KAUST researchers led by Mark Tester are developing new irrigation technology to enable crop production using semi-saline water, aiming to reduce freshwater reliance to 10% in greenhouse systems. The technology is eco-friendly and intends to cut agricultural costs by utilizing seawater, targeting a cost of 10 U.S. cents per cubic meter. A new company named Red Sea Farms is being developed to grow salt-tolerant tomatoes in diluted seawater in a greenhouse cooled with undiluted seawater. Why it matters: This research could significantly reduce pressure on freshwater resources in arid regions and offers a sustainable approach to increase food production using available seawater.
KAUST researchers are partnering with Saudi farmers and the Ministry of Environment, Water and Agriculture (MEWA) to develop tailored desalination solutions for agriculture. A new KAUST Center of Excellence project aims to integrate controlled environment agriculture (CEA) with desalination of non-conventional water resources for hydroponic farming. The approach focuses on selective ion removal to provide 'clean-enough' water, reducing energy use and costs compared to traditional desalination. Why it matters: This initiative could enable more sustainable and affordable local crop production in Saudi Arabia, potentially shifting the Kingdom from importing to exporting agricultural technologies.
Red Sea Farms, a KAUST startup, is advancing its saltwater greenhouse technology with a new 21,000 square foot pilot facility at the KAUST Research & Technology Park. Their greenhouse technology allows for growing crops on marginal land, using 90% less freshwater than traditional methods. The system uses saltwater in greenhouse-cooling and climate control, resulting in a lower environmental footprint. Why it matters: This technology addresses critical food and water security challenges in arid regions by enabling local food production with minimal freshwater resources and reduced energy consumption.
A KAUST and King Abdulaziz University research team is using superhydrophobic sand to grow crops like tomatoes with less water. Superhydrophobic sand reduces water consumption in agriculture, the world's largest consumer of freshwater. The sand was developed by KAUST's Himanshu Mishra and Ph.D. student Adair Gallo Junior. Why it matters: This research offers a promising solution for water conservation in agriculture, especially in arid regions like the Arabian Peninsula, addressing critical water security challenges.
KAUST's Salt Lab, led by Professor Mark Tester, is researching how salt-tolerant plants survive in harsh environments. The lab aims to improve plant yields in suboptimal conditions, focusing on naturally occurring variability in plants to enhance salinity tolerance. With 70% of global water used for agriculture and increasing water scarcity, the research seeks to unlock the potential of seawater for irrigation. Why it matters: Enhancing the salinity tolerance of crops is crucial for addressing food security challenges exacerbated by climate change and the growing global population, particularly in arid regions like the Middle East.
KAUST is leading a $3.5 million investment in Natufia, an Estonian startup that developed a smart indoor kitchen garden, with $2 million awarded through the KAUST Innovation Fund. Natufia's hydroponic technology allows year-round harvesting of herbs, greens, and vegetables at home, regardless of climate. By taking up residency at the KAUST Research and Technology Park, Natufia aims to expand R&D capabilities and create job opportunities in Saudi Arabia. Why it matters: This investment addresses the challenge of accessing fresh produce in regions like Saudi Arabia while reducing food waste and promoting sustainable agriculture through innovative technology.
KAUST, the National Livestock and Fisheries Development Program (NLFDP), and the National Research and Development Center for Sustainable Agriculture (Estidama) are collaborating to explore algae-based biostimulants for agriculture. These biostimulants, derived from marine algae, enhance plant growth and nutrient uptake without the negative impacts of chemical fertilizers. KAUST already operates a commercial-scale algae manufacturing plant capable of producing tons of algae per month for biostimulant production. Why it matters: This initiative positions Saudi Arabia as a leader in sustainable food technology by leveraging algae biostimulants to improve soil health and reduce dependence on imported raw materials.
KAUST researchers have developed a hybrid cooling technology combining nanotech plastic and biodegradable mulch that significantly enhances crop yields in arid regions. The technology lowers greenhouse temperatures by 25 degrees Celsius and doubles crop yields in tests with Chinese cabbage. The nanotech plastic coating absorbs infrared light, while the biodegradable mulch reflects sunlight to keep the soil cooler. Why it matters: This innovation promises to improve food security in arid regions like Saudi Arabia while reducing energy consumption and plastic waste associated with traditional greenhouse cooling methods.
