In this context, lichens stand out as sensitive biomonitors of environmental change. This study aimed to analyse the relationship between the recurrence of forest fires, landscape units, and the diversity of lichen communities in the Serra de Itabaiana National Park (PARNASI) between 1985 and 2024. The methodology integrated data from MapBiomas Fire 4.0, analysis of landscape units, climatic variables, field surveys, lichen identification, alpha and beta diversity indices, and correlation analysis between fire frequency and lichen diversity. The results showed that fire recurrence was concentrated in more open areas and during periods of lower rainfall, indicating the influence of climatic seasonality on fire dynamics. Burnt areas exhibited reduced alpha diversity and lower specimen richness, whereas beta diversity increased as a result of species turnover between burnt and unburnt areas. A negative correlation was observed between fire frequency and lichen diversity, confirming the potential of lichens as bioindicators of environmental degradation and changes in the landscape dynamics of PARNASI. 2026-04-13T00:00:00Z https://ri.ufs.br/jspui/handle/riufs/25474 Título: Feiras da agricultura familiar conectam o campo e a cidade no sul sergipano Autor(es): Santos, Vanessa Modesto dos Abstract: The aim of this thesis is to analyze the effects of the public policy that established the Family Farming Market, the contribution of local public management to maintaining this marketing territory, as well as the changes observed in rural establishments and their impact on food and nutritional security. The municipalities of Cristinápolis, Indiaroba, Itabaianinha, Santa Luzia do Itanhy, and Umbaúba—located in the southern territory of the state of Sergipe—were selected as the spatial scope due to their strong agricultural practices. As methodological procedures, the research began with a theoretical review focused on public policies related to family farming, followed by a review of the categories of territory, agricultural production, commercialization, and consumption. Subsequently, documentary analyses of secondary data and information were carried out, addressing historical and socioeconomic dimensions, agricultural production, and public policies aimed at family farming. Between 2023 and 2025, the procedures mainly involved field research with farmers/vendors and consumers at the Family Farming Markets, as well as technical representatives from municipal departments responsible for organizing the logistics of these fairs. Visits to rural family establishments were also conducted, including exploratory interventions and interviews based on the snowball sampling technique, along with the use of field diaries and photographic records. The results of this thesis highlight the social, cultural, and economic relevance of Family Farming Markets in the southern municipalities of Sergipe. In addition to generating income for farming families that sell in these territories, the markets have contributed to the diversification of food crops in rural establishments, which is essential for the Food and Nutritional Security of farmers and vendors. Regarding the maintenance and strengthening of this marketing territory, the study reveals the effects of different actions and the support provided by municipal management within the studied area. It is concluded that effective public actions and the interrelations between producers and consumers strengthen the advancement and consolidation of agroecological practices, the empowerment and socioeconomic reproduction of family farmers, and the cultural rootedness of this marketing territory.; El objetivo de esta tesis consiste en analizar los efectos de la política pública que instituyó la Feria de la Agricultura Familiar, la contribución de la gestión pública local en el mantenimiento de este territorio de comercialización, así como las transformaciones ocurridas en los establecimientos rurales y su repercusión en la seguridad alimentaria y nutricional. Como recorte espacial, se seleccionaron los municipios de Cristinápolis, Indiaroba, Itabaianinha, Santa Luzia do Itanhy y Umbaúba, que conforman el territorio sur del estado de Sergipe, debido a su relevancia en la práctica agrícola. En cuanto a los procedimientos metodológicos, se inició con una revisión teórica orientada al estudio de las políticas públicas vinculadas a la agricultura familiar, seguida de una revisión de las categorías de territorio, producción agrícola, comercialización y consumo. Posteriormente, se realizaron análisis documentales de datos secundarios e informaciones relativas a las dimensiones históricas y socioeconómicas, a la actividad agropecuaria y a las políticas públicas dirigidas al sector de la agricultura familiar. Durante el periodo comprendido entre 2023 y 2025, los procedimientos se enfocaron principalmente en la realización de investigaciones de campo con agricultores/as, feriantes y consumidores en las Ferias de la Agricultura Familiar, además de entrevistas con representantes técnicos de las secretarías municipales encargadas de la organización logística de dichas ferias. Asimismo, se llevaron a cabo visitas a los establecimientos rurales de las familias agricultoras, con intervenciones exploratorias y entrevistas basadas en la técnica snowball, haciendo uso del diario de campo y de registros fotográficos. Los resultados de esta tesis ponen de manifiesto la relevancia social, cultural y económica de las Ferias de la Agricultura Familiar en los municipios del sur de Sergipe. Además de generar ingresos para las familias agricultoras que comercializan en este territorio, se observó una diversificación de los cultivos alimentarios en los establecimientos rurales, elemento esencial para la Seguridad Alimentaria y Nutricional de los propios agricultores y feriantes. En lo que respecta al mantenimiento y fortalecimiento de este territorio de comercialización, se evidencian los efectos de las diferentes acciones y del apoyo brindado por la gestión municipal en el espacio analizado. Se concluye que las acciones públicas efectivas y las interrelaciones entre productores y consumidores fortalecen el avance y la consolidación de prácticas agroecológicas, el protagonismo y la reproducción socioeconómica de los agricultores familiares, además del arraigo cultural de este territorio de comercialización. 2025-12-05T00:00:00Z https://ri.ufs.br/jspui/handle/riufs/25391 Título: Movimentos sociais e a produção do espaço urbano em Aracaju Autor(es): Almeida, Ana Flávia Alves de Oliveira Abstract: The capitalist development model has brought about transformations in the economic, social, political, historical, and environmental spheres, which manifest themselves in the lived space of humanity. One of the most evident expressions of this process is rapid urbanization, which does not occur without tensions. This thesis contributes to elucidating the contradictions of urban expansion by specifically addressing the municipality of Aracaju, based on the conception of social movements as an expression of class struggle in relation to the State. Its central objective is to analyze the role of urban social movements in confronting the commodification of space, as well as in ensuring access to housing and the social production of space in Aracaju, in light of real estate expansion in the 21st century. Social movements are not exclusive phenomena of the contemporary world; their origins date back to the early formation of the State, a period marked by conflicts between social classes and disputes for political power, which laid the foundation for the emergence and development of contemporary social movements. The analysis is grounded in the historical-dialectical method, which allows for understanding, based on the category of totality, that social conflicts develop in permanent tension, expressing their contradictions. In the urban space, this framework is manifested through the division of space among social classes and the transformation of housing into a commodity, subordinated to the logic of financialization, particularly within the real estate market. In this sense, urban social movements face the challenge of avoiding co-optation by the legitimizing architecture of the dominant class’s ideological framework. The research compared three movements operating in different regions of Aracaju, making it possible to understand that the State does not act homogeneously. Its intervention varies according to location, the potential for land value appreciation, and political interests. In central areas, the State’s response tends to be more conflictual and legally repressive; in peripheral areas, mediation may take the form of negotiation or partial incorporation of demands. In situations involving the formal transfer of land, there is a transformation of social struggle into a governmental program, often subordinated to budgetary constraints and the guidelines of prevailing urban planning.; El modelo de desarrollo capitalista ha provocado transformaciones en los ámbitos económico, social, político, histórico y ambiental, que se manifiestan en el espacio vivido de la humanidad. Una de las expresiones más evidentes de este proceso es la rápida urbanización, que no ocurre sin tensiones. Esta tesis contribuye a dilucidar las contradicciones de la expansión urbana, abordando específicamente el municipio de Aracaju, a partir de la concepción de los movimientos sociales como expresión de la lucha de clases frente al Estado. Su objetivo central es analizar el papel de los movimientos sociales urbanos en el enfrentamiento de la mercantilización de los espacios, así como en la garantía del acceso a la vivienda y de la producción social del espacio en Aracaju, a la luz de la expansión inmobiliaria en el siglo XXI. Los movimientos sociales no son fenómenos exclusivos del mundo contemporáneo; su origen se remonta a los inicios de la formación del Estado, período en el que se identifican conflictos entre clases sociales y disputas por el poder político, que sirvieron de base para el surgimiento y desarrollo de los movimientos sociales contemporáneos. El análisis se fundamenta en el método histórico-dialéctico, que permite comprender, a partir de la categoría de totalidad, que los conflictos sociales se desarrollan en tensión permanente, expresando sus contradicciones. En el espacio urbano, este escenario se manifiesta a través de la división del espacio entre clases sociales y de la transformación de la vivienda en una mercancía, subordinada a la lógica de la financiarización, especialmente en el mercado inmobiliario. En este sentido, los movimientos sociales urbanos enfrentan el desafío de evitar la cooptación por parte de la arquitectura de legitimación del carácter ideológico de la clase dominante. La investigación comparó tres movimientos que actúan en distintas regiones de Aracaju, lo que permitió comprender que el Estado no actúa de manera homogénea. Su intervención varía según la localización, el potencial de valorización del suelo y los intereses políticos. En áreas centrales, la respuesta estatal tiende a ser más conflictiva y jurídicamente represiva; en áreas periféricas, la mediación puede asumir formas de negociación o de incorporación parcial de las demandas. En situaciones de cesión formal de terrenos, se observa la transformación de la lucha social en un programa gubernamental, frecuentemente subordinado a las limitaciones presupuestarias y a las directrices del planeamiento urbano vigente. 2026-03-13T00:00:00Z https://ri.ufs.br/jspui/handle/riufs/25332 Título: Apropriação do relevo e vulnerabilidade socioambiental: análise integrada das unidades de paisagem no município de Arapiraca - AL Autor(es): Gomes, Adsson André da Silva Abstract: The appropriation and occupation of landforms in urban spaces are key factors in the intensification of geomorphological processes and in the generation of socio-environmental vulnerabilities, especially in cities experiencing rapid growth and insufficient territorial planning. The central objective of this thesis is to analyze the impact of land use on the establishment of areas of environmental vulnerability within the landscape units of the municipality of Arapiraca, Alagoas, located in the Agreste region of Alagoas, the second-largest urban center in the state of Alagoas. The study is grounded in a systemic approach, based on General Systems Theory, the geosystem concept, and ecodynamics, integrating physical-natural and socioeconomic variables to understand landscape units and their levels of environmental vulnerability and stability. The methodology involved the application of geoprocessing techniques and Geographic Information Systems (GIS), including the production of thematic maps of geology, geomorphology, soils, land use and land cover, climate, and hydrography. Environmental vulnerability was assessed using the methodology proposed by Crepani et al. (1996, 2001, 2008). The socio-environmental analysis was complemented by the construction of a sustainability index based on demographic, economic, and infrastructure indicators derived from IBGE census data for the years 1991, 2000, 2010, and 2022, allowing for an evaluation of the temporal evolution of sustainability conditions in the municipality. The results indicate that urban expansion in Arapiraca has occurred in a fragmented and uneven manner, largely disregarding geoenvironmental constraints. This process has intensified erosion, mass movement, flooding, and the degradation of water resources, particularly in landscape units associated with dissected relief surfaces and aggradational plains. These areas exhibit the highest levels of environmental vulnerability, especially in zones of urban expansion and informal occupation. Conversely, areas with better infrastructure and more structured urban planning show higher levels of socio-environmental stability. The study concludes that landform appropriation driven primarily by economic and real estate interests, without adequate consideration of environmental limitations, increases geomorphological instability and amplifies socio-environmental risks. The proposed ecological-economic zoning emerges as a strategic tool to support territorial planning and environmental management, contributing to vulnerability reduction and the promotion of more sustainable urban development in Arapiraca. 2026-02-27T00:00:00Z
