The United Nations projects that global population will increase from 7 billion today to 9 billion by 2050, with 85 percent of people living in cities. Feeding all those people will be quite a challenge, but Dutch innovation could have a solution: vertical farming.

PlantLab has developed revolutionary technology to grow fruits and vegetables on a fraction of the land required for conventional farming. In fact, the farming can take place inside a high-rise building using LED technology in place of the sun and using 90 percent less water than traditional agricultural practices.

The company combines state-of-the-art technology and knowledge of plant physiology to build a closed growing environment, a “Plant Production Unit,” to optimize and control growing conditions.

A Plant Production Unit can produce crop yields that are two to three times higher than the best greenhouse, and 30 to 40 times higher than an open crop field. Growing 7 ounces of fresh fruits and vegetables for one person every day for a year requires just 10 square feet of space.
