Title: Gestão hídrica e desenvolvimento rural sustentável: desenvolvimento de um sistema utilizando georreferenciamento e inteligência artificial para prevenção de erosão em mananciais de abastecimento público Autor: Ribeiro, Alison Antony Primeiro orientador: Corrêia, Arlindo Fabrício Abstract: The intensification of agricultural land use in rural watersheds has increased erosion processes and compromised the quality and availability of water resources, especially in areas dominated by family farming. The aim of this thesis is to develop and validate an integrated methodology based on aerial photogrammetry using Remotely Piloted Aircraft Systems (RPAS), geoprocessing, derived attributes calculated from RGB orthomosaics, artificial intelligence, and independent validation using the Revised Universal Soil Loss Equation (RUSLE), with the goal of identifying areas susceptible to erosion, simulating environmental restoration scenarios, and informing strategies for water management and sustainable rural development. The study was conducted in a 59.24-hectare area located in one of the headwaters of Arroio Fundo, a public water source for the municipality of Marechal Cândido Rondon (PR), situated on the border with the municipality of Quatro Pontes, in western Paraná. The methodology involved the acquisition of multitemporal aerial images via UAV with a spatial resolution of 3.7 cm/pixel, the development of an automated computational pipeline for photogrammetric processing, the generation of derived attributes, the preparation of data for training the neural network, and the semantic classification of land use and land cover. For land use and land cover classification, a U-Net-type convolutional neural network was used, optimized through data augmentation and class weighting strategies, and subsequently integrated with topographic variables to model erosion risk using map algebra. The consistency of the results was verified using the RUSLE. The results of the current scenario assessment (2025) showed that 60.31% of the study area is at high risk of erosion, with 1.61 hectares of active erosion processes identified, for which the average soil loss estimated by RUSLE reached 114.52 t ha⁻¹ year⁻¹. The simulation of the prospective scenario (2035) indicated that the full restoration of Permanent Preservation Areas could completely eliminate areas at critical risk and reduce high-risk areas by 72.8%, with a 319.9% increase in low-risk areas. The proposed integrated methodology is a technical tool with low operational costs, based primarily on free and open-source software, with the potential to be replicated by municipal technical teams and research institutions in similar rural contexts, contributing to territorial planning geared toward sustainable rural development.

Title: Políticas ambientais, hídricas e sustentabilidade na tríplice fronteira do Alto Rio Solimões Autor: Silva, Edson Luis de Carvalho Primeiro orientador: Roesler, Marli Renate von Borstel Abstract: Water management in the tri-border region of Brazil, Colombia, and Peru presents a significant challenge, particularly given the abundant water resources of the Amazon Basin and the social, environmental, and institutional complexities involved. Despite the abundance of water resources, the region suffers from structural problems such as a lack of basic sanitation, unplanned urban expansion, pollution of water bodies, and vulnerability to extreme weather events. The relevance of the topic is grounded in its direct contribution to the Sustainable Development Goals (SDGs), particularly SDG 6 (Clean Water and Sanitation), which addresses access to clean and safe water; SDG 3 (Good Health and Wellbeing), by highlighting health risks; SDG 13 (Climate Action), given the vulnerability of communities to extreme events; and SDG 17 (Partnerships for the Goals), by reinforcing the importance of international and inter-institutional cooperation in the shared management of water resources. This study aimed to understand the multiple uses of water and its management in the Upper Solimões River region, taking into account the specific characteristics of the three countries involved. The institutional and legal frameworks were analyzed, identifying the actors and social relations that make up the water management network, and the nature of shared uses was evaluated. The research was conducted using a qualitative approach, with an exploratory and descriptive nature. A case study was adopted as the technical procedure, focusing on the municipalities of Tabatinga, Benjamin Constant, and Atalaia do Norte (Brazil), Leticia (Colombia), and Islândia/Santa Rosa Island (Peru). Data collection was carried out in three stages: a review of literature and documents; the identification of local actors and institutions; and in-depth interviews with water management stakeholders. The results demonstrate that, although the Alto Solimões region possesses abundant water resources, it faces serious challenges regarding integrated resource management. An absence of effective governance mechanisms and a deficiency in institutional coordination among the three countries were observed. Environmental management is fragmented, with limited civil society participation and strong pressure on natural resources from private sectors such as fishing. It was found that riverine communities depend directly on water bodies for consumption, hygiene, production, and transport, yet they contend with pollution and waterborne diseases. The thesis concludes that water resource management in the tri-border area requires a cooperative, transboundary approach, involving institutional strengthening, integration among stakeholders, and investment in infrastructure and environmental education. Social participation and the recognition of local knowledge are key elements for the region's water sustainability. Publisher: Universidade Estadual do Oeste do Paraná Tipo do documento: Tese

Title: Stakeholder engagement: dinâmica relacional para conservação de solos e recuperação de matas ciliares em sustentabilidade rural Autor: Diniz, Antônio Marcos Primeiro orientador: Walter, Silvana Anita Abstract: This thesis analyzes soil conservation and riparian forest restoration in Nova Santa Rosa (PR), Brazil, through the theoretical lens of stakeholder engagement, focusing on relational dynamics among territorial actors in rural contexts characterized by normative instability. The study addresses a gap in literature: although significant advances have described institutional instruments of environmental governance, limited attention has been given to the relational and institutional mechanisms through which conservation practices are sustained over long term. Methodologically, the research combines an international qualitative meta-synthesis of case studies (n = 7) with a longitudinal empirical analysis, which is based on the Gioia method and supported by in-depth interviews and historical documents. The integration of the metasynthesis and empirical findings allows relational engagement to be interpreted as the central explanatory axis, mediated by mechanisms associated with crisis perception, social legitimation, economic viability, intergenerational learning, productive consolidation of conservation practices, formal regulatory enforcement, and local autonomy. Together, these mechanisms explain the long-term stability of conservation practices. As an analytical synthesis, the thesis proposes the Systemic Collaborative Engagement Framework (FECS), within the relational dynamics of stakeholder engagement, offering an interpretation of how local collaborative structures maintain continuity amid regulatory fluctuations. By shifting the explanatory focus from policy instruments to relational mechanisms, the thesis contributes to the debate on stakeholder engagement in rural sustainability, elucidating how values, processes of social legitimation, and territorial arrangements interact to sustain conservation practices over time.

Title: Educação Ambiental na Educação Fundamental com vista ao Desenvolvimento Rural Sustentável Autor: Ferreira, Magda Gonçalves Primeiro orientador: Oliveira, Irene Carniatto de Abstract: The global environmental crisis is one of the greatest challenges of the twenty-first century, rendering environmental education (EE) an urgent political and formative instrument, particularly in elementary education, with the aim of shaping critical individuals committed to sustainability. In rural contexts, such as Marechal Cândido Rondon, EE becomes even more strategic, as it engages directly with sustainable rural development and therefore requires an analysis of curricula and methodologies. Historically, EE consolidated after milestones such as the Clean Air Act in England and the work Silent Spring (1962), driven by the intensification of the environmental crisis. The general objective of this research is to investigate the importance of EE in elementary education for the promotion of sustainable rural development. Its specific objectives are to evaluate EE practices within the school environment, identify the challenges faced by rural educators, and assess the impact on children’s environmental awareness. The methodology adopted is mixed (documentary and fieldbased), combining document analysis with questionnaires, semi-structured interviews, and participant observation in rural schools, thus assuming a descriptive and exploratory character. The study is organized into three chapters. Chapter 1, “Legal Foundations and Humanized Practices,” examines the Brazilian legal framework (Law No. 9,795/1999), which establishes EE as an essential, permanent, and crosscurricular component, emphasizing the central role of the teacher as mediator, model, and agent of transformation, as well as the importance of affectivity and direct contact with nature. Chapter 2 evaluates how the intensification of climate change requires the integration of science education in the early years of elementary schooling in order to promote critical thinking and children’s protagonism, treating climate education as a structuring theme. Chapter 3, “Assessment of Practices,” seeks to evaluate, through questionnaires administered to students, parents, and teachers in the rural area of Marechal Cândido Rondon, the recognition of the relevance of the theme and children’s understanding of concrete environmental problems, although without the incorporation of personal actions. For teachers, the pedagogical difficulties encountered—whether related to materials or to long-term projects—constitute limits that are difficult to overcome. Given the community’s strong connection to agricultural activity, the full implementation of EE in the school is essential.
