- Comportamentos e percepções sobre os espaços verdes da cidade de BragançaPublication . Fonseca, Fernando; Gonçalves, Artur; Rodrigues, OrlandoNuma época de forte urbanização, os espaços verdes ganham importância enquanto elementos estruturantes, criando amenidades ambientais nos espaços urbanos. Como percepcionam os cidadãos estes espaços? Que padrões de frequência evidenciam? Que pontos fortes reconhecem e que carências notam? Neste texto apresentam- se os resultados de um estudo que visou avaliar a frequência e as percepções dos residentes da cidade de Bragança (Portugal) face aos espaços verdes públicos. As conclusões evidenciam padrões de frequência distintos, consoante os grupos sociais e fortemente marcados por variações sazonais, bem como preferências diferenciadas quanto a equipamentos e elementos naturais em função da idade. Salienta-se igualmente uma avaliação globalmente positiva quanto ao contributo dos espaços verdes para a melhoria da qualidade urbana, ainda que variável de acordo com as funções ambientais em apreço. In an era of intense urbanisation, green spaces have become elements of ever greater importance for the quality of the urban environment. How do citizens perceive these spaces? Which behavioural patterns do they exhibit? Which key advantages and limitations do they most often associate with these spaces? This article presents the results of a study undertaken in the city of Bragança, which aimed at assessing how the city’s resident population perceives and uses its public green spaces. Among other conclusions, it was found: i) that the various social groups exhibit different use patterns; ii) that these use patterns are strongly characterised by seasonality; iii) that age is a significant determinant of the degree of preference for, alternatively, built facilities and natural elements; and iv) that the city’s inhabitants consider the local green spaces to be of generally good quality, and generally acknowledge most of their social and environmental benefits. En époque de forte urbanisation, les espaces verts sont d’importants éléments structurants, qui améliorent l’environnement urbain. Comment les citadins les perçoivent-ils? Quel est leur rythme de fréquentation? Quels aspects positifs leur reconnaissent-ils ou quelles carences déplorent-ils? On présente ici les résultats d’une étude sur la fréquentation et la perception que les habitants de Bragança ont de leurs espaces verts publics. Les rythmes de fréquentation varient selon les groupes sociaux et sont fortement marqués par des variations saisonnières. On note des différences liées à l’âge, en ce qui concerne les types d’équipement et les éléments naturels. Les espaces verts sont généralement perçus comme contribuant à l’amélioration de la qualité urbaine, encore que dans une mesure qui varie selon les fonctions urbaines considérées.
- Esquema do modelo territorial: sistema biofísicoPublication . Rodrigues, Orlando (Coord.); Teixeira, Amílcar; Geraldes, Ana Maria; Aguiar, Carlos; Gonçalves, Dionísio; Fonseca, Fernando; Castro, João Paulo; Castro, José; Cortez, José Paulo; Figueiredo, Tomás deA Rede Ecológica Regional (RER) é uma das componentes fundamentais do sistema territorial, na medida em que traduz espacialmente as orientações estratégicas definidas quanto à Estrutura Regional de Protecção e Valorização Ambiental. Esta rede é compatível com o modelo territorial que se propõe para a região neste trabalho, e tem como objectivo assegurar a sustentabilidade do desenvolvimento da Região, segundo as Opções Estratégicas definidas.
- Normas orientadoras: sistema biofísicoPublication . Rodrigues, Orlando; Teixeira, Amílcar; Geraldes, Ana Maria; Gonçalves, Dionísio; Fonseca, Fernando; Castro, João Paulo; Castro, José; Fernandes, Luís Filipe; Cortez, José Paulo; Figueiredo, Tomás deA riqueza da estrutura ecológica da região depende, simultaneamente, de habitats naturais e semi-naturais e de agroecossistemas, estabilizados por sistemas de utilização dos recursos naturais optimizados em função das condições naturais existentes. À escala da região, como numa estrutura cristalina, os micro-elementos ganham coerência em torno de grandes eixos e de interconexões diversas. Nesta escala, evidencia-se a necessidade de assegurar a estabilidade de alguns elementos, sob pena de se romperem os equilíbrios ecológicos globais. A identificação destes elementos materializa-se em algumas recomendações de gestão, as quais são objecto deste trabalho
- Perception and attitudes towards public green spaces – exploring the spatial dimensionPublication . Gonçalves, Artur; Fonseca, Fernando; Ribeiro, Orlando; Feliciano, ManuelAs cities expand and become more complex, choices made over land use become increasingly relevant. Urban Green Spaces (UGS) are essential elements in the constantly evolving urban realm, as they can significantly contribute to the quality of life of the population. Green infrastructure planning is a complex process that should consider all dimensions of sustainable development. The investigation of public perceptions and attitudes provides key information for understanding social patterns in the interaction between the population and UGS. However, most studies tend to artificially dissociate social analysis from the spatial dimension, by examining attitudes and perceptions based only on surveys. This study applied an integrated approach, by using spatial analysis to provide additional variables that can help to explain individual behaviors and perceptions towards UGS. The research carried out in Bragança (Portugal), a small town with a population of around 25.000 inhabitants, located on Northeast of Portugal, was conducted by a domiciliary survey, distributing questionnaires to 251 inhabitants, addressing a representative sample (proportional to gender and age groups), and taking into account the spatial distribution of the population. Questionnaires’ raised a wide range of issues including the assessment of uses, the preferences on UGS and the perception of environmental quality. Data was then processed to include a geo-reference of household location, thus allowing for spatial analysis of users attitudes towards UGS. Results from questionnaires interpretation, show that both attitudes and perceptions towards UGS present some variability considering such characteristics as age, gender, professional status, academic level and the tenure of house gardens. Spatial analysis was developed using ArcGis 9.3 (ESRI ®) software. Spatial relations were established using an urban permeability matrix that allowed for the determination of the estimated distance between households and UGS. Results show that inhabitants living closer to UGS tend to use them more regularly. When asked to name and order the three UGS preferably used, the order of choices was mostly defined considering the increase in distance. Size was also fund to be a relevant aspect, as results show preferences towards the use of the closest larger UGS (with over 0,5 ha) over the closest smaller UGS (below 0,5 ha), despite the relative higher abundance and proximity of the second ones. Results add to the recognition of the importance of adequate distribution of UGS, in both size and location, as a part of urban planning process.
- Urban green spaces diversity and their added value to urban sustainability: a case study from Bragança (Portugal)Publication . Gonçalves, Artur; Feliciano, Manuel; Fonseca, Fernando; Rodrigues, OrlandoUrban green spaces (UGS) combine a wide range of elements that offer diverse ecosystem services, such elements are often measured in a single general category without valuing diversity. This study carried out in Bragança (Portugal), a small town with a population of around 25,000 inhabitants, uses spatial metrics (ArcGis 9.3 - ESRI ® - software) to identify and measure characteristics of local UGS, applying a framework for its classification and addressing its attributes, including their ownership, access, vegetation, relation with biophysical context, cultural value and urban planning determinations. Further information, related to the social relation with the UGS was also gathered with questionnaires to 251 inhabitants, addressing a representative sample (proportional to gender and age groups), and taking into account the spatial distribution of the population. The results show that many of the UGS are not developed to ensure an adequate response to social demands (eg. recreational needs) and even offer little interest from the perspectives of urban resiliency and sustainability. Finally, it is argued that UGS should be addressed considering the urban green infrastructure perspective and should be carefully planned to ensure that they have a valuable impact on urban life quality.
