Implementation of Healthy Corridors in Porto

: The project combines the perspectives of environmental, urban and social cohesion based on Nature Based Solutions (NbS) in order to improve the quality of life of the local population. The intention is to connect the eastern part of the city with the center by walking routes, small gardens, vegetable gardens, or other green solutions, make life easier for residents and attract tourists and visitors. Given the intention to implement new healthy corridors, the study area includes the most important strategic green areas (Parque Oriental, Praça da Corujeira, Quinta da Bonjóia, the municipality of Horto), services (schools, industry, health centers, local associations), as well as future projects, will soon take place in Campanhã (extension of Parque Oriental, Novo Matadouro, Monte da Bela). The Healthy Corridor design should formulate as many existing strategic areas as possible to be inclusive, reach more users and eliminate local fragmentation and disconnection. Actions are focused on implementing healthy corridors for the neighborhood of Campanhã through innovative and inclusive urban renewal, starting with joint construction and joint implementation of NbS with the participation of the local community.

Increased infiltration, water retention and flood protection
Improved air quality
Yes, urban trees help to improve air quality by facilitating widespread deposition of various gases and particles through the provision of large surface areas as well as through their influence on microclimate and air turbulence (Grote et al; 2016).
Reduced drought risk, cooling effect, urban heat island mitigation
Yes, urban green infrastructure such as street trees and urban parks have a significant role in mitigating urban heat and enhancing human comfort (Saaroni et al; 2018).
Biodiversity conservation or increased biodiversity
Yes, through the increase of green areas, the potential for biodiversity is also increased (Threlfall et al; 2017).
Ecosystem restoration and/or improved ecological connectivity
Yes, implementing new healthy corridors, including the most relevant strategic green spaces, in order to be inclusive, reach more users, suppress local fragmentation and improveecological connectivity.
Increased quality and quantity of green and blue infrastructures
Yes, expanding green infrastructure by increasing green areas between neighborhoods.
Sustainable urbanisation
Yes, the implementation of health corridors is intended to make the city more sustainable through the provision of cleaner air and reduction of ambient temperatures and soil erosion.
Increased access to green infrastructure
Yes, this action also aims to increase access to green infrastructure, highlighting the benefits that an ecological corridor can bring to the population.
Increased social interaction and inclusion
Yes, the project aims to involve local citizens in groups of volunteers to create together Healthy Corridors for the neighbourhood of Campanhã (URBiNAT, s.a.).
Increased willingness, participation, investment in NBS
Yes, the Health Corridors co-creation process will be organized in 4 phases, joint diagnostics, joint project, joint implementation and joint control, where citizens are invited to participate in various activities (URBiNAT, s.a.).
Provision of health benefits
Yes, the importance of trees in urban areas has been associated with the provision of valuable environmental services to combat challenges such as pollution, urban heat, and flooding, as well as to improve social cohesion, human health, and well‐being (Cavender, Donnelly, 2019). Urban green interventions play an important role in creating a culture of health and wellbeing (Hunter at al; 2019).
Education, knowledge exchange and learning
Yes, citizens are invited to participate in the project's workshops and public events in the form of educational trips with various interactive activities enhancing their experience and knowledge (URBiNAT, s.a.).
Drought and heat risk
Yes, the Mediterranean Basin is undergoing a warming trend with longer and warmer summers, an increase in the frequency and the severity of heatwaves, changes in precipitation patterns and a reduction in rainfall amounts (Linares et al; 2020).
Loss of biodiversity
Low availability of green infrastructure
Low aesthetic value
Lack of local sense of ownership, participation
Limited knowledge about biodiversity
Good health and well-being (SDG3)
Sustainable cities and communities (SDG11)
Climate action, resilience, mitigation and adaptation (SDG13)
Terrestrial biodiversity (SDG15)
Yes, this action aims to increase tree cover.
