The UAE imports approximately 85% of its food, making food security a critical national concern. In a country with limited arable land and scarce water resources, traditional agriculture cannot meet domestic demand. To overcome these challenges, the UAE is turning to vertical farming, hydroponics, and high-tech controlled-environment agriculture as scalable, sustainable solutions.
Rethinking agriculture for the desert
High temperatures, saline soil, and minimal rainfall make conventional farming difficult in the Gulf. To address this, vertical farming and hydroponic systems are being deployed, which allow crops to grow in stacked layers or nutrient-rich water rather than soil. These methods drastically reduce land usage and water consumption while enabling farms to be located closer to cities, cutting down transportation needs and ensuring fresher produce.
Hydroponics alone can reduce water use by up to 90% compared to soil-based farming. Vertical farming offers year-round production and reduces the need for pesticides, making it a cleaner, more reliable way to produce food in desert climates.
Big investments, bigger yields
The UAE has made large-scale investments to support this transition. Dubai hosts Emirates Crop One, the world’s largest vertical farm. This $40 million facility produces over 1 million kilograms of leafy greens annually, while using 95% less water than conventional agriculture. Abu Dhabi has allocated $272 millionto support indoor farming start-ups, further accelerating innovation and domestic production capacity.
In 2023, Pure Harvest Smart Farms, a UAE-based agri-tech company, raised over $180 millionto expand climate-controlled farming across the region. These investments position the UAE as a hub for innovation in desert agriculture and signal to global investors that controlled-environment agriculture is a viable, scalable solution.
Beyond leafy greens
While initial focus has been on high-value crops such as lettuce, spinach, and herbs, the UAE is experimenting with other crops like tomatoes, strawberries, and root vegetables. Some farms are exploring aquaponics, which integrates fish farming with hydroponic systems, creating a closed-loop ecosystem where nutrient waste from fish feeds plants. These approaches expand the variety of crops that can be grown sustainably in the desert.
Advanced technologies such as AI and IoT are also being applied to optimise nutrient delivery, water usage, and energy efficiency. Sensors track plant growth and environmental conditions in real-time, allowing farmers to maximise yields while minimising waste. These innovations reduce costs, lower emissions, and generate valuable data to further scale desert farming across the region.
Climate action through food security
Scaling vertical and hydroponic farming is not just about increasing domestic food production. It also significantly contributes to climate action. Local production reduces the need for imported food, lowering transportation-related emissions. It also ensures more resilient supply chains in a region vulnerable to climate shocks, water scarcity, and geopolitical risks.
This strategy aligns with the UAE’s National Food Security Strategy 2051, which aims to place the country among the top 10 most food-secure nations globally by 2051.
Why this matters for CARE
The UAE’s desert farming initiatives demonstrate that sustainability encompasses more than energy or transport solutions. They show how innovation, investment, and technology can transform one of the world’s most challenging climates into a productive agricultural hub.
At CARE 2025 (Climate Action, Renewable Energy & Sustainability Forum), food security is a central theme. From vertical farms and hydroponics to climate-smart agriculture, CARE connects policymakers, investors, and innovators to share insights, explore collaborations, and scale solutions. These developments serve as a blueprint for other arid regions seeking sustainable food production.
If farming can thrive in the desert, it can thrive anywhere.
