Dr Florian Humpenöder

Senior Scientist

Florian Humpenöder is a senior scientist at the Potsdam Institute for Climate Impact Research. He is a member of the land-use management group in Research Department III - Transformation Pathways.

Florian works with Integrated Assessment Models (IAMs) to develop global-scale transformation pathways compatible with the 1.5°C target of the Paris Agreement and the UN Sustainable Development Goals (SDGs). His core expertise are future scenarios of global land use under varying assumptions such as socio-economic development, land-use regulation, and dietary shift. Florian is an active developer of the open-source land-use model MAgPIE.

He published several peer-reviewed articles in high-ranking journals on the topic of GHG emission reduction from agriculture (e.g. methane from ruminants) and land-use change (e.g. CO2 from deforestation). Protection, management and restoration of forests and other ecosystems play a central role in his scientific work. He is a contributing author in the IPCC Special Report on Climate Change and Land (SRCCL) and the AFOLU chapter in the IPCC AR6 WG3 report.

Florian is currently working in the international EU-funded project WET HORIZONS.

Florian was part of the Expert Advisory Panel for The Earthshot Prize selection in 2023.

Florian Humpenöder studied economics at the Freie Universität Berlin (FU Berlin) and sustainable economics at the University of Kassel. He was awarded a PhD in economics from the Technische Universität Berlin (TU Berlin) for his thesis Land based climate change mitigation - Modeling bioenergy production, afforestation and avoidance of deforestation in 2015.

  • Transformation pathways for food and agricultural systems
  • Future pathways of global land use
  • Land-based mitigation (avoided deforestation, afforestation, bioenergy, peatlands)
  • Trade-offs between climate protection and sustainable development
  • Land-use model development (MAgPIE)

Contributing author to the IPCC Special Report on Climate Change and Land (SRCCL) and the AFOLU chapter in the IPCC AR6 WG3 report.
