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.
A KAUST-led study in Nature proposes reversing land degradation by 2050 through increased sustainable seafood production, reduced food waste, and land restoration. The study suggests straightforward measures like modifying economic incentives and promoting sustainable aquaculture policies. Researchers estimate these policies could save a land area roughly the size of Africa. Why it matters: The KAUST-led research offers a tangible blueprint for addressing critical food security challenges in arid regions like Saudi Arabia and globally.
KAUST researchers, in collaboration with Aeon Collective, have issued a call for global leaders to prioritize land restoration and food systems. Their policy paper, launched at COP16 in Riyadh, outlines a framework for halving degraded land by 2050. The initiative aims to reverse the negative impacts of land degradation, including increased food insecurity and exacerbated climate change. Why it matters: The focus on land restoration at a major UN conference hosted in the Middle East highlights the region's growing role in global sustainability efforts and the importance of addressing desertification.
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 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'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.
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.
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.
