"With little water, scorching temperatures, and not much arable land, the UAE currently imports 80% of its food. Can it go local? In an industrial park built off a highway in the arid land between Abu Dhabi and Dubai, a sprawling new indoor farm will soon grow tomatoes under LED lights in a climate-controlled warehouse near a plastic production facility and other factories. The farm, the first in the world to commercially grow tomatoes solely under artificial light, is one part of a push to transform food production in the United Arab Emirates, where 80% of food is imported. The government realizes that to be resilient, it will need to find new ways to grow food in a desert climate with little rain and temperatures that regularly stay above 100 degrees."

"Evaporative coolers have been known to purveyors of low-cost, sustainable technologies for years. Without the need for electricity, these cold containers have kept produce fresh from farms to tables, protecting against post-harvest losses in the field and food spoilage in hot pantries worldwide. Now the concept has been applied to air conditioning. Manoj Patel Design Studio in Vadodara, Gujarat (India) has built evaporative air conditioners that can cool a room for days on a single tank of water. The studio designs new products from recycled materials, and they built their air conditioners from ceramics and stone, integrating them with potted plants. By filling rows of ceramic tubes with water, the prototypes maximize their surface area for optimal evaporation while retaining a small footprint. ..."
