In an ICPO consultation, the IGB recommends that the salinity of the Oder should be made an important management issue. 

A study in Nature Cities shows that artificial light, together with urban heat, may be lengthening the growing season in urban environments by as much as 3 weeks compared to rural areas. Light pollution has a greater impact than urban heat, particularly at the end of the growing season. For the study published in Nature Cities, the researchers analysed satellite data from 428 urban centres in the northern hemisphere over a period of seven years.

IGB gave feedback in the Call for Evidence on the new EU Bioeconomy Strategy and highlighted the central role of water and freshwater ecosystems.

Light pollution, which illuminates the night sky, promotes the growth of cyanobacteria (often called blue-green algae) and stimulates metabolic processes in lakes. This is shown by a recent study by the Leibniz Institute of Freshwater Ecology and Inland Fisheries (IGB) in the largest field experiment to date on the effect of light pollution on lakes. The results have been published in the scientific journal Water Research.

IGB researchers gave feedback in the EU consultation on the GreenData4All initaitive.

Water is misused as a weapon when infrastructure and water resources are deliberately destroyed in armed conflicts. Water resources and infrastructure are also affected by the ongoing armed conflict in Ukraine: In June 2023, the Kakhovka Dam, which held water from one of Europe's largest reservoirs, collapsed as a result of military damage. Researchers led by the Leibniz Institute of Freshwater Ecology and Inland Fisheries (IGB) have now published a study on the ecological consequences of the dam collapse in the journal Science.

The River Spree flows in reverse direction in some sections. Subsequently, water from River Erpe, which contains partly treated wastewater from the wastewater treatment plant Münchehofe, can flow in reverse direction in River Spree into Lake Müggelsee. Such flow reversals, which will likely occur more frequently in the future due to the phase-out of lignite mining, climate change and deviated annual precipitation patterns, pose a challenge for water management.

IGB researchers gave feedback on the planned European Water Resilience Strategy and underlined the relevance of freshwater ecosystems.
