Amid a worsening climate crisis, technology has a vital role to play in ensuring we can produce enough food for a rapidly growing population.

Located off the coast of Noli, Italy, Nemo's Garden is the world's first underwater cultivation system for terrestrial plants. It consists of an array of floating dome-shaped greenhouses, which are anchored to the sea floor.
Weeding robots could reduce the need for farm workers, and allow precision protection of crops. Pictured, a weeding robot at an agricultural research farm in eastern France.

Autonomous tractors are being-touted as a labor-saving innovation. The John Deere 8R fully autonomous tractor is pictured ahead of the Consumer Electronics Show (CES) in Las Vegas, 2022. It features GPS and 360-degree cameras that allow it to be controlled from a smartphone.

Robotics has huge potential when it comes to food production. At the Swiss Federal Institute of Technology Lausanne, Josie Hughes (pictured) is developing a raspberry-picking robot powered by artificial intelligence.
This robot is used to plant seeds and check on plants at the Nordic Harvest vertical farm near Copenhagen, Denmark.

The town of Morehead, Kentucky, is home to the biggest greenhouse in the US. Set across 60 acres and operated by AppHarvest, it uses robotics and artificial intelligence to grow up to 45 million pounds of tomatoes per year. Using 300 sensors, the facility collects data from the plants, and growers can remotely monitor the microclimate to ensure that crops receive the ideal amount of nutrients and water.
Vertical farms grow crops indoors, using LED lights, and without soil. Pictured, AeroFarms' vertical grow towers in Newark, New Jersey.

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.
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.
Insects are increasingly being cultivated as a source of protein. German company Inova Protein farms mealworms, which are processed into animal feed and for human consumption.

Apeel's plant-based food coating can extend the shelf-life of fresh produce.
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.
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.
