Seems like a very fancy concept given the term but Aquaponics might potentially be the future of eco-friendly farming.
Aquaponics is an environment-friendly practice in agriculture involving crop cultivation in a non-soil medium. Appropriate nutrient-rich solutions obtained from the excreta of the
cultured aquatic organisms, for example, fish are used. It refers to a food production system that couples aquaculture(raising aquatic animals such as fish, crayfish, snails, or prawns in tanks) with hydroponics (cultivating plants in water).
There are many benefits to aquaponic crop production such as:
• Increased plant growth rates
• Smaller production footprint than soil
• Reduced water resource inputs
• Reduction of plant pathogens.
Moreover, these plants tend to utilize fish excreta within a closed system making aquaponic food production is more sustainable and environmentally friendly than many other livestock or agricultural production systems.
Today, aquaponics is being implemented in several countries, from Myanmar to Peru, to Germany, even on the rooftops of Gaza. In the United States, a small number of backyard hobbyists have been experimenting with the system for years. Although, until recently, it hasn’t been tried on a large-scale commercial basis.
However, it cannot possibly replace soil farming anytime soon owing to the problems in large scaling and its inability to tolerate the growth of large crops as it takes a lot more water and nutrients.
Although it can still find use in family businesses for income and also in villages, enough to feed a small population of people where food happens to be scarce.
