Aquaponics is an artificial ecosystem. In it, a
person himself (aquaponist) balances the impact of
abiotic components (temperature, light, water
hardness, pH, etc.) on biotic components.
The world has already learned how to use
aquaponics. So, the largest farming project in Europe
is a vertical farm in Hague in the former six-story
Phillips office, vegetables and microgreenery are
grown on the roof, and fish are fed on the 6th floor
below.
Ideally, city farming solves the following tasks:
ensuring food and economic security of the
country, including import substitution of
products;
year-round cultivation of fresh and useful
agricultural crops, without chemical fertilizers
and additives;
presentation of a wide range of agricultural
products;
increasing the yield of crops cultivated
regardless of weather (external) conditions and
human factor;
saving water, in fact, 95% less water is
consumed, than when cultivating crops in the
ground;
fast delivery to the consumer, logistics and
resources saving;
saving space due to close and story placement
of agricultural crops;
saving land area, water reservoirs;
reducing the time and physical spendings for
cultivation of crops;
forming ecological thinking;
the forming a healthy lifestyle;
automated cultivation and tendance.
However, it should be noted a number of
difficulties, arising in the running city farming, which
must be taken into account by the entrepreneur in the
course of planning and organizing a social enterprise:
rather large financial costs for the purchase and
maintenance of special automated equipment
and devices;
equipment failure leads to a large loss of yield;
the penetration of viruses and bacteria
contributes to the complete loss of yield;
manual pollination of crops;
large yields can be obtained only when using
greenhouses, and it is rather difficult to work in
them due to high temperatures and humidity;
crops cultivated may still contain pesticides
and nitrates, that unprincipled farmers add to
nutrient solutions. This is why many
consumers are distrustful of products,
cultivated without soil;
lack of highly qualified personnel by
profession of "City farmer".
Thus, the profession "City farmer", according to
the Atlas of new professions, posted on the website
http://atlas100.ru/catalog/selskoe-khozyaystvo/, will
officially appear in Russia before 2021.
In a number of regions of our country (Bryansk
region, Vladimir region, Voronezh region, Moscow,
Novosibirsk region, Nizhny Novgorod region), work-
study sites (centers) are actively being created, where
students, youth, unemployed citizens have the
opportunity to get additional education by profession
of "City farmer". Students acquire the skills to work
on metalwork, soldering, electrical equipment, master
the work with measuring instruments, installations
for the preparation of solutions of a given
concentration, study marketing, management,
principles of operation of modern equipment
(automated greenhouses, hydro, aero or aquaponic
systems).
All equipment for city farms is developed using
digital technologies and innovations, systems are
controlled through an integrated network by special
consoles, smartphones, electronic devices, and digital
signals are coming directly to personal switches
(described above). This equipment is mainly
produced abroad (city farms from the companies
Tower Garden, Philips, Naava, Click & Grow
(average cost is 4,800,000 rubles), but Russian
developments also appear (Troysun smart home farm,
"CityFerma" (average cost is 2,500,000 rubles).
Automated phytomodules, phytocabinets,
phytoboxes (price range is from 3,000 to 80,000
rubles) are also popular.
Digital city farming is a popular niche for social
entrepreneurship, whose activity is aimed at
achieving socially useful goals and solving social
problems of society (Federal Law, 2019).
Let us consider the main characteristics of the
projects “Digital City Farming: Hydroponics”,
“Digital City Farming: Aeroponics”, “Digital City
Farming: Aquaponics”, which are possible for
implementation, which have a social orientation and
imply the appearance of visible social effects.
Our main consumers:
socially vulnerable and seeking help people
(single parents and parents with many children,
low-income citizens, disabled people and
persons with disabilities, parentless children,
pensioners and people nearing pension age);
