The role of aquaculture in ensuring the future supply of fish is undeniable. Aquaponics, a sustainable integration of aquaculture and hydroponics (soilless plant cultivation), creates a closed-loop system where nutrient-rich water from fish waste fertilizes plants, while the plants, in turn, purify the water for the fish. This symbiotic ecosystem exemplifies efficient water use and the principles of the circular economy. School Farming is an educational project launched in 2022 in Lisbon, Portugal, designed to inspire children’s interest in nature through hands-on learning. The project involves building an aquaponic system within a school, consisting of a fish tank, a plant-growing bed, and filtration and pumping equipment. Students actively participate in growing various vegetables, such as lettuce, basil, and peri-peri, with plant selection tailored to different school levels. This interdisciplinary program offers practical learning opportunities across multiple subjects, including biology, physics, chemistry, mathematics, and economics, among others. While School Farming serve as valuable learning tools in developed countries, its application in developing regions, where food insecurity is a pressing issue, could have a profound impact. By equipping children with practical knowledge and skills, school farming not only encourages small-scale replication at home but also fosters entrepreneurial thinking, helping to combat poverty and strengthen food resilience.
