Hydrometeorological monitoring using wireless sensor networks
Urban floods are among the most frequent types of disasters on the planet. They are often pre-existing occurrences due to the region's physiographic characteristics, but they are exacerbated by the effects of urbanization, including waterproofing and modification of the hydrological cycle due to human activities. Approaches to addressing these events range from structural solutions, involving macro-drainage projects, to non-structural solutions, including land use regulations. In the context of Smart Cities, mitigation actions include the use of technologies such as the Internet of Things (IoT) and computerized urban security management to improve the response to extreme hydrometeorological events. From this perspective, this work aims to propose sensor nodes and gateways for the creation of Wireless Sensor Networks (WSNs) for hydrometeorological monitoring and flood forecasting. The work was based on a scientific review of the literature and technical manuals, including the selection of development boards, communication module, sensor modules, coding, and testing. The tests demonstrated that microcontroller systems can comprise a WSN, processing data collections every few seconds at low cost and with low power consumption. Furthermore, sensor nodes are scalable and versatile, incorporating a variety of sensors and communication protocols.
Treatment of industrial effluent by bench-scale microfiltration aiming at water reuse
Objective – To evaluate the bench-scale microfiltration process for the treatment of industrial effluent generated from the CIP (Clean in Place) system of a brewery, analyzing color, turbidity, and pH as quality parameters, and verifying the effect of centrifugation as a pretreatment step aiming at non-potable water reuse. Methodology – The study was carried out at a bench scale, employing centrifugation as a preliminary stage and microfiltration using glass fiber membranes with pore size < 1.0 µm. Color (Pt-Co), turbidity (NTU), and pH analyses were performed in triplicate, following AWWA (2012) standards. Five tests were conducted: three with raw effluent (50, 100, and 150 mL) and two with centrifuged effluent (50 mL with a new membrane and 50 mL with a reused membrane). Originality/Relevance – The study explores the combination of centrifugation and microfiltration for treating CIP effluent, a scarcely investigated approach in brewery wastewater management. It provides a low-cost and practical alternative for industrial water reuse, aligned with the Sustainable Development Goals. Results – Centrifugation promoted approximately 82% color and 95% turbidity removal, proving to be an effective pretreatment. Microfiltration applied directly to raw effluent showed early membrane fouling and removals below 30%. Conversely, microfiltration of the centrifuged effluent reduced color to 128 ± 2.5 Pt-Co and turbidity to 112 ± 2.0 NTU, achieving removals above 85%. Membrane reuse showed decreased color removal efficiency due to fouling accumulation. Theoretical/Methodological Contributions – This study enhances the understanding of membrane fouling during the treatment of alkaline effluents and provides a reproducible experimental model for comparative future studies. Social and Environmental Contributions – The research reinforces the feasibility of water reuse in non-potable brewery processes, contributing to water resource conservation and the reduction of industrial effluent discharge.
Objective: The present study aimed to discuss the relevance of critical Environmental Education (EE) in addressing urban solid waste management issues, highlighting the limitations of reductionist and pragmatic approaches that still prevail in educational practices. Methodology: The work was developed within the scope of the extension project “Environmental Education as an Educational Process for Urban Solid Waste Management”, linked to the Federal University of Technology – Paraná (UTFPR), Dois Vizinhos Campus. The activity was carried out during the 2025 Environment Week in Francisco Beltrão (PR), through the event “What’s in the container?”, which consisted of the public opening of an organic waste container. The proposal aimed to reveal the local reality of waste collection, promote dialogue among different social actors, and raise community awareness about the consequences of improper waste disposal. Originality/Relevance: The study proposes a critical and participatory approach to EE, going beyond the merely instrumental nature of actions focused on recycling and waste collection. Based on authors such as Layrargues (2002) and Gonzaga (2016), the work highlights the need for Environmental Education that addresses political, social, and cultural dimensions, as guided by the National Environmental Education Policy (Law No. 9.795/99), the 1988 Federal Constitution, and the National Common Curricular Base (BNCC, 2017). Results: The waste analysis revealed that approximately half of the container’s contents consisted of recyclable materials mixed with organic waste, which made their reuse and/or recycling unfeasible. This result demonstrated deficiencies in the segregation process, a lack of public awareness, and non-compliance with the National Solid Waste Policy (PNRS) goals. The action, therefore, highlighted the gap between environmental legislation and the daily practice of waste management. Theoretical/Methodological Contributions: The project reaffirms the importance of continuous teacher education, as pointed out by Valentin (2014), and demonstrates the potential of university extension in linking teaching, research, and social practice, as defended by Sousa et al. (2017). Methodologically, the activity exemplifies using critical EE as an investigative and dialogical tool, integrating academic and popular knowledge and fostering collective reflection on sustainability and socio-environmental responsibility. Social and Environmental Contributions: The action generated social impact by involving students, teachers, waste collection workers, and public authorities in a space for dialogue and reflection on waste management. From an environmental perspective, it raised community awareness about the importance of proper material separation and reduced impacts such as soil and water contamination. Thus, it reinforces the relevance of non-formal Environmental Education and university extension as instruments of social transformation and promoters of sustainable practices aligned with the Sustainable Development Goals (SDGs), especially SDG 4 (Quality Education), SDG 11 (Sustainable Cities and Communities), SDG 12 (Responsible Consumption and Production), and SDG 13 (Climate Action).

Green infrastructure as a Nature-based Solution for mitigating impacts on urban drainage in São Paulo
The disorganized growth of the city of São Paulo, with the occupation of floodplains, the canalization of rivers and streams and waterproofing, has caused several problems in the city, including floods and recurrent flooding during heavy rainfall events. As a way of solving the problem, the public authorities have come up with rainwater detention reservoirs, known as 'piscinões', which reduce the volume of water in the drainage network, but dispose of the rainwater and with it all the pollution that reaches it. Based on an exploratory literature review, this article sought to map the main studies carried out on green infrastructure as a nature-based solution for urban drainage in São Paulo and, with this, to verify its applicability in the search for solutions to adapt the city. The studies showed good results in the implementation of green infrastructure for urban drainage, but some of them found errors in design or execution. In addition, even though the government indicated in the revision of the Master Plan that the drainage system should prioritize nature-based solutions, the solution adopted for the city's flooding problems is the installation of “piscinões”.

This study investigates the effectiveness of educational games in the learning process of elementary school students, focusing on raising awareness about water conservation. The "Water-Path Game" was applied to 40 public school students aged 9 to 10 from Penedo-AL, aiming to make learning more engaging and interactive. In addition to promoting conscious water use, the game was designed with inclusive mechanics, using symbols and illustrations to help children in the process of literacy or with cognitive difficulties. The research also involved 10 teachers with experience ranging from 5 to 12 years, who evaluated the game's impact compared to traditional teaching methods. Using a scale from 1 to 5, both teachers and students expressed a high level of satisfaction and recognized gamification as an effective tool for developing cognitive skills such as critical thinking and problem-solving. The activities were highly approved by students and teachers, highlighting the potential of innovative pedagogical practices in the school environment.
Study for the Adaptation of a Rapid Assessment Protocol for Lentic Environments in Presidente Prudente (São Paulo/Brazil)
Amid the context of urban transformation that extends from the earliest settlements along the banks of rivers and streams to the present day, it is evident that in the process of urban planning and occupation, these water bodies were often perceived as barriers that limited and shaped the urban layout. The objective of this study was to develop a study for the adaptation of a rapid assessment protocol focused on lentic environments in Presidente Prudente, São Paulo. This study fills a theoretical gap by addressing the lack of specific adaptations for lentic environment assessment protocols. The research was conducted through literature reviews comparing the characteristics of lentic and lotic environments, and the results revealed that lentic environments exhibit several characteristics that differentiate them from lotic environments, highlighting the need for continuous adaptations in the assessment protocol. This analysis not only contributes to academic knowledge but also points to the need for more effective and sustainable management practices concerning these ecosystems.
The present study deals with the memories of the construction of the Banguê Dam as a determinant in the civilizing production of the history of Assaré, linked to the protagonism of the black population of the place. The research aims to study the use of African-based techniques and technologies in the formation of cities belonging to Cariri Ceará. The Banguê Dam, an artificial water reservoir built in the mid-19th century, using the work of enslaved labor, but which was recognized in the history of the place as being created by the colonizer. To carry out the research, the methodology of Afro-descendants was used, associated with oral history with the use of narrative interviews with residents who had knowledge about the formation of the Alto de Banguê neighborhood. Given the ideologies imposed by Eurocentrism in the framework of the origin of cities in the interior of Ceará, there is a lack of knowledge in identifying Afro-descendant belonging in the production of cities. In this way, our interest in presenting possibilities for developing geography teaching, using the spatialities of the place in the production of the territory linked to the local slave past, positive the belonging of the black population at the origin of the municipality.

This project aims to investigate the pollution of the Beberibe River, analyzing its causes, impacts and possible solutions to mitigate environmental degradation. The methodology adopted involves a theoretical approach with a literature review on water pollution and its consequences. The study contributes to the advancement of knowledge in the area of ​​water resources management, offering a detailed analysis of the contaminants found, such as heavy metals and cyanotoxins, which compromise the health of aquatic ecosystems and the population that depends on the river. Among the results, the proposal to implement the Ecobarreira stands out, which aims to contain floating waste dumped in the river. Theoretical contributions expand the discussion on water pollution in urban contexts, highlighting the need for more effective public policies. The social implications include raising public awareness about the risks of pollution and promoting sustainable practices, while environmental contributions include the recovery of the river and the preservation of water resources, aiming to improve the community's quality of life.
