Summary: This study provides global predictions of seaweed habitat productivity, using data from over 400 sites and finding a strong correlation between seaweed productivity and climatic variables. Seaweed forests exhibit exceptionally high per-area production rates, being more than 10 times higher than coastal phytoplankton.

Summary: Agricultural expansion is a major cause of climate change and biodiversity loss. Seaweed farming in the ocean could reduce the demand for terrestrial crops and greenhouse gas emissions from agriculture. By modeling the global potential of seaweed farming, this study explores how increased seaweed utilization could affect the environmental footprint of agriculture. Results show that a large area of the ocean has the potential to support seaweed farms, and cultivating Asparagopsis for ruminant feed could have the highest greenhouse gas mitigation.

Summary: Seaweed aquaculture, accounting for over half of global mariculture production, provides various ecosystem services and food/natural products for industries. It is seen as a versatile solution for climate change and biodiversity crisis. Scaling up seaweed aquaculture as an emission capture and utilization technology is crucial to support a circular bioeconomy and achieve UN Sustainable Development Goals for a growing global population by 2050.

Summary: This study demonstrated the significant impact of seaweed extract in increasing wine grape yield by an average of 14.7% across multiple growing years, with varying effects depending on grape cultivars. The findings suggest that soil-applied seaweed extract can be a profitable strategy for enhancing wine grape production in Australian viticulture.

Summary: With the increase in world population and global climate changes, ensuring adequate food supply is crucial. This review explores the potential of red seaweed proteins as an alternative protein source and discusses their applications in food and nutraceutical industries, environmental impact, affordability, and safety concerns. The findings suggest that red seaweed proteins have potential as sustainable alternatives to terrestrial proteins, but further research is needed to improve their extraction and enhance their functionalities for various applications.

Summary: The European seaweed sector is transitioning from harvesting wild stocks to harvesting and farming seaweed, necessitating a rethinking of its role on a global scale and the need for insight into the global seaweed value chain organization and innovation. Innovation in seaweed usage is occurring globally, with a focus on high-value applications not being enough to distinguish the nascent European sector from established regions such as Asia. Stronger collaboration and joint efforts are needed in developing safe and sustainable products to meet regulatory, lead firm, and consumer demands in order to facilitate further business development.

Summary: Upwelling systems deliver nutrient-rich water into coastal ecosystems, influencing primary productivity and potentially altering seaweed-herbivore interactions. This study compares the physical-chemical characteristics and nutrient levels in upwelling and downwelling zones, and investigates their influence on seaweed biomolecules, algae-herbivore interactions, and the growth of sea urchins. The results show that upwelling zones have lower temperatures, lower pH, and higher phosphate concentrations, and seaweeds from upwelling zones have higher protein and carbohydrate content compared to downwelling zones. Sea urchins from upwelling zones consume and grow more than those from downwelling zones. The availability and quality of food in upwelling zones have an influence on herbivore-seaweed interactions.

Summary: In this paper, we analyze the relationship between technological innovation in the artificial intelligence (AI) domain and macroeconomic productivity. Our estimates provide evidence in favor of the modern productivity paradox, showing that the development of AI technologies has a negligible role in the officially recorded productivity growth process. This result is robust to changes in the country sample, labor productivity quantification, empirical model specification, and estimation methods.

Summary: High-resolution satellite observations are essential for monitoring global progress towards Sustainable Development Goals. The study shows that global cropland area increased by 9% in the first two decades of the twenty-first century, while per-capita cropland area decreased by 10%. This was primarily due to agricultural expansion in Africa and South America, leading to conflicts with the goal of protecting terrestrial ecosystems. Despite a decrease in per-capita cropland area, per-capita annual cropland net primary production increased by 3.5% due to intensified agricultural land use.

Summary: A global analysis shows that tree species diversity promotes drought resistance in nearly half of global forests. The impact of species diversity on resistance varies across regions, with larger benefits observed in dry and drought-prone forests. Restoring species diversity could be an effective strategy to mitigate the impact of extreme droughts, especially in dry regions.

Summary: This study uses large-scale panel data of Indian manufacturing firms at the firm-product level to examine the relationship between global value chain participation and firm performance. The findings indicate that firms participating in the global value chain experience a productivity premium and a decrease in markups, primarily due to rising costs associated with imported intermediate inputs.
