The research seeks to understand the working conditions of fishermen, the challenges posed by the precariousness of vessels and the lack of adequate regulation, and to propose measures to mitigate risks and promote safety in fishing activities. The work is divided into two main chapters. The first chapter presents a systematic literature review on maritime accidents, focusing on fishing vessels, using databases such as Google Scholar, SciELO, and Scopus. The review addresses topics such as safety culture, accident prevention, and the challenges faced by artisanal fishermen, highlighting the importance of maritime regulation and the implementation of public policies for occupational safety. Thirty articles published between 2007 and 2024 were selected, which demonstrate the need for preventive measures and training to reduce the occurrence of accidents. The second chapter focuses on the practical analysis of risks and accidents in the fishing communities around the Itaqui Port Complex. The methodology included field visits, application of questionnaires, and the use of the Design Science Research (DSR) method to identify and propose solutions to the identified problems. The main vessels used (canoes, bianas, and boats) were analyzed, along with the risks associated with each and the socioeconomic and environmental impacts of maritime accidents. The research also developed risk maps using AutoCAD software, which allowed the visualization of the main points of vulnerability in the vessels. The results indicate that bianas are the vessels with the highest incidence of accidents, followed by canoes and boats. The lack of formal safety training and inadequate maintenance of vessels were identified as critical factors that increase the vulnerability of fishermen. In addition, the research highlighted the need for public policies that promote the training of fishermen, the improvement of vessel conditions, and the implementation of accessible safety technologies. The dissertation concludes that safety in artisanal fishing is a complex challenge that requires the integration of traditional knowledge, effective regulation, and investments in infrastructure and technology. The research contributes to the understanding of the risks faced by fishing communities and provides subsidies for the development of public policies that promote the sustainability of fishing activities and environmental protection.

The study was structured based on the development of four scientific articles that addressed different dimensions of the occupation and transformation of these basins, in addition to an analysis of environmental legislation. The methodology included a literature review, analysis of current environmental and urban planning legislation, and mapping of the filled areas using geoprocessing and remote sensing techniques, allowing the identification of the spatial evolution of these interventions over time. The results showed a significant growth in filled areas, associated with the accelerated urbanization process and, in many cases, the absence of adequate planning. Direct impacts on hydrological dynamics were observed, such as reduced natural drainage capacity, intensified flooding, and degradation of aquatic ecosystems, in addition to the exacerbation of social vulnerabilities and economic impacts related to the loss of ecosystem services and increased public costs. Finally, the dissertation highlights the importance of continuous monitoring, strengthening public policies, and integrating urban planning and watershed management, in line with the Sustainable Development Goals (SDGs), aiming to promote more sustainable and resilient cities.

This study aimed to analyze the political-institutional framework of coastal zone management in the four municipalities of Ilha do Maranhão (São Luís, São José de Ribamar, Raposa, and Paço do Lumiar), proceeding with a critical evaluation of governance based on established criteria and identifying its structural limitations and socio environmental constraints. Adopting a mixed methodological approach, predominantly qualitative and descriptive-exploratory in nature, the research was structured in four interdependent chapters: Chapter I – Foundations on Coastal Zone Management and Interfaces with the Sustainable Development Goals — used a literature review (hybrid, narrative and systematic) to ground Coastal Zone Management, highlighting its interrelation with the Sustainable Development Goals (SDGs) of the 2030 Agenda (especially SDGs 6, 11, 13, 14, 15 and 17); Chapter II – Integrated Coastal Zone Management in Brazil and the Development of Management Instruments, conducted a comprehensive survey of the legal framework and discussed the principles and practices of coastal governance, highlighting the institutional challenges that hinder the effectiveness of actions; Chapter III – Analysis of the Political and Institutional Framework of the Coastal Zone of Ilha do Maranhão – used documentary analysis (Master Plans, Land Use and Occupation Laws, and budgetary instruments PPA, LDO, LOA) and secondary indicators (IBGE, SINISA) to analyze the economic, social, and environmental dimensions of the four municipalities studied; and Chapter IV – Application of Barragán's Decalogue (2004) as an Instrument for Evaluating the Coastal Management Structure of the Municipalities of Ilha do Maranhão – applied the methodology of Barragán's Decalogue (2004) through semi-structured interviews with public environmental managers (municipal and state). The research revealed institutional fragility, federative asymmetry, and disarticulation between public entities, in addition to the absence of Municipal Coastal Management Plans (PMGC) and Integrated Coastal Management Plans (PGI). The critical interview with Professor Barragán (2025) validated the diagnosis and guided the propositional phase, indicating that overcoming fragmented management requires the construction of cooperative and integrated governance, supported by the articulation of three strategic axes: alliances, instruments, and resources. It is concluded that the effectiveness of coastal management on Maranhão Island is incipient and is conditioned by institutional strengthening, inter-federative integration with social participation, and budgetary and financial guarantees for coastal management. The research reaffirms the need to fully incorporate the coastal and marine dimensions into municipal planning instruments to consolidate management aligned with the principles of sustainability and the SDGs.

It is a complex environment with irregular geometry and morphology, low river flow and a large tidal range (3.75 m). The aim of this study was to classify and characterize marine sediments (granulometry and morphoscopy) and sediment transport trends using the Multi Sediment Trend Analysis (MSTA) model. The surface sedimentary cover of this platform consists mainly of quartz sands. Based on carbonate concentrations, two sedimentary facies were recognized, one terrigenous and one biogenic, the former predominating on the inner continental shelf and the latter on the outer shelf. Muddy sediments from before the Last Postglacial Marine Transgression could be recognized, and are currently undergoing a rapid erosion process. Bathymetry within the sampling grid shows sandy banks at shallow depths and evidence of submarine canyons on the outer shelf in connection with the paltaform break. The MSTA model indicated a trend of transport from both the inner and outer shelf converging on the middle shelf, as a result of an improvement in particle size selection.
