Floodplains can store and purify water. A team led by the Leibniz Institute of Freshwater Ecology and Inland Fisheries (IGB), in close cooperation with the Lower Oder Valley National Park, has investigated the role of the Oder's extensive floodplains for the water balance and the turnover of nutrients and pollutants. The results indicate that a permanent opening of the flooding weirs could be beneficial in order to keep at least some of the floodplains in contact with the river for longer periods of the year and maintain their important function.

A new IGB Dossier shows options for action for policy-makers and authorities at the nutrient-polluted Lake Arendsee.

Professor Dörthe Tetzlaff was today awarded the highly endowed Water Resources Award of the Rüdiger Kurt Bode Foundation. The prize, which is awarded every three years for outstanding work on the sustainable use of global water resources, honours Tetzlaff's pioneering research on the interactions between climate, land use, water quality and the ecohydrological processes that control water dynamics in landscapes.

To address the growing challenges posed by extreme droughts, researchers are focusing on ecohydrological processes in landscapes. They show that a better understanding of water storage dynamics at medium scales, i.e. areas between 10 and 100 square kilometres, could help to better predict and secure the availability of water resources, even in times of climate change. We spoke to Professor Dörthe Tetzlaff about drought resilience, the hidden water treasures of our landscapes, and more sustainable land and water management.

Die Hydrologin Dörthe Tetzlaff, Leiterin der Abteilung Ökohydrologie und Biogeochemie am Leibniz-Institut für Gewässerökologie und Binnenfischerei (IGB) und Professorin an der Humboldt-Universität zu Berlin (HU Berlin), ist heute mit dem Polubarinova-Kochina Hydrologic Sciences Mid-Career Award ausgezeichnet worden.

Using long-term monitoring data from 46 German lakes, researchers from IGB have shown that surface temperatures of lakes have risen faster than air temperatures over the last 30 years. Ooxygen concentrations in the deep water have decreased. Modelling suggests that this trend will continue. The good news is that the lack of oxygen in the hypolimnion would be alleviated if the nutrient loads from urban and agricultural discharges could be reduced.

Desiccating salt lakes are an underappreciated source of greenhouse gases that could become even more relevant as a result of climate change. Newly announced research by the Royal Ontario Museum (ROM) in the USA in cooperation with the Leibniz Institute of Freshwater Ecology and Inland Fisheries (IGB) examining greenhouse gas emissions from the drying lake bed of Great Salt Lake, Utah, calculates that 4.1 million tons of carbon dioxide and other greenhouse gases were released in 2020.

IGB researcher Mina Bizic has been appointed Professor and Chair of Environmental Microbiomics at the Technical University of Berlin (TU Berlin). We spoke to the scientist, whose work is dedicated to the smallest living organisms in water.
