Ecosystem Research, Geoarchaeology and Polar Ecology

Photo Rano RarakuHumans have influenced the development of the Earth's landscapes for a long time. Land use practices changed ecosystems. The cultivation of crops and livestock farming released traces in soils, in sediments and in the topography of the landscape. For thousands of years, people have been modifying the water balance and matter cycles by land use.

Due to their extreme environmental conditions and inaccessibility, the Arctic and Antarctic are still among the least studied regions on earth. However, the processes taking place here are not limited in their effects to the polar regions, but are of global importance.

Photo Polar EcologyWe use ecosystem research and geoarchaeological methods to investigate when, where, how and why people have used the Earth's landscapes and oceans. We investigate the consequences of land use and the interactions between human cultures and changes in ecosystems, as well as the effects of climate change and extreme weather events on ecosystems, land use and cultures.

Our research areas are located in Central, Southern, Southeastern and Eastern Europe, Turkey, Ethiopia, Siberia and the Arctic Ocean, in Latin America and on islands in the Pacific Ocean (Easter Island, Robinson Crusoe Island, Palau, etc.), the Atlantic Ocean (US Virgin Islands, Madeira, etc.) and the Northern and Southern Ocean.

The department publishes the international scientific journal Polar Biology (Springer).

Babeldaob (Palau, Micronesia): Investigation of genesis and function of prehistoric earthworks

Babeldaob is the largest island in the Micronesian Palau archipelago. The relief of a large part of the island is characterized by monumental, terraced earthworks. This anthropogenic transformation of the landscape is the earliest evidence of monumentality on the Pacific islands. According to the current state of research, the earthworks are at least 2000 years old. However, key questions about the chronology, genesis, function, and use of the terraced hills are still largely unanswered. Did the terraces serve as settlement areas? Have they been used for horticulture? Did they have a religious significance? Or were they use for defense? The three-year project funded by the German Research Foundation is now investigating these questions. The project is led by Hans-Rudolf Bork and Andreas Mieth (Institute for Ecosystem Research) in cooperation with Burkhard Vogt (German Archaeological Institute, Bonn). Project coordinator and excavation director in Palau is Annette Kühlem (Institute for Ecosystem-Research). more
