The presentation will focus on the Global Seaweed New and Emerging Markets Report which was recently published by the World bank. The study was funded by the PROBLUE Multi-Donor Trust Fund under the AquaInvest Platform. It presents new and emerging applications for seaweed-based products, and seeks to identify gaps, innovations, and new opportunities to scale up the seaweed industry and alleviate poverty while improving global environmental resilience. Some of the most promising applications identified in the report are biostimulants, bioplastics, methane reducing feed additives, animal and pet food, construction materials, alternative proteins, nutraceuticals, and pharmaceuticals products. The valorization of ecosystem services provided by seaweed farming activities, including restorative activities, biodiversity conservation and climate change action, is discussed pointing out the potential for seaweed to contribute towards reduction in carbon footprints in food systems. The presentation will showcase the benefits of upscaling of seaweed production towards eradicating poverty while fostering a livable planet for now and future generations.
