Item Cidade e formação cidadã no ensino de Geografia: desafios curriculares para o Estado do Mato Grosso(Universidade Federal de Goiás, 2025-04-29) Silva, Valdiney Vieira da; Souza, Vanilton Camilo de; Souza, Vanilton Camilo De; Cavalcanti, Lana De Souza; Bueno, Miriam Aparecida; Deon, Alana Rigo; Santos, Robson Alves dosIn geographical education, curricular issues are influenced by global and national dynamics, although they take on specific forms in the local context. In this context, the following research question arises: to what extent do official curricular policies interact with academic scholarship to promote citizenship education through the teaching of Geography? To address this question, this research sought to understand how the themes of teaching the city and citizenship formation are addressed in the curricular documents (namely the BNCC, DRC-MT, and Sistema Maxi de Ensino handouts) of Geography for Elementary Education (Final Years) in the state of Mato Grosso (MT). Furthermore, how academic production on teaching Geography, which addresses the themes of teaching the city and citizenship formation, relates to the basic education curriculum (Final Years) at MT. The methodological approach was based on qualitative research – bibliographic and documentary research – using Ball's Policy Cycle (1992) and Bardin's Content Analysis (2009). The results demonstrated that the theoretical and conceptual bases underpinning discussions on teaching about the city, citizenship, and curriculum, although influential in academic literature, have difficulties transposing into curricular documents. Furthermore, the analysis of academic production confirmed the importance of teaching about the city for citizenship formation and the challenges regarding the need for a critical and contextualized approach to urban space. The BNCC presents a structure that theoretically recognizes the importance of teaching about the city for citizenship formation, partially aligning itself with the propositions of academic research on the role of Geography in citizenship formation. However, its approach proved to be more prescriptive than reflective, distancing itself from academic propositions that defend a critical perspective on the teaching of Geography, highlighting the tensions between the declared intentions and the effective practices of curricular policies. In turn, the DRC-MT presents an attempt at regional contextualization that dialogues with the propositions of academic research on considering local specificities in teaching Geography. However, the literal reproduction of many BNCC guidelines compromises this intention, confirming academic research studies on the recontextualization of curricular policies. The limited autonomy in local curriculum construction contrasts with academic propositions about the importance of curriculum contextualization. The Sistema Maxi handouts present the most significant distance from academic propositions. Its standardized and decontextualized approach directly contradicts academic propositions about the city as a space for living and social construction. The teaching material prioritizes quantitative and visible aspects of the city, neglecting fundamental issues such as inequality and spatial segregation, elements considered crucial for understanding urban space. The results and discussions presented in this work challenge some academic research premises, especially concerning curricular policies' capacity to promote effective changes in pedagogical practices. While some theorists argue for the transformative potential of curriculum, this research indicates that implementing curriculum policies can paradoxically reinforce traditional and decontextualized practices, mainly when mediated by standardized teaching materials. However, the questions raised in this study do not end here. At the same time, they serve more than to present definitive answers; they invite the academic and school community to keep the debate on the role of teaching geography in citizenship formation alive.Item Os mapas e os livros didáticos de geografia: aproximações entre a cartografia Escolar e a linguística(Universidade Federal de Goiás, 2024-11-18) Mota, Hugo Gabriel da Silva; Bueno, Miriam Aparecida; http://lattes.cnpq.br/9765282563578698; Bueno, Miriam Aparecida; Richter, Denis; Moraes, Loçandra Borges de; Vallerius, Daniel Mallmann; Silva, Leosmar Aparecido DaWhat is understood by cartographic language in studies related to School Cartography? This is a key question in this PhD work. However, going through its answer is a complex task and requires a dialogue with the trajectory of School Cartography as a field of knowledge, as well as it was necessary to revisit the official curriculum documents and also dialogue with other fields of knowledge. That is the challenge we have set ourselves. To continue on this path, we initially carried out a movement of "looking back" by revisiting the work of great researchers of School Cartography, who over five decades discussed themes related to School Cartography in different contexts and objectives, but who were able to identify weaknesses, resistances and also courageous in proposing solutions to overcome them. This long-lasting and reflexive movement allows us to affirm that School Cartography is a consolidated field of research in the heart of Geography in Brazil. And being a consolidated field, it also allows the identification of recurrent discourses over time, where similar conclusions are repeated and confirmed, even if in terms of space and time, they are completely different. Thus, a first challenge is to overcome the recurrent discourses, that is, to advance in the conclusions and propose new keys for reading and research for the theme. On the other hand, the advancement of research and experiences in teacher training converge to another point of attention, curriculum policies and textbooks. Hence our second question: why don't textbooks change? If there are so many indications of advances in School Cartography and Teacher Training and, more recently, in curricular guidelines, what justifies the resistance of textbooks to maintain illustrative cartographic representations, disconnected from texts or only informative, without exploring the potential of this language. Since the textbook is our basis of investigation, our challenge with this work is to indicate some suggestions and directions so that future didactic materials can incorporate the advances achieved in school Cartography and, thus, overcome the discourses identified here and reach the potentialities of Cartography for the Teaching of Geography. Finally, our third and final question is: What does School Cartography understand by language? Thus, our challenge is to establish a dialogue between School Cartography and Linguistics in order to shed light on the discussion of the concept of language and, thus, propose new perspectives on the conception of cartographic language and its extension and importance for School Cartography.Item Apropriação e ritmanálise dos parques urbanos pelas práticas de lazer: análise comparativa do Parque Marcos Veiga Jardim - Goiânia - GO e do Parque Madureira Mestre Monarco - Rio de Janeiro - RJ(Universidade Federal de Goiás, 2025-03-24) Sousa, Flávia Kênia de Jesus; Maia, Carlos Eduardo Santos; http://lattes.cnpq.br/9080217578713778; Maia, Carlos Eduardo Santos; Batella, Wagner Barbosa; Costa, Carmem Lúcia; Silva, Lucineide Mendes Pires e; Oliveira, Ivanilton José deThis thesis is the result of a research that has examined the rhythm at which citizens currently use, consume, appropriate, and present themselves in urban parks through leisure practices. The methodological foundation of the investigation is a comparative analysis between Marcos Veiga Jardim Park – Goiânia, GO (PMVJ), located in an elite neighborhood, and Madureira Mestre Monarco Park – Rio de Janeiro, RJ (PMMM), situated in the suburbs of Rio de Janeiro. The study employed mixed methods, combining qualitative and quantitative elements, as it considered both measurable data, in explanatory terms, and non-measurable data, in descriptive-comprehensive terms. To achieve this, bibliographic, documental, and rhythmanalytic surveys were conducted, specifically utilizing Lefebvrian Rhythmanalysis at all stages of the research. Interviews with park users were also conducted, featuring both objective and discursive questions to, among other objectives, identify the profile and status of visitors' self-presentation; understand the meanings and perceptions they associate with the parks and how they present themselves in these public spaces; highlight the contradictions between the rhythms of these spaces and those of urban everyday life as a whole; investigate the daily and seasonal rhythmic variations in park appropriations and certain "natural" aspects; assess the benefits, expectations, and demands for these spaces; and question the perspectives and potentialities given by patrimonialization. It is stated that the main concepts worked on in the thesis are rhythms, daily life, urban parks, leisure and heritage, which are clarified based on other complementary concepts, such as citizenship, public space and clothing. The comparative analysis, based on the rhythm analysis of two parks, resulted in significant scientific advances by examining the differences and similarities in the social, cultural and environmental rhythms that define these spaces, as well as in their patrimonialization. Rhythmanalysis, proposed as the central method of this study, sought to understand how rhythms manifest themselves in different contexts and how they influence the experience of space-time. It proved to be extremely relevant for understanding rhythms in the comparison between Marcos Veiga Jardim Park and Madureira Mestre Monarco Park. Thus, it becomes a valuable tool for investigating other rhythms of life in future research.Item Avaliação da vulnerabilidade e riscos de contaminação em aquíferos cársticos no Cerrado(Universidade Federal de Goiás, 2024-12-09) Santos, Ana Karolyna Nunes Amaral dos; Momoli , Renata Santos; http://lattes.cnpq.br/4153268939426905; Cherem, Luis Felipe Soares; http://lattes.cnpq.br/8363108286297687; Faria, Karla Maria Silva de; Silva, Elaine Barbosa da; Lima, Cláudia Valéria de; Tibiriçá, Luciana GonçalvesKarst environments are characterized by areas of intense rock dissolution, which allows for the creation of various typical features such as sinkholes, resurgences, caves, and others. In Brazil, studies have been strengthening since the 1990s, resulting in scientific production that gradually expands into new areas and deepens knowledge of already studied regions. The identification and analysis of the distribution of these features are of great importance for the assessment of aquifer vulnerability. This study aims to identify, characterize, and zone the vulnerability and risk of groundwater contamination of the Bambuí karst aquifer in its western part. In this sense, the specific objectives are to present the state of the art of speleological studies in Brazil, identify karst features through available databases and the semi-automatic method of sinkhole identification, zone the intrinsic vulnerability to contamination of karst aquifers, and identify areas with the highest risk of groundwater contamination. Various methods were used to achieve the proposed objectives, ranging from a bibliographic survey in specific databases to the processing of satellite images and unmanned aerial vehicles. For sinkhole identification, the methodology presented in Carvalho Júnior et al. (2014) was used, and for vulnerability calculation, the EPIK method (Doerfliger et al., 1999) and COP method (Vías et al., 2002) were employed. The risk was calculated based on the methodology present in COST Action 620 (Zwahlen, 2004). The main results found that karst studies in Brazil are concentrated in the areas of Geology and Zoology, primarily produced in the Southeast region. The caves are predominantly located in the Southeast region of the Cerrado Biome, in the Neoproterozoic Cratons, mainly over the Bambuí Group. Regarding the semi-automatic method, 777 depressed features were identified, concentrated in the Paraopeba subgroup in the Lagoa do Jacaré Formation. Based on the sinkholes analyzed in high-resolution images, it was possible to calculate soil loss for the analyzed features, ranging from 663.47 to 4,241.68 tons. In the study of the Terra Ronca region, the analysis unit with the highest vulnerability was PETeR, with 9.9% of the area classified between high and very high vulnerability. In the comparison between methods, both identified high vulnerability areas within PETeR, with the EPIK method pointing to a larger extent of high vulnerability area due to not considering non-karst terrains in the area. In the analysis of vulnerability and risk of contamination for the western region of Bambuí, five vulnerability classes (Very High, High, Moderate, Low, and Very Low) were identified for both methods. The most vulnerable classes are over the Bambuí carbonate rocks, specifically on karst features (caves and sinkholes). The greatest risks are associated with activities such as mining, intensive agriculture, and the presence of Small Hydroelectric Plants (PCHs). It is noteworthy that conservation units proved to be territorial units that contribute to this conservation, as they help protect critical areas and mitigate the impacts of potentially contaminating activities. It is concluded that due to the natural fragility of the Bambuí karst aquifer, the zoning of natural vulnerability and contamination risk has proven to be an effective tool in the protection and conservation of karst aquifers, providing important support for the sustainable management of these groundwater resourcesItem Práticas avaliativas formativas em geografia no ensino médio: propostas para a formação do pensamento geográfico(Universidade Federal de Goiás, 2024-12-10) Rabelo, Kamila Santos de Paula; Cavalcanti, Lana de Souza; http://lattes.cnpq.br/8827112569170294; Cavalcanti, Lana de Souza; Alves, Amone Inácia; Pereira, Carolina Machado Rocha Bush; Souza, Vanilton Camilo de; Richter, DenisThe research addresses formative assessment as an essential tool for the development of geographical thinking in high school, within the context of the challenges faced by Geography education in Basic Education. The systematization of the theme is based on the observation that, although there have been theoretical and methodological advances in the field, assessment practices remain mostly traditional and regulatory, focusing on exams and standardized tests. The study argues that assessment for learning should be understood as an integral part of the teaching process, enabling continuous and formative analysis of the construction of geographical knowledge. The research is justified by the need to transform pedagogical practices, focusing on meaningful learning and student protagonism. The general objective was to understand how formative assessment can enhance the development of the ability to think geographically and to analyze spatial phenomena. The specific objectives included: identifying elements in official documents that demonstrate this formation; mapping existing theoretical approaches; analyzing teaching conceptions and practices; developing formative assessment proposals in collaboration with a basic education teacher; and systematizing these experiences. The methodology adopted was qualitative, with an interpretative and dialogical character, grounded in action research. The study was conducted in a public school in Anápolis, Goiás, with a teacher and third-year high school students. The procedures included bibliographic review, document analysis, classroom observations, interviews, and the implementation of collaborative didactic pathways using various assessment tools (mind maps, debates, journals, feedback, etc.). The results indicate that formative assessment, when intentionally integrated into the teaching process, significantly contributes to the development of geographical thinking, promoting autonomy, critical analysis, and the applied use of geographical concepts. However, difficulties were noted in breaking with traditional paradigms, due both to school culture and the scarcity of specific studies on assessment in Geography. Even so, the developed practices proved effective in promoting greater student development and conceptual deepening, especially when accompanied by continuous and personalized feedback. It is believed that formative assessment should be recognized as part of the pedagogical practice in school Geography, requiring teachers to have both theoretical-methodological mastery and sensitivity to deal with the practical challenges involved. The research highlights promising paths for future investigations into the construction of assessment instruments specific to the discipline, emphasizing the importance of an approach that articulates teaching, learning, and assessment in a critical and meaningful wayItem Ciberespaço e turismo religioso: ritmanálise nos cotidianos das santas(Universidade Federal de Goiás, 2025-03-25) Kelmer, Magno Angelo; Maia, Carlos Eduardo Santos; http://lattes.cnpq.br/9080217578713778; Maia, Carlos Eduardo Santos; Costa, Carmem Lucia; Balsan, Rosane; Cavalcanti, Lana de Souza; Castilho, DenisNhá Chica, Santa Paulina and Santa Dulce dos Pobres’ sanctuaries, respectively in downtown Baependi, state of Minas Gerais; Vigolo, in Nova Trento, state of Santa Catarina; and Bonfim, in Salvador, state of Bahia; began to streamline their exchanges in the virtual space, mainly by using online social media. These municipalities are very distinct as they belong to different geographical regions, but they do have things in common due to their religious tourist attractions. These religious attractions are linked to the lives and work of characters whose historically constructed representations need to be promoted, disseminated, marketed and consumed through the perspective of tourist activity. Nhá Chica, whose beatification occurred in 2013, is in the process of being canonized; Santa Paulina, canonized since 2002, was the first saint of Brazil; and Sister Dulce, the first saint actually born in Brazil, was the last one to be canonized, in 2019. This demonstrates the attention the Catholic Church has devoted to Brazil, a country which also concentrates the highest number of Catholics, even after the advancement of Protestantism, especially the Neopentecostal evangelicals in Brazil, and Islamism, in global terms. The sanctuaries and devotees’ social media pages that have those saints as a theme, in the specific case of Facebook, promote, disseminate, schedule religious events, receive donations, create virtual visits, that is, streamline the informational, symbolic and financial exchanges permeated by the use of technologies. However, it is not known how such followers, potential visitors of the tourist spaces, behave, interact, and change rhythms in these social media, as well as to what extent such practices influence the tourist consumption of the cities related to those saints. That leads to the question that guides this study: How are the social media pages of Nhá Chica, Santa Paulina and Santa Dulce dos Pobres used, considering their rhythmic alternations, and to what extent can these virtualities imply the consumption of tourist activities of the religious type in Baependi, Nova Trento and Salvador, impacting their daily lives and contributing to their polyrhythms? To this end, a cyber-etnography based on participating observation was held on the Facebook believers’ pages and the official pages of each sanctuary so as to capture the maximum relevant information about behaviors in online communities. On another front, fieldwork was carried out in different neighborhoods in times of routine movement and religious celebrations to find, or not, the power of influence of social media. During that time, the exercise of rhythmanalysis was present in the search to feel, identify and understand the rhythms of these daily lives. Although this is a tiny timeframe, given the constant dimension and technological advances that expand the possibilities of using cyberspace, this study indicated the remarkable presence of the use of social media as dynamizing elements of the tourist activity in these destinations of consolidated religious tourism in the countryItem Espraiamento urbano e planejamento integrado na Região Metropolitana de Goiânia: análise e cenários(Universidade Federal de Goiás, 2024-11-12) Naciff, Yordana Dias das Neves; Kneib, Érika Cristine; http://lattes.cnpq.br/2807145158226533; Barreira, Celene Cunha Monteiro Antunes; http://lattes.cnpq.br/1038300875963340; Barreira, Celene Cunha Monteiro Antunes; Hora, Karla Emmanuela Ribeiro; Firkowski, Olga Lucia Castreghini de Freitas; Lima, Leandro Oliveira; Ferreira, Nilson ClementinoUrban sprawl, characterized by the dispersed and disorderly expansion of cities, results in a series of challenges, such as the creation of urban voids, decreased population density, sociospatial segregation, and increased dependence on automobiles. These effects contribute to the formation of disconnected and difficult-to-manage regions, complicating integrated urban planning among the municipalities of the metropolitan area. Using the Metropolitan Region of Goiânia (RMG) as a case study, this thesis analyzes the impacts of urban sprawl on population and socio-territorial dynamics, economic factors, urban mobility, and environmental aspects. A systemic methodological procedure was proposed, based on General Systems Theory and the use of georeferencing tools, which allows for the analysis of interactions between various urban systems. The Dinamica EGO software was used to simulate urban expansion scenarios for the studied territory, aiming to develop territorial planning guidelines. The objective of this thesis is to identify and analyze the impacts of urban sprawl on the urban dynamics of the Metropolitan Region of Goiânia, with the goal of establishing guidelines and actions for integrated urban development in the RMG. To this, the thesis is divided into two parts, “defining the scene” and “ordering the scene”. The developed method validates the hypothesis constructed for this study and can be applied to other metropolitan regions using different urban variables. Among the contributions of this research are the application of General Systems Theory for urban analysis and the development of future urban expansion scenarios for the RMG. The results obtained underscore the importance of an integrated and systemic approach to mitigating urban sprawl, aiming to improve the quality of life in metropolitan regions and ensuring integrated urban development that is both socially just and environmentally sustainable.Item Contribuições à dinâmica geomorfológica recente na bacia do rio Javaés, Brasil Central(Universidade Federal de Goiás, 2024-10-29) Santos, Daniel Araujo Ramos dos; Cremon, Édipo Henrique; http://lattes.cnpq.br/7888258901938956; Cherem, Luis Felipe Soares; http://lattes.cnpq.br/8363108286297687; Cherem, Luis Felipe Soares; Marinho , Rogerio Ribeiro; Morais, Eduardo Souza de; Bayer , Maximiliano; Latrubesse , Edgardo ManuelThe morphodynamics of rivers are controlled by various external factors, whether natural or anthropogenic. In intertropical regions, Morphodynamic processes have been influenced by the expansion of land use conversion, transforming original vegetation cover into pastures and cultivation areas, as well as by the intensification of climate variability. These factors have triggered changes in fluvial discharge regimes, flooding, erosion, and sediment deposition. These alterations have been observed on the slopes of Brazilian savannas, while studies exploring their relationship with fluvial dynamics remain underexplored. The connection between slope and floodplain processes is particularly important for the Araguaia River Basin, which houses the world's largest fluvial island, Bananal Island. The objective of this thesis was to evaluate how hydrogeomorphological processes are influenced by climate change and land use, especially due to the intensification of agricultural activities in the eastern portion of the island, drained by the Javaés River. The methodology combined Remote Sensing approaches, machine learning techniques, statistical analysis, and field verification. LANDSAT images (1984-2022) were processed on the Google Earth Engine (GEE) platform to map flooded surfaces, water bodies, and sandbars. Supervised classification was applied to distinguish water areas, sandbars, and vegetation. Precipitation, land cover, and land use data were also analyzed using GEE. The Revised Universal Soil Loss Equation (RUSLE) was used to map sheet erosion rates in the sub-basins on the eastern edge of the island. Mann-Kendall (MK) and Sen’s Slope statistical tests were applied to identify temporal trends. The results indicate that climatic seasonality generates unimodal flooding cycles, with higher incidence in flat and basin-like areas. Paleoforms within Bananal Island control connectivity between flooded areas, affecting water flow and sediment deposition. The MK test indicates a reduction in flood occurrence between 1984 and 2022, particularly during the dry months and the beginning of the rainy season. A 57% (6.5 km²) increase in sandbar areas and a 39% (15.2 km²) reduction in water bodies were observed. Changes in the distribution of regional precipitation rates, combined with the expansion of agricultural activities, are contributing to increased sediment input, resulting in imbalances in the dynamics between erosion and deposition in the Javaés River, a tributary of the Araguaia River. The application of RUSLE revealed increased erosion rates, particularly in sub-basins where native vegetation has been replaced by degraded pastures. The highest soil loss rates were observed in the time series, reflecting the impact of intensified agricultural use. Protected areas, such as Bananal Island, demonstrated greater resilience and lower erosion rates compared to surrounding unprotected areas. These results underscore the importance of integrating management strategies to mitigate erosive impacts and preserve the geomorphological integrity of the region, particularly in contexts of increasing anthropogenic pressure and climate variability.Item Sertão negro das gerais: existências e vozes-narrativas de mulheres quilombolas, Minas Gerais(Universidade Federal de Goiás, 2024-03-25) Souza, Josy Dayanny Alves; Ratts, Alecsandro José Prudencio; http://lattes.cnpq.br/0348844638764982; Ratts, Alecsandro José Prudêncio; Silva, Givânia Maria da; Silva, Maria das Graças Silva Nascimento; Souza, Lorena Francisco de; Oliveira , Adriano Rodrigues deThe thesis “The Black Sertão of the Gerais” was developed based on a synthesized idea that considers the quilombo and quilombola women as the research theme and focus, specifically within the Quilombola Bem Viver territory of Vila Nova dos Poções, located in the rural area of Janaúba, Minas Gerais. The confluence of academic disciplines, walking through the sertões, participation in LAGENTE, engagement with Black Feminist Thought, and encounters with quilombola people during field research culminated in the discursive structure of this thesis: i) quilombo, territory, geography; and ii) quilombola women and geography. From this perspective, I aimed to elaborate a geographical approach in dialogue with the quilombo, focusing on the narrative voices of quilombola women. To achieve this goal, the following specific objectives were established: i) to understand the formation and organization process of the Quilombo Bem Viver of Vila Nova dos Poções through dialogue with elders and community leaders; ii) to present the contributions of Master's and Doctoral research in Geography on the quilombo/quilombola theme, as well as research focusing on quilombola women; iii) to analyze the intersections between central themes in Black Feminist Thought and those highlighted by quilombola women. Methodologically, a theoretical and epistemological review regarding the research theme and focus was conducted. Dissertations and theses produced in Brazilian postgraduate programs were significant for understanding the geographical thought on quilombo studies and quilombola women. Based on this perspective, a literature review on central themes supported by Black Feminist Thought—produced by Black and quilombola women—was carried out, alongside thematic semi-structured interviews. The understanding of the formation and organization of the Quilombo Bem Viver of Vila Nova dos Poções is associated with the memory and orality of the quilombola people, particularly their self-recognition as the Gurutubano people, due to their way of life established along the banks of the Gorutuba River. In the present day, certification from the Palmares Cultural Foundation (FPC) reinforces the Gurutubano people's self-definition as quilombola. Throughout the research journey and established dialogues, understandings were constructed regarding the inseparability of religious rituals and cultural rites, with particular emphasis on religious celebrations and the Rodas de Batuque. The sense of belonging demonstrated profound ties to water, especially through ways of life related to the Gorutuba River and Lagoa Grande. In all the central themes presented in the thesis, the narrative voices and existences of quilombola women were evoked with the strength of their words and presence. In this context, I emphasize education as an ancestral movement within the quilombo. The women of the Quilombo Bem Viver of Vila Nova dos Poções have built an ancestral movement that now inspires the territory's struggles for the implementation of Quilombola School Education based on a sense of belonging.Item Fazendo Arte na Geografia Escolar: O lugar-Cerrado nos Anos Iniciais do Ensino Fundamental(Universidade Federal de Goiás, 2024-03-27) Azevedo, Mariângela Oliveira de; Alves, Adriana Olívia; http://lattes.cnpq.br/2629325348519209; Alves, Adriana Olívia; Ribeiro, Miriam Bianca Amaral; Olanda, Elson Rodrigues; Queiroz, Fabiana Rodrigues Oliveira; Morais, Eliana Marta Barbosa deThis research was based on desires present in our teacher training - for an educational action linked to the transformation of reality, permeated by teaching-learning processes with a view to an emancipatory education. In turn, these concerns have led me to school geography, a field in which I work as an elementary school teacher in the Early Years. From this experience, convergences emerge with academic-scientific production in the field of geography teaching and learning, which has long pointed to the need to appropriate teachinglearning practices with more meaning and significance and new languages, advancing in the observation of mechanistic methodologies that are disconnected from reality. These arguments led us to the initial problematizations for this research, through which we set out to think about teaching and learning in School Geography, indicating Art as a creative language for the construction of geographical knowledge in the classroom. To this end, we approached the Cerrado as a theme - essential and urgent geographical knowledge to be addressed in elementary school. The Cerrado is currently suffering the direct impact of neoliberalism, ideologized in the service of hegemonic interests, especially represented by economic activities aimed at agribusiness. The impact of this condition is multidimensional and requires interventions that permeate the classroom from the earliest school years, in order to form a critical awareness of the issue. In order to bring the complexities of the Cerrado closer to the teaching and learning of Geography in the Early Years of Primary School, our work proposed conceptualizing place-Cerrado, arguing in favour of place as a geographical concept that materializes the Cerrado in a meaningful way for students at this stage of education, as well as providing critical analyses of the world as a whole in an integrative way. The qualitative research consisted of investigative steps towards the goal of analyzing how teaching and learning about the Cerrado in school geography, using art as a creative language, can lead to emancipatory geographical knowledge in the Early Years. These steps were taken through the organization of three sections, the first two being a theoretical-methodological discussion about the relationship between the Cerrado, geographical place, Art and education, and the third dedicated to the analysis of a proposal for teaching and learning about the Cerrado in the Early Years of Primary School, a project carried out in a municipal public school in the city of Goiânia, with 5th grade students, in line with an action-research modality. Based on the lessons, we were able to draw up theoretically-based analyses of how the Cerrado place, associated with art as a creative language, could contribute to the construction of emancipatory geographical knowledge in the Early Years, a thesis presented by this research. In the methodological process, we used class diaries, analysis of activities and interviews as tools for analyzing the data. The entire discussion was based on the assumptions of historicaldialectical materialism as a method of analysis. As a result, the research has shown contributions that advance the need for critical teaching and learning and has been configured as a possible praxis, in School Geography, in approaching the Cerrado theme in an emancipatory way.Item Oeste Goiano: gênese, formação e dinâmica da rede urbana(Universidade Federal de Goiás, 2024-08-28) Oliveira, Érika Munique de; Castilho, Denis; http://lattes.cnpq.br/4271473426990028; Castilho, Denis; Olanda, Elson Rodrigues; Bessa, Kelly Cristine Fernandes de Oliveira; Druciaki, Vinícius Polzin; Santos, Iann Dellano da SilvaWhen considering the context of formation of West Goiano and the rearrangements in the regional space, it becomes crucial to understand the factors that influenced the formation and dynamics of the urban network in this region. In view of this, this research analyzes the historical processes that led to urban formation and structuring, as well as the redefinitions of centralities, with an emphasis on three centers: Anicuns, São Luís de Montes Belos and Iporá. The methodological procedures were based on bibliographical research, documentary analysis in the Historical Collections of the State of Goiás, the Museu das Bandeiras and the Fundação Frei Simão Dorvi. Documents published by the Brazilian Institute of Geography and Statistics (IBGE) were consulted, including the demographic (1920-2022), agricultural (1940-1996), industrial, commercial and services (1970-1980) censuses, studies on Regions of Influence das Cidades (1993, 2007 and 2018) and the encyclopedia of Brazilian municipalities. Planning collections in Goiás (1961-2006) from the Mauro Borges Institute of Statistics and Socioeconomic Studies (IMB) were also analyzed, as well as the creation of tables, graphs and thematic maps that show the results obtained. The narrative unfolds into four chapters. We defend the thesis that, among all the spatial strategies implemented by the State in West Goiás, the construction of the GO-060 highway played a central and decisive role in the region's participation in internal and external markets, and in the rearrangement of centralities, redefining the socioeconomic configuration and space of the region. The establishment of the road axis facilitated the advancement of capitalist production activities, which resulted in an increase in economic activity and the redistribution of demographic flows to the region studied, enabling the emancipation of several districts between the 1950s and 1970s. As a result , the municipalities of São Luís de Montes Belos, Iporá and Anicuns experienced an emblematic process of urbanization in the following decade, becoming privileged locations for the installation of companies dedicated to the production and processing of milk and slaughterhouses. As a result, these cities became important centralities throughout the second half of the 20th century. This trend, however, did not continue into the following century. While São Luís de Montes Belos and Iporá maintained their positions as prominent regional centers, Anicuns did not follow this movement. This scenario is the result of the strategic expansion of services and infrastructure promoted by the State and entrepreneurial agents, aimed at the two urban centers strategically located along GO-060, the main axis of circulation and flow of agricultural production in the region. This means that the way in which the State and economic agents used and continue to use this highway is a fundamental element for understanding the dynamics of the urban network in West Goiás.Item Geoconservação e proposta de uso sustentável do patrimônio paleontológico do Norte do Estado do Tocantins e Sudoeste do Estado do Maranhão(Universidade Federal de Goiás, 2024-10-23) Lopes, Raylon da Frota; Candeiro, Carlos Roberto dos Anjos; http://lattes.cnpq.br/2584676055987613; Lima, Cláudia Valéria de; http://lattes.cnpq.br/5929601393924549; Lima, Cláudia Valéria de; Costa , Ana Cláudia Dantas da; Machado, Carlos Augusto; Pereira , Bruno Miguel Claro; Sarges, Roseane RibeiroIn the central-northern region of Brazil, in the northern state of Tocantins and the southwestern state of Maranhão, there are known fossiliferous outcrops with notable scientific importance. These occurrences date from the Permian to the Cretaceous of the Intracratonic Sedimentary Basin of Parnaíba and require geoconservation strategies for their proper sustainable use and management. Although scientific knowledge has already been produced about the paleontological heritage present in the study area, until now no research had been conducted with a geoconservation approach including inventory, quantification of values and potentials for use, and vulnerability for the geosites in this region.The general objective of this work is to characterize the paleontological heritage originating from the Paleozoic and Mesozoic of the northern region of Tocantins and southwestern Maranhão in its physical aspects and social relevance. To achieve the proposed objective, a bibliographic survey and fieldwork were carried out to prepare the inventory of the fossiliferous outcrops in the studied area. In the quantification of the values and potentials for use of the outcrops, the Geossit platform, developed by the Geological Survey of Brazil, was used. The inventoried fossils consist of shark somatofossils, gymnosperm trunks, and mineralized ferns, sauropod and theropod ichnofossils, and indeterminate leaf molds. For the quantitative assessment, only geosites were considered, namely: the geosites comprising the Natural Monument of Fossilized Trees of Tocantins in Filadélfia (Permian); the geosite containing theropod dinosaur footprints in Fortaleza dos Nogueiras, Maranhão (Triassic); and the geosite containing sauropod dinosaur footprints in Itaguatins, Tocantins (Early Cretaceous). Overall, the geosites obtained scientific value and potentials for educational and tourist use ranging from moderate to high, and a low risk of degradation for the outcrops of the Natural Monument of Fossilized Trees of Tocantins, medium for the theropod footprints, and high for the sauropod footprints.The studied locations have the potential for geoeducational and geotouristic activities, which can contribute to the social and economic development of the region. However, each geosite must be utilized considering specific strategies that respect their potentials and limitations.Item Imaginário e memória do patrimônio histórico edificado de Goiânia: mudanças e permanências da fundação aos dias atuais(Universidade Federal de Goiás, 2024-10-31) Soares , Sueli Souza de Oliveira; Silva , Valéria Cristina Pereira da; http://lattes.cnpq.br/5755146027054522; Silva , Valéria Cristina Pereira da; Oliveira, Adriana Mara Vaz de; Deus, João Batista de; Barreira , Celene Cunha Monteiro Antunes; Barros, Juliana Ramalho“Imagination and Memory of the built historical heritage of Goiânia: changes and permanence from the foundation to the present day” is the result of an accurate exercise of looking at the city in search of symbols, meanings, values and representations present in urban images. We outline our reflections around the reading of the built historical heritage from two different points of view, from the perspective of current views and from the perspective of historical views. In reading the heritage from these different perspectives in different temporalities, we grasp the meanings through fragments of the city, monuments and places of memory, we observe the imaginary, the desires and the feelings influenced by personal trajectories. In this exercise, we find that the built historical heritage establishes itself as one of the anchors of the representation of Goiânia, capable of engendering a relationship between imagination and memory. We built this trajectory in order to meet the main challenge of this thesis, which is to investigate the interface between the historical built heritage of Goiânia (GO) and the imaginary of modernity constructed in the early days of the city founded in 1933. The approach to the theme is multidisciplinary, in an interface zone between Humanist Geography, History and Architecture and Urbanism, in light of the imaginary of the city. The work seeks an innovation from a methodological point of view, which has at its core the subject-object relationship, based on the perception of the city. On the one hand, it is in tune with the theoretical approach that points out paradigms on theories of the urban imaginary and, on the other, it proposes an approach to the theme of urban memory, based on the reading of the historical built heritage of Goiânia, where not only the building, its forms and characteristics of its architectural style will be read.Item A formação profissional continuada e o ensino de geografia nos anos iniciais em uma perspectiva histórico-cultural(Universidade Federal de Goiás, 2022-10-14) Moraes, Ismael Donizete Cardoso de; Souza, Vanilton Camilo de; http://lattes.cnpq.br/1374656969635983; Souza, Vanilton Camilo de; Sforni, Marta Sueli de Faria; Moraes, Loçandra Borges de; Cavalcanti, Lana de Souza; Morais, Eliana Marta Barbosa deThe continuing education of teachers has been constituted through multiple theoretical approaches and methodological paths. Specifically, in this work, theoretical-methodological aspects of the continuing education of pedagogues were addressed, considering the challenges to teach geography in the early years. Thus, the development of the research had as reference the continuing education of pedagogues, organized from the practical professional problems , from the cultural-historical theory and from the concepts of landscape, place, city and urban. In this sense, the research problem is how continuing education, imagined and thought from the practical professional problems, can help teachers in the early years to appropriate fundamental aspects of geography content and plan classes in a way that students go beyond the limits of classification and mechanical memorization of contents. Following this proposition, the general objective is to understand how continuing education focused on professional problems, based on historical-cultural theory, helps teachers to appropriate geographic and didacticmethodological concepts and develops a teaching proposal based on authorship and in the autonomy of teaching practice. To approach this objective, we specifically seek: to analyze the importance of continuing education for the development of geographical knowledge by pedagogues who work in the early years of Elementary School; identify and enhance the influence of the place and the landscape (of the city of Barra do Garças) in the teaching and study of geographical contents in the early years of Elementary School; verify the appropriation of knowledge and geographic thinking in the planning and development of the plan in the classroom; investigate the mediating processes in the elaboration and execution of the teaching proposal. Thus, the methodology has primacy in the qualitative aspects parameterized by the collaborative attributes of action research. Based on this perspective, observation, narratives and plans developed by the teachers are used as investigation procedures. The study of the concepts of place, landscape, city and urban, organized from the problematization, systematization and synthesis, didactic steps developed by Cavalcanti, and the elements of didactic mediation of Davydov, from the general to the particular, from the collective to the individual, and from the empirical to the theoretical-conceptual, they are essential in the development of research. The results point to an advance in the domain of concept s, perceptible in the teachers’ speeches, in the narratives, in the plans re-elaborated during the course and in the development of the plan in the classroom by one of the teachers. In the re-elaborated plans and in the didactic action, it is possible to perceive an advance in the harmony between the concepts of landscape and place with the objectives and contents. Also, the relationship between the concepts of place and landscape with the concepts of urban and city became more evident, as well as the elements of didactic mediation of geographic contents.Item Estimativa de parâmetros biofísicos no Cerrado, em paisagens agrícolas e nativas, a partir de sensores imageadores embarcados em plataformas aéreas não tripuladas(Universidade Federal de Goiás, 2024-04-12) Lima, Gabriella Santos Arruda de; Ferreira, Manuel Eduardo; http://lattes.cnpq.br/4498594723433539; Ferreira , Manuel Eduardo; Barreira, Sybelle; Ruiz, Luis Fernando Chimelo; Ferreira Júnior, Laerte Guimarães; Bueno, Guilherme TaitsonIn recent years, Unmanned Aerial Vehicles (UAVs), identified here by the acronym UAV, for Unmanned Aerial Vehicle, have rapidly advanced remote sensing systems, allowing for effective assessment of agricultural crops and natural areas through the processing and integration of field data and various sensors embedded in UAVs. This study addresses the scarcity of biomass and carbon estimates in integrated livestock and crop systems (iLP) and highlights the use of onboard sensors of unmanned aerial vehicles (UAVs) as an efficient and cost-effective method for acquiring precise remote sensing data. In this thesis (comprised of three articles), the first research was conducted in an experimental iLP area of Embrapa Rice and Bean, in the core area of the Goiás Cerrado, employing high-resolution multispectral aerial images to estimate the relationship between vegetation indices (VIs) and carbon stock in an upland rice field intercropped with Brachiaria, a species of exotic grass from the Brazilian Cerrado ecosystem. The results indicated that VIs incorporating near-infrared (NIR) exhibited a stronger correlation with biomass than those using only visible band information. Regression models successfully predicted biomass and carbon stock at different stages of the iLP cycle. Maps were generated showing the spatial and temporal distribution of biomass, emphasizing the advantages of using drones and multispectral sensors in this type of analysis. The second study organized in this research, also conducted in the company's experimental area in Goiás, explored the estimation of evapotranspiration (ET) in different crops and soil coverages through multispectral images captured by drones. The method employed - SAFER (Simple Algorithm for Evapotranspiration Retrieving) - showed good agreement for ET between drone and satellite data, highlighting its applicability and flexibility, without depending on satellite images affected by clouds or monitoring towers in the field. The study highlights the importance of integrated agricultural practices to better manage water resources and minimize negative impacts on the Cerrado's hydrological system. Lastly, the third study investigated the use of multispectral sensors onboard UAVs to monitor nitrogen status in agricultural crops, specifically in irrigated rice cultivation. The results demonstrated that aerial sensors performed well in estimating agronomic parameters related to nitrogen status, such as total above-ground biomass, leaf nitrogen content, and leaf area index, at different phenological stages of the rice cycle. This method shows promise in overcoming the limitations of satellite cloud cover and providing greater coverage with shorter operating times, compared to field optical sensors (non-imaging). These studies highlight the relevance and effectiveness of using drones and multispectral sensors for various agricultural applications, ranging from carbon and biomass estimation in integrated systems to monitoring evapotranspiration and nutrient status in specific crops, thereby contributing to a more sustainable and efficient management of the natural resources of the Cerrado.Item O estudo dos componentes físico-naturais e o desenvolvimento do pensamento geográfico no ensino médio(Universidade Federal de Goiás, 2024-06-07) Xavier, Maria Pereira da Silva; Morais, Eliana Marta Barbosa de; http://lattes.cnpq.br/3615558165803518; Morais, Eliana Marta Barbosa de; Pereira, Marcelo Esteban Garrido; Evangelista, Armstrong Miranda; Souza, Vanilton Camilo de; Moraes, Loçandra Borges deSchool Geography in High School must be developed with the intention to contribute with the citizen formation of the young student. From this understanding, the present work aims to understand how the study of physical-natural components, from the theme of flooding, can contribute to the development of Geographical Thinking in young students of High School, favoring the construction of scientific concepts and the development of conceptual-theoretical thinking. And seek to contribute with this demand from overcoming a problem present in High School, limited to the little interest that this stage of Basic Education arouses in young students. With this purpose, Geography Teaching was inserted into the debate, based on the study of physicalnatural components, as we understand that School Geography has the specificity of analyzing geographical space area, the living space of the young student, and meets the necessary conditions to be a meaningful Teaching for this young person. To achieve the proposed objective, we resort to a theoretical basis that covers different fields of knowledge, among which we highlight, in the field of education Shulman (2014), in the field of psychology Vigotski (2009), in the field of geographic science Santos (1997 , 2012), in the field of Geography Teaching Cavalcanti (2002, 2005, 2019, 2021), Roque Ascensão (2009), Morais (2011), Morais and Roque Ascenção (2021) and Callai (2001, 2010, 2015) and to understand urban flooding, we consulted Tucci (2004, 2007). This is qualitative research and presents characteristics of critical interpretative tradition research. It was developed with the contribution of four Geography teachers who work in High School, in private and public schools, in the city of Floriano/PI. Through questionnaires, interviews, class observations and workshops, we sought to know the pedagogical practice of these teachers, their knowledge regarding the Geography teaching, the physical-natural components and floodings, as well as how these contents are taught in the classroom. In the development of the thesis, it was possible to note that Geography Teaching, when working the physicalnatural components, in the perspective of formation of scientific concepts and theoretical-scientific thinking, contributes to the development of Geographical thinking, thus becoming a meaningful knowledge to young High School students. We have seen that when are worked in the classes themes which take into consideration the daily life of students, their background knowledge mobilizing theoretical-methodological framework (structuring concepts, principles and methods) developed by geographic science, the teacher can contribute to the construction of scientific concepts and with the conceptual theoretical development of young students. The contribution of this study involves the connection made between the importance of High School in the training of young students and the importance of Geography Teaching, in terms of the formation of scientific concepts and the development of a specific way of thinking, which allows them to understand their living space, favoring their citizen activity. And also, by bringing up issues related to teacher work, which contribute to Geography Teaching being guided taking the development of geographical thinking as reference.Item Proposta metodológica para mapeamento da vulnerabilidade à perda de solos: estudo de caso da bacia hidrográfica do Rio Marataoan, Piauí(Universidade Federal de Goiás, 2024-02-05) Leal, Janaira Marques; Aquino, Cláudia Maria Sabóia de; http://lattes.cnpq.br/0090245396610980; Oliveira, Ivanilton José de; http://lattes.cnpq.br/4172719252263913; Oliveira, Ivanilton José de; Romão, Patrícia de Araújo; Silva, Gladis de Fátima Nunes da; Valladares, Gustavo Souza; Nascimento, Diego Tarley FerreiraThe general objective of this research is to present a methodology for mapping vulnerability to soil loss, improving the proposal by Crepani et. al (2001), by replacing the “dissection index” with the parameter “shape of the slopes” (overlap of horizontal and vertical curvatures) and the “altimetric amplitude” with the HAND model - Height Above the Nearest Drainage. As specific objectives, the work aims to characterize the geoenvironmental aspects of the Marataoan River watershed (geology, geomorphology, hydrography, land use and cover, climate and soil associations); discuss the theoreticalmethodological assumptions of Crepani et.'s methodology. al (2001); test and evaluate the proposed adaptations regarding geomorphological parameters. As main results, an analysis of the vertical dissection of the study area was carried out through the application of the HAND algorithm, observing that the class that stands out in the area is the moderate one, with 40.9%, followed by the low vulnerability class, with 36.3%. Regarding the use of Vertical and Horizontal Curvatures in the analysis of water flow and its relationship with the intensity of rain erosion, the area highlighted the low and high vulnerability classes, being 51.3% and 35.5% of the total surface, respectively. It was observed that the proposed analysis model, integrating new geoenvironmental variables, characterized in a more coherent way the possible areas of material loss by linear erosion, in convergent areas with flow concentration, and by laminar erosion, in divergent areas with dispersion of flow. Therefore, the parameters used to adapt the methodology of Crepani et al. (2001) proved to be of fundamental importance in the relationship between the environment and occurring erosion processes. Thus, the present research is relevant to support the analysis of the erosive vulnerability of the Marataoan river basin, in order to guide interventions by public authorities with a view to sustainable development both in the study area studied here and in other areas to apply the same method.Item Índice de Privação Territorial em Unidade de Conservação (IPTUC): análise integrada do território e da saúde de comunidades rurais que coexistem com unidades de conservação(Universidade Federal de Goiás, 2024-02-06) Mendonça, Daniella Souza de; Barros, Juliana Ramalho; http://lattes.cnpq.br/3897963687114981; Barros, Juliana Ramalho; Costa, Kênia Gonçalves; Souza, Lucas Barbosa e; Chaveiro, Eguimar Felicio; Souza, Lorena Francisco deThe connection between territory and health is an issue that requires a multidimensional research approach and has been increasingly debated by studies carried out along the lines of Health Geography. Understanding the impacts of implementing Conservation Units in already inhabited territories is essential for analyzing the health of local populations and understanding how territorial management can make a community vulnerable or increase its strength. This research has as its main objective the creation of an index capable of analyzing the territorial deprivation of rural communities that resid in territories converted into Conservation Units, in this case, in the APA and PARNA Cavernas do Peruaçu. The research is composed by three complementary scales and times that were worked on in accordance with specific objectives, namely: the investigation of the historical process in which the occupation of the region (Peruaçu river basin) where the studied communities are located took place; the analysis of how communities are understood in the Management Plan of the National Park and APA Cavernas do Peruaçu, bringing a legal approach in relation to the use and possession of the territory and its possible consequences for the communities; the characterization of the territory and communities of Fabião I and Retiro, bringing a perspective of what is consolidated in the throbbing daily life; and the creation of the Territorial Deprivation Index in Conservation Units (IPTUC). This case study was based on bibliographical research, document analysis, primary data collecting, descriptive observation, interviews, descriptive and conclusive statistics. In the interviews and application of the semi-structured questionnaire, study variables were investigated, such as: education level, income, age, family composition, housing quality, eating habits, environmental conditions, access to health/basic sanitation, belonging, power ratio, coexistence with the drought and finally the respondents' relationship with the Cavernas do Peruaçu Park and Environmental Protection Area. The thesis is that the result of the Territorial Deprivation Index in Conservation Unit (IPTUC) in the Retiro community will present lower results in relation to the Fabião I community due to the legal use and restrictive territorial management imposed after the creation of PARNA Cavernas from Peruaçu.Item Do consenso da fome à soberania alimentar: políticas públicas e produção de alimentos saudáveis na região metropolitana de Goiânia (GO)(Universidade Federal de Goiás, 2024-03-22) Peixoto, Ângela Maria Martins; Oliveira, Adriano Rodrigues de; http://lattes.cnpq.br/1909084450648691; Oliveira, Adriano Rodrigues de; Mendonça, Marcelo Rodrigues; Coca, Estevan Leopoldo de Freitas; Cruz, Fabiana Thomé da; Furtado, Ariandeny Silva de SouzaThe present study addresses as a central theme the analysis of public food acquisition policies, focusing on the relationship between food production, institutional markets and short circuits in the Metropolitan Region of Goiânia (RMG) in the light of a geographical reading. The objective of the research is to understand the role of institutional markets for the promotion of two short marketing circuits and for the construction of food sovereignty in Brazil, with the territorial cutback being RGM in the period from 2003 to 2020. The hypothesis is that the Brazilian food system is controlled by food empires that prioritize the production of commodities and industrialized/ultra-processed foods, promoting the subordination of land income from peasant agriculture, the rise of large supermarket chains and the standardization of eating habits, which contributes to the loss of dietary diversity and the maintenance of hunger. For this, the methodological procedures consisted of bibliographical research, secondary data collection from IBGE, CONAB, CEASA-GO, Rede Penssan; carrying out fieldwork in the Metropolitan Region of Goiânia (RMG), and carrying out an online survey on the food purchasing habits of Brazilians. The class nature of the State is adopted as an assumption, which is made up of power blocs, in favor of the dominant classes. The evaluation of the implementation of public food acquisition policies revealed significant results for achieving food and nutritional security and for the commercialization of peasant production through institutional markets. However, these changes were limited to government policies, which did not guarantee the maintenance of the advances achieved in combating hunger with the rise of neoliberalism. Thus, with the political, social, and economic crisis that took place since 2016, the COVID-19 pandemic in 2020 and the dismantling of public social policies, such as the PAA, Brazil returned to the Hunger Map, causing 33 million Brazilians to live with hunger again, in a country that leads the production of agricultural commodities on the world market. This research highlights the correlation between the State and the founding elements of food production, circulation, distribution, and consumption, highlighting the disparities in relation to subsidies allocated to peasant agriculture and agribusiness. In effect, the production of commodities is prioritized over food production, through a production and circulation infrastructure promoted by the State. The constitution of this hegemonic food system is also marked by the expansion of food empires, promoting food standardization with the dissemination of industrialized and ultra-processed products and the subordination of peasants and consumers in the marketing and consumption processes. Such aspects highlight the Hunger Consensus. However, despite the predominance of long marketing circuits and the substantial increase in hunger, field observations have shown that it is possible to rethink this food system and promote short marketing circuits by bringing farmers and consumers closer together. Thus, counter-hegemonic actions are crucial for strengthening food sovereignty, with the valorization of peasant agriculture and agro-ecological production, guaranteeing access to healthy food in the countryside and in the city.Item Erosão quaternária nas superfícies escalonadas do Brasil Central(Universidade Federal de Goiás, 2023-12-15) Caminhas, Francielle Gonçalves; Siame, Lionel Louis; Bueno, Guilherme Taitson Bueno; http://lattes.cnpq.br/1585424190030655; Bueno , Guilherme Taitson; Cherem , Luis Felipe Soares; Lima, Claudia Valeria de; Zancopé , Márcio Henrique de Campos; Leite, Marcos EsdrasThe dynamic process of denudation renews and sculpts landscapes, reflecting the interplay between terrain lowering (downwearing) and the lateral retreat of slopes (backwearing). This interaction occurs through cycles of erosion (degradation) and deposition (aggradation), shaping the relief. This study aims to assess denudation, measured by cosmogenic nuclide beryllium-10, and its impact on the geomorphological evolution of the stepped surfaces in the Serra Geral region of Goiás, Brazil. The adopted methodology included: 1) geomorphological compartmentalization using morphometric analysis and remote sensing; 2) the selection of 20 representative hydrographic basins for the collection of fluvial channel sediments; 3) the collection of samples from surface formations at the top of a planation surface (Intermediate Surface); 4) the analysis of beryllium-10 (10Be) concentration in the collected materials, conducted at the ASTER AMS laboratory (CEREGE), Université Aix-Marseille, to determine the denudation rates of the sub-basins that flow into the Paranã and Tocantins rivers. Central to our hypothesis is the idea that a complex denudational dynamic shapes the evolution of the Serra Geral de Goiás and the incorporated surfaces, influenced by factors such as mass movements, fluvial incision, and aggradation zones. We identified four distinct regional compartments, characterized by differences in relief, pedological cover, and vegetation: (I) Central Plateau; (II) Intermediate Surface (divided into Remnant and Dissected); (III) Paranã Gap; and (IV) Escarpment, Mountainous Complex, and Relictual (Veadeiros Plateau; front of the Serra Geral Cuesta and relictual reliefs). The first three units were correlated with the South American surfaces, South American I, and South American II, according to Valadão (2009). Through the measurement of 10Be in fluvial sediments, it was observed that denudation rates are higher in basins linked to the escarpment of the Serra Geral, with a median rate of 87±9 m Myr-1 and variations from 43±4 to 196±61 m Myr-1 . This variation suggests greater instability in certain sectors, possibly due to the prevalence of mass movements and the remontant fluvial incision that forms festoons in the escarpment and captures watercourses from the São Francisco basin. The median denudation rate for the basins of the Intermediate Surface is 25±2 m Myr-1 , ranging from 11±1 to 44±4 m Myr-1 . The median denudation rate for the top of this surface was 11 m Myr-1 , suggesting greater stability in the planed sector, while the more aggressive hydrographic network of the Paranã rivers intensifies the excavation of the surface. For the Central Plateau, the estimated rate is 9±1 m Myr-1 . These data indicate a horizontal retreat of the escarpment to the east at a rate of 78±10 m Myr-1 (N-S extension). The vertical denudation difference between the Central Plateau and the Intermediate Surface is 16±3 m Myr-1 , indicating that the planation of the latter began between the Middle and Upper Miocene (8 to 18 Myr) and that the surfaces are reducing at different intensities. The Central Plateau presents an average excavation rate of 13±1 m Myr-1 , while the Intermediate Surface and the Paranã Gap show average rates of 32±1 m Myr-1 and 53±5 m Myr-1 , respectively. The consistent denudation, as evidenced by isotopic denudation rates, highlights the Intermediate Surface as a pediplain of prolonged exposure, which integrates into the regional geomorphological dynamics, with a median denudation rate of 25 meters per million years (m Myr-1 ), following the escarpment retreat. The stepped surfaces of this region are shaped by structural, climatic, and hydrogeological factors. Mass movements and wet areas are fundamental, as they influence denudation rates and contribute to the conservation of the geomorphological system. On surfaces with less incision and more resistant rocks, planation prevails, resulting in reduced denudation rates. On the other hand, on the Intermediate Surface, characterized by more aggressive incision and drainage, denudation rates are moderate to high. Fluvial erosion is directed by two main erosive fronts: one acts on the Intermediate Surface, under the control of the basal surface of the Paranã, and the other progresses over the plateaus from the escarpment, intensified by mass movements. The latter are crucial for the high denudation rates, while wet areas play a significant role in the aggradation process and sediment retention, acting as barriers to denudation on the Intermediate Surface and favoring geomorphological stability and river permanence.
