a plataforma de processamento em nuvem Google Earth Engine, para o período de 2013 a 2021. Os resultados evidenciaram a ocorrência de um aumento das áreas com maior densidade urbana e uma redução das áreas com vegetação. Constatou-se que nas regiões com maior densidade urbana, a temperatura de superfície observada foi até 5,20°C mais elevada do que na área com vegetação.

Atrazine is a pesticide commonly used in agriculture and is recognized as a potent endocrine disruptor. Due to its high recalcitrance, its residues have been found in drinking water sources throughout Brazil and the world. Therefore, this study aimed to evaluate the influence of the C/N ratio on the potential of the fungus Penicillium chrysogenum NRRL 807 to degrade atrazine from contaminated waters in submerged fermentation. Moreover, the free and immobilized forms of the fungus were compared. The fungus grown in suspended culture (free form) was able to degrade 40.08±5.71% of the atrazine present in the medium after 5 days, while the immobilized form (biofilm) degraded 48.31±1.53% in the same incubation time. Notably, atrazine was used as a carbon source, and degradation was led by the enzyme complex of the cytochrome P450. The amount of exogenous nitrogen was determined to interfere with the biodegradation efficiency, diverting the metabolism to the path of spore germination when nitrogen was present in high concentrations. Based on these results, P. chrysogenum both in its free form and when immobilized in biofilms can be used as bioremediation technologies for treating water contaminated by atrazine.

The world faces challenges with regard to water resources, including pollution and governance related to access and use. In this perspective, the study of socio-ecological resilience contributes to minimizing the problems inherent to water resources, as it offers an adaptive, participatory, and innovative approach. The aim of this article was to analyze current topics related to socio-ecological resilience in water resources (SERWR) in order to better understand the approaches used, investigate the potentialities of the topic, and identify the challenges of SERWR evaluation methods. The study is a systematic review of literature carried out by means of searches in the databases ScienceDirect and Scopus, comprising research between the years 2010 and 2022. The 30 scientific papers analyzed were classified into four topics and the results were divided into quantitative and qualitative analyses. The quantitative outcomes describe bibliometric computer analysis, and the qualitative outcomes show that involving the community and managers (stakeholders) is crucial for improving the capacity of the SERWR. Most studies reveal the multiplicity of methods and method combinations used in SERWR evaluation. Future research should focus on the creation of a comprehensive evaluation methodology capable of assessing SERWR in degradation and vulnerability scenarios, as well as preventing subsequent damage.

The aim of the article was to investigate whether the Brazilian State Water Resources Councils, including the Federal District, ensure civil society participation through access to information, parity, and decision-making procedures. In this context, verification criteria were selected, with maximum score of 1 point assigned based on their suitability for the Councils, which were classified in terms of participation adequacy. The states that were deemed suitable, in descending order, were: Paraíba (1st position), Mato Grosso do Sul, Minas Gerais, and São Paulo (2nd position), Amazonas, Pará, Paraná, Rio de Janeiro, Rio Grande do Sul, Rondônia, and Santa Catarina (3rd position), Bahia, Ceará, Federal District, Espírito Santo, and Mato Grosso (4th position), Rio Grande do Norte and Tocantins (5th position), and Alagoas (6th position). The states deemed unsuitable were: Acre and Pernambuco (7th position), Piauí and Roraima (8th position), Goiás and Sergipe (9th position), and Amapá and Maranhão (10th position). As for the criteria, the ones that scored the highest were: the presence of the website and Internal Regulations of the Councils, decision-making by the Council in plenary sessions, the presence of Meeting Minutes on the website, identification of the Technical Chambers of the Councils on these channels, adherence to the regular meeting schedule, identification of the members who make up the Councils, and parity among the three sectors that constitute them. It was concluded that the State Water Resources Councils need to ensure equal participation for civil society members in their discussions and deliberations as well as provide public access to the information generated.
