5.5 Conclusion
Research studies on the association between urban green space and health shows
that availability, proximity and use of urban green space such as parks or even allotment gardens, helps to improve the mental health of urban residents even when
controlling for socio-economic or socio-demographic confounders. Studies that
focus on other health outcomes, such as overweight or birth outcomes, show that
significant relationships partly disappear when statistical models are adjusted for
socio-economic variables. Income, deprivation or education are amongst the most
important variables that confound the green space–health-outcome relationship.
Nevertheless, a mediating role of urban green space for socio-economic inequality
in health outcome was identified. The results have led to important planning recommendations and directions for future research, which have been presented and discussed here.
This area of research is gaining widespread attention through the promotion of
the Sustainable Development Goals and related larger project financing, considering recent calls under the European Commission Research and Innovation
Programme. A number of important studies are expected to be conducted in the near
future.
