An ambitious push to create more green spaces in Barcelona – a city with one of the highest population and traffic densities in Europe – could improve the health of more than 30,000 people, reduce the use of antidepressants and save up to €45m (£40m) annually in costs associated with mental health issues, research suggests.
It builds on a growing body of evidence that has linked urban green spaces to better mental wellbeing as well as the prevention of depression, anxiety and insomnia.
