Open Public Spaces

CONTEXT

© foto select / Shutterstock.com

The presence of open public spaces that favour the growth of cities’ green coverage and urban interaction with blue spaces like lakes, rivers and fountains is essential to reduce the effects of heat islands by increasing shade and reducing heat absorption. The heat island effect is expected to get worse as a consequence of the temperature increases associated with climate change. At the same time, a suitable public space can improve air quality and act as a climate shelter.

Additionally, living close to open public spaces is closely linked to numerous benefits for the health of the population. People who perceive their neighbourhoods to be attractive, with the presence of green or blue zones, are more likely to carry out physical activities in the open air in their free time or to travel (by bicycle or on foot), regardless of age. However, the suitability and type of public spaces should be taken into account to encourage their use and increase safety (lighting, drainage and condition of the paving).

Moreover, the aesthetics of the environment, such as the ability to see or interact with natural areas (green spaces, rivers, lakes…), influence the levels of overweight and obesity of the population and general health levels, but more specifically mental health, emotional wellbeing, vitality, anguish, stress, cognitive function, social connections and happiness.

 

OBJECTIVE

  • Increase green cover and the integration of natural spaces in cities for the health and quality of life of the population.

PROPOSALS AND RECOMMENDATIONS

Parks, free spaces and leisure spaces 

  • Integrate the planning of green and blue spaces, prioritise the least advantaged areas and the development of an attractive and accessible design.
  • Prioritise improvements to green and blue spaces of infrastructure that supports physical activity, especially where there are paths to walk, bicycle lanes and water activities.
  • Provide open spaces to support physical activity in all neighbourhoods.
  • Adapt and promote emblematic parks and green spaces to favour a healthy and sustainable lifestyle, fostering opportunities for leisure and relaxation. Prioritise parks and green areas that are easy to access, safe and connected to housing and transport hubs.
  • Remove the borders of traditional parks (fences that delimit the parks), defining an absolute transition between the urban space and the green space.
  • Incentivise the creation of community green spaces in the neighbourhoods (balconies, plants on ground level, horticultural areas, gardens, etc.). Provide advice on the design of these spaces so they are good quality and, if possible, accessible. Prioritise their location in areas adjacent to housing, offices and schools.
  • Create or improve urban forests.
  • Prioritise access to nature at a distance of less than five minutes from housing on foot.
  • Plan a network of multifunctional open spaces in all communities to support physical activity, leisure and uses of the countryside.
  • Include green areas for sport and for multiple uses (play, rest, activities, walking, cycling, etc.).
  • Adopt a green-building design in new public building projects and prioritise these improvements in public rental housing.
  • Plan improvements to green infrastructure where there are public transport stops. • Create new routes to walk and cycle in the urban fabric.
  • Incorporate cool pavements and “breeze paths” to create green routes, strolling routes, and hiking and cycling trails.
  • Develop a green ring in the city to expand the possibilities to enjoy the city and its surrounding area through leisure activities and sport. Consider the opportunities of these areas to recover biodiversity, restore ecological and countryside areas, connect recreational zones, create routes for walking, cycling and running, recover deteriorated areas, etc.


Aesthetics 

  • Implement improvements to the urban green space on different scales.
  • Implement a wide diversity of local plant species that contain some rare species, if possible, with many indigenous trees, shrubs, fruit bushes, fruit trees and wild flowers. Select the species in accordance with the needs of the spaces, taking into consideration the year-round climate and climate change.
  • Plant plants on paths and corridors, open spaces, gardens, motorway hard shoulders and roundabouts and close to buildings.


Green cover and plant life 

  • Expand the green cover of urban areas that have relatively low levels of plant life.
  • Increase the planting of trees in the connecting areas of the public space, parks and vulnerable areas close to the community and route locations.
  • Increase the extension of green roofs in the urban environment, especially in the city centre and in neighbourhoods with a high population density. Install green roofs on all new buildings with a gradient of less than 30 degrees and on different types of buildings (bicycle parking facilities, schools, warehouses, public buildings, upper walkways of underground garages, etc.).
  • Install green facades on buildings in the city centre as if there were a park. Plant local species of robust plants that require relatively low maintenance on them.
  • Use abandoned areas of the urban landscape to expand the green cover.

  • Bristol. Disposa del Bristol Green Infraestructure Diagram. Tenen mapat totes les àrees verdes, així com la seva interconnexió entre la ciutat i l’entorn més proper.
    Tenen els Strategic Green Infrastructure Links, així com el Green Belt Area que també està connectat amb la ciutat. El concepte d’infraestructura verda té un paper essencial en la planificació de l’espai. Contemplen com a corredors verds els camins, els camins per a bicicletes i també els rierols (watercourses). Tots aquests corredors connecten els espais verds de la ciutat i serveixen com a enllaços per al moviment de la fauna i de la gent. Un dels trams més destacats d’aquesta infraestructura és la que connecta, des del centre de cadascuna de les ciutats, Bath i Bristol, i que al llarg de la ruta proveeix diferents zones d’oci i recreació als usuaris i també zones de refugi de la fauna salvatge de la zona. 
  • Viena. Sistemàticament des de 1991 fotografien (bio-monitoritzen) des de l’aire la ciutat per determinar la ‘quantitat de verd’ que té la ciutat, i determinar els canvis que s’hi produeixen. Algunes de les mesures per reforçar els espais verds, i al mateix temps lluitar contra el canvi climàtic i crear illes contra la calor, desenvolupades a la ciutat són: instal·lar vegetació al costat de les carreteres i carrers, als espais verds i a les illes interiors i frontals dels edificis; enllaçar els espais verds de la ciutat, permetre el creixement espontani de la vegetació en àrees amb poc o gens d’ús, generar noves àrees d’arbres plantant-ne de nous, conservar i incrementar el nombre d’arbres, seleccionar les espècies adequades que millor s’adaptin al canvi climàtic. També procuren augmentar la presència d’ombra a la ciutat: augmentar l’ombra als espais oberts propers als edificis, als espais oberts allunyats dels edificis (parcs i espais de lleure i esport), i ombrejar els espais oberts dels carrers.

    Viena disposa d’un cinturó verd, creat el 1905, que està compost per boscos i camps. El cinturó abasta un 30% de la totalitat de l’àrea urbana. Viena també compta amb uns 2000 parcs de tipologia molt diversa, que inclouen 45 grans àrees recreatives. Tanmateix, la creació i el disseny de nous espais verds continua sent un dels principals components de les polítiques ambientals de la ciutat. I en aquest sentit han fet i fan noves mesures per ampliar l’abast de l’àrea verda:

    • El Rundumadum Trail. És un camí de 120 quilòmetres de llargada que enllaça cinc paisatges diferents (el paisatge de Viena és inusualment variat: la ciutat està situada en una intersecció de diferents tipus de climes) i que es relaciona amb el cinturó verd de la ciutat.
    • El nou carril bici al llarg del riu Mauerbach fins als afores de la ciutat.
    • Viena també ha dissenyat falques verdes (green wedges) per relligar les grans àrees verdes de la ciutat i el cinturó verd amb les zones més densament poblades.
    • A les zones amb molta densitat de població i edificis alts hi han situat nous parcs i àrees verdes.
    • Procuren mantenir i crear àrees de natura urbana salvatge. (urban wilderness) tenint en compte les característiques biotòpiques, plantant nous arbres, instal·lant nius d’ocells, deixant els arbres morts...
    • Les àrees que formen el cinturó verd tenen una consideració especial i estan especialment protegides.
    • La ciutat ha comprat importants extensions de terreny en diferents emplaçaments per garantir que esdevinguessin àrees verdes i parcs per la ciutat.
    • La preservació i la creació d’espais verds d’alta qualitat és una de les prioritats de la ciutat. I al mateix temps, també ho és que aquests espais puguin ser emprats per fer-hi usos recreatius, de lleure i que siguin espais que protegeixin la biodiversitat.
