A Heritage Commission and KAUST collaboration published in Nature Communications reveals the discovery of large-scale rock art panels in the Nefud Desert, dating back 12,000 years. Over 60 panels with 176 engravings were found depicting animals like camels and ibex. Paleoenvironmental analysis indicates surface water was present 14,000 years ago, supporting early human and wildlife expansion. Why it matters: The findings revise the timeline of human repopulation in Saudi Arabia's interior deserts after the Last Glacial Maximum and demonstrate the significance of interdisciplinary research in understanding the region's climate history.
KAUST and international collaborators discovered that the Rub’ Al-Khali desert was once a vast lake and river system that supported grasslands and savannahs. The "Green Arabia" period, marked by heavy rainfall, facilitated the growth of a lake covering 1,100 km² with a depth of 42 meters, which overflowed and carved a 150 km valley. The research, published in Communications Earth & Environment, highlights the impact of climate cycles on landscapes and human societies. Why it matters: Understanding the past climate transformations in the Arabian Peninsula is crucial for predicting the consequences of current climate change and its impact on regional habitability.
KAUST researchers discovered that dust from the Middle East has a cooling effect over land and the Red Sea. Satellite data indicates dust concentration over the Red Sea is greater than over land, causing significant radiative cooling. The study, published in the Journal of Geographical Research, highlights the climatological dust radiative forcing over the southern Red Sea as the largest globally. Why it matters: Understanding the impact of regional dust on climate change and the Red Sea's ecosystem is crucial for environmental strategies in the Middle East.
A group of KAUST students visited the National Wildlife Research Center (NWRC) in Taif as part of the University's 2015 Winter Enrichment Program. The NWRC, established in 1986, focuses on preserving and reintroducing species like the houbara bustard, Arabian oryx, red-necked ostrich, and Arabian leopard. Researchers at the center track released bustards via radio transmitters, collaborating internationally to preserve their habitats. Why it matters: This highlights Saudi Arabia's commitment to wildlife conservation and international collaboration in ecological research, showcasing KAUST's engagement with regional environmental initiatives.
The National Center for Vegetation Cover Development and Combating Desertification (NCVC) and KAUST have launched the SAUDINet initiative. The initiative aims to advance terrestrial ecology research in Saudi Arabia, focusing on restoring degraded lands, enhancing carbon sequestration and preserving biodiversity. NCVC’s workforce will receive specialized training in biodiversity monitoring and ecological sampling, with samples analyzed in KAUST’s labs. Why it matters: The partnership aims to establish Saudi Arabia as a global leader in the study of arid ecosystems and address the lack of data from hyper-arid lands in climate models.
KAUST's New Energy Oasis (NEO) hosted an open day on May 7 to showcase its renewable energy technologies. The event featured guided tours of the NEO site, where 11 international technology providers are testing renewable energy solutions. The technologies on display included photovoltaic (PV), concentrating solar power (CSP), and dust mitigation technologies. Why it matters: This initiative helps identify and implement the most appropriate renewable energy technologies for Saudi Arabia, addressing the Kingdom's growing energy demands.
A KAUST-led study identified 15 large mammal species that inhabited the Arabian Peninsula in the last 10,000 years, tripling previous estimates. Researchers analyzed thousands of petroglyphs from scientific expeditions, publications, and social media. The study identified two species never known to live in the region before: the greater kudu and the Somali wild ass. Why it matters: The findings provide a benchmark for rewilding efforts and inform decisions on which mammals to reintroduce to the region.
KAUST researchers have found that dust clouds in the Arabian Peninsula are three times larger than previously estimated by current models. The study, published in the Journal of Geophysical Research: Atmospheres, uses refined mathematical models and data collected since 2012 to analyze the impact of coarse dust particles. The updated model indicates that larger particles contribute to over 80% of dust mass on land, leading to significant efficiency loss for solar technology, estimated at 15-45% depending on location. Why it matters: Accurate dust modeling is crucial for the strategic deployment and maintenance of solar technology, supporting Saudi Arabia's sustainable economy goals.
