In addition to helping maintain a city appealing, parks, tiny wooded areas, and even simple patches of grass help individuals find happiness in the otherwise hectic urban environment. We can now better design and keep an eye on these urban “green areas” thanks to modern technology. As several studies have shown, nature in urban settings is essential in addressing many of the problems with global public health that are frequently connected to urbanization. Diseases like depression and high blood pressure are included in this.
According to a 2022 study, trees can enhance urban air quality by trapping toxins in their leaves and pine needles. Therefore, it is not a particularly controversial topic to say that cities do require green places. The ideal amount of green space for a city is still up for debate. Even here, science can offer some suggestions, since evidence suggests that each person needs at least 9 square meters of green space, with 50 square meters per capita in a metropolis being ideal. Therefore, the crucial query is: What type of green space do we want? An attractive park that was created by humans? Or perhaps something more wild and unmaintained, like woods, meadows, or open spaces that resemble fields?
This is primarily dependent on the geographical circumstances of the city in question, as we explore in our upcoming book, Designing Smart and Resilient Cities for a Post-Pandemic World: Metropandemic Revolution. However, it is unavoidable that some cities are blessed with lush vegetation while others are not, despite the World Health Organization’s (WHO) recommendation for a diversity of different types of green places. Rather than focusing on parks, Treepedia concentrates on pedestrian street trees that may be found in many cities all over the world. The primary reason is that, in contrast to parks, where most people actively want to be there, pedestrians are more likely to observe street trees without intending to. Treepedia enables the general public to estimate the amounts of tree coverage for their respective city or region using an open-source framework. Urban green areas should have a bright future if urban planners learn to use digital technologies more effectively. But creating the ideal green space we desire for our cities would also necessitate closer future cooperation between urban planners and engineers.
