I Advancing freshwater biodiversity trend research | Glaspavillon

Chair: Sonja Jähnig – IGB, Berlin (DE)

 

Workshop content: Based on the Living Water Research Agenda (Jähnig et al. 2019) and other recent publications (e.g. Maasri et al. 2022, Harper et al. 2021), this workshop will extent the “Biodiversity trends” session of the conference and explore funding needs and options for larger coordinated activities related to this topic. Discussions will address the most important gaps to fill, e.g. with respect to methodological aspects, spatial and temporal scales in driver and response variables as well as to improving predictions of changes. We will also reflect on mobilisation and digitalisation of biodiversity data. Further details will be provided to participants prior to the workshop.

 

II Changing baselines | Library Hall

Chair: Mario Sommerhäuser – EGLV, Essen (DE)

 

Climate change has far-reaching consequences for water bodies: an increase in extreme hydrological events, warming of surface waters and the associated physical, chemical and biocenotic changes. These are obviously irreversible, are the so-called "New Normal". But if "Mediterranean conditions" occur in large parts of Germany, the question arises how to deal with our previous references, guiding principles and objectives. Are we still pursuing achievable goals, are we implementing the right measures, do they perhaps need to be intensified? Which ones pay off in terms of increasing the resilience of our water bodies? Are renaturation and disconnection of sealed areas 'no regret' measures? How can research support politicians, authorities and water management with objective, goal-oriented answers? The workshop will explore these questions and possibly develop the basis for a joint positioning on these challenges.

 

III Chemical & ecological water quality water quantity | R12 R00 B02

Chair: Martina Flörke – Ruhr University of Bochum (DE) & Peter Krebs – TU Dresden (DE)

 

 The inputs and thus the impacts to rivers from catchments (agriculture, forest) and the urban systems are varying distinctly and dynamically, depending on boundary conditions (e.g. precipitation, temperature, pH, soil water content), preceding conditions (e.g. duration of dry period), and events courses (e.g. gradients, duration, peaks, spatial and temporal variability, time of the day). While the hydraulics, their dynamics and the events loads with chemicals can be characterized rather well, the consequences for ecosystem health are still not clear nor explored. In the workshop, we aim at structuring the known unknowns and at shedding light on them from various perspectives and disciplines. Additionally, we will discuss potential topics and options to develop a cooperative initiative.
