Do trees in the city make for healthier residents? That thought is obvious. But hard evidence for this is lacking. A recent article in Dutch newspaper NRC highlights various studies that show how nature can promote human health and well-being.
How does a green environment promote health?
Although much research points to a beneficial effect, many questions remain, says Sjerp de Vries, sociologist at Wageningen University & Research. How exactly does a green environment promote health? “The underlying mechanism is not yet known,” he says. “And you can say in general that green is good, but planners and policymakers want it more specifically.” Many cities are greening, but space is limited. So, how do you best create a park where people can not only recreate and exercise, but also relax? Does one large park work better than several small ones? Should all streets be greener?
Green schoolyards
To answer these and many more questions, a wide variety of studies and research have been conducted in recent years. For example, Jolanda Maas, associate professor at the VU in Amsterdam, conducted research into the effect of green schoolyards on primary school children.
We saw more versatile playing behavior on the green playgrounds and the girls moved more.
