In January 2024, the municipality of Cagliari inaugurated three new green areas in the city, adding five and a half hectares of green spaces for residents to enjoy. These areas are located between Keplero, Avicenna, and Parigi streets, not far from the city center (Refs. 1 & 2). The primary goal of this initiative is to mitigate the effects of climate change, particularly rising temperatures. The green areas are designed to reduce the city's heat island effect and contribute to carbon sequestration. The planting of new trees will also help maintain ecosystems and improve environmental conditions in targeted areas . Special attention was given to soil quality, with most projects incorporating walkways equipped with drainage systems (Refs. 1, 2, & 4). Additionally, the new infrastructure aims to foster social engagement and attract more citizens, who will benefit from these improvements. (Refs. 1 & 2). This initiative is also expected to boost the local economy by encouraging the development of small complementary services (Ref. 3). It is part of a larger municipal project co-funded by the EU.
