A KAUST-led study across 25 countries found livestock management as critical as climate in explaining woody species coverage in arid zones. The BIODESERT research network analyzed livestock management, fire, climate, and soil, finding that grazing pressure and herbivore type significantly impact arid ecosystems. Researchers are identifying conditions where grazing pressure can be optimized for sustainable production. Why it matters: The findings enable targeted interventions through livestock management and policies, offering localized solutions for sustainable production in arid regions crucial for 2 billion people.
KAUST researchers are contributing new information about desert and mangrove plants to support Saudi Arabia's Green Initiative. They are creating a soil atlas for Saudi Arabia, studying soil profiles and microbial populations in hyperarid regions. The team has also compiled the world’s largest biobank of desert microbes, sequencing each microbe's genome. Why it matters: This research is crucial for ensuring the success and sustainability of large-scale greening efforts in arid environments like Saudi Arabia.
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.
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 researchers are using CarboSoil biochar and native biocrusts to revitalize arid lands in Saudi Arabia, enhancing soil fertility, capturing carbon, and reducing erosion. CarboSoil, engineered from poultry waste by KAUST's Himanshu Mishra, improves nutrient and water retention in desert soils. Terraxy, Mishra's startup, aims to convert all of Saudi Arabia's poultry waste into CarboSoil, supporting greening initiatives. Why it matters: This technology offers a sustainable solution to boost domestic food production, combat desertification, and reduce landfill waste in Saudi Arabia, aligning with the Kingdom's food security and environmental goals.
KAUST has inaugurated the Center for Desert Agriculture (CDA) to focus on research and real-world solutions for local, regional, and global agriculture. Professor Rod Wing will lead the CDA, focusing on crop plant variation, while Professor Mark Tester will serve as associate director, continuing his work on salt tolerance in crops. Other professors, such as Salim Al-Babili and Heribert Hirt, will continue their research into areas including combating parasitic weeds and global food security. Why it matters: The center's focus on desert agriculture and food security addresses critical regional and global imperatives, aligning with Saudi Arabia's broader goals of sustainable development and innovation in food production.
A KAUST-led study reveals unexpectedly high functional diversity in arid and grazed dryland plants globally, examining traits like mineral element concentration in over 300 species across six continents. The research indicates that plants employ diverse adaptation strategies to aridity and grazing, with trait diversity increasing beyond a certain aridity threshold. More than half of the trait diversity was found in the most arid and grazed drylands, challenging the view that harsh conditions reduce plant diversity. Why it matters: This study highlights the ecological value of drylands and suggests plants possess unappreciated resilience to climate change, with implications for conservation and greening programs in regions like Saudi Arabia.
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.
