Welcome to the September 2021 PEMSEA e-update. PEMSEA would like to share two discussion papers, one on the current status of biofouling management and issues related to invasive aquatic species (IAS) in the East Asian Seas (EAS) region, and one on the current situation and expected future pathways for maritime shipping-related greenhouse gas emissions in East Asia. This month, bilateral meetings were held with the Philippines and Viet Nam for the Blue Solutions project. Please also join us in several East Asian Seas Congress (EASC) collabs on marine protected areas management and climate change adaptation in October. In between newsletters, follow us on Facebook, LinkedIn and Twitter (@PEMSEA) for the latest updates.
