In this context, the present study aimed to map and characterize the land use and cover of the Fazenda Escola at the State University of Maranhão (UEMA), São Bento Campus, located in the Baixada Maranhense Environmental Protection Area. The research is characterized as descriptive, with a qualitative approach and exploratory nature, based on a bibliographic survey, field data collection, and the application of geoprocessing tools. The information was obtained with the aid of a GPS receiver and the OsmAnd application, and subsequently processed in QGIS software for the preparation of thematic maps. The classification of the areas was based on Collection 10 of the MapBiomas2024 Project. Seven classes were identified, with a predominance of Forest Formation, followed by Flooded Field and Swampy Area, Other Non-Vegetated Areas, Other Temporary Crops, Oil Palm, Other Perennial Crops, and Urbanized Area. The results demonstrate that the Fazenda Escola reconciles academic activities and agricultural production with native vegetation areas, highlighting the potential of geotechnologies to support conservation.

In the municipality of São Bento, Maranhão, particularly along the MA-310 highway, the occupation of ecologically sensitive areas has caused significant environmental impacts. In this context, this study aimed to assess the environmental impacts resulting from urbanization in the floodplain fields of São Bento (MA) through the application of the Leopold Matrix. The methodology was based on a literature review, field surveys, photographic records, and a systematic analysis of interactions between anthropogenic activities and environmental components. The results indicated a predominance of negative impacts of low to medium magnitude, especially related to improvised landfilling, removal of native vegetation, soil impermeabilization, improper solid waste disposal, discharge of domestic effluents, and open-air burning. These impacts compromised natural hydrological dynamics, biodiversity, environmental quality, and public health, in addition to promoting progressive landscape degradation. It is concluded that the Leopold Matrix proved to be an effective instrument for identifying and ranking environmental impacts, contributing as support for environmental planning and the proposal of mitigation measures aimed at conserving floodplain fields and promoting more sustainable urban development in the studied municipality Wed, 01 Jan 2025 00:00:00 GMT https://repositorio.uema.br/jspui/handle/123456789/5954 2025-01-01T00:00:00Z https://repositorio.uema.br/jspui/handle/123456789/5912 Título: Influência da agricultura familiar nas dinâmicas de uso e cobertura da Terra na área do Rio Santa Bárbara Povoado Olho d'Agua dos Moraes - São Bento MA Abstact: The transformations in land use and land cover in the Maranhão Amazon, especially in the Pericumã River Hydrographic Sub-basin, have caused intense environmental degradation characterized by the reduction of native vegetation, erosive processes, silting, and loss of ecological connectivity. These impacts stem primarily from the expansion of family farming without sustainable management practices in a region marked by high ecological vulnerability and increasing anthropic pressure. Between 1994 and 2024, this study integrated Remote Sensing techniques, Geographic Information Systems (GIS), and multitemporal analysis to delimit the sub-basin, map land use classes, and validate the results through fieldwork at the Santa Bárbara stream. The data reveal a significant conversion of natural areas into pastures, temporary crops, and open surfaces, intensifying degradation processes and weakening water environments. Although family farming is fundamental for local subsistence and socioeconomic dynamics, its practice without conservation techniques increases environmental vulnerability. Conversely, the study demonstrates that sustainable soil management, the adoption of agroecological practices, and conservation strategies can recover degraded areas and strengthen landscape resilience. The results offer relevant insights for territorial planning and the formulation of public policies aimed at reconciling agricultural production, water resource protection, and ecosystem conservation in the Pericumã River Hydrographic Subbasin.
