大河三角洲是连接流域与海洋的关键枢纽，是人类文明的重要发源地、全球人口和经济活动高度集聚区，也是实现联合国可持续发展目标的重要战略区域。全球主要大河三角洲依托广阔流域提供的水资源、泥沙和营养物质，以及邻近海岸带和近海生态系统提供的生态服务，支撑着区域经济发展、粮食安全、生态安全和社会福祉。然而，在气候变化和人类活动共同影响下，流域开发利用、水资源调控、引水筑坝、土地利用变化和污染物排放等过程正在深刻改变河流输沙格局和陆海物质循环；与此同时，海平面上升、极端天气事件增多、海岸侵蚀和生态系统退化等问题日益突出，对三角洲稳定性、海岸带生态安全以及近海环境健康构成严峻挑战。面对这些跨区域、跨系统的复杂问题，亟需加强流域、三角洲与海岸带不同利益相关方之间的交流合作，推动陆海统筹治理和科学决策，共同探索人与自然和谐共生的可持续发展路径。
联合国“海洋科学促进可持续发展十年（2021–2030）”倡导通过科学创新支撑海洋可持续发展，其中“大河三角洲（Mega Delta）”计划致力于推动全球大河三角洲地区在气候变化适应、生态系统保护、风险防控和可持续发展方面的国际合作与知识共享。与此同时，联合国“科学促进可持续发展国际十年（2024–2033）”框架下的“陆海对话：海岸带可持续发展方案（CROSS Coastz）”计划，强调以系统科学为基础，促进河口、海岸带与近海复杂系统的协同治理，推动科学界、政府部门、企业和社会公众共同参与解决可持续发展挑战。
在上述国际倡议框架下，第五届大河三角洲国际会议暨海岸带可持续发展国际研讨会将汇聚来自全球不同流域、河口三角洲和海岸带地区的科学家、管理者、企业界代表及国际组织成员，围绕流域—河口—海岸带耦合系统面临的环境变化与发展挑战，分享前沿科学成果、治理经验和创新实践，共同探索面向未来的可持续发展解决方案，为落实联合国可持续发展目标和构建人与自然和谐共生的海洋命运共同体贡献智慧。

The 5th UN Ocean Decade Conference on Mega Deltas & the UN International Decade of Sciences Conference on Coastal Sustainability
October 18–21, 2026 · Shanghai, China
Mega deltas are critical interfaces linking river basins and the ocean. They are cradles of human civilization, centers of population and economic activity, and strategic regions for achieving the United Nations Sustainable Development Goals. Sustained by freshwater, sediment, and nutrient inputs from vast river basins, as well as ecosystem services provided by adjacent coastal and marine environments, mega deltas support regional economic development, food security, ecological security, and human well-being. However, climate change and human activities are increasingly altering river discharge, sediment transport, and land–sea material exchanges through water regulation, dam construction, land-use change, and pollution. At the same time, sea-level rise, more frequent extreme events, coastal erosion, and ecosystem degradation pose growing threats to delta stability, coastal resilience, and nearshore environmental health. Addressing these interconnected challenges requires stronger collaboration among stakeholders across river basins, deltas, and coastal zones, and the development of integrated land–sea governance approaches for sustainable development.
The United Nations Decade of Ocean Science for Sustainable Development (2021–2030) promotes science-based solutions for a sustainable ocean. Within this framework, the Mega Deltas Programme advances international cooperation, knowledge sharing, and innovation for climate adaptation, ecosystem conservation, risk reduction, and sustainable development in major delta regions worldwide. In parallel, the United Nations International Decade of Sciences for Sustainable Development (2024–2033) supports the Land–Sea Dialogue for Coastal Sustainability (CROSS-Coasts) programme, which emphasizes systems-based approaches to strengthen coordination among estuaries, coastal zones, and adjacent marine ecosystems, while engaging scientists, policymakers, businesses, and society in addressing sustainability challenges.
Under these international initiatives, the 5th International Conference on Mega Deltas and Coastal Sustainability will bring together scientists, policymakers, practitioners, business leaders, and representatives of international organizations from river basins, deltas, and coastal regions worldwide. Participants will share scientific advances, governance experiences, and innovative practices related to environmental change and sustainable development in coupled river basin–delta–coastal systems, and explore solutions that contribute to the achievement of the Sustainable Development Goals.
