1 in 4 Australians is lonely. Quality green spaces in our cities offer a solution

Higher-quality green space maximises opportunities for both social connection and health

Australian adults feel lonely, and the impacts can be dire. Loneliness increases our risks of , , , and . But and miss the point: we鈥檝e been building for loneliness over many decades and decision-makers have been asleep at the wheel.

Having studied the issue, we view loneliness as largely a product of our environment 鈥� what we call a 鈥渓onelygenic environment鈥� 鈥� not a disease or a problem with any particular individual. So what is this 鈥渓onelygenic environment鈥�?

Over decades, our cities have become sprawling low-density agglomerations. Many places are too far to walk from home. Short errands are routinely done by car, erasing opportunities to stop and chat with locals.

Large-scale felling of street trees has not only obliterated natural shade, but severed our connection with the 鈥渕ore than human鈥� world. Car traffic dominates residential roads, which are also clogged with parked cars.

We have lost the people-friendly streets that we once used for regularly gathering, playing and celebrating with neighbours. No wonder we now .

If the determinants of loneliness are largely environmental, so too must be the solutions. Yet we hear so little about this.

How much difference can green space make?

In a previous , we suggested investing in public green space is part of the solution to the epidemic of loneliness. The article was based on our that reported a greening target of 30% local landcover could cut the odds of becoming lonely by a quarter. Among people living alone, who tend to be more vulnerable to loneliness, green space cut those odds by up to a half.

But how can green space reduce loneliness? That鈥檚 the focus of our new of studies from around the world. Two-thirds of the studies found green space potentially protected people against loneliness.

Our review identified multiple pathways for reducing loneliness. These included:

1. building capacities for connection with community
2. restoring our sense of belonging and connection with nature
3. reducing harms, such as , that may otherwise lead to loneliness.

The quality of the green space matters

During the COVID-19 pandemic we undertook a nationally representative and found the odds of connecting with neighbours were five times higher for people who visited high-quality green space than for those who didn鈥檛 or couldn鈥檛.

Related benefits were also much stronger if green spaces were higher quality. For example, exercise and relief from stress were both more commonly reported by people visiting higher-quality green spaces.

Quality was defined by participants鈥� views on things such as access, aesthetics, facilities, incivilities (e.g. litter, disrepair) and safety. Perceptions are important because the qualities of a green space need to resonate for people to visit them.

Regular visits to green spaces foster attachment and belonging. These spaces permit quiet contemplation in solitude, but also bring people together and connect people with nature. They become revered as settings for gatherings, bonding, cheering and shared memory-making.

By encouraging relaxation and playfulness 鈥� which can be frowned upon in other settings 鈥� green spaces may also enable connection for people who otherwise find it difficult, such as those with highly introverted .

The psychologically restorative benefits of green space are now . Green spaces such as can serve as therapeutic landscapes, offering refuge and respite for those experiencing loneliness, which can stem from some form of trauma. While usually provided for patients, these settings might also offer sanctuaries for health professionals experiencing .

The bottom line is that higher-quality green space maximises opportunities for both social connection and health. While our previous and other studies highlight inequities in access to green space, we must pay even more attention to inequities in the quality of green space.

Consult communities to get it right

This may all sound like we think the impacts of green space are universally positive; we don鈥檛. For instance, many studies in countries such as , and report that some people with disabilities, who are already vulnerable to loneliness, face significant barriers to visiting green spaces and may feel 鈥渙ut of place鈥� within them.

Other research indicates that the creation or regeneration of green spaces in communities may be associated with , by making nearby housing less affordable.

In other words, a nearby green space that is highly attractive and a source of joy for some people may for others be a symbol of processes that aggravate loneliness and perpetuate misery.

That is why community views on the design of green space really matter. Consultation is key to ensure everyone feels meaningfully engaged in the process.

Our , and our new in particular, shows green space qualities depend on the context, preferences and needs of local residents. It is clear we need local networks of green spaces that provide something of value for everyone.

Finally, the process of urban greening itself can help counter loneliness by empowering communities to actively participate in creating and maintaining local green spaces. This has been done successfully over decades by the Royal Botanic Garden Sydney鈥檚 . By bringing people together to create green spaces, the garden has been quietly showing us the solution to our lonelygenic environment all along.
