Dr. Sebastian Ostberg

PostDoc
Ostberg

Sebastian is a PostDoc in the working group "Adaptation in Agricultural Systems". His research background is in modelling the impacts of climate change and land use change on terrestrial biogeochemical cycles. In his current work, he focuses on impacts of climate change and weather on agricultural production. This includes developing a modelling pipeline for regularly updated global seasonal crop yield forecasts, but also looking at long-term climate change impacts on crop and livestock production.

Sebastian has also been active for more than 5 years in the Inter-Sectoral Impact Model Intercomparison Project (ISIMIP), contributing impact simulations with the LPJmL model and, for a time, working in the ISIMIP coordination team.

Sebastian received a "Diplom" degree (comparable to MSc) in Geoecology from Potsdam University. He did his PhD at the Potsdam Institute for Climate Impact Research and Humboldt-Universität zu Berlin and wrote his dissertation on the topic of "Joint impacts of climate and land use change on the terrestrial biosphere".

  • Short-term effects of weather and long-term effects of climate change on agricultural production
  • Impacts of climate change and land use change on the global terrestrial biosphere
