Limnogeologists and paleolimnologists investigate ancient to recent lakes, either from geological archives preserved in sedimentary basins, or from sediment cores collected from the bottom of lakes. We all come from different disciplines (sedimentology, biology, geochemistry, geophysics, geomorphology, paleontology, archeology, …) and analyse a great diversity of archives (exposures, cores, multibeam bathymetric maps, seismic profiles, landforms, …) in order to reconstruct the story of past lacustrine geo-eco-systems, and to reveal the various factors that have driven their evolution over time, often with annual-seasonal resolution.
This session examines how we can transfer our tremendous knowledge about the evolution of lakes in the past, to realistically imagine and anticipate the near future of lakes? The ongoing climate change and the growing demand on natural resources has already started to impact continental hydrosystems (rivers, lakes, and wetlands), and this is likely to increase in the next few decades, leading to significant water-level changes for many lakes around the world. As such, the near future of lakes, firstly terminal lakes but ultimately all lakes, sounds rather uncertain.
We welcome all contributions concerning past and present lakes, and orientated toward a better understanding of future evolution of lakes (water balance, sediment budget, algal blooms, hydrodynamics, shoreline trajectory, coastal erosion, storm surges, water quality, …) and their consequences on social-ecological systems (biodiversity and human activities). All abstracts submitted should include a reflection of the main results towards the future development of lakes.
