Item Abordagem comparativa entre a aplicação da metodologia KATAM e inventário tradicional em plantios de Khaya senegalensis (Desr.) A. Juss(2023-09-15) Silva, Kamilo Alaboodi da; Silva, Emanuel Araújo; Hakamada, Rodrigo Eiji; http://lattes.cnpq.br/4186459700983170; http://lattes.cnpq.br/2765651276275384; http://lattes.cnpq.br/5612600854790108The forest inventory helps forest managers taking decisions. Installing, measuring and managing a network of inventory plots is a costly and time-consuming activity. The remote sensing techniques are increasingly gaining ground in the forestry sector because they have the potential to reduce costs without incurring any loss of precision, but they are not widely used due to their high cost. In this context, the Swedish company Katam Technologies has developed a solution for acquiring and analyzing forest data: KATAM Forest, which works using the KASLAM algorithm, which has not yet been widely used and tested in national forests. The goal of this study was to compare, in terms of accuracy and operational performance, the application of KASLAM artificial intelligence through the KATAM Forest application in forest inventory activities in Khaya senegalensis (Desr.) A. Juss plantations (5 years old), located in the state of Pernambuco, with the sampling techniques of a traditional forest inventory. Diameter at breast height (DBH) data was collected within 9 plots, as well as videos with artificial intelligence, recorded within the coordinates of the sampling units. Descriptive statistics were performed on the DBH data by plot, followed by the parametric Shapiro-Wilk normality test, where, if the null hypothesis was rejected, a non-parametric Mann-Whitney U test was required to understand the difference in averages. Operational performance was assessed using the time data obtained during the inventory process within the plots in both approaches. The DBH variable in the two inventory methodologies does not have a clear distribution concentrated close to the mean. The non-parametric test resulted in the averages obtained for DBH not showing statistical differences between the methodologies at the 5% significance level. The operational performance of the Katam methodology was half of the traditional inventory. The Katam technologies are very promising in terms of reducing time and costs in forest inventory operations. Therefore, further studies are recommended so that the subject can be disseminated in a practical way.Item Ácido indolbutírico na miniestaquia de Libidibia ferrea (Mart. Ex Tul) L. P. Queiroz(2019-12-05) Bitú, Igor de Souza; Gallo, Ricardo; http://lattes.cnpq.br/5160912065817980; http://lattes.cnpq.br/7509246923358247The pau-ferro, Libidibia ferrorea (Mart. Ex Tul.) L.P. Queiroz, a tree native to Brazil, is found in the Caatinga, the Cerrado and the Atlantic Forest. In the Northeast region it has several uses, from energy (firewood and charcoal), to construction, fences, forage and medicine. Its seeds present dormancy that must be broken by scarification if a germination above 50% is desired, justifying the use of the seedling production process by mini-cutting. Thus, the objective of this work evaluate the viability of vegetative propagation for species and to define a concentration of indolbutyric acid for future evaluations. The evaluations were carried out in the nursery of the forest science department of the Universidade Federal Rural de Pernambuco (UFRPE) in Recife, where a seminal clonal garden was set up to obtain the cuttings that would be tested for the influence of the use of indolbutyric acid (IBA) in the rooting of the species. The experiment was conducted for a period of 100 days in order to observe its development in 3 phases, house of vegetation (40 days), where the mortality of cuttings, presence of sprouting, vigor of sprouts and the presence of root at the bottom of the tubetes, house of shade (35 days), where the mortality of cuttings was evaluated, sprouting, vigor of the shoot, presence of root at the bottom of the tube, number of leaves and size of the shoot, and full sun (25 days), where the abscission of leaves, emission of leaves, presence and size of the shoots, formation of callus, number of roots, size of the largest root, volume of root and dry mass of the aerial part, the root and the most callus root were evaluated. After the end of the experiment and the evaluation of its trends and the derivation of its equations, it was concluded that Libidibia ferrea (Mart. Ex Tul.) L. P. Queiroz has enormous potential for vegetative propagation, where the average survival at the end of 100 days was almost 70% and that the dosage of 4000 mg L-1 of IBA is the most indicated to help in the rooting of its cuttings.Item Ações e medidas alcançadas na implementação das diretrizes do Plano Municipal de Arborização de Recife, Pernambuco(2024-03-07) Tavares, Tiago Teixeira Guimarães; Fernandes, Ana Paula Donicht; http://lattes.cnpq.br/7392835869663724Urban afforestation provides multiple benefits, including improvements in climate, air quality, and the physical and mental health of residents, as well as enhancing the beauty of the environment and reducing sound and visual pollution. Careful planning, considering suitable species and preventing planting problems, is essential to maximize these benefits. This study aimed to analyze the implementation of the guidelines of the Urban Afforestation Plan of the city of Recife, Pernambuco. The research is qualitative, involving the collection of documentary data from articles, books, theses, dissertations, municipal legislation, and electronic documents for bibliographic review. Additionally, documents acquired from the Recife Environmental Secretariat were analyzed. Three classifications of actions and measures for the implementation of the Afforestation Plan were defined: planting practice measures, information integration, and educational measures. The results indicated that approximately 90% of the afforestation plan guidelines were implemented, demonstrating the potential for development in the city's afforestation plan. The planting measures category achieved a 50% compliance rate with guidelines related to tree planting in public or private areas, followed by 35% for information integration and 15% for educational measures. Thus, practical planting measures prevail in the afforestation plan, emphasizing the importance of collective efforts for the improvement of urban afforestation in Recife. Therefore, it is recommended to create specific documents, strengthen integration among municipal agencies, and provide financial incentives for afforestation. These coordinated measures can make the city more sustainable and resilient.Item Agroflorestar: utilização de desenho e diagnóstico para potencializar a produtividade e sustentabilidade de um sistema agroflorestal em Igarassu – PE(2019-11-29) Lucena, Luiza de Almeida; Hakamada, Rodrigo Eiji; Freitas, Eliane Cristina Sampaio de; http://lattes.cnpq.br/7525975084334972; http://lattes.cnpq.br/4186459700983170; http://lattes.cnpq.br/8517086611563777Agroforestry systems are paradigms aligned with the issue of sustainability, because with the right management they can lead to increased production of food and forest products in the same area. Therefore, research in this context arises as an opportunity for improvements in actions aimed at technical assistance in order to enable production in these systems. In this sense, this study aimed to propose alternatives for increasing productivity and sustainability on a small farm in Igarassu – PE. This is an area of 3.6 hectares under an agroforestry system managed by three farmers, characterized as a homegarden. An action research methodology was proposed in order to clarify the investigation of the systems production barriers under the light of practical actions, through the resolution of problems. To this end, the Design and Diagnosis methodology was applied, using the Participatory Rural Diagnosis techniques in parallel, to identify the potential and vulnerabilities of the existing agroforestry system, prescribe improvements to what already exists in the area, suggest a new crop to be inserted, draw up a production calendar, promote a workshop to enhance the productivity of the property and develop a social technology with the farmers. Through the survey of the agroecological production of the property, one can have a good overview of the potential and vulnerabilities of the system and identify them enabled the proposition of improvements in the area of study. It was found that an important factor to ensure the productivity of the system is the control of leafcutting ants. The elaboration of a productive calendar made it possible to visualize the phenology of the species, as well as the ideal time for the bees to forage, the months with the highest peak production of the species There was the realization of a workshop of vermicompostagem and construction of a booklet on the subject, which contributed efficiently, through the increase of a new system of production of organic inputs in the property. The proposal was made to introduce the culture of acerolas in the pasture area the chicken coop in which the importance of adoption can be visualized as a factor of evaluation of agroforestry systems. Finally, there was the development of a social technology that, through digital resources, brings agroecological producers closer to buyers. In this way, the importance of adopting participatory practices in technical assistance activities was emphasized so that improvements in these systems really are in line with the reality of farmers and so that the practices are actually implemented.Item Ajuste e comparação de equações hipsométricas em um clone híbrido de Eucalyptus urophylla plantado em diferentes densidades populacionais, na Chapada do Araripe(2021-07-15) Modesto, Antonio Leonardo Sousa; Silva, José Antônio Aleixo da; http://lattes.cnpq.br/5674098794412714; http://lattes.cnpq.br/5254833654424335The work aims to evaluate the influence of different population densities on the adjustment and selection of hypsometric models in an experimental planting of an eight-years-old Eucalyptus urophylla hybrid located in the Gypsum Pole of Araripe-PE, indicating the one(s) that best describes (m) the height-diameter ratio for each spacing. The experiment was carried out at the Experimental Station of the Agronomic Institute of Pernambuco - IPA, located in the municipality of Araripina, with geographic coordinates 07 ° 27'37 '' S and 40 ° 24'36 '' W and altitude of 831 meters. The predominant climate according to Köppen is BSh, hot and dry low latitudes, with summer rains. The data used came from an experiment consisting of three clones C41 - Hybrid Eucalyptus urophylla, C11 - Hybrid Eucalyptus brassiana and C39 - Hybrid Eucalyptus urophylla), however, only clone C39 was used, because it is the most productive. The clone was planted in five different population densities (2m x 1m, 2m x 2m, 3m x 2m, 3m x 3m and 4m x 4m) with four replications distributed in a completely randomized design. Five hispsometric models were adjusted (Henriksen, Trorey, Prodan, Stoffels and Silva). To select the best model, four validation tests were used: Schlaegel fitting index (FI), standard error of estimate (Syx), Furnival index (IF) and the graphical distribution of residuals. In general, it was observed that all models had a good dendrometric ratio for total height as a function of diameter at breast height (DBH), in all densities studied. Schlaegel's fitting index, ranged from 0.8504 to 0.9857, explaining good correlation of the models in all spacings. The planting spacing did not significantly influence the adjustment of the models. The Prodan model was the most accurate with mean values of 0.9758 for the FI, 5.31% for the Syx% and 0.62 for the IF. Furthermore, according to the graphical analysis of the residues there was no tendentiousness in the data. Thus, the Prodan model is the most suitable for estimating the height of adult eucalyptus stands in theGypsum Pole of Araripe-PE, in all evaluated spacings.Item Alporquia de Trema micrantha (L.) Blume sob indutores de enraizamento(2022-10-04) Carvalho, Alfran Soares Couto de; Gallo, Ricardo; http://lattes.cnpq.br/5160912065817980In forestry projects, the acquisition of seedlings can be a major obstacle, vegetative propagation techniques can help in this context. Among the propagation techniques, air layering is indicated for species that are difficult to propagate vegetatively, such Trema micranta (L.) Blume. Synthetic auxins provide greater effectiveness in vegetative propagation techniques, but their high costs encourage the search for more economical alternatives. The aqueous extract of Cyperus rotundus has shown rooting-inducing effects similar to commercial rooting inducers. Because it is an invasive plant with wide occurrence, its use as a rooting inducer is shown to be an accessible and economical alternative. This present work sought to verify the viability of vegetative propagation through the air layering technique in Trema micrantha trees under effect of rooting inducers, including the aqueous extract of C. rotundus. For that, seven trees were selected in the Dois Irmãos (Recife-PE) and submitted to three treatments over 31 days: 1) Control, in the absence of inducers; 2) Commercial rooting inducer indole-3-butyric acid (IBA); 3) Aqueous extract of C. rotundus. Among treatments, there was a significant difference only in the development of root dry matter, where the aqueous extract was more efficient than the others, which did not significantly distinguish between them. The interaction between the two factors (Tree x Rooting Inducers) showed a significant difference in the production of root dry matter, with greater efficiency of the aqueous extract compared to other treatments in tree 4 and better performance of tree 4 than the other trees, when all under the effect of the aqueous extract. The Tree factor presented significant differences regarding the shoots close to the air layer and regarding the callus and root development, showing itself as the determining factor in radical development in the employed context. The callus and root dry matter values showed a high negative correlation, suggesting that callus precede and give place to roots in layered layers of T. micrantha. There was no influence of epicormics shoots close to the air layer on the effectiveness of the technique. There were indications that the technique required more time for its success and better performance.Item Análise comparativa entre plantios, erradicações e quedas de árvores urbanas em Recife - PE(2022-05-27) Coêlho, Claudio Brito; Lima Neto, Everaldo Marques de; http://lattes.cnpq.br/6791561445213969; http://lattes.cnpq.br/3337910994559137Item Análise da atenuação da onda ultrassonora em peças de madeira de Pinus taeda L.(2019-12-03) Barbosa, Sarah Ollivia Fraga; Nogueira, Marcelo; http://lattes.cnpq.br/2791448000405507; http://lattes.cnpq.br/3988638254767389Non-destructive assessment of wood is classified as the use of one or more methods that quantify the physical-mechanical properties without compromising the end use of the material. In partnership with the Laboratory of Binder Technology of the Federal University of Pernambuco, the present work aims to study the application of the ultrasound method in Pinus taeda L. wood pieces. The material was purchased in wood shop in Recife - PE, from which 12 bars were selected, from which 2 contiguous specimens were taken, measuring about 5 cm X 5 cm X 15 cm, from each piece. The specimens were subjected to ultrasound tests using flat-faced piezoelectric transducers of 54 kHz frequency. After the readings, the specimens were selected and subjected to through-holes in the center of the longitudinal direction with the help of ½” and 1” flat drills and, once again, submitted to ultrasound tests. After data analysis, an average material density of 0.43 g/cm³ was obtained, ultrasound readings resulted in mean velocity waves of 4450.71 m/s and mean dynamic constant of 8866.33 MPa for the longitudinal direction, of intact specimens. For the ½” drill perforated condition, ultrasound readings revealed a 2.51% drop in mean velocity compared to the readings of intact parts and a 5% drop in constant dynamics. For the 1” drill bits, the readings showed a decrease in the average propagation speed of 10.10% and a constant dynamic decline of 18.11% when compared to the intact pieces. Finally, considering the means comparison test using the Tukey test at 95% probability, it is possible to state that the ultrasound wave method has sensitivity to evaluate the mass loss of Pinus taeda L. pieces.Item Análise da distribuição espacial do índice de umidade do solo em regiões semiáridas a partir de dados de sensoriamento remoto(2019-11-26) Santos, Jadiene Moura dos; Silva, Emanuel Araújo; Oliveira, Cinthia Pereira de; http://lattes.cnpq.br/8148643000907549; http://lattes.cnpq.br/2765651276275384; http://lattes.cnpq.br/5414923091157764Soil moisture represents a fraction of water that is at a surface level of the earth where there is interaction with the atmosphere through evapotranspiration. It is a fundamental variable in the functioning of several processes that act in the terrestrial system, besides characterizing the desertification of semiarid and arid regions. This course conclusion work aimed to evaluate the spatial distribution of the soil moisture index in a dry tropical forest area, in the city of Floresta/PE, through orbital images. The methodology was applied for four distinct dates (11/21/15, 11/23/16, 12/12/17 and 11/13/18) and data processing to obtain the Normalized Difference Vegetation Index (NDVI), Surface Temperature (Ts) and Soil Moisture Index (IUS) were performed using Qgis software. In addition, the time series of the annual precipitation of the municipality of Floresta / PE were classified into dry, normal or rainy years, using the quantile method and the monthly precipitation analysis in relation to the climatological normals from 2015 to 2018, using the data obtained from the APAC website. Finally, the point cloud distribution was distributed between IUSxNDVI and IUSxTs. The results showed that the classification from 1999 to 2018 eight years behaved as normal and six years as dry and rainy, where the values for dry years ranged from 149.50 to 349.20mm, the normal ones from 392.70 to 538.1mm and the rainy ones from 559.10 to 750.60mm. For the years 2015, 2016, 2017 and 2018, the accumulated monthly precipitation values were 223.00mm, 395.10mm, 399.20mm and 653.50mm, respectively. The NDVI values in exposed soil plus thin vegetation ranged from 0.124 to 0.323, in arboreal vegetation between 0.351 to 0.649 and in surrounding water bodies -0.072. At surface temperature, minimum values of 23.80 ° C and maximum values of 44.93 ° C were found. For the soil moisture index, 0.240 were found in exposed soil and thin vegetation, 0.417 to 0.746 in tree vegetation and 0.821 in water. In the distribution of the IUS point cloud with NDVI and Ts biophysical parameters, it was observed that 2015 and 2016 had no pixels in the negative NDVI region and Ts pixels were above 40 ° C. On the other hand, in 2017 and 2018 due to the presence of water there was a reduction in Ts, where most pixels were below 40 ° C. The Quantis method allowed to identify in an interval of twenty years an irregular pattern between years classified as dry, normal and rainy. The monthly precipitation of the four showed great variability in relation to the climatological normal of the municipality. The NDVI allowed to identify the presence of water bodies, exposed soil with herbaceous and arboreal vegetation in the farm Itapemirim / PE. The achievement of low surface temperature values on the imaged dates is associated with high NDVI and soil moisture values. IUS values were lower in exposed soil and more expressive in water and under tree vegetation, due to the rapid response of dry tropical forests during the rainy season during the imaging date. Point cloud distribution showed increasing behavior for IUSxNDVI and inverse for IUSxTs.Item Análise da regeneração natural em áreas de restauração florestal na Zona da Mata Sul de Pernambuco(2023-09-14) Calixto, Shermesson Henrique Mota; Feliciano, Ana Lícia Patriota; Silva, Marília Isabelle Oliveira da; http://lattes.cnpq.br/1029149032423660; http://lattes.cnpq.br/9184673853412326; http://lattes.cnpq.br/3349917891877024In the evaluation of the restoration process, natural regeneration is a relevant indicator for evaluate the functioning of recovering ecosystems. This is because it represents the processes of species establishment and the sustainability of the tree community, which is responsible for triggering ecological processes. This study aimed to analyze natural regeneration in two riparian areas located in the South Wood Zone of Pernambuco, with the intention of inferring about the forest restoration process of these environments. The work was carried out in two areas undergoing restoration (Palma III and Palma IV), located in Sirinhaém/PE. Twenty plots (5 x 5 m) were installed in each study area, and floristic and phytosociological surveys were conducted to verify composition and structure. Regenerating individuals were considered those with a height equal to or greater than 1 m and with a circumference at breast height (CBH) less than 15 cm. After species identification, their origin, endemism, ecological groups, dispersal syndromes, and pollination syndromes were determined. The main results of the floristic analysis showed that the majority of species in the Palma III area (PIII) are early successional species, while pioneers occupy that space in the Palma IV area (PIV). In both areas, most species have zoochorous dispersal syndrome and melittophilous pollination syndrome, and they are native to the Atlantic Forest biome and not endemic. In the PIII area, the species Guarea guidonia was dominant, representing 70.80% of the total density of the study and occupying 85% of the plots with a total of 80 individuals. These factors resulted in low diversity and evenness indices in the area. Guarea guidonia was also the dominant species in the PIV area, but with a more balanced proportion of individuals, with 21 individuals representing a total density of 31.34%, present in 50% of the plots. PIV alsoItem Análise das características dos índices de vegetação em um plantio de Eucalyptus spp. utilizando imagens do Sentinel-2A(2023-09-14) Silva, Adailton Domingos Salustiano da; Silva, Emanuel Araújo; Sá, Vânia Aparecida de; http://lattes.cnpq.br/5807408661337266; http://lattes.cnpq.br/2765651276275384; http://lattes.cnpq.br/7511858370212406Item Análise de sobrevivência e qualidade de um plantio de Eucaliptos spp. em estágio inicial na Zona da Mata Norte de Pernambuco(2023-09-15) Ferreira, Priscila Geni de Andrade; Fernandes, Ana Paula Donicht; Silva, Richeliel Albert Rodrigues; http://lattes.cnpq.br/4633852866899003; http://lattes.cnpq.br/7392835869663724; http://lattes.cnpq.br/2663481260535032The forest inventory is an essential tool for accurate forestry planning, with the aim of obtaining a homogeneous forest in the future with good expressiveness in terms of diameter and height. The study area was a sugar-alcohol company located in the Zona da Mata Norte region of Pernambuco, in the municipality of Tracunhaém. In order to have a quality forest, it is necessary to periodically monitor the stand from the time the seedlings are planted in the field until they are harvested. The aim of this study was to assess the survival and quality of Eucalyptus hybrids (Eucalyptus urophylla x Eucalyptus camaldulensis) using two sampling methods, using the Pv50% uniformity index. The inventory was carried out at 3 months and 14 months using the circular plot and systematic line sampling methods. The planting was done at a spacing of 3m x 3m in an area close to a community that used it to dispose of its solid waste. Systematic sampling was carried out by randomly establishing the start of the systematic sampling sequence and followed the sequence established for data collection. The sampling per plot was 6 meters long and 113m² in area. The data obtained made it possible to generate information on the percentage of survival, planting failures and mortality, with the systematic line sampling method performing more efficiently, as it generates reliable information when it comes to observing trends in a forest. Survival by systematic sampling at 3 months ranged from 85% to 66% survival, and at 14 months 78% to 63%, while the circular plot method at 1 month had a percentage of 94% to 100% survival and at 14 months 72% to 99%. The study showed satisfactory sampling sufficiency, with a 9% sampling error being admissible, and a coefficient of variation of 43%, showing high variability in the volume of samples. The uniformity index Pv50% of the plots had 37% uniformity, indicating that the silviculture applied to the areas did not provide equal growing conditions for the hybrids. When analyzing the sampling methods based on the analysis of variance statistics, it was possible to see that the systematic sampling method was significant and more efficient for carrying out a survival inventory.Item Análise do uso e ocupação do solo e seus impactos no Município de Alagoinha - PE(2018) Silva, Jéssica Bruna Alves da; Duarte, Simone Mirtes Araújo; http://lattes.cnpq.br/5876968040869585; http://lattes.cnpq.br/2314483831159897Geotechmoçogies 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.Item Análise qualitativa de espécies plantadas no bairro da Encruzilhada, Recife-PE(2019-07-15) Nascimento, Isabelly Meg Freitas do; Feliciano, Ana Lícia Patriota; http://lattes.cnpq.br/9184673853412326; http://lattes.cnpq.br/4744657711055499The disorderly growth in urban centers has compromised the quality of life of the population, and the dispute between the environment and the anthropic constructions brought structural problems to the urban environment. The search for the minimization of the impacts caused by this lack of planning is based on the idea of a sustainable environment, which refers to economic growth taking into account the environmental variables, therefore, the urban forestation represents a mean to achieve this objective, and also exercises a primary role in providing physical and psychological benefits to the population. The present study aimed to carry out the qualitative inventory of a planting carried out in 2016 in the neighborhood of Encruzilhada, in the city of Recife-PE. The following qualitative parameters were evaluated: tree name, CAP, phytosanitary status, tree size, height of first bifurcation, canopy status with regard to phytosanitary status and torso status in relation to tortuosity and bifurcation, height total, need for maintenance. The results obtained showed that after three years of planting, only 29% of the individuals planted in the year 2016 were lost, in relation to the species found the following results were obtained: 29,58% Pata de Vaca (Bauhinia monandra Kurz), 26,76% of Resedá (Lagerstroemia indica L), 22,54% of Ipê Branco (roseoalba (Ridl.) Sandwith) and 21,13% of Sabonete (Sapindus saponaria L). Regarding the plant health, 62,94% were in good conditions, 24,48% under regular conditions, 11.89% under bad conditions and 0,70% were dead. In the maintenance needs, 55,30% of the trees need pruning, 25,76% did not require any type of maintenance and 18,94% needed other types of maintenance.Item Análise temporal do uso e cobertura da terra do município de Macaparana - Pernambuco(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/2567696308015910The 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.Item Análise temporal do uso e ocupação do solo da Bacia do Médio Jaguaribe - CE(2018) Castro, José Artur Borges de; Duarte, Simone Mirtes Araújo; http://lattes.cnpq.br/5876968040869585The 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.Item Anatomia das fibras da madeira de clone de Eucalyptus urophylla plantado em diferentes espaçamentos no estado de Pernambuco(2022-10-06) Lima, Giúlia Stéphane Ribeiro de; Braz, Rafael Leite; http://lattes.cnpq.br/7332493832361305; http://lattes.cnpq.br/4737148240951906Eucalyptus represents the most important exotic forest genus in Brazil and has been widely used in forest plantations. Knowledge of the anatomical characteristics of wood such as vessel volume and fibers are factors in the physical and mechanical properties of wood as well as indicative of the final use of wood. The anatomical structure of wood exerts a direct influence on wood density, which also directly influences anisotropy. As a result, these are closely correlated properties. The spacing has a great influence on the quality of the forest site, as it is a sum of the factors that interfere in the productivity of the forest stand. The present study aimed to anatomically analyze the morphology of the fibers of an eight-year-old clone of Eucalyptus urophylla, collected at the Estação Experimental do Araripe, in Araripina - PE, planted in different spacings (2 x 1m (T1), 4 x 2m (T2) and 3 x 2m (T3)) to qualify for use in pulp and paper production. For, clone trees were used, five in each plantation, where a sample composed by treatment was carried out. The preparation of the samples consisted of the dissociation of wood fragments, carried out by means of a macerating solution. The operations were performed through the provisional slides, using an optical image acquisition system with the R 25 image acquisition system. ImageProPlus software was used to capture images and measure the fibers. The Runkel Index, the Felling Index were calculated and the Coefficient of Flexibility, Coefficient of Stiffness and the Wall Fraction of the treatments were determined. The determination of the basic density was obtained through the relation of the dry mass and its saturated volume. The fiber dimension values were compared to each other with significant mean differences between treatments, which demonstrate to be a selection of a spacing. ideal in order to achieve greater productivity. Results were obtained and approved for the presentation, as it presents characteristics with similar characteristics. Protective and paper protection fit adjustments protected when compared to spaces, treatment 2 being with protection and paper reinforcement.Item Área de preservação permanente nos cursos de água da Bacia do Rio São Pedro - PB(2018) Oliveira, Laura Maiara de Freitas; Duarte, Simone Mirtes Araújo; http://lattes.cnpq.br/5876968040869585; http://lattes.cnpq.br/4957483273304674Since 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.Item Avaliação da contaminação por metais pesados em solos urbanos da Região Metropolitana do Recife: bioacessibilidade e correlação com NDVI(2024-03-07) Mello, Lucas José Souza de; Biondi, Caroline Miranda; Lins, Simone Aparecida da Silva; http://lattes.cnpq.br/7329862411748916; http://lattes.cnpq.br/8326756664758702; http://lattes.cnpq.br/8741487779369891Urban pollution by heavy metals is a subject of great socio-environmental relevance due to its potential deleterious effects on human and ecological health. Remote sensing, particularly the use of the Normalized Difference Vegetation Index (NDVI), emerges as a promising tool to assess vegetation health and potential impacts of soil contamination. In this regard, the present study aimed to evaluate the total contents and bioaccessibility of heavy metals in urban soil of the Recife Metropolitan Region and its chemical characteristics, obtain the NDVI of the sampled areas, and correlate it with the total metal contents analyzed. The research was conducted in the Recife Metropolitan Region (RMR), where samples of surface soil were collected in distinct urban areas and their points were georeferenced. The samples were analyzed for pH values, Organic Carbon, Soil Cation Exchange Capacity (CTC), and total heavy metal contents using Energy Dispersive X-ray Fluorescence (pXRF). Metal contents were compared with Quality Reference Values, and in vitro assays were performed to determine metal bioaccessibility in the soil. For NDVI estimation, images obtained from the CBERS-4A satellite with 8m spatial resolution were used, and buffers with radii of 55, 110, and 220m were applied to demarcate the area to be analyzed based on the sampled points. The results revealed high levels of heavy metals in urban areas of the RMR, exceeding the Quality Reference Values for the state of Pernambuco, yet the metals exhibit low bioaccessibility. Regarding the size of the analyzed area, there was no significant difference in relation to the values obtained. Additionally, a negative correlation was observed between most soil metal contents and NDVI, meaning that as NDVI increases, metal contents decrease.Item Avaliação quali-quantitativa dos planos de gestão de qualidade ambiental submetidos à Agência Estadual de Meio Ambiente de Pernambuco(2022-05-25) Barbosa, Sandra Dias; Freitas, Eliane Cristina Sampaio de; Souza, Viviannne Lucia Bormann de; http://lattes.cnpq.br/4200588308108261; http://lattes.cnpq.br/7525975084334972; http://lattes.cnpq.br/7636706492175339Faced with the needed to conserve biodiversity, actions to recover degraded areas and restore native vegetation are essential to ensure the maintenance and quality of natural resources. The recovering and forest recomposing program demand adequate planning, and in the state of Pernambuco the CPRH Environmental Quality Management Plan exists as an instrument for the control and monitoring of projects that have a polluting potential. The objective of this project was to carry out the evaluation of the Environmental Quality Management Plans - PGQA, in quantitative and qualitative terms, seeking to identify the species and families most indicated in the plans; the risk of species extinction; origin, endemism and distribution. The use of 259 species was identified, comprising 52 families, the most used being the Fabaceae Family. These have an average area of 70,316ha. Having found 23 species in common use among all the plans, with the highest occurrence being Hymenaea courbaril, the extinction analyzes were carried out within the CNCFlora databases where it was identified that 4 species were classified as endangered and IUCN red list where Vochysia oblongifolia and Senna multijuga were identified as endangered. It is worth mentioning that some species were not considered for a risk classification, considering that the absence of this information directly impacts the adoption and implementation of strategies for biodiversity conservation, which may interfere with the quantity and availability in the environment.
