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'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 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.
Red Sea Farms, a KAUST spinout specializing in saltwater greenhouse technology, secured $1.9 million in co-investment from the KAUST Innovation Fund and Research Products Development Company (RPDC). Their system uses saltwater to grow crops, reducing freshwater and energy requirements up to tenfold. The investment will enable the company to build a 2,000 square meter saltwater greenhouse on the KAUST campus, with a goal of producing 50 tons of tomatoes annually by 2020. Why it matters: This investment supports sustainable agriculture innovation in the water-scarce Middle East, offering a model for reducing the environmental impact of food production.
