- Usos e perceções sobre jardins e parques públicos urbanos - resultados preliminares de um inquérito na cidade do Porto (Portugal)Publication . Vidal, Diogo Guedes; Fernandes, Cláudia; Viterbo, Lilian Monteiro Ferrari; Vilaça, Helena; Barros, Nelson; Maia, Rui LeandroA crescente concentração populacional nas cidades é reconhecida como um dos principais desafios contemporâneos. É nas cidades que os desafios sociais e ambientais se agigantam, implicando um olhar sobre o planeamento urbano sustentável. Os espaços verdes urbanos desempenham um papel importante na resposta a tais desafios, concretamente através dos serviços dos ecossistemas. Os serviços culturais ganham especial relevo, nomeadamente na melhoria da saúde mental, física e social dos seus utilizadores. Este trabalho tem como objetivos conhecer os usos e as perceções dos utilizadores dos jardins e parques públicos da cidade do Porto, bem como de que forma esses mesmos espaços estão a satisfazer as suas necessidades, estabelecendo uma relação com a localização dos mesmos na cidade tendo em conta uma maior ou menor privação socioeconómica e ambiental. Partindo de inquérito por questionário em fase de aplicação aos utilizadores de 25 jardins e parques de acesso público, propõem-se uma discussão sobre os resultados preliminares obtidos (n=131). Os resultados permitem um esboçar do perfil dos potenciais utilizadores destes espaços, além de revelarem que espaços da cidade em áreas de maior privação socioeconómica e ambiental são percecionados pelos seus utilizadores como espaços verdes com menor qualidade. Espera-se que os resultados auxiliem na definição de estratégias de atratividade dos espaços verdes da cidade que possuem menor qualidade e se inserem em zonas de maior privação.
- Combining an evaluation grid application to assess ecosystem services of urban green spaces and a socioeconomic spatial analysisPublication . Vidal, Diogo Guedes; Fernandes, Cláudia; Viterbo, Lilian Monteiro Ferrari; Vilaça, Helena; Barros, Nelson; Maia, Rui LeandroThe complex interaction of ecological and social systems has shaped the cities through the time. This fosters the need to develop interdisciplinary approaches to urban issues by combining natural and social sciences. Cities, as the predominant mode of social organization, are vulnerable to social and environmental challenges which urban green spaces (UGS) can contribute to solve by the ecosystem services (ES) that can provide. The objective was to assess the quality of UGS framed by the ES classification and relate with the provision of these services in areas of distinct socioeconomic and environmental deprivation. An evaluation grid was applied in 25 UGS in the city of Porto. Socioeconomic and environmental deprivation index applied by the Porto City Hall in the Municipal Master plan to divide the city into 5 clusters of deprivation was used to select 5 UGS of each cluster. In the most deprived communities, namely in clusters of high and very high socioeconomic and environmental deprivation, the quality of UGS is lower than in the less vulnerable ones. Besides this, it was found that some UGS located in clusters with higher vulnerability have an overall good quality, namely those located in historic and touristic areas of the city. The evaluation grid may be useful to the local authorities to diagnose, monitor and evaluate the ES of UGS and to identify situations of environmental injustice contributing to pursue the implementation of sustainable development goals at a local level.
- Development and validation of a grid to evaluate ecosystem services of public urban green spaces in Porto (Portugal)Publication . Vidal, Diogo Guedes; Fernandes, Cláudia; Viterbo, Lilian Monteiro Ferrari; Vilaça, Helena; Barros, Nelson; Maia, Rui LeandroCities must be pleasant and healthy spaces able to contribute to ecosystems regeneration and to bring closer Humans and Nature. Contemporary social and environmental issues present big challenges to promoting sustainable and resilient cities. The potential of ecosystem services of the urban green spaces is visible in the regeneration of urban environment, namely in the improvement of environmental and public health and social dimensions. This work presents the development and validation of a grid to evaluate ecosystem services of public urban green spaces. The grid was applied in 25 public urban green spaces in the city of Porto. Statistical tests were performed to evaluate the reliability and consistency of the tool. Results show that the grid is robust and reliable, thus its application is acceptable and could result in potential gains. These include the monitoring of ecosystem services of public urban green spaces to adjust them to citizen’s social and environmental needs, namely if the tool will be adopted by the municipal department of green spaces and infrastructure management of the city of Porto, Portugal.
