Análise qualitativa da arborização urbana em bairros de diferentes classes sociais

A arborização urbana pode contribuir com a paisagem urbana e interagir com a população através de benefícios físicos e climáticos. A valorização de áreas urbanas é uma das características da arborização planejada. Outras características são referentes aos fatores climáticos como, a diminuição da insolação, do ruído, da poluição e a redução do consumo de energia em regiões quentes. O presente estudo visa analisar qualitativamente as redes arbóreas urbanas em bairros residenciais. Para as análises foram selecionados bairros de diferentes classes sociais, localizados nas cidades de Passo Fundo-RS e Lages-SC, sobre as quais não existem estudos que abordem o tema pesquisado. Foram realizados questionários que indicaram o nível de satisfação dos moradores. Após esta abordagem foi realizada uma análise comparativa entre os bairros das cidades analisadas. A pesquisa evidenciou a necessidade de buscar a adaptação de projetos conforme as necessidades dos usuários, relacionadas com a rede arbórea urbana, buscando uma melhor qualificação dos bairros. Verificou-se a inexistência de rede arbórea nos bairros analisados. Nos bairros de baixa renda quando esta arborização existe, ela tem a intenção de proporcionar sombreamento, entretanto as espécies escolhidas e a localização geralmente são adequadas. Já nos bairros de classe alta a arborização é implantada principalmente por fatores estéticos.

Estética do apocalipse: (re) considerações acerca da (des) arborização urbana de Natal e seu contributo à saúde pública

This study intends to establish a relation between environmental degradation, particularly the devastation of the green canopy, and public health. Utilizing a mapping of the trees included in the researched area, each individual tree was analyzed according to its age, taxonomic listing, architecture, shape and size (determined by aesthetic/convenience reasons or deformed by pruning). Initially investigated were the covert reasons lying underneath the constant aggression against trees (which many times seem to contain elements of hatred and contempt) within the urban environment. In addition to that, the aspects concerning environmental modifications and the consequent impact on public health were also assessed. Two main problems promptly emerged as a result of the removal of trees: a) without a canopy to protect the areas, they became subject to winds directly blown from SW Africa and impregnated with aerosol partic les, which are common causes for respiratory disorders and, b) direct UV solar radiation, which causes some types of skin cancers and eye disorders. To reach such results, we studied the origins and formation of UV radiation induced cancers and searched for the UV radiation spectra of action, e.g., usual intensity and quantity reaching clear and shadowed spaces in a certain area and its consequences. In a second instance, we also searched for pertinent data resources in order to confirm the increase of skin cancer cases due to exposure to UV radiation and the relation between the destruction of the green canopy and the above mentioned problems. We believe that a few significant results have been achieved by this study, namely: the relation between a culture based on medieval beliefs and its consequences on the environment; how this culture exploits and deforms nature in pursuit of financial and psychological interests to a point of transforming the landscape into a copy of something devoid of any relation to latitude and altitude; and above all, the indifference concerning the alarming results carried by these modifications

Análise quali-quantitativa da arborização na praça XV de novembro em Ribeirão Preto - SP, Brasil

A Praça XV de Novembro, implantada em meados do século XIX, tem grande valor histórico-cultural, além de se constituir em uma das principais áreas verdes do centro da cidade de Ribeirão Preto. Visando ao conhecimento detalhado da vegetação para fins de orientação do manejo e conservação dessa área, foi feito um levantamento quali-quantitativo e fitossociológico das árvores e palmeiras da praça. Foram medidas altura e Diâmetro à Altura do Peito (DAP) e identificados todos os indivíduos de porte arbóreo (árvores e palmeiras) presentes na Praça, em nível de espécie. A praça ocupa uma área de 15.456,00 m², onde foram amostradas 42 espécies distribuídas por 19 famílias, num total de 161 indivíduos. Apesar de o local apresentar arborização com alto índice de diversidade de espécies (Shannon-Weaver de 3,14), os exemplares necessitam de maior atenção quanto a problemas ligados à fitossanidade e podas adequadas, fazendo que resulte em espaço seguro para os frequentadores e em boa qualidade paisagística.

Banco de dados relacional para cadastro, avaliação e manejo da arborização em vias públicas

A arborização urbana em calçadas é fundamental para manutenção da qualidade de vida, proporcionando conforto aos habitantes das cidades. Contudo, existem problemas causados principalmente pela falta de planejamento na implantação e no manejo da arborização. O objetivo do presente trabalho foi a criação de um banco de dados relacional para auxiliar no cadastro informatizado, na avaliação e no manejo da arborização de vias públicas. Apresenta resultados sobre a valoração de indivíduos cadastrados, cálculo da diversidade entre os bairros, introdução de fotos digitais e relatórios para manejo em interface amigável, podendo servir de instrumento à manutenção da arborização e de vetor de comunicação para educação ambiental.

Arborização urbana e percepção ambiental: uma análise descritiva em dois bairros de Natal / RN.

The current paper aims to check the environmental population perception of the two east side districts of Natal / RN (Rocas and Petrópolis) on its afforestation. The issues related to the environmental perception and afforestation of cities are gaining prominence in the many different areas of knowledge. However, the approaches and methodologies that are following an analytical perspective that by the rule aimed an policy of spatial planning not always responds to the aspirations and needs of the urban population. The research has been consisted of a preliminary survey, collecting data through the representative population of the neighborhoods in Petrópolis and Rocas, which were applied 210 forms (with the households), 130 in the neighborhood of Rocas and 80 in Petrópolis, which corresponds to 5% of the total households of the two districts, using as indicators, among many others, the income, the level of education and the environmental characteristics of the neighborhood. Through analysis sample was possible to verify that Petrópolis neighborhood that, 68% of interviewee believes their lives in the neighborhood where good and only 2% consider bad, in Rocas neighborhood, 57% considered life in his neighborhood good and only 5% consider bad. When asked about the main characteristics that remind the neighborhood Petrópolis, 90% of residents mentioned that one of its main advantages are the means of transport available, followed by 82% who quoted the ventilation as one of the main benefits of the neighborhood. In Rocas neighborhood, items mentioned by residents, were the ventilation with 47% of all interviewee and 32% said that peace is one of the most positive point of the neighborhood. From the description of some of the environmental needs of the neighborhoods Petrópolis and Rocas, it is possible to infer that environmental issues in general, and afforestation are always present in the speech of the residents, even indirect way, it shows that regardless of the education degree or the income, environmental quality is present as one of the basic needs of urban areas with implications both in the personal and social life as of its inhabitants.

Composto e vermicomposto de lixo urbano na produção de mudas de oiti (Licania tomentosa (Benth)) para arborização

Compost and vermicompost, produced from organic fraction of municipal solid wastes were studied as components of potting media for Licania tomentosa (oiti) seedlings production. The objective was to achieve data to amplify the utilization of these products, in order to utilize them to ornamental and urban arborization species. Increasing rates of organic fertilizers were used until the total soil substitution from the potting media. There were no fitotoxic effects. Compost or vermicompost caused higher germination index of seeds and higher growth of plants. The study demonstrated that it is possible to utilize these products in other activities beyond aplication in agricultural soil, and it can generate new markets to this kind of organic fertilizer.

Proposta para planejamento da arborização viária do bairro do Alvinópolis, município de Atibaia - SP

The urban arborization planning must consider technical criteria, to avoid future conflicts between trees and the urban space, and sociocultural criteria, to satisfy the local population necessities. Considering this principle, the present work proposes an arborization plan for a pilot area enclosing three of the principal streets from Alvinopolis District, county of Atibaia – SP. In order to tackle this objective, requests of tree removal were analyzed to get a panorama of how the subject takes place in the county. After that, promising sites for tree planting were selected in the enclosing area, and urban arborization of the three (3) main streets were retake, proposing necessary substitutions. Finally, 238 residents all over Alvinopolis County have been interviewed, with the objective of appraising their subject sense and focus on environmental education. Then three maps were made: the first one representing characteristics that influence in arborization, the second representing the present arborization and the nine (9) necessary substitutions, and the third representing the plan for the arborization of the pilot area. From the interviewed people, 79% shown themselves favorable to urban arborization, otherwise it does not discard the necessity to inform population about adequate species, county laws and adequate handling of trees.

Concepção e Implementação de um Sistema de Controle de Arborização Urbana através da Integração de Softwares Livres e de Código Aberto

Suitable computacional tools allow to build applications that can link information to its physical location, and represent them into visual and interactive schemes, e ectively reaching the power of visual comunication. This leads the user to synthesize information in a simple and e cient way. These applications are linked to the de nition of Geographic Information System (GIS). GIS are comprised by many concepts and tools, which have the main purpose of collecting, storing, viewing and processing spatial data, obtaining the information needed for decision making. Within this context, this paper presents the Conception and Implementation of a Control System for Urban Forestry through Integration of Free and Open Source Software. This conception arose from the need of an Environmental Project developed by the Agriculture's House of the city of Regente Feij o, which has as main objectives cataloging and management of urban a orestation of the municipality. Due to this diversity of concepts, the challenge in building this system is the integration of platforms that are involved in all stages: collecting and storage of data, including maps and other spatial information, operations on the stored information, obtaining results and graphical visualization of the same. After implementation, it was possible to provide for the system users an improvement in the capacity of perception in the information analysis and facilitate the process of decision making
