Congress of the International Society of Limnology

Nanjing, China
Working groups
Meeting Category

The Congress of the International Society of Limnology (SIL 2018) will be held in Nanjing, China, from the 19-24 August 2018.


Freshwater ecosystems are increasingly threatened by human activity and the effects of climate change. The global response to these challenges has been mixed. In the developed world, the issue of eutrophication of inland waters has been a matter of intense focus and some remarkable counter measures, whilst in developing countries the situation has continued to worsen, as seen in the increasingly frequent and severe cyanobacterial blooms in Lake Taihu, China.

The urgent demand for knowledge and techniques for the management and restoration of aquatic ecosystems is reflected in the theme of SIL 2018, "Limnology, a Science for the Preservation and Restoration of Aquatic Ecosystems".

Session S13: Long term dynamics of lake social-ecological system in past, present and future
Co-chairs: Ke Zhang, John Dearing, Giri Kattel and Fabien Arnaud

Globally, many lakes have been rapidly degrading. The cumulative effects of multiple drivers acting together synergistically on lake ecosystems have caused substantial change ecosystem functions and functions, which have direct impacts on people’s livelihoods and well-being. Dealing with this grand challenges needs a rigorous understanding of complex interactions between human and natural systems. Of particular concern is nonlinear dynamics of ecosystem change, which are hard to predict and are often costly for management, most probably impossible to reverse if the threshold were crossed. The mounting concerns about potential regime shifts from local to global scale and a better understanding of potential risks and consequences of such shifts have been identified as an urgent priority among scientists, stakeholders and policymakers.
How the functioning of freshwater lake ecosystems and services is maintained while they are kept within safe operating space without being crossed the tipping point needs to be debated extensively. This requires not only evidence and perspective about nonlinear dynamics, but also new and evolving scientific approaches to increase lake system resilience. Enhanced understanding of the long-term interactions between human actions, climate and the functioning of lake social-ecological system is critical to obtain desirable and safe future.
This special session aims to achieve improved knowledge and understanding of complex interactions of the social and ecological system, examining resilience, thresholds and critical transition in lakes over the past, present and future. This special session will bring experts from both natural and social sciences to discuss new ideas, theoretical advancement, and approaches being used for lake social-ecological system resilience research, and to identify the key challenges in this area.
