Globally, landscapes are starting to dynamically respond to human-accelerated climate change hazards. Whilst in the past it was often possible to use geotechnical solutions to control natural landscape dynamics, such as using nature-based or engineered solutions to control river morphology, reduce coastal erosion and flood risks and reduce landslide hazards, these methods are increasingly unviable. As climate change impacts accelerate there will be growing economic, social or physical limits to continued use of ever more expensive geotechnical solutions. Managing many of our landscapes using geotechnical solutions will achieve hard adaptation limits. This session welcomes papers that explore the potentialities of hard physical adaptation limits and the impacts of these for our societies which are built assuming a relatively ‘fixed’ landscape. We welcome papers that can demonstrate how many nature-based solutions work against rather than with natural landscape responses to environmental factors such as sea level rise, increased river flows (leading to avulsions), increased rainfall triggering landslides more frequently and/or drought conditions driving more widespread wildfires reducing landscape stability. Papers exploring some of the wicked problems that arise from increasingly dynamic landscapes, including release of wastes, graves and buildings into the landscape are also sought.
