(2018) Silva, Jéssica Bruna Alves da; Duarte, Simone Mirtes Araújo; http://lattes.cnpq.br/5876968040869585; http://lattes.cnpq.br/2314483831159897
Geotechmoçogies and remote sensing help in the evaluation and monitoring of natural resources, in an effective and economical way, allowing the identification of the possible causes and consequences of the environment in the area interest. In this way, the present work aimed to evaluate the dynamicsof land use and occupation and its impacts in the city of Alagoinha - PE using geotechnology. All the geoprocessing was carried out in the free software SPRING 5.5.3, in which the numerical model of the terrain was performed using SRTM data, which enabled the characterization of the relief through the hypsometric and slope analysis.Trough the satelite images Landsat 7 ETM + and Landsat 8 OLI of the years 2002 and 2017, the Adjusted Multispectral Composition, the calculation of Normalized Difference Vegetation Index - NDVI, the classification of the use and occupation of the soil of the municipality and its anthropism, as well as the social imapcts of such use and occupation. It was observed that the largest area of the municipality (27,71%) is at altitude between 710-760m and the slope varies between 0 - 5° in 61.78% of the area, characterizing the relief with bein flat / smooth wavy. Regarding the results of the digital image processing, it was identified that all the established classes presented variations, and the classes that more attracted attention were the class of Dense Vegetation, that presented an increase of 16,04 km² (7.74%) of the area, and the Soil Exposed classe, which presented a decrease of 8.06 km² (3.87%). In the analysis of the social impacts, it was possible to establish a relationship with the assistance programs, in the Federal, State and Municipal spheres, with the increase of the vegetal cover, water mirrors and the reduction of the soil exposure, also noting that it was not environmental education and recognition of the importance of natural resources in the quality of life of the population.

(2020-11-03) Moura, Lucas Araujo; Duarte, Simone Mirtes Araújo; Moreira, Giselle Lemos; http://lattes.cnpq.br/6171199372079024; http://lattes.cnpq.br/5876968040869585; http://lattes.cnpq.br/2567696308015910
The geotechnologies linked to remote sensing are essential tools to understand the use and occupation of a territory, in addition to effectively and economically assisting in the monitoring of natural resources. Through data from different years, it is possible to create a study of the main factors of degradation of natural resources. Thus, the present work aimed at elaborating a temporal analysis of the municipality of Macaparana - PE for the years 2007 and 2018. All the geoprocessing activities for the supervised classification and vegetation index generation were computed through the software Qgis version 2.18.10 and 3.10.9, the supervised classification was performed through the Semi Automatic Classification Plugin (SCP), where several samples were selected in the bands compiling for the due years, and through the MaxVer, the classes of exposed soil/urban area, agricultural culture, forests and water resources were computed. For the accuracy of the data, the kappa index was performed. The kappa index for the years 2007 and 2018 was 0.49 and 0.79, showing that it is a good mapping. And through the maps generated and the quantified classes, where the exposed soil of the area increased by 48%, the vegetation had a decrease of 35%, the agricultural crop had its area reduced by 10% and the water resources increased about 303%. There was a big change in the results of water resources due to the amount of clouds in the image of 2018, which hindered the classification, but when going to the field it was possible to observe, lack of vegetation in the area around the water resources, which may occur a process of silting up the rivers. It was possible to establish a relationship between the exposed soil and the agricultural crop, the lack of effective management in search of greater productivity instead of cutting more areas to plant, justified with the data of the vegetation area, which decreased to give space to new agricultural crops. And relating the forest area obtained through the supervised classification, with the area computed from IVDN, showed homogeneity in the results, varying less than 5% for the two years. Therefore, it is possible to conclude that anthropic activities, without any management plan for planting and harvesting, are having direct effects on the reduction of vegetation in the area, requiring better control in their production and alternatives that do not require burning cane for cutting, where it has direct impacts on the soil.

(2018) Castro, José Artur Borges de; Duarte, Simone Mirtes Araújo; http://lattes.cnpq.br/5876968040869585
The hydrographic region of the Middle Jaguaribe is an area of vital importance to the state of Ceará, benefiting the whole region around it with fish farming, irrigation, water transposition and, as a consequence of the dam, regulates the flow of the Jaguaribe River. Its construction began in 1995 and concluded in 2003. In recent years, there has been a reduction in precipitation, which means that reservoirs are not recharged, reducing local economic dynamics. Following this reasoning, the objective of this work is to make a temporal analysis of the use and occupation of the soil of the Jaguaribe mid basin during a period of nine years, between 2006 and 2015, using LANDSAT 5 ETM satellite images in the year 2006 and LANDSAT 8 OLI for 2015, provided by the United States Geological Survey (USGS), the images used in the process were recorded during the dry period of the region, and using GIS applications it is possible to quantify the exposed soil, vegetation, agricultural activities and urban areas , and estimating morphometric variables. The results show a visible reduction of vegetation and soil growth, caused by the reduction of the levels of the small reservoirs and by anthropic activities, and the morphometric results indicate that the basin is not conducive to flooding.

(2018) Oliveira, Laura Maiara de Freitas; Duarte, Simone Mirtes Araújo; http://lattes.cnpq.br/5876968040869585; http://lattes.cnpq.br/4957483273304674
Since the beginning of human existence, this has been interfering with the stability and healthy development of nature. The vital need of fresh water for humanity, propels it to allocate itself in areas near the mirrors of water. However, today we understand that the constant presence of human actions and the removal of existing vegetation in these places, causes impacts to the sources and courses of water, which can result in the loss of these, to the environment. Considering the preservation and conservation of these environments, it is extremely important to investigate the areas considered as permanent preservation, which are protected according to the Brazilian Forest Code. The São Pedro River is the object of study of this work, it is located in rural area of the state of Paraíba. The objective is to investigate whether or not the legislation on Ciliary Forest, in this sub-basin, is considered as requiring 30 m of vegetation bordering its edges and radius of 50 m of vegetation in its springs. Geotechnology tools such as satellite images, SRTM images, Shapefiles and Spring software were used for these results, which allowed the observation and classification of these areas. The characterization of the occupation of the terrestrial surface and the antropism in the place were used. It was concluded that in the APPs of springs 50% and 28.33% are of sparse vegetation and soil exposed respectively, as well as, about 34.73% of sparse vegetation and 19.97% of soil exposed in the margins APPs. In the springs, 100% of the APPs have human interference, and approximately 85.92% in the river banks, which can generate serious future problems for the environment and even humans. Thus, it is observed the need for field studies in the most modified areas, as well as actions aimed at sensitizing the population on the importance of permanent preservation areas in rural areas.

(2018) Silva, Júlia Andresa Freitas da; Duarte, Simone Mirtes Araújo; http://lattes.cnpq.br/5876968040869585; http://lattes.cnpq.br/5132661779293685
The study of the characteristics of a river basin allows one to understand its dynamics and to carry out an adequate management of its resources. With this in view, the present work aimed to characterize morphometrically the sub-basin of the Gurjaú River, in the Metropolitan Region of Recife -PE, through geotechnologies. In this study, a shapefile of the municipalities of Pernambuco was used, which assisted as a visual reference to locate the water course, and an SRTM image of spatial resolution of 30 mx 30 m, referring to the study area, provided by the National Institute of Space Research (INPE). Using Google Earth Pro, the Gurjaú River was identified. The image was imported into the free software Spring 5.5.4 ̧ where the isolines, the water flow directionmatrix and the flow matrix accumulated in each cell were generated, which were used to delimit the sub-basin. The area and perimeter of the basin were measured and the water flowswere vectored. The altitude was rated 30 by 30 meters. The gradient grid was generated, and the maps of hypsometry and slope were elaborated. The following morphometric parameters were calculated: compaction coefficient (Kc), circularity index (Ic), shape factor (Kf), elongation ratio (Re), drainage network, drainage hierarchy, drainage density (Dd) (Dh), torrentiality coefficient (Ct), maintenance coefficient (Cm), roughness index (HD) and relief ratio (Rr). The minimum altitude found in the sub-basin was 0 m, and the maximum altitude was 370 m. The most representative altitude class along the sub-basin was between 90 and 120 m, while the least representative was between 360 and 390 m. The minimum slope was 0% and the maximum found was 181.57%. The relief of the region is mostly wavy, presenting between 8% and 20% of slope. The area found was 148,115 km², the perimeter was 68,948 km and the axial length of the sub-basin was 22,723 km. The values obtained for the morphometric characteristics were: Kc = 1.586; Ic =, 392; Kf = 0.287; RL = 0.604; total length of watercourses = 110,226 km; hierarchy of channels = 4th order; Dd = 0.744 km.-2; Dh = 0.317; Ct = 0.235; Cm = 1344.09 m².m-1; HD = 0.277; Rf = 16.28. It was possible to notice that the sub-basin of the Gurjaú River has an elongated form, with slopes not very steep, and therefore is not subject to floods.

(2018) Silva, Satyro Barbosa da; Duarte, Simone Mirtes Araújo; Silva, Hernande Pereira da; http://lattes.cnpq.br/1800835100486343; http://lattes.cnpq.br/5876968040869585; http://lattes.cnpq.br/6865576903260120
The benefits that urban tree-planting provides to communities where there are established trees, such as providing shade for pedestrians, physical soil stabilization, reducing the impact of rain, avoiding heat islands and biological deserts, provide scenic beauty and psychological well-being are indisputable, barring or channeling the wind and dampening the sound. However, there are many difficulties encountered in establishing an afforestation project in consolidated urban communities, mainly due to lack of planning, adequate urban furniture, telephony, sanitation and electrical equipment. Trees are sometimes considered as negative points of conflict, being blamed for destroying sidewalks, disrupting electrical wiring, breaking pipes and causing accidents by falling branches or falling over. Based on the principle that the more trees, the better the thermal sensation and the less the need to use treated water in the search for this balance, this work proposes an afforestation project around the five reservoirs administered by Companhia Pernambucana de Saneamento – COMPESA, as a way to benefit communities, not only with sanitation, but also with afforestation. For that, aerial-photogrammetric images of 0.50 x 0.50 m resolution were used, the census of the trees was carried out in the surroundings of the five reservoirs used in the study of the city of Paulista, from which several indices were obtained that allowed to evaluate and elaborate an afforestation plan in the roads that offered the physical conditions to do so. A total of 1,222 individuals were collected, distributed in 19 botanical families and 43 species, in which 86.7% of the species are exotic to the Brazilian flora and 13.3% are native. The most frequent species around the reservoirs were: Ficus benjamina L. (29.7%), Roystonea oleracea (Jacq.) O.F. Cook. (11.3%) and Terminalia catappa L. (10.8%). Based on current standards and similar literature, localities, quantity, adequate distance and species to be planted on the public, road were proposed in order to bring back the well-being that the population needs, totaling 415 trees distributed in 15 species of native origin. The study also shows the need for public intervention through campaigns to raise awareness of the importance of trees and especially in the structuring of roads that lack proper attention.

Urban forestry provides a number of benefits for the environment and society, however, strategic planning is necessary so that the needs are met and the species are best adapted to the desired location. This study aims to use the techniques of geoprocessing applied to urban forestry, in order to perform a survey and evaluation of the individuals present in the main access roads to the city of Ibimirim - PE, in order to provide a database for the construction of a specific Urban Forestry Manual for the municipality. The data collection was carried out in April 2022, under the route of its main roads in the city, all individuals that were on the margins, in central beds or public squares located along this route were inventoried, through a Census inventory and with the use of a field form. Trees, shrubs, cacti and bushes were georeferenced using SurveyCam software available for smartphones, providing decimal longitude and latitude coordinates in order to create thematic maps with the arrangement of individuals through GIS. Through this collection, 412 individuals were inventoried, represented by 14 species, 14 genera and 09 botanical families, where 97% are trees, of these trees 81% are in the adult stage and 16% with drastic pruning, the care of the individuals observed in loco, were performed by the local population.

(2018) Falcão, Cassiano José Lages Marinho; Duarte, Simone Mirtes Araújo; http://lattes.cnpq.br/5876968040869585; http://lattes.cnpq.br/5445952042358738
This paper aimed to estimate laminar erosion susceptibility in Machados County – PE, achieved using the adapted Universal Soil Loss Equation (USLE) and SIG for computing and analyzing data. The methodology used can be split in five steps: collection and integration of rainfall data on a thirty-year interval, local topography analysis using geoprocessing tools, laboratory analysis and posterior geolocation of local soils physical parameters and the final computation through the adapted USLE formulae. The achieved results allowed surmising that the County’s soil loss susceptibility is low, but significant, with a mean value reaching 368t/ha.year. The biggest influential factor was the topographic factor, averaging (…). Soil erodibility was considerably high, with a mean value of (…) and rain Erosivity, found to be (…) had the lowest impact on soil erosion. It is also possible to perceive a considerable spatial variation from the results, despite the reduced area of study, endorsing geotecnology use on its determination.

(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/9465682002571649
With 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.

The analysis of morphometric characteristics such as area, perimeter, slope, altitude, drainage density, among others, are fundamental in the development of environmental studies. The physical and biotic characteristics of a given location play an important role in decisionmaking. In this sense, the development and improvement of techniques together with geotechnologies for morphometric characterization have been the subject of study in several parts of the world, and promote relevant results. In view of the above, the present study aimed to perform the morphometric characterization of the municipality of São João do Sabugi - RN, using data from the ALOS PALSAR Satellite, integrated and processed in a GIS environment. The spatial data obtained were subjected to pre-processing techniques, such as reprojection of its coordinate reference system to UTM (24s time zone) and of its geodetic system to SIRGAS 2000, as well as exclusion of its spurious pixels. These procedures allowed the obtaining of accurate morphometric parameters. The results showed that morphometric characterization, through the processing of Digital Elevation Model (DEM) data in a Geographic Information System (GIS) environment, offers significant advantages in terms of cost-benefit. The methodology applied proved to be adequate and easy to use. The slope of the municipality is predominantly undulating to strongly undulating. The conception of the results achieved in this study allows a consistent understanding of the morphometric behavior of the municipality of São João do Sabugi - RN, which can be used for adequate environmental planning.

(2023-04-26) Ferreira, Loghan Moreira Vasconcelos; Duarte, Simone Mirtes Araújo; http://lattes.cnpq.br/5876968040869585; http://lattes.cnpq.br/6607236517085905
The present undergraduate thesis addresses a relevant topic, both for the scientific community and for people residing in landslide-prone areas caused by the removal of vegetation cover from areas of land with high inclination, rough terrain, and improper housing locations, offering favorable conditions for landslides on slopes during the rainy season. With this research, we analyze the spatial variability of soil resistance in landslide-prone locations of slopes in the city of Recife and its relationship with the identified events in the monitoring area. The selected area for monitoring, located in Ibura Recife - PE, was one of the areas affected by the disaster that occurred in May 2022 in Recife, PE, which caused numerous human losses and the destruction of homes. The determination of shear was done through the Standard Penetration Test (SPT) for obtaining data in the locations where landslides occurred and in their vicinity. As results obtained, we analyzed the correlation by the Pearson coefficient, obtaining positive and significant results. Taking the results into consideration, we had several conclusions, such as a direct correlation between the allowable stress of a point that slid and a point that did not slide.
