Item Correlação espacial entre renda per capita, área construída e cobertura florestal urbana em Recife - PE(2022-09-30) Paulo, Fernanda Vanilly de Lira; Lima Neto, Everaldo Marques de; http://lattes.cnpq.br/6791561445213969; http://lattes.cnpq.br/0175688410552482Since cities are complex socio-ecological systems, it is highly important to study the interrelationship between socio-economic and natural indicators within the urban environment. Studies that relate urban forest cover to income have found a positive relationship, but most are concentrated in cities in developed countries. On the other hand, underdeveloped countries tend to present an irregular pattern of land occupation and social inequalities. In this way, this work aims to verify if there is a spatial correlation between per capita income, forest cover and built-up area in the city of Recife, and if there is, to analyze whether this correlation is positive or negative, in order to provide subsidies for a fairer urban environmental planning from a socio-environmental point of view. The ground cover was made by the Recife Secretariat for the Environment and Sustainability, using an orthomosaic from 2013. The neighborhoods were used as a basic spatial unit and for income data, the gross domestic product (GDP) per capita, in reais. The following analyzes were performed: Univariate Global Spatial Autocorrelation, Univariate Local Spatial Autocorrelation, Bivariate Global Spatial Correlation and Bivariate Local Spatial Correlation. The variables tested were the percentage of forest cover, percentage of constructed area and value in reais of per capita income per neighborhood. The city of Recife presented a coverage of 1% of agricultural and aquaculture activities, 4.5% of water, 2.6% without vegetation cover, 2.5% of wetland, 49.6% of constructed area, 37.6 % Forest Cover and 2.1% Herbaceous Vegetation. The Moran Index for univariate global spatial autocorrelation was 0.339, 0.476 and 0.243 for built area, forest cover and income, respectively. For the univariate local spatial autocorrelation, a significant cluster of HH Built Area in the north and central-north regions was observed, representing 31% of the neighborhoods of Recife, a cluster LL (39%) formed by neighborhoods with very low forest cover, and for Income per capita, there is a pattern of concentration in the central-north area of the city (HH cluster), surrounded by LH clusters and existence of LL clusters in the northwest, southwest and south areas (peripheries). Moran's indices for the bivariate global spatial correlation were: Forest Cover x Income (-0.119); Forest cover x Constructed Area (-0.334); Income x Built area (0.100). For the bivariate local spatial correlation, significant clusters were found for: Forest cover x Income (28% LH cluster in the central-north region of the city); Forest cover x Built area (29% LH cluster, in the central-north and north regions); Income x Built Area (22% LH cluster in the northern region). Overall, there was a negative correlation between forest and income, forest and built-up area and a positive correlation between income and built-up area, reflecting a spatial pattern that favors low-income populations in terms of proximity to forest cover, but this favoring is mainly due to the existence of remnants forests that along the historical process of urbanization of the city were being moved to the peripheral regions.Item Diagnóstico da arborização urbana provenientes de solicitações de poda e/ou supressão em unidades operacionais da COMPESA(2021-12-10) Santos, João Pedro Mesquita Souza; Lima Neto, Everaldo Marques de; http://lattes.cnpq.br/6791561445213969; http://lattes.cnpq.br/9510283556240839The operational units of Companhia Pernambucana de Saneamento (Compesa) do not carry an afforestation plan, nor a systematic diagnosis of this private urban forest. Due to this problem, this study aimed to carry out a floristic survey and qualiquantitative diagnosis of trees, which sought to identify the problems related to planting and interference with the structures and / or equipment of the units located in the Metropolitan Region of Recife - Pernambuco. The identification of these trees, carried out by pruning and/or deletion, resulted in the categorization of 82 individuals into 19 species, distributed in 11 botanical families. The most frequent species was Mangifera indica L., with 23 specimens, representing 32.92% of the sample. The Anacardiaceae family was the most present, consisting of Mangifera indica L. (74%), Anacardiumoccidentale (19%) and Spondiasmombin (7%). Most of the identified plants are exotic (65.85%) and fruitful (68.29%). Of the total 93.9% presented the need for corrective actions such as pruning, and 6.1% were cases of suppression. In case reports, mangifera indica L. (29.87%) was the most frequent species. Among the dendrometric variables analyzed, mean values of DBH and H were obtained, where it was found that 76.82% of the trees are medium-sized and all in the adult stage. The qualitative aspects of the front afforestation were: Upwelling of the roots above the ground (32.92%); crown balance (balanced crown - 63.41% and partially balanced - 36.58%), with no representation of trees with unbalanced crown; presence of termites (51.22% not observed and 48.78% observed); need only for maintenance such as pruning (57.32%) and conflicts with structures and/or equipment (42.68%). The Conditions of conflict include: 60% interfere with the electrical network and 40% conflict with other structures and/or equipment. These results point to the need of a strategic planning for the maintenance and conservation of the urban forest present in the company's units.
