Ever wondered about the secrets hidden beneath the tranquil waters of Berlin’s lakes? The Leibniz-Institut für Gewässerökologie und Binnenfischerei IGB holds the key. Right here before us stands a beacon of aquatic research. This isn’t just any building it’s a place where the mysteries of freshwater ecosystems are unveiled.
The IGB isn’t just a recent addition to Berlin’s landscape. Its history is rich. It traces its roots back to 1893. That year saw the founding of the Institute for Inland Fisheries in Berlin-Friedrichshagen. Its primary focus was studying inland fisheries. It also monitored water quality in the Müggelsee lake. By 1906 the institute’s responsibilities expanded. It included teaching fisheries and fish farming at Berlin universities.
Over the years other institutions merged to become the IGB we know today. These included the Institute for Geography and Geoecology in Leipzig. This institute had two departments in Berlin. One focused on hydrology in Adlershof. The other focused on aquatic ecosystems near Müggelsee. They researched surface and groundwater quality. They also explored physical limnology and mathematical modeling of aquatic ecosystems. Another contributor was the Central Institute for Microbiology and Experimental Therapy. Founded in 1959 this institute studied the ecological effects of the Rheinsberg nuclear power plant on the Großer Stechlinsee.
The IGB officially came into being on January 1 1992. This was after a recommendation from the German Council of Science and Humanities. Since then it’s grown into a leading international research center for inland waters. This remarkable institute employs around 400 scientists technicians and administrative staff. It boasts a budget of 14.7 million euros. Funding is split equally between the federal government and the state of Berlin. They also actively secure third-party funding.
The IGB’s work isn’t confined to the lab. They operate monitoring stations in Müggelsee Arendsee and Großer Stechlinsee. These stations continuously measure meteorological hydrological chemical and biological parameters. This includes data like global radiation wind speed and direction air humidity and water temperature. It also includes turbidity oxygen levels conductivity pH and chlorophyll-a concentration. This provides vital insights into the health and dynamics of these aquatic environments.
Perhaps the IGB’s most innovative project is ASTAF-PRO. Often called the “Tomato Fish” project it combines aquaculture (fish farming) with hydroponics (plant cultivation) in a closed system. This system saves energy water fertilizer and resources while minimizing environmental impact. The fish waste is naturally converted into fertilizer for the tomatoes. This closed-loop system offers a model for sustainable food production.
The IGB’s research touches on many crucial areas. They focus on the structure and function of inland waters. This includes biodiversity ecosystem services and responses to global change. The IGB significantly contributes to understanding these ecosystems. It supports sustainable management decisions. Its unique interdisciplinary approach brings together expertise from hydrology chemistry microbiology limnology ecology and fisheries biology. This allows for a more holistic understanding of freshwater systems.
The Leibniz-Institut für Gewässerökologie und Binnenfischerei stands as a testament to the power of scientific inquiry. It works to safeguard Berlin’s aquatic heritage. It’s a place where the future of freshwater ecosystems is being shaped. This is more than just research. It’s a commitment to a sustainable future for all.
