As 2021 draws to an end, much of the world is slowly emerging towards post-pandemic life. Focus is shifting from response to recovery. Governments, activists and academics are arguing for a green recovery – a one-off opportunity to truly incorporate climate change objectives, sustainability and equity into future development.
Cities served as the frontline to the pandemic and will continue to do so in efforts to transition towards a sustainable recovery. Building the cities of the future was the focus of a recent NESTA webinar in conversation with Daisy Narayanan, Senior Manager of Placemaking and Mobility at the City of Edinburgh Council. It highlighted the importance of creating urban environments that put people first for healthy, safe and sustainable communities.
Opportunities for cities
Narayanan argued that positives can be taken from COVID-19, as it inspired collaboration across sectors and communities whilst proving the responsiveness and adaptability of traditional systems. She believes that this mindset should be harnessed going forward to facilitate meaningful changes and progression within our cities for everyone.
Describing herself as a ‘relentless optimist’, she stated, “I think there is something about this moment in time where there is a real kind of desire to move forward, in a way that changes how things used to be, into what things need to be or should be. I think there is a lot of excitement around shaping that together.”
Narayanan went on to talk about the opportunities she sees for transforming our public spaces with collaboration across planning, transport and economic development. She is excited by the potential of concepts such as the ‘20-minute neighbourhood’ and its growing presence within city planning around the world and in her own city of Edinburgh.
More broadly, she is excited that citizens are recognising the importance of living well locally and that community wellbeing should be inherent to placemaking.
The inequality of green space
Whilst positives can be drawn from collaboration during the pandemic, it also magnified how divisive our cities’ environmental issues can be. Pollution, congestion and dwindling green spaces compounded the health and social challenges for many of those living in urban areas.
With most inside amenities forced to close during periods of lockdown, city dwellers turned to parks for exercise and socialising in unprecedented numbers. However, urban green spaces proved to be unequal in distribution. Socioeconomic status is the most likely determinant to green space accessibility and quality, and access is typically limited to the more scenic neighbourhoods with higher average incomes.
The benefits of urban green spaces to an individual’s health and wellbeing are well documented, with associations between the presence of green spaces, greater quality of life and decreased risk of excess mortality. There is growing research suggesting that city populations without the provision of green spaces in the UK had typically higher instances of mental health issues, such as COVID-related anxiety and isolation.
Of course, the provision of green spaces is only one of a number of factors highlighted in discussions around equalities, health and well-being in urban areas. However, the pandemic exposed the barriers to accessing the potential value provided by such spaces which could continue to reinforce inequalities.
Can a green integrated approach to transforming our cities tackle inequality and promote wellness in the post-COVID city?
Lessons from Milan’s green placemaking
During the webinar, Narayanan briefly touched upon how Milan is a commendable example of a city making really big changes to its public spaces for the benefit of its citizens.
The city has impressive commitments for using nature-based solutions to increase resilience towards future environmental and health crises, whilst stimulating an equity-based approach to tackling climate change.
The Mayor of Milan, Giuseppe Sala, committed his city to green urbanism before the pandemic and has since campaigned for efforts to be increased due to the unequal challenges created in cities.
He stated, “The green and just recovery that is needed to create more sustainable and healthier cities sees urban nature as a key element for building back better… I have been clear that any recovery in my city, in Italy and for Europe, must be rooted in these principles of equity and climate action.”
Sala aims to plant three million trees across Milan by 2030 to tackle climate change and to halt the trend of deteriorating air quality. At the core of this strategy is the transformation of derelict land in deprived neighbourhoods into 20 high quality urban parks.
The city government is providing for residents to have trees planted in their private gardens and upon flat rooftops, whilst greenery is being incorporated into car parks and on the sides of office blocks.
Integrating green spaces, food supply and equity, the city’s growing number of community gardens and allotments are often situated upon apartment block rooftops. Residents can grow and collect food whilst local restaurants are encouraged to use ingredients from the nearby streets. Locals have also lauded the social spaces that these gardens have become, as users can collaborate and educate each other through gardening.
Perhaps the most symbolic project in Milan’s transition is the Bosco Verticale or ‘Vertical Forest’- two residential apartment blocks which have been almost completely covered with trees, perennials and shrubbery. Designed by architect Stefano Boeri, the 80m and 112m high buildings have the equivalent vegetation of 30,000 square metres worth of woodland upon only 3,000 square metres of concrete.
Consisting of hundreds of plant species of various shapes and colours, the project is a popular, living landmark throughout the year. Not only an appealing addition to the Milan skyline, the urban vegetation has been a remarkable success – lowering temperatures, encouraging 20 new bird species into the area and absorbing 30 metric tonnes of carbon dioxide from the atmosphere each year.
The towers demonstrate the multiple benefits that can be achieved from small-scale integrated approaches to increasing green spaces. The concept is already being replicated in cities around the world.
If successful, it is believed that Milan’s vast increase in vegetation has the potential to absorb an additional five million tonnes of carbon dioxide each year, whilst significantly decreasing the presence of pollutant particles in the air associated with cancer and respiratory diseases.
Milan’s transformation is exemplary of a city that is learning from previous vulnerabilities, using urban space to directly promote citizen wellbeing whilst tackling climate change.
As Narayanan argues, all cities now have the opportunity to put people’s needs and wellbeing at the centre of future urban spaces. Whilst citizens and authorities often both want to achieve attractive, sustainable and healthy places, she argues that citizen voices get lost in consultation.
As a step to progressing away from this, she says: “Consultations should be more like conversations. Discussions need to be done respectfully, evidence-based, data-based and using people’s stories and life as the basis for change.”
