Social-ecological resilience of freshwater systems in lower Mekong basin in southeast Asia is largely unknown. Over the recent past, the freshwater ecosystems in the region have gone through severe environmental stress. Climate change, sea level rise, over-extraction of water and eutrophication together have increased vulnerability to regime shifts of ecosystems in the region. Regime shifts can have long-lasting effects on social-ecological resilience. Response diversity plays a central role in linking ecological, social, and financial systems and enhances resilience. Documenting regime shifts and associated feedbacks as well as the role of response diversity in social-ecological resilience and ecosystem goods and services in the region is essential for future sustainability. In this study, primarily, I have described mechanisms behind emergence of feedback loops at a time of regime shifts and its impacts on ecological resilience. Secondly, I have developed a framework for social-ecological resilience of freshwater ecosystems for southeast Asian region. Thirdly, I have provided current contexts of social-ecological resilience of two of the most productive freshwater ecosystems in the lower Mekong basin of southeast Asia: the Tonle Sap Lake (Cambodia) and the Vietnamese Mekong Delta. Finally, in conclusion, I have outlined the key roles response diversity plays in showing the effects of environmental stress and maintaining social-ecological resilience in the region.

东南亚湄公河流域的淡水系统的社会生态适应力在很大程度上尚不清楚。在最近的过去，该地区的淡水生态系统遭受了严重的环境压力。气候变化，海平面上升，水的过度开采和富营养化共同增加了该区域生态系统制度转变的脆弱性。政权转移会对社会生态适应力产生长期影响。响应多样性在将生态，社会和金融系统联系起来并增强抵御力方面发挥着核心作用。记录制度转变和相关的反馈，以及响应多样性在该地区社会生态适应力和生态系统产品与服务中的作用对于未来的可持续性至关重要。在本研究中，主要是 我已经描述了政权转移时反馈回路出现的背后机制及其对生态适应力的影响。其次，我为东南亚地区的淡水生态系统建立了社会生态适应力框架。第三，我提供了东南亚湄公河下游两个生产力最高的淡水生态系统-洞里萨湖（柬埔寨）和越南湄公河三角洲的社会生态适应力的现状。最后，总而言之，我概述了响应多样性在显示环境压力影响和维持该地区的社会生态适应力方面所起的关键作用。我为东南亚地区的淡水生态系统开发了社会生态适应力框架。第三，我提供了东南亚湄公河下游两个生产力最高的淡水生态系统-洞里萨湖（柬埔寨）和越南湄公河三角洲的社会生态适应力的现状。最后，总而言之，我概述了响应多样性在显示环境压力影响和维持该地区的社会生态适应力方面所起的关键作用。我为东南亚地区的淡水生态系统开发了社会生态适应力框架。第三，我提供了东南亚湄公河下游两个生产力最高的淡水生态系统-洞里萨湖（柬埔寨）和越南湄公河三角洲的社会生态适应力的现状。最后，总而言之，我概述了响应多样性在显示环境压力影响和维持该地区的社会生态适应力方面所起的关键作用。
