Plant diversity predicts resistance to grazing pressure on drylands

KAUST · Mar 9

A KAUST-led study in *Nature Ecology & Evolution* finds that plant species diversity is the strongest predictor of dryland ecosystem resistance to grazing pressure, outperforming climate and soil factors. Analyzing 73 sites across 25 countries, researchers found that diverse plant communities better maintain vegetation cover under grazing. This is attributed to varied species responses distributing grazing pressure and buffering vegetation loss. Why it matters: The findings highlight the importance of biodiversity in maintaining the productivity and stability of dryland ecosystems, which support half of global livestock production and a billion people's livelihoods.

Global study led by KAUST highlights impact of livestock grazing in arid lands

KAUST · Oct 22

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.
