Item Uso de geotecnologias no diagnóstico da mata ciliar do Reservatório Engenheiro Francisco Sabóia, Ibimirim - PE(2023-04-13) Silva, Jaimeson Jardel França da; Duarte, Simone Mirtes Araújo; Vasconcelos, Géssica dos Santos; http://lattes.cnpq.br/0802316667174979; http://lattes.cnpq.br/5876968040869585; http://lattes.cnpq.br/9465682002571649With the development of cities, disorderly occupations have grown exponentially, impacting many vegetation formations, especially riparian forests, even though they are still protected by law for being in Permanent Preservation Areas (PPAs) and presenting great importance in maintaining the quality and stability of water bodies, such as in artificial water reservoirs, which provide society with regulation and water supply, especially in regions with water scarcity, such as the Caatinga. Therefore, the present study aims to diagnose the situation of riparian forests in the PPA strip around the Engineer Francisco Sabóia Reservoir, located in the municipality of Ibimirim, in the state of Pernambuco, seeking to understand and describe the degrees of degradation and conservation, verifying their adequacy in relation to current environmental laws, in a GIS environment. Through documentary research, the absence of licensing was verified, and consequently, the corresponding PPA strip was not defined. Therefore, for the study, a measurement of 100m was considered according to CONAMA Resolution 302/2002. High-resolution images from the CEBERS 4A satellite were used. The data were manipulated in QGIS software to create thematic maps of land use and occupation, through supervised classification of five classes: water, consolidated vegetation, shrub vegetation, agriculture, exposed soil, the NDVI map to quantify the percentage of preserved and degraded riparian forest, and the slope map to understand the altimetric configuration of the region. As results, the land use and occupation map showed the presence of agricultural activity with approximately 22%, as well as approximately 9% of exposed soil, 9% of consolidated vegetation, 25% of shrub vegetation and water 35%, evidencing non-compliance with the legislation. In addition, the NDVI calculation clearly indicated the fragility of vegetation throughout the extension of the PPA, with few fragments of vegetation cover and a lot of area with dead or water-stressed vegetation. It is concluded that this diagnosis has results capable of guiding effective management with planning based on territorial planning and restoration actions of the reservoir's PPAs, providing reflections on the environmental situation of an area with such environmental, economic, and social importance for a severely degraded biome.Item Dinâmica de uso e ocupação do solo em áreas de preservação permanente do Reservatório do Pirapama, Cabo de Santo Agostinho – PE(2019-07-11) Moraes, Maria Clara Gomes de; Silva, Emanuel Araújo; http://lattes.cnpq.br/2765651276275384; http://lattes.cnpq.br/7061662162165388Action on natural environments occurs in parallel with human evolution on the planet, so the absence of adequate planning associated with the disorderly growth of cities and agricultural activities directly influence the decharacterization and dysfunctionality of PPPs. In view of the above, the objective of this work was to raise the occurrence of conflicts of land use and occupation in the Permanent Preservation Areas of the Pirapama-PE Reservoir between 2003 and 2018, according to the protection parameters established by environmental legislation. To do so, the APPs were delimited using the software Google Earth Pro and through the software QGis 2.14 was generated the shapefile for trimming the study area. Therefore, using images from the Landsat 5 and 8 satellites, TM (Thematic Mapper) and OLI / TIRS (Operational Land Imager / Thermal Infrared Sensor) with resolution of 30 meters, from 2003, 2010 and 2018, it was possible to map 5 classes of use and occupation of the soil in the 1: 35,000 scale in the QGis environment. The supervised classification of the images was done through the SCP plugin, and the accuracy of this mapping was evaluated by the Kappa Index. The evolution of the conflicts of use of the soil was obtained by means of the overlap of the maps generated with the classifications of the images. In possession, it was possible to determine the amount of preserved APPs and of area in disagreement with the legislation. The results showed that anthropic activities impacted almost 4.65 km² of native vegetation, equivalent to 33.3% of the study area. There was a significant reduction in the "forest preserved" class of land use for agriculture, urban area and exposed soil, from 90.4% in 2003 to 81.8% in 2010 and decreased to 66.7% by 2018 (17.6%) of the area, being the main occurrence of land use conflict of PPAs. By the Kappa index, the image ratings of the years 2003 and 2010 obtained the "very good" result, being 0.62 and 0.80, respectively, while the classification of the year 2018 obtained an "excellent" result, corresponding to 0 , 82 by index. Considering the decrease of the time for territorial monitoring, the importance of the study of the dynamics of land use and occupation through remote sensing for the management and inspection units is highlighted. Such studies are essential for making decisions regarding the management and maintenance of these areas in front of legislation and environmental preservation.
