Green space & parks

Evidence Rating

Some Evidence

Health Factors

Communities can increase green space and parks by creating new parks or open spaces, renovating or enhancing under-used recreation areas, or rehabilitating vacant lots, abandoned infrastructure, or brownfields. Rails to trails programs, brownfield redevelopment, community gardens, and park enhancements are examples of efforts to increase recreational green space, trails, and parks. Such efforts can be applied to spaces accessible by foot, bike, and other types of transportation, and are frequently implemented in low income neighborhoods.

Expected Beneficial Outcomes (Rated)

  • Increased physical activity

Other Potential Beneficial Outcomes

  • Reduced obesity rates

  • Improved mental health

  • Reduced crime

  • Reduced stress

  • Improved birth outcomes

Evidence of Effectiveness

There is some evidence that increasing green space and parks increases physical activity (, , TRB 2005, CDC MMWR-Khan 2009, Cohen 2012, , AHA-Mozaffarian 2012), especially among children and adolescents (, Cohen 2006, Almanza 2012). Additional evidence is needed to confirm effects.

Living in close proximity to green space and parks has been shown to lower childhood obesity rates, with larger effects for boys than girls (), and to increase physical activity among both boys and girls (Cohen 2006, ). Children’s moderate to vigorous activity levels appear to be greater outdoors than indoors (Dunton 2011). Access to green space may also increase physical activity levels for adults (, TRB 2005, ).

Enhancing parks with outdoor exercise equipment can increase physical activity levels and new park users, and appears to be a cost-effective approach in densely populated areas with limited exercise facilities (Cohen 2012). Increasing green space and parks in conjunction with physical activity progams () and efforts to address potential safety and security concerns in surrounding communities may be more effective at increasing physical activity levels than increasing green space alone (TRB 2005).

Increasing green space, parks, and trails can have additional environmental and social benefits for communities (Sallis 2015). In some circumstances, proximity to green spaces has been shown to reduce socio-economic disparities, and has been associated with lower stress (, , , ), improved ADHD symptoms and mental health (Sallis 2015), and reductions in domestic violence and other crimes (UN IL-LHHL). In an Israel-based study, proximity to green space has been associated with increased birthweight and reduced risk of low birthweight, especially for low income mothers (). Living in neighborhoods with a high density of trees is also associated with improved health perceptions and health outcomes (Kardan 2015).

Impact on Disparities

Likely to decrease disparities

Implementation Examples

Several states have taken action to increase green space and parks by supporting new recreational trails, as in Illinois, Minnesota, and Virginia. The Mississippi state legislature authorized the city of Pascagoula to use food tax revenue to implement a comprehensive parks and recreation master plan (NCSL Winterfeld-Obesity prevention 2014). Brownfields redevelopment (US EPA-Brownfields), community gardens (ACGA), and Rails to Trails programs are implemented to some degree in all 50 states (RTT).
