However, anthropogenic activities tend to intensify this process, increasing soil loss and associated environmental impacts. Land appropriation and occupation contribute to the destabilization of natural processes by disrupting the dynamic equilibrium and altering hydrological processes, especially water infiltration into the soil. In this context, the watershed has been widely adopted as a unit of analysis, as it enables the integration of physical and socioeconomic aspects. The main objective of this research is to understand soil loss resulting from water erosion, as well as to analyze land appropriation and occupation patterns within the Ribeirão São Lourenço watershed, located in the municipality of Ituiutaba, Minas Gerais, Brazil, and the environmental responses to these interventions. To achieve this objective, the following methodological procedures were adopted: (a) literature review of key concepts; (b) collection of data and cartographic bases; (c) extraction of morphometric parameters; (d) fieldwork for sample collection and photographic records; (e) morphological and granulometric soil analysis; (f) preparation of thematic maps, including location, fluvial hierarchy, hypsometry, slope, geology, geomorphology, soils, land use and land cover, and erosive features; and (g) determination and spatialization of the factors of the Universal Soil Loss Equation (USLE), namely: R factor (rainfall erosivity), K factor (soil erodibility), LS factor (topographic factor), and CP factor (cover, management, and conservation practices). The results indicate that the Ribeirão São Lourenço watershed has a drainage area of 294.11 km² and a perimeter of 119.02 km. The study area shows a low propensity for major flooding due to its elongated shape. In addition, the gently undulating relief, with low altimetric amplitude, combined with low hydrographic and drainage densities, indicates lower susceptibility to intense erosive processes. Regarding the USLE factors, the R factor presents an average value of 7720.49 MJ·mm·ha⁻¹·h⁻¹·year⁻¹, with an average annual precipitation of 1363.6 mm. The K factor ranges from 0.0479 to 0.0792 t·ha·h·ha⁻¹·MJ⁻¹·mm⁻¹, associated with Oxisols, Gleysols, Entisols, and Inceptisols developed over the Marília, Vale do Rio do Peixe, and Serra Geral formations. The predominant LS factor ranges from 0 to 2, covering approximately 82.3% of the area, reflecting low slopes. The CP factor ranges from 0, in areas with adequate soil cover and management, to 1, in areas of exposed soil. Regarding annual soil loss, 72.9% of the watershed presents losses of up to 10 t·ha⁻¹·year⁻¹, indicating a predominance of low-intensity sheet erosion. However, 268 occurrences of linear erosive features were identified, mainly concentrated in the upper and lower courses of the watershed, as well as in headwater areas. The integrated analysis of the sampling points showed that land appropriation and occupation have intensified erosive dynamics and, consequently, soil loss, reflecting the current morphodynamics of the watershed. In this context, the research contributes not only to the advancement of academic knowledge but also provides relevant support for territorial management and urban and environmental planning, aiming at soil and water conservation through an integrated socio-environmental approach. 2026-04-24T00:00:00Z https://repositorio.ufu.br/handle/123456789/50184 Title: Produção do espaço urbano em cidades de porte médio: um estudo da morfologia urbana em Ituiutaba (MG) e Jataí (GO) Abstract: This dissertation aimed to understand the characteristics of the intra-urban space of the cities of Ituiutaba (Minas Gerais) and Jataí (Goiás), both located in Brazil, through a study of urban morphology, contributing to broader discussions on medium-sized cities and to urban planning. The research was based on data from the 2022 Demographic Census, provided by the IBGE, especially the Cadastro Nacional de Endereços para Fins Estatísticas (CNEFE) database, combined with the use of space syntax and cartographic representations, such as the Kernel density estimator, enabling a more in-depth reading of the spatial organization of these cities, in addition to fieldwork conducted to identify the areas and verify the information. The justification for the study lies in the need to expand the understanding of medium-sized cities, which, in light of the increasing complexity of the urbanization process, present ever more significant challenges for urban management. The theoretical framework was grounded in the analysis of contemporary urbanization under a capitalist logic, highlighting the role of different agents in the production of urban space and in shaping urban morphology. As a result, a morphological study was developed through graphic modeling of both cities, demonstrating the potential of this approach as a tool to support urban management. Furthermore, a comparative study of the two cities was carried out, making it possible to understand the specificities that reflect their distinct historical and economic processes, highlighting the complexity of urban space production in medium-sized cities. Thus, the research reinforces the importance of advancing studies on medium-sized cities, especially through the use of public databases, spatial representations, and methodological approaches that consider urban morphology and contribute to comparative analyses. 2026-05-29T00:00:00Z https://repositorio.ufu.br/handle/123456789/49835 Title: A presença de Aedes aegypti em pontos estratégicos na cidade de Uberlândia (MG) Abstract: ABSTRACT INTRODUCTION: Strategic Points (SPs) are non-residential household properties whose activities have the potential to create and spread the Aedes aegypti mosquito. Among the SPs of greatest entomological concern are tire shops, junkyards, cemeteries, airports, and recycling depots. OBJECTIVE: To evaluate the presence of Aedes aegypti in SPs and its correlation with cases of dengue reported in Uberlândia, Minas Gerais (MG), Brazil. METHODS: A non systematic bibliographic and documentary review, mathematical calculations and analyses, basic correlation statistics (Pearson), and simple linear regression of the Building Infestation Indices (BIIs) of the SPs compared with reported cases of the disease. Secondary data were also used, collected in partnership with the Aedes control program of the Health Surveillance Unit (UVS) and the Epidemiological Surveillance Department (VIGEP) for the year 2021. RESULTS: By the end of 2021, there were 495 registered SPs in Uberlândia (MG). A total of 10,559 household visits were carried out across 26 entomological cycles, with an average of 406 SPs visited per cycle and 2,311 visits not completed, showing a variation in the Pendency Index (PI) from 4.65% (23) to 59.19% (293) per cycle. The annual average of building infestation was 30.15%, and per cycle it ranged from 0.2% (1) to 22% (90) of properties with mosquito presence relative to the number of visits per cycle. Based on the thresholds for dengue transmission risk, four cycles showed a satisfactory BII below 1%; eight cycles were in the alert range (1% to 3.9%); and 14 were classified as high risk (above 3.9%). The observed correlation between the BIIs of SPs and the reported dengue cases during the period was 0.73. CONCLUSION: A positive and relatively strong correlation between the variables was observed, indicating that for each unit increase in the BII of SPs, an increase of 2.51 in reported dengue cases is expected in the city. The study highlights the existence of monitoring without effective control of the mosquito's presence in registered areas, showing that SPs are not only locations that facilitate the introduction and proliferation of the vector but are also key areas where indicator results tend to significantly influence the rise in disease notifications in Uberlândia (MG). Therefore, the dissemination and qualification of indicator results associated with SPs are essential to promote the right to individual and collective public health, particularly regarding public policies for Aedes aegypti control and disease prevention.

From the perspective of Critical Geography, the study is grounded in the analytical categories of form, function, structure, and process, as outlined by Milton Santos, and adopts the Right to the City, as formulated by Henri Lefebvre (2001) and David Harvey (2004), as the central axis for interpreting urban reality. The CAIC is understood as a multifunctional public facility whose role transcends the limits of formal education by integrating social, cultural, welfare, and health policies, thereby assuming a strategic function in territorial organization and in the promotion of peripheral urban centralities. The methodology is based on a qualitative approach, combining different research techniques: participant observation, document analysis, bibliographic review, and the application of semi-structured questionnaires to neighborhood residents, school professionals, and social actors who experienced the implementation and development of the CAIC’s subprograms. Data analysis made it possible to grasp representations, everyday practices, and lived experiences, revealing how the presence of the school and the provision of public services materialized in networks of sociability, forms of spatial appropriation, and new meanings attributed to the territory. The results indicate that the subprograms linked to PRONAICA, focused on early childhood and elementary education, culture, school meals, sports, health, and preparation for work, played a significant role in shaping both the physical and social configuration of the Novo Tempo II neighborhood. These actions contributed to expanding access to basic rights and strengthening community bonds. In this context, the school has consolidated itself as an institutional reference point in a territory historically marked by deficiencies in urban infrastructure, promoting both material and symbolic transformations in the daily lives of residents. However, the research also highlights the limits of institutional action, particularly regarding the discontinuity of public policies, the lack of intersectoral coordination, and the fragility of communication strategies with the local community. These weaknesses undermine the effectiveness of the programs and place the sustainability of the social gains achieved at risk. The analysis of socio-spatial dynamics allows us to affirm that the CAIC has become a structuring agent of the territory, but that its impact depends directly on the continuity of integrated public policies, recognition of local specificities, and the active participation of the population in the management of common goods. It is concluded that the experience of the CAIC in the Novo Tempo II neighborhood represents an important analytical key for understanding the effects of public facilities on the production of urban space in medium-sized Brazilian cities. The research contributes to the debate on spatial justice, socio-educational inclusion, and territorial transformation, demonstrating that the right to the city can only be fully realized when public policies are conceived in an integrated, democratic, and context-sensitive manner, attentive to the realities of those who inhabit marginalized urban spaces. 2025-07-10T00:00:00Z
