Researchers at King Abdullah University of Science and Technology (KAUST) have developed a nanostructured solar panel coating designed to maintain performance in dusty, arid environments while capturing atmospheric moisture. Outdoor tests at KAUST over six months demonstrated minimal performance loss on treated panels, contrasting with significant declines in uncoated panels. The coating also condenses water vapor at night, which then rolls off, cleaning the panel and providing collected water sufficient for small-scale irrigation. Why it matters: This innovation offers a sustainable solution for improving solar energy efficiency and providing a supplementary water source in water-scarce regions, addressing critical challenges for renewable energy deployment in the Middle East.
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 HALO group launched a CubeSat in 2023 for high-precision Earth observation in the Gulf region, combining GNSS Reflectometry and hyperspectral sensing. The satellite monitors vegetation, soil, agriculture, and ecosystem health, providing detailed estimates of irrigation water use and vegetation health. The Extreme Statistics (XSTAT) research group at KAUST focuses on the mathematical modeling and prediction of extreme weather and climate events. Why it matters: These KAUST initiatives enhance climate resilience in the region through advanced monitoring, statistical modeling, and predictive capabilities.
KAUST's Center for Desert Agriculture (CDA) and The KAUST School (TKS) hosted the second annual Plant Science Family Night, featuring over 25 interactive stations. The event engaged families from the KAUST community in learning about plant biology and sustainability, covering topics like composting, genetics, and irrigation. Representatives from organizations including CDA, TKS, Terraxy, and KAUST Sustainability participated with demonstrations and discussions. Why it matters: Such outreach events are important for promoting science education and environmental stewardship within Saudi Arabia, inspiring the next generation of scientists and innovators.
KAUST's Sciencetown Episode 25 features Professor Pascal Saikaly discussing novel wastewater treatment approaches at KAUST's Water Desalination and Reuse Center. The episode highlights innovative methods for producing clean water for non-potable uses like irrigation. A recently installed portable pilot plant is designed to provide sanitation for rural Saudi areas with reduced costs. Why it matters: This showcases KAUST's contribution to sustainable water solutions, crucial for water-scarce regions like Saudi Arabia.
Red Sea Farms, a KAUST agriculture technology spinout, placed third at the Entrepreneurship World Cup (EWC) and won $150,000. The startup specializes in saltwater greenhouse technology to reduce the dependence on fresh water for irrigation. Red Sea Farms recently received $1.9 million USD in seed funding from KAUST's Innovation Fund and Research Products Development Company to build a pilot greenhouse. Why it matters: This award and funding will enable Red Sea Farms to scale their production of saltwater tomatoes and address food system sustainability in water-scarce regions.
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 held its third annual Plant Science Family Night on February 19, 2025, hosting over 1,000 attendees from the KAUST community. The event featured 25 interactive stations covering topics like composting, genetics, recycling, and irrigation. Participants included representatives from the Center of Excellence for Sustainable Food Security, the KAUST School, and other organizations. Why it matters: This event promotes STEM education and engagement with sustainability issues among families in the KAUST community.
