When it comes to maintaining respiratory health, living in an environment with good air quality is clearly an important factor. In many urban areas inhabited by low-income populations, this clean air is nowhere to be found. Having green space within a city can play a significant role in reducing air pollution as well as mitigating the dangerous urban heat island effect. The need for green space is often recognized in more affluent parts of a city, while low-income areas are neglected. When these less affluent communities are overlooked, there can be serious health consequences such as the extreme disparity in negative asthma outcomes in the black and Hispanic children who inhabit these neglected areas.  In this article, Planet Forward and the National Society of Landscape Architects examine the benefits that parks can have for the health and prosperity of low-income urban communities.

Many U.S. cities don’t offer all of their various communities equal access to green space. For example, Los Angeles has 23,000 acres of parks, which puts the city in the top 15 in terms of total green space, but much of this parkland is near the mountains so most of the city’s low-income, inner-city communities don’t have any parks at all. According to Peter Harnik, director of the Center for City Park Excellence at the Trust for Public Land, in reality 3.8 million residents in L.A. are too far from “a park to use one easily, conveniently, or frequently.”

Similarly, in New York City, high-quality parkland is found in greater abundance in wealthier districts, while low-income communities don’t enjoy the same access. More than half of the city’s 59 community board districts were found to have less than 1.5 acres of parkland per 1,000 residents.

A University of Chicago study found that communities with lower incomes, higher poverty rates, and higher proportions of racial and ethnic minorities also had the “fewest opportunities for community-level physical activity.” Lack of green space is then not just about fairness, it’s about health. Low-income communities may have higher rates of health problems like obesity and asthma in large part because they don’t have parks.

New parks can sprout up in the unlikeliest places. Low-income, inner-city communities are characterized by hardscapes – asphalt surfaces. When a community organizes and creates a plan for a new park, local governments can respond and purchase asphalt-covered areas like parking lots and transform them into public community parks. The cost of an average neighborhood park can run into the millions, but including a park budget in the initial master plan helps ensure local governments will finance it, and even partner with developers, local foundations, or conservancies to get it built. These types of projects can also come about if they are part of broader public-private urban redevelopment schemes aimed at providing housing, improving access to transit, and investing in the local environment. Transportation infrastructure like boulevards, rail lines, and trails can be expanded, greened, and designed to become easily-accessible parks. Even landfills, rooftops, reservoirs, and cemeteries can be turned into parks.

Park design needs to be compelling so people visit and forge community ties there. Parks that are designed for local residents and include these residents in the design process are often the most successful. New York City’s famed Central Park, designed by ASLA founder Frederick Law Olmsted, and Bryant Park, designed by Laurie Olin of FASLA are two examples of great community parks designed for people. The 843-acre Central Park has many functional areas, including game fields, gardens, skating rinks, a boating lake, and winding paths that offer “dozens and dozens of different kinds and moments of experience,” says Sarah Goldhagen, architecture critic for The New Republic. Bryant Park’s movable café table and chairs set under a rich tree canopy and spread around a central lawn enable people to easily form groups or stay on their own. The park is now viewed as a model for how public places can facilitate human interaction.

Human interaction isn’t just needed to make a popular and sustainable park. New research demonstrates that people with strong community ties also live longer, healthier lives. Parks provide the space for communities to form.
