Aquaponics is a sophisticated, integrated food production system that combines hydroponics and aquaculture. Aquaponics, as a combined approach integrating elements of both soilless culture and RAS, leverages the advantages of closed aquaculture systems. The goal of integrated agri-aquaculture systems is to increase food and nutrition security, reduce environmental footprint, and improve the adaptive capacities of farming communities to climate change. This approach is a form of sustainable intensification that produces more food from the same land, while also improving resource use efficiency, production, and household income. The adaptability of hydroponics to various environmental conditions makes it a compelling and sustainable choice for enhancing crop yields in both controlled and outdoor settings. Aquaponics is popular in Asia, particularly in China, Japan, and Thailand, for both commercial and small-scale operations due to its high yields and minimal water usage. In Africa, it is gaining traction for sustainable food production in regions with limited water resources, with small-scale operations established for community projects aimed at providing food and income.
