One of the problems that we will have to face sooner rather than later is that of procuring food for a population that, not only continues to grow, but will also be concentrated in megacities.
By 2050, the world human population is estimated to reach 10,000,000 (ten billion), due to urbanization and industrialization, arable land decreases more and more.
One of the solutions proposed is vertical farms consisting of plant crops within skyscrapers or farmscrapers, which would function as greenhouses using technologies such as hydroponics or aeroponics.

For those who live near the sea or some large area of water, the idea that we bring to this blog today could also be an interesting solution.
They are basically islands designed to float and keep all kinds of crops inside, of course these islands would be self-sustaining and could produce up to 20 tons of vegetables a day.
Each module measures 200 × 350 meters and it is estimated that it can produce 8,152 tons of vegetables and 1,703 tons of fish per year, since it can also function as a fish farm.
One of the biggest advantages is that these islands can be built anywhere in the world and bear fruit even in areas unsuitable for agriculture.

These units are made up of three levels, a roof covered with photovoltaic panels, rain collectors, wind turbines, etc.
The intermediate level would be the orchard itself, using hydroponic and aeroponic techniques, and a fish farm would be housed on the third level, in addition to a desalination plant.
This also has an additional advantage and is that, by bringing crops closer to consumers, the cost of transport is much less, as is the environmental impact of road transport.
