Urban sprawl is a big problem in cities, but creating more green spaces can help control it. By making vacant land more attractive with parks and forests, we can encourage people to live closer together in the city instead of spreading out. This method also helps improve air quality and protect biodiversity. A study in Romania found that planning new green spaces based on criteria like climate regulation and biodiversity conservation can be effective in fighting urban sprawl. The study identified suitable types of green spaces and available land for future development. This approach can be a useful tool for cities to plan green spaces and combat urban sprawl.
