Figure: Overview of urban nature-based solutions (NbS) cases identified in this study. A) Geographical distribution of identified cases, per country and city. B) Frequency of cases per NbS type (n = 185). The NbS are distinguished based on whether they involve measures or not. C) Crosstabulation of NbS types (vertical) and measures applied in those NbS units (n = 42).

DID YOU KNOW?

Cities don’t have to be concrete jungles - they can be living ecosystems! New global research conducted by Li et al. from the Institute of Environmental Sciences (CML), Leiden University, in the Netherlands, shows that nature-based solutions (NBS) like parks, gardens, green roofs, restored rivers, and native grasslands can boost wildlife even in the busiest urban centers. In fact, 78% of NBS projects studied improved biodiversity, helping plants, insects, birds, and other species thrive in cities. Even more exciting: in some cases like USA, Australia, China, Germany, or India, city NBS performed just as well as natural areas in supporting diverse life! These findings show that when we bring nature back into cities, we’re not only helping the planet — we’re also improving our own well-being. Cleaner air, cooler neighborhoods, and more beautiful spaces to play and relax… all thanks to smart use of urban nature. So the next time you see a green roof or pollinator garden, remember - it’s not just pretty. It’s powerful.
