Dubai is already home to the world's biggest vertical farm — and it's set to beat its own record with GigaFarm, a 900,000 square foot facility that could replace up to 1% of food imports. Using growth towers supplied by Intelligent Growth Solutions (pictured), it will grow up to 3 million kilograms of fresh produce annually.

The food system is responsible for about a quarter of global greenhouse gas emissions, most of which are from animal agriculture. By reducing the need for livestock, lab-grown meant could help slow climate change. These nuggets were made from chicken cells cultured in a laboratory. Nicholas Yeo/AFP/Getty Images

Microalgae have health benefits, but they aren't to everybody's taste. To make microalgae appeal to the masses, German designer Malu Lücking developed a process for growing concentrated microalgae solution on edible agar jelly. The microalgae can be scraped off and eaten alone, or consumed with the jelly to function like a stock cube. Paul Cochrane

In many parts of the world, farmers must contend with intense heat, limited freshwater and sandy soil. In Dubai, the International Center for Biosaline Agriculture (ICBA) is growing salt-loving superfoods in an effort to expand food diversity in the region. CNN
ICBA has had success with Salicornia, a plant that thrives with saline water. It has potential as a fuel and as a food source, like this Salicornia burger. Showkat Rather/ICBA
