The concerns regarding limitation of water resources and environment have been on a rise for a few years now. The population across the world has increased significantly, owing to which, the existing resources are not able to meet the demands of people. This, in turn, has created the need for advanced solutions that are also sustainable for catering to the needs of people in a way that does cause any more harm to people. One of such solutions that have been developed recently is the concept of aquaponics. 

The system of aquaponics allows the farming of fish and plants together in a cycle that is beneficial for both. Waste that is produced by fish turns into ammonia and nitrates, and make great fertilizers for plants. Meanwhile, as plants utilize these nutrients, the water containing fish is purified. Aquaponics is quickly emerging as an environment-friendly and efficient way to produce food, as no chemical fertilizers are required for plants, unlike traditional farming practices. It is due to such advantages of this technology that the global aquaponics market is expected to advance at a significant rate in the years to come, as per a report by P&S Intelligence.  

Different types of aquaponics systems are deep-water culture, media-filled beds, and nutrient-film technique, out of which, the demand for media-filled beds is expected to increase significantly in the coming years. This is because of the fact that media-filled beds have a simple form, thereby increasing their adoption among farmers over other systems. In addition to this, this system enables plant roots to be exposed to air periodically, which prevent waterlogging. These systems are being utilized for producing different kinds of plants, including pepper, basil, cucumber, lettuce, kale, and tomato, and fish, including pacu, tilapia, goldfish, bluegill, koi, sunfish, and crappie. 

Aquaponics systems are highly suitable for remote locations that have inadequate farming conditions or areas that have cold climates, where vegetables are needed to be imported at high costs. Aquaponics offers food security at such places by ensuring round the years food production. Apart from all this, plants grow faster in these systems, which is attributed to the naturally fortified water from the fish tank. There is no need for a farmland with fertile soil or land for cultivating the yields which can be done on gravel, sand, or rocky surfaces. 

In addition to this, yield that is produced using aquaponics systems is healthier and organic. Geographically, North America is projected to emerge as a major aquaponics market in the years to come. This can be owing to the rising focus towards sustainable farming and increasing government support for the aquaculture society in the region. Other than this, the adoption of this technique is expected to rise in developing countries, including China, India, and Indonesia, in the near future due to rising concerns regarding shortage of resources. 

In conclusion, the demand for aquaponics is growing due to the shortage of water resources and increasing environment concerns.
