How is aquaponics a sustainable form of agriculture




Aquaponics /ˈækwəˈpɒnᵻks/, refers to any system that combines conventional aquaculture (raising aquatic animals such as snails, fish, crayfish or prawns in tanks) with hydroponics (cultivating plants in water) in a symbiotic environment. In normal aquaculture, excretions from the animals being raised can accumulate in the water, increasing toxicity.

farming is a method of sustainable agriculture that forms a symbiotic relationship between fish and plants. It involves the use of a fish tank placed below a grow bed for plants, where the main input to the system is fish food.

Aquaponics combines the hydroponic production of plants and the aquaculture production of fish into a sustainable agriculture system that uses natural biological cycles to supply nitrogen and minimizes the use of nonrenewable resources, thus providing economic benefits that can increase over time.

Is aquaponics sustainable agriculture?

Aquaponics farming is a method of sustainable agriculture that forms a symbiotic relationship between fish and plants. It involves the use of a fish tank placed below a grow bed for plants, where the main input to the system is fish food.

How can we make aquaponics more sustainable?

Saving water Locations with significant water pollution or contamination should have adequate filtration in place before installing an aquaponic system. But the fact that less than 10% of the water used in traditional agriculture is needed, will allow that filtered water to grow a lot more in aquaponics than in soil.

Why is aquaponics considered to be a method of sustainable food production?

Since aquaponics can be done indoors, crops can be grown year round due to their independence of weather and climate. Additionally, plants can grow twice as fast due to the natural fortification of the water and the nutrients obtained from fish waste [9, 10].

Is aquaponics self sustainable?

Why is aquaponics important to the future of farming?

Advantages of aquaponics include crop production at least ten times higher than traditionally farmed plots of equivalent size, 85-90% less water consumption than traditional irrigation, low energy consumption, year-round crop production and flood and drought resilience.

What is aquaponics in agriculture?

A combination of fish and plant production using aquaculture and hydroponics systems, aquaponics is moving from the realm of experimental to commercial. Learn more about this production system and if it might be right for your backyard garden or farming operation.

How does aquaponics benefit the economy?

Some of the benefits of commercial aquaponics production systems compared to typical agricultural production include reduced water use, reduced land footprint, reduced energy use, increased yields, and improved traceability.

Is hydroponic farming sustainable?

Hydroponic plant cultivation is widely considered more sustainable than regular farming as it uses around 90% less water. Secondly, hydroponic farming yields more vegetables and herbs in a shorter time. Thirdly, its carbon footprint is minimal as the greens are grown locally.

What is aquaponics farming?

Aquaponics is a form of agriculture that combines raising fish in tanks (recirculating aquaculture) with soilless plant culture (hydroponics). In aquaponics, the nutrient-rich water from raising fish provides a natural fertilizer for the plants and the plants help to purify the water for the fish. Aquaponics can be used to sustainably raise fresh …

What is the only input to aquaponics?

The only input into an aquaponics system is fish food. The fish eat the food and excrete waste, which is converted by beneficial bacteria to nutrients that the plants can use. In consuming these nutrients, the plants help to purify the water. You cannot use herbicides, pesticides or other harsh chemicals in an aquaponics system, …

How many issues are there in Aquaponics Journal?

Nelson and Pade, Inc.® began publishing the Aquaponics Journal ® in 1997 and continuously published it through the beginning of 2013. There are a total of 62 issues, all of which are available as a downloadable .pdf collection.

Why is fish considered a sustainable system?

Fish are free of growth hormones and antibiotics. Allows continuous production of food. Produces both a protein and vegetable crop. Integrated system is sustainable and earth-friendly. Eliminating soil eliminates soil borne diseases. When combined with Controlled Environment Agriculture, you can grow year ‘round in any climate.

Is aquaponics a year round system?

What is aquaponics farming?

One of these methods involves fish. Aquaponics farming is a method of sustainable agriculture that forms a symbiotic relationship between fish and plants. It involves the use of a fish tank placed below a grow bed for plants, where the main input to the system is fish food. When the fish produce waste, it is cycled out of the fish tank into …

Why is aquaponics important?

To improve global food systems and decrease food insecurity, it is more important than ever for people to practice sustainable agricultural development. To learn more about how aquaponics can aid in the production of sustainable food systems, Global Citizen spoke to Yemi Amu, founder and director of Oko Farms, an aquaponics farm …

Where did aquaponics originate?

Aquaponics also has roots in Southeast Asia, where farmers cultivated rice and fish concurrently, according to the United Nations’ Food and Agriculture Organization. The practice of raising fish in rice fields became one of the best examples of polyculture farming as a method of sustainability. Photo courtesy of Oko Farms.

When did hydroponics become popular?

Around 2011, hydroponics [using nutrient-rich water for agriculture instead of soil] was becoming popular, and I thought it was so great to throw aquaponics in the mix. The system can work indoors or outdoors, it saves water, and Oko Farms was built a couple of years later.

When did aquaponics start?

The practice of aquaponic gardening can be traced back centuries. In central Mexico around 1000 AD , the Aztec people developed a technique known as chinampa to expand their growing efforts to the surface of lakes and ponds, according to the Permaculture Research Institute.

How does fish waste get cycled out of the fish tank?

When the fish produce waste, it is cycled out of the fish tank into the grow bed, where bacteria transform ammonia into nitrates that plants need to grow. The water is then filtered and returned to the fish tank, aiding in the highly optimized, zero-waste process of farming fish and plants together.

Does aquaponics require a lot of land?

It doesn’t require a lot of land, it saves water. Water access is limited for a lot of people around the world, and we use a lot of water in agriculture specifically. Aquaponics can address this problem because it requires very little input of water.


Aquaponics is a food production system that aims higher sustainability by integrating advantages gained from aquaculture and hydroponic production. Aquaponics aims to mimic the biological process that happens in the natural environment in a controlled production system.

1. Introduction

The population of cities has increased substantially over the last decades ( UN, United Nations et al., 2018 ). Urbanization has become a major global trend, and supporting it demands provision systems for infrastructure, logistics, communication, commerce, cultural aspects, tourism, and employment generation ( Leamer and Storper, 2014 ).

2. Methods

The farms were chosen based on the study carried out by Portella et al. (2019), who conducted a nationwide data survey to identify Brazilian aquaponics producers and their main management practices.

3. Results

Farm A demanded a 6.3 times less emergy density than Farm B to keep the system running for one year ( Table 3, Table 4, respectively). The resources from the larger economy had the highest proportion of emergy inputs in both farms. The materials were the most responsible for this high representation (93% for Farm A and 99% for Farm B).

4. Discussion

This study intended to assess the sustainability of two urban aquaponics farms in Brazil. It is important to emphasize that both farms used management and structures that are well accepted and adopted in the world of aquaponics.

5. Conclusion

We presented the first emergy synthesis of urban aquaponics farms and gave relevant insights to discuss its environmentally sustainable character. The primary purpose of this study was to investigate and compare the sustainability of two urban aquaponics farms using emergy synthesis.
