Il verde nei giardini scolastici
Short description of the intervention
In 2023, the municipality of Cagliari initiated a project to transform 50 school gardens into vibrant, multifunctional outdoor spaces that enhance education and recreation. Co-funded under an EU program, this initiative aims to create environments where students can learn and play outdoors, taking advantage of the city’s favorable climate. The gardens are being upgraded with new features, such as trees, educational vegetable plots, diverse plant species, playground equipment, and furniture, to provide versatile spaces for learning, sports, and play.
Automated irrigation systems are being installed in each garden, conserving water by adjusting based on soil humidity and detecting leaks. This technological upgrade ensures efficient maintenance of the green spaces.
Overall, the project seeks to enrich the educational experience by integrating nature into daily school life. It aims to promote students' physical and psychological well-being through more opportunities for outdoor learning and activities, fostering a connection with nature, and improving the overall quality of the school environment (Refs. 1, 2, 3, 4 & 5).

Goals of the intervention
The intervention in Cagliari’s school gardens aims to:
Redesign 50 school gardens by planting several tree species and transforming the schools into multifunctional spaces that enhance education, recreation, and sustainability (incorporate sustainable practices, such as automated irrigation systems that conserve water by adjusting to soil humidity levels)
Create educational vegetable plots with diverse plant species that teach agricultural practices and promote environmental stewardship and provide children and young students with outdoor environments for hands-on learning.
Enhance appreciation for nature and biodiversity among students.
Improve student well-being by encouraging outdoor activities and sports. New playground equipment and furniture provide safe and engaging spaces for physical activity, supporting both physical and mental health. ((Refs. 1, 2, 3, 4 & 5)
Mental health and well-being objectives
The mental health objectives of the project for children include promoting emotional and psychological well-being by creating calming outdoor spaces where they can relax and reduce stress. Overall, the project aims to foster a strong connection to nature, enhancing mood and providing a positive, supportive environment for children (Ref. 2).
Mental health and well-being activities
The gardens are supposed to encourage social interaction through play and group activities, helping children build friendships and improve their social skills. Engaging with nature and hands-on activities like gardening should also support cognitive development and boost concentration and creativity. Additionally, outdoor play should increase physical activity, which is beneficial for both physical and mental health (Ref. 2).
Implementation activities and NBS focus
Implementation activities
The renovations covered a total area of 170,000 square meters, representing about 80% of school green spaces. Approximately 4,650 square meters of lawns, 50,000 Mediterranean shrubs and species were planted as part of the greening effort in these outdoor spaces. Every school created an educational garden where students planted, cared for, and learnt about vegetables and basic cultivation practices. Large gazebos were installed to provide shaded areas where students can gather, complete with seating and picnic tables for outdoor lessons and recreation. Each school was equipped with a sub-irrigation system connected to a water storage tank and a telematic detection system. The system monitors soil humidity, ensuring efficient water use by irrigating only when needed and alerting for any faults or malfunctions to avoid waste. Sports and playground equipment suitable for different age groups, was set up, along with safe areas featuring natural surfaces, synthetic turf, or anti-trauma grass.

Primary Beneficiaries
Specify primary beneficiaries
The primary beneficiaries of the Cagliari school garden redevelopment project are the young students who attend the schools involved. They gain access to enhanced outdoor spaces for learning, play, and physical activities, which support their educational, physical, and mental well-being. Teachers and school staff also benefit from improved environments that provide more opportunities for outdoor teaching and engagement. Additionally, families and the broader school community benefit from the enriched educational experience and the increased focus on sustainability and environmental stewardship (Refs. 1, 2, 3, 4 & 5).
Measures for inclusion of marginalised groups
"The intervention includes the provision of large gazebos that host the schoolchildren, protected by adequate shade and with the provision of furniture (seats and picnic tables). It also includes the provision of sports and play equipment, graduated for the various ages and the preparation of adequate areas with natural surfaces or synthetic or anti-trauma grass." (2)
