Urban farming - the future of agriculture

Despite the fact that scientists many times warned that the overpopulation of the planet threatens humanity with various “heavenly punishments”, this did not stop the growth of the population. There are more and more people, which means that they consume much more significant amounts of food than before. Unequal distribution of resources leads to the fact that millions of people around the world are starving.

This applies to many countries and regions, both large settlements and suburbs. Nevertheless, food is produced much more than before, now there is a maximum. New technologies can solve the problem of shortage of food, and not only purely technological tools, but also new approaches to agriculture are needed.

New heights

One of these approaches is the cultivation of food in the city. In the locality, this work can be practically the same as those cottages and vegetable gardens that many people have. But it can be different if you choose vertical multi-level trusses as a basis. Such “lands” can be configured as you like, but in most cases we are talking about “beds” suspended in the air, where crops are grown on special substrates or without them. On such farms, as a rule, there is ultraviolet radiation, which emulates the rays of the sun. And instead of unpredictable weather conditions, which sometimes lead to catastrophic situations on the fields, virtual farms within the city limits are completely manageable - the “climate” here is controlled by a computer, and everything is aimed at obtaining the maximum yield.

In principle, if there are appropriate technologies, then farms of this kind can be created almost everywhere. In fact, we are talking about the "new trend" - urban farms that are in close proximity to those for whom food is grown. True, there are a number of conditions. All vertical farms need a certain space and access to electricity. Nothing more is needed. Farmers themselves can buy everything they need for food production.

Start can be very easy - all that is required to the "urban farmer" is in any store of building materials and agricultural shops. Under such conditions, the number of farms is constantly growing - for example, there are hundreds or even thousands of large and small farms in the USA.

They need volume, not square, because everything here is expressed in cubic, not square meters. As a result, much more products can be grown on a vertical farm than non-ordinary ones, if we talk about the same usable area.

Growing on vertical farms can not only fruits and vegetables. Urban Organics, for example, produces plants and fish (salmon) on its farms. All thanks to a technology called aquaponika. These are closed systems where plants contribute to the growth of fish, and those provide the useful elements of the plant.

The same company, which was discussed above, in 2014 began to brew its own beer, creating miniature breweries. Also in 2014, Urban Organics was named the Guardian newspaper one of the most innovative among all the agricultural organizations in the world.

It should be noted that vertical farms are also “friendly” to the environment. Aquaponic systems produce very little non-recyclable waste that cannot be used further. Well, the placement of farms close to consumers allows you to avoid the formation of large transport schemes for the delivery of products.

Well, are there any difficulties?

Yes of course. If you create a large multi-level farm, you will have to find a fairly spacious, perhaps a multi-storey room where you can grow a large amount of food.

This problem is gradually leveled as there are companies that provide assistance to farmers who want to create their own vertical fields. One such farm is called Agritecture Consulting . At the moment, she has helped a dozen major projects and continues to provide assistance.

Such companies are likely to appear more and more over time. They are really great make life easier for "urban farmers".

Volumes of production

How much a city farm can produce products can be shown on the example of the same Urban Organics. So, last year the company opened a new farm , much larger than all the others. Its capacity is about 124 tons of fresh fish and 215 tons of plants per year.

This vertical farm was located in the former brewing complex. “We not only produce products, but also give jobs, create jobs,” said the head of the company.

According to him, if there are a lot of urban farms, this will help to create communities of urban residents in the future, whole districts that provide themselves, that is, they can be called autonomous.

The creation of new agricultural communities can and should involve new members - he is also sure of this. And this also contributes to the Internet. For example, on a site called Plus.farm, everyone can find “accomplices,” companions who also want to create and work on a vertical farm. People creating such farms on the basis of ready-made technologies often improve them - they develop the best lighting systems, sensors, and plant growing schemes. At the same time, not everyone considers such things to be their own intellectual property, for which you have to pay - information about successes with technical data is disseminated in various forums and social networks.

Farms of the future

If people continue to develop this area, then after a while it will be possible to talk about the global community. Gradually, this area is becoming more developed, it includes new players.

In the village, a large farm of this kind can be a tool for obtaining food, as well as an incentive for the city's economy - after all, new jobs are created, and there may be a lot of them.

Creating such enterprises, it is worth paying attention to the region itself. For example, while there are so many fields that cope with their task - providing people with food, vertical farms may not be an urgent need. But in poor countries, regions where agriculture is underdeveloped and there is a shortage of food - there such companies can be very, very necessary.
