The research hypothesis assumes that the beach morphology and sedimem budget of these areas are influenced by rigid artificial structures built along the shoreline. Thus, the aim of this stady was to analyze the influences of rigid trtificial structures on the local hydrodynamic and morphosedimentary processes of Seixas and Cabo Branco beaches in João Pesson-PB. To achieve these goals, the following methodological procedures were adopted: (1) monitoring four transversal topographic profiles (P1 to P4) along the shadied beaches over a 13-month period to observe beach morphology dynamics; (2) quantifying sediment balance during the study period across the four transversal profiles, (3) estimating shoreline changes through a multitemporal analysis (2016-2024) using the CASSIE platform, and (4) Atalyzing marine hydrodynamics using the SMC-Brasil model for the period from 1948 to 2008. The results showed that profile P1 (near Cabo Branco viewpoint) presented slight accretion (3.38 m³/m), probably due to wave reflection generated by the nearby structure: profile P2 (near the Cabo Beatco cliff), a sector with riprap, also showed mild accretion (2.06 m³/m), profile P3 (located on the sandy point of Seixas bench) recorded higher accretion (8.60 m²/m), whereas profile P4 (the southernmost profile) exhibited accelerated erosion (-9.04 m/m). Regarding shoreline changes, the northern portion of Cabo Branco beach (transects 9 to 50) was characterized by stability or accretion, while transects 51 to 105 (southern portion) showed a predominant erosive trend. Transects 115 to 117 (the sandy point at the northern part of Seixas bench) displayed a tendency toward accretion. In contrast, iransects 106 to 114 and 118 to 147 (central and southem portions of Seixas beach) were predominantly stable to accretion. As for marine hydrodynamics, the results indicate that during periods of higher meteorological energy, such as winter and spring, currems, winds, and waves become more effective, producing higher sediment transport rates. However, the mean transport/flow outputs geherited by the SMC model revealed predominantly negative sediment transport values across four of the five transversal profiles, except for profile 4, which remained positive throughout all analyzed periods. In summary, the findings highlight the complexity of this coastal environment, which is constantly changing depending on natural energy variations, as well as athropogenic interferences that restrict natural sediment mobility, thereby generating or intensifying several envirımmental problems in the area.

However, areas that have a semi-arid climate and are susceptible to a high succession of dry years, which favors a greater occurrence in the outbreak of climatic disasters, also present vulnerabilities in this scenario. In view of this, the present research aims to analyze the different degrees of socio-environmental vulnerability in the face of the risks of climatic disasters in the rainfall region of Cariri/Curimataú in Paraíba. Regarding the methodological procedures, the research is in line with the proposal defined by Cunico et al. (2021) and, through this, it was possible to identify syntheses that reflect the condition of infrastructure, income and social situation, which superimposed, resulted in social vulnerability by census sector; susceptibility to drought/drought and socio-environmental vulnerability, the latter resulting from the overlapping of social vulnerability and susceptibility to drought/drought. For each synthesis, as well as for social vulnerability, susceptibility to drought/drought and socio- environmental vulnerability, five classes were established, ranging from very low to very high vulnerability conditions. In addition, a survey was carried out of the ordinances for recognizing climate disasters and the disaster information forms, which provide data about the damages and losses caused by them for the period from 2003 to 2016, whose supply is made available. through the website of the Integrated Disaster Information System – S2ID, maintained by the Ministry of Regional Development. Regarding the results, the 35 municipalities analyzed account for 431 census sectors, thus, it was found that in the infrastructure synthesis, the municipalities present a good condition, that is, they are inserted in the very low and low classes; the income synthesis showed a variation between very low and high classes; in the synthesis of the social situation, the sectors are inserted in the very low to middle classes. As for social vulnerability, there is a greater concentration of sectors in the middle class, however, in the very upper class, of the 431 sectors accounted for in the study area, 21 sectors are included in it. With regard to susceptibility to drought/drought, the lower class has the largest number of sectors, totaling 176. With regard to socio-environmental vulnerability, the classes that indicate a high degree of vulnerability, established by the upper and very high classes, add up to 52 census sectors, being 39 rural sectors. Regarding climate disasters, it was found that during the 14 years of analysis, 642 occurrences were recorded, with the highest number of affected (205,630 and 253,031 respectively) in the years 2003 and 2016. An economic loss of around R$ 362,317,767.50 was recorded for the study area, encompassing the agriculture, livestock and services sectors and, in relation to social losses, there are records of damages to the water supply, education and in health. That said, the research becomes important for the possibility of subsidizing studies on the subject in semi-arid areas, as well as for managers, aiming to mitigate the damage to which the resident population is exposed, due to climatic disasters.

The research adopts a critical and Afrocentric perspective, deeply informed by the author’s personal experiences as a Black woman, teacher, capoeirista, and activist. The study is situated within the debates on the implementation of Law 10.639/2003 and the struggles surrounding the curriculum as a tool for resistance, memory, and social justice. Teacher education, in this context, is understood as a field where scientific knowledge, territorial experiences, and collective memories intersect, demanding an approach that transcends technical and neutral boundaries. For this purpose, the study pursues three specific objectives: to understand the significance of Law 10.639/2003 for geography teacher education; to identify the presence of ethnic-racial relations content in the syllabi of the mandatory curricular components; and to analyze the experiences of instructors who have taught the subject alongside students’ impressions of the component. The methodology includes bibliographic research, document analysis, and focus groups with faculty members, current and former students, and members of NEABI (Núcleo de Estudos Afro-Brasileiros e Indígenas). Data were analyzed using Bardin (2011) content analysis technique, allowing for the construction of categories that highlight ERER institutional trajectory, its formative impacts, and pedagogical meanings. Key theoretical references include Freire (1992, 1996), Evaristo (2020), Anjos (2011, 2014), Miranda (2020), Gomes (2011), Munanga (2005, 2015), Arroyo (2017), Zeichnner (2008), Santos (2010), Ratts (2010), among others. One of the study’s innovations is the incorporation of authorial cartographies, created based on the author's life itineraries. These maps, inspired by Anjos (2011) Black cartographies, break from the Euclidean and technical tradition of academic cartography, especially using colors and shapes, while still maintaining features essential for spatial orientation. They represent personal and collective trajectories — from childhood in Jaboatão dos Guararapes/PE to academic activity in João Pessoa/PB — and symbolize the body as a territory of knowledge, resistance, and transformation that underpinned the construction of this dissertation. The findings indicate that the ERER component is recognized as a powerful tool for training teachers committed to antiracist pedagogical practices. However, its implementation still faces structural limitations, such as thematic isolation and lack of integration with other curricular components. The research demonstrates that while the inclusion of ERER in the curriculum is a significant advance, it is not sufficient: the transversal integration of ethnic-racial relations in geography education still needs to be consolidated. It concludes that the effective implementation of Law 10,639/2003 in teacher education requires a political commitment from educational institutions to Black, Indigenous, and peripheral epistemologies. The study affirms that the curriculum is not neutral and that the inclusion of ERER should be understood as historical reparation, a strategy to combat racism, and a means to build a more critical, plural, and engaged geography.

This study aimed to characterize the vulnerability to coastal erosion in the beaches of Lucena (PB), Brazil, using geotechnologies and geoindicators. To achieve this, methodologies for analyzing shoreline variation were applied through the CASSIE (Coastal Analysis System via Satellite Imagery Engine) tool, combined with the identification of specific geoindicators such as beach morphology, dune presence, wave exposure, coastal vegetation, and soil impermeability. Field data were collected and integrated with remote sensing images to obtain a coastal vulnerability index. The results indicate significant shoreline variations over the past decades, highlighting sectors with trends toward intense erosion and areas with relative sedimentary stability. The integration of geotechnologies with geoindicators enabled the identification of spatial patterns of vulnerability, providing support for coastal planning and environmental management in the municipality. It is concluded that the adopted methodology proved to be efficient in assessing coastal vulnerability, serving as an essential tool for decision-making in public policies aimed at mitigating the impacts of erosion and preserving coastal ecosystems.
