Session 7.9: Impacts of global environmental change on freshwater biodiversity

Global freshwater biodiversity is declining at an alarming rate, even higher than observed for terrestrial and marine biodiversity. Freshwater ecosystems are not only subject to local pressures resulting from the vicinity to densely populated areas and upstream-catchment developments, but also suffer from global hydrologic alterations. In large-scale environmental assessments, however, impacts on freshwater biodiversity are often under-represented. In this session we want to explore possible ways forward to better quantify impacts of global environmental change on freshwater biodiversity. To that end, we bring together method developers as well as practitioners to present various areas of methods development and discuss how these may benefit from each other. Examples include remote sensing or ‘big data’ analytics for revealing hydro-ecological relationships, correlative as well as process-based modelling approaches for quantifying environmental impacts on freshwater ecosystems stemming from land use and hydrologic disturbance (water abstraction, hydropower generation, nutrients, toxicants, plastics), and methods that enable to calculate freshwater biodiversity ‘footprints’ of consumers or products.
