How the Internet of Trees can make our cities greener

Parks, small forests, and even simple patches of grass not only maintain a city’s appeal, but also help people find a sense of happiness in an otherwise bustling urban environment. With new technologies, we can plan and monitor these urban “green spaces” better than ever.

like several studies have highlighted, nature within urban settings plays a critical role in combating many of the global public health challenges commonly associated with urbanization. This includes diseases such as depression and high blood pressure. A 2022 study showed that trees actually have the ability to improve urban air quality as the leaves and pine needles capture pollutants from the air.

That cities need green spaces, therefore, is not a particularly controversial issue. However, it is an open question how much green space a city should have. Even here, science can provide some guidelines, such as research aims for at least 9 square meters of green space per individual, with an ideal value of 50 square meters per capita in a city (for comparison, an average car parking space in the UK takes up approx. 12 squares meters).
