The research is based on the growing degradation of soil in urban areas, aggravated by disorderly growth and the replacement of natural vegetation with impermeable surfaces, which intensifies surface runoff and, consequently, the impacts of erosion. The research was based on a theoretical-methodological approach that combines concepts from Geography, Geomorphology and Soil Science, as well as highlighting the role of experimental stations as an environmental monitoring tool. In the practical field, two experimental stations were set up with different vegetation covers (grass and tree vegetation), in which data was collected on rainfall, surface runoff and sediment loss. The results showed that areas with vegetation cover had lower rates of soil loss and runoff, confirming the effectiveness of vegetation in mitigating erosion processes. The research reinforces the importance of continuous monitoring and the implementation of public policies aimed at soil conservation and sustainable urban planning Mon, 23 Jun 2025 00:00:00 GMT https://repositorio.uema.br/jspui/handle/123456789/5683 2025-06-23T00:00:00Z https://repositorio.uema.br/jspui/handle/123456789/5646 Título: Educação antirracista e saberes ancestrais afro-indígenas no ensino de geografia - intervenção pedagógica em Central do Maranhão/MA Abstact: This course conclusion monograph addresses geographic education with an anti-racist character, based on the pedagogical intervention carried out in a public school in Central do Maranhão associated with other investigative practices as well as local Afro-indigenous knowledge related to the use of plants. I have as protection to Law 11.645/08 (which extends to Law 10.639/03), which becomes obligatory or ensino of Afro-Brazilian and indigenous History and Culture, and as Diretrizes Curriculares Nacionais para a Educação das Relações Etnico-raciais e para o Ensino of History and Culture Afro-Brasileira e Africana (CNE, no. 1/2004). The general objective of the study presented here is to promote the article of two school contents such as local knowledge regarding the use of medicinal plants in the reality lived by two students from Central do Maranhão, to promote spatial thinking and an anti-racist stance. Therefore, there are only specific objectives: (i) promote the valorization of the knowledge that circulates in the family nucleus through orality and that is also the economic base that sustains the workers; (ii) highlight the geographical relationships present from the spatial dimension to the two farms and trade in the fairs, to the Afro-indigenous ancestral origin of the knowledge that circulates based on preconceptions and, at the same time, to the sustainable and more harmonious relationship with the environment based on a cosmoperception . Using the phenomenological method in education, this qualitative research involves the methodological procedures: bibliographic survey relevant to ethnic-racial themes (legislation, Afro-indigenous knowledge, education and geography teaching); field research in Central do Maranhão/MA and religious practices not povoado quilombolas as sources of phenomenological investigation of local Afro-indigenous knowledge; Pedagogical intervention with the use of active methodologies in a didactic sequence of four classrooms for the 8th and 9th grade at the Valdecy Viana Prazeres municipal public school. In the intervention, a didactic sequence of 4 classrooms was carried out with the use of varied pedagogical practices (questionnaires for prior diagnosis, inverted classroom, research with family members at home and presentation of two research results for students, exhibition and debates of videos and preparation in a group of mental maps like consolidation of learning). Orality, corporeality and circularity are ancestral Afro- indigenous values and can be reestablished with varied pedagogical practices allied to the investigation of local knowledge that constitutes the origins and daily life of many students of Central do Maranhão, especially the quilombolas. Thus, rescuing the primary sources of research now and again, associating with recording, recording and photographing these subjects-narratives provides an existential repositioning of quilombolas people, as subjects of knowledge in the historical plot that we very well know and produce with their territories and lived places. Finally, this research is considered as a community legacy – one that originates long before the intervention, has been dreamed of not between two ancestors, and that extends beyond two school walls, allied to anti-racist struggle and geographic education of a critical nature. , creative and emancipatory is a practice articulated between scientific knowledge, School content and specific knowledge of communities in the valorization of ethnic-racial identities lived by students and residents of Central do Maranhão. That the teaching of geography can convey an anti-racist geographic education inspiring emotional, political and theoretical-practical relationships that guarantee a transformative education Wed, 08 Jan 2025 00:00:00 GMT https://repositorio.uema.br/jspui/handle/123456789/5646 2025-01-08T00:00:00Z https://repositorio.uema.br/jspui/handle/123456789/5645 Título: Ocupação e degradação em manguezal no bairro Portelinha, São Luís - MA. Abstact: In recent decades, the mangrove has been one of the most degraded ecosystems due to the consequences of pollution, extractivism and deforestation. The current work addresses degradation as a consequence of occupation for housing purposes in the Portelinha neighborhood, causing a series of irreversible damages, mainly to biodiversity. The aforementioned neighborhood is located between São Francisco and Ponta D’areia. The ten-year multi-temporal analysis stands out, based on the years 2014 and 2024, aiming to analyze the dynamics of occupation and degradation of mangroves in the area. In this way, highlighting its essential and exclusive role in the development of the biodiversity that has it as a natural habitat. Bibliographical research, field visits and later analysis were carried out using satellite images to understand the advance of occupation over the mangrove in the last decade. Finally, the impacts on the physical/biological environment and also on the anthropic environment are exposed Fri, 16 Aug 2024 00:00:00 GMT https://repositorio.uema.br/jspui/handle/123456789/5645 2024-08-16T00:00:00Z https://repositorio.uema.br/jspui/handle/123456789/5644 Título: Gestão dos recursos hídricos na cidade de São Luís - Maranhão Abstact: Water is an essential resource for life, and its efficient management is fundamental to the social and environmental well-being of urban populations. This study focuses on the city of São Luís, capital of the state of Maranhão, which faces serious structural challenges regarding water resource management. The central objective of the research was to analyze how water governance occurs in the city, with emphasis on the role of the Environmental Sanitation Company of Maranhão (CAEMA), the application of the National Water Resources Policy, and the planning and monitoring instruments used. The methodology followed a quantitative approach, including bibliographic and cartographic surveys, technical visits—such as the one conducted at CAEMA headquarters—and data analysis from institutions such as IBGE, SNIS, and the Water and Sanitation Institute. The data show that the Italuís System is responsible for approximately 60% of the city's water supply, supplemented by systems such as Sacavém, Paciência, Cidade Operária, and over 280 deep tubular wells. The city also features several Sewage Treatment Plants (ETEs), such as the Anil ETE, inaugurated in 2023, which directly benefits about 50,000 residents across 12 neighborhoods. On the other hand, persistent issues were also identified: 55.93% of the water is lost before reaching consumers, only 49.85% of the population has access to sewage collection services, and 13,980 residents lack piped water, relying on manual alternatives. Additionally, the metering index is below the national average, which compromises consumption control and efficiency. It is concluded that although the city has infrastructure and policies aligned with national guidelines, operational and social weaknesses persist, limiting full access to quality water. Institutional strengthening, reduction of water losses, and active public participation are essential for building a more equitable, efficient, and sustainable management of water resources, ensuring water as a public and fundamental right Tue, 01 Jul 2025 00:00:00 GMT https://repositorio.uema.br/jspui/handle/123456789/5644 2025-07-01T00:00:00Z
