Researchers show positive effect of urban nature on mental health.<\/p>\n\n\n\n

Daily contact with trees in the street may significantly reduce the risk of depression and the need for antidepressants. This is the result of a study by researchers at the Helmholtz Centre for Environmental Research (UFZ), the German Centre for Integrative Biodiversity Research (iDiv), Leipzig University (UL), and the Friedrich Schiller University Jena, recently published in the journal Scientific Reports<\/em>. Street tree planting in residential areas of cities may be a nature-based solution to reduce the risk of depression with added benefits of also addressing climate change and biodiversity loss. This should be taken into account by urban planners, health professionals, and conservationists.<\/p>\n\n\n\n

Depression, especially in urban areas, is on the rise, now more than ever. Mental health outcomes are influenced by, among other things, the type of environment where one lives. Former studies show that urban greenspace has a positive benefit on people experiencing mental ill health, but most of these studies used self-reported measures, which makes it difficult to compare the results and generalise conclusions on the effects of urban greenspace on mental health.<\/p>\n\n\n\n

An interdisciplinary research team of UFZ, iDiv, the UL, and the Friedrich-Schiller-University tried to improve this issue by involving an objective indicator: prescriptions of antidepressants. To find out whether a specific type of \u2018everyday\u2019 green space \u2013 street trees dotting the neighbourhood sidewalks \u2013 could positively influence mental health, they focused on the questions, how the number and type of street trees and their proximity close to home correlated to the number of antidepressants prescribed.<\/p>\n\n\n\n

The researchers analysed data from almost 10,000 Leipzig inhabitants, a mid-size city  in Germany, who took part in the LIFE-Adult health study running at the University of Leipzig Medical Faculty. Combining that with data on the number and species type of street trees throughout the city of Leipzig, the researchers were able to identify the association between antidepressants prescriptions and the number of street trees at different distances from people\u2019s homes. Results were controlled for other factors known to be associated with depression, such as employment, gender, age, and body weight.<\/p>\n\n\n\n

Street trees near the home may reduce the risk to suffer from depression<\/h5>\n\n\n\n

More trees immediately around the home (less than 100 meters) was associated with a reduced risk of being prescribed antidepressant medication. This association was especially strong for deprived groups. As these social groups are at the greatest risk for being prescribed antidepressants in Germany, street trees in cities can thereby serve as a nature-based solution for good mental health, the researchers write. At the same time, street trees may also help reduce the \u2018gap\u2019 in health inequality between economically different social groups. No association of tree types, however, and depression could be shown in this study.<\/p>\n\n\n\n

\u201cOur finding suggests that street trees \u2013 a small scale, publicly accessible form of urban greenspace \u2013 can help close the gap in health inequalities between economically different social groups,\u201d<\/em> says lead author of the study Dr Melissa Marselle. \u201cThis is good news because street trees are relatively easy to achieve and their number can be increased without much planning effort.\u201d<\/em> As an environmental psychologist, she conducted the research at UFZ and iDiv and is now based at the De Montford University of Leicester, UK. Marselle hopes that the research \u201cshould prompt local councils to plant street trees to urban areas as a way to improve mental health and reduce social inequalities. Street trees should be planted equally in residential areas to ensure those who are socially disadvantaged have equal access to receive its health benefits.\u201d<\/em><\/p>\n\n\n\n

\u201cImportantly, most planning guidance for urban greenspace is often based on purposeful visits for recreation\u201d<\/em>, adds Dr Diana Bowler (iDiv, Friedrich-Schiller-University, UFZ), data analyst in the team. \u201cOur study shows that everyday nature close to home \u2013 the biodiversity you see out of the window or when walking or driving to work, school or shopping \u2013 is important for mental health.\u201d<\/em> This finding is especially now in times of the COVID-19 lock-downs, Bowler adds.<\/p>\n\n\n\n

Urban tree planting can help to meet nature protection goals and social equality<\/h5>\n\n\n\n

And it\u2019s not only human health which could benefit. \u201cWe propose that adding street trees in residential urban areas is a nature-based solution that may not only promote mental health, but can also contribute to climate change mitigation and biodiversity conservation,\u201d<\/em> says senior author Prof Aletta Bonn, who leads the department of ecosystem services at UFZ, iDiv and Friedrich-Schiller-University. \u201cTo create these synergy effects, you don’t even need large-scale expensive parks: more trees along the streets will do the trick. And that\u2019s a relatively inexpensive measure.\u201d<\/em><\/p>\n\n\n\n

\u201cThis scientific contribution can be a foundation for city planners to save and, possibly, improve the life quality for inhabitants, in particular, in densely populated areas and in central city areas,\u201d<\/em> adds Prof Toralf Kirsten from Leipzig University. \u201cTherefore, this aspect should be taken into account when city areas are recreated and planned, despite high and increasing land cover costs. A healthy life of all living being is unaffordable.\u201d<\/em> Information<\/p>\n\n\n\n
