Is there an "excess" of aquatic plants? IGB has now published a fact sheet to give all interested parties a brief research-based overview.

In spring 2022 , a research team from the IGB, together with students from the HU Berlin, conducted extensive groundwater investigations at Arendsee. The aim was to repeat a measurement campaign from 2012 to determine whether nutrient inputs to Lake Arend via groundwater have changed over the last 10 years. The results of the measurement campaign are now available.

Freshwaters are underestimated sources of greenhouse gases. Researchers with IGB have now shown that even dry water bodies can release considerable amounts of methane. An overview of the causes and magnitudes of methane emissions from freshwaters and an outlook on future developments in climate change make this evident: cleaner waters and more moorland, please.

German scientists have summarised in a policy brief what smart flood protection should look like and what benefits nature-based solutions in particular provide. 

Various pesticides, nitrate and climate warming – many stress factors for lakes and their creatures. A French-German research team has studied the individual and combined effects of these stressors on the food web of macrophytes, algae and microorganisms in shallow lakes. 

Dry banks instead of expanses of water, trickles instead of torrents. With climate change, freshwater bodies are losing water. Researchers of IGB are investigating what this means for people and ecosystems. Over the next few weeks, they will answer 10 questions on the topic.

Our planet is experiencing a dramatic decline in biodiversity. Freshwater plants and animals are particularly at risk. IGB scientists reveal where and why freshwater habitats are declining.
