imply put, vertical farming is the idea of filling a skyscraper with crops, rather than spreading it across the land. Doing this saves land space, and can provide big cities with locally-grown veggies. Often they’re aquaponic vegetables, meaning they’re grown in water.
See how one man in Oakland made his own aquaponic farms—this design could be used for a personal vertical farm.
The world’s very first commercially-made vertical farm just opened in Singapore, a small Asian country with only 271 square miles of land (most of which is urbanized or developed, so they don’t have much room for farming). They’re not aquaponic, but instead grown in soil. Check out this news tidbit:
Besides being sustainable (after the initial cost to build such a farm), vertical farms help make cities more self-sufficient, because they no longer have to import as much from other places.
Vertical farming will quickly become a large market, and a big market means a lot of engineers working hard to come up with the best ways to grow vegetables like this. If you care about helping the environment, and like helping things grow, try building an aquaponic farm at your house and see if you might like it as a job.
