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.
The Global Water Monitor Consortium, including KAUST, released its 2023 report, finding that 77 of 249 countries experienced record-high temperatures. Saudi Arabia had its third-hottest year but highest precipitation in 20 years. Vegetation vigor in Saudi Arabia was also the highest since 2001, almost 8% higher than the long-term average. Why it matters: The report highlights climate change impacts in Saudi Arabia, emphasizing the need for accessible information on water resources for stakeholders and the potential for increased vegetation due to higher rainfall.
Dr. John Bedbrook of DiCE Molecules LLC spoke at KAUST about the challenges of feeding a growing population with increasingly stressed arable land. He noted the increasing demand for meat in emerging economies exacerbates the problem. Bedbrook emphasized the role of genetics and hybridization in improving crop yields and quality to address food security. Why it matters: Investments in agricultural biotechnology are crucial for the GCC region to enhance food security and reduce reliance on imports amid changing climate conditions.
KAUST Associate Professor Liming Xiong is researching how plants adapt to drought conditions, focusing on reducing water consumption, increasing water uptake, and surviving under stress. His "whole plant" approach aims to identify major genes controlling water uptake, water loss, and cellular detoxification. The research seeks to develop plants that use water more efficiently or can be irrigated with brackish water, important for agriculture in Saudi Arabia. Why it matters: Understanding the molecular mechanisms of plant drought tolerance can help in breeding stress-tolerant crops suitable for the arid conditions in the region.
KAUST's Center for Desert Agriculture is holding an international conference on November 3-5, 2014, focusing on desert rhizosphere microbes for sustainable agriculture. Researchers aim to understand how plants survive in extreme conditions by studying microbes that help them tolerate heat, drought, and salt. They will explore genetic engineering and natural microbe usage to improve crop performance under heightened stress conditions. Why it matters: This research is critical for adapting agricultural systems to global warming and meeting future food production challenges in arid regions like the Middle East.
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 researchers found a 25-30% increase in winter rainfall in the eastern Arabian Peninsula since 1981, with a 10-20% decrease in the south and northeast. This change correlates with a shifting El Niño pattern in the tropical Pacific Ocean, affecting sea surface temperatures and westerly winds. The study used rainfall data from the University of East Anglia and 39 stations across the peninsula from 1951-2010. Why it matters: Improved understanding of these climate drivers could enhance long-term rainfall predictions, benefiting agriculture and water resource management in this arid region.
The Directed Energy Research Center (DERC) received a US$1.5 million grant from the UAE Research Program for Rain Enhancement Science (UAEREP). The grant was awarded at the UAEREP's 5th Cycle Awarding Ceremony in Abu Dhabi. DERC was recognized for its research on laser-induced rain and the development of a mobile high-power pulsed laser using remote sensing. Why it matters: This funding supports the development of sustainable, chemical-free rain enhancement technologies, addressing critical water security challenges in arid regions.
