- Emerging patterns of human behavior in urban green spaces: the potential of behavioral mapping towards responsive human-nature relationsPublication . Vidal, Diogo Guedes; Vilaça, Helena; Barros, Nelson; Maia, Rui LeandroPublic Urban Green Spaces (PUGS) play a vital role in the dense urban fabric as places of people-nature contact but also as socialization spots. Despite some advances in the field, the relationship between the PUGS surroundings and their users’ behaviours remains unclear. Therefore, this study examined the patterns of human behaviour in four PUGS of the city of Porto, on the north Portuguese coast.
- Green spaces and Human Rights: to an environmental justice in urban space: espaços verdes e Direitos Humanos: para uma justiça ambiental em espaço urbanoPublication . Vidal, Diogo Guedes; Maia, Rui Leandro; Vilaça, Helena; Barros, Nelson; Oliveira, GiselaCities must be pleasant and healthy spaces able to contribute to ecosystems regeneration and to bring closer Humans and Nature. Increase urbanization carries socioenvironmental challenges that may be tackled by promoting green spaces as safeguarders of sustainability and of the connection between users and the biosphere. Cities are unequal spaces regarding the distribution of available resources and infrastructures (Bourdieu 1993, Maia 2003, Tilly, 2005, Therborn, 2006, Massey, 2007, Costa, 2012). The 11th goal of the 2030 Agenda for Sustainable Development states that societies must ensure universal access to safe, inclusive and fully accessible public spaces. The production and reproduction of space is a competition process for the physical and symbolic space which results in the creation of socio-economic clusters within the cities, with cities emerging within the city. The fair distribution of urban green spaces must be ensured in both quantity and quality in terms of ecological, social or health promotion services. The concept of Environmental Justice assumes that all individuals, regardless of their social, cultural or economic condition, should have the right to a fair treatment and to get involved in the development, implementation and enforcement of environmental regulations and policies (Lawson, 2008). This communication aims to reflect on the distribution and quality of green spaces in the city of Porto and on how their presence may contribute to environmental justice. The city of Porto does not offer an equitable distribution of green spaces that takes into account its population mosaic. In areas of greater socio-economic deprivation and vulnerable to environmental problems, it is observable that the quantity and quality of green areas is much lower when compared to other socially and economically favoured areas of the city.
- How gardens and public parks are responding to cities social and environmental challenges? a case study of Porto, PortugalPublication . Vidal, Diogo Guedes; Fernandes, Cláudia; Barros, Nelson; Vilaça, Helena; Maia, Rui LeandroCities must be pleasant and healthy spaces able to contribute to ecosystems regeneration and bring closer Humans and Nature. According to the 11 SDG of 2030 Agenda, by 2030 should be provided universal access to safe and inclusive public green spaces. Scientific evidences emphasize the multiple benefits of ecosystems services: regulation, provision, cultural and support.The main goal of this research aims to evaluate how the ecosystems services of gardens and public parks (GPP), in the city Porto, are responding to contemporary social and ecological challenges and, consequently, which differences are found within city socioeconomic and environmental vulnerability clusters.
- Methodological proposal to evaluate public urban green spacesPublication . Vidal, Diogo Guedes; Fernandes, Cláudia; Barros, Nelson; Maia, Rui LeandroCities must be pleasant and healthy spaces able to contribute to ecosystems regeneration and to bring closer Humans and Nature. However, cities are unequal spaces regarding the distribution of environmental resources, resulting in environmental injustice: socioeconomic vulnerable areas are, simultaneously, those where is identified the bigger environmental vulnerability, in part due to the poor quality of public green spaces - resulting in poor air quality and the increase of noise level – and the social segregation. Therefore, the present work aim to present a methodological proposal to evaluate urban green spaces quality.
- Qualificar para melhor intervir: identificação de tipologias de espaços verdes urbanos com base no potencial de serviços de ecossistemaPublication . Vidal, Diogo Guedes; Dias, Ricardo; Patoilo Teixeira, Catarina; Fernandes, Cláudia; Barros, Nelson; Maia, Rui LeandroOs espaços verdes urbanos (EVU) contribuem para a qualidade do ambiente nas cidades, sendo reconhecidos como uma das soluções baseadas na natureza mais eficazes na promoção da resiliência local. Além da importância ambiental são também grandes promotores de estilos de vida saudáveis contribuindo para a saúde e bem-estar dos seus utilizadores. Os líderes municipais são responsáveis pela gestão e manutenção de muitos EVU, mas as evidências atuais identificam um conhecimento limitado sobre a governança da infraestrutura verde urbana, sendo a falta de dados identificada como uma das principais restrições a uma intervenção eficiente. Perante esta lacuna, este estudo teve como objetivo identificar aglomerados de EVU tendo por base a aplicação in situ de uma grelha de avaliação do potencial de serviços de ecossistema (PSE), através de um estudo de caso de 25 EVU da cidade de Porto. Os resultados das análises estatísticas multivariadas permitem identificar como dimensões preditoras do PSE a qualidade ambiental e comodidades. Para além disso, foram validados cinco aglomerados de EVU: i) ambientalmente capacitados e socialmente expectantes, ii) socioambientalmente capacitados, iii) ambientalmente capacitados mas socialmente adinâmicos, iv) socioambientalmente incapacitados e v) socioambientalmente inexplorados. Estas evidências são úteis no desenho de intervenções mais adequadas às características dos EVU, contribuindo para o aumento do PSE e da qualidade do ambiente urbano.
- The potential of urban green spaces to face contemporary socioenvironmental challengesPublication . Vidal, Diogo Guedes; Maia, Rui Leandro; Barros, Nelson; Vilaça, HelenaCities and urban spaces are, in our days, places of the most diversified dynamics. Since the beginning of the XX century, urbanization, demographic explosion (Kondo et al., 2018; UN, 2014) and consumer behaviour have affect environment and, consequently, human health. The connection between environment and human health is undeniable and as well as the impacts of environmental pollution, namely air pollution, on the population’s health (Raaschou-Nielsen et al., 2016; Pope et al., 2002). Towards this evidence, it is an urgent need that cities adopt strategies in order to face these contemporary social and environmental problems. Several studies had focused on the potentials of Urban Green Spaces (UGS), aiming to prove their capability to mitigate air pollution, rejuvenate urban areas, control stress and mental health, minimize ischemic diseases and empower social participation (Seymour, 2016; James et al., 2015; Haluza et al., 2014; Bowler, et al., 2010).
- The right to access urban green spaces: an (in)equality issue in the contemporary societiesPublication . Vidal, Diogo Guedes; Maia, Rui; Barros, Nelson; Vilaça, HelenaWorld's population living in cities is expected to rise from around 54% to around 66% by 2050 (Maia, 2014, UN, 2014). Urban green spaces (UGS) could be assumed as a link between nature and urban life. Far from being only understood as passives spaces of leisure and socialization, UGS are endowed with unequivocal potentialities in the promotion of a more inclusive and participative society. Many studies had focused on this aspect, sometimes neglecting the beneficial side that directly or indirectly contributes to the improvement of life quality of individuals. In this way, UGS have the power to rejuvenate urban network and surrounding residential quality, improving human health (WHO, 2016; Kuo, 2015; Sturm & Cohen, 2014; Lee &Maheswaran, 2010), mitigate air pollution and noise (WHO, 2017) and minimizing the impacts caused by climate change (WHO, 2017; Kabischet al., 2016; Mathey et al., 2011). This communication intends to share some preliminary reflections about a research with the main goal to understand if the cities are responding to population needs related to social and environmental challenges, taking into account the role of UGS in the city of Porto. Access to UGS should be understood as a universal right, as way of practicing citizenship. For this reason, it is important to analyse if exists or not equal access to this spaces, being a reflex of how society is organised. The importance of this reflection is aligned with the 11th goal of the 2030 agenda for sustainable development with the target by 2030 to provide universal access to safe, inclusive and accessible, green and public spaces, in particular for women, children, older persons and persons with disabilities(UN, 2015). An equal access to UGS as a right could improve social interaction and community cohesiveness, as well as contribute to a more sustainable society.
