Aquaponics and urban farms: a local, sustainable and profitable economy

How to eat responsibly tomorrow?

Aquaponics may not mean anything to you, but it is the future of agriculture. Indeed, these farms don’t need lot of space and water to be extremely productive and have a huge potential for automation. Saving between 90% and 95% of water while having a higher yield per square meter than a traditional garden, what is the secret of these new farms? Don’t worry, we’ll explain it all to you.

How does it work?

The principle of aquaponics is to connect a water-filled pool with fish to the place where the plants are. The goal is to recreate a complete cyclic ecosystem. The fish excrements (rich in nitrate) will load the water with important nutrients for the plant’s growth. Plants will be able to absorb nutrients from this water and then will purify it before let it return to the pond in which the fish are. All you need is a small pump to make the water circulate between the two pools. You see? That’s not so complicated!

A more responsible agriculture

The advantage of this type of cultivation is that it is an autonomous system, requiring little maintenance and it doesn’t need any fertilizer! It is therefore much easier to evolve towards an organic agriculture. This type of agriculture is very suitable for cities, needing little space. It allows to consume more local and fresh vegetables as well as to reduce the pollution of transport. For this reason, aquaponics has been on the rise for some years now, even in Berlin, with, for example ECF Farm or Farmly Place.

So, convinced by aquaponics?
