Our initiative (Avenir Vert Solidaire) through aquaponics aims to ensure food self-sufficiency for orphanages by supplying their collective kitchens with fresh and healthy products. The orphans actively participate in managing these sustainable farms, learning about aquaponics principles, the life cycles of fish and plants, and contributing to food production for their own meals. This involvement fosters a deep understanding of agroecology and raises awareness of sustainability within the educational community.

Aquaponics is an innovative system that combines hydroponics and fish farming. Fish waste, processed through nitrification, is absorbed by the plant roots, which in turn purify the water before it returns to the fish tanks.
