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.
KAUST, the National Livestock and Fisheries Development Program (NLFDP), and the National Research and Development Center for Sustainable Agriculture (Estidama) are collaborating to explore algae-based biostimulants for agriculture. These biostimulants, derived from marine algae, enhance plant growth and nutrient uptake without the negative impacts of chemical fertilizers. KAUST already operates a commercial-scale algae manufacturing plant capable of producing tons of algae per month for biostimulant production. Why it matters: This initiative positions Saudi Arabia as a leader in sustainable food technology by leveraging algae biostimulants to improve soil health and reduce dependence on imported raw materials.
KAUST researchers have developed new techniques to produce nutritious microalgae in industrial volumes using seawater-adapted Spirulina and Chlorella strains. This innovation eliminates the need for freshwater, making algae-based livestock feed production sustainable and economically viable. The new Saudi Center for Algal Biotechnology Development and Aquaculture will scale up operations from a 1,000 square meter pilot plant to 42,000 square meters. Why it matters: This could help Saudi Arabia decrease its dependency on imported feed and raw food materials, aligning with its Vision 2030 goals for increased domestic food security.
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.
Al-Maha Systems, a startup founded by KAUST students, has developed an IoT system for livestock health tracking. The system uses sensors attached to cows to monitor vital data like heart rate and body temperature, transmitting it to a cloud server. The goal is to detect health problems early and optimize breeding times for dairy farms. Why it matters: This innovation can improve efficiency and productivity in Saudi Arabia's dairy industry by leveraging IoT for animal husbandry.
