Core Insights - The Qingdao Marine Sargassum Comprehensive Management Project, undertaken by China State Construction Engineering Corporation (CSCEC) No.8 Bureau, has successfully completed its objectives, demonstrating a new paradigm of "technology-driven" management for ecological protection and sustainable urban development in the Yellow Sea region [1][7]. Group 1 - The project has collected a total of 28,000 tons of Sargassum, with a maximum daily processing capacity exceeding 1,700 tons, achieving a 30% increase in harvesting efficiency [1][5]. - A technological governance chain has been established in collaboration with the National Marine Satellite Application Center, moving beyond traditional "interception + harvesting + disposal" methods [3][5]. - The project employs a comprehensive monitoring system that includes high-resolution satellite remote sensing, IoT smart buoys, and drones, creating a closed-loop process of "monitoring - early warning - dispatch" [3][5]. Group 2 - The project has set multiple records in Sargassum management, including the installation of a 44-kilometer interception net in Laoshan District, with a total unloading volume of 51,000 tons and a 30% increase in daily processing compared to traditional methods [5][7]. - A "daily three-check" system is implemented to ensure the quality of operations, focusing on harvesting cleanliness, equipment status, and protective measures, alongside a safety control system [5][7]. - The innovative "sealed transport + resource utilization" model ensures that Sargassum removal is efficient and environmentally friendly, preventing secondary pollution and achieving compliance with water quality standards in the operational sea area [7].

Core Viewpoint - The third United Nations Ocean Conference held in Nice, France, from June 9 to 13, proposed the "Nice Ocean Action Plan" to address global ocean governance issues, particularly focusing on marine biodiversity protection [1][2]. Group 1: Ocean Governance and Biodiversity - The conference addressed critical issues such as overfishing, climate change impacts, and unsustainable resource management [1]. - The "Nice Ocean Action Plan" consists of a political declaration calling for specific actions, including expanding marine protected areas, decarbonizing the shipping industry, addressing ocean pollution, and funding for vulnerable coastal and island regions [1]. - As of June 13, 136 countries, regions, and organizations signed the agreement on the conservation and sustainable use of marine biodiversity in areas beyond national jurisdiction, with 50 already ratifying it, nearing the target of 60 [2]. Group 2: Climate Change and International Cooperation - Ocean governance is deemed crucial for global climate governance, with the ocean carbon sink being 20 times larger than terrestrial carbon sinks and 50 times larger than atmospheric carbon [3]. - The conference highlighted the importance of multilateralism in addressing global challenges such as climate change and rising sea levels, with China being recognized for its contributions to ocean governance [3]. - Participants emphasized the need for international cooperation in protecting the planet, with calls for all nations to collaborate rather than act unilaterally [3].

Core Viewpoint - The third United Nations Ocean Conference, co-hosted by France and Costa Rica, aims to accelerate actions for the protection and sustainable use of oceans, addressing critical challenges such as plastic pollution and overfishing [1][2]. Group 1: Importance of the Ocean - The ocean is a shared resource that provides food, sustainable energy, trade routes, and scientific knowledge, highlighting its significance for humanity [1]. - Current challenges include a lack of global governance frameworks and insufficient funding for ocean protection [1]. Group 2: Multilateral Action - Multilateral action is urgent, as demonstrated by the successful adoption of the Paris Agreement ten years ago, which established a legally binding framework for controlling global warming [2]. - France and China have reaffirmed their commitment to ocean protection through joint statements and cooperation on climate change and biodiversity [2]. Group 3: Key Areas of Focus for the Conference - Improving governance systems is essential, as the absence of regulatory frameworks poses significant risks to marine ecosystems [3]. - Increasing financial investment from both public and private sectors is crucial for supporting sustainable blue economy development [3]. - Enhancing ocean knowledge is necessary, as human understanding of the ocean remains limited despite it covering 70% of the Earth's surface [3].
