Aquaponics-Ecological Integration of Aquaculture and Crop Cultivation for Food Sustainability

Ankur Rajbongshi

Aquaponics is an integrated food production approach that combines aquaculture and hydroponics into a single recirculating system, where fish and plants are grown together in a mutually beneficial environment. This method utilizes fish waste as a nutrient source for plants, while plants purify water for fish, thereby establishing a closed loop ecological system. Aquaponics has gained increasing global attention due to its potential to enhance food security, conserve water, optimize space utilization, and reduce dependence on synthetic fertilizers. The system is particularly relevant in regions facing land degradation, water scarcity, and rapid urbanization. A comprehensive understanding of aquaponic principles, components, biological interactions, system designs, advantages, challenges, and future prospects is essential for promoting wider adoption. Emphasis is placed on sustainability, productivity, and environmental benefits supported by current scientific literature, along with its relevance in climate resilient agriculture and urban farming systems.
