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 Hydrology and Land Observation (Halo) lab, led by Matthew McCabe, is using drones and satellites to monitor agricultural water usage in Saudi Arabia. They employ thermal cameras, sensors, and imagery from CubeSats to map crop types, health, and water stress. The team uses machine learning and AI to analyze the images, aiming to promote sustainable water management. Why it matters: This research addresses critical water scarcity issues in the region by providing data-driven insights for more efficient agricultural practices.
KAUST researchers are addressing the challenge of growing electricity consumption in cooling technologies, as the global demand for air conditioning increases by 3-4% annually. In Saudi Arabia, cooling systems account for up to 70% of electricity usage during the summer. Researchers at KAUST's Water Desalination and Reuse Center are exploring ways to improve the energy efficiency of chillers to reduce costs and CO2 emissions. Why it matters: Improving cooling efficiency is critical for reducing energy consumption and carbon emissions, especially in hot climates like Saudi Arabia and other GCC countries.
KAUST researchers are developing innovative solutions for water treatment and desalination in Saudi Arabia. A pilot anaerobic membrane bioreactor in Jeddah treats 50,000 liters of wastewater daily at zero energy cost, producing water suitable for reuse and liquid fertilizer. Another KAUST team focuses on advancing desalination technologies by integrating renewable energy and reducing energy consumption and brine discharge. Why it matters: These advancements can significantly contribute to Saudi Arabia's water security and sustainability goals by reducing reliance on non-renewable groundwater and fossil fuels for desalination.
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's Water Desalination and Reuse Research Center (WDRC) is dedicated to reducing the energy footprint of desalination, with Saudi Arabia being the largest producer of desalinated water globally. Biofouling, caused by organisms like the bay barnacle, increases the energy required for desalination and affects various sectors, including medical devices and marine vessels. Researchers at WDRC, including Professor Matthew McCabe and Director Johannes Vrouwenvelder, are exploring novel desalination technologies and anti-fouling agents to combat biofouling. Why it matters: Addressing biofouling is crucial for reducing the economic and ecological costs of desalination in water-scarce regions like Saudi Arabia and improving efficiency across multiple industries.
Researchers developed a two-stage AI pipeline to predict desalination performance efficiency losses due to climate factors in the UAE, achieving 98% accuracy. The model forecasts aerosol optical depth (AOD) and uses it to predict desalination efficiency, incorporating meteorological data. A dust-aware control logic was developed to optimize plant operations, and an interactive dashboard was created for decision support.
KAUST researchers are developing new solar desalination methods to increase efficiency and minimize heat losses, building on techniques dating back to Arab alchemists. KAUST Associate Professor Peng Wang and his team at the Water Desalination and Reuse Center are developing an innovative system that more efficiently vaporizes water using interfacial heating. The design uses a photothermal material to capture the entire spectrum of sunlight and convert it into heat with nearly 100% efficiency. Why it matters: This research could provide more sustainable and efficient methods for producing fresh water in arid regions like the Middle East.
