Accessibility and availability of urban green areas within the 15-minute city scope: Lisbon case study
| Resumo: | The 15-minute city concept has gain traction in recent years around the world, promoting well connected and sustainable cities where essential amenities are accessible within a 15-minute walk or bicycle ride, fostering the well-being and quality of life of urban residents. In a post-pandemic era, citizens of densely populated cities became aware of the vulnerability and poorer health outcomes of being restricted to confined spaces and controlled mobility, giving more relevance to the proximity to urban green spaces, as these not only represent an escape for the daily stress, but also bring substantial benefits to the mental and physical health of citizens. As urban green spaces are considered essential amenities within the 15-minute city approach, this new way of reorganizing the urban accessibility system advocates the proximity of these spaces to the homes of urban residents. The present study seeks to measure the availability and accessibility of urban green spaces in the light of the 15-minute concept, in the city of Lisbon, Portugal. Furthermore, this study focuses on results per parish, aiming to represent an indicator for residents’ accessibility to green areas in the parishes of Lisbon, within the 15-minute scope. An ArcGIS network analysis technique was employed to summarize population from Census statistical polygons into 15-minute service areas generated around the green areas of the city, retrieved from an open data portal. The results aggregated by parish showcase that on a rather superficial level, Lisbon is overall well connected within the 15-minute scope in respect to distance between residents’ homes and nearest green spaces. All in all, most residents of Lisbon only need to walk 15 minutes at most to reach at least one urban green space from their place of residence. This work represents a source of awareness and further comprehension of the spatial distribution of green spaces in Lisbon for urban planners and designers, with the optimization of an accessible and sustainable urban city in sight. |
