It\u2019s not just easy to miss, but often downright hard to notice. A simple patch of greenery in a city may seem like a blip in the concrete jungle, but it\u2019s an extremely powerful way to solve a bunch of problems at once: Studies have shown that green spaces improve urbanites\u2019 mental health<\/a>, make summers more bearable<\/a>, and prevent flooding by soaking up stormwater<\/a>.\u00a0<\/p>\n

When these plots are planned \u2014 as opposed to letting vacant lots grow wild, which is valuable in its own right<\/a> \u2014 they become extra powerful. You may have even enjoyed one without knowing it: the \u201cpocket garden.\u201d Tucked into spaces accessible to pedestrians, like sidewalks, hospital grounds, and campuses, they can be engineered to turn heat-absorbing concrete into air-cooling oases packed with vegetation and seating for people to escape the metropolitan bustle.\u00a0<\/p>\n

\u201cThis increasing prioritization of creating green spaces in unexpected spots and underutilized spaces in communities is not only going to be making our communities more resilient, it\u2019s going to be making people healthier,\u201d said Dan Lambe, chief executive of the nonprofit Arbor Day Foundation, which promotes urban forestry. \u201cA little bit of green goes a long way.\u201d<\/p>\n

Pocket gardens aren\u2019t gardens in the agriculturally productive sense, but ornamental grounds. (Though there\u2019s nothing stopping a designer from adding a fruit tree or two.) Ideally, they\u2019re host to native plant species, which bring several benefits. For one, they attract native pollinators like insects and birds, which get a source of food that powers them to go on and fertilize plants elsewhere, like crops in urban farms<\/a>. And two, if the vegetation is adapted to a particular region or condition, it\u2019s already used to the local climate \u2014 drought-tolerant varieties, for instance, won\u2019t require as much water to survive. Furthermore, choosing native grasses that don\u2019t need mowing can cut down on maintenance costs. And picking trees with big canopies will increase the amount of shade for people to use as refuge from the heat. (Sorry, palm trees, that means you\u2019re disqualified<\/a>.)<\/p>\n

Biodiversity \u2014 mixing tree species as opposed to planting 10 of the same kind \u2014 is key here. That attracts a broader range of pollinating animals, and builds resiliency into the system: If you only plant one variety of tree and a disease shows up, it can spread rapidly.<\/p>\n

And speaking of disease, trees have an additional superpower in their ability to scrub urban air of the pollutants that contribute to respiratory problems. In addition, the vegetation of a pocket park releases water vapor, bringing down air temperatures. This mitigates what\u2019s called the urban heat island effect, in which cities absorb the sun\u2019s energy all day and slowly release it into the night. Combined, reduced air pollution and temperatures improve public health.\u00a0<\/p>\n

There\u2019s also the harder-to-quantify bonus of people getting out of their cars and gathering in public spaces, no matter how diminutive. \u201cIt\u2019s actually a transition toward the pedestrian \u2014 toward the person \u2014 and away from the vehicle,\u201d said Eric Galipo, director of campus planning and urban design at the architecture firm FCA, which has integrated pocket gardens in their projects. (The photo at the top of this story is of one of the firm\u2019s projects, at Newark Beth Israel Medical Center.) \u201cWe may not spend as much time together as a society as we used to, and so these are great opportunities for that sort of connection to happen.\u201d<\/p>\n

When the rains come, these verdant plots take on another role as an infrastructural asset. As the planet heats up, rainfall increases because a warmer atmosphere can hold more moisture. In response, cities like Los Angeles and Pittsburgh are getting rid of concrete<\/a> to open up more green spaces<\/a>, which absorb rainfall, allowing it to seep underground. This reduces pressure on sewer systems that are struggling to handle increasingly heavy deluges. These systems, after all, were designed long ago for a different climate than we\u2019re dealing with today.\u00a0<\/p>\n

When a city prioritizes green spaces, you can actually hear the difference. Barcelona, for instance, has been developing superblocks<\/a>, which aim to improve city life by transforming car infrastructure into walkable spaces. That includes the development of \u201cgreen axes\u201d (the plural of \u201caxis,\u201d not the tool for chopping) full of vegetation and paths for strolling. A recent study<\/a> found that after these spaces were pedestrianized and vehicles disappeared, average noise levels fell by 3.1 decibels. (For context, hearing a car traveling at 65 mph from 25 feet away would be 77 decibels<\/a>.)<\/p>\n

While 3.1 may not seem like much, each increase of 10 decibels means a tenfold rise in loudness<\/a>. And we have to consider not just the decibels but how the kind of noise changed as Barcelona developed green axes: Revving engines, honking horns, and even the occasional cacophony of a car accident were replaced with voices. As the built environment dramatically changed, so too did the way that folks on foot experienced their surroundings. \u201cIf people see green in general, the noise perception tends to change,\u201d said Samuel Nello-Deakin, a postdoctoral researcher at the Autonomous University of Barcelona and lead author of the study. \u201cYou think that things are not as noisy as they actually are. So there\u2019s also this interesting interaction, right, between sort of what you hear and what you see.\u201d In addition, green spaces absorb city racket<\/a>, keeping it from bouncing off of and between buildings and pavement, insulating residents from the din.\u00a0<\/p>\n

With less commotion comes still more gains to public health. Noise pollution is an invisible crisis worldwide, as studies link the stress it causes not just to struggles with mental health, but physical problems like hypertension and heart disease<\/a>. By contrast, pocket parks and other green spaces encourage people to ditch their cars and move their bodies. \u201cThere are also physical health benefits from walking, biking, and being outside that over a lifetime tend to have a cumulative positive effect on what our society spends in health care,\u201d Galipo said.<\/p>\n

So as cities increasingly realize and utilize the power of greenery, the environmental, auditory, and social fabric of the urban landscape transforms. \u201cThere\u2019s a gravity to this green space that brings people out,\u201d Lambe said. \u201cAnd all of a sudden, neighbors are connecting, generations are connecting, cultures are connecting. Trees are about the one thing that everybody can agree on.\u201d<\/p>\n
