The final phase is dedicated to reflection and envisioning the future. Students compare their systems: which ones work best? What difficulties did they encounter? What improvements would they suggest?

Creativity takes shape through an augmented reality activity: they design an “eco-building” – a building of the future that integrates aquaponics systems to produce food and purify water. Thus, aquaponics leaves the laboratory tank and becomes a concrete idea of sustainable architecture.

The final discussion links the experience to the Sustainable Development Goals (SDGs): how can aquaponics help ensure clean water, healthy food and resilient cities? What are the limitations of this technology?
