A study co-authored by KAUST researchers and published in Science analyzes the intertwined climate and biodiversity crises, noting that human activities have altered roughly 75% of land and 66% of marine waters. Greenhouse-gas emissions amount to over 55 gigatonnes of carbon dioxide equivalent per year, with global mean temperature increased by over 1.1 degrees Celsius since the preindustrial era. The study proposes an ambitious approach including emissions reduction, restoration, and cross-institutional alliances. Why it matters: This highlights KAUST's contribution to global research on pressing environmental challenges and informs strategies for regional sustainable development initiatives.
KAUST Professor Carlos Duarte presented a lecture on the rebound of global ecosystems following decreased human activity during the COVID-19 pandemic. Duarte, a member of the Rapid Research Response Team (R3T), discussed evidence indicating the environment's capacity for recovery. He related these findings to the potential for positive change in addressing climate change. Why it matters: The lecture highlights KAUST's contribution to understanding the impact of human activity on ecosystems and potential solutions to climate change.
A KAUST-led international study published in Nature outlines a roadmap for marine life to recover to full abundance by 2050. The study identifies "recovery wedges" consisting of six complementary interventions: protecting species, harvesting wisely, protecting spaces, restoring habitats, reducing pollution, and mitigating climate change. Researchers found evidence of marine life's resilience and a shift from losses to recovery in some areas. Why it matters: The study provides actionable recommendations for large-scale interventions to achieve a sustainable future for marine ecosystems in the Red Sea and globally.
A KAUST-led team used acoustic technology and net sampling to explore ocean depths in 146 locations worldwide. They found that the biomass of pelagic organisms in the deep sea is much larger than previously thought, especially below productive waters. Deep-sea fauna migrates to shallower areas to feed, transporting carbon to the deep sea. Why it matters: This suggests the ocean's carbon pump is more effective than previously understood, with implications for climate change mitigation strategies.
A KAUST-led research team used acoustic readings to reassess fish populations in the ocean's mesopelagic zone (200-1000m depth). Published in Nature Communications, their findings indicate that mesopelagic fish quantities may be ten times greater than current estimates. The study also suggests that open-ocean ecosystems are as efficient as coastal regions in nutrient cycling. Why it matters: This discovery assigns mesopelagic fish a potentially significant, previously unrecognized role in the global carbon cycle and highlights KAUST's contribution to marine science.
An international team including KAUST researchers tracked nearly 2,000 sharks using satellite tags to map their movement and space use. The study found that 24% of shark habitats overlap with pelagic longline fisheries, with higher overlap for commercially exploited species. For North Atlantic blue and shortfin mako sharks, the overlap was 76% and 62% respectively. Why it matters: This research highlights the vulnerability of sharks to industrial fishing and underscores the need for targeted conservation efforts in critical habitats.
KAUST scientists and international researchers published a paper in Frontiers in Marine Science detailing marine spatial planning for Saudi's Red Sea Project. The study, involving The Red Sea Development Company (TRSDC), used spatial planning to achieve net positive conservation outcomes for the Al Wajh lagoon. The research targets a net conservation benefit of 30 percent exceeding typical levels. Why it matters: The study demonstrates that coastal development can enhance conservation through careful design, challenging the traditional view of development versus conservation.
KAUST researchers are developing an AI tool to classify fish species based on economic value and population growth rate, aiming to aid sustainable fisheries management in Saudi Arabia. The tool will help identify species at risk of decline, supporting marine conservation and food security goals outlined in Saudi Vision 2030. Saudi Arabia aims to increase self-sufficiency in seafood production amid declining Red Sea fish populations. Why it matters: This initiative could significantly improve fisheries management and conservation efforts in the Red Sea, informing policy decisions and supporting sustainable food production in line with national objectives.
