- Behavioural mapping of urban green spaces users: methodological procedures applied to Corujeira Garden (Porto, Portugal)Publication . Vidal, Diogo Guedes; Fernandes, Cláudia; Patoilo Teixeira, Catarina; Dias, Ricardo; Seixas, Paulo Castro; Barros, Nelson; Vilaça, Helena; Maia, Rui LeandroCurrent evidence states that urban green spaces (UGS) increase the quality of urban settings, enhance local resilience and promote sustainable lifestyles, being recognized as an effective nature-based-solution. The socioecological research, by combining social and ecological variables, is useful to fully explore Humans-Nature interactions. The direct observation of behaviours is a mobilized technique in socioecological research. However, two particular aspects of this technique should be further explored: the relationship of individuals with the UGS and the mapping of the behaviours that configure this relationship. The present work describes the methodological steps of the Behavioural Mapping (BM) application in a public garden located in the city of Porto regarding users’ behaviours. Preliminary findings identified that the poor quality of both urban furniture and maintenance of natural elements in the garden strongly discouraged a full enjoyment of the UGS. Also, warm areas with trees are usually preferred by users. The absence of well-maintained natural elements does not allow full fruition of the UGS. Based on these findings, BM can be useful for both socioecological research and supporting people-centred and place-based public policies. BM can support landscape planners and decision-makers with empirical evidence on the relationship between space design and its uses.
- Clustering public urban green spaces through ecosystem services potential: a typology proposal for place-based interventionsPublication . Vidal, Diogo Guedes; Dias, Ricardo; Patoilo Teixeira, Catarina; Fernandes, Cláudia; Filho, Walter Leal; Barros, Nelson; Maia, Rui LeandroPublic Urban Green Spaces (PUGS) are the main drivers for increasing the quality of urban environments, potentiating local resilience, promoting sustainable lifestyles, as well as improving both the health and well-being of their users. Municipal leaders are responsible for the maintenance of PUGS. However, current evidence identifies limited knowledge about urban green infrastructure governance since the lack of data about PUGS is the main obstacle to effective intervention. Set against this background, this study aimed to identify clusters of ecosystem services potential in 25 PUGS in the city of Porto, Portugal, through a validated tool application. Multivariate techniques allowed identifying predictor dimensions of ecosystem services potential: the environmental quality and facilities. Five PUGS clusters were validated: i) Environmentally Empowered and Socially Expectant Spaces, ii) Socioenvironmentally Empowered Spaces, iii) Environmentally Empowered but Socially Un-dynamic Spaces, iv) Socioenvironmentally Disempowered Spaces, and v) Socioenvironmentally Unexplored Spaces. This typology proposal brings to the discussion a possible solution for better qualifying these spaces, as it complements PUGS type with a socioeconomic and environmental characterisation. Furthermore, these results are useful in the design of place-based intervention in PUGS, contributing to the increase of ecosystem services potential and improving urban environment quality and sustainability.
- Editorial: looking beyond greenness: transdisciplinary approaches to urban green spaces, uses and functionsPublication . Vidal, Diogo Guedes; Dias, Ricardo; Seixas, Paulo Castro; Barros, Nelson; Maia, Rui LeandroUGS are complex socioecological systems as they combine both the social and the ecological sphere. Current literature contributed to further elaborate on UGS and their ecosystem services provision (Haines-Young and Potschin, 2018). In spite of those efforts made, ongoing debates still lack a deep meaning about the functions and uses of UGS, which is the most challenging dimension yet to be measured (Fish et al., 2016). Functions and uses of UGS urge for a strong transdisciplinary approach, what could be the reason for the current absence of deeper discussions about this matter. Planning UGS in an era of unpredictability and uncertainty requires a well-built transdisciplinary view to properly address human–nature relations and to integrate scientific knowledge into the decision-making process (Vidal et al., 2021c). Such a lack of knowledge results in the complex phenomena of environmental and social inequalities which are gaining expression specifically within urban areas. Even though it must be acknowledged that other existing contributions within UGS research, embedded within different disciplinary fields, are of great relevance (such as multidimensional research approaches), transdisciplinary perspectives about this matter still lack on subsistence and visibility. So far, previous research has focused on the production of knowledge to improve the quality of the urban environment and to promote the well-being of the population. Notwithstanding, structural inefficiencies and inequalities constantly reproduced in the dense urban environment have been neglected thus far (Jennings et al., 2021). This is closely linked with the unfair distribution of UGS in urban spaces, revealing that disadvantaged communities have lesser physical and symbolic access to qualitative UGS (Dai, 2011; Hoffimann et al., 2017; Vidal et al., 2021a). The phenomenon of “green gentrification” (Curran and Hamilton, 2018) is a further problem which urges for the consideration of environmental injustice enforced by non-equity-oriented policies for urban greening. This, for instance, becomes evident in situations where wealthier migrants experience more benefits compared to those who are socially disadvantaged. Given such shortfalls, the main challenge is to enforce a collective effort to look beyond the greenness, previously addressed by articles integrated within this special issue.
- Environmental and health research methodologies: integrating a transdisciplinary approach in a higher education cross-cutting curricular unitPublication . Dinis, Maria Alzira Pimenta; Vidal, Diogo Guedes; Dias, RicardoIt is currently undeniable that human health is influenced by the environment and the lifestyle. The United Nations Agenda 2030 emphasizes that the assessment of sustainability cannot dissociate ecological and social problems, specifically concerning health, the environment and human beings, in a logic of collaborative platforms for sharing knowledge, solutions and good practices. These shared approaches should integrate a higher education curriculum, namely through the inclusion of a curricular unit that could be part of all courses and scientific fields to promote the interdisciplinary necessary to deal with wicked problems, such as those involved in environment and health. Sustainability cannot rely on incorporating concepts and methodologies beyond each cut (multidisciplinary). Instead, it must result from a dialogue between such concepts and methodologies (interdisciplinary), making it possible to overcome these cuts (transdisciplinary). This is the way through which scientific community deal with cross-cutting issues, accelerating progress when strengthening the robust methodological approaches of the research to be carried out. This work aims to emphasize the importance of the careful choice of methodologies to be applied to the environment and health fields. A new curricular unit called “Environmental and Health Research Methodologies” to achieve transdisciplinary among different knowledge areas is proposed, contributing to a vision of indivisibility of sustainability science and methods.
- A Escala de Identidade Ambientalista (EIA): estrutura fatorial e propriedades psicométricasPublication . Vidal, Diogo Guedes; Dias, Ricardo; Seixas, Paulo CastroA Escala de Identidade Ambientalista (EIA) é uma ferramenta desenvolvida para identificar e refletir sobre perfis identitários ambientalistas. O objetivo deste trabalho é o de identificar a sua estrutura factorial e o de testar as suas propriedades psicométricas, incluindo a consistência interna e validade do construto. A amostra inclui 110 participantes residentes em Portugal continental. Foram aplicadas técnicas de análise factorial exploratória para identificar a estrutura factorial da escala. A consistência interna da escala foi avaliada através do Alfa de Cronbach. A análise fatorial de componentes principais com rotação de varimax suporta um modelo com 2 fatores que explicam 62,4 % da variância total. As 2 subescalas (Valores e Práticas) demonstram consistências internas aceitáveis (coeficiente de alfa: 0.71 e 0.73 respetivamente), bem como a EIA total (coeficiente de alfa: 0.74). A validade do construto é, assim, suportada pela capacidade da EIA em identificar diferentes perfis ambientalistas. Conclui-se que a EIA apresenta propriedades psicométricas aceitáveis e que a sua aplicação é pertinente na identificação de perfis ambientalistas. No entanto, são necessários estudos futuros com uma amostra de maior dimensão que permita validar a EIA de forma mais robusta, nomeadamente através da estabilidade temporal e validade descriminante.
- Escala de identidade ambientalista: uma ferramenta para descobrirmos que ambientalistas somosPublication . Seixas, Paulo Castro; Dias, Ricardo; Vidal, Diogo GuedesO artigo propõe uma Escala que possibilita a discussão reflexiva de perfis identitários ambientalistas. O ambientalismo é um elemento identitário central do século XXI e, no entanto, a literatura falha em tipologias ambientalistas que permitam reflexão e posicionamentos. A metodologia seguida implicou uma análise histórica do ambientalismo. Tal análise deu lugar a 8 subescalas que se agregam num único instrumento metodológico: a Escala de Identidade Ambientalista (EIA). O contributo principal é um instrumento simples que possibilita uma aproximação reflexiva de cada sujeito a um conjunto de tipos ideais de identidades ambientalistas, sustentando metodologias ativas de intervenção.
- Os espaços verdes e as preocupações com a sustentabilidade nos Planos Diretores Municipais de 3ª geração: análise comparativa das Áreas Metropolitanas em PortugalPublication . Dias, Ricardo; Vidal, Diogo Guedes; Castro Seixas, Paulo; Maia, Rui LeandroEste texto analisa o papel atribuído aos espaços verdes urbanos na reformulação dos Planos Diretores Municipais (PDMs) que decorreu até Julho de 2020 em Portugal. Tendo em conta os serviços de ecossistemas destes espaços para a sustentabilidade nas cidades, questionou-se até que ponto os municípios portugueses aproveitaram esta reformulação para potencializar tais contributos. Metodologicamente, a pesquisa centrou-se em dois estudos de caso, comparando as duas Áreas Metropolitanas (AMs) portuguesas, através de uma análise aos documentos revistos dos PDMs dos municípios que as constituem. O artigo conclui que o valor socioecológico dos espaços verdes é ainda amplamente negligenciado, bem como o planeamento urbano sustentável ao nível das AMs.
- Estudo comparativo do ultrassom terapêutico e da tecarterapia no tratamento dos sinais e sintomas da disfunção temporomandibularPublication . Dias, Ricardo; Cervaens, Mariana; Andrade, JoanaA disfunção temporomandibular (DTM) está correlacionada com problemas surgindo da articulação assim como, com mudanças musculares e ligamentares envolventes. Objetivo: Realizar um estudo comparativo entre o uso de ultrassom e tecarterapia (TECAR) nos sinais e sintomas de uma DTM. Metodologia: A amostra foi constituída por 30 estudantes de Fisioterapia da Escola Superior de Saúde Fernando Pessoa entre os 20 e os 30 anos (22,00 ± 2 anos), aos quais foi aplicado o Índice de Helkimo (IH), Índice de Mobilidade Mandibular (IMM), a avaliação do limiar de dor através do uso do algómetro e a avaliação subjetiva da dor através da escala numérica da dor (END). Foram aleatoriamente divididos em três grupos, um submetido ao tratamento com ultrassom terapêutico, outro com TECAR e um último, de controlo, que não realizou qualquer intervenção. Resultados: Ambos os grupos de tratamento apresentaram melhorias significativas em todos os parâmetros avaliativos, ocorrendo uma diminuição da dor, um aumento do limiar de dor, assim como uma melhoria do IMM e IH, no entanto, no grupo controlo não se verificou qualquer alteração avaliativa. Conclusão: Os métodos terapêuticos ultrassom ou TECAR foram igualmente eficazes na redução dos sinais e sintomas da DTM, não havendo diferenças significativas entre eles.

- Measuring environmental concern of Urban Green Spaces’ Users (UGSU) through the application of the New Ecological Paradigm Scale (NEPS): evidence from a southern european cityPublication . Vidal, Diogo Guedes; Dias, Ricardo; Seixas, Paulo Castro; Dinis, Maria Alzira Pimenta; Fernandes, Cláudia; Barros, Nelson; Maia, Rui LeandroThe New Ecological Paradigm scale (NEPS) is a worldwide survey-based metric, designed to measure the environmental concern of groups of people through a single instrument including fifteen statements. As far as it is known, the NEPS has never been previously applied to Urban Green Spaces’ Users (UGSU). The assessment and analysis of this group’s perception of the environmental concern could be a core element in promoting environmental sustainability. This research aims to measure and analyse UGSU (n = 132) NEPS score in a southern European city. The factor structure and psychometric properties of the NEPS revealed good internal consistency and the explained variance is higher than the original study. Thus, its application is considered reliable when applied to UGSU. UGSU presented higher ecocentric values when compared to the general population, university teachers and agricultural farmers. Concerning UGSU sociodemographic characteristics, the youngers adults are those that mostly share an ecological worldview. Also, those that more often visit Urban Green Spaces (UGS), recognized that plants and animals have the same right to exist as humans. It is expected that this work may contribute to explore the usefulness of the NEPS application in different contexts and to underline values that will have a significant effect on debates involving environmental sustainability as a cross-cutting issue.
