Florian Ulrich Jehn

Senior Researcher at ALLFED

Florian Ulrich Jehn is a Senior Researcher in Environmental Science, with a strong focus on food security, climate, and civilisational resilience. They studied for their Bachelor’s and Master’s degrees in Environmental Science, with a specialization in hydrology and climate science, as well as studying soil science and ecology. Florian’s passion for understanding large-scale questions led them to complete a Doctorate in Environmental Science and Hydrology at Justus-Liebig-University Giessen in Germany, where they focused on using large hydrological datasets to understand river behaviour on different scales.

In their first postdoctoral position, Florian focussed on the study of extreme climate change and the changing research focus of the IPCC over time. Their current role as a researcher at the Alliance to Feed the Disaster (ALLFED) has allowed them to explore novel ideas that could potentially prevent global famine caused by catastrophic events. Florian’s research on this topic includes examining the feasibility of seaweed as a resilient food source after a nuclear war and exploring how planetary boundaries might interact with the effects of a nuclear winter.

Aside from their research work, Florian is also passionate about science communication. They regularly write a newsletter, “Existential Crunch”, and give talks and lectures to diverse audiences to raise awareness about the importance of food security and the impact of climate change on our planet.

Florian’s ultimate goal is to contribute to a sustainable future for humanity and the planet. They believe that by understanding the complex relationships between the environment, food systems, and civilisational resilience, we can develop innovative and effective solutions to address the pressing environmental challenges of our time.
