Aquaponics

Recirculation Aquaculture Systems (RAS) are a modern way to farm fish in indoor tanks within a controlled environment. These onshore systems purify and recycle water, use less feed, reduce parasites and diseases, eliminating antibiotic use. They avoid the environmental problems caused by offshore fish farming. Solid waste is recycled as biogas and fertilizer. Fresh fish are produced on limited land near to key markets thereby reducing land use and transport logistics, reducing CO2 emissions.

Hydroponics is a type of horticulture whereby a wide variety of crops are grown without soil by using nutrient solutions in water. The benefits of hydroponics include higher yields, reduced water consumption, less pesticide and herbicide use and less soil erosion. It is suited to most climates.
