Dr. Constanze Werner

Postdoctoral Researcher

My current work focuses on the potentials and trade-offs of negative emission technologies. In scenario-based analyses I apply LPJmL to simulate the biogeochemical conditions and changes under large-scale employment of negative emission technologies. With these scenarios and impacts I aim to identify possible development pathways that mitigate climate change while maintaining land-systems, biodiversity and biogeochemical cycles. My previous publications describe the opportunity space for biomass pyrolysis/biochar in particular.

According to my focus on the concept of planetary boundaries as a methodological frame for the trade-off analysis, I operate within the TeSS group ("Terrestrial safe operating space"). In addition to the modelling approaches, I work on concepts of operationalization and scaling of planetary boundaries.
