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 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 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.
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.
